以系统效能为目标的装甲车辆可靠性、维修性、保障性和测试性权衡分析

在装甲车辆论证过程中，权衡分析是确定可靠性、维修性、保障性和测试性（RMST）定量要求的关键环节，但目前缺少科学有效的方法。提出以系统效能为目标的装甲车辆RMST权衡分析方法。基于装甲车辆使用和维修管理的实际情况，构建了由战备完好率、任务可信度和固有能力三部分组成的装甲车辆系统效能模型。在系统效能模型的基础上提出两种RMST权衡分析方法，即基于比较的权衡分析方法和基于灵敏度的权衡分析方法。该方法为合理地确定装甲车辆RMST定量要求，提高装甲车辆系统效能提供一种有效手段。

Trade-off Analysis of Reliability/Maintainability/Supportability/Testability of Armored Vehicle Based on System Effectiveness

Trade-off analysis is a key link of quantitative requirement determination of reliability/maintainability/supportability/testability (RMST) in the process of armored vehicle demonstration, but an effective method is absent. A method to balance RMST of armored vehicle based on system effectiveness is proposed. Based on the operation and management conditions of armored vehicle, an armored vehicle system effectiveness model is set up, which is made up of three parts, including operational readiness, battle dependability and capability. Two kinds of methods are proposed for the trade-off analysis of RMST, which are trade-off analysis methods based on comparison and sensitivity, respectively. This provides an effective method to determine RMST quantitative requirement of armored vehicle, and improve system effectiveness.
