This paper is organized as follows. In section I, we introduce the schedule problem and abstracted conception of resource, requirement and their relationship. In section II, a series of mathematical models are provided. A multi-dimentional target vector is first defined which includes the element called match factor. A factor reflects the effectiveness of resource and elements called invalidation factor and invalidation time.
Factors reflect the healthy status of small satellite systems.
Secondly, we introduce a strategy of importance priority and FIFS under the same importance. The dynamical schedule model presented by this paper may be used in the phase of conceptual design of small satellite systems and it also can improve the automatization of stations and ensure big business of small satellites sequentially. Meanwhile, the model is also the same with the dynamical multidimensional control problem of multi-object and limited resource.
