Essential Information Forms of Condition Monitoring in a Condition Based Maintenance Context

摘要

The purpose of the study is to describe an information theory in order to achieve a fruitful discussion of information within condition monitoring in a condition bused maintenance context. The paper is based on a qualitative and interdisciplinary approach. A case study is performed at four Swedish paper mills and one condition monitoring supplier. Interviews have been the main method for data collection; however, observations and studies of artifacts arc included in the study also. The main contribution of the study is a framework that visualizes how data and five different forms of information interact and turns into knowledge about a machine's condition. These forms of information are all necessary to take into consideration when implementing and operating a condition based maintenance program. The research results state that it is relevant to allow and encourage the technicians and operators to utilize several forms of information when assessing the condition of an asset, and, thus, to not put too much trust in the condition monitoring technology alone. Also, it can be important to encourage user interface designers to reflect upon the different contexts and information forms as they design information in a condition monitoring interface.
