چکیده
A modular simulation system (MSS) for the scheduling of semiconductor wafer fabrication facilities (fabs) is discussed. Firstly, the general structure model (GSM) for modeling a semiconductor wafer fab, composed of a configurable definition layer, a physical layer, a process information layer and a scheduling layer, is proposed. Secondly, a data-based dynamic modeling method is given. Thirdly, the architecture of MSS, composed of data layer, module layer and simulation layer, is presented. Finally, a case study is used to demonstrate the effectiveness of MSS. Streszczenie. Zaprezentowano Isystem symulacji modularnej do planowania produkcji w przemyśle półprzewodnikowym.

The static and analytic scheduling approach is very difficult to follow and is not always applicable in real-time. Most of the scheduling algorithms are designed to be established in offline environment. However, we are challenged with three characteristics in real cases: First, problem data of jobs are not known in advance. Second, most of the shop’s parameters tend to be stochastic. Third, th...
