  • Abstract In this research, we use the medium-and-small-sized manufacturer of TFT-LCD panels in Taiwan as our case studies. Because it takes 30 to 45 day even 60 days for the process making the “Raw Material” become “Products” for delivery. In such process, it is necessary to pass through the course from the supply of “Raw Material Supplier”, the production of “Manufacturing Dept.” to shipment. Therefore, it takes much more time than the course from order-making to delivery. 
    Most of manufacturers have two following response methods: One is to increase the inventory of “Raw Material” and the other is to raise the market demand forecast for production, however, both of which will cause the backlog of corporate cash capitals and reduce the turnover rate of corporate working capitals, resulting in indirect proportion of invested capitals to operating incomes. Therefore, how to reduce the holding cost of “Raw Material” and the carrying cost of “WIP (Work in Process)” is more important than how to enhance the manufacturing technology.
    This research targets at the TFT-LCD industry, which process can be divided into three following parts: For the Array, it is a fundamental processing of “Glass Substrate”; For the Cell, we process and combine “TFT Array Substrate” and “CF (Color Filter)” to turn into “cells”; For the Module, it is the module assembly with a customized specification and the packing of finished goods. 
    With “Case Research”, we study the reason for the inventory inaccuracy and also evaluate if such reason is existed. For the formation of such reasons, one is a visible reason that is provided by the vendor and also has been existed in their businesses. The other is a hypothetical reason that is provided by the researcher through his/her understanding of such corporate operation process and the application of theoretical learning. And based on the “Hazard Rate” and the “Survival Function” of “Event History Analysis” for reason determination this research makes the evaluation and the analysis to further provide a definite and reliable basis to reverse the presumed reason or to support the existence of new hypothesized reason. This research also makes use of the credible reason causing the inventory inaccuracy to discuss with the vendor and to provide an applicable improvement project.
