Embodiment 1

[0061] This embodiment is a competitive evaluation model with alliance cooperation. Competitive evaluation method is a novel comprehensive evaluation method. The comprehensive evaluation problem generally involves multiple evaluation objects. The competitive evaluation method takes each evaluation object itself as the evaluation subject, draws on the ideas of cooperation and competition in game theory, and evaluates all parties through the cooperation and competition of weights, and finally obtains the value of each evaluation object. self-satisfaction weight. According to different competition mechanisms, competitive evaluation methods can be divided into three evaluation models: complete competition, alliance cooperation and complete cooperation. What this embodiment proposes is a competitive evaluation method with alliance cooperation. This method can well simulate the cooperation, competition and coordination relationship of the evaluation object, and reflects the main r...

Embodiment 2

[0124] This embodiment is an improvement of the first embodiment, and is a refinement of the solutions to formula (1), formula (2) and formula (4) in the first embodiment. The formula (1) and formula (4) described in this embodiment are solved by genetic algorithm.

[0125] Considering that the evaluation method is a complex nonlinear model, it is very difficult to solve the model by analytical method. This embodiment introduces a genetic algorithm suitable for solving complex nonlinear problems, and solves the problem of solving the model optimization.

[0126] The genetic algorithm described above is recorded in many documents such as "Water Resources System Engineering" (Jin Juliang et al., Sichuan Science and Technology Press, 2002).

Embodiment 3

[0128] This embodiment is a method of using the model described in Embodiment 1 to conduct a competitive evaluation with alliance cooperation. The technical roadmap is as follows figure 1 shown. This embodiment takes the water resource safety evaluation in Shanxi Province as an example to illustrate the implementation process of applying the competitive evaluation method. The specific application steps are as follows:

[0129] Step 1, the step of establishing the evaluation index system and determining the evaluation index value: used to collect relevant data, establish the consistent dimensionless index value of the evaluation index system and index value z ij .

[0130] Practical example: Table 2 (see image 3 ) is the water resources security evaluation index system in Shanxi Province, including an overall layer, 7 subsystem layers, and a total of 21 indicators. The first six subsystems are quantitative objective indicators, and the seventh subsystem is qualitative so...

Abstract

The invention relates to a competitive evaluation model and method with alliance cooperation. The competitive evaluation method comprises the steps of establishing an evaluation index system and determining an evaluation index value; solving an optimum weight through a perfect competition model; generating alliance cooperation; using an alliance cooperation model to calculate an alliance optimum weight; calculating a constrained parameter; judging the constrained parameter; using a coordination competition model to solve a coordination weight. According to the competitive evaluation model and method with the alliance cooperation, firstly the perfect competition model is built, then the cooperation alliance of a competing group is built, and the competition optimum weight in the alliance and coordination competition weights among various competition alliances are built; through the method of approaching an optimum constrained parameter in a constant iteration mode, finally the coordination competition weight and the constrained parameter are obtained. The problem that an index weight generated due to preference has large deviation is avoided, and thus the competitive evaluation method with the alliance cooperation is conducive to the good coordination of interest relationships of all parties, so that a unified weight which satisfies all parties is obtained.

Description

technical field [0001] The invention relates to a competitive evaluation model and method with alliance cooperation, which is a comprehensive evaluation model and comprehensive evaluation method for a system composed of multiple independent factors. Background technique [0002] Comprehensive evaluation refers to the process of integrating multiple evaluation index values ​​into a comprehensive evaluation value through a certain mathematical model in order to achieve a certain evaluation purpose. One of the key issues is how to reasonably determine the weight of each indicator. Commonly used subjective weighting methods, objective weighting methods, and comprehensive weighting methods all use uniform weights to synthesize the index values ​​of each evaluation object, which can increase the comparability of evaluation results between different evaluation objects, but at the same time However, the weight preference of each evaluation object is ignored. In fact, in the evalua...
