Research on the Contribution Degree of Weapon Equipment System Based on Markov Chain Stable Distribution

System contribution is an index to measure the importance of equipment in the system, and it is also a key basis, First, This article constructs the cooperative interaction matrix of the equipment system by analyzing the equipment's support for the combat information, battlefield situation, and physical resources of other equipment in the system. Then, from the overall perspective, the status and role of equipment in system operations are analyzed, and a Markov chain stable distribution model is constructed as a basis for measuring the contribution of the equipment system. Finally, an example is given to illustrate the application of this method.
