چکیده

انتخاب تأمین‌کننده به‎عنوان یکی از مسائل مهم در حوزۀ تصمیم‌گیری، همواره یکی از دغدغه‌های اصلی مدیران ارشد در این حوزه بوده است. ماهیت چنین تصمیم‌گیری‌هایی معمولاً پیچیده است. این پژوهش در نظر دارد در شرایط عدم قطعیت با استفاده از تصمیم‌گیری چند معیاره و تئوری اعداد خاکستری رویکرد جدیدی برای انتخاب تجهیزات مناسب با معیارهای تعریف شده ارائه دهد. روش پیشنهادی در این تحقیق، استفاده از روش بولزای برای وزن‌دهی و رتبه‌بندی است. در روش پیشنهاد شده، پس از تعیین وزن معیارها و تشکیل ماتریس تصمیم‌گیری خاکستری، در مرحلۀ رتبه‌بندی گزینه‌ها سه روش حل ارائه می‌شود. این روش با توجه به یکپارچگی و به دلیل در اختیار قرار دادن سه شاخص برای راستی آزمایی نتایج، می‎تواند در رویکرد تصمیم‎گیری‌های چند معیاره در شرایط عدم اطمینان مفید واقع شود. نتایج این پژوهش نیز نشان می‌دهد این رویکرد توانایی و کارایی مناسبی برای انتخاب دقیق‌تر تأمین‌کننده و همچنین کاهش قضاوت‌های انسانی برای وزن‌دهی به معیارها و انطباق نتایج حاصل از رویکرد پیشنهادی با بازخوردهای واقعی دارد.

چکیده [English]

The selection of suppliers, equipment and machinery in the industrial and services sectors has always been one of the main concerns of senior managers in the field. Such decisions are usually complex nature and has many models and methods for decision-making for the selection of equipment and suppliers have been proposed. This study intends in conditions of uncertainty using MCDM and gray number theory a new approach to the selection of equipment and machinery is suitable with criteria defined offer.
For this purpose, the proposed method Bulls-eye , Bulls-eye based on gray numbers at the same time for weighting and ranking criteria to select options for buying the things (study of hospital equipment) used. This framework is based on the integrity and accuracy and most importantly Provides three index for the verification of the results of Multi-Criteria Decision Making under Uncertainty helpful. The results also show such an approach can be a good performance compared to reduce the complexity of computing And the applicability of the results of the proposed approach have real feedback
