Abstract:

In order to deeply analyze the influence of the performance degradation of each equipment system in system of systems on interdependency among them and accurately grasp the evolution law of the current efficiency of each equipment system under the dual influence of its own performance degradation and interdependence. The traditional functional dependency network analysis (FDNA) method is improved and the self-effectiveness degradation coefficient is introduced to give a dynamic FDNA algorithm considering time factor. And the performance degradation model of the equipment system in system of systems is constructed based on the Markov process to provide the corresponding basis for the calculation of self-effectiveness degradation coefficient. Then, a task capability dependency analysis method of weapon system of systems based on the functional dependency network is proposed, and the feasibility of the method is verified by a case.

Key words: weapon system of system, performance degradation, functional dependency network analysis (FDNA), Markov process, dependency analysis
