[ 1 ] - Network Data Envelopment Analysis Models For Measuring Efficiency Of a Four-Stage Supply Chain With Returned Outputs
In this paper using DEA technique, four-stage DEA model mooted in order to consider the situation in which returned products exist. Returned products are the inputs of the previous sub-processes that need to be reprocessed due to existence of flaws. Here, a supply chain with four stages as supplier, manufacture, distributor, and retailer with intermediate and return products has been considered...
[ 2 ] - Supplier Selection in Supply Chain Management by Data Envelopment Analysis
Nowadays, managing a supply chain is turned to be one of the fundamentals of business process. In doing so, investigating and analyzing each and every of the processes and selecting the best of each process is an important challenge for strategic managers. In this paper Data Envelopment Analysis (DEA) technique is used and a model is provided for selecting the best suppliers with flexible inpu...
[ 3 ] - Evaluating the efficiency and ranking of west Guilan municipalities of urban services section using data envelopment analysis (DEA)
Municipalities as well as any other organization have needed assessment and efficiency measurement to make better use of their limited resources and greater effectiveness. The aim of this study is to evaluate the efficiency of municipalities, determining efficient and inefficient municipalities using data envelopment analysis, and classifying the municipalities using Anderson Peterson technique...
[ 4 ] - ارزیابی کارایی سود در زنجیره تامین سه مرحله ای با خروجی های برگشت داده شده با تکنیک تحلیل پوششی داده ها
مدیریت زنجیره تامین برای مدیران سازمان های مختلف به منظور بهبود عملکرد آن سیستم ها یک امر حائز اهمیت است. از جمله موارد این مدیریت آنالیز، تحلیل، و بررسی هر یک از مراحل یک زنجیره تامین می باشد. ارزیابی یک زنجیره به صورت "جعبه سیاه" به منظور مدیریت آن نمی تواند اطلاعات دقیقی برای تعیین استراتژی و هدف گزاری ارایه دهد. لذا لزوم به استفاده از تکنولوژی‌ها و ابزارهای جدید جهت تحلیل کل زنجیره و هر ...
[ 5 ] - طراحی سیستم پشتیبانی تصمیم‌گیری برای پیش‌بینی موفقیت مراکز تحقیقاتی با کمک تحلیل ممیز در تحلیل پوششی داده‌ها
Relief research centers have an important place in promoting science and technology nationwide. On the other hand, given the limitations in allocating the funds and the facilities needed to establish these centers, it is important to decide on the selection of priority centers. In this decision-making process, several factors, such as requirements, priorities and strategies, capabilities, and b...
[ 6 ] - MULTI-OBJECTIVE LOCATION-ROUTING MODEL WITH MULTIPLE TRANSPORTATION MODES FOR DESIGNING RELIEF NETWORKS UNDER UNCERTAINTY
Natural disasters and crisis are inevitable and each year impose destructive effects on human as injuries and damage to property. In natural disasters and after the outbreak of the crisis, demand for logistical goods and services increase. Effective distribution of emergency aid could have a significant role in minimizing the damage and fatal accident. In this study, a three-level relief chain...
[ 7 ] - SBM extended model with nonlinear value data in data envelopment analysis with axiomatic approach
One of the important goals of banks as important economic enterprises of any country is to increase economic efficiency. One of the important goals of banks as important economic enterprises of any country is to increase economic efficiency. The classical approach to data envelopment analysis models takes into account the linear valuation function for all indicators. But linear valuation in man...
[ 8 ] - بهبود عملکرد واحدهای تصمیم‌گیرنده کارا با استفاده از روش تقاطع ابرصفحه‌های سازای مجموعه امکان تولید در تحلیل پوششی داده ها
تحلیل پوششی داده ها (DEA) یک تخمین‌گر است. این تخمین‌گر سعی می کند که یک ارتباط بین ورودی های متعدد و خروجی های متعدد و همچنین تکنولوژی تولید را تخمین بزند. DEA واحدهای تصمیم گیرنده (DMU) را به دو بخش واحدهای کارا و واحدهای ناکارا تقسیم بندی می‌کند. در این صورت واحدهای کارا مرجعی برای واحدهای ناکارا خواهد بود. در مدل‌های سنتیDEA بهبود کارایی تنها برای واحدهای ناکارا صورت می گیرد و واحدهای کارا ...
[ 9 ] - Estimation of cost efficiency for firms in different technologies using data envelopment analysis
Data envelopment analysis (DEA) is a method for evaluating the relative efficiency of a set of firms in a production process. Estimation of cost efficiency is one of the branches of performance evaluation. Cost efficiency evaluates the ability of producing current output with minimum available cost. Now let's assume that there are several groups of firms that operate separately and have differe...
