Data envelopment analysis (DEA) is one of non-parametric methods for evaluating efficiency of each unit. Limited resources in healthcare economy is the main reason in measuring efficiency of hospitals. In this study, a bootstrap interval data envelopment analysis (BIRDEA) is proposed for measuring the efficiency of hospitals affiliated with the Hamedan University of Medical Sciences. The propos...

This paper considers the reliable multi-product multi-vehicle multi-type link logistics network design problem (RMLNDP) with system disruptions, which is concerned with facilities locating, transshipment links constructing, and also allocating them to the customers in order to satisfy their demand on minimum expected total cost (including locating costs, link constructing costs, and also expect...

Learning strategies play leading roles on students’ understanding information and solving problems. Not being aware of learning strategies and their use may lead to students’ failure. Furthermore, conducting research on learning strategies is difficult as they are not observable directly and selecting a reliable method is an issue. Accordingly, this paper aims to investigate the significant con...

The U.S. Food and Drug Administration is considering restricting or banning morcellation in minimally invasive hysterectomies and myomectomies (removal of fibroids) because of new reports of higher incidence of undiagnosed sarcoma in women undergoing these procedures. Research now links morcellation to the spread, or upstaging, of undetectable gynecological cancers. In July, FDA convened a 2-da...

In most multiagent systems with communicating agents, the agents have the luxury of using reliable, multi-step negotiation protocols. They can do so primarily when communication is reliable and the cost of communication relative to other actions is small. Conversely, this paper considers multiagent environments with unreliable, high-cost communication. This paper presents techniques for dealing...
