Changes in criteria, procedure and method of maintenance or design of chemical and nuclear plants caused large-scale accidents in the past. That results in that emphasis on Management of Change (MOC) led to formulating guidelines such as Process Safety Management (PSM), which increased ability to prevent accidents. However, MOC does not appear to have performed appropriately due to issues such as lack of recognition of MOC and execution burden. This avoidance of MOC led in insufficient accumulating and sharing of information for the target changes, which resulted into fails not to prevent accidents.
Therefore, we researches MOC Supporter software system which supports execution of MOC. There are several features of our system, the most point is that our system can change procedures of MOC flexibly and control them by IDEF0 model called Plant-LCE. This mechanism enables you to analyze cause more correctly by log data which recorded procedures of implementation of MOC in an investigation of occurred accident.
This paper reports on proposal and evaluation for our procedure to accumulate log, and the design and implementation for development of MOC Supporter.
