結合DMAIC與業風險管理探討職業災害風險之研究

本研究以台電某營業區維護組線路課為研究對象，藉由六標準差之結構化DMAIC結合作業風險管理，發展一套完善之風險管理系統，探討作業時可能發生職業災害風險之個案研究。研究流程依DMAIC各步驟依序實施；定義與衡量階段，針對個案進行風險識別與風險評估，在22種危險因子中找出6項關鍵改善項目；分析階段，運用MOL及TRIZ找出其對危險因子之控制方法；改善階段，比較兩者之控制方法並提出執行風險控制之應用模型；最後，管制階段，針對高風險之危險因子提出風險控制方法包括加強專業知識、落實日常檢點、取代工具、更換媒介等，並監督控制方法是否確實執行。

The purposes of this paper are to study on a wiring branch of a maintenance team in Taiwan Power Company. The research framework is integrating DMAIC approach with operation risk management (ORM) to find out the risk factors and to control these factors by comparing ORM and TRIZ techniques. Research framework process implemented in accordance with DMAIC process. First, defining and assessing: to assess risk categories and risk factors by using cause and effect diagram which includes 22 risk factors. Second, analyzing step is by using MOL and TRIZ techniques, to identify six items which must be control. Finally, the conclusions are to propose management approach such as reinforcing professional knowledge, implementing daily inspection, replacement tool and media intermediation, and monitor the control approaches to address the risk factors.
