Abstract
Following the development of semiconductor industry, the relationship between firms in supply chains is very complex. The performance of supply chains depends much on the integration of business processes, decision-making and information systems. The production planning of an enterprise thus is extended for cooperating with others. Moreover, there is a trend to integrate the whole semiconductor factories for achieving the mission of producing final products. This study will focus on wafer fabrication and probing process and will develop a collaborative production planning system.
Two core mechanisms are addressed in this thesis. The first is master scheduling system for the wafer fabrication. According to the throughput plan of the enterprise, we derive product mix with the considerations of the capacity limitation of each site, in order to suit the performance. Next, based on the estimated cycle time, we can predict the due date of each order that is an input data for the production planning system of probing process.
The production planning mechanism for the wafer probing factory aggregates planning results of wafer fabrication, such as predicted due date of each order, throughput target of each product type, capacity supply and capability constraints of every workstation. With this result, this thesis then assign job-order of each product type to the workstation and provide last setup configuration of machines.
In this study, the interaction between two nodes is discussed about B-shop setup changeover rate as a performance index. We developed a framework to integrate scheduling and planning processes and obtain better performance evaluation.
