Considering the remanufacturing system with complex features and multiple uncertainties under closed-loop supply chain environment,an optimization model of MC-oriented remanufacturing aggregate production planning (RAPP) was established.By using fuzzy set theory,a fuzzy liner programming method was adopted to change the uncertainty problem into an equivalent deterministic mass integer linear programming (MILP) problem.The remanufacturing aggregate production planning can not only maximize profits but also find the optimal purchasing size,the homemade parts size and products manufacturing size.An example was proposed to validate the actual effectiveness of the model in remanufacturing enterprises' production.The analysis on the influences of correlation factors on the total profits will contribute to remanufacturing enterprise management decision-makers to arrange corresponding RAPP to gain the optimal profit.
