摘要

近年來產品生命週期越來越短，導致晶圓產業需求日益劇增，也因此相同產業之間的競爭越來越激烈，供應商為了避免發生供不應求或延遲出貨所導致顧客對企業的不信任，因此存貨管理便是供應鏈管理中十分重要的一環，然而過多的庫存會導致企業資金的積壓，資金運用缺乏彈性無法用於其他投資，過少的庫存亦會導致無法如期供貨或產線停工待料等問題，因此為了具有競爭力，公司必須有效地管理和控制其材料。
然而，單單只有良好的庫存管控能力是不夠的，若是原物料的用量並沒有做到良好的監控，亦會造成不必要的浪費，也因為浪費進而導致庫存水位飄浮不定，因此擁有良好的物料監控模式也是十分重要的，而液體材料的用量監控企業往往依賴於自動化機台的感應器，沒有感應器的情況下，企業便無從得知用量狀況並設立標準，也無法利用標準來預測庫存，因此，本論文探討自動化機台的液體計量模式，利用計量模式探討物料的標準用量，以利企業用於即時物料監控；此外，有了用料標準後，便可以利用標準來推估庫存水位，避免不必要的堆積，因此，本研究利用實際案例分析不同模式下的庫存預測精準度，分別在有標準用量、無標準用量和錯誤的標準用量下，顯示物料管理與庫存管理間的相互影響與本研究模式的實用性，分析統整後結果顯示本論文確實能達到物料即時監控與降低整體庫存量之效果。

In recent years, most of the electronic goods product life cycle is getting shorter and shorter, leading to an increasing demand in wafer related products. To avoid shortages or delayed shipments of the parts, a smooth supply chain material inventory management becomes critical. In order to be competitive, it is indispensable for companies to manage and control their materials efficiently. In the wafer industry, in order to reduce waste, the management of high cost liquid material is critical. Enterprises often rely on the sensors of the automated machine to monitor the usage of liquid materials. The company has no way to know or calculate the liquid material usage, Unable to set standard, nor the use of standard to predict the material requirements. Therefore, this study discusses the liquid measurement model of an automated machine tool and uses liquid measurement model to explore the standard usage of liquid materials so that the X Company can use them for instant material monitoring. Further, the liquid material standard can be used to estimate the inventory levels to avoid unnecessary accumulation. This study uses a real case study to analyze the accuracy of inventory forecasting under three different situations: non-standard dosages, standard dosages, and incorrect standard dosages. These analyses are performed to show the interactions between the actual liquid material usage and the practicability of this research model. The results show that the model we developed can indeed achieve the effect of real-time material monitoring and reduce the overall inventory.
