Multi-step Determination and Evaluation Engineering and Its Mathematical Model

Based on the principle of the combination of the qualitative and quantitative determination, a system structure and a mathematical model for determination and evaluation engineering combining both fuzzy and precision aspeds has been developed by using the theory of fuzzy set and the method of statistic analysis. The determination and evaluation tests have shown that the system structure and its mathematical model can correctly represent the real situation with noticeable efficiency and its computation is both simple and rapid.
