Productivity Improvement of Transmission Electron Microscopes - A Case Study

This paper aims to improve the performance of Transmission Electron Microscopes (TEM) used in asbestos detection processes in a business context. Failure Modes and Effects Analysis (FMEA) were studied, identifying the critical failure modes, proposing risk reduction measures and changing maintenance practices based on the Reliability Centered Maintenance strategy. In the elaboration of the FMEA it was evident the lack of data and poor information quality regarding the reliability and maintenance of TEM. These circumstances led to the implementation of training projects to standardize operations and to the development of a software application for data collection and reports generation with relevant performance indicators (Costs, Mean Down Time, Overall Equipment Effectiveness, ...) to support operators tasks and decision-making. The approach followed and the tools developed allowed monitoring TEM productivity and maintenance performance. As a result, more informed decisions can be made that will lead to improved performance of TEM. (C) 2020 The Authors. Published by Elsevier Ltd.
