[ 1 ] - Efficient DMUs improvement based on input expenses reduction using data envelopment analysis

Network nowadays, the main purpose in the models designed by Data Envelopment Analysis (DEA), is to improve the outputs. In this method which is expressed by Khodabakhshi, with an output oriented BCC model, the output increases when the input increases. In this article we will discuss the efficient Decision Making Units (DMUs) in the input oriented BCC model to reduce the input expenses signifi...

[ 2 ] - تخصیص منصفانه هزینه ثابت داده های مقیاس بازه ای و مقیاس کسری بین واحد های تصمیم گیرنده در تحلیل پوششی داده ها

In recent years, fair allocation of resources or fixed costs in DEA have been noticed by researches, in which the main objective is unchanging efficiency of decision making units, In which the main purpose is to not change the efficiency of decision-making units before and after the allocation of costs. On the other hand, all studies have been due to the fraction-scale data, and any special att...

[ 3 ] - An Approximation Method for Fuzzy Fixed-Charge Transportation Problem

In this paper, we develop the fuzzy fixed charge transportation problem when the costs are the fuzzy numbers. The first step it transform into the classical fuzzy transportation problem. The next, we obtain the best approximation fuzzy on the optimal value of the fuzzy fixed-charge transportation problem. This method obtains a lower and upper bounds both on the fuzzy optimal value of the fuzzy ...

[ 4 ] - ارائه مدل بودجه‌ریزی در تحلیل پوششی داده‌ها بر اساس ارزیابی عملکرد واحدهای تصمیم‌گیری

تحلیل پوششی داده‌ها یکی از تکنیک‌های ارزیابی عملکرد واحدهای تصمیم‌گیری می‌باشد. این تکنیک علاوه بر ارزیابی، توانمندی‌های بسیاری در حوزه مدیریت و اقتصاد دارد. تخصیص منابع یکی از این توانایی‌های جالبی است که به وسیله مدل‌های تحلیل پوششی داده‌ها قابل اجرا است. از آنجایی که بودجه به عنوان یک منبع درنظر گرفته می‌شود، با استفاده از روش‌های تخصیص منابع می‌توان بودجه‌ریزی را نیز انجام داد. در این تحقیق...

[ 5 ] - Generalization of Dynamic Two Stage Models in DEA: An Application in Saderat Bank

Dynamic network data envelopment analysis (DNDEA) has attracted a lot of attention in recent years. On one hand the available models in DNDEA evaluating the performance of a DMU with interrelated processes during specified multiple periods but on the other hand they can only measure the efficiency of dynamic network structure when a supply chain structure present. For example, in the banking in...
