The Inventory Models of Fashion Products with Setup Cost And Quality Level.

[[abstract]]傳統存貨模型將存貨策略視為不可控制的常數，如商品的品質、設置成本、與前置時間等，由於及時(Just in time ,JIT)的生產系統的經驗，可以藉由投資資金來縮短前置時間、降低設置成本與提高品質水準，以達到減少全年期望總成本為目的，因此本研究主要是探討需求量服從羅吉斯分配下的前提下，考慮可控制的前置時間內，允許缺貨且缺貨發生時考慮部分欠撥、部分銷售損失與生產過程不完備混合的存貨系統，提出一個已訂購數量Q、請購點r、設置成本A、品質水準θ與前置時間L等五個決策變數的存貨模型，並以計量方法推導出全年期望總成本為最小的問題最適解。[[abstract]]Strategies are regarded as uncontrollable constants, like the quality level, setup cost, and lead time, in traditional inventory models. Based on the experience of the Jus-in-time production system, it is likely that investment funds could be used to shorten the lead time, reduce the setup cost and lift the high-quality level. The ultimate aim is to reduce total expected annual cost. The accent of this research is on the discussion of the demand that obeys logistic distribution under the premise that the lead time is under control. In addition, we also assume that the condition of shortages is accepted. Moreover, the total amount of stockout is considered a mixture of backorders and lost sales during the stockout period. We propose an inventory model that includes five decision variables--- order quantity, reorder point, setup cost, quality level and lead time---and we utilize the numerical examples to illustrate the effects of inventory systems associated with investing capital in changing the values of parameters
