An Integrated Model with Conservative Levels to Evaluate the DMUs Efficiencies for Uncertain Data

Allocation models for DMUs with negative data

The formulas of cost and allocative efficiencies of decision making units (DMUs) with positive data cannot be used for DMUs with negative data. On the other hand, these formulas are needed to analyze the productivity and performance of DMUs with negative data. To this end, this study introduces the cost and allocative efficiencies of DMUs with negative data and demonstrates that the introduc...

Integrated Analytical Model for Relief Logistics in Uncertain Conditions

The life of many people in the world is under the danger because of the accidents and unpredicted diseases, which require relief. Since, most of such cases occur in unpredictable condition, for an appropriate planning, the uncertain conditions should be investigated. Consequently, this paper investigates the integrated and multi-step process of locating, assigning and routing the air and la...

A data-integrated simulation model to evaluate nurse-patient assignments.

This research develops a novel data-integrated simulation to evaluate nurse-patient assignments (SIMNA) based on a real data set provided by a northeast Texas hospital. Tree-based models and kernel density estimation (KDE) were utilized to extract important knowledge from the data for the simulation. Classification and Regression Tree models, data mining tools for prediction and classification,...

An Integrated Model for the Iranian General Dentistry Curriculum

Background: The purpose of this study is to present an integrated model for the Iranian general dentistry curriculum. Methods: In this study, the qualitative method of focal groups was used. First, using library studies and analysis and interpretation of the resulted information, possible types of integration in the dental curriculum and real experiences of some of the world's leading universit...
