In order to improve the efficiency of airborne missile support, transport process is analyzed. Firstly, unitized procedures and their relations are disassembled, and duration of each procedure is got with the method of ration. Afterward, the network chart is established with logic, and time parameters of nodes and activities are calculated. Finally, critical activities are optimized with the critical path method, and the transport duration is reduced by adjusting the critical path. This method can improve support efficiency effectively.
