Synthetic Environments for Cooperative Product Design BIBAKFull-Text 1-10
  Egon L. van den Broek; Frank Meijer; Jan Miedema; Huaxin Wang; Mascha C. van der Voort; Joris S. M. Vergeest
Synthetic Environments (SE) facilitate an easy setup of various virtual realities since they are component-based and relatively easy maintainable. Through three stages, involving various types of stakeholders, the feasibility of SEs for cooperative product design (CPD) was explored: 1) Semi-structured group interviews with 19 engineers and designers assessed SE's potential for CPD; 2) Implementation of a SE; 3) Comparison of a SE with its real counterpart, through: a) an experimental task and b) questionnaires to determine the task performance, the mental workload, the experienced spatial presence, involvement, and realness. 16 participants had a similar task performance, mental workload, and involvement but differed in experienced realism (F(1,30)=5.11, p=.03) and spatial presence (F(1,30)=7.02, p=.01). This research emphasizes the benefit of SE for CPD, which can increase the communication, speed and quality of CPD. Hence, a first step is made towards a new era of CPD.

Cooperative Design Using Haptic Interaction and 3D Visualization BIBAKFull-Text 11-19
  Benoît Otjacques; Marc Krier; Fernand Feltz
Cooperative design is increasingly used in engineering but this generic term regroups very diverse approaches and technologies. This paper explores a quite recent trend aiming to study how multimodality can support cooperative design. More specifically, a prototype combining 3D visualization and haptic interaction is described. The potential of this approach is illustrated with the example of mobile phone design. This research also identifies several technological questions that must be solved before being able to transfer this approach to a real industrial context.
Keywords: 3D Visualization; Haptic Interaction; Cooperative Design
"SketSha" -- The Sketch Power to Support Collaborative Design BIBAKFull-Text 20-27
  Catherine Elsen; Pierre Leclercq
This paper presents a new supporting tool for distant collaborative design, named SketSha. This prototype supports the early stages of design and more particularly the initial and crucial step of free-hand sketching. SketSha and its particular interface, named the virtual desktop, aim to keep from Front-To-Front collaborative work all the benefits and to appoint to them some of the nowadays IT facilities, in order to manage in a realistic and efficient way a long distance collaboration and to effectively serve the designers' needs. Our hope is to re-introduce the social aspects and group interactions, crucial for real system efficacy and adaptation to the business world. The paper presents the fundamental assumptions made to implement SketSha, that are questioned and analyzed through a real-size experimentation featuring 30 architecture and building engineering students, working together in real-time in different locations (Belgium and France). This experiment and the necessary survey open up interesting fields of investigations, such as the relevance of the sketch stage and the proposed device to support distant collaborative design in architecture and the benefit it represents for students, in a pedagogical point of view, to merge the IT aspects and the design studio. The methodology and the replicability are analyzed to increase the level and quality of our students' formation and, finally, a critic of SketSha constitutes a benefit for the developing teams.
Keywords: Distant and Synchronous Collaborative Design; Architecture support device; Sketches support tool
Application of Parallel Programming in Collaborative Design BIBAKFull-Text 28-35
  Tieming Su; Xiaoliang Tai; Zhixiang Xu
Aiming at improving the design and assembly efficiency of complex products in collaborative design, this paper proposes a parallel assembly model which is based on parallel computing. It divides assembly task into subtasks according to main branch in the virtual-link structure, and finally the subtasks run in parallel. This model supports large scale design, improves the speed and at the same time improves the computing resource utilization of collaborative design in Grid environment. A collaborative design prototype system based on Grid, which takes hybrid CSG/B-Rep model as geometric kernel, is developed to realize parallel assembly. Experimental results obtained from Lenovo DeepComp 1800 System are displayed and analyzed.
Keywords: Collaborative design; parallel computing; virtual assembly; Grid
Collaborative Explorative Data Analysis Applied in HTML BIBAKFull-Text 36-44
  Mikael Jern
This paper introduces a Visual Analytics framework for the support of collaborative explorative data analysis (EDA) based on task-relevant visualization components embedded in HTML documents. The goal of our research is to let the analyst visually explore and search the answers to various questions about data and simultaneously capture and save important discoveries and thus enable collaboration and sharing of gained insights and knowledge to remotely dispersed team members over the Internet. A team will benefit from an interactive collaborative instrument that can "coach" them in the understanding and testing of hypotheses leading to faster understanding and a higher confidence level in the visual information. The foundation for this approach is based on the publicly available GeoAnalytics visualization framework and class library (GAV).
Keywords: Visual analytics; collaboration; explorative data analysis; HTML
Cooperative Visualization of Privacy Risks BIBAKFull-Text 45-53
  George O. M. Yee; Larry Korba; Ronggong Song
The growth of the Internet has been accompanied by the growth of e-services (e.g. e-commerce, e-health). This proliferation of e-services has put large quantities of customer private information in the hands of service providers, who in many cases have mishandled the information to the detriment of customer privacy. As a result, government bodies have put in place privacy legislation that spells out the privacy rights of customers and how their private information is to be handled. Service providers are required to comply with this privacy legislation. This paper proposes a cooperative visualization technique that can be employed by service providers to understand how private information flows within their organizations, as a way of identifying privacy risks or vulnerabilities that can lead to violations of privacy legislation. The description of the technique includes a model of how an e-service uses private information, a graphical notation for the visualization, and an application example.
Keywords: Cooperative visualization; privacy risks; privacy legislation; privacy compliance; security; e-services
An Ontology-Based Semantic Cooperation Framework for Business Processes BIBAKFull-Text 54-57
  Yue Ni; Shuangxi Huang; Yushun Fan
Nowadays many functions within intra- and inter-enterprises have been encapsulated into Web services to enable platform independent integration and interoperation. To realize the enterprise applications, most Web services are composed as workflows based on Business Process Execute Language (BPEL). However, the absence of semantic information in processes reduces the efficiency of interoperation and cooperation among these Web services from different providers. In this paper, a novel framework to support semantic cooperation of business processes is proposed, which brings semantic information into processes through mapping OWL-S to BPEL and Web Service Definition Language (WSDL) documents, then Web services from various domains and enterprises can understand each other eventually. The framework is being implemented under Project ImportNET.

A Framework for Tolerance Analysis in Collaborative Engineering Mechanical Design BIBAKFull-Text 58-65
  Carles Riba Romeva; Roberto Pérez; A Luis W. Hernández-G.; A Joaquim Ciurana-G.
Nowadays, the global competitive environment has a special impact on small and medium enterprises (SMEs). The development of computer and network technology has provided opportunities for researchers to construct and build systems to support collaborative engineering design in a concurrent manner. A special issue related to the development of design tools to improve the quality and productivity is the tolerance analysis evaluation through the lifecycle of the product. In response to this context, the tools should be collaborative and flexible. This paper shows the development of a framework to concurrent tolerance analysis evaluation through the lifecycle of the product in collaborative engineering mechanical design.

Peer-to-peer collaboration over XML documents BIBAKFull-Text 66-73
  Claudia-Lavinia Ignat; Gérald Oster
Existing solutions for the collaboration over XML documents are limited to a centralised architecture. In this paper we propose an approach for peer-to-peer collaboration over XML documents where users can work off-line on their document replica and synchronise in an ad-hoc manner with other users. Our algorithm for maintaining consistency over XML documents recursively applies the tombstone operational transformation approach over the document levels.
Keywords: XML; collaborative editing; peer-to-peer collaboration; operational transformation
Cooperative Scenario Building in Environmental Planning: Agents, Roles, Architectures BIBAKFull-Text 74-83
  Domenico Camarda
The new complexity of planning knowledge implies innovation of planning methods, in both substance and procedure. In this concern, an increasing number of experiences on multi-agent interactions is today located within processes of spatial and environmental planning. Case studies have not been deliberately set up using formalized and/or predefined multi-agent-system layouts. Therefore, a multi-agent approach and supporting system (MAS) emerged in a bottom-up fashion, driven by the needs demanded by the activities carried out. However, such approaches have not been formalized properly to date. The present paper aims at scanning experiences on the setting up of cooperative multi-agent systems, in order to investigate the potentials of that approach on the interaction of the agents in planning processes.

Towards a Platform for Cooperative Creation of Scientific Publications BIBAKFull-Text 84-88
  Guilherme Saraiva; Orlando Carvalho; Benjamim Fonseca; Hugo Paredes
Writing scientific publications is usually a challenging and complex activity, involving several authors. Despite the different natures of their contributions, this activity is clearly collaborative and the collaboration is usually achieved through face-to-face meetings and using email to exchange the documents. More recently the availability of collaborative editors introduced a further step in the collaboration, but none of the existing solutions contemplate some specific issues like referencing and publishing adequately. This fact motivated us to conduct a study to evaluate the requirements for a platform that integrates in a single solution the three main functionalities required: a text editor, a reference manager and a connector to scientific digital repositories.

A Cooperative Simulation Framework for Traffic and Transportation Engineering BIBAKFull-Text 89-97
  Paulo A. F. Ferreira; Edgar F. Esteves; Rosaldo J. F. Rossetti; Eugénio C. Oliveira
As contemporary intelligent transportation systems are becoming a reality in our everyday's life and future urban transportation brings about concerns of a wide range of new performance measures, multidisciplinary teams are more and more faced with the need to work collaboratively so as to meet those demands. This paper reports on the specification of the MAS-T2er Lab framework, emphasising on its ability to support collaborative simulation and different perspective analyses of the complex and dynamic application domain of traffic and transportation in major urban areas. The architecture underlying all subsystems within the framework is discussed on the basis of the multi-agent systems metaphor, and a practical overview of its use is presented.

A Collaborative Model for Wireless Sensor Networks Applied to Museums' Environmental Monitoring BIBAKFull-Text 107-116
  Lina M. Pestana Leão de Brito; Laura Margarita Rodríguez Peralta
The major functions of the Wireless Sensor Networks (WSNs) cannot be accomplished without collaboration among sensor nodes. However, most of the work found in literature only focuses on a specific type of collaboration, associated with the accomplishment of a certain task, such as: sensing, signal processing, computing, routing, etc. In this paper, we present a graph-based model of collaborative work for WSNs. This model is called Wireless Sensor Networks Supported Cooperative Work (WSNSCW) and was created for the specific case of WSNs. We also present the formalization of some of the entities of the model and of its properties. This is a generic model that is being used as a basis for the development of a 3D web-based awareness tool for WSNs. In this paper, the model is applied to the specific case of a WSN created in a museum for artwork conservation.

Mixed Reality-Mediated Collaborative Design System: Concept, Prototype, and Experimentation BIBAKFull-Text 117-124
  Rui Wang; Xiangyu Wang
This paper introduces a Mixed Reality-mediated Collaborative design system, named MR-Collab, which combines Mixed Reality (MR), Augmented Reality (AR) and various channels of communication technologies. The concept and system of MR-Collab are developed based on the Benford's Mixed-Reality boundaries theory. This paper presents how this theory is used as a tool to analyze the system framework and guide the design of the MR-Collab system. The technique details of prototype and application scenario of this system are also elaborated in the paper. The system, MR-Collab, is designed in the purpose of facilitating collaboration between distributed users through the Mixed Reality environment. Experimentation that can measure the correlations between the design performance/behaviors with the increased degree of co-presence is also planned in this paper.

Decomposition of Information for Plant Collaborative Design and Set-Up BIBAKFull-Text 125-132
  Dariusz Choinski; Mieczyslaw Metzger; Witold Nocon
A problem of coordinating engineers working in different fields during design and control of an industrial installation is especially difficult during start up and modification of the process. Any work carried out in such a case must be coordinated in real time. Moreover, level of access to information is differentiated for different branches of engineers. In this work a hybrid agent-based system for cooperative plant design and set up of the biotechnological pilot plant is proposed. The major contribution deals with decomposition of biotechnological plant information by hybrid agent system for enhancing cooperation of experts having different knowledge about the process. Hybridization of the process is performed considering nine states, while estimation of the information distance is performed based on partial Kullback-Liebler cross-entropy function. Experience gained during design and exploitation of the mentioned biotechnological pilot-plant suggests this solution to be promising.
Keywords: Collaborative design and set-up; expert cooperation; hybrid agent-based system; decomposition of information; information distance estimation
ActivePlace, a Unified Collaboration Environment BIBAKFull-Text 133-141
  Yu You; Panu M. Åkerman; Suresh Chande
As Workplaces are being equipped with communication-oriented software more and more people are faced with the need to handle with multiple communication contexts in environments with ever increasing multi-tasking nature. The increased complexity of managing communication in different contexts is becoming more demanding than ever before. This paper presents a unified collaborative system named ActivePlace, which enables context-awareness in communication and collaboration. In this paper we discuss the new design we applied compared to the traditional online room-based workplace systems, such as use of context-aware extended presence and the concept of activity awareness for places. The ActivePlace provides an infrastructure for communication and collaboration in a context-sensitive basis.

Private Data Discovery for Privacy Compliance in Collaborative Environments BIBAKFull-Text 142-150
  Larry Korba; Yunli Wang; Liqiang Geng; Ronggong Song; George Yee; Andrew S. Patrick; Scott Buffett; Hongyu Liu; Yonghua You
With the growing use of computers and the Internet, it has become difficult for organizations to locate and effectively manage sensitive personally identifiable information (PII). This problem becomes even more evident in collaborative computing environments. PII may be hidden anywhere within the file system of a computer. As well, in the course of different activities, via collaboration or not, personally identifiable information may migrate from computer to computer. This makes meeting the organizational privacy requirements all the more complex. Our particular interest is to develop technology that would automatically discover workflow across organizational collaborators that would include private data. Since in this context, it is important to understand where and when the private data is discovered, in this paper, we focus on PII discovery, i.e. automatically identifying private data existant in semi-structured and unstructured (free text) documents. The first part of the process involves identifying PII via named entity recognition. The second part determines relationships between those entities based upon a supervised machine learning method. We present test results of our methods using publicly-available data generated from different collaborative activities to provide an assessment of scalability in cooperative computing environment.

Cooperative Multisite Production Re-scheduling BIBAKFull-Text 156-163
  Jaime Lloret; José Pedro García-Sabater; Juan A. Marin-Garcia
One of the main issues in cooperative enterprise planning and scheduling is how to re-assign tasks without involving too many components of every enterprise and implying too many changes in the whole system. We propose a new system that is able to re-schedule tasks in cooperative multisite production automatically avoiding one of the main problems that have schedule programmers that are in charge of two or more cooperative enterprises. The system is based on making virtual groups of machines that perform the same tasks and establishes links between machines from different groups. We will describe the algorithm in detail and we will validate it using a case of study. Results show that our proposal gives better performance.
Keywords: Scheduling; Cooperative decision making; Supply chain; cooperative-group-based model
Visualizing HLA-Based Collaborative Simulation System Modeling with a UML Profile BIBAKFull-Text 164-171
  Hengye Zhu; Guangyao Li
Collaborative simulation conduces to the efficiency improvement of complex product design. Modeling, especially visualization modeling, is among the most important steps in building a collaborative simulation system. Applying Unified Modeling Language (UML) to High Level Architecture (HLA)-based collaborative simulation system will lead to a better visualization, understanding, design and construction of the system. A UML Profile for HLA-based collaborative system modeling (UML-HLA) was proposed to extend UML on the basis of HLA-specific characteristics. Firstly, we presented the overall structure of UML-HLA, and then the stereotypes, tagged value and theirs constraints in UML-HLA were introduced. Using UML-HLA may model HLA-based collaborative simulation system visually, precisely and effectively.

3D Reconstruction of Large Scale City Models as a Support to Sustainable Development BIBAKFull-Text 172-175
  Jean-Philippe Pons; Souheil Soubra
No part of the economic community can now escape from the urgent issues related to global warming, carbon footprint and reducing energy consumption. Nevertheless, the construction sector is particularly under pressure. Indeed, it is one of the biggest consumers of energy. It also largely contributes to the massive use of some critical resources (such as energy, water, materials and space...) and is responsible for a large portion of greenhouse gas emissions. In that context, the paper explores new approaches for urban planning by combining Virtual Environments and Simulations to address sustainability issues. These approaches are based on the possibilities of reconstructing 3D models of the built environment using standard photographs taken with off-the shelf hand-held digital cameras. The 3D models can then be combined with simulations in order to address sustainable urban development issues.

The Application of Stochastic Dominance to Sensitivity Analysis in Quantitative Multiple Criteria Decision Making (MCDM-1) BIBAKFull-Text 184-191
  Leonas Ustinovichius; Ruta Simanaviciene
The paper considers sensitivity of multicriteria decision making methods based on quantitative measurements and their use in determining effective construction investment projects. The problem of effective construction investments is of paramount importance for a group of people (experts) making a cooperative decision because these investments determine the potential of construction and the structure of expenses. Similar problems also arise in other fields of engineering. The calculation of investments is an expensive tool of enterprise management used in planning the investments. The paper describes the main principles of sensitivity analysis of the initial data, i.e. the significances of the criteria elicited from the survey of experts using quantitative multiple criteria decision methods. Monte Carlo method as well as a particular form of stochastic dominance are also applied and the algorithm and a case study demonstrating the application of the suggested technique are presented.
Keywords: Cooperative decision making; quantitative methods; Monte Carlo method; stochastic dominance; multiple criteria evaluation

Using CIAN for Specifying Collaborative Scripts in Learning Design BIBAKFull-Text 204-211
  Francisco Jurado; Ana I. Molina; William J. Giraldo; Miguel A. Redondo; Manuel Ortega
The standardization of eLearning environments and the design of collaboration scripts are two research areas that are acquiring a greater attention within the Computer Supported Collaborative Learning (CSCL) community. IMS Learning Design (IMS-LD) is the specification used to describe instructional strategies. In this paper we analyse the suitability and lacks of IMS-LD for modelling collaborative learning processes. Based on this result, we propose a reference model inside the IMS specifications core and the use of a graphical notation called CIAN (Collaborative Interactive Applications Notation) as CSCL scripting language. Using these specifications of a high level of abstraction and mappable to a computer-interpretable notation such as IMS-LD, allows hiding the particularities of the standard to instructional designers.

Cooperative, Cross-Discipline Teaching and Learning BIBAKFull-Text 216-224
  Vasilije Kokotovich
This paper will discuss the outcomes and findings of a cross-discipline research experiment, which was a pilot study aimed at developing cross-discipline teaching modules within science and industrial design. A central aim was to develop teaching techniques that would equip science students with creative conceptualisation skills and strategies that lead to innovation in science, and provided industrial design students with insights into next-generation nano-technologies that can be explored and used as components within innovative artefacts. Early results suggest that there was a positive effect in the development and enhancement of cross-disciplinary teaching modules. Cross-discipline cooperative lectures and practical sessions were developed and tested on focus groups of science students and industrial design students. Video-taped data of the study provided feedback. This data was critically analysed. This valuable data/feedback informs new cross-disciplinary teaching methodologies and strategies. Analysis of the student comments revealed that both groups of students highly valued the new learning experiences. It is argued that working cooperatively and jointly in the co-development of cross-faculty teaching initiatives will improve the quality of teaching, via interactions that introduce and develop alternative teaching practices. While cooperative design may well refer to a cooperative set of designers within the same general disciplines, this example extends the view to demonstrate the importance of cooperative practices between disciplines.

Applying Web 2.0 Design Principles in the Design of Cooperative Applications BIBAKFull-Text 229-236
  Niels Pinkwart
"Web 2.0" is a term frequently mentioned in media -- apparently, applications such as Wikipedia, Social Network Services, Online Shops with integrated recommender systems, or Sharing Services like flickr, all of which rely on user's activities, contributions, and interactions as a central factor, are fascinating for the general public. This leads to a success of these systems that seemingly exceeds the impact of most "traditional" groupware applications that have emerged from CSCW research. This paper discusses differences and similarities between novel Web 2.0 tools and more traditional CSCW application in terms of technologies, system design and success factors. Based on this analysis, the design of the cooperative learning application LARGO is presented to illustrate how Web 2.0 success factors can be considered for the design of cooperative environments.

A Grid Based Collaborative Design System BIBAKFull-Text 237-244
  Tieming Su; Xiaoliang Tai; Weizhen Zhang; Zongying Ou
A collaborative design system architecture based on Grid is proposed. The architecture can take full advantage of grid features such as computing capability, massive data storage and device sharing etc., which is more suitable for the development of a complex collaborative design environment compared with the widely used Distributed Component Object and existing Grid based collaborative design architectures. Under this architecture, the construction method of Grid services is researched. Parallel and distributed Grid computing technology is used to increase the efficiency of complex product design. A collaborative modeling method based on XML is put forward to support real-time modeling by using design semantics instead of 3D solid model data transport. Finally, a collaborative design prototype system based on Globus Toolkit 4.0 is presented and analyzed.

A Collaborative Tool for Capturing, Sharing and Connecting User Research Study in Design BIBAKFull-Text 257-264
  Chujit Treerattanaphan
The objective of our project is to build a web based tool for generating a valuable design user research resource. User research is a process of discovering desirable and undesirable users' needs and expectation from a product or service. This user research information provides crucial sources of research insights, which lead to a process of finding ideas about functionality, features, criteria, and design attributes of a product or service. Usability testing is also considered as a part of the user research process to verify the feasibility of the design. The proposed Capturing, Sharing, and Connecting User Research (CSCUR) tool can help the design researcher to record and utilize user data efficiently. CSCUR tool provides a keyword list and procedure used as a guideline for design researchers to investigate related issues that need to be considered in design process, leading to an innovative design and responding to users' needs. Searching functionality facilitates activities in exchanging ideas and encouraging teamwork among the design research community.

Cooperative Internet-Based Experimentation on Semi-industrial Pilot Plants BIBAKFull-Text 265-272
  Mieczyslaw Metzger; Grzegorz Polaków
In this work a framework for cooperative experimentation with semi-industrial pilot plants is presented. A software solution designed to support multi-user cooperative experimentation is described, along with the supporting hardware, which was specifically designed for the task. A structure of dual networking is proposed, with horizontal real-time protocol for hardware integration and vertical multi-user access points for human interaction. To avoid potential conflicts between users, prioritisation is performed, as resources available (time, hardware, and data) are limited. An important sub-problem is described in details, i.e. large groups of students splitting into smaller subgroups, collaboratively performing partial experiments in order to achieve solution of problem stated by an instructor. Work and data flows have to be carefully designed to keep control of the collaboration an example of such schedule is provided and described.

Architecture Modelling of Large Cooperative Environments BIBAKFull-Text 277-280
  Martin Ota; Ivan Jelínek
The article is focused on the architecture of large cooperative ICT environments. The logical levels are the most important feature in the architecture. The paper introduces a system of three logical levels: the business architecture level, the application architecture level and the physical architecture level. Each level can contain several views -- either complete or partial views. Each level can have more than one instance. It provides a seamless platform for modelling how the business processes of collaborative engineering are running onto the architecture. UML is used as the modelling language. The instructions on how to use it are presented in the paper.

Cooperative Design Workflows for Multiphysics Applications BIBAKFull-Text 281-285
  Toàn Nguyên; Jean-Antoine Désidéri
This paper is devoted to the distributed workflows as a means to support large simulation applications, such as aircraft in flight dynamics. We are interested in the description of physics, their modeling in adequate tools, implementation and their deployment and execution on wide-area networks. This requires a layer where application codes are deployed and must be run cooperatively in distributed and parallel environments. We advocate the use of distributed and composite workflows in order to achieve effective and seamless large-scale simulation.

Cooperative Security Schemes for Mobile Ad-Hoc Networks BIBAKFull-Text 286-294
  Pino Caballero-Gil; Candelaria Hernández-Goya
The existence of selfish nodes, who do not cooperate in routing and forwarding, is one of the most critical problems for the applicability of Mobile Ad-hoc NETworks (MANETs). In this paper we propose several novel currency-based methods for stimulating cooperation among nodes of a MANET. In particular, the proposed protocols allow improving different aspects of previous schemes based on virtual currency thanks to the incorporation of the concept of credit that will allow broke nodes to use the network while they have not a selfish behaviour. A complete analysis of simulations leads to several conclusions that establish the improvement of the proposal with respect to previous schemes.

Towards a Cooperative Visual Authoring Environment for Storytelling BIBAKFull-Text 299-306
  Ivan Blecic; Arnaldo Cecchini; Giuseppe A. Trunfio
In this paper we present a methodological approach and a client-server software authoring environment for cooperative visual creation of story-outlines. The methodological approach adopted for story outlining facilitates the representation and visualisation of relevant aspects of stories in a way that is easy to use and understand, and enough general to admit a large number of types and genres of stories. Additional design objectives were set in order to support effective cooperative work and rapid story prototyping.
Keywords: Storytelling; cooperative story-outlines; visual cooperation; multiple user collaborative design
Cluster Computing in Drug Logistic Monitoring and Management BIBAKFull-Text 307-310
  Guofeng Qin; Qiyan Li; Xiuying Deng
We applied the cluster computing as a key technology for a drug logistic information system that we developed. In order to improve the dependability, scalability, and other QoS features of the server cluster, resource dynamic dispatching, task distribution, and workflow controlling were among the key issues that we focused in our development.
