Effectiveness Evaluation Model for Public Alert Systems

Kurzfassung

Effectiveness of alerting systems can be understood from different points of view, varying from the economic standpoint to the operational perspective. This paper presents a method for evaluating the effectiveness of public alert systems, assuming they are effective if the alert messages can be properly received and understood by the population at risk. Only under these conditions, the population at risk can be informed about the facts and the recommended protective action to be taken. The chosen approach for this analysis is a qualitative/quantitative method to evaluate the capability of different communication channels used to alert the population to fulfill a number of requirements and understand their complementarities if a multi-channel approach is adopted.
