Andrew is the author of the Process Plant Reliability Engineering article series.
Whilst most reliability literature is concerned with “product” reliability engineering, the described methods (e.g., Weibull analysis and FMEA) find relatively little application in a process plant environment. At first glance, the reason for this would seem to be the ratio of (many) Assets to (few) Engineers. However, the real reason is much more interesting. It is because the traditional methods were developed for application in “simple” and “complicated” systems, whereas a process plant is a “complex” system. Our response to this situation has been to trivialize the complex system behavior, for example in the form of a risk matrix. An alternative response would be to apply methods suited for application in complex systems. For example, simulation is absolutely necessary to make optimal decisions in complex systems. The aim of this article series is to present concepts, methods, and tools for tackling the reliability engineering problem in the context of a complex stochastic production system.
