For evaluating support scheme and guiding support system design, put forward the evaluation support scheme based on combination evaluation method. Firstly, through analyze current evaluation index system, put forward the evaluation index parameters of support scheme. Secondly, the subjective evaluation method and objective weight method are sued to weight the equipment support scheme, and acquire the subjective and objective weight of index parameter. Then bring it into the combination evaluation model, which is using the minimum sum of squared deviations of the evaluation value as the objective function to gain the combination weight. Take the weight as the middle condition, and multi-attribute evaluation method is applied to evaluate the support scheme with it. Finally, select 5 application examples of equipment support scheme combination evaluation method, combine the application of analytic hierarchy process(AHP), entropy method and ideal point method to carry out integrated evaluation for equipment support scheme. Compare and analyze application results of random frontier analysis method. The analysis results show that the evaluation method can correctly reflect the objective fact with feasibility and effectiveness.
