| 摘要: |
| 本文给出完备的三态部件的可靠性模型类。从静态的观点来看, 三态部件的可靠性模型有两类: (1) 成功, 降格成功, 失败; (2) 成功, 双失败。从动态的观点来看, 考虑到三个状态之间的转化关系, 其模型类相对复杂; 但是在失败率λ、维修率μ为常数的条件下, 只需六个参数(λ1 λ2 λ3 μ1 μ2 μ3) , 便可以用马尔可夫模型给出三态部件的可靠性统一模型, 并给出部件在三状态的概率函数Pi(t)的解析表达式(t为时间, i表示状态)。 |

| Abstract: |
| This paper deals with the reliability model set of three-state component. From the static viewpoint, there are two kinds of models: (1) success, degraded, failure; (2) success, failurel, failure 2. From the dynamic viewpoint, we can give the unified reliability model of three-state component with six parameters (λ1λ2λ3μ1μ2μ3) when the failure rate and the maintenance cate are constant. Moreover, we can compute the probabilities of three states at any time t. |
