Flexible and dynamic supply chain network design problem has been studied by many researchers during past years. Since integration of short-term and long-term decisions in strategic planning leads to more reliable plans, in this paper a multi-objective model for a sustainable closed-loop supply chain network design problem is proposed. The planning horizon of this model contains multiple strate...

background: functional appliances such as bionator have been used to treat class ii malocclusion. the purpose of this study was to compare the skeletal, dental and soft tissue effects of bionator appliances with multi-p (a newly developed appliance) in the treatment of class ii malocclusion. subjects and methods: 45 class ii children were chosen and randomly assigned to either the bionator or m...

AIM Because of increasing awareness of variations in the use of pancreatic exocrine replacement therapy, the Australasian Pancreatic Club decided it was timely to re-review the literature and create new Australasian guidelines for the management of pancreatic exocrine insufficiency (PEI). METHODS A working party of expert clinicians was convened and initially determined that by dividing the t...

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 introduce an extension to an architecture-independent tool (VISTA) for creating displays of cognitive model behavior, the Categorical Data Display (CaDaDis). Our display offers several views of categorical data. It includes a standard Pert Chart showing tasks by category (or resource), a Nonstandard Pert Chart that shows the temporal dependencies, and a Gantt chart that helps show occurrence...
