Crisis-induced vaccine supply chain management has recently drawn attention to the
importance of immediate responses to a crisis (eg, the COVID-19 pandemic). This study …

Economic development and rising urbanization rates have generated large amounts of
municipal solid waste (MSW). Also, over the past few decades, inefficient waste …

Based on the concept of ambidexterity, we develop a multi-objective, multi-product, and
multi-period model to integrate planning for research and development (R&D) and …

During Covid-19, medical service networks (MSNs) faced new challenges, such as an
impressive increase in hospital visits, a shortage of hospital beds and staff, and insufficient …

Over the past few decades, inefficient waste management has caused environmental

This paper investigates a new bi-objective parallel machine scheduling and location
problem: selecting locations for available machines, assigning jobs to these located …

In this study, a multi-objective nonlinear model is used to design a closed-loop supply chain
network. We consider a multi-period, multi-product and multi-stage manufacturing model by …

The COVID-19 pandemic happened exactly when no one expected it and many people died
due to the lack of medical equipment. Although pulse oximeters and thermometers were …

This work addresses a new bi-objective parallel machine selection and job scheduling
