Design of Blood Supply Chain Optimization Model Using Fuzzy Approach and Markov Chain under Demand and Supply Uncertainty

Taher kouchaki tajani; Ali Mohtashami; maghsoud Amiri; Reza Ehtesham Rasi

Volume 22, Issue 72 , May 2024, , Pages 73-124


  In this paper, we have proposed a model based on Mixed Integer Non-Linear Programming for the blood supply chain under conditions of uncertainty in supply and demand, from the stage of receiving blood from volunteers to the moment of distribution in demand centers. The challenges addressed in this optimization ...  Read More

Routing- Location for Hazardous Materials with Considering Risk Criterion in Hub Framework Network by Meta-heuristic Algorithms

Ali Mohtashami; Amir Hossein Niknamfar

Volume 17, Issue 53 , July 2019, , Pages 219-246


  Hazardous materials which are materials due to their chemical and physical properties impose significant risk to the safety of people and the environment. It's more complex routing transport of such material than normal materials. The Combination of the two subjects as the problem of locating and routing, ...  Read More
