Agent-Based Product Configuration: towards Generalized Consensus Seeking

This paper will present an evolution of a fuzzy agent based platform which performed products configuration. As a first step, we used the notion of consensus to establish robust results at the end of the configuration process. We implemented the concept of generalized consensus which implied the consideration of consensuses from the beginning, in this way robust data are treated during the entire process and the final result enables the designer to distinguish the robust components and flexible ones in a set of configurations.Comment: 8 pages, 8 figures, 5 table

Multi-domain product modelling: from requirements to cad and simulation tools.

Today, in a very competitive industrial context, different companies have difficulties to respect delays in design and manufacturing of multi-domain product. These difficulties are most of time due to the non respect of requirements defined at the beginning of the project development, during the Function Performance Specifications phase. Furthermore, an important problem during multi-domain products design and development process is the communication between experts of different domains. To answer to this problem, the authors propose in this paper to describe and analyze this problematic through a meta-model. They focus only on mecatronic product. From the proposed meta-model analysis, they develop two possible links between both mechanical and electronic domains in a model: (1) between models and (2) between analysis tools of different domains. The application of this model to a concrete example shows that we can link all the main common data of a product design and development to the modeling and simulation tools of different domains

Tool based supporting collaborative design from specification development to CAD modelling

International audienceManagement of dynamic information interdependencies and as well as management of multiple perspectives from specification development to conceptual design, as well as from conceptual design to detailed design are critical elements of collaborative and distributed design. Supporting collaborative design with computer technology is a strategy to enhance the ability of actors to interact with each other and with computational resources during different phases of product design and development. However, many observations from the industry and research support the evidence that both specification development phase and conceptual design are poorly supported by collaborative tools. Furthermore, though CAD tools support detail design, it is imperative to develop new collaborative design tools or renovate traditional standalone CAD systems by making it collaborative-native. Consequently, the first goal of this paper is to propose the development of collaborative tools related to the conceptual design. The second goal is the development of a mechanism for communication between the developed collaborative conceptual design tools and actually CAD tools. The mechanism and architecture of the developed tool for collaborative conceptual design is presented. A design problem illustrates the concepts discussed in the paper

An intelligent system for the interactions analysis in a collaborative design process

International audienceDuring the collaborative design process, the cooperation between actors is variable and fluctuating. This paper proposes an agent-absed system for analyzing those interactions. The system reacts graphically according to the verbal exchanges between various actors. From this point of view, the system makes it possible to follow the privileged relations in a group and to make simulation of the selforganization inside this group. Our objectives are to provide each agent with some capacities of interpretation of the exchanges. In that case, we could be able to refine the deductions on the interactions between actors, by adjusting the functions of interpretations

Intelligent agents for feature modelling in computer aided design

CAD modelling can be referred to as the process of generating an integrated multiple view model as a representation of multiple views of engineering design. In many situations, a change in the model of one view may conflict with the models of other views. In such situations, the model of some views needs to be adapted in order to make all models consistent. Thus, CAD models should be capable of adapting themselves to new situations. Recently, agent based technologies have been considered in order to increase both knowledge level and intelligence of real and virtual objects. The contribution of this paper consists in introducing the intelligent agents in intelligent CAD modelling. The proposed agents are elementary geometrical and topological objects. They incorporate the functions of observation, decision and action, and possess their own knowledge. Agents have the capacity of communication and inference based on the feature grammars. They are modelled as bio-dynamic objects that enjoy the properties of fusion, division and multiplication. Being aware of the context, the proposed agents interact to form potential regional transitory communities, called regions. Being aware of their belonging in a region, agents interact by generating virtual links (virtual extensions). These virtual links produce: (a) fusion of agents, (b) division of agents and c) multiplication of agents. The emerged agents interact with the other agents in a region to recognize each other and to form specific sub-communities, called intelligent features. From a CAD software development point of view, this paper advocates the idea of a new phase of CAD system development based on the agent-oriented programming (AOP) paradigm
