A Study on the Calculation of the Maximum Tolerable Period of Disruption for Business Continuity Management of National Critical Infrastructure Systems: A Case Study in the Field of Residential Water Supply

In this study, we tried to suggest a method for calculating the maximum tolerable period of disruption (MTPD) in water supply facilities among national core infrastructure facilities. Currently, the method for estimating the MTPD of national core infrastructure includes the amount of resources available and the recovery time of functions, but there is no specific standard or methodology. By analyzing previous studies and case studies, the framework for determining MTPD using added value among economic factors was confirmed and verified. Based on the framework, it was possible to determine the applicability by deriving estimates in Gongchon. Water Purification Plant in Incheon among domestic water supply facilities. In future research, we intend to conduct verification research on the possibility of actual utilization by identifying the reduction rate of added value targeting national core infrastructure in other fields and applying the framework derived through case study.
