Recently, a mixed integer data envelopment analysis (DEA) model has been proposed to find the most BCC-efficient (or the best) decision making unit (DMU) by Toloo (2012). This paper shows that the model may be infeasible in some cases, and when the model is feasible, it may fail to identify the most efficient DMU, correctly. We develop an improved model to find the most BCC-efficient DMU that r...
In order to set up a framework dedicated to the transformation of Digital Mock-Ups (DMUs) into simulation models, this paper exposes the problematic of simulation assembly model preparation. It analyses the differences between standalone component and assembly preparations to justify the reasons of time consuming tasks specific to assemblies. To this end, the content of a DMU is analyzed to exp...

However, DEA does not provide more information about the efficient DMUs. In this research, the ...
Abstract Conventional models of data envelopment analysis (DEA) are based on the constant and variable returns-to-scale production technologies. Any optimal input output weights multiplier DEA these technologies interpreted as being most favorable for decision making unit (DMU) under assessment when latter is benchmarked against set all observed DMUs. In this paper we consider a very large clas...
در مدلهای کلاسیک تحلیل پوششی دادهها (مثل مدلهای CCR و BCC)،این فرض وجود دارد که مقدار عددی دقیقی برای ورودیها و خروجیها مشخص است. ولی بسیاری از اوقات در شرایط واقعی کسب و کار، تعیین مقدار عددی دقیق برای برخی ورودیها و یا خروجیها امکانپذیر نیست. در این مقاله، یک مدل نوین تحلیل پوششی دادهها ارائه میشود که کاربر را قادر میکند تا کاراترین واحد تصمیمگیری را با در نظر گرفتن دادههای غیردقی...
Efficiency is the main issue in any data envelopment analysis. Realizing output by a minimum of input or reaching maximum given credo, scale effects often are only sort accessory. In modern economics play prominent role, however. What right size decision making unit (DMU) and how to proceed there. Returns inform DMU about its hitherto disregard show way towards ideal activity size. Combining ef...
A fundamental weakness of the Data Envelopment Analysis (DEA) is its weak discrimination in cases when a small number of decision making units are compared. Therefore, in such cases the basic DEA model (optimistic and pessimistic) is used in combination with other methods or additional constraints are added to the model. In this paper, the cross-efficiency method was combined with a self-rankin...
This paper clarifies the connection between multiple criteria decision-making and decision under uncertainty in a qualitative setting relying on a finite value scale. While their mathematical formulations are very similar, the underlying assumptions differ and the latter problem turns out to be a special case of the former. Sugeno integrals are very general aggregation operations that can repre...
