Comprehensive Evaluation Method for Interchange Project Based on Projection Pursuit

Comprehensive evaluation method for interchange project is built on the basic principle and the solution process of the projection pursuit algorithm. The method can determine directly the objective weights of the indexes from the project of being evaluated, and avoid the subjective negative impact on the conclusion of the determining index weights and the conclusion influenced by the index weights given by people themselves in other evaluation methods. Real coding based Accelerating Genetic Algorithm (RAGA) is proposed and applied to deal with global optimization problem of high-dimensional data effectively by optimizing the projection index function and searching for the optimal projection directional vector.
