| Using Tag Clouds to Promote Community Awareness in Research Environments | | BIBAK | Full-Text | 3-10 | |
| Alexandre de Spindler; Stefania Leone; Matthias Geel; Moira C. Norrie | |||
| Tag clouds have become a popular visualisation scheme for presenting an
overview of the content of document collections. We describe how we have
adapted tag clouds to provide visual summaries of researchers' activities and
use these to promote awareness within a research group. Each user is associated
with a tag cloud that is generated automatically based on the documents that
they read and write and is integrated into an ambient information system that
we have implemented. Keywords: Tag Clouds; Ambient Information; Community Awareness | |||
| A Proposal for Model-Based Design and Development of Group Work Tasks in a Shared Context | | BIBAK | Full-Text | 11-18 | |
| Fernando Gallego; Ana I. Molina; Crescencio Bravo; William J. Giraldo | |||
| The design and development of groupware systems is a difficult task,
especially due to their multidisciplinary nature and the technical complexity
of these kinds of systems (e.g. distribution, data sharing, multi-user
interfaces). A model-driven development approach could help to deal with this
research problem. This paper presents an approach to tackling the design and
development of groupware applications. This approach is part of a framework for
the model-based user interface development of collaborative applications
(called CIAF; Collaborative Interactive Application Framework), which includes
issues of particular relevance based on the use of several models and notations
for representing the collaborative and interactive aspects of this kind of
systems. Keywords: groupware design; model-based design; groupware production | |||
| Fixing Collaborative Edition on Typed Documents | | BIBAK | Full-Text | 19-26 | |
| Stéphane Martin; Denis Lugiez | |||
| Collaborative edition is achieved by distinct sites that work independently
on (a copy of) a shared document. In pure Peer to Peer collaborative editing,
no centralization nor locks nor timestamps, therefore convergence, i.e. all
sites have the same copy of the shared document, is the main issue. When the
editing operations defined on the data structure enjoy a commutation property,
efficient algorithms can be designed. The XML language provides a widely used
format for documents and these documents are usually typed by DTD's or XML
Schemas that are subclasses of regular tree languages. We extend a
collaborative editing algorithm that relies on a notion of semantics dependence
for operations and a tree data structure implementing XML documents to handle
type information provided by DTD's or XML Schemas (and more generally regular
tree languages). We show that the algorithm is convergent and that the final
document has the required type. Keywords: Peer to Peer Framework; CRDT; Collaborative Editing; Valid XML documents | |||
| Towards the Construction of a Knowledge Building Environment | | BIBAK | Full-Text | 27-30 | |
| Ruth Cobos; Raúl Cajias; Linda Barros; Marcos R. S. Borges | |||
| Nowadays, we can find a variety of Knowledge-Building Environments (KBEs). A
proposal of KBE for communities interested in generating a common corpus of
quality knowledge is presented in this work. This innovative KBE combines in an
integrated and complementary way the functionalities of two tested and
validated Knowledge Management Web-based systems: Sofia and KnowCat. On the one
hand, the Sofia system provides the ability to externalize tacit knowledge,
through the group storytelling approach. On the other hand, the KnowCat system
provides the crystallization of collective explicit knowledge thanks of its
Knowledge Crystallization mechanism. Keywords: Knowledge-Building Environment; Knowledge Management; Groupware; CSCW;

| Applying Situation Awareness Approach to Cooperative Play in Interactive Installation Storytelling System | | BIBAK | Full-Text | 31-38 | |
| Wen-Hwa Cheng; Chich-Jen Shieh; Yung-Hoh Sheu; Hsiao-Chuan Chang | |||
| Owing to its character of virtual reality situation, Interactive
Installation Storytelling System with Cooperative Play (IISSCP) provides
children an immersive environment and situation awareness (SA) to interact with
digital content more directly, intuitively, psychically and mentally. SA
improves the interactivity between children and digital content. Through the
interaction of play, children participate in learning willingly, give feedback
quickly and enjoy peer learning. By integrating virtual computer vision
applications with stage props as physical user interface, this system aims to
create a natural immersive situation to attain four setting goals which are
memory training, imagination of shape, music creation and training of physical
strength and reaction. The target users are children aged 8 to 12. However, the
cognitive differences of peers cause some problems during cooperative play.
Based on findings from this research, we discuss the problems causing
cooperation failure during play which are: (1) the cognitive differences when
using icons of user interface corresponding to physical user interface, (2) the
situation design affects role play during integrating the virtual and physical
user interface into a mental gestalt and (3) the interaction complexity and
difficulty affect children ability of situation awareness. Keywords: Situation Awareness; Interactive Installation Storytelling System;

| Memory and Creativity in Cooperative vs. Non cooperative Spatial Planning and Architecture | | BIBAK | Full-Text | 56-65 | |
| Dino Borri; Domenico Camarda; Rossella Stufano | |||
| Meanings and roles of memories and creativity in spatial organizations are
raising increasing attention among scholars and professionals. Creativity in
cognition-oriented spatial studies is gradually seen as a normal feature of an
organization. This thesis is supported, e.g., by the evidences on the role of
memory in the most creative parts of the activity of architects, combined with
exceptional association abilities representing the real bulk of creativity.
The present paper addresses the discussion of such issues, by analysing case studies of single-agent and multi-agent spatial organization under two levels of spatial navigation and space design. The paper explores possible modelling approaches and system architectures supporting cognition-oriented activities in spatial organizations.

| A cooperative platform is studied for improving the efficiency of road crack
detection. The platform is mainly divided into a mobile terminal with an
embedded road crack detection system, which detects pavement surface cracks,
and a control center which analyses the crack information and makes further
decisions. The experimental results indicate that this real time platform is
more efficient than classical road detection systems. Also a sample case of the
platform is given to show the road crack detection results and output. The
application of the road crack edge detection was realized in embedded Linux
system in the cooperative platform. The evaluation report will be output in
real time and sent to the central database from the embedded mobile terminal,
including the corresponding position information in the GIS of the cooperative
platform. Keywords: Pavement crack detection; Embedded Linux system; Real-time collaboration;

| Saving Energy with Cooperative Group-Based Wireless Sensor Networks | | BIBAK | Full-Text | 73-76 | |
| Miguel Garcia; Sandra Sendra; Jaime Lloret; Raquel Lacuesta | |||
| Wireless Sensor Networks (WSNs) can be used in many applications, but it is
most used in environmental monitoring. The energy consumption of each node
should be as low as possible, and the collaborative methods can improve their
performance. In this work, we compare the energy consumption of a regular WSN
with a WSN in which the nodes are organized in cooperative groups. We
demonstrate that cooperative group-based WSNs have fewer transmissions than
regular WSNs. Because higher energy consumption occurs in the transmitting and
receiving process of packages, collaborative group-based WSNs can have lower
global consumption. Keywords: Collaborative system; group-based WSNs; energy saving | |||
| Enhancing Collaboration in Vehicular Networks | | BIBAK | Full-Text | 77-80 | |
| J. Molina-Gil; P. Caballero-Gil; C. Caballero-Gil | |||
| A VANET (Vehicular Ad-hoc NETwork) is an ad-hoc network that allows
providing communications among nearby vehicles and between vehicles and nearby
fixed roadside equipment. In these networks, warning messages affect decisions
taken by drivers, so it is necessary the existence of a scheme to determine
whether the road traffic information available to the driver is trustful or
not. Besides, the quality of communications in VANETs is degraded when the
number of non cooperative vehicles is very large. For this reason, cooperative
groups are proposed as a solution to the spread of false traffic warning
messages, and reputation lists are presented to stimulate cooperation among
selfish nodes. Keywords: Cooperation; Reputation List; Reactive Group Formation | |||
| Initial Risk Assessment of Emergency Events in Cooperative Operating Control | | BIBAK | Full-Text | 81-88 | |
| Mieczyslaw Metzger; Grzegorz Polaków | |||
| It is often encountered some cases in the industrial control systems, where
emergency situations require a vital, irreversible, and relatively quick
decision, concerning further operations of the controlled process. The outcome
of the decision can be optimal if it is taken cooperatively by a group of
experts after careful assessing the risk of future hazards, taking into account
the depletion of resources caused by taken actions. For taking such decision,
an integrated environment is needed; in which geographically dispersed experts
could cooperatively test various control scenarios. In this paper the example
of a vital process is presented, i.e. an industrial wastewater treatment plant,
where a sudden increase in the content of toxic substances in the inlet flow is
the considered hazard. The proposed solution for the cooperative environment is
an agent-based framework, which supports the full integration of the JADE
environment with the numerical data acquired by OPC from industry-grade
instrumentation. Keywords: risk assessment; emergency management; distributed expertise; wastewater
treatment; cooperative operating control | |||
| The Sensitivity Analysis for Cooperative Decision by TOPSIS Method | | BIBAK | Full-Text | 89-96 | |
| Leonas Ustinovichius; Ruta Simanaviciene | |||
| Quantitative multiattribute decision making methods are handy for making
cooperative decisions, because the decision makers are interested in finding a
common solution; even some times they have diverse goals. The initial data for
cooperative decision making depend on the decision makers' own views, therefore
the input data may be inconsistent. An important step in cooperative decision
making is to perform a sensitivity analysis for the cooperative decision.
In this paper we perform a sensitivity analysis for the cooperative decision with respect to the values of attributes and the values of the attribute significances. The judgements of the expert group are used for generating the values of attributes significances. Monte Carlo simulation is used for the generation of the attribute values. We propose to represent the final decision together with the results of sensitivity analysis and confidence level of the decision. We believe that this can help to increase the reliability of the cooperative decision making. Keywords: cooperative decision making; diverse goals; sensitivity analysis; multiple
criteria decision; TOPSIS method | |||
| A Freshness Based Persistent Assurance Scheme for Secure Scalable Media Distribution | | BIBAK | Full-Text | 97-100 | |
| Yong-Hyuk Moon; Jae-Hoon Nah; Chan-Hyun Youn | |||
| Unlike a single-layer based media, maintaining data integrity of a scalable
media (SVC-encoded media) constructed as multiple layers is more difficult to
achieve due to a retransformation property of the scalable media. Moreover,
media redistribution among heterogeneous devices makes this issue more
critical. To provide consistency in data management, we newly define an
extended concept of data integrity as freshness in the standpoints of currency
and reuse of data. In this paper we propose how to generate freshness
information from the scalable media and describe a freshness-based persistent
control of verifying currency and reusability for reliably coping with media
retransformation and redistribution problems, respectively. Keywords: Data Freshness; Persistent Control; Scalable Video Coding | |||

| Group Formation through Cooperating Node in VANETs | | BIBAK | Full-Text | 105-108 | |
| C. Caballero-Gil; P. Caballero-Gil; J. Molina-Gil | |||
| Vehicular Ad Hoc Networks (VANETs) will play a vital role in the future road
safety and comfort. The lack of centralized infrastructure and high node
mobility and number of vehicles generate problems such as interrupting
connections, difficult routing, security of communications and scalability.
Groups are here proposed as a solution to avoid data collisions by decreasing
the number of connections exchanged among vehicles. To reach this goal, nodes
should cooperate with each other. They should form groups or join a group
depending on their state. This paper provides a global vision of the life cycle
of cooperative nodes who form groups and a description of how to deal with the
information within a group. Simulation results show that the proposed scheme
reduces the number of communications, avoiding data loss due to collisions. Keywords: cooperation; group; simulation | |||
| Scrum in Research | | BIBAK | Full-Text | 109-116 | |
| Martin Ota | |||
| The article is focused on research management and cooperation within the
research team and between the research team and enterprise (industrial or
commercial) partners. It is a kind of meta-research (research on a research
method). Roots of some problems of the current scientific research can be seen
in a lot of isolation that still endures -- both personal isolation of the
individual scientists, and isolation of the academic world from the
industrial/commercial one and vice versa that makes the scientific research
applied practically impossible --, and in bad time and/or resource management.
A lot of research activities are conducted by researchers itself who are
excellent professionals in the area of investigation, however the communication
skills or leadership is often lacking. It makes conducting research as
cooperation of a team at least inefficient or unmanageable. The article focuses
on Scrum method that is popular as a product oriented management method in
software development. It comments Scrum -- strictly team based activity, rigid
but informal -- as suitable candidate for management of some types of
scientific research. A special attention is devoted to the aspect of iterative
incremental deliveries that enable an operative planning of suitable ratio
between scientific and practical tasks for each iteration (usually from 2 to 4
weeks) allowing monitoring and controlling milestones, industrial or commercial
needs together with actual state of the research. A positive side effect is
that the potentially idle workers can share task of the 'opposite world', and
thus the experience of the scientist can be enriched by the real industrial
task cognition, and vice versa. The paper describes a Scrum implementation in
the scientific research, and shows some practical findings. A community web
site www.scruminresearch.org loosely grouping people and teams applying Scrum
in research is proposed as a conclusion. Such web site can help with sharing
information, tips and tricks and could allow collaboration of research teams on
tuning Scrum in research. Keywords: Scrum; Scrum in research; research methods; applied research;

| Recently, CAD data translation without loss of design intend using
commercial CAD data Translators is still impossible because these systems do
not have creation history and modification history of feature. Macro parametric
methodology is suggested as a solution of this problem, but critical problem
still remains. The reason of this problem is that topology-based macro can
cause an ambiguity in the name of feature. In this research, geometry-based

| Under the Ontology-based collaborative design framework constructed by OWL
and SWRL, in order to further extend the expression and reasoning abilities of
domain knowledge description and to achieve the reasoning based on fuzzy
theory, this paper expresses fuzzy domain knowledge by fuzzy logic and realizes
the reasoning to make the design process more intelligent. First, fuzzy
variables are formed by describing related fuzzy domain concepts and rules in
OWL and SWRL. Fuzzy sets which are described by membership functions are then
used to define fuzzy variables. At last, the fuzzy knowledge-based
collaborative product design is completed by using fuzzy reasoning. A case of
die selection shows the feasibility and intelligence of this approach. Keywords: Collaborative Design; Fuzzy Logic; Fuzzy Reasoning; OWL; Intelligent design | |||
| Technological Change: Educating for Extreme Collaboration | | BIBAK | Full-Text | 161-169 | |
| Vasilije Kokotovich; Tom Barker | |||
| This paper considers pedagogical strategies and techniques in design for
attaining sustained innovation collaboratively, in order to assist in the New
Product Design process and enhance opportunities for creating truly innovative
products. The authors argue that the New Product Design process demands a
multidisciplinary collaborative approach in order for designers to be able to
have a pro-active capacity for innovation. The central theme of this paper
relates to evidence for the hypothesis that it is the design teams who should
act as change agents, and that one catalyst for this is an Extreme
Collaborative Working model. This requires a further re-evaluation of the
benefits of teaching and working across the different disciplines of Industrial
design, Design Engineering and areas outside these domains. To cope with
operating in an increasing technologically turbulent context, future teaching
programs need to make creative connections between diverse design issues and
diverse resources. Keywords: Technological Change; Collaborative working; Design Teams; Multidisciplinary

| Zhiqiang Zhang; Xiaodong Zhang; Yingzi Li; Cancan Zhao | |||
| It is difficult for highway design enterprises to manage collaborative
highway design process due to its distributive and collaborative characters.
Aiming at this problem, a web-based project management system for collaborative
highway design was developed based on Project 2002 software. First, the
organization structure of the design team is formulated, and the design process
was analyzed and improved. Next, web-based project planning and controlling
methods were studied. Then, the system structure and functions are proposed.
Finally, a case study was illustrated to show the application of the system.
The application shows that the system can effectively control the collaborative
highway design process and improve the communication efficiency of the project. Keywords: Team organization; Web-based project management; Highway design | |||

for the ceramic industry. A new stakeholder playing a crucial role is now
included in the design process, i.e. the customer. Specifically, we present a
pilot validation study for the framework that aims to analyse how the
environment, experiences and reference criteria of different types of the
customers (commercial dealers, final users, architects and interior designers,
etc.) can affect their preferences. Information about these customer
preferences could be very useful for designers during the early stages of
product development. A multidisciplinary approach to the problem can introduce
substantial improvements in defining a truly collaborative design chain. Keywords: Collaborative Design; Customer; Subjective Impressions in Design | |||

| Virtual Reality (VR) technology could be applied as a complement to
three-dimensional (3D) modelling, leading to better communication whether in
vocational training, in education or in professional practice. Techniques of 3D
modelling and VR were applied to the development of models related to the
construction process. The 3D models created to support rehabilitation design
emerge as an important tool for the monitoring of anomalies in structures and
to assist decisions based on the visual analyses of alternative solutions. The
VR model created to help the management of lighting systems in buildings allows
the visual and interactive transmission of information related to the physical
behaviour of the elements, defined as a function of the time variable. Didactic
interactive models showing construction works were also developed. The
introduction of CAD and VR techniques in school is helpful to students in order
to prepare them to consider these technologies as important supports, later in
their professional practice. Keywords: Cooperative visualization; Engineering Education; Didactic Models; 3D

| Visualization of Neutral Model of Ship Pipe System Using X3D | | BIBAK | Full-Text | 218-228 | |
| Ikjune Kim; Guimok Cho; Jinsang Hwang; Jinggao Li; Soonhung Han | |||
| For ship-CAD data exchange among heterogeneous shipbuilding CAD systems such
as PDMS and Tribon, and for long-term archiving of data, we define a neutral
model for ship pipe model data.
For long-term archiving and for CAD data exchange, we make a pipe-design file using ISO10303 AP227, where the pipe-design file has information on the location and orientation of piping components. We created a catalogue database for the templates of every piping component in the ship-CAD using ISO15926 and we built a shape database for the shape of each component and specification files from a model of a commercial shipbuilding CAD system. We refer to these entities as pipe DESIGN file, CATALOGUE Library, SHAPE DB, and SPEC file, and together they comprise a "Neutral Model". In this situation, the neutral model is distributed in remote locations and local systems, as noted above. As such, it is difficult to check the archived status of specific piping components. Therefore, visualization of the neutral model is mandatory to check the archived status of the pipe model. In this research we extract pipe model data from a distributed neutral model and visualize the extracted data using X3D, a web based 3D graphics international standard.

| Jose P. Garcia-Sabater; Jaime Lloret; Juan A. Marin-Garcia; Xavier Puig-Bernabeu | |||
| One of the problems to be solved in manufacturing networks, with several
production centers, is the selection of a suitable manufacturer for each
component in order to obtain competitive costs while making full use of the
network's capacity. A solution is to own redundant information channels which,
despite offering the network greater resilience, generate high costs. The
coordination of the nodes in the manufacturing network could lower materials
and information flows, thus cutting lead times and total costs, and regulating
the system's total productive capacity. This work proposes a coordination model
that centralizes materials and information flows, and cuts the costs and
overall lead times. It also makes the self-adjustment of productive capacity
possible. Keywords: Manufacturing Network Coordination; Capacity Planning; ABM | |||

| In order to shorten new product development cycles, parallel approach is
emphasized to organize and plan the process of product design in Collaborative
Product Development (CPD), in which a great deal of constraints of
interdependent, interactive and restrictive relationships exist. The motivation
of this article is to provide a simple and effective method to solve this
problem. In new product development, collaboration is usually conducted
according to product structure. In accordance with this principle, a constraint
network is presented and an algorithm is given out. While the constraints can
not be met, then conflict will arise. A consultation model is established.
Finally, a case is put forward to explain how the algorithm for constraint
network and consultation model work. Keywords: constraint network; constraint algorithm; consultation model | |||

selecting candidates of cooperative product development team. Five attributes
including technical ability, innovation ability, cooperation ability,
experience level and credit level are proposed. Attribute cluster process is
presented in detail as well. Case study shows that the cluster analysis can
effectively reduce the configuration difficulty of the collaborative product
development team. Keywords: Cluster; candidate selection; cooperative product development | |||
| Collaboration Support in a Web-Based SCADA System | | BIBAK | Full-Text | 258-261 | |
| Grzegorz Polaków | |||
| This paper presents the approach to develop the SCADA system supporting the
expertise distributed amongst multiple persons. SCADA systems are briefly
presented and the analysis of sources of conflicts in the multi-user SCADA
system is provided. To assess the scale of conflicts two usage scenarios are
assumed, i.e. the collaborative environment for skilled engineers and experts,
and competitive environment for students and researchers. The implemented
solution allows the users to take exclusive control of specified parameter of
the plant by dividing the users into specific groups and using the token-based
mechanism. The proposed conflict resolution mechanism has been implemented in
the industrial pilot plant setup. Keywords: remote learning; cooperative research; multiuser system; conflicts | |||
| Collaborative Control of Hierarchical System Based on JADE | | BIBAK | Full-Text | 262-269 | |
| Dariusz Choinskim; A MichaÅ; A Senik | |||
| The paper deals with the design process supported by sharing information
through a Multi-Agent System environment. SCADA (Supervisory Control And Data
Acquisition) software systems are one of the typical applications in automation
industry and are used for monitoring, measurement and control systems. The
presented solutions are intended to enable collaborative control for automated
plants in a platform independent way. In the proposed Multi-Agent heterogeneous
system the OPC plays an important role as a powerful communication technology
especially dedicated for real-time distributed control systems. Based on the
OPC native protocol OPC Agents Ontology brings this automation communication
protocol idea into pure Java JADE Agents environment and also supports in
decision making process while participating in concurrent engineering process. Keywords: collaborative control; concurrent engineering; collaborative design process;

| Requirement Specification for Agent-Based Cooperative Control of Dynamical Systems | | BIBAK | Full-Text | 270-277 | |
| Witold NocoÅ | |||
| The paper presents requirements for a layer supervising the transition
between different agents controlling a dynamical system. Dynamical systems
often require uninterrupted control over certain parts of the process, for
which different control algorithm may be applied. Transition of control from
one agent to another is possible and may sometimes be desired. Therefore, it
must be ensured that the transition does not result in process deterioration.
The paper presents data structure and basic mechanisms that enable transition
of dynamical system control between different agents to be performed in a
desired way. Keywords: agent-based technology; dynamical systems; cooperative control and
monitoring | |||
| Web Engineering Process Matrix for Sustainable Deployment of Web-Based Applications | | BIBAK | Full-Text | 278-281 | |
| Sharil Tumin; Sylvia Encheva | |||
| Sustainable deployment needs a clear cooperative model of actors during
different phases of planning, design, implementation and maintenance for a
Web-based application project. Solving Web engineering problems involves
multifaceted working stages, multi-domains expertise and multidisciplinary
workers. The key to success is effective communication among actors. Actors can
be both active and passive, either humans or non-human entities. Cooperative
models can ensure effective flow of information between actors at all stages. Keywords: cooperative model; process matrix; sustainable deployment; Web-based
applications; effective communication | |||
| Collaborative and Visualized Safety Planning for Construction Performed at High Elevation | | BIBAK | Full-Text | 282-285 | |
| Nobuyoshi Yabuki; Petcharat Limsupreeyarat; Tanit Tongthong | |||
| To eliminate unsafe conditions and to reduce a number of accidents at
construction sites, engineers and supervisors in charge should have knowledge
related with the requirements of safety procedures and safety facilities of
construction activities performed at high elevation. Since the level and amount
of knowledge and experience depend on the person, engineers and supervisors
should discuss various aspects of hazards and safety collaboratively. While
supervisors should visit construction sites, they are usually too busy to pay a
visit to site. Thus, an innovative approach is needed to provide the engineers
and supervisors with a collaborative platform where some engineers are at the
site and some supervisors are the office and where they can see the options of
safety measures as well as the real construction site, for discussing safety
measures. This study aims to develop a visualized and collaborative approach
for simulating the construction activities operated at high elevation using
Augmented Reality. This research is on-going and the prototype system is under
development. The prototype will be tested at a real construction site. Keywords: collaboration; construction safety; augmented reality; falling | |||
| Product Precision Information Modeling under Cooperative Virtual Assembly Environment | | BIBAK | Full-Text | 286-293 | |
| Fengqiang Nan; Juntang Yuan | |||
| Considering the characteristics of cooperative virtual assembly process, the
product feature information is classified in this paper. A precision-oriented
cooperative virtual product assembly model is presented based on the tolerance
expression of the part feature. The model includes four layers: the
hierarchical relation layer, the connectivity relation layer, the feature layer
and the feature element layer. With the help of the relation chain within each
layer and the mapping information between the layers, different engineering
information is integrated. Finally, a new algorithm of automatic generation of
dimension chains in cooperative virtual assembly environment is described by
using searching mechanisms. Keywords: Cooperative visualization; Cooperative virtual assembly modeling; assembly

| Multi-mode resource-constrained project scheduling algorithm is widely used
in project static planning. However, in collaborative product development
projects, human is a kind of special resource in contrast to the technology
resource which should be considered separately. Starting from this point, this
paper introduces the designer-task-resource matching matrixes into the
multi-mode resource-constrained scheduling model. The mathematics model of the
problem was formulated and solved using a genetic algorithm. A case study was
illustrated based on the model. The result shows that the method can obtain the
minimum project duration by allocating most suitable person and resource to the
task under the constraints of task relations. Keywords: Task scheduling; Collaborative product design; Multi-mode | |||
