英文摘要：

For the permutation flow shop scheduling problem with transfer lags which aims to minimize makespan, an integer program model was established. The improved genetic algorithm with a new method of generating initial population, which is based on the study of classic genetic algorithm, is presented. The new method transforms the permutation flow shop scheduling problem with transfer lags into a two--machine permutation flow shop scheduling problem with transfer lags. A part of initial solutions consist of the solution of the transformed scheduling problem. The simulation experiments using the Taillard ＇ s instances show the presented algorithm is feasible and effective.
