چکیده

امروزه زنجیره تامین و بررسی هزینه های آن از اهمیت بسیاری برخوردار است. تعداد سطوح زنجیره تامین و چگونگی ساختار روابط بین این سطوح می تواند نقش مهمی در عملکرد بهینه‌ی یک زنجیره تامین داشته باشد. ا لذا در این تحقیق، سعی شده است با ارئه یک مدل چند هدفه در کنار بیشینه سازی سود، کیفیت محصولات جابجا شده در طول زنجیره حداکثر گردد و زمان نحویل نهایی حداقل گردد. پس از ارائه‌ی مدل مذکور، در ادامه به حل قطعی مدل تحت نرم افزار بهینه ساز گمز و حل غیرقطعی آن با الگوریتم های فرا ابتکاریNSGAII و MOIWO تحت نرم افزار متلب پرداخته شده است و نتایج حاصل از حل مساله با این دو روش با یکدیگر مقایسه شده اند. این نتایج نشان می دهد، الگوریتم فراابتکاری MOIWO در همه ی شاخص ها به جز شاخصNPS، از الگوریتم فراابتکاریNSGAll برتر است.

چکیده [English]

Today, the supply chain and evaluating its costs are of great significance. The number of layers of the supply chain and the structure of the interactions between these layers can play an important role in achieving the optimal performance of the supply chain. Besides, it is undeniable that service provision and product transportation from a chain layer to the next one do not take the same amount of time because due to different reasons such as transportation challenges, there would always be the possibility that transportation doesn’t go as planned.  Therefore, by proposing a multi-purpose model, this study seeks to maximize the profit and the quality of the products transported through the supply chain, as well as minimizing the total delivery time.  After presenting the model, it is solved by applying deterministic algorithms using GAMS software, and also NSGAII and MOIWO non-deterministic meta-heuristic algorithms using proper software. Then, these two solutions are compared with each other. Results indicate that MOIWO meta-heuristic algorithm is superior to NSGAII in all indicators except for the NPS indicator.
