英文摘要：

In order to solve the problem of test selection for complex system, a method of test selection was proposed based on the enhanced clonal selection algorithm. Aiming at the characteristics of test selection, the basic clonal selection algorithm （BCSA） was improved as follows： the use of binarycoding method for antibody encoding, the selection of additive piecewise function form for constructing affinity function construction, the application of chaos search method in the population initialization, and the introduction of antibody suppression of immune network into BCSA for antibody population pretreatment. Finally, simulation experiments on a practical system were carried out to verify the algorithm. The experimental results indicate that the proposed algorithm is characterized by high search efficiency and strong abilities of local ＆ global search, thereby dealing well with the test selection optimization for the testability design of complex system.
