摘要/Abstract

摘要： 回收品品质下降是一个客观事实,企业为了在成本支付和产品可靠性之间达成均衡,往往需要设置一个回收品可靠性阈值。本文考察电子产品的订购、到达、销售、回收、剔除过程,以新产品订购成本、新旧产品库存持有成本、产品回收成本、回收品检测清洁成本、短缺成本、抛弃成本和潜在风险成本为目标函数,获得“可靠性阈值—补货策略”的近优解。企业案例仿真结果表明,(s,S)补货策略优于(s,Q)补货策略;敏感性分析表明,新产品单位变动成本、新旧产品单位库存成本对企业成本影响较大;基于分析结果,为企业管理决策提出了参考意见。

Abstract: The reliability of product will gradually decline during the process of recycling. In order to gain a balance between cost and reliability, enterprises should set a reliability threshold. This paper observes the circulation of newly electronic items and returned items, sums up the ordering cost, holding cost, recycled cost, check cost, shortage cost, disposal cost and reliability risk cost, and gains an approximate solution about reliability threshold and acquisition. Data from an enterprise proves that, (s,S) acquisition policy is more economical than that of (s,Q). Sensitivity analysis shows that, unit newly item acquisition cost and unit holding cost work on the total cost. According to those analyses, this paper gives some suggestions to the enterprise.
