基于改进层次分析法的在轨服务飞行器机动策略评估

Maneuver Plan Evaluation for Orbital Service Vehicle Based on Improved Analytic Hierarchy Process

在轨服务飞行器(Orbital Service Vehicle,OSV)在执行服务任务时,可以采取多种方案和策略接近服务目标。为得到优化可行的机动策略,可以运用适当的指标体系和评估算法对各方案进行统一比较和选优。根据效能评估的相关理论,提出了基于改进的层次分析法的OSV机动策略评估方法,并用具体算例验证了该方法的可行性和可信性。该方法经过适当的细化可以推广应用于其它航天任务的决策过程中。

Several maneuver plans can be adopted for the Orbital Service Vehicle（OSV） to approach the target during an orbital service mission.Proper parameter system and evaluation algorithm can be used to compare and select the maneuver plans,in order to get the more optimized and feasible one.Therefore,a method to evaluate the OSV maneuver plan based on improved analytic hierarchy process is presented in this paper,according to the theory of efficiency evaluation.The feasibility and credibility of the method is demonstrated by the concrete algorithm example in the following description.This method can be further applied in the decision making of other space missions after appropriate optimization.
