Assembly Line Balancing Optimization

Semiconductor manufacturing processes are among the most complicated processes to manage. In this paper, we are interested in a problem of batching and scheduling in a diffusion area of ATMEL Rousset in France. This area contains a large number of lots to be processed and complex constraints to be satisfied. We present a decision-support system we implemented for the diffusion zone of ATMEL. The goal is to optimize batching and scheduling decisions at the diffusion area by developing fast and efficient solving procedures that optimize different performance measures while taking into account complex constraints. These procedures have been embedded in a decision-support system named batch optimization solver (BOS) that helps users at various decision levels. A prototype of BOS is currently being tested in the diffusion area of ATMEL.
