The existing equipment support systems lack the effective interface between each other, which can not carry out interoperability between systems. It adopts Petri net to model the business process of each system firstly. And then it puts forward the share integration and synchronization integration based on the trait of equipment support business, and models them respectively. Lastly, it puts forward the method of model validate. It can make the process of the systems to a organism through the business integration, which can achieve the systems building block combinations, meet the need of carrying out equipment support training systematic and organized, and meet the need of training of person who know both of the command and technology.
