针对卫星导航接收机(简称“接收机”)维修保障中过度维修与维修不足并存的问题,以维修保障费用、效能和保障资源成本为约束条件,以提高效费比为目标,建立了维修保障方案仿真评价模型,研究了接收机维修保障方案评价方法。通过仿真模拟接收机的维修保障过程,对4种典型的接收机维修保障方案进行了仿真评价,研究结果可为用户论证接收机保障性指标和决策接收机维修保障方案提供有益指导。 Aiming at the problems of over-repairing and over-repairing in the satellite navigation receiver (“” receiver) maintenance and repair, and taking maintenance cost, efficiency and resource cost as constraints, the efficiency-cost ratio is set as the goal Maintenance support program simulation evaluation model, studied the receiver maintenance support program evaluation method. Through simulation and simulation of the receiver’s maintenance and assurance process, four kinds of typical receiver’s maintenance and assurance schemes are simulated and evaluated. The results of the simulation can provide useful guidance for the user demonstration of the receiver’s protection index and the decision receiver’s maintenance and protection scheme.
