新型**的发展，要求悬挂物管理系统(SMS)应具有**系统的开放性和功能模块的集成性，软硬件的划分原则不再是简单的功能分区。针对当前系统软硬件资源浪费的问题与系统硬件部分的设计面向开放式体系结构的要求，采用带权有向无环图对软硬件配置进行建模，并用代换公式将之约简。首次利用粒子群算法对悬挂物管理系统进行硬件划分研究，分析了任务节点的功耗情况。性能测试仿真实验结果与分层设计的划分实例表明，划分后的系统硬件资源利用更加合理，为航空兵部队的装备改进提供有价值的参考。

With the development of new weapons Store Management System (SMS) is required have open weapon system and integrated function modules the principle of hardware/software partitioning is no longer just based on functions.According to the problem of resource waste in present system and the demand of open system structure a Directed Acyclic Graph (DAG) model was constructed then reduced with formula.The particle swarm optimization was used in SMS hardware partitioning and power consumption of task nodes were analyzed.The results of performance testing simulation and partition example of delamination design show that the utilization of hardware is more reasonable which can be taken as a reference for further improvement.
