Abstract

Cost functions, associated with the gamma process for modelling deterioration, are extended to include multiple failure modes. The application of these cost functions is demonstrated by an example in the process industry. We consider an elbow in a pipeline, which is susceptible to thinning due to corrosion and stress corrosion cracking. The optimal inspection interval and replacement levels are determined graphically and the effect of data (un)availability on the result is discussed.
