چکیده

در این مقاله یک زنجیره تامین دو سطحی شامل یک تولیدکننده و یک خرده­فروش در صنعت لوازم خانگی مورد مطالعه قرار گرفته است. هدف اصلی این مطالعه، بررسی فعالیت تحقیق و توسعه، قیمت­گذاری و تصمیمات موجودی در ساختارهای غیرمتمرکز و متمرکز می­باشد. به منظور دستیابی به مقادیر بهینه در ساختارهای غیرمتمرکز و متمرکز، یک الگوریتم ارائه شده است. سپس، یک قرارداد تاخیر در پرداخت به عنوان یک مکانیزم هماهنگی به منظور هماهنگی فعالیت تحقیق و توسعه، قیمت­گذاری و تصمیمات موجودی توسعه داده شده است. علاوه بر این، برای تقسیم سود اضافی حاصل از مدل هماهنگی بین اعضای زنجیره تامین، یک استراتژی تخصیص سود پیشنهاد شده است. نتایج حاصل نشان می­دهند که مدل هماهنگ نه تنها سودآوری زنجیره تامین سبز را در مقایسه با مدل غیر متمرکز افزایش می­دهد، بلکه سود همه اعضا زنجیره تامین را افزایش می دهد. همچنین، قرارداد پیشنهادی عملکرد زنجیره تامین سبز را از منظر زیست محیطی و اقتصادی بهبود می­بخشد.
