Abstract

The process planning of a product represents in the manufacturing industry a major element that determines the level of economic performance of the company. The development and evaluation of process planning during the industrialization phase of a product can cause problems of quality, cost or manufacturing time. Therefore, process planning needs to be evaluated early, during the design phase. The aim of this article is to propose to a manufacturing company a hybrid approach of multicriterion decision support, allowing evaluating the concepts proposed by the designer to choose the best concept having the best industrial performance indicators, and to take into account the opinions of experts from different departments of the company. The multicriterion choice is made by the hybridization of the ROC method and the PROMETHEE method, and the decision criteria are indicators that express the performance of a process planning. Then, to illustrate the capacity of the model, a case study of a product is presented.
