Modeling and Analysis of Air Defense Process for Warship Formation Based on PEPA

Air defense process of large surface warship formation is a very important part in the combat. In current research, however, less attention has been paid to the whole process of air defense of surface warship formation in macro perspective. This paper applies the PEPA method to model the air defense process of surface warship formation. The cooperation among elements has been taken into account in the established model and the basic process of the air defense has been described as well. By analysis it shows the performance of air defense of warship formation increases with the increase of elements’ quantity, and finally reaches a stable value. Then the composition of the basic formation elements that the interception capacity of air defense operation attains the maximum can be obtained from the test results. Therefore, it provides a new quantitative method to deal with the air defense problem of warship formation.
