Mold Simulation Grid and Its Application for Optimization Problems

A four-layer simulation grid platform for optimization was proposed which includes simulation resources layer,supporting toolkits layer,schedule method layer and simulation applications layer. Function of each layer was introduced and related techniques were indicated. Based on developed generic algorithm,a grid algorithm was proposed for collaborative solving complex optimization problems on the platform by using the massive simulation resources. Example of gate location optimization was conducted on the platform by using the grid algorithm successfully. The results show that the grid platform is reasonable and the grid computational method has good accuracy and high efficiency.
