In view of completing equipment operation tasks, the comprehensive quality attribution of the equipment can be characterized in the process of operations by the Equipment Operational Integrity (EOI). In this study, the concept of the Equipment Operational Integrity Control(EOIC) is put forward to control the comprehensive quality attribution of equipment effectively. The EOIC is a series of activities carried out in the process of equipment design/manufacture and service/usage to achieve the established operational integrity objectives (a certain set of durability, supportability, safety, performance, survivability and recoverability, or a certain equipment operational integrity degree, or a certain equipment readiness rate).And then, the goals of EOIC and the three basic equipment operational integrity control modes, the openloop control,coordinated control and balanced control, are analyzed as well as the connotation of EOIC. Furthermore, the basic ways to perform the EOIC are gained, which are establishment and implementations of the Equipment Operational Integrity Program (EOIP). Finally, the objectives of the EOIP are discussed briefly, including Design Information, Design Analysis and Development Tests, Full Scale Testing, Force Management Data Package and Force Management.
