| Integrating Advanced Collaborative Capabilities into Web-Based Word Processors | | BIBA | Full-Text | 1-8 | |
| Haifeng Shen; Steven Xia; Chengzheng Sun | |||
| With the development of new web technologies, web-based collaborative applications, exemplified by office applications, are emerging to take advantage of web's attractive features. We propose to plug a collaborative engine into web-based office applications so that advanced collaboration capabilities can be seamlessly integrated without compromising or modifying their conventional capabilities. This engine lies on application-independent data addressing and operation models to be reusable for a wide range of diverse applications without being modified. In this paper, we present a data addressing model for web-based word processors, which complies with the model used by the engine and shall lay a good foundation for investigating data addressing models for other web-based applications. | |||

| Lirong Wang; Jiacai Wang; Lixia Sun; Ichiro Hagiwara | |||
| Efficiency and timeliness of collaborative communication among
geographically distributed design teams are vital to collaborative product
design for synchronous exchange of product design information and faster
product availability. This paper introduces a preliminary research work about
P2P&VRML-based collaborative communication environment that attempts to
support synchronous collaborative product design in the way of WYSIWIS (What
You See Is What I see). A prototype with communication means of document
co-sharing & editing, draft co-drawing, instant message and VRML-based
visualization space is developed on the basis of JXTA platform. Collaborative
model modification is performed by cooperation between document co-editing
space and VRML visualization. Keywords: Collaborative design; P2P; VRML; CSCW | |||

| Yue Wang; James Shearer; Kwan-Liu Ma | |||
| Large-scale scientific investigation often includes collaborative data
exploration among geographically distributed researchers. The tools used for
this exploration typically include some communicative component, and this
component often forms the basis for insight and idea sharing among
collaborators. Minimizing the tool interaction required to locate "interesting"
communications is therefore of paramount importance. We present the design of a
novel visualization interface for representing the communications among
multiple collaborating authors, and detail the benefits of our approach versus
traditional methods. Our visualization integrates directly with the existing
data exploration interface. We present our system in the context of an
international research effort conducting collaborative analysis of accelerator
simulations. Keywords: multiple location collaborative design applications; information

| This paper describes how information visualization techniques can be used to
monitor a web-based collaborative platform and to support workplace awareness
by providing a global overview of the activities. An innovative prototype is
described. Its originality relies on using some enclosure-based visualization
methods in the context of activities monitoring, which is rather unusual. In
addition, a new layout is described for representing data trees. The use of the
system is illustrated with the case of a EU-funded Network of Excellence. Keywords: Information visualization; collaborative platforms; treemaps; ellimaps | |||
| Workflow Methodology for Collaborative Design and Manufacturing | | BIBAK | Full-Text | 42-49 | |

| During product development processes, collaboration has become a common
practice between different departments and companies that are involved in their
activities. Product Lifecycle Management (PLM) tools can facilitate
collaboration among distributed teams within the context of an extended
enterprise, but the efficient use of them is still hard to achieve. In this
work, we propose a workflow based approach in order to implement product
development collaboration, focusing the discussion on a case study of the
integration of design and manufacturing activities, using workflow
functionality offered by PLM software. Keywords: Workflow Management; Collaborative Engineering; Extended Enterprise; Product

| Cooperative Reinforcing Bar Arrangement and Checking by Using Augmented Reality | | BIBAK | Full-Text | 50-57 | |
| Nobuyoshi Yabuki; Zhantao Li | |||
| In this research, a bridge product model named New IFC-BRIDGE was developed
to represent entities of various types of bridges in a standardized manner. To
solve problems identified in planning and design of reinforcing bar works, a
cooperative reinforcing bar arrangement support system using Augmented Reality
technology was developed. In this system, multiple users can move tangible
markers that represent entities of reinforcing bars and that are linked to
computer graphics images represented from the New IFC-BRIDGE product model
data. A prototype system was developed by deploying head mounted displays with
video cameras. Furthermore, to enhance the reinforcing bar checking task at
construction sites, a cooperative reinforcing bar checking support system was
developed by using AR technology. The test of the prototype system showed the
practicality of the system, and some problems were identified for future study. Keywords: Product Model; Reinforcing Bar; Augmented Reality; IFC; IFC-BRIDGE;

| Pieter Jorissen; Fabian Di Fiore; Gert Vansichem; Wim Lamotte | |||
| Analysis of existing ICT-based solutions for the education of long-term ill
children reveal several weaknesses with respect to social and cooperative
involvement, cost of development, and mobility issues. We present a scalable
and affordable solution that supports both the social needs and learning
process of these children. An educational platform was created based on the
concepts of 3D networked virtual environments and Virtual Interactive
Communities. In this work we describe the system architecture, network setup
and protocols, and how we implemented the educational support. Our solution
incorporates innovative hardware, software and connectivity features, set in a
user friendly user interface based on networking and 3D technologies. It helps
to establish high quality involvement of the long-term sick children in a
communication based scenario between the place where the child stays/has been
moved and their original classroom learning setting. Keywords: Cooperative Learning Environment; Edutainment; E-Health; E-Learning; Virtual

| Pro-active Environment for Assisted Model Composition | | BIBAK | Full-Text | 70-79 | |
| Sascha Opletal; Emil A. Stoyanov; Dieter Roller | |||
| Automatic testing and learning methods are of great benefit in many
engineering areas. They provide the possibility for training without the need
of personal communication and eliminate related barriers that hold up project
progress. As most technical systems include components that are related to each
other and need to form a properly working system, a knowledge base which allows
to retrieve the relations of a component to others regarding its properties and
targeted functionality can support this task in many ways. Our system for
assisted model composition forms a highly structured documentation system,
based on model semantics. An important aspect of our system is the combination
of user activated information retrieval and pro-active model composition
assistance. The model semantics define specialized dependency annotations that
can be attached to selected parts of the model, and with the help of which
relevant guidelines for related processes, such as model couplings, and
belonging remarks about materials, integration oddities, exceptions and other
dynamically defined properties, can be brought to the designer's attention. Keywords: Knowledge Management; Cooperative Learning; Error-Reduced CAD | |||

| Due to the numerous important decisions with major consequences which have
to be taken within a short period of time in case of disasters like fire,
terror attacks or floods up-to-date information about the site affected as well
as positions and activities of the deployed rescue teams should be available in
real-time. This information can firstly be gathered from Computer Aided
Facilities Management-systems (CAFM-systems), which are based on the graphical
and alphanumerical base data of the building, and are used to manage large real
estates and infrastructural installations in developed countries nowadays and
secondly by real-time data from master control systems and security
installations of the building. Thirdly data from an "inertio-tracker" based on
accelerometers and gyroscopes and used for tracking rescue teams within
buildings or underground constructions can be implemented to superimpose the
building data with actual position information.
The Institute for Building Informatics at Graz University of Technology in cooperation with the security industry is currently researching and developing such a CAFM-based Disaster Management System (DMS). The main challenges are locating and tracking persons, the local information management and the communication between the on-site staff and the command center. This paper gives a brief introduction and description of the whole system with a main focus of outlining the special aspects of an efficient and easy-to-use user interface.

| Organizations are under increasing pressures to manage all of the personal
data concerning their customers and employees in a responsible manner. With the
advancement of information and communication technologies, improved
collaboration, and the pressures of marketing, it is very difficult to locate
personal data is, let alone manage its use. In this paper, we outline the
challenges of managing personally identifiable information in a collaborative
environment, and describe a software prototype we call SNAP (Social Networking
Applied to Privacy). SNAP uses automated workflow discovery and analysis, in
combination with various text mining techniques, to support automated
enterprise management of personally identifiable information. Keywords: Privacy; compliance; workflow; social network analysis | |||
| A Scalable Method for Efficient Grid Resource Discovery | | BIBAK | Full-Text | 97-103 | |

| How to discover resource rapidly and exactly in distributed and
heterogeneous grid environment is a key problem that affects grid computing
performance. In this paper, the P2P method is used to improve scalability of
resource discovery mechanism, and a decentralized resource discovery method
with well scalability is presented, this method uses binary tree to manage
data, each node in grid is responsible for managing a part of resource
information. Experimental result shows that the method presented in this paper
can resolve many problems that exist in centralized mechanism, such as poor
scalability, heavy load on resource information server and single point
failure. Keywords: Grid Computing; Resource Discovery; P2P; Binary Tree | |||
| Modeling and Analysis for Grid Service Cooperative Scheduling Based on Petri Nets | | BIBAK | Full-Text | 104-112 | |
| Yaojun Han; Changjun Jiang; Xuemei Luo | |||
| As the complexity of application system for enterprises, an important
challenge is to dynamically schedule and integrate the heterogeneous and
distributed services or activities to work cooperatively and efficiently. An
effective technology to resolve the problem is grid service. A grid service
built on both grid computing and web services technologies is an extended Web
service. An application system for enterprises is a grid service composition
that consists of a collection of grid services related by data and control
flow. Therefore, there is a need for modeling and analyzing techniques and
tools for reliable and effective grid service composition. The Petri net based
method is an idea approach. In this paper, we use a colored dynamic timed Petri
net (CDTPN) to model the grid service composition. The definition of CDTPN for
grid service and an algorithm to construct a composite service are proposed. We
give a definition of reachable service graph and an algorithm for constructing
the reachable service graph of CDTPN. Finally, we discuss the correctness and
effectiveness of the grid service composition by analyzing the reachable
service graph. Keywords: grid service; composition; dynamic timed Petri net; performance analysis | |||
| Capturing Designers' Knowledge Demands in Collaborative Team | | BIBAK | Full-Text | 113-121 | |
| Zhen Lu; Jiang Zuhua; Liu Chao; Liang Jun | |||
| Collaborative team members usually come from diverse disciplines; their
demands for knowledge are also different from each other. This paper is mainly
concerned with how to capturing designers' knowledge demands in collaborative
team. With the view from workflow, designers' knowledge demand is modeled from
three aspects, members, roles, and tasks' requirements for knowledge. Based on
the model of knowledge demand, some intelligent mining methods are proposed so
that designers' knowledge demand could be derived automatically. With the
knowledge demand model, a knowledge supply system could be developed to
realize: knowledge within an appropriate domain could be delivered to the
proper user among the collaborative team. Keywords: Knowledge Management; Knowledge demand; Collaborative design; Workflow | |||
| "Integrare", a Collaborative Environment for Behavior-Oriented Design | | BIBAK | Full-Text | 122-131 | |
| Lian Wen; Robert Colvin; Kai Lin; John Seagrott; Nisansala Yatapanage; R. Geoff Dromey | |||
| In this paper, we introduce a new cooperative design and visualization
environment, called "Integrare", which supports designers and developers in
building dependable, component-based systems using a new behavior-oriented
design method. This method has advantages in terms of its abilities to manage
complexity, find defects and make checks of dependability. The environment
integrates and unifies several tools that support multiple phases of the design
process, allowing them to interact and exchange information, as well as
providing efficient editing capabilities. It can help formalize individual
natural language functional requirements as Behavior Trees. These trees can be
composed to create an integrated tree-like view of all the formalized
requirements. The environment manages complexity by allowing multiple users to
work independently on requirements translation and tree editing in a
collaborative mode. Once a design is constructed from the requirements, it can
be visually simulated with respect to an underlying operational semantics, and
formally verified by way of a model checker. Keywords: behavior-oriented design; behavior tree; software environment | |||
| Differential Conversion: DWG -- SVG Case Study | | BIBAK | Full-Text | 132-139 | |
| Martin Ota; Ivan Jelínek | |||
| This paper is focused on differential conversion, which is a new approach to
data transformation between different software systems. The strategy of
differential conversion, which is built on a log of changes and identifier
mapping, was introduced in CDVE 2006 in a purely theoretical paper entitled
Data Exchange in CAD during Iterative Work with Heterogeneous Systems. A
specific case study of differential conversion in use is elaborated in this
text. It is about an intelligent bi-directional transformation between DWG and
SVG. DWG is a proprietary CAD-format of the AutoCAD system, whereas SVG is an
open, generic graphics format, based on XML. The implemented transformation
allows usage of a model created in a CAD-system within a cooperative design
intended for non-CAD users. It is useful not only for reading, but even for
writing into the model and modifying it. Any changes made are returned back to
the original model. The following case exemplifies the previously discussed
strategy. For example, a project submitter, or another party in the review
process, can use a normal, generic SVG editor for writing comments and
proposals into the model. A solver can transform them back into the CAD-model,
without other entities in the model being damaged. This case study describes
differential export and import tools and takes note of the particular solutions
of the log of changes and identifier mapping problems. It also describes the
relationship to the original differential conversion proposal, discusses the
particular implementation, and again generalizes into some design pattern for
differential conversion implementation projects in the conclusion. Keywords: CAD; cooperative design; cooperative engineering; data exchange;

environment, which, in its turn, has attracted increasing attention of CAD/CAM
engineers. We aim to present our research results on a strategy of supporting
evolution of versions in a collaborative environment. The strategy we provide
is consists of a functional model which make application developing more
easier, a deployment model in which a Version Management Unit is the deploying
cell and a communication agent is included to exchange version information, a
storage model which support that version information is saved in space of
personal, group or global respectively. The topics discussed also in this paper
are definition of version status, the transform of version status, the storage
location of version and corresponding version operations. Keywords: collaboration; version control; model | |||
| Semantic Web Services Discovery System with QoS for Enhanced Web Services Quality | | BIBAK | Full-Text | 149-156 | |
| Okkyung Choi; Heejai Choi; Zoonky Lee; Sangyong Han | |||
| Semantic Web Services are the key technology providing services for the
users' convenience in the semantic web environment. Many companies in various
fields are researching and developing languages for constructing Semantic Web
Services such as DAML-S, WSDL, X-LANG and BPEL4WS. DAML-S is a method that
accesses the existing Web Service method from a semantic web environment.
However, the current Semantic Web Services Discovery System does not provide
sufficient processing of quality factors (performance, accessibility,
availability, reliability and transaction) nor reliable and accurate service
results desired by the user through a UDDI search method. The present study
analyzes the disadvantages of the current web services and suggests a Semantic
Web Services Discovery System based on QoS applying semantic web technologies
as a solution to the problems. The suggested system provides a UDDI and DAML-S
based discovery engine to allow efficient web service discovery and
composition. Keywords: Semantic Web Services; QoS (Quality of Services); Information Retrieval;

| As digital libraries become more popular, information and knowledge overload
has become a pressing yet required literature searching problem. Problems with
searching in digital libraries will become more complex as the amount of
information/knowledge increases. Traditional digital libraries often index
words and documents while learners think in terms of topics and subjects. As a
result, learners cannot determine how well a particular topic and/or subject is
covered, or what types of search methods will provide the required information
and knowledge without problems. In order to increase the efficiency and quality
of the Brita in PuBs project's activities, an Intelligent Library and Tutoring
System for the Brita in PuBs project (ILTS-BP) was developed. ILTS-BP has the
ability to personalize, maximize reuse, index, analyse and integrate valuable
information and knowledge from a wide selection of existing sources. Also, the
authors have integrated ILTS-BP with a Voice Stress Analyser Subsystem. ILTS-BP
is briefly analysed in this paper. Keywords: real-time system; knowledge management; multiple user; intelligent library

| Quality Information Management System Under Collaborative Environment | | BIBAK | Full-Text | 167-174 | |
| Junjie Yang; Rongqiao Wang; Jiang Fan; Xinmin Du; Zebang Zhang | |||
| Under collaborative environment based on PDM, the coupling of information
between PDM and QIMS makes the development of QIMS complicated. During
constructing cooperative circumstance, the development of QIMS can be
simplified through fusing rules of quality control into the processes managed
by PDM. On the other hand, since the joint model of processes managed by PDM is
equivalent to the virtual product model in the collaborative environment, QIMS
can also reach quality objectives of enterprise by controlling the quality view
of joint model. On the basis of the quality view, an integration model between
QIMS and PDM is designed to achieve the combination between quality management
and process management by information integration and interface. Keywords: collaborative environment; PDM; system integration; quality information

| Lei Wu; Xiangxu Meng; Shijun Liu | |||
| To meet the challenges of geographically and logically distributed
development processes. Manufacturing resources have to be encapsulated into
services. The paper presents an extensible resource encapsulation framework and
provides an approach to grid-enable manufacturing resources following Web
Service Resource Framework (WSRF) specification which can make them offer their
services and functionality in grid environment. The framework includes a
Resource Container Factory Service and many Resource Container Instance
Services. The same kinds of resources are deployed in one resource container
instance. The encapsulation framework has many advantages such as extensible,
plug-and-play deployment, automatic encapsulating and manageable. The paper
presents the design principle of the resource encapsulation framework. One kind
of resource container-resource container for legacy binary codes is introduced
as an example in this paper, which can cast legacy binary codes into web
services. At last, we give a use case to validate our method and put forward
the future work. Keywords: grid; service-oriented; manufacturing resource; Web Service Resource

| The bumpless switching is a concept from cybernetics. It refers to the
smooth switching condition when a new system replaces the old one in operation.
We implemented the dynamic reconfiguration of SoC based on delta MPU
architecture to reach a bumpless switching. The dynamic reconfiguration of SoC
with bumpless switching depends on a co-design of some bumpless switching
algorithm and a SoC hardware with delta core structure. Since bumpless is a
desired condition in system switching, the scheme is significant for the
dynamic reconfiguration of SoC. Keywords: bumpless switching; SoC; dynamic reconfiguration | |||

| In this study, an Agent-Based Collaborative Scheduling System is represented
as a model of scheduling among shops. Agent-based system describes the
behaviors of distributed decision maker agents in manufacturing systems. Agents
in the system are Production Planning Agent and Shop-Floor Agents. Shop-Floor
Agents are semi-autonomous agents so that the degree of autonomy is determined
by the Production Planning Agent. The distributed system forming heterogeneous
units was designed by hybrid control architecture. The study focuses on
constructing an Agent-Based Collaborative Scheduling System that is capable of
conducting scheduling negotiations among shop-floor agents. The designed system
is capable of scheduling by considering heterogeneous objectives of the
shop-floor agents within a collaborative manufacturing environment. Negotiation
is co-operative not competitive. Shop-Floor Agents generates collaboratively
their schedules. The schedule for the best interest of the system as a whole is
selected by the Production Planning Agent. Keywords: Agent-Based Production Systems; Collaborative Scheduling; Cooperative

| The determination of the investment project risk is an important stage in
cooperative decision-making and in choosing the most profitable project with
the lowest risk level in engineering and construction. Risk management is a
systematic process for integrating professional judgments about relevant risk
factors, their relative significance and probable adverse conditions and/or
events leading to identification of auditable activities. The paper aims to
present a verbal method of determining investment risk in construction. The
main problem considered is the assessment of investments, which depend on the
risk level. This article presents a new way to solve the problem -- the CLARA
expert verbal method. Formally, the problem is stated as one of multicriteria
classifications. A hierarchical approach to the considered effectiveness
indicators is proposed. The proof of the method effectiveness is presented. The
process of method's practical application is described. Keywords: expert verbal method; engineering and construction; cooperative decision

| This paper presents a document recommendation system based on clustering
peer-to-peer networks. It's an unstructured P2P system. In this system each
agent-peer can learn user's interest, then it helps user share and recommend
documents with the other users. Since each peer in our P2P networks is a node,
in order to cluster them, we import the concept of Group. Each group is
composed of peers. The types of documents, which belong to a same group, are
uniform. This paper presents how these peers help users to share and to
recommend documents, and how they cluster into groups. Our experiment results
show the advantages of the document recommendation system. Keywords: Recommendation System; Clustering P2P; Reputation Management | |||

| With the gradually extending of problem application scale, science and
engineering computing becomes more and more complicated. Designing a
collaborative problem solving environment aiming at specific fields is becoming
more and more important. In order to integrate various heterogeneous resources
and provide a flexible problem solving environment, we proposed a novel grid
approach: SECGrid (Science and Engineering Computing Grid). SECGrid provides a
dynamic grid application deploy environment. A grid portal is also adopted to
present grid application from diverse sources in a unified way. We proposed a
new scheduling algorithm (Application Demand Aware Algorithm) to make job
scheduling more feasible. Moreover, SECGrid provides a lot of useful
facilities, such as grid accounting, grid monitoring, etc. In the practical
application, SECGrid encapsulates lots of computing modules from science and
engineering, and provides an easy way for collaborative problem solving. Keywords: PSE; grid computing; grid accounting; grid monitoring; scheduling | |||

In such systems, node periodically exchanges media block availability and
fetches desirable blocks from neighbors. The issue on optimizing fetching
blocks is called block scheduling and receives focus, especially in
heterogeneous overlay. In this paper Bandwidth-Aware Scheduling (BAS)
formulates such problem by incorporating bandwidth and block deadline, as well
as node importance. Simulation results verify that BAS performs much better
than existing ones. Keywords: Peer-to-Peer; Media Streaming; Block Scheduling; BAS | |||

| In a global world we face the necessity for worldwide collaboration and
long-term co-creation. We know different kinds of internet platforms and
examples of successful remote team work within projects for a limited time but
we do not have much experience about computer sustained communities working
successfully beyond projects and generations with different cultures and
conflicting interests. The challenge is to build and to maintain a very
specific kind of virtual community realizing a successful mix of "real"
(face-to-face) and "virtual" (remote) qualities creating a platform for
successful dialogue between diverse points of view. The contribution describes
key qualities for creating such communities. It is about how to build the
bridge between technical potentials and human qualities for establishing
cross-cultural and long-term processes beyond face-to-face work. The presented
experiences are based on the creation of an open and frank dialogue culture
consequently using cooperative visualization from the first step of the
collaboration process. Keywords: Community; network; networking; virtual; real; visual; cooperative

to the implementation and underlying technologies of MaGIA, an Internet-based
multi-user system designed for a collective and collaborative construction of
knowledge models represented as concept maps. The use of the system can cover a
wide range of purposes, from a theoretical discussion and construction of
formal models to a support for collective brain-storming
. What makes MaGIA an interesting tool is the emphasis put on a collective construction of such maps. In fact, one of the distinctive features and objectives of the system is to offer an enabling tool for a multi-user, bottom-up construction, where users can intervene, freely contribute and extend concept maps and where collective and collaborative multi-user map construction can take place in asynchronous as well as in synchronous way.

| Collaborative simulation technology is an important factor in improving the
efficiency of complex product design. Although High Level Architecture
(HLA)-based simulation technology can meet the needs for simulation in product
design, it's also marked by many deficiencies. In this paper, we focus on the
introduction of web services into HLA simulation system and propose a Web
Services-Based HLA Collaborative Simulation Framework (WSHLA). The framework
uses web services to encapsulate the invocations of HLA services and then make
simulation system more interoperable and reusable. Firstly, the overall
structure of WSHLA and the proxy, which acts on behalf of a federate and
interacts with Runtime Infrastructure (RTI), are presented. Then, the detailed
design and implementation process of WSHLA are discussed. Experimental results
show that, using web services, the framework can make up for the deficiencies
in HLA simulation system and ensure WSHLA-based collaborative simulation goes
smoothly at the expense of some time. Keywords: web services; high level architecture; collaborative simulation framework;

| The team of engineers designing and implementing distributed control system
software must communicate within a multidisciplinary environment. One of the
main problems is the interaction between hardware and software solutions.
Software project presumptions may not be based only on minimum hardware
requirements and on technology rules. Modern distributed control systems
embrace all aspects of a complex and widespread object. Hence, every
modification within any discipline requires interference into the system and
validation of its new features, which in turn constraints effectiveness of
designing. This paper discusses how to increase effectiveness and speed up
validation, in a standardised CAD environment, by using: Multi-Agent System in
order to limit the number of interactions between particular subsystems,
ontology for assisting topology description and properties of system entropy
for assessment of introduced solutions. The proposed system was implemented and
worked out in a biotechnological pilot plant. Keywords: Collaborative design; multi-agent systems; knowledge ontology; web

| A Two-Level Programming Method for Collaborative Scheduling in Construction Supply Chain Management | | BIBAK | Full-Text | 290-297 | |
| Xiaolong Xue; Chengshuang Sun; Yaowu Wang; Qiping Shen | |||
| There are increasing requirements for collaborative scheduling (CS) in
supply chain management (SCM). CS in construction supply chain (CSC), which
involves multiple partners, such as general contractor, subcontractors, and
material suppliers, can be seen as a multilevel decision-making system with
hierarchical structure. Adopting the decomposition-coordination thought of
large scale system theory and using the multilevel programming theory, a
two-level programming model for CS decision making is established to find
satisfactory solution for every partner in CSC. This model has the merit of
paying attention to the maximization of profit or minimization of cost of all
partners located at different decision-making level in CS process. The
algorithm of this model is provided, which is combined with the first level
programming adopting simulated annealing algorithm and second level programming
using discrete search algorithm. Finally, an illustrative example of CS in a
CSC is presented. The two-level programming method provides a new way to
improve collaborative decision making in CSC. This research makes a
contribution to the body of knowledge of scheduling. Keywords: Collaborative scheduling; Two-level programming; Supply chain; Construction

| Edmundas Kazimieras Zavadskas; Valentinas Podvezko; Algirdas Andruskevicius; Leonas Ustinovichius | |||
| Steady pace (rhythmicity) of work is a relevant parameter reflecting the performance of production systems. A coefficient (index) of the steady pace is used for quantitative evaluation of a production system's performance. Various rhythmicity indices often yield different and even conflicting results. The application of logically consistent axioms to a set of indices allows us to identify indices accurately describing a steady pace of production. A case study of rhythmicity of suspended aluminium ceilings' manufacture at one of the enterprises over the period of 5 years divided into quarters and months is provided. | |||

| Resource Sharing and Remote Utilization in Communication Servers | | BIBAK | Full-Text | 331-339 | |
| Guofeng Qin; Qiyan Li; Xiuying Deng | |||
| The communication cluster servers require many key technologies in an
information integration platform. In order to improve dependability,
scalability, and other QoS features, we design a system structure to meet these
requirements. The resource sharing and remote utilizing are applied to
resolving the dynamical resource dispatch and the tasks distribution. The
thread model and mechanism of the thread pool in the Non-blocking Input/Output
(NIO) are created which include a case trigger mechanism. The system
successfully resolves thousands of terminals connected to the information
integrated platform. Messages, files, data, and other information can transport
among the platform, the clients and the terminals. Keywords: Cooperative server cluster; resource dispatch; concurrent processing; real

| Leveraging Single-User Microsoft Visio for Multi-user Real-Time Collaboration | | BIBAK | Full-Text | 353-360 | |
| Kai Lin; David Chen; Chengzheng Sun; R. Geoff Dromey | |||
| Microsoft Visio is one of the most prevalent commercial single-user graphic
editing systems, which can be used to create a wide variety of business and
technical drawings. It is desirable to leverage single-user Visio system for
multi-user real-time collaboration. One feature that distinguishes Visio from
other graphic editing systems is that formulas, a type of constraint, are
defined in Visio to express the attributes of each graphic object, and the
relationship between different Visio graphic objects. The ability to describe
shapes with constraints opens many possibilities for making shapes behave in
complex and sophisticated ways, but satisfying constraints in the presence of
concurrency in collaborative systems is a challenge. In this article, we
introduce a collaborative Visio system, called CoVisio, which enables a group
of users to view and edit the same Visio documents at the same time from
different collaborating sites. The methods applied to develop CoVisio are
generic and can be adopted to leverage other single-user systems that support
constraints, such as Microsoft Excel, for multi-user collaboration. Keywords: Collaborative Visio; Consistency maintenance; Constraint satisfaction | |||

| Web-Based Engineering Portal for Collaborative Product Development | | BIBAK | Full-Text | 369-376 | |
| Shuangxi Huang; Yushun Fan | |||
| Nowadays, collaborative product development has become a strategic necessity
to develop high quality products at low cost and with quick response time to
market demand. Past decades have seen significant advances to collaborative
product development. However, Enterprises are still confronted with some
problems. Firstly, the research in strategic level of collaborative product
development is lacking. There are no formal processes and models for
collaborative product development. On the other hand, the full alignment
between information system and collaborative business is still missing. The
information system cannot adapt to the fast changed business. This paper aims
to provide the strategy and reference business model for collaborative product
development. And then, to support the implementation of strategy and model, a
workflow and web service based engineering collaboration portal is developed.
The workflow is used to model and execute the collaborative product development
processes, and the web service is the implementing technology of the portal.
The combination of workflow and web service can fit the gap between business
and information system and achieve on-demand business. Keywords: Web-based; portal; collaborative product development; web service | |||
| Application of Paraconsistent Logic in an Intelligent Tutoring System | | BIBAK | Full-Text | 377-384 | |
| Sylvia B. Encheva; Sharil Tumin; Maryna Z. Solesvik | |||
| Experience shows that testing students' understanding of new concepts
immediately after they have been introduced considerably improves the learning
process. In this work understanding of a concept is assumed to take place if a
student can provide reasonably correct answers to questions requiring
application this concept. A possible solution to the problem of how to
determine whether students actually understand a concept is to give them tests.
Such tests, being a part of an intelligent system, provide inconsistent
information to intelligent agents, facilitating the tests evaluation process.
This happens because the degree of a student's understanding varies a lot
depending on factors like time and the way questions are formulated. Since
classical logic fails to draw conclusions in the presence of inconsistencies we
propose application of paraconsistent logic. Keywords: intelligent infrastructures and automated methods; logic | |||

| Collaborative testing is an effective way of distributed interoperability in pursuit of automated testing. In this paper, a novel collaborative testing approach named Collaborative Automated Testing Framework (CATF) which meets the requirements of not only automated testing but also collaborative operation is proposed. Through the abstract analysis in terms of extended dynamic dataflow (DDF) model's viewpoint incorporating with UML2.0 profile of MDA, we design the framework with an automated engine working as a Finite State Machine (FSM). Particularly, as a approach to collaborative testing at a system level, CATF is implemented with component modules based on J2EE and verified to be of efficiency. | |||
| IT Services Design to Support Coordination Practices in the Luxembourguish AEC Sector | | BIBAK | Full-Text | 396-403 | |
| Sylvain Kubicki; Annie Guerriero; Damien Hanser; Gilles Halin | |||
| In the Architecture Engineering and Construction sector (AEC) cooperation
between actors is essential for project success. The configuration of actors'
organization takes different forms like the associated coordination mechanisms.
Our approach consists in analyzing these coordination mechanisms through the
identification of the "base practices" realized by the actors of a construction
project to cooperate. We also try with practitioners to highlight the "best
practices" of cooperation. Then we suggest here two prototypes of IT services
aiming to demonstrate the value added of IT to support cooperation. These
prototype tools allow us to sensitize the actors through terrain experiments
and then to bring inch by inch the Luxembourgish AEC sector towards electronic
cooperation. Keywords: AEC; Cooperation Process; Coordination practices; IT services | |||

| Cooperative learning is a social interaction that involving a community of
learners and teachers, where members acquire and share experience or knowledge.
Recently, researchers have initiated studies that explore which factors are
relevant to learner satisfaction or education effectiveness in a cooperative
learning environment. However, little research effort for developing a
cooperative learning platform for information system training, such as
three-dimensional CAD system training. Thus, our study aims to narrow these
gaps. We present the cooperative learning platform for 3D CAD system. This
approach can be helpful for better establishing cooperative learning for
information system training. We introduce a case involving three-dimensional
CAD training with the web-based cooperative learning platform in China. This
research is specifically related the context of a state-of-the-art cooperative
learning platform that is based on network technology for real-time interaction
amongst users, instructor, and the cooperative learning system itself. Keywords: Cooperative learning; Three-dimensional CAD; Knowledge management | |||

| A Relative Entropy Method for Improving Agent-Based Negotiation Efficiency of Collaborative Working in Construction Projects | | BIBAK | Full-Text | 426-428 | |
| Xiaolong Xue; Jinfeng Lu; Yaowu Wang; Qiping Shen | |||
| This research presents a relative entropy method for improving agent-based
multi-attribute negotiation efficiency (REAMNE) of collaborative working in
construction projects (CWCP). This method aggregates preference information of
negotiators of CWCP in two steps. Firstly, compromise group preference order is
ascertained by using preference information, which is newly provided by
negotiators, and compromise preference information, which is formed in
previously agent-based automatically negotiation process and calculated by
using a compromise preference model. Secondly, group preferences are aggregated
by using a relative entropy model, which is established based on entropy theory
meanwhile considering the multiple attributes in negotiation of CWCP. The
method of REAMNE has the merit of fulfilling the necessary requirement of group
decision making (GDM), i.e. maximizing preference consistency of GDM and
keeping minimum gap of negotiators' utility and group preference. Keywords: Collaborative working; Agent; Negotiation; Relative entropy | |||
