Building a CSCW Infrastructure Utilizing an M&S Architecture and XML BIBAFull-Text 1-13
  Jenny Ulriksson; Farshad Moradi; Mattias Liljeström; Nicholas Montgomerie-Neilson
CSCW applications provide virtual spaces for human-human cooperation. Within Modelling and Simulation (M&S), CSCW support is highly beneficial but, as in most single-user applications, not natively provided. External support, such as infrastructures for creating or adapting applications for collaborative work, is generally missing in the CSCW community. At the Swedish Defence Research Agency we study the possibilities of defence CSCW, for the primary intention of collaborative M&S. Since most of our M&S complies with the HLA (a distributed simulation architecture), HLA appeared as a candidate for building a CSCW infrastructure upon. Thus we have designed and developed a prototype of a CSCW infrastructure, based on a combination of HLA and XML. The goal is to provide a foundation for developing CSCW applications, and for adapting existing applications to collaborative work. This paper presents the design and development, and experiments conducted for verifying utilization of HLA and XML for the purpose.
Modelization of a Communication Protocol for CSCW Systems Using Coloured Petri Nets BIBAFull-Text 14-21
  Éric Garcia; Julien Henriet; Jean-Christophe Lapayre
Concurrency management protocols are implemented over collaborative platforms in order to manage the shared object modifications. We have defined the Chameleon protocol which allows us to obtain a dynamic management of collaborative architecture. Now, we want to use this algorithm over a telemedicine platform within a European project on tele-diagnosis for neurology: TeNeCi. In such a domain, a robust (no errors, no losses...) management of interactions between cooperative members is crucial. Indeed, TeNeCi must provide an efficient and infallible tool to doctors in order to establish a collaborative diagnosis. So, we must validate and prove the Chameleon robustness. Coloured Petri Nets allowed us to correct the Chameleon weaknesses we have discovered during this modeling. Indeed, a time-out and an automatic forwarding mechanisms have been implemented in the first version of our communication protocol. In addition, a timestamp has been added to some messages sent to inactive sites. Finally, a lock mechanism during a particular step has been also implemented in the Chameleon. Due to those results, we have proved that our protocol is robust. Thus, it can be used in medicine applications.
The Design of a Workflow-Centric, Context-Aware Framework to Support Heterogeneous Computing Environments in Collaboration BIBAFull-Text 22-29
  Jinqiao Yu; Y. V. Ramana Reddy; Sentil Selliah; Vijayanand Bharadwaj; Sumitra Reddy; Srinivas Kankanahalli
Networked based distributed collaboration has become pervasive and makes today's enterprises much more productive than ever before. The automation of the collaborative processes can be driven and managed by workflow rules. In addition, during recent years, ubiquitous computing and universal network connectivity have imposed another imperative requirement on collaboration systems. That is, remote participants with heterogeneous and dynamic connection and process capabilities should be able to join seamlessly in the collaboration at any time. Intelligent, context-aware, and workflow-centric collaboration is an essential prerequisite to fulfill that requirement. In this paper, we describe a generic framework, dubbed as EkSarva, which is capable of embedding workflow rules and context-awareness intelligence into collaborative sessions leading to increased opportunities for process automation.
Do Tangible User Interfaces Impact Spatial Cognition in Collaborative Design? BIBAFull-Text 30-41
  Mary Lou Maher; Mi Jeong Kim
Developments in digital design workbenches that combine Augmented Reality (AR) systems and tangible user interfaces (TUIs) on a horizontal display surface provide a new kind of physical and digital environment for collaborative design. The combination of tangible interaction with AR display techniques change the dynamics of the collaboration and have an impact on the designers' perception of 3D models. We are studying the effects of TUIs on designers' spatial cognition and design communication in order to identify how such tangible systems can be used to provide better support for collaborative design. Specifically, we compared tangible user interfaces (TUIs) with graphical user interfaces (GUIs) in a collaborative design task with a focus on characterising the impact these user interfaces have on spatial cognition.
Cooperation in Highly Distributed Design Processes: Observation of Design Sessions Dynamics BIBAFull-Text 42-51
  François Laborie; David Jacquemond; Matthieu Echalier
In the recent years, industrial design programs have shifted from a co-located, sequential process to a globally distributed, concurrent process. Therefore, communication and coordination within and among teams have become major challenges. Surprisingly, several studies demonstrate that collaborative tools exist but are very seldom deployed nor used. Indeed, co-located working sessions remain a critical cooperation milestone for otherwise remote teams. In order to better understand the dynamics of those meetings, and identify what makes them so critical for the design process, we analysed working sessions of aeronautical design teams. This article reports the results of our observations based on three criteria: information types, information flow and interactions performed.
   Our study shows the critical importance of private communication channels, and investigates how they relate to the working session's process. It highlights the need of parallel visualization channels for cross-references, and analyses the use of interactions depending on ownership and context.
Designing Display-Rich Environments for Collaborative Scientific Visualization BIBAFull-Text 52-60
  Kyoung Shin Park; Yongjoo Cho
This paper presents a design study evaluating the shared workspace for Amplified Collaboration Environments (ACEs). ACE is a display-rich project room that enables distributed teams to work together in intensive collaboration campaigns. The study involved small groups of users performed a collaborative visualization and analysis task while varying the technology configuration for ACE's shared workspace. The result showed the participants benefited from the ability to see others' work, which helped enhance group awareness and performance.
Visualization of Interactions Within a Project: The IVF Framework BIBAFull-Text 61-70
  Benoît Otjacques; Monique Noirhomme-Fraiture; Fernand Feltz
Almost all projects can be considered as cooperative undertakings. Their strategic management as well as the daily operations causes numerous interactions to occur, either among persons or among persons and resources. These interactions have been studied from various viewpoints but few researchers have focused on their visualization. The graphical representation of the cooperation is however a powerful tool to help the project participants to get a correct understanding of the situation. This paper proposes thus a structuring framework (IVF -- Interaction Visualization Framework) of the visualization techniques used to display such interactions. Three basic axes of classification are used to structure the study. Which objects are visualized? Why are they visualized? How are they visualized? For each axis, several properties have been identified and the admitted values have been specified. This work can be considered as a first step towards a structured view of the 'visualization of cooperation' domain.
An Interaction Interface for Multiple Agents on Shared 3D Display BIBAFull-Text 71-78
  Jeong-Dan Choi; Chi-Jeong Hwang
In the multi-user VR game, wide stereoscopic display is an important component that supports immersion and perception to the gamer. Because the space in front of the display allows multi-participants to collaborate and guarantees view with the entire field of view for each user. This paper describes a method to integrate user interfaces for interactions among users wear VR devices on wide stereoscopic display. The key technologies of our proposed system include the problems of coordination with various devices to treat user events in real-time, synchronization of PC clusters which renders the VR contents, and seamless display of multi-channel display surfaces. To accomplish this, we propose a VR game display platform composed of multi-projectors, stereoscopic see-through head mounted device, and gesture recognition system for collaborative interactions. Our preliminary results showed that the proposed strategy well suits high resolution application at real-time frame rate for VR game.
Concurrency Control and Locking in Knowledge Base for Rapid Product Development BIBAKFull-Text 79-85
  Dieter Roller; Marian Mesina; Constanza Lampasona
Rapid Product Development (RPD) is a product-development technique that includes experts collaborating in a multi-disciplinary environment. Products consist of components. A component can be used in various products. These can be represented by a network structure (semantic network) consisting of vertices (objects) and edges (relations). Modifying a vertex can change other vertices within the network. In the Active Semantic Network (ASN) these modifications are propagated automatically. The RPD-Information is stored in the ASN knowledge base. Changes of referenced objects should be automatically taken into account within the ASN-database. Reciprocally, changes of an object attribute should lead to modifications in the referenced files. For the synchronization, object-lock mechanisms and access-control to the knowledge base are necessary. The concept presented here allows locking objects and also individual attributes. Object status and attributes allow regulating the access and the necessary steps for consistency re-establishment after system crash.
Keywords: Active semantic networks; locking; concurrent engineering; rapid prototype development (RPD); Knowledge basis consistence
Collaborative Solution for Cooperation, Coordination and Knowledge Management in the Ceramic Tile Design Chain BIBAKFull-Text 86-93
  Carlos Vila; Fernando Romero; Vanesa Galmés; María Jesús Agost
This paper presents a solution for cooperation between companies that belong to a supply chain in the ceramic tile sector, where competitiveness requires constant innovation in product design. Since it is becoming ever more frequent for these companies to design products and work collaboratively within the framework of the Extended Enterprise, a need arises for a methodology for the successful implementation of collaborative practices. The main contribution of this research work lies in the definition of a collaborative infrastructure for cooperative design that enhances interaction and knowledge management between different firms using information technology tools and, particularly, PLM solutions. The methodology used to achieve an efficient implementation is based on process modeling. Design processes are not always structured; there are continuous changes due to engineering modifications, and this fact makes modeling harder. Consequently, the definition of collaborative processes will allow a deeper understanding of product development activities.

GCE: Knowledge Management Applied in a Design Reengineering Process BIBAFull-Text 94-102
  Jonice Oliveira; Jano Moreira de Souza; Mauricio Lima; Ricardo C. Farias
In order to reach competitive advantage, manufacturing firms need not only to coordinate business and cross-border activities, but must also integrate and improve internal processes, coordinate access to internal and external knowledge, exploit and develop their employees' capabilities. In a manufacturing context, there are several levels
  • (equipments ↔ processes ↔ products ↔ market) which are related, and the competitive advantage and success in the market depends on the synergy of these levels. In all phases, we have people and specific information associated, and the handling of specific information by people, in a context, together with a usage experience, comprises knowledge creation. In this work, we describe a case at a Brazilian Oil Company. This company was losing knowledge on its first level of the manufacturing chain. In this paper, we will describe this problem, as well as the procedures to solve this problem, and the Knowledge Management environment created to support the process.
  • A Constraint Maintenance Strategy and Applications in Real-Time Collaborative Environments BIBAFull-Text 103-110
      Kai Lin; David Chen; Chengzheng Sun; R. Geoff Dromey
    A constraint expresses a relationship among one or more variables. Constraints are very useful in the development of collaborative applications, such as collaborative CAD and CASE systems, but satisfying constraints in the presence of concurrency in collaborative systems is difficult. In this article, we discuss the issues and techniques in maintaining constraints in collaborative systems. In particular, we also proposed a novel priority strategy that is able to maintain both constraints and system consistency in the face of concurrent operations. The strategy is able to resolve constraint violations in multi-constraint systems and is independent of the execution orders of concurrent operations. To illustrate the applicability of the proposed priority strategy, the applications of the approach in various collaborative systems are discussed in detail.
    Design of a Cooperative Working Environment for Mobile Devices BIBAFull-Text 111-118
      Miquel Mascaró; B. Estrany; J. Laredo; Eric Sidaner; Yuhua Luo
    GEMMA is a cooperative control system developed to manage and coordinate a fleet of mobile resources (boats, planes, employers, etc) dedicated to maintain clean coastal and beach waters in the Balearic Islands. All the process is supervised by a control center in several workstations. In addition, a cooperative working environment was designed and developed for a group of mobile devices. In this article we present a project extension that involves the control tasks of mobile computers. Using portable computers, PDA and mobile phones, controllers can develop their control tasks supervising the coastal state and be online with all the system and resources in the Gemma project. All the communication processes are established by TCP-IP connections via GPRS/UMTS.
    Mobility in Environmental Planning: An Integrated Multi-agent Approach BIBAFull-Text 119-129
      Dino Borri; Domenico Camarda; Anna De Liddo
    Mobility infrastructure planning is an increasingly crucial aspect of environmental planning, essential to boost regional economies and social relations, as well as critical for environmental impacts involved.
       Structuring inherently complex issues and problems is a major challenge of mobility planning. Today, therefore, a major issue is the setting up of system architectures that take into account the impacts of the mobility system on environmental and social quality.
       A multi-agent approach is seen as useful to let local stakeholders interact, meanwhile learning from each others' attitudes and cognitions. The present paper deals with the building up of an IT-based multi-agent platform in public interaction forums, particularly envisioning alternative mobility scenarios in the plan of the Italian province of Foggia.
    Research on Mobile Agent Based Information Content-Sharing in Peer to Peer System BIBAFull-Text 130-139
      Shaozi Li; Changle Zhou; Huowang Chen
    This paper presents our recent research work on mobile-agent based information content sharing in peer to peer system. Our work focuses on how to share the text content and recommend information based on mobile agent. The prototype uses terminology derived from the ant colony metaphor, including nest -- a peer entity, and ant-- an autonomous agent. Two mobile agents are proposed to implement the content-based text retrieval and information recommendation effectively. These agents are then evaluated through implementations and analysis. The simulated results demonstrate the advantages of our approach in the P2P system, and its potential applications in complex electric commerce and distributed information sharing.
    Environmentally-Aware Security Enforcement (EASE) for Cooperative Design and Engineering BIBAFull-Text 140-148
      Larry Korba; Yuefei Xu; Ronggong Song; George Yee
    In cooperative design and engineering, work context has dramatic implications when it comes to building understanding and teams, and getting the work done. From an information security perspective, the context of operation for software or hardware can drive the expectations for security, and may indeed determine the levels of security policy that would be required for collaborative operation. There is a place in this domain for proactive, context-based security implementation. This paper describes a context-centric security enforcement system intended for cooperative design and engineering environments that we call: Environment-Aware Security Enforcement (EASE). We describe the application of this approach to an existing client-server, e-manufacturing application.
    Grid Workflow Scheduling Based on Task and Data Locations BIBAFull-Text 149-156
      Yujin Wu; Ning Gu; Yuwei Zong; Zhigang Ding; Shaohua Zhang; Quan Zhang
    Grid workflow systems provide mechanisms to execute complex tasks which consist of related sub tasks. Due to the intensive computing and data transferring in Grid workflows, the locations of tasks and data have great impact to the execution performance of Grid workflows. In this paper, we present a novel approach to search for optimal Grid workflow scheduling effectively. We model workflow execution with fetching input data and running tasks, and present a optimized scheduling searching algorithm based on simulated annealing, which can find neighborhood scheduling fast. The experimental results show that our approach is effective and scalable.
    The Construction Management Cooperated with Clients Using a Parametric Information Design Method BIBAFull-Text 157-165
      Koichi Aritomi; Ryosuke Shibasaki; Nobuyoshi Yabuki
    This paper presents a new construction management cooperated with clients using a parametric information design method for road construction. This method aims for re-designing and for managing to achieve the conformance of the completed form of roads to planned design with survey equipment. By using this method, we design a road with an information model that has alignments, profile and cross sections. The model can be changed according to the site condition in collaboration with the planning designer of the client. This method is able to manage the conformance of completed form accurately because the information model is precise. Furthermore, the file size is so small that the survey equipment can store the data, and it is easy to re-design the plan. Therefore, we can use the survey equipment easily for the conformance management of completed form accurately and to re-design a plan by using CAD quickly. The management by this method has been found to be efficient and accurate.
    Theoretical Foundations for Knowledge-Based Conceptual Design of Complex Systems BIBAFull-Text 166-185
      Heriberto Maury Ramírez; Carles Riba Romeva
    The theoretical foundations that were developed and validated in a research work in order to the conceptual design systematizing of complex systems or processes, are presented in this paper. From the earliest design stages, two approaches of concurrent engineering, the Initial Specification and Conceptual Design, were integrated, the design for functionality (DFF) and design for environment (DFE). The obtained results are significant and novelty, because they determined the formal and heuristic required knowledge to the conceptual design systematizing. On the other hand, this work defined the nature and architecture of the required prototype software. The proposed foundations were validated on the conceptual design cases of the bulk solids handling and primary processing continuous system due to the obtained solutions with prescribed methodology were satisfactory, it was verified that the development foundations are rights.
    Public Digital Collaboration in Planning BIBAFull-Text 186-193
      Stefanie Dühr; Nada Bates-Brkljac; John Counsell
    It is becoming increasingly important to European democratic governments to increase public participation. One of the areas that gives rise to significant public dissatisfaction and feelings of dis-empowerment is that of environmental planning. Environmental planning is a diverse, complex and difficult process requiring consideration of wide ranging issues that include: urban function and form; cost and benefit; appearance and experience; and allocation and provision. The process is costly and so at any late stage difficult to deflect. This is not assisted by complex and even conflicting interpretations of the legislation. With broadening web access government bodies at various levels (national, regional, and city) are now turning their attention to web based approaches to easing access and empowering public involvement and debate on the issues. It is argued that replication on the web of existing plan and cartographic-based approaches to planning will tend to perpetuate the requirement for trained interpretation, thereby excluding the general public. More effective tools are required for collaborative citizen based examination and development of alternative proposals. This paper describes the basis for the coming three years of research in the Virtual Environmental Planning System (VEPS) project. VEPS proposes a new open standard web approach to enable citizens to view, analyse, interact with and respond to proposed changes, to collaborate and comment together and pose and test their own alternative solutions. This approach it is argued needs to be based on an interactive three-dimensional virtual reality visualisation that allows the viewer to experience the highly complex information without need for training, 'because they can see and experience what the visual impacts of the planned development will be and can see the environmental impact in the associated model'.

      Yongjoo Cho; Kyoung Shin Park; Soyon Park; Hyungtae Moon
    Digital Koguryo is a virtual reality reconstruction of the Koguryo mural tumulus called Anak No. 3. It was designed to help young children learn the cultural background and life style of the ancient Koguryo. This virtual environment brings the life aspects of the Koguryo culture to the users through a rich, interactive learning environment. In this paper, we present the collaborative design process among geographically distributed and multidisciplinary researchers, who worked to construct the Digital Koguryo project. We will also discuss design issues and lessons learned from this collaborative work.
    A Cooperative System Environment for Design, Construction and Maintenance of Bridges BIBAFull-Text 202-209
      Nobuyoshi Yabuki; Tomoaki Shitani; Hiroki Machinaka
    This paper proposes a new cooperative system environment for design, construction and maintenance of civil structures, especially bridges. We identified seven tools required to improve the productivity of design, construction and maintenance of bridges. They are product models, visualization system, communication tool, task systems with agents, database system, radio frequency identification (RFID) tags, and data reuse facility. These tools are to be integrated and used by owners, design consultants, contractors, manufacturers, etc., who can exchange and share structural, construction and inspection data, information and knowledge with this system.
    A Concurrent Approach to Design of Reconfigurable Machine Tools to Process Bamboo BIBAKFull-Text 210-217
      Carles Riba Romeva; Roberto Pérez; A. Jorge L. Sánchez; María D. Domínguez; Joaquín Aca; G. Arturo Molina
    Today, manufacturing systems must compete in increasingly diverse and demanding markets. Customers demand quick response to their needs, and products have shorter life cycles than ever before. In response to this context, the next generation of machine tools should be reconfigurable and intelligent. Reconfigurability allows for the reduction of machine design lead time, machine set-up and ramp-up time. This paper shows the development of an approach to concurrent design of reconfigurable machine tools to process bamboo, based on a concurrent design reference model to Reconfigurable Machine Tool development. In response, a methodology for the development of this type of machine tools is outlined.
    Keywords: Reconfigurability; Concurrent Design; Machine Tool; Bamboo
    Model for an Integrated Analysis of a Building's Life Cycle BIBAFull-Text 218-226
      Edmundas Kazimieras Zavadskas; Arturas Kaklauskas; Algirdas Andruskevicius; Povilas Vainiunas; Nerija Banaitiene
    In order to design and realize a high-quality project, it is necessary to take care of its efficiency from the brief stage to the end of its service life. The entire process should be planned and executed with consideration of the goals aspired to by the participating interested parties and the micro and macro environmental levels. In order to realize the above purposes an original Model of an Integrated Analysis of a Building's Life Cycle was developed by the authors to enable users and the parties involved in the project to analyze a building's life cycle, as well as to be able to see its micro and macro environments as one in tegrated entity. To achieve the above-mentioned aims new multiple criteria analysis methods and a Multiple Criteria Decision Support System for Building's Life Cycle were developed.
    Cooperative Shared Learning Objects in an Intelligent Web-Based Tutoring System Environment BIBAFull-Text 227-234
      Sylvia B. Encheva; Sharil Tumin
    This paper focuses on an intelligent Web-based tutorial system composed of reusable learning objects (LOs). Reusable LOs lay down the foundation for a large scale collaboration among educational organizations. LOs developed at different organizations can be used by other organizations thus providing high quality courses to all students. Expert instructors at each organization maintain a repository of LOs. For organizations owning LOs an audit trail for each LO can be easily gathered for billing purposes.
    Cooperative Integrated Web-Based Negotiation and Decision Support System for Real Estate BIBAFull-Text 235-242
      Arturas Kaklauskas; Edmundas Kazimieras Zavadskas; Algirdas Andruskevicius
    Construction and the real estate sectors have low efficiency and high fragmentation compared to other branches of the building industry. Scientists, practitioners and politicians from various countries input much attention, effort and time to eliminate drawbacks such as efficiency and fragmentation. Currently construction and real estate are characterized by the intensive creation and use of information, knowledge and automation (software, knowledge and decision support systems, neural networks, etc.) applications. It is commonly agreed that a better integration of information, knowledge and automation applications would significantly speed up construction and real estate sector processes, improve the value of decisions made and decrease the overall cost of a building's life cycle. The authors' objective in integrating decision support with knowledge systems is to improve the quality and efficiency of decision support systems. In order to demonstrate the integration decision support and knowledge systems a Cooperative Integrated Web-based Negotiation Decision Support System for Real Estate will be considered as an example.
    A Directed Evolution Modularity Framework for Design of Reconfigurable Machine Tools BIBAFull-Text 243-252
      Horacio Ahuett; Joaquín Aca; Arturo Molina
    Reconfigurable machine tools (RMT) have emerged as a potential solution to meet the demand for rapid adaptation in the next generation manufacturing systems. While a significant amount of research in RMT design is available, formal design methodologies are still under development. In previous work, a modularity framework technique for the development of RMT modules was outlined. The technique focused on module functionality and constructability. While in general these characteristics are critical for the survival of any product, specific characteristics of RMT were not easily addressed by the proposed methodology. In particular, convertibility, in the form of upgradeability and adaptability, was not addressed. This article presents an enhanced modularity framework that takes into consideration the intended evolution lines of the reconfigurable machine tool. The basic principles are outlined and applied to the design of a machine tool for metal working. Recommendations for future enhancements to the framework are made, in particular, the possibility of developing a convertibility index to facilitate evaluation of candidate designs is discussed.
    Study of the Intelligent Turning Machining Method Based on Geometrical Feature Recognition BIBAFull-Text 253-262
      Guofeng Qin; Qiyan Li
    Feature recognition is a key technology of the automatic intelligent turning machining method. This paper provides an intelligent turning machining method based on geometrical feature recognition, including putting up viewpoint, direction and cylindrical co-ordinate. For real-loops and unreal-loops in projection, an algorithm is taken forward to recognize the straight faces, turning circle (cone, frustum and cylinder) and slot, and creates a relationship functions among all the loops, determine the machinable turning cutting regions respectively according to the relationship functions. The study resolves the machinable problem in design stage, a method is supported to cooperative design and decreases the cost and save time. a hierarchy architecture of the center controller is constructed including integration process planning.
