Att värdera avbrott i samhällsviktiga verksamheter

Sammanfattning: Critical infrastructure is essential for a functioning society because of the services and goods they provide. Within these infrastructures there are several departments whose functionality is critical to society and when exposed to stress can lead to societal consequences. Therefore, it is important for the department within the critical infrastructure to have a solid crisis and continuity preparedness. This report investigates the preparedness in departments of critical infrastructures within City administrations and the fire brigade in Malmö, focusing on values and trade-offs of interruptions in dependencies in terms of magnitude and time. The evaluation of interruptions was conducted through surveys and interviews with people working with crisis management in these departments. The investigation found that this type of interruption where both magnitude and time are handled is rarely included in the guidelines for continuity management issued by the Swedish Civil Contingencies Agency (MSB). The result of the report is shown through several preference curves based on Multi-Attribute Utility Theory (MAUT) with magnitude and time as attributes. These preference curves could provide new insights into the ability of specific functions in the departments within the critical infrastructure to handle such stresses. And this method could give decision-makers guidance on where to prioritize actions by comparing the preference curves endurance between the departments. The conclusion is that this method could be used as a complement for continuity management in critical infrastructures which could give higher robustness to stress from various sources, in terms of both time and magnitude, and support decision makers in prioritizing preventative actions.
