Resource scheduling is an important part for joint operation, and reasonable combination of all kinds of operation resources will supply a guarantee to the operation.But during the operation, it is difficult to keep all the operation resources in good condition all the time.Once the resources can not be used, it will influence the accomplishment of the whole mission.In this paper, the Multi-Dimensional List Scheduling (MDLS) algorithm is improved and simulation is made, thus to reach the goal of resource rescheduling and guarantee the accomplishment of mission when certain resources are unavailable.
