The Multi-Index Incidence Projection Decision Method under the Information of Three-Parameter Interval Grey Number

Based on the method of interval incidence degree, the grey relative incidence is expanded, and the decision-making information, for the three-parameter interval numbers, is also explored. In line with the degree of closeness between the effect vector of various schemes and the effect vector of optimal scheme or critical scheme, the ideally and critically relative incidence decision models, under the information of three-parameter interval grey number, are first presented. And then, the concepts of standard effect scheme and substandard effect scheme are proposed, and, under the information of three-parameter interval grey number, the ideally and critically relative incidence projection decision models are established. By means of the relative incidence projection, we finally construct the linear comprehensive incidence projection decision model and the product comprehensive incidence projection decision model. For the six decision models above, the corresponding algorithms are specified, and the practicality and effectiveness of the proposed six models are illustrated by examples.
