In order to realize the fact that operational tasks can be decomposed flexibly with new tasks random adding, role-based approaches for operational tasks model and the flexibility decomposition are proposed. Firstly, aiming at the shortcomings of previous task decomposition methods, operational role concepts are introduced to design a computing framework of task flexibility decomposition. Within the framework, task structure matrixes are constructed for tasks decomposition with the mapping relations of information interaction and action process among tasks. On basis of this, via giving operational decomposition granularity, a flexibility approach of operational task decomposition is put forward with three parts about task decomposition granularity adjustment, tasks module partition with different operational role patterns and task decomposition scheme evaluation. Finally, as an application case shown, it is validated that the proposed approaches for tasks modeling and decomposition are available. By comparing with previous decomposition approaches, the proposed approach, within three types of operational roles, has strong environmental adaptability and scheme diversity, which can restrain calculation complexity increment for realizing task flexible decomposition effectively. © 2016 Beijing Institute of Aerospace Information. 展开更多

Combined with the fact that information asymmetry between two belligerent parties is very common in information-based warfare, the bidirectional influence of asymmetric information on both sides is analyzed. A new damage coefficient is formed based on the analysis, and a generalized Lanchester warfare model characterized by information asymmetry effect is built. According to the staggered transformation of information asymmetric degree resulting from the changing tactic of both sides by turns, a method for approximate solution of the model is presented by translating the information asymmetric degree as a ladder function, and both examples of the solving model and further discussion about the solution are given. The results indicate that the model can serve as a reference to analyze and forecast the course of war quantitatively. © 2017 Beijing Institute of Aerospace Information. 展开更多
