Abstract: A delaminating evaluation method is suggested in this paper. The demands of social de-velopment upon every aspect of thermodynamic system is considered. As the first layer, and the specific evaluation indexes as the second one. By combining these two with the comprehensive fuzzy evaluation method, the subjection degree of fuzzy calculation shows the evaluation results. This paper proves the feasibility and rationality of the method through practical examples in prac-tice as well.

Key words: thermodynamic system, method, fuzzy mathematics, comprehensive evaluation, economy, circumstance
