SOLVING THE MULTI-OBJECTIVE MIXED MODEL ASSEMBLY LINE PROBLEM USING A FUZZY MULTI-OBJECTIVE LINEAR PROGRAM

摘要

This paper develops a fuzzy multi-objective linear program (FMOLP) model for solving the multi-objective mixed model assembly line problem. In practice, vagueness and imprecision of the goals, constraints and parameters in this problem make the decision-making complicated. The proposed model attempts to simultaneously minimize total utility work cost, total production rate variation cost, and total setup cost. In this paper, an asymmetric fuzzy-decision making technique is applied to enable the decision-maker to assign different weights to various criteria in a real industrial environment. The model is explained by an illustrative example.
