Problems solved by technology

However, since the evaluation indicators are interrelated, the influence intensity between the original two evaluation indicators is bound to change due to the influence of the third evaluation indicator, and it is difficult for ANP and DEMATEL to express this deeper comprehensive influence relationship.
Moreover, the disadvantage of DEMATEL is that it regards all evaluation indicators as equal weight, which does not meet the general requirements of program evaluation

Embodiment Construction

[0095] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0096] like figure 1 As shown, this example is based on the fuzzy decision-making diagram and the gray relational analysis firearm design evaluation method, the specific process is:

[0097] Step 1 Construct the evaluation index system of the firearm design scheme:

[0098] Determine the overall goal and evaluation index system of program evaluation for specific problems.

[0099] The present invention is applied in the field of firearm design. Therefore, 7 evaluation indicators are given as an example in combination with the specific background, which are: the quality of the whole gun, the accuracy of a single shot at 100m, the failure rate, the simplicity of the structure, the maintainability, the safety, and the economic cost.

[0100] Among them, the quality of the whole gun refers to the overall quality of the fir...

Abstract

The invention relates to a firearm design scheme evaluation method based on a fuzzy decision diagram and a gray correlation analysis. The method comprises the steps that 1, an evaluation index system of a firearm design scheme is created; 2, global weights of evaluation indexes are calculated based on the fuzzy decision diagram; 3, by means of the global weights, gray relational degrees of alternative schemes are calculated, and evaluation on the firearm design scheme is achieved according to the gray relational degrees. According to the method, the global weights of the evaluation indexes are obtained through the fuzzy decision diagram; the gray relational analysis serves as an evaluation subject method, the defects that the fuzzy decision diagram does not provide the scheme evaluation subject method, and the gray relational analysis can not evaluate the mutual effect among the evaluation indexes are overcome, advantage complementation between the fuzzy decision diagram and the gray relational analysis is achieved, and therefore a set of complete firearm design scheme evaluation method which can evaluate evaluation index comprehensive influence relationships is formed.

Description

technical field [0001] The invention relates to a scheme evaluation method in the field of firearm design, in particular to a firearm design scheme evaluation method based on fuzzy decision-making graph and gray relational analysis. Background technique [0002] The firearms intelligent design system provides the possibility for the automation and intelligence of firearms design and development, and the evaluation and optimization of firearms design schemes is an important part of it. Firearms designers input design requirements for the intelligent design system, and the system will generate multiple alternatives through its reasoning module. However, designers often only want to obtain the only comprehensive and optimal solution for subsequent simulation analysis and actual production. Therefore, a scheme evaluation method is needed to realize the evaluation and ranking of multiple alternative schemes to obtain the optimal scheme. [0003] The evaluation of firearm design...
