This paper studies a multi-trip routing problem of a shuttle fleet to transport blood units from collection sites to a blood center. In this problem, the blood units intended to produce platelets and cryoprecipitate must be processed within eight hours from their donation and arrive at the blood center at a time less than its closing time to guaran...

The management of the blood supply chain is considered of vital importance. The unavailability of blood may cause deaths and complications for patients. Conversely, wastage of blood generates high costs. Optimal decision making in the supply chain of blood products is required to minimize the levels of shortage and wastage. Due to the complexity an...

We propose the use of additional vehicles, called shuttles, that pick up the collected blood by the bloodmobiles. Hence, bloodmobiles can continue their tours without...
