Presenting a stochastic multi choice goal programmi ng model for reducing wastages and shortages of blood products a t hospitals

One of the most fundamental components of healthcar e systems is the blood supply chain management. This chain has two significant co mponents including collecting donor’ bloods and supplying blood’s products. The m ain purpose of this paper is to concentrate on supplying blood products and present a novel constrained bi- objective mathematical model for a two-echelon bloo d supply chain network (BSCN). The aims of the proposed model are: 1) mini mize products’ waste and shortage costs in hospitals and 2) to minimize the maximum unsatisfied demand of different products among hospital demands supplied by blood transfusion centers. Some techniques are used to linearize the model’s n onlinear terms and decrease presented model’s complexity. A multi-choice goal p rogramming (MCGP) technique is used to convert bi-objective model into a single objective one. The model is solved by mathematical software under 3 different scenario s and 18 time periods in real- world BSCN. Computational results showed that hospi tals are tended in accepting products’ holding and waste costs to satisfy demand s of patients who are highly need for receiving blood products.
