Isi artikel

We consider capacity and production planning in hybrid production systems with two types of production channels, a manufacturing facility that produces new products and a remanufacturing facility that produces remanufactured products by reprocessing end-of-use/life products. The integrated problem is to determine capacity requirements and production quantities at both facilities to satisfy the demands over a given planning horizon. The objective is to minimize the total cost, i.e. the sum of shutdown, production (setup and operation), inventory holding and subcontracting costs. In particular, we consider the budget constraint that restricts the cost required to change manufacturing and remanufacturing capacities over the planning horizon. A mixed integer programming model is developed to represent the integrated problem mathematically. Then, due to the problem complexity, we suggest a linear programming relaxation based heuristic. Computational experiments were done on various test instances, and the test results are reported.
