Aiming at the bad repair scheduling of engineering equipment in battlefield, use the queuing theory and method to establish the repair task model. Combining with actual conditions in battlefield, realize the queuing model optimum by comparing the efficiency of different model. The priority of damaged engineering equipment was divided into levels, confirm the minimum of repair group by the intact rate of engineering equipment, realized the optimization of repair scheduling in battlefield, and use example to calculate and analyze. The analysis results showed that the model can realize the optimization of queuing theory.
