The Application of Correlation Dimension in the Multi-Objective Comprehensive Evaluation of the Large Complex Equipment Procurement Scheme

The multi-objectives of procurement scheme evaluation and the complicated nonlinear are pointed out in this paper according to the definition and characteristics of large complex equipments, and with regard to the defects present in the existing multi-objective comprehensive evaluation method, the assessment method of using fractal correlation dimension as the comprehensive quantitative index of multi-objective decision making in the large complex equipment procurement scheme is put forward, and the efficiency of such method is verified by the example of combat aircraft, which provides a new idea for the multiple objective decision making in the large complex equipment procurement scheme.
