Читать книгу System Reliability Theory - Marvin Rausand - Страница 53

The main role of the reliability engineer in normal operation is to track items causing abnormally high maintenance cost and production losses or service outages, then find ways to reduce these losses or high costs. The role of a reliability engineer may vary from company to company, but the overall goal is always the same: reduce maintenance costs as much as possible without interrupting system operation.

Another main role of the reliability engineer in this phase is to collect, analyze, and present reliability data. This topic is treated in detail in Chapter 14.

Reliability has to be designed and manufactured into an item. It is too late and too costly to wait until the item is produced. Reliability considerations must be integrated into all steps of the development process. This book presents the main theory and many of the required methods and tools for reliability engineering, but reliability engineering also requires a number of methods that are outside the scope of this book. When to carry out an analysis, which data are available at this stage, and how to update and use the results are central questions in reliability engineering that are not covered in this book.
