Abstract: In order to choose the jamming schemes reasonably in different stages and get the optimum efficiency under the given jamming equipment,fleet jamming schemes decision is considered as a multi-stage and multi-target system,the concept of the cooperative degree is defined based on systematic cooperation principle.Combining the fuzzy optimum selection and the dynamic programming methodology,a method of effective solving the multi-stage and multi-target problem based on cooperation is presented.This method is applied to the area of jamming schemes decision,and an all-course decision model is established.In a given tactical case,the computing process is analyzed,and the decision system interface of jamming schemes based on GUI is designed for getting the optimum decision timely and accurately in different operational situations,through simulation,the influence of the cooperative degree on decision results is analyzed under the case of different target weights.
