        In today’s competitive environment in manufacturing and services process, the organizations are confronted with the need to have indicators and patterns for assessing the performance. The balanced scorecard is a successful instrument in implementing the strategic plans of the organization. The present paper aims to evaluate the performance and rank the branches of Tejarat bank in Yazd province based on their efficiency. The balanced scorecard is an appropriate device for designing and measuring the performance in terms of four perspectives including financial, customer, internal process and growth and innovation. This study also intends to use a combining model of BSC and fuzzy data envelopment analysis to evaluate the performance of the branches. This is a descriptive study using field study along with the library, observation and sometimes interview to gather the required information. The findings reveal that among the twenty-six examined branches, 11 branches are efficient. Additionally, the cross efficiency ranking has been used to rank the branches. Finally, the sensitivity analyses demonstrate that ATM has the highest impact on the efficiency of the units followed by the position and the number of employees. On the other hand, the total bank deposits have the least impact on the efficiency of the banks. Manuscript profile

        This paper studies the congestion model development in fuzzy data envelopment analysis. To obtain the lower and upper bounds for concepts of efficiency and inputs and outputs, it is possible to apply the advantages of α-cut which exists in fuzzy data envelopment analysis. Additionally, this paper proposes a new concept of congestion which examines congestion from an optimistic and pessimistic viewpoint. In this concept, the optimistic case examines congestion in a condition that the under-investigation decision making unit provides the optimum output by taking the lowest input. The pessimistic case, also, demonstrates a condition in which the under-investigation decision making unit provides the worst output by taking the optimum input. Using these two cases, the congestion is studied in fuzzy data envelopment analysis.Keywords: Data envelopment analysis, fuzzy data envelopment analysis, optimistic and pessimistic congestion, α-cut.

        This paper aims to investigate the relationship between Organizational Culture and Knowledge Utilitization and Application for ranking non-financial performance of Department of Sahand Tire Company. The main purpose of the study is presenting a model for improvement of non-financial performance of the department and studying the effect of organizational culture on non-financial performance with the mediating role of knowledge utilitization and application by using slack-based fuzzy network data envelopment analysis (FNDEA) on the basis of excess of inputs and shortage of outputs. The related data were collected by a questionnaire distributed among 117 personnel from 12 units on the basis of random-classified sampling. The findings showed that the non-financial performance of workshop and manufacturing Process are better than the performance of other units. Also, findings showed that knowledge utilitization and application factor has a significant and positive role in the relationship between organizational culture and non-financial performance.

        This paper introduces a method to find the optimal solution of technology selection model with fuzzy data. The paper suggests a simple computational method to obtain the optimal solution of fuzzy linear programming (LP) problem used in technology selection without the need for solving any fuzzy LP. Clearly the contribution of this research is that it reduces the fuzzy computational complexity, which is significant when dealing with more complex computations.   Manuscript profile

        6 - پیاده‌سازی DEA فازی درون مدل PEM جهت ارزیابی عملکرد سازمان‌های پروژه‌محور: یک مطالعۀ موردی

        سازمان های پروژه محور در صنایع بالادستی سهم زیادی از منابع ملی را در اختیار دارند و نقش مهمی در توسعه یک کشور ایفا می کنند. ارزیابی عملکرد سازمان های پروژه محور می تواند به مدیران کمک کند تا از ورودی ها به طور موثر استفاده کنند و راه خود را برای دستیابی به اهداف هموار ک More
        سازمان های پروژه محور در صنایع بالادستی سهم زیادی از منابع ملی را در اختیار دارند و نقش مهمی در توسعه یک کشور ایفا می کنند. ارزیابی عملکرد سازمان های پروژه محور می تواند به مدیران کمک کند تا از ورودی ها به طور موثر استفاده کنند و راه خود را برای دستیابی به اهداف هموار کنند. برای ارزیابی عملکرد سازمان های پروژه محور، شاخص های کمی و کیفی زیادی وجود دارد. محاسبه کارایی از طریق تحلیل پوششی داده ها (DEA) یک شاخص رایج برای ارزیابی عملکرد در چنین شرکت هایی است. در مدل سنتی DEA داده‌های واضح مورد نیاز است در حالی که در دنیای واقعی، بیشتر داده‌ها نادقیق و نامطمئن هستند. یکی از دلایل اصلی عدم قطعیت مربوط به اطلاعات غیر کمی، ناقص و دست نیافتنی است که باعث ادغام منطق فازی و مجموعه های فازی در مدل های مختلف مانند DEA می شود.ایدۀ اصلی پژوهش حاضر ترکیب رویکردهای کمی و کیفی در ارزیابی عملکرد برای بهره‌گیری از هر دو و دستیابی به نتایج دقیق‌تر است. از این رو، در این مقاله، یک مدل ترکیبی مبتنی بر تحلیل پوششی داده های فازی (FDEA) و مدل تعالی پروژه (PEM) برای ارزیابی عملکرد در سازمان های پروژه محور پیشنهاد شده است. ابتدا ارزیابی عملکرد توسط مدل PEM داده های فازی انجام می شود. سپس پیاده سازی فازی DEA در مدل PEM انجام می شود که در آن ورودی ها و خروجی های مدل FDEA معیارهای مدل PEM هستند. مدل هیبریدی پیشنهادی برای ارزیابی 30 شرکت پتروشیمی در ایران استفاده شده است. مقایسه نتایج هر دو مدل نشان‌دهنده ضریب همبستگی تقریباً 90/0 در سطح معنی‌داری 01/0 است که نشان‌دهنده همبستگی مناسب بین دو مدل است.

        Existence of appropriate business environment and need assessment of factors affecting it to improve national production process and creating new economic capacities is undeniable. The purpose of this study is measuring and ranking the easiness of efficiency of business in upward middle-income countries over a four-year period (2017-2020). For this purpose, 63 middle-income countries were evaluated with fuzzy dynamic multi-objective data envelopment analysis techniques in 10 areas of starting a business, obtaining construction license, cost of energy(electricity), registered property, obtaining credit, protecting minority Investors, paying taxes, cross-border trade, enforcing contracts and bankruptcy. The results showed that there is great potential for increasing efficiency and productivity in all inputs, the success of doing business in different countries is largely influenced by factors such as starting a business, cross-border trading, receiving electricity and supporting minority investors. Guatemala has been ranked one as the best performance in ease of businesses in 2019 and 2020, according to research findings while Iceland's has the worst rankings in 2018 and 2019, and Iran ranked 51st, following an improving trend in 2020 with 29 steps down Manuscript profile
