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.
