چکیده مقاله :
هدف این پژوهش طراحی و توسعه یک مدل برای انتخاب تأمین کننده مناسب با استفاده از رویکردهای مدل معادلات ساختاری و منطق فازی در شرکت فولاد خوزستان بود. جامعه آماری این تحقیق کلیه کارکنان مرتبط با ارزیابی و انتخاب تأمین کنندگان در شرکت فولاد را تشکیل می دهد، که 200 نفر بودند. روش نمونه گیری این تحقیق نمونه گیری در دسترس است. ابزارهای جمع آوری اطلاعات فرم پرسشنامه است؛ که دو پرسشنامه برای دو سطح انتخاب تأمین کننده تهیه گردیده است. روشی جامع یک روش دو سطحی از رویکرد مدل معادلات ساختاری و رویکرد منطق فازی ارائه شده است.. به منظور تجزیه و تحلیل داده ها از نرم افزار Lisrel ،SPSS و Matlab استفاده گردید. پس از مرور ادبیات و با توجه به نظرات کارشناسان کارخانه فولاد خوزستان 8 معیار شامل سطح بالای کیفیت، عملکرد تحویل تامین کننده، سطح معیار خدمات، سطح هزینه و قیمت، سطح بالای معیار مدیریتو سازمان، موقعیت مالی، سطح تکنولوژی و توانمندیهای فنی و اعتبار و سابقه تأمین کننده برای ارزیابی و انتخاب تأمین کننده شناسایی گردید. بعد از تحلیل نتایج تحقیق نشان داد که هشت معیار مشخص شده به طور معنی داری بر انتخاب تأمین کننده تاثیر دارند. همچنین مطابق یافته ها پس از تایید برازش و مناسب بودن مدل اندازه گیری انتخاب تأمین کننده و تعیین وزن و اهمیت نسبی معیارهای تحقیق در سطح اول و تعیین جایگاه گزینه های انتخاب شرکت فولاد خوزستان برای تعیین تأمین کننده قطعات آلیاژی شرکت در سطح دوم و تایید سازگار بودن و صحت این تصمیمات ترکیب نتایج و خروجی نهایی مدل پیشنهادی تحقیق نشان داد که تأمین کننده A با توجه به نمرات محاسبه شده، دارای بیشترین میزان اهمیت و بالاترین رتبه و در نتیجه بهترین گزینه برای شرکت فولاد خوزستان برای تهیه قطعات آلیاژی است. پس از آن به ترتیب تأمین کننده های D ، C و B در رتبه های بعدی قرار می گیرند.
This study was performed in Khoozestan Steel Company for the development of a model for strategic supplier selection approaches using structural equation modeling and fuzzy logic .The purpose of this research was to design and develop a suitable model for supplier selection using structural equation modeling and fuzzy logic approaches in the Khoozestan Steel Company. Survey was done across all employees associated with the evaluation and selection of suppliers of the steel company, which had a total of about 200 people. Sampling method of this study is sampling available. Questionnaire used as a data collection tool, and for this research two questionnaires prepared to provide two levels of selection A comprehensive approach inclusive two-level structural equation modeling and fuzzy logic approach is proposed. SPSS, Lisrel and Matlab softwares were used for data analysis. After reviewing the literature and views of the experts of Khoozestan Steel, 8 criteria have been identified including high quality, Supplier delivery performance, service standard level, the cost and pricing level, high standard of management and organization, financial status, level of technology and technical capabilities and experience in providing funding for supplier evaluation and selection. After analysis, the results of the study showed that eight specified criteria have significant impact on the choice of supplier. The findings also confirmed the fitness and suitability of the supplier selection model and determination of the relative importance of research in the first level and position options for the Khoozestan Steel Company for determination of the supplier of alloy components at the second level and confirmation of compatibility and validity of decisions and final output of the proposed model showed that the scores are calculated. The highest of the A supplier has the most importantce and highest rank, and therefore the best option for Khoozestan Steel Company for supplying the alloy components. After A supplier, the suppliers of C, D and B are next in rank respectively.
