According to extended manufacturing was a new networked manufacturing model, which was oriented to armament and another complex products, the methods of extended task planning based on tasks correlation were proposed. Firstly, through comparison of extended manufacturing and normal networked manufacturing, the necessity of extended tasks planning was analyzed. Secondly, The definition of extended tasks 2-dimensional correlation and its evaluation criterion oriented extended manufacturing were given, and the extended task correlation matrix was established, by which complicated correlation including material transferring and correlation degree of extended tasks was described; then extended tasks were decomposed using PSO algorithm, and sets of extended tasks were generated. At last, the application process of the extended task modeling and decomposition was discussed.

针对扩散制造这种面向复杂武器装备批量生产的网络制造模式，提出了基于相关性的扩散任务规划方法。通过对比扩散制造与一般网络化制造的不同，分析了扩散任务规划的必要性;然后，定义了扩散制造两维相关性概念及面向扩散制造的相关性评价准则，建立了扩散任务相关性模型，用以描述扩散制造过程中任务间物料转移，结构、功能以及工序相关性等复杂关系;在此基础上，提出了粒子群聚类优化分解算法，实现了“内紧密，外松散”的任务集划分;最后，通过实例讨论了扩散任务规划的应用过程。
