Abstract
This paper presents a genetic algorithm for determining the rules for scrapping small lots in a semiconductor fab. Small lots are lots which carry less than 25 wafers due to yield problem. Simulation results show that the proposed approach can increase contribution margin up to 24% in the case of low yield and high average selling price.
