Benders decomposition algorithm for a green closed-loop supply chain under a build-to-order environment

Nowadays, researches pay more attention to environmental concerns consisted of various communities. This study proposes a multi-echelon, multi-period closed-loop supply chain (CLSC). A comprehensive model considers the selection of selection of technology and environmental effects. The supply chain is under a build-to-order (BTO) environment. So, there is not a final product inventory. Also, th...

Developing a Mixed Integer Quadratic Programing Model with Integer Numbers for Designing a Dynamic closed-loop Logistics Network

Logistics Network Design includes network configuration decisions having long-standing influences on other tactical and operational decisions. Recently, regarding environmental issues and customer awareness and global warming closed-loop supply chain network design is taken into consideration. The proposed network for the integrated forward and reverse logistics is developed by formulating a cy...

A Simple Algorithm for Closed-Loop Control of Stepping Motors

Stepping motors are normally operated without feedback and may suffer from loss of synchronization. This can be prevented by the use of positional feedback. A simple control algorithm is developed which allows a stepping motor to operate effectively in open-loop mode as long as it remains synchronized, but which recovers from loss of synchronization following a disturbance. The control algorith...

A Network Design Model for a Resilient Closed-Loop Supply Chain with Lateral Transshipment

This paper develops a model for the closed-loop supply chain network design with disruption risk. By considering supply disruption, two factors including extra inventory and lateral transshipment are used as resilience strategies. The main purpose is to reduce the supply chain costs due to the location decisions, quantity of products between different levels and lost sale. Disruption in a suppl...
