Optimal wholesale facilities location within the fruit and vegetables supply chain with bimodal transportation options: An LP-MIP heuristic approach
We developed a mixed integer linear programming (MILP) and a heuristic solution for regional food access through optimal hub locations. If the food mile becomes overly restrictive to ensure local food sourcing, some regions in the network will not be able to provide local food through land transportation. Bounded upper cap of the hubs in some cases will operate with excess capacity because insufficient quantities of food will be available. There is always a trade-off between transportation costs and fixed costs of building hub capacity.
