چکیده

در این تحقیق یک مدل برنامه‌ریزی غیرخطی اعداد صحیح مختلط (MINLP) که به دلیل اتخاذ یک تابع هدف جامع غیرخطی است، پیشنهاد شده‌است. نتایج این تحقیق نشان می‌دهد که با استفاده از مدل‌های ریاضی می‌توان سناریوهای متنوعی را برای ارزیابی تاب‌آوری زنجیره تأمین در ابعاد مختلفی مانند فنی؛ هزینه و بازار و سازمانی طراحی کرد. این سناریوها به مدیران و تصمیم‌گیرندگان این امکان را می‌دهد که با شبیه‌سازی شرایط مختلف، نقاط ضعف و قوت زنجیره تأمین را شناسایی کرده و استراتژی‌های مؤثری برای بهبود تاب‌آوری اتخاذ کنند. با توجه به نتایج حاصل شده جمع مطلوبیت کل ایجاد شده از تخصیص سناریوها به هر ریسک برابر با 1442 و هزینه کل این تخصیص برابر با 41301 واحدپولی محاسبه شده است. این تحقیق نشان می‌دهد که طراحی سناریوهای تاب‌آوری زنجیره تأمین صنایع کنجدی نه تنها به بهبود کارایی و پایداری این صنایع کمک می‌کند، بلکه به تحقق اهداف توسعه پایدار و حفظ منابع طبیعی نیز نزدیک‌تر می‌شود.

چکیده [English]

In this paper a mixed integer nonlinear programming (MINLP) model, which is nonlinear due to the adoption of a comprehensive objective function, has been proposed. The results of this study show that using mathematical models, various scenarios can be designed to assess the resilience of the supply chain in various dimensions such as technical; cost; market; and organizational. These scenarios allow managers and decision makers to identify the strengths and weaknesses of the supply chain by simulating different conditions and adopt effective strategies to improve resilience. According to the results obtained, the total utility generated by assigning scenarios to each risk is calculated to be 1442 and the total cost of this allocation is 41301 monetary units. This research shows that designing supply chain resilience scenarios for sesame industries not only helps to improve the efficiency and sustainability of these industries, but also brings them closer to achieving the goals of sustainable development and conservation of natural resources.
