The only thing that is worth to mention is that the system does not check consistency between the issue and receipt dates.
The blood supply network under investigation is comprised of blood donors, mobile blood facilities, local and regional blood centers and demand points.
A hybrid solution approach, combining the -constraint and Lagrangian relaxation methods, is developed to solve the proposed model.
