【 摘 要 】

Since the descriptions and judgements on weapon systems are usually linguistic and fuzzy, it is more realistic to evaluate weapon systems in the framework of fuzzy sets theory. In this paper, a new method to evaluate the best main battle tank is proposed. It can be seen that the proposed method is more efficient due to the fact that, by canonical representation of arithmetic operation on fuzzy numbers, simple arithmetic operations on crisp numbers are used, instead of complicated fuzzy numbers operations. In addition, the final scores of each alternative can be represented as crisp numbers. As a result, the order of alternatives can be determined without the procedure of ranking fuzzy numbers. Finally, a numerical example to evaluate the best main battle tanks is used to illustrate the efficiency of the proposed method.
