چکیده

کی از تصمیمات کلیدی در سازمان‌ها، انتخاب ‌تامین‌کننده می‌باشد. معمولا فهرستی از تامین‌کنندگان شناسایی شده برمبنای مجموعه‌ای از شاخص ها، ارزیابی ‌می شوند، که این موضوع نشان از یک مسئله تصمیم‌گیری چندمعیاره است. روش‌های متعدد و شاخص‌های چندگانه‌ای برای ارزیابی تامین‌کنندگان وجود دارد. ماهیت چنین تصمیم‌گیری‌هایی در شرایط عدم اطمینان پیچیده است. هدف این پژوهش ارائه روشی برای ارزیابی تامین کنندگان در شرایط عدم اطمینان است. در این تحقیق شاخص های ارزیابی از ماتریس بالقوه تامین کنندگان استخراج و پس از تعیین اهمیت شاخص‌ها با استفاده از روش بهترین-بدترین، درجه عدم اطمینان با تحلیل رابطه‌ای خاکستری محاسبه و در نهایت برای رتبه‌بندی تامین‌کنندگان از روش دمپستر شافر استفاده شده است. داده های تحقیق از خبرگان صنعت سخت افزار، که از دانش و سابقه کافی در حوزه خرید و تدارکات برخوردار بوده، جمع آوری شده است. یک مطالعه موردی واقعی برای نشان دادن رویکرد ترکیبی پیشنهاد داده شده برای انتخاب تامین کننده ارائه شده است. در بعد توانمندی، شاخص‌های کیفیت و ظرفیت انبار و در بعد تمایل، شاخص‌های تمایل به نشر اطلاعات وتوافق متقابل به ترتیب مهمترین و کم اهمیت ترین شاخص می باشند. در نهایت رتبه بندی تامین کنندگان در شرایط عدم اطمینان انجام شد. در یافته های تحقیق شاخص های ارائه شده عمومی بوده و می تواند در صنایع و شرایط مختلف مورد استفاده قرار گیرد. همچنین از تحلیل رابطه ای خاکستری جهت محاسبات عدم اطمینان استفاده شده است.

چکیده [English]

One of the key decisions in organizations is the selection of suppliers. Typically, a list of identified suppliers is evaluated based on a set of criteria, which indicates a multi-criteria decision-making problem. There are multiple methods and multiple criteria for evaluating suppliers. The nature of such decisions is complex in conditions of uncertainty. The purpose of this study is to provide a method for evaluating suppliers in conditions of uncertainty. In this research, evaluation criteria are extracted from the supplier potential matrix, and after determining the importance of criteria using the Best-Worst Method, the degree of uncertainty is calculated with Gray Relational analysis and finally, Dempster-Shafer method is used to rank suppliers. Research data has been gathered from hardware industry experts, with knowledge and experience in purchasing and procurement. A real case study is presented to illustrate the proposed hybrid approach to supplier selection. In the capability dimension, quality and capacity of the warehouse and in the willingness dimension, willingness to share information and mutual interaction are respectively the best and worst indicators. Also, the ranking of suppliers was conducted in conditions of uncertainty. Research results are important from a few perspectives. First, the criteria presented are public and can be used in different industries and conditions. Second, gray relational analysis is used to calculate uncertainty, which is due to the use of less data.
