Abstract: The problem of task schedule is an NP problem. The algorithm about this problem is an important research direction. Through researching and analyzing the model of task scheduling and the immune algorithms existed, the paper presents a task scheduling algorithm based on real-coded immune algorithm. It discusses the style of coding, the generation and update of stocks, the update of memory cells and the value of parameters, and explores the functions of affinity and concentration degree. This algorithm is realized with the software of the VC++, and through the example comparative analysis, this algorithm is proven validity and feasibility.
