Performance evaluation has been developed in the form of management schools along by managerial thought development. Banks and financial institutes are one of the most important economic sections to each country which by receipts and payments directing and organizing facilitate business and commercial transactions and develop markets and economic growth and as the main pillars in directing and ...
یکی از مهمترین اهداف اجرای سیاستهای کلی اصل 44 قانون اساسی، ارتقاء کارایی واحدهای اقتصادی بوده است. این پژوهش با هدف ارزیابی میزان موفقیت دولت در ارتقای کارایی، 8 شرکت دولتی واگذار شده طی دهه 80 و در بازه زمانی دو سال قبل و دو سال بعد از واگذاری را مورد بررسی قرار می دهد. به منظور ارزیابی کارایی شرکتها از روش تحلیل پوششی دادهها (DEA) و مدلهای CCR و BCC خروجی محور اس...
In the history of DEA, there are two fundamental “Radial” and “Non-radial” approaches for the efficiency measurement. Each approach has its own advantageous and shortcomings. Avkiran et al. (2008) provided a unified framework, named Connected-SBM, for linking these approaches. In the present paper, first, based on the directional distance function we develop the Directional Slack-Based Measures...
This paper discusses returns to scale (RTS) in data envelopment analysis (DEA) for each of the presently available types of models. The BCC and CCR models are treated in input oriented forms while the multiplicative model is treated in output oriented form. (This distinction is not pertinent for the additive model which simultaneously maximizes outputs and minimizes inputs in the sense of a vec...
This chapter discusses returns to scale (RTS) in data envelopment analysis (DEA). The BCC and CCR models are treated in input oriented forms while the multiplicative model is treated in output oriented form. (This distinction is not pertinent for the additive model which simultaneously maximizes outputs and minimizes inputs in the sense of a vector optimization.) Quantitative estimates in the f...
This paper describes the DEA-based investment strategy for constructing of a stock portfolio in the Croatian stock market. The relative efficiency of the DMUs, which are in this case the selected stocks from Zagreb Stock Exchange, is obtained from the output oriented CCR and BCC models. The set of inputs consists of risk measures, namely return variance, Value at Risk (VaR) and beta coefficient...
در این مقاله فرایند نتایج تحقیق ارائه شده است که طی آن با استفاده از روش dea کارایی فنی نهاد و کارایی مقیاس 20 ایستگاه تقویت فشار گاز طی سال های 1390 تا 1391 مورد ارزیابی قرار گرفته است. برای سنجش کارایی با توجه به اهداف تحقیق، از مدل های پوششی ccr و bcc با ماهیت ورودی محور استفاده شده است. نهاده ها و ستده ها با توجه به میزان تأثیر و اهمیت آنها در عملکرد ایستگاه ها مشخص شدند. نتایج تحقیق نشان ...
Purpose: The aim of the article was to learn and evaluate development U.S. milk market. Design/Approach/Methodology: study analyzed number dairy cows, yield production, import, export consumption products in USA. In analysis research results, tabular, graphic descriptive methods were used. Findings: United States (U.S.) farms used be most efficient world. average herd cow is 115 head America (U...
This study's aim is to evaluate the technical efficiency of Bangladesh's manufacturing industry. We utilized DEA analysis with selected three distinct models: CCR, BCC, and slack-based model. In this study, number firms, labour, salary/wages, industrial non-industrial cost are considered as inputs variables, gross output value set variable. Our found that Common efficient industries Manufacture...
