We are interested in real time collaborative interactions within Collaborative Virtual Environments (CVE). This domain relies on the low latency offered by high speed networks. Participants of networked collaborative virtual environments can suffer from misunderstanding weird behavior of some objects of the virtual universe, especially when low level network troubles occur during a collaborative session. Our aim is to make such a virtual world easier to understand by using some graphic visualizations (dedicated 3D metaphors) in such a way that the users become aware of these problems and can go on working even during these troubles. In this paper we present how two independent mechanisms may be coupled together for a better management and awareness of network troubles while interacting within a networked collaborative virtual environment. The first mechanism is an awareness system that visualizes, through the use of special metaphors, the existence of a network trouble as strong delay or disconnection. The second mechanism is a virtual object migration system that allows the migration of an object from one site to another to ensure a non interrupted manipulation in case of network troubles.We will detail only this awareness system and we will show how it uses the migration system to allow users to go on interacting while network breakdowns occur.

This paper presents the first results of a research-partnership between Ecole Nationale Supérieure des Mines de St Etienne (G2I) and StMicroelectronics (Rousset France). We explain the results of a first stage of research works which aim at developing a method for the management of the evolution of information systems. Our current contribution consists in a domain-oriented enterprise modelling approach. We justify the structure of the meta-model proposed and we show its links with evolution management

To support open process networks and virtual enterprises, activities have to be coordinated not only within an organization, but also between organizations. This inter-organizational coordination of activities creates new requirements, not met by existing architectures. Therefore, a new coordination architecture based on web services is developed. It uses a homogeneous and dynamic composition of so called aspect-elements to support the interorganizational coordination of activities. The coordination architecture provides coordination autonomy and knowledge encapsulation and offers both process evolution and scalability. At the same time, the benefits provided by web services such as service autarchy, service extensibility, service integration and asynchronous service evolution are maintained.

Nowadays, people not only need to communicate, but also require to cooperate in order to achieve common goals. Thus, groupware applications are more complex, they have to satisfy new requirements of cooperation between people in many areas such as: organizations, industries or entertainment. Besides, due to the remarkable increment in the use of mobile devices and other technologies, groupware has found new environments to provide solutions and better services to end users. The Ayllu human cooperation model states that people must interact using well defined and structured protocols as rational cooperative agents do. This paper presents the Ayllu architecture, which is intended to develop groupware applications with a cooperative approach, called 5C paradigm; based on software agents that act as mediators between users working cooperatively. Cooperative services are constructed and executed by a mechanism called volatile group. Ayllu supports the execution of cooperative services, people can cooperate immersed in a pervasive environment, interact in an organized fashion, conform communities and pursue common objectives without concerning about their individual context.

The workflow map development for an organization is a highly complex process. Therefore, the workflow map should be tested and validated before it is implemented (into a WfMS). Most current workflow systems deal with this validation issue by using simulation modules that “execute” the model and examine the possible problems before it is truly “executed” and implemented. Although these simulation modules are very useful for the management team to detect problems in the business processes represented by the workflow, it would be advisable to find other more reliable methods. In this paper we propose a formal method based on Temporal Logic of Actions to formalize workflow maps (based on a communication modelling methodology).

In this paper the theory of Electronic Data Interchange (EDI) is applied to the safety case management domain in order to evaluate its benefits and to assess the potential issues which relate to data exchange within certain industry sectors. The work is undertaken to establish best practise and to examine successful techniques identified by other researches in the area of XML/EDI and to implement them in data transmission from a safety case management tool based on MS Visio to the Integrated Safety Case Development Environment (ISCaDE) residing on a Dynamic Object Oriented Requirements System (DOORS) database. Goal Structuring Notation (GSN) and its XML dialect Goal Structuring Mark-up Language (GSML) developed at the University of York is used as messaging specifications to represent the safety case model. Furthermore, these specifications are used to build EDI software to transport data across different safety packages.

We introduce an intelligent drivers’ model for traffic simulation in a small area including some intersections, which is formalized in a paraconsistent annotated logic program EVALPSN. The intelligent drivers’ model can infer drivers’ speed control actions such as “slow down” based on EVALPSN defeasible deontic reasoning and deal with minute speed change of cars in the simulation system.

Service processes play a more and more important part in modern economies. However, their design does not achieve the flexibility and efficiency known from ordinary business processes. Furthermore, their double identity of being process and product at the same time is not properly represented in present design methods. Therefore, a new method for the design and the support of inter-organizational service processes is introduced. It is based on so called perspectives for separating independently evolving parts of the service processes. Based on it, a component-oriented approach for process design is developed.

The maturity of infrastructures that support e-services allows organizations to incorporate Web services as part of their business processes. One prominent solution to manage, coordinate, and orchestrate Web services is the use of workflow technology. While workflow management systems architectures, language specifications, and workflow analysis techniques have been extensively studied there is a lack of tools and methods to assist process development. The purpose of our study is to present a framework to assist process analysts and designers in their task, allowing the creation of processes (Web processes and workflows) with a higher quality. The framework structures a comprehensive set of steps that drives the analysis and design of processes based on requirements gathered from communication with managers and experts.
