Application of ant colony optimization in preventive software maintenance policy

This paper studied preventive software maintenance policy based on ant colony algorithm. The entire system was divided into several subsystems and each subsystem has 4 kinds of maintenance policies with different maintenance cost. This model can obtain optimal preventive maintenance policy of each subsystem which guarantees excellent software system reliability with relatively lower costs. An example was presented to testify the effectiveness of the method we designed. The results show that the model we presented is efficient and effective.
