Abstract: The problem of distributing and collecting blood for a public healthcare system is addressed in this paper. The problem is modelled as a vehicle routing problem with delivery and collection. It is an NP-hard problem that is not amenable to easy solution procedures. A heuristic proposed to find good initial solutions as inputs to an intensive search with meta-heuristics. Cluster of nodes to be visited is formed first. The nodes in a cluster is aligned to a route and then assigned a vehicle to each cluster. Using this solution as input, an intensive search, combining genetic algorithms (GA) and simulated annealing (SA) is carried out. At a significantly enhanced speed of search, encouraging results for test problems are obtained.
Keywords: global VRP; vehicle routing problem; blood collection; blood distribution; genetic algorithms; simulated annealing; cost-effective routing; blood bank logistics; blood banks.
