Abstract

In order to achieve collaborative planning, reserve and allocation for multi-tiered repositories of flood emergency supplies, a public-private collaborative LAP model with minimum weighted transit time and system cost was established with consideration of factors such as differences of supply demand for different levels of flood disasters, multi-supply location-allocation strategies, multi-tiered rescue rules and commercial storage spots. Then, an improved NSGA-II with multiple global variables was designed to solve the model. Finally, with Wuhan city taken as an example, analysis was made to find optimal solution of location, supply reserve and allocation relation for repositories at various levels, and influence of presence or absence of storage spots on objective function was compared. The result shows that the LAP model can realize comprehensive decision-making for flood emergency supplies reserve. In selection of storage spots, supply satisfaction rate is relatively uniform, thus avoiding extreme shortage of some supplies and simultaneously reducing time and cost. © 2020 China Safety Science Journal.
