Ontological Description of Plant Maintenance Knowledge and Its Use

Abstract

The main goal of equipment maintenance management is to keep equipment in optimal working order. Regular equipment maintenance is the key to preventing catastrophic equipment failure. It can pay off in the form of increased operational efficiency and reduce cost. Equipment maintenance service requires a wide area of knowledge, spanning from physicochemical phenomena that cause failure to the correct procedure of actual maintenance operations. This paper presents an ontological knowledge modeling framework to describe, share and inherit the knowledge. As an example of knowledge models described by the framework, functional decomposition trees of piping system maintenance are shown. The knowledge models can be used in various situations and forms, such as education of staff and quick reference for maintenance service.
