Abstract:

In order to overcome the problem in the assessment of the investment project, determining the index weight, subjectivity is proposed through the least-square method determining the index weight.It is the optimal method to have preference information and objective information entropy weights of output, with least-square method for tools, set up the index weight determination model. This method can be applied to the evaluation decision more accurate objective, realistic effectively. This method overcomes the evaluation process determines the index weight, while the subjective judgment to improve the accuracy and scientific and practical value.

Key words: post-evaluation, least squares method, index weight, information entropy
