Abstract
In this article the main reasons why Infineon Technologies uses programming languages for optimization in its semiconductor manufacturing facilities are presented. Experiences from the past with optimization techniques for logistical problems in our fabs are discussed and our choice of programming languages for optimization is explained as a strategic decision. A closer look at the scheduling and routing problems as they appear in our semiconductor fabs shows that this choice was also practically enforced, since we encountered certain specific and severe difficulties when we tried to work with a commercial Algebraic Modeling Language (AML) and the accompanying solver suite at one of our basic optimzation problems, namely a specific routing problem requiring load minimization, load homogeneity and fair queueing. The possible gain of new developments in AMLs for modeling transparancy in our company is disputed and we conclude that the incorporation of Brownian network formulations into AMLs could possibly relieve our optimization programmers’ work.
