The task of maintenance organization is very heavy at wartime. The usability of armaments may be greatly improved by efficient task scheduling. In order to recover the battle effectiveness of units in battlefield as fast as possible, dynamic maintenance scheduling models with subject taken into account were built on the basis of analysis the feature of maintenance task. Maintenance task scheduling problem is very complicated. So it is decomposed into two sub-problems: static maintenance task scheduling and dynamic maintenance task scheduling problem with subject taken into account. Corresponding mathematic models were built to these sub-problems and their solutions were proposed. Dynamic maintenance task scheduling with subject taken into account is on the basis of static maintenance task scheduling. With the task changing in battlefield, dynamic task scheduling can be realized by repeatedly call of static maintenance task scheduling with subject taken into account. The experimented results show that dynamic maintenance task scheduling method with maintenance subject taken into account is valid.
