Artificial immune system is a new developing intelligent system based on the principles of the natural immune system. An immune algorithm is developed for job-shop schedule problem based on the clonal selection principle of the natural immune system.Using the strong search ability of immune algorithm can find the global optimal.By using the immune operations such as clone,hypermutation and suppression.it can improve the convergence rate and the diversity of population,and effectively solve the problems of population prematurity and slow convergence rate in genetic algorithm.Simulation result shows that the proposed immune algorithm is better in finding global optimal and convergent rate when comparing with the improved genetic algorithm.
