Abstract : The problem of distribution of blood has been extensively studied, but models relating to
different blood types have not been specifically considered in the literature to the best of our
knowledge. This paper describes a new mathematical model for optimising blood distribution in
residential areas. A Lagrangian relaxation-based matheuristic is developed to solve the problem.
Hypothetical data sets were generated to mimic real blood distribution system in an urban
setting. Results obtained using CPLEX solver on the AMPL platform reveal that the model
described in this study is able to achieve quality results within very short times. Specifically, the
number of located blood facilities is minimized for each problem instances as well as covering
much of the demand points on the distribution network. We observe that the proposed system,
when compared to the existing system, provides a better approach to blood distribution and is
adaptable to related areas of supply chain.
