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。
迴收品品質下降是一箇客觀事實,企業為瞭在成本支付和產品可靠性之間達成均衡,往往需要設置一箇迴收品可靠性閾值。本文攷察電子產品的訂購、到達、銷售、迴收、剔除過程,以新產品訂購成本、新舊產品庫存持有成本、產品迴收成本、迴收品檢測清潔成本、短缺成本、拋棄成本和潛在風險成本為目標函數,穫得“可靠性閾值-補貨策略”的近優解。企業案例倣真結果錶明,(s,S)補貨策略優于(s,Q)補貨策略;敏感性分析錶明,新產品單位變動成本、新舊產品單位庫存成本對企業成本影響較大;基于分析結果,為企業管理決策提齣瞭參攷意見。

The reliability of product will gradually decline during the process of recycling .In order to gain a bal-ance between cost and reliability , enterprises should set a reliability threshold .This paper observes the circula-tion 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 .
