Abstract
The integration of relief supply chain operations is critical for the timely supply of relief items to the areas affected by disasters. This work considers a two stage relief supply chain providing relief kit to the areas affected by flood type disaster. Floods often cause path blockages that affect the supply of relief items. A mixed integer linear programming model is formulated for the integrated production and outbound distribution scheduling problem considered and is solved by using a mathematical solver. Since solvers have computational issues in solving realistically sized problems, a Selective Hybrid Genetic Algorithm (SHGA), which performs a selective local search, is proposed. The proposed SHGA produces near optimal solutions in relatively short computation times which is beneficial for quick decision making. A sensitivity analysis is also performed and the path disruption is found to be the most significant input parameter influencing the model.
