研究了考虑回收率依赖于回收品价格,并带有废弃处理的制造和再制造混合系统的(1,R)和(M,1)EPQ模型.在模型中,采用新产品的制造和回收产品的再制造两种方式来满足客户的需要,回收产品部分用于再制造,其余作为废弃处理;总平均成本包括与回收产品、可销售产品有关的库存持有成本,与制造和再制造有关的生产成本和固定成本,与回收品及制造所需原材料的采购成本以及废弃处理成本.模型给出最优生产策略及总平均成本的表达式.算例验证了所建模型的计算方法,并分析了新引人决策变量p(回收产品单价占制造新产品所需原料价格的比例对总平均成本的变化率的影响.
(1, R) and (M, 1) EPQ models of hybrid systems for manufacturing and remanufacturing with recovery rates dependent on the prices of the recovered products and with disposal are studied. In the model, the products manufactured and recycled using new products Remanufacturing two ways to meet customer needs, recycle part of the product for remanufacturing and the rest as waste disposal; the total average cost includes inventory holding costs related to recycle products and salable products, and manufacturing and remanufacturing related Production cost and fixed cost, purchase cost of recovered materials and manufacturing raw materials, and disposal cost.The model gives the expression of the optimal production strategy and the total average cost.The example verifies the calculation method of the model and analyzes The impact of the new introductory decision variable, p, on the rate of change of the total average cost, is the ratio of the unit price of the recovered product to the price of the raw material needed to make the new product.
