This paper presents a competitive supply chain network design problem in which one, two, or three supply chains are planning to enter the price-dependent markets simultaneously in uncertain environments and decide to set the prices and shape their networks. The chains produce competitive products either identical or highly substitutable. Fuzzy multi-level mixed integer programming is used to mo...

We investigate a supply chain decision problem that encompasses three challenges, which cannot be managed satisfactorily nowadays with computerized decision support: dynamic, islands of planning autonomy and hierarchically coupled planning goals. We combine the existing online optimization framework by a closed-loop optimization control circuit that allows a subordinate service centre agent to ...

The rapid advancements of Information Communications Technology (ICT) are leading to extreme improvements in computing power and to the design and development of innovative products and new improved versions of the existing ones. As a result, ICT products become obsolete more quickly and in increased quantities resulting to ever-increasing waste of electrical and electronic equipment (e-waste)....
