Research on semiconductor wafer fabrication's hot lots problem

In this paper the hot lots problem on semiconductor wafer fabrication is studied. Corresponding mathematical model whose object is to minimize the total cost of produce and transport is made. The method based on Binary Particle Swarm Optimization algorithm is proposed to solve this problem. The detailed realization of the method is illustrated, and an example is presented, the simulation results compared to solved by lingo software proves that the BPSO method is effective and stable.
