EFFICIENCY MEASUREMENT OF NDEA WITH INTERVAL DATA
Data envelopment analysis (DEA) is a non-parametric technique for evaluation of relative efficiency of decision making units described by multiple inputs and outputs. It is based on solving linear programming problems. Since 1978 when basic DEA model was introduced many its modifications were formulated. Among them are two or multi-stage models with serial or parallel structure often called net...

نظریه هوش چندگانه قسمتهای متفاوت هوش بشری را مورد بررسی قرار می دهد که با شناخت آن شخص به درک بهتری از توانایی های خود میرسد و در نتیجه سعی در استفاده از آن جهت یادگیری بهتر میکند. همچنین با شناخت استعداد دانش آموزان، فرایند یادگیری بهتر میشود. هدف از انجام دادن این تحقیق بررسی رابطه بین هوش ریاضی و استعداد یادگیری زبان انگلیسی میباشد. برای انجام این تحقیق از پرسشنامه هوش ریاضی که توسط شیرر در ...
Proposing a Robust Model of Interval Data Envelopment Analysis to Performance Measurement under Double Uncertainty Situations
It is very necessary to consider the uncertainty in the data and how to deal with it when performance measurement using data envelopment analysis. Because a little deviation in the data can lead to a significant change in the performance results. However, in the real world and in many cases, the data is uncertain. Interval data envelopment analysis is one of the most widely used approaches to d...
متن کاملMeasurement of ocular surface irritation on a linear interval scale with the ocular comfort index.
PURPOSE To examine the psychometric properties of the Ocular Comfort Index (OCI), a new instrument that measures ocular surface irritation designed with Rasch analysis to produce estimates on a linear interval scale. METHODS The OCI was self-completed by 452 subjects. Some of them repeated the questionnaire, to aid in determining its reliability and test-retest repeatability. Ten versions wer...
متن کاملFoundation for a Time Interval Access Control Model
A new model for representing temporal access control policies is introduced. In this model, temporal authorizations are represented by time attributes associated with both subjects and objects, and a “time interval access graph.” The time interval access graph is used to define constraints on the temporal relations between subjects and objects. Interval algebra is used to define and analyze the...
