A Maintainability Model for Complicated System

摘要

In general maintainability model, one hypothesis is that only one failure occur at same time, but for a complicated system it is frequent that tow or more failure could occur during a defined mission be going. In this case the existed maintainability model couldn't longer reflect the maintainability of the system completely. In this paper, a mathematics model that could reflect the maintainability of a complicated system(a MTTR model that considering multi-failure)is introduced so that the model can reflect the maintainability of a complicated system more truly. If it is used to predict the maintainability of a complicated system, it can predict the maintainability level of the system more accurately.
