Abstract: By analyzing the factors which influence the hybrid force disposition, an optimization model about hybrid force disposition is found according to the principle of hybrid force disposition. To this kind of NP-hard combinational optimization problem, Particle Swarm Optimization（PSO） algorithm based on linearly decreasing weight is brought forward for the optimization problem, the particles’ coding and step of algorithm optimization are given. The ideal force disposition is obtained for an example by setting the proper algorithm parameters in the software Matlab, a new way is provided for solving the hybrid force disposition problem.

摘要： 通过对影响混编群兵力部署因素的分析，结合混编群兵力部署原则，建立了混编群兵力部署优化模型。针对该类NP难组合优化问题，提出了一种基于线形递减权重离散粒子群算法，给出了粒子的编码及其寻优操作步骤。通过设置适当的算法参数，利用Matlab编程实现对应用实例的仿真，取得了理想的兵力部署效果，为解决混编群兵力部署优化问题提供了一种新的途径。
