✦ Synopsis
The critical issues of memory chip manufacturing management are the fluctuation of manufacturing yield rates and demand quantity. To cope with. these problems generated by such uncertainty, this paper deals with two types of advanced production-inventory management system of memory chip fabrication, which consist of yield estimation, ropaldng operation of inferior goods and adjustment procedure of production quantities based on the production quantity planning procedure with in-process buffer. Quantitative characteristics of the proposed systems are investigated through simulation experiments and comparison analysis between current and proposed systems is performed to clarify their relevancy.
