Abstract:

In view of the increasingly complex equipment types, interaction relations and a large number of multifunctional equipment in the armament system of systems, the operation loop network description model of the armament system of systems containing the multifunctional equipment is established. Firstly, based on the network reliability theory, the method of calculating the armament system of systems operation capabilities is improved, and two methods of the min-path method and the Monte Carlo method based on spectral radius are presented. Then, an improved evaluation method of contribution rate is presented. Finally, an operation system example is used to verify the above modeling and solving process. The two algorithms are compared by using the random network generated by the program.The result shows that the evaluation process is feasible and accurate, and the two algorithms have different applicability to networks of different sizes in terms of calculation time and accuracy.

Key words: operation system of systems, evaluation of contribution rate, operation loop, network reliability
