中文摘要 | 本研究針對流通業庫存管理中兩種最重要的特性: 需求不確定性、及易腐壞物品 (例如各類鮮果、肉類、乳品等 ) 效用之考量,應用模糊集合論的方法來探討存貨管理之批 量政策。本研究選擇了七種常用的批量方法,並將其中物品之不確定需求和品質效用「模糊 模式化」。 在物流業配銷需求規劃 (DRP) 環境下,本研究以七種需求模式、三種成本結構 、五種品質效用遞減模式,及「總成本」與「品質效用」兩種績效評量指標,針對七種批量 方法進行模擬實驗,並以桃園地區某低溫物流公司提供之實際資料進行實證。研究結果顯示 ,在不同的模擬環境下、各種批量方法之績效評量有顯著差異。本文分別就兩種評量指標、 不同參數設定之 DRP 架構,建議最佳之存貨管理政策。 |
英文摘要 | This research deals with lot-sizing problems in which the fuzzy set theory is used to model two of the most important properties of inventory management in logistics enterprises: the uncertain demand and qulity utilization of perishable goods (e.g., vegetables, fruits, meat, dairy products, etc.). Seven commonly used and well-known lot-sizing methods are selected from the literature and are modified to incorporate demand uncertainty and quality utilization through fuzzy modeling. The seven models are compared using simulation under distribution requirements planning (DRP) environment that resembles the multi-echelon distribution structure in logistics enterprises. Several key parameters of the DRP system are taken into account in the simulation study, which include demand patterns, cost coefficients and utilization functions. The performance measures of this study are total operating cost and quality utility upon demand. For validation and application purposes, actual data provided by a logistics company is used to drive the simulation, and the results are presented. Intensive computational results show that the performances of the seven models are significantly differenct under a variety of simulation environments. Hence, the optimal inventory policy is suggested in accordance with different system environments and performance measures. |
