Imperfect Repair for Multi-Unit Systems and Description of Life Lengths by Conditional Failure Rates
Abstract
Results have been obtained on the influence of the working environment and of the current wear of the components on the failure rate of each component in a system. Results have also been obtained on the import on system reliability of imperfect component repair. Studies have been completed on replacement and maintenance policies for multi-unit systems. Often when a component of a system failed it is not scrapped, but instead it undergoes a repair. The repair may be successful and then it brings the item to its state just before failure. The repair may be unsuccessful and then the item is scrapped and replaced. When this is the situation then we say that the component is imperfectly repaired. Under the covered grant we studied various properties of systems with several units, each of which undergoes an imperfect repair upon failure. Upon failure, the probability of a successful repair may depend on several factors. We have considered the situation in which this probability depends on the working environment and on the wear of the components of the system. (jes)
