Experts's agreement support for distributed engineering Knowledge Modelling

Abstract

Knowledge sharing among partners in collaborative and concurrent engineering processes is becoming more critical for decision-making in Product Design Engineering (PDE) -- The approach presented in this article proposes a Fuzzy Logic (FL) based semi-automatic support for reaching agreements in the definition of variable’s domain under a Constraint Satisfaction Problem (CSP) modelling process -- A negotiation model is proposed, including suggestions about preferred domains for a variable that it is used for more than one expert -- Competence of the users involved in the negotiation is measured with a set of developed indexes -- A Fuzzy Inference System (FIS) is used to calculate user’s indexes and suggestions about the domain are made based on the proposed domains and competence index of the experts -- The proposal is included in a Multi-Agent System (MAS) for supporting distributed knowledge modelling
