A scenario-based robust time–cost tradeoff model to handle the effect of COVID-19 on supply chains project management

The COVID-19 pandemic outbreak deeply impressed supply chains in different aspects. In response to this unexpected situation, chain managers have decided recover and reinforce their chains. Considering the expanse of these decisions, project management principle tools seems inevitable successfully manage transformation from before post-pandemic (SCs). study, problem time–cost tradeoff is extended time, cost, risk tradeoff. factor considered convey uncertainty arising situation. Since projects are affected by level expansion countries ruled out various quarantine policies (isolation, quarantine, social distancing, lock-down), influenced accordingly. Therefore, a scenario-based robust optimization model proposed deal with problems reflect effects global on managing addition, lock-down) as prevalent been investigated separately. To illustrate model, real-world case study emerging economy Iran examined using approach. results indicated that can use designed approach tool for flexible adaptable decision-making framework dealing such COVID-19.
