AnOptimization Decision Approach for the Bi-objective Production Routing Problem of Equipment Maintenance Material

In the supply support for equipment maintenance material, in consideration of the requirements of military users on the accuracy of material support in the context of precise support, two objectives are simultaneously optimized, i.e., to minimize the total cost, and to maximize the order accuracy. A novel bi-objective model is proposed for the problem. Then in the framework of ε-constraint method, a two-phase iterative heuristic and a fuzzy logic decision method are developed to generate a near-optimal Pareto solution set and to help decision makers select a preferred solution.The experimental results on randomly generated instances indicate that the proposed model and algorithm can be applied into bi-objective optimization problemeffectively, and exhibit extraordinary performance in solving different scales of instances.
