Abstract

زنجیره تامین صنعت فولاد به روش احیای مستقیم، شامل تهیه سنگ آهن، تولید کنسانتره، گندله، آهن اسفنجی و فولاد است. محدودیت تأمین ‌کنندگان، تنوع نهاده‌های مصرفی و محدودیت مشتریان باعث تنوع گزینه‌های فنی و اقتصادی شده که مدیریت بهینه زنجیره تامین را ضروری می‌سازد. هدف پژوهش حاضر، ارایه مدل پویای زنجیره تامین دوسطحی (سنگ آهن-کنسانتره و کنسانتره-گندله) با استفاده از رویکرد پویایی‌های سیستم است. بدین منظور، ضمن شناسایی متغیرهای کمی و کیفی و تعیین روابط بین آنها، چگونگی تعامل و نحوه بازخورد بین متغیرها تعیین گردید. در ادامه یک مدل شبیه‌سازی طراحی و امکان بررسی سناریوهای مختلف تولید فراهم گردید. جهت بررسی کارکرد مدل، از داده‌های یک مجتمع تولید فولاد در ایران استفاده شد. بر این اساس، افزایش 2% عیار سنگ آهن منجر به افزایش 35/3% در تولید نهایی گندله و افزایش همزمان 2% عیار سنگ‌آهن ورودی، 5% نرخ تولید و 2% بازیابی باعث افزایش 85/5% در تولید گندله می‌شود
