摘要
研究了修理更换策略,此策略是由Block 等提出的.在此策略下从部件最后一次修理起过一定时间就对该部件进行预防性维修.这不同于年龄更换,因年龄更换是从最后一次更换算起过去了一定时间.如果最后一次修理是完全修理,修理更换本质上和年龄更换一样,在小修的情况下,这是两个不同的策略.为了确定在哪个条件下一个策略比另一个策略好,在许多策略之间进行了比较,得到了几个比较结果.
The repair replacement policies are studied, Block et al introduce the concept of repair replacement. Repair replacement is a maintenance policy in which items are preventively maintained when a certain time has elapsed since their last repair. This differs from age replacement where a certain period of time has elapsed since the last replacement. If the last repair was a complete repair, repair replacement is essentially almost the same as age replacement . It is in the case of minimal repair that these two policies differ. A comparison between these two types of policies is made in order to determine when and under which condition one type of policy is better than the another, and to obtain some results of comparisons.
