    An Inventory Model for Hospital Blood bank with the Objective of Minimizing Wastage and Shortage

    In this research, among the levels of the blood supply chain, hospital is chosen for study because of its importance. A model of inventory management of hospital blood bank is presented. In this case, we consider some assumptions which are more realistic. These assumptions include two types of emergency and ordinary demands, young blood demand, and finally, a cross-match process. In the existing articles, although blood groups considered in mathematical models, the priority of allocation of blood groups is not considered in these articles. In this study, three mathematical models are developed with deterministic parameters. In the first model, the assumption of ordinary and emergency demand,... 

    Raising quality and safety of platelet transfusion services in a patient-based integrated supply chain under uncertainty

    , Article Computers and Chemical Engineering ; Volume 106 , 2017 , Pages 355-372 ; 00981354 (ISSN) Ensafian, H ; Yaghoubi, S ; Modarres Yazdi, M ; Sharif University of Technology
    This paper develops a stochastic multi-period mixed-integer model for collection, production, storage, and distribution of platelet in Blood Transfusion Organizations ranging from blood collection centers to clinical points. In this model, the age of platelet and ABO-Rh priority matching rules are incorporated based on the type of patient to raise the quality and safety of platelet transfusion services. At first, a discrete Markov Chain Process is applied to predict the number of donors. Afterwards, the uncertain demand is captured using a two-stage stochastic programming. A challenging aspect of applying stochastic programming in a dynamic setting is to construct an appropriate set of...
