Most process changes and modifications, which are caused by the process failure, the process life cycle and the economic environment, have been generated at industrial facilities. However, management of change (MOC) is based on basic process safety, such as change judgment, risk check with accurate technical references and risk assessment, and is difficult to carry out because of the lack of experience, knowledge, and process safety specialists. In this study, the MOC system was developed based on process safety technology and the drawing information system (DIS) oriented method. This study recommends the MOC system to industrial facilities as the setup of the obvious standard for the decision-making process, the MOC procedure based risk assessment, and the judgment and risk estimation of the process modification. The HIT and CAT modules were developed using the risk assessment checklist, HAZOP risk ranking, scenarios for consequence analysis and reporting automation. These two modules provide a clearcut view on the process risk. An effective risk-based MOC Review was performed by this new method. Additionally, this study suggests a new method for the MOC S/W system. This method was developed using a new technique which was based on the DIS system linking MOC system and the HIT and CAT Modules, including the process safety information. The goals of this method are to enhance the safety level and improve the performance efficiency.
