Risk Analysis and Priority Determination of Risk Prevention using Failure Mode and Effect Analysis Method in the Manufacturing Process of Hollow Core Slab

Abstract

Risk management assists the practitioners in manufacturing industries to determine types of risk and the best way to treat the risk. Source of risk and the uncertain condition following the risk can be predicted, as well as the impacts of risk and the solutions to overcome the risk. Identifying potential failure and the impact of risk are considered as an important fields in research on risk management. This study was focused on identifying strategy to overcome the risk in the fabrication process of hollow core slab using. Failure Mode and Effect Analysis method will be implemented in this study in order to achieve the aim of this study. This study found 23 failure modes and the highest risk priority is the realizing-agent spraying which is not evenly distributed on the mold in mold cleaning process. The strategy to overcome this failure mode risk is to spray the releasing-agent two layers. Meanwhile the most frequent failure mode is the overhead-crane hoist-cable broken off and machine breakdown. The strategy to overcome this failure mode is to employ mechanical engineer to carry out regular inspections and maintenance.
