Collaborative crosschecking system of observed loss estimation for disaster relief management

Disaster is unavoidable but an effective disaster relief management can improve severe situations. Rapid and precise reliefs delivered to right victims are the key to improve situation after an unavoidable disastrous event. This is one of a great challenge in rural area of most developing countries as all required resources can be lacked in any moment. At the same time, there is a lot of observed information from many different sources which has to be manipulated while the relief is indeed required in the timely manner. The observed information can be over and under estimated because it depends mainly on the individual observers. Therefore to promote effective disaster relief management system, this paper presents a system for crosschecking and ranking the collected information from multiple observers to sort victims based on their priorities. The proposed system consists of three main components: the case gathering service, the crosschecking mechanism and the ranking process. Based on information of a real disastrous area suffered by the earthquake in Chiang Rai province which is in the northernmost of Thailand in 2014, the proposed system is evaluated as high availability, moderate satisfaction along with high adequate precision.
