In this paper, we propose a two-stage stochastic </em><em>selective-covering-inventory-routing (SCIR) </em><em>model to supply whole blood under uncertainty. Here, set of discrete scenarios are used to display uncertainty in stochastic parameters. Both of the fixed blood center and bloodmobile facilities are considered in this study. We suppose that the number of bloodmobiles is indicated in the first stage before knowing which scenario is occurred. To verify the validation of the presented </em><em>SCIR</em><em> model to supply whole blood, we examine the impact of parameters variation on the model outputs and cost function using the CPLEX solver. Also the results of comparison between the stochastic approach and expected value approach are discussed. </em><br> &nbsp; Inventory-Routing, Covering problem, Selective Vehicle-Routing, Mobile Blood Collection 147 158 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-104-8&slc_lang=en&sid=1 Mahdi Bashiri bashiri.m@gmail.com 180031947532846005524 180031947532846005524 Yes Shahed University Elaheh Ghasemi eghasemi@stu.yazd.ac.ir 180031947532846005525 180031947532846005525 No Yaz University
