Abstract: AHP and fuzzy comprehensive evaluation are combined to work out a new method, which is used in the choice of optimal design and optimization of overall performance. So an applied programing system is developed. Due to the combination of the AHP and fuzzy comprehensive evaluation on the basis of opinions of experts and users, the demonstration results of the design together with the optimal selection could be satisfactory to the experience of experts and the expectation of users. This system has a good performance and a friendly interface. It can be widely adoped in the field of design option selection and in the management system for economice and social purpose. In the paper, ship overall performance is exemplfied as to discuss the method and the attributes of the program as well as how to use the program.
