چکیده

در این مقاله یک مدل موجودی برای اقلام فاسد شدنی با فرض برقراری یک اعتبار تجاری دو سطحی در نظر گرفته می‌شود؛ یعنی نه فقط خرده‌فروش از مزایای تأخیر در بازپرداخت از جانب تأمین‌کننده بهره می‌برد بلکه به مشتریان خود نیز دوره اعتباری پیشنهاد می‌دهد. نرخ تقاضای اقلام تابع خطی از سطح موجودی خرده‌فروشی فرض شده است. ارزش زمانی پول و اثر تورم نیز در نظر گرفته شده است و اقلام به‌ محض اینکه به موجودی تبدیل می‌شوند شروع به فاسد شدن می‌نمایند. نخست مدل ریاضی مسئله توسعه داده شده و پس از آن شیوه بهینه‌سازی در قالب یک مثال ارائه شده است.

Optimal Economic Ordering Policy for Deteriorating Items under Two-level Trade Credit and Inflation

چکیده [English]

In this paper, we develop an inventory model with delay in payments for deteriorating items. In our model, retailer who purchases the items enjoys a fixed credit period offered by his/her supplier and, in turn, also offers a credit period to his/her customers in order to promote the market competition. The demand is assumed to be linear function of the retailer's current-stock level. The effect of both inflation and time value of money are taken into account. The items start deteriorating from the moment they are put into the inventory. The mathematical model is developed and numerical example is presented to illustrate optimization
