چکیده
Abstract The provision of medical equipment during pandemics is one the most crucial issues to be dealt with by health managers. This issue has revealed itself in context COVID-19 outbreak many hospitals and centers. Excessive demand for ventilators led a shortage this several Therefore, planning manage critical hospital transfer between different event pandemic can used as quick fix. In paper, multi-objective optimization model proposed deal problem hub network design distribution face epidemic diseases such Covid-19. objective functions include minimizing costs, destructive environmental effects transportation, delivery time hospitals. Since it difficult estimate demand, especially conditions disease outbreaks, parameter considered scenario-based under uncertain conditions. To evaluate performance model, case study eastern region Iran investigated sensitivity analysis performed on outputs. changing cost parameters related building infrastructure hubs also vehicle capacity analyzed too. results that produce justified optimal global solutions and, therefore, solve real-world problems.

A ROBUST OPTIMIZATION MODEL FOR BLOOD SUPPLY CHAIN NETWORK DESIGN
The eternal need for humans' blood as a critical commodity makes the healthcare systems attempt to provide efficient blood supply chains (BSCs) by which the requirements are satisfied at the maximum level. To have an efficient supply of blood, an appropriate planning for blood supply chain is a challenge which requires more attention. In this paper, we address a mixed integer linear programming...

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
A conic quadratic model for supply chain network design under hub, capacity, delay and lost sale
In this paper, mathematical models are proposed for simultaneously modeling location and inventory control decisions in a four echelon supply chain network considering capacity. The echelons considered in this paper include suppliers, warehouses, hubs and retailers. The aim of the model is to minimize the location, transportation and inventory control costs. Hence, a non-linear mixed integer pr...
