Calculation of Safety Evaluation Index Weight for Tactical Training Airspace Planning Based on Fuzzy AHP-DEMATEL

In order to solve the problems of lack of data support, excessive subjectivity of expert judgment, fuzzy semantics, and mutual coupling between indices in safety evaluation process of tactical training airspace planning scheme, an index weight calculation method based on fuzzy AHP-DEMATEL is proposed for tactical training airspace planning. The triangular fuzzy number is first introduced into the traditional AHP method for determining the initial weight of each factor. Then, the initial weight is modified to get the comprehensive weight using fuzzy DEMATEL method. The example analysis shows that the method proposed can evaluate the safety of the tactical training airspace planning scheme, and select the planning scheme with high safety. The example verifies the feasibility and effectiveness.
