Collaborative Decision-Making in Product Design : An Interactive Multiobjective Approach

Abstract EN

This paper presents a new procedure to solve multiobjective problems, where the objectives are distributed to various working groups and the decision process is centralized.

The approach is interactive and considers the preferences of the working groups.

It is based on two techniques: an interactive technique that solves multi-objective problems based on goal programming, and a technique called “linear physical programming” which considers the preferences of the working groups.

The approach generates Pareto-optimal solutions.

It guides the director in the determination of target values for the objective functions.

The approach was tested on two problems that present its capacity to generate Pareto-optimal solutions and to show the convergence to compromise solutions for all the working groups.
