Multiple imaging satellites scheduling method based on AMPL modeling language

The imaging reconnaissance satellite scheduling denotes a mission that optimizes the limited resources of several earth-observing satellites to observe the ground targets according to the demands of custo-mers.Because this mission involves the scheduling and optimization of multiple satellites,it is a challenging topic in the academic fields.After thoroughly investigating the working principles of earth-observing satellites and primary constraints in this scheduling mission,a mixed linear scheduling model that meets the requirements of multiple satellites and multiple monitoring targets in the imaging reconnaissance satellite system is proposed and the related data are used to verify the reasonableness of this newly proposed model.Then,a new method that adopts a mathematical programming language(AMPL) modeling language is employed to solve problems' i.e.,there are various algorithms to solve this kind of constraint satisfaction problem and it is hard to evaluate the efficiency of different algorithms uniformly.The data downloaded from the satellite tool kit(STK) are also experimented in AMPL modeling language to test this method.The AMPL language can adopt solvers that combine several efficient algorithms automatically.The experiment results demonstrate that,compared with normal methods,the proposed method can solve the middle and short term scheduling problem efficiently and concisely.
