In order to speed up the emergency response speed of the Naval Anti-aircraft Forces, this article discusses how to optimize readiness level transformation process of air defense equipment. Tasks are identified, composition procedures and relations are analyzed, duration of each procedure is got with time estimation method. The network diagram is established with logic and duration, time of procedures and nodes are calculated. Taking a certain type antiaircraft gun car of air defense equipment as an example for analysis, process is optimized with the critical path method, the combat readiness level transformation is reduced by adjusting the critical path, human resource balance is discussed preliminarily. The results show that this method can improve the technical preparation efficiency of air defense equipment.
