Process modeling is the key step to analyzing the command and control process and winning the battle. The current modeling methods cannot well deal with the characteristics of multi-domain association and loose-coupled correlation of command and control processes in the joint battle. In view of the above problems, this study proposes an object-oriented process modeling language. The built model describes the data perspective, behavior perspective, and the complex interaction between them in the command and control process. Based on this model, process mining technology is applied to restore the command and control process, which provides an effective means to optimize the command and control process and improve process efficiency.
