چکیده

هدف پژوهش حاضر طراحی سیستم استنتاج فازی برای ارزیابی زنجیره تأمین سبز شرکت­‌های تولیدی صادراتی است. این پژوهش از نظر هدف، کاربردی می‌­باشد. جامعه آماری پژوهش شامل شرکت­‌های تولیدی صادراتی در شمال­‌غرب کشور است که نمونه آماری به­‌صورت هدفمند و به تعداد 143 شرکت تعیین شد. برای جمع­‌آوری داده­‌ها از پرسشنامه پژوهشگر­ساخته مبتنی بر مبانی نظری پژوهش استفاده شد. برای بررسی روایی پرسشنامه از روایی سازه بر اساس تحلیل عاملی تأییدی بهره­گیری شد. برای بررسی پایایی پرسشنامه نیز از ضریب آلفای کرونباخ استفاده شده است. پرسشنامه­‌های پژوهش، پس از تأیید روایی و پایایی در میان اعضای نمونه آماری پژوهش توزیع شد. به­‌منظور ارزیابی زنجیره تأمین سبز شرکت‌ها از سیستم استنتاج فازی، بر اساس توابع عضویت مثلثی و استنتاج ممدانی، بهره گرفته شده است. نتایج نشان می‌­دهد که سیستم طراحی­‌شده قادر است میزان سبز­بودن زنجیره تأمین شرکت‌های صادراتی را بر اساس مقادیر عددی و واژه‌­های زبانی نشان دهد.

چکیده [English]

This paper aims to design a fuzzy inference system to evaluate the green supply chain of export manufacturing companies. This research has been applied from the point of view of purpose. The statistical population of this study included export manufacturing companies in the northwest of the country. The statistical sample is targeted, and 143 companies are determined. A research questionnaire based on the research literature was used to collect the data. In order to examine the validity of the questionnaire, while using formal validity, the validity of the structure has been used based on confirmatory factor analysis. Cronbach's alpha coefficient was also used to evaluate the reliability of the questionnaire. The research questionnaires were distributed among the statistical sample members of the research after confirming the validity and reliability. In order to evaluate the green supply chain of companies, a fuzzy inference system has been used based on triangular membership functions and Mamdani inference. The results show that the designed system is able to show how green the supply chain of companies is based on numerical values ​​and linguistic terms.
