[Abstract]:Comprehensive evaluation is a comprehensive understanding of things. Its research objects include the selection of index system, the calculation of weights, the selection of evaluation methods and the reliability analysis of evaluation results. After decades of development, more than 100 classical comprehensive evaluation models have been developed. Their theoretical basis has been relatively mature, but the evaluation method has been optimized and improved. The objective calculation of weights and the reasonable selection of evaluation methods still have some shortcomings. According to the main problems existing in the current comprehensive evaluation method, this paper has done the following research work: 1. Based on the analysis of Analytic hierarchy process (AHP), Fuzzy Comprehensive Evaluation (FCE), data Envelopment Analysis (DEA), Grey Comprehensive Evaluation (GRAP) and artificial Neural Network Evaluation (ANN). The advantages and disadvantages, application scope and module design of each method are summarized in detail. 2. The analytic hierarchy process is improved. In the traditional analytic hierarchy process (AHP) judgment matrix, experts only consider the most likely value of matrix element 偽 ij, and ignore the fuzziness and subjectivity of human judgment on things. Some scholars have improved the construction of judgment matrix, but the improved model is not widely representative. In this paper, the AHP method is improved from two aspects: (1) A more general improved model is proved by statistical analysis, a judgment function is constructed, and the improved model is discussed. A more reasonable method of constructing judgment matrix is obtained. (2) several new weight calculation methods are introduced, and the complicated process of consistency checking is omitted. 3. By analyzing the advantages and disadvantages of AHP method, FCE method, DEA method and so on, the principle of length complementarity is adopted, and fuzzy comprehensive evaluation method and data envelopment analysis method are used, respectively. The grey comprehensive evaluation method and the artificial neural network evaluation method are reasonably integrated with the analytic hierarchy process to form a more objective and reasonable comprehensive evaluation model. 4. Through the deep analysis of the theoretical basis and operation mode of reservoir management, the representative evaluation index is selected and the hierarchical structure of reservoir management is constructed. The principle of screening comprehensive evaluation method is summarized and established. Combining with an example of reservoir management and using fuzzy analytic hierarchy process, this paper analyzes for the first time how to select a relatively suitable evaluation method from the method of pairwise integration in this paper. 5. A nonlinear fuzzy analytic hierarchy process evaluation model suitable for reservoir management is established. In order to better reflect the prominent influence of indicators on the evaluation results, a nonlinear fuzzy analytic hierarchy process evaluation model suitable for reservoir management and management was established by combining the fuzziness, uncertainty and nonlinearity of the index system of reservoir management and management. This model not only has the advantages of the traditional fuzzy comprehensive evaluation model, but also can reflect the prominent influence of the personality index, which overcomes the deficiency of the traditional linear fuzzy comprehensive evaluation model on the outstanding influencing factors. The optimal scheme of reservoir management is determined effectively.
