Demand-Pull 补货模式之研究 研究生:袁国荣 指导教授:?荣贵 博士 国?交通大学工业工程与管?学系 摘要TOC demand-pull 与缓冲管?是观?相当?错的供应链解决方案.但因缺 乏严谨的的程序与方法?做好缓冲管?所需考虑的三要素,使得 TOC demand-pull 的应用变成黑盒子.许多学者与实务应用者也因此质疑 TOC demand-pull 观?的可?性,并对其使用效果优於目前广为使用方法也产生怀 疑,同时也造成将此方法电脑化应用的障碍.因此,本研究的目的在於提出? 严谨的缓冲管?法则与方法?强化 TOC demand-pull,同时修正 TOC 产出 天?元(Throughput Dollars-Days, TDD)/IDD 存货天?元(Inventory Dollars-Days, IDD)指标与提出 EVD(Exposure Dollars-Days, EVD)指标,使TOC demand-pull 在供应链管?的实务应用上?加完备,并能获得比现在广为使用的方法?为有 效. 本研究首先针对缓冲管?三要素做探讨,提出目标库存?决定法则与方 法、补货频?与补货??、缓冲监控程序与目标库存?调整准则.其次修正TOC 的TDD与IDD二个绩效指标并提出缺货EVD指标,以评估缺货机?与存货高 低,使其?适用於供应链缓冲绩效的评估,强化TOC 缓冲管?机制在供应链 管?的实务应用,最后为?证明此研究所提的观?、法则与方法是可?且有效 的,以一个实际个案?做验证. 关键字:限制??,缓冲区管?, TDD 产出天?元指标(Throughput Dollars-Days), IDD 存货天?元指标(Inventory Dollars-Days,), EVD 缺货指标(Exposure Dollars-Days, EVD). i Enhancement of TOC Demand-Pull Replenishment Student: Kuo-Jung Yuan Advisor: Dr. Rong-Kwei Li Department of Industrial Engineering and Management National Chiao Tung University ABSTRACT TOC buffer management and Demand-Pull replenishment is an outstanding and effective model critical to support the concept and knowledge of inventory management by conscientious processes and methods. Imperfection of perfectible discussion on the three key elements of buffer management would result in questionable Demand-Pull inventory system. Ineffectual and visible barriers of computerize in various practices. Furthermore, implementers would significantly suspect the practice of TOC demand-pull concept. Typically to meet perfectible practices of TOC demand-pull practice and implement it in supply chain management, this thesis proposes a heuristic buffer management methodology to enhance the Demand Pull replenishment and modify the buffer management performance index. Furthermore, consolidation of TOC Demand-Pull is practiced significantly and effectively in supply chain management. In connection with the probe for the three key elements of buffer management, the thesis provides critical rules of inventory decisions. Firstly, target rules are provided for inventory decision methods including replenishment frequency, replenishment quantity, the concept of monitoring window is proposed to detect the level of inventory and criterion of inventory adjustment. Secondly, propose the EVD and modify the TDD (Throughput Dollar-Days) and IDD (Inventory Dollars-Days, IDD) based on the Throughput Dollars-Days index proposed by Goldratt to measure the buffer management performance and to enhance the TOC buffer management model of perfectible practice. Finally, real cases are simulated to assess the performance enhancement through the proposed methodology. Key Words:TOC (Theory of Constraints) , Buffer management, TDD (Throughput Dollars-Days), IDD(Inventory Dollars-Days), EVD(Exposure Dollars-Days),Demand Pull Replenishment. ii 志谢终於毕业?,在此特别表达对恩师?荣贵教授最崇高的敬意,在这麽多? 的博士学习期间在学术研究上给我许多建议、指导与鼓?,协助我顺?完成漫 长博士学业.回首博士??,汲汲奔?於职场与课堂,夤夜苦?,?非恩师之 激?与关怀,实难以完成,由衷感谢恩师的悉心指导. 在课堂学习上特别要感谢沙永杰教授、锺淑馨教授与?庆恩教授的启发与 教导,获??多.而同窗好友?忠、黄俊?、廖士荣、赖庆?、韩慧?与张子 \,以及?文阳学长的热心帮忙,并此言谢. ?文审查要特别谢谢?渊源教授、沙永杰教授、?景尧教授与蔡志宏教授 对於审查时给予宝贵的修正建议,使本?文?加完善,也要感谢张盛鸿博士在 撰写?文与投稿上的协助. 回顾多少夜,与爱妻及三个心爱?儿在灯下,?少学生,或埋首书卷,或 振笔疾书,其间和?,亦为支持我完成学业之驱动?.此外,感谢爱妻的全? 支持与体?,让我得以全?以赴. 最后最重要的是谨将这分荣耀献给一生辛?的敬爱母亲. 袁国荣
