Abstract
  Data Envelopment Analysis (DEA) is one of the non-parametric methods for evaluating each unit's efficiency. Limited resources in the healthcare system are the main reason for measuring the efficiency of hospitals. Because Operating Rooms (OR) are the most vital part of any hospital, we determine the ...  Read More

3. A Taghuchi based Multi Objective Time-Cost Constrained Scheduling for Resource Availability Cost Problem: A Case Study

M. Rabbani; S. Aghamohamadi; H. Farrokhi-Asl; M. Alavi mofrad

Volume 6, Issue 4 , Autumn 2017, , Pages 269-282

http://dx.doi.org/10.22105/riej.2017.96349.1008

Abstract
  In this paper, a new multi-objective time-cost constrained resource availability cost problem is proposed. The mathematical model is aimed to minimize resource availability cost by considering net present value of resource prices in order to evaluate the economic aspects of project to maximize the quality ...  Read More

4. Presenting a New Approach toward Locating Optimal Decoupling Point in Supply Chains

M. Rabbani; H. Yousefnejad; H. Rafiei

Volume 3, Issue 1 , Spring 2014, , Pages 49-54

Abstract
  This article attempts to cope with one of the most vital strategic decisions in the supply chain design in terms of manufacturing context. The issues of finding the best position of Customer Order Decoupling Point (CODP) in a production line have been taken into consideration by many researchers in recent ...  Read More
