Victor Taratoukhine, Kamal Bechkoum INTELLIGENT DETECTION OF MISMATCHES IN DISTRIBUTED DESIGN
Design engineers are still sceptical about the ability (or inability) of current intelligent de-sign-support systems. For example, even when endowed with some sort of intelligent behaviour, existing CAD/CAM systems cannot handle several types of inconsistencies that may occur during the design phase.
Mainly due to the complexity of the design process existing solutions tend to approach the problem from a very specific angle. For example, commercial systems such as CATIA (Dassault Systems) and I-DEAS (SDRC) do provide assembly mismatch analysis, but their approaches are more focussed on the analysis of tolerances.
Moreover, even when the proposed approach is successful in detecting a design anomaly rarely does it suggest a satisfactory way to resolve the problem.
In most of the previous work all the design knowledge is centralised into one unit: the knowledge base. The centralisation of knowledge coupled with the absence of a negotiation mechanism (between all parties involved in the design) makes the process of predicting the impact of any modification an (almost) impossible task [1].
We re-inforce here the view that a multi-agent approach can tackle many of the problems posed by the centralisation of knowledge into a single Knowledge Base. A new multi-agent framework is proposed [2]. We represent conceptual framework as community of calendar and reactive agents. In our case design agent (D-agent) is a reactive agent, which negotiate with other D-agents using design’ schedule (assembly sequence) band scheduling preferences generating control agent (C-agent).
This multi-agent framework will be at the heart of an intelligent distributed mismatch control system (IDMCS) that aims at ensuring that the overall design is consistent and acceptable to all.
