This article focuses on risk analysis using a multi-criteria decision-making method. Due to many performed risk analyses for soft targets, we are constantly trying to find new methods for objective risk assessment. Many risk analyses are subjective, which is a problem when planning security measures and comparing results (different events, objects, places, etc.). In this text, we present our case study, which deals with the use of fuzzy TOPSIS. As a reference object, we have chosen one of the specific categories of soft targetscultural events. The goal was to find the location most at risk of violent attacks on a selected cultural event -a music concert. We then established cooperation with three experts. The completed data in the risk analysis was then compared with practice. The selected fuzzy TOPSIS method was chosen as presumably more objective. Our hypothesis was confirmed. The results were objective and consistent with practical experiences.
