一、可靠性是产品的重要质量指标。它的定义是:在规定的条件下和新定的时间内,完成规定的功能的能力。可见,可靠性是一个用时间尺度来衡量,在用户中体现的质量指标。可靠性高,意味着寿命长、故障少、维修费用低;可靠性低,意味着寿命短、故障多、维修费用高。消费类产品发生故障,会给用户造成不便和损失;工业自动化系统发生故障,生产就会混乱甚至停产;交通控制系统发生故障,使交通混乱甚至发生交通事故;军事装备发生故障,使装备失去效能甚至造成
First, the reliability of the product is an important quality indicators. It is defined as: the ability to fulfill prescribed functions under specified conditions and at a fixed time. Visible, reliability is a measure of the time scale, reflected in the user quality indicators. High reliability, which means long life, less failure, low maintenance costs; low reliability, meaning shorter life, more problems, high maintenance costs. The failure of consumer products will cause inconvenience and loss to the users. If the industrial automation system breaks down, the production will be disrupted or even discontinued. The traffic control system breaks down so that the traffic will be confused or even a traffic accident occurs. The failure of the military equipment will make the equipment ineffective Even caused
