Decision making model for detecting infected people with COVID-19

An AHP-Delphi Multi-Criteria Decision Making Model with Application to Environmental Decision-Making

The impacts of Covid-19 disease on the general health of infected people

Background and purpose: In December 2019, the release of a viral disease reported in Wuhan, China. Covid-19 is an acute respiratory disease that can have different effects. Therefore, this study carried out to observe the impacts of the Covid-19 on the general health of infected people in Tabriz city. Materials and Methods: The present study is a descriptive-analytical study that was conducted ...

A GA Model Development for Decision Making Under Reverse Logistics

  Managing products’ end-of-life and recovery of used products is gaining significant importance during last years. Therefore, managing the reverse flow of products can be an important potential for winning consumers in future competitive markets. In this context, establishing reverse logistics networks is becoming a main problem in reverse supply chains. Genetic Algorithm (GA) is utilized to s...

A BI-LEVEL LINEAR MULTI-OBJECTIVE DECISION MAKING MODEL WITH INTERVAL COEFFICIENTS FOR SUPPLY CHAIN COORDINATION

  Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problems are co...

A bi-level linear multi-objective decision making model with interval coefficients for supply chain coordination

Abstract: Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problem...
