Implementing a web-based decision support system for disaster logistics: A case study of an evacuation location assessment for Indonesia

Abstract

Decision support systems have increasingly played a critical role in disaster logistics. This study outlines the processes required to build an effective and reliable decision support system to assess the feasibility of public facilities during an evacuation after a disaster has occurred. The purpose of this study is to build a model of a web-aided decision support system to assess the extent to which public facilities can be used as evacuation centers for the victims of an earthquake and/or tsunami. An outcome from this research is an innovative system with direct web-based accessibility, involves many decision-makers and employs multiple criteria and inputs. Even though the system has been specifically designed for evacuation scenarios in Indonesia, the system can be used for disaster scenarios in other countries as well. There are several stages in this study where the first stage identifies and selects attributes, assembles a comprehensive computer application, and employs object-oriented programming (OOP), verification and validation of the system. The role of information systems and decision support systems are critical when informing decision-makers about evacuation location alternatives and to assess their feasibility immediately after a disaster occurs. The results from this study confirm that this system can provide critical and timely insights into complex evacuation scenarios. An additional benefit of this system is the user-friendly web-based application ensuring data access from any global location with internet access.
