The optimization of operational alternatives is the key to improving decision-making and ensuring joint success. However, the complexity and cruelty of modern warfare often make decision-makers face obstacles to choice, making them hesitant on key issues and difficult to give clear decision-making information. The paper provides a convenient information-descripting tool for decision-makers to make effective decisions by modeling the operational alternatives optimization process as a multi-attribute decision-making (MADM) problem with attribute values being hesitant fuzzy element (HFE). On this basis, the paper proposes a fuzzy optimization method based on objective weighting. This method firstly uses the famous TOPSIS algorithm as the basis of the idea to establish a nonlinear programming model for solving the attribute weight vector, and further reformulate it as a convex optimization problem. Secondly, based on the proof that the convex problem has a unique optimal solution, the closed-form solution is also provided. Finally, based on the objective weighting solution, the ranking algorithm of operational alternatives is proposed, and its effectiveness is numerically verified.

本文针对属性权重未知、属性值为犹豫模糊数的作战方案优选问题,提出了一种基于客观赋权的犹豫模糊多属性决策方法。该方法首先依据传统逼近理想解(Technique for Order Preference by Similarity to Ideal Solution,TOPSIS)思想[6],在犹豫模糊数距离测度[7]的基础上建立关于权重向量求解的非线性规划模型,然后在证明该模型是凸优化问题并具有唯一最优解的基础上,给出其闭合解形式。最后,本文在属性权重求解的基础上,给出了多个备选作战方案的优劣排序算法,进而选出最优作战方案。数值实验表明,本文提出的方法具有论证过程清晰严谨、算法简明有效、结果客观实在、适用范围广泛的优点。
