Knowledge Management for Handing Down Elderly Workers’ Expertise and Skills to the Next Generation in the Batch Process

Abstract

We focus on extracting the know-how of skilled operators who carry out batch process operations at a chemical company. We start by using a time-series analysis sheet to analyze each problem card recorded in the work place; on the basis of the analysis results and by interviewing a skilled operator, we try to extract know-how and tacit knowledge. We also show various scenarios that could arise when a malfunction occurs by drawing an event tree chart that illustrates multiple protection layers from the viewpoints of safety, quality, cost, etc. This chart shows the appropriate actions to be taken at each stage of an event. As a result, we can compile manuals for handling abnormal situations. This enables the comprehensive recording of operational know-how of the plant and helps operators to be in command of abnormal situations.
