使用可用度是构成系统效能的重要因素之一 ,是系统可靠性、维修性和保障性的综合参数。由于和平时期装甲车辆的使用强度较低 ,各项时间因素复杂 ,装甲车辆的使用可用度一直是装备型号工作中的难题。本文针对使用可用度的统计计算、指标论证、工程研制和试验与评价 ,进行了装甲车辆使用可用度研究 Usability is one of the important factors that make up the system performance. It is a comprehensive parameter of system reliability, maintainability and security. Due to the low intensity of armored vehicles in peacetime and the complicated time-factors, the availability of armored vehicles has always been a challenge in the work of equipment models. In this paper, based on the availability of statistical calculation, index demonstration, engineering research and testing and evaluation, conducted a study on the availability of armored vehicles
