Abstract
A computer-implemented method and system in one embodiment estimate the effectiveness of a dispensing plan of emergency supplies during disasters or in like scenarios, by simulating a flow of emergency supplies in a multi-echelon supply chain, dynamics of victims and progression of disaster. The performance metrics estimated in one embodiment include, but not limited to, overall coverage of distribution, inventory of supplies (e.g., shortage and surplus) and utilization of resources (e.g., shortage and surplus).
