摘要:

为提高雷达装备可靠性评估中指标赋权的科学性,针对主观赋权法过于依赖个体经验,客观赋权法收集到的数据较少,造成的客观赋权结果不准确的问题,采用改进后的层次分析法(analytic hierarchy process,AHP)和熵权法分别对指标进行主客观赋权,而后运用最小二乘法对主客观权重进行耦合,并采用拉格朗日法求解该模型,有效避免了单一权重的局限性问题,通过实例验证了该方法的可行性。

Abstract:

In order to improve the scientific nature of index weighting in radar equipment reliability evaluation, in view of the problem of subjective weighting method relies too much on individual experience, and objective weighting method collects less data, resulting in inaccurate objective weighting results, the improved analytic hierarchy process (AHP) and entropy weight method are used to assign the indexes to the subjective and objective weights respectively. The least square method is used to couple the subjective and objective weights, and the Lagrange method is used to solve the model, which effectively avoids the limitation of single weight. The feasibility of the method is verified by an example.

Key words: radar equipment, reliability assessment, analytic hierarchy process (AHP), entropy weight method, combination weighting
