Developing a spatio-temporal model of risk management for earthquake life detection rescue team

Crisis management is a time-critical and collaborative activity that requires rapid assessment and decision-making. This study aims to develop a framework to increase teamwork efficiency by spatio-temporal modeling of human group activities in geospatial information systems. For this purpose, time geography framework was extended with round-robin scheduling and then was integrated in geographic information system environment to manage human activities in a spatio-temporal framework. The proposed framework enjoys the graphical presentation of the tasks to be executed, as well as mathematical modeling of the complex interactions to be managed. To validate the proposed model, activities of an earthquake life-detection team in normal and suggested framework were simulated and assessed. An average improvement of 18.69 % (in time and the number of rescuers) was observed using the proposed framework. The suggested framework helps to resolve multidimensional problems in risk management.
