DECISION SUPPORT TOOLS FOR SELECTION OF EXTERNAL PROTECTIVE COATING FOR PIPELINES

摘要

A good coating is one with high performance and durability; has a low surveillance and maintenance requirement; is easily applied with no health risks and finally is cost effective. It is unlikely that a single type of coating would be able to satisfy all these needs. Thus, a decision support tool is needed to help identify the most appropriate choice. This paper presents three simple methods for this selection process, and allows the judgment of more than one expert to be aggregated in order to reach a consensus. An example is presented which demonstrates the application of these methods, by providing the decisionmaker the ability to weigh options and set priorities in deciding on the best compromise solution for a corrosion coating material.
