ملخص المقالة :
در این مقاله برای دستیابی به حداکثر سود حاصل از فروش محصولات فسادپذیر سیاست کاهش قیمت یا تخفیف به کار گرفته شده است. به دلیل اینکه محصولات فسادپذیر پس از یک بازه زمانی دچار افت کیفیت شده و فساد در آنها شکل می‌گیرد ، بنابراین نزد مشتری از جذابیت لازم برخوردار نیستند و تقاضا برای خرید این محصولات کاهش می یابد، با سیاست کاهش قیمت می توان تقاضا را افزایش داد همچنین با بالارفتن میزان فروش، ضایعات نیز کاهش خواهد یافت و کاهش هزینه خواهیم داشت ؛بنابراین سود کل افزایش خواهد یافت. حال مسأله اینست که اگر تخفیف در زمان مناسب و مقدار بهینه ارائه نشود به هدف رسیدن به حداکثر سود نخواهیم رسید. لذا، در این مقاله به دنبال تعیین زمان بهینه تخفیف و مقدار بهینه تخفیف هستیم با هدف ماکزیمم کردن سود کل بنگاه مفروضات این مقاله تابع تقاضا وابسته به دو عامل قیمت فروش و موجودی در معرض نمایش، سطح موجودی نهایی غیر صفر و نرخ فساد ثابت می باشد. پس از حل مدل از رویکرد دقیق و مثال عددی، مثال با استفاده از الگوریتم ژنتیک، الگوریتم تبرید شبیه‌سازی‌شده حل شده و نتایج مقایسه شد و سپس تحلیل حساسیت پارامترهای اصلی سیستم انجام گردید.
