Abstract: Equipment maintenance task scheduling in wartime can adjust equipment maintenance plan rapidly based on real-time updated maintenance task information, and it plays a significant role in combat support. For the insufficient consideration of time uncertainty factors of equipment maintenance task scheduling in wartime, an equipment maintenance task scheduling model is established. In the model, the randomness of maintenance task appearing and the uncertainty of maintenance time as well as maneuver time are regarded as driving conditions, while maintenance time and load capacity are regarded as constraint conditions. To get the maximum value of the sum of repairing equipment important degree, an equipment maintenance task scheduling is carried out, timely adjusting equipment maintenance plan and planning optimal maintenance task path. To acquire the result of equipment maintenance task scheduling rapidly and accurately, an improved Max-Min Ant System (MMAS) is applied. At last, the timeliness and the effectiveness of the method are verified with an example.
