Production Planning in Remanufacturing Systems: Mathematical Model and Solution Algorithms
Remanufacturing, one of the most advanced product recovery options, processes used or end-of-life products with disassembly, reprocessing, and reassembly operations in such a way that their qualities are as good as new in terms of appearance, reliability, and performance. Among various issues in remanufacturing, we focus on production planning over a given planning horizon for the objective of maximizing the total profit, i.e., difference between the revenues and relevant costs. The main decisions are: (a) number of products to be disassembled and disposed in each period; (b) number of parts and components to be reprocessed and disposed in each period; (c) number of parts and components to be purchased in each period; and (d) number of products to be reassembled in each period. In particular, we extend the existing model by incorporating setup costs and times. A mixed integer programming model is developed to represent the problem. Then, due to the complexity of the problem, heuristic algorithms, based on the linear programming-based technique, are suggested in this paper. Computational experiments were done on various test problems, and the results are reported.
