Based on Rough and Evidence Reasoning Bases Overseas Security Method of Assessing Point Location

According to overseas base security point location problem, combined with the influence of the expert group is given the opinions of the site assessment, establish overseas base point location evaluation index system. On this basis, refer to the rough set and evidence reasoning method of evaluation index factor to optimize information acquisition and use historical data to get the objective information and subjective judgment to complementary, realize the subjective judgment and objective information, combining with rough set attribute reduction, simplify the index system. This method can improve the accuracy and credibility of evaluation results, make up for the overseas base security point location factors complex, calculating the defect of operability is poor, as to provide theoretical basis for overseas base security point location decisions.
