针对电厂设备维修方式难以定量选择的问题，提出了基于熵权和层次分析法的模糊综合评价方法。该方法将熵权与层次分析法相结合，克服了传统方法的主观性和盲目性。该方法将模式划分为由指标因素组成的层次，根据相应的矩阵计算主、客观权重，拟合出综合权重。最后根据评价原则，通过综合权重和判断矩阵确定维修模式。实例计算结果表明，该方法是有效可行的，能够对维修方式进行评价，为状态维修决策提供依据。
Aiming at the difficulty in selecting the maintenance mode for power plant equipment with ration, the fuzzy comprehensive evaluation method based on entropy weight and analytic hierarchy process (AHP) is suggested. It combines entropy weight with AHP for against the casualness and subjectivity in traditional method. With the method, the mode is divided into some layers composed of index factors, and then the subjective and the objective weights can be calculated to fit the comprehensive weights based up on the corresponding matrix. Finally with the principle of evaluation, the maintenance mode can be decided by the comprehensive weight and judgment matrix. The calculating result of applying the proposed method to the example demonstrates that the method is valid and feasible, and it is capable of evaluating the maintenance mode for supplying the gist for the condition maintenance decision.
