Study of Multi-attribute Comprehensive Evaluation Method Based on Attribute Theory

Abstract

The study of comprehensive evaluation model of attribute theory has gained fruitful achievements in both theory and practice. But at present the preference curve of the evaluator is assumed to be a smooth quadratic equation, when indicators increase, the quadratic equation fails to well reflect the change of evaluator's preference curve. By increasing the interpolation points and using Newton's Interpolation Formulae, this paper not only solves the problem but also improve the algorithm's efficiency.
