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...
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...
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,...
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...
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...
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...
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...
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...
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...
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...
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...
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...
This paper presents the XWiki Concerto system, the P2P version of the XWiki server. This system is based on replicating wiki pages on a network of wiki servers. The approach, based on the Woot algorithm, has been designed to be scalable, to support the dynamic aspect of P2P networks and network partitions. These characteristics make our system capable of supporting disconnected edition and sub-groups,...
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...
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...
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...
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,...
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...
In this work, we present a Collaboration Infrastructure Reference Architecture needed to enable the product development process collaboration that has become a common practice between different departments and companies in the context of an Extended Enterprise. Also, a methodology to model the required workflows is presented in order to coordinate the product lifecycle collaboration activities focusing...
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...
