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...
