چکیده

در سیستم کنترل موجودی کلاسیک، درآمد فروش محصول در لحظه تحویل کالا فوراً دریافت می‌شود و کالاها می­ توانند عمر نامحدود داشته باشند؛ اما در دنیای واقعی کالاهایی وجود دارند که به مرور زمان بر اثر به ­وجود­آمدن فناوری جدید ارزش خود را از دست می دهند که به­ عنوان کالاهای منسوخ­ شدنی شناخته می­ شوند. همچنین برای ترغیب خریدار، فروشنده می ­تواند به خریدار این اجازه را بدهد تا هزینه خرید را با تأخیر پرداخت کند. در این پژوهش یک مسئله کنترل موجودی منسوخ­ شدنی با سیاست پرداخت معوقه در شرایط تورمی با هدف دستیابی به حداقل هزینه بررسی خواهد شد. نتایج عددی نیز در یک مطالعه موردی واقعی صنعت خرده ­فروشی تلفن همراه ارائه شده است. نتایج نشان می ­دهد با کاهش دوره منسوخ­ شدن با توجه به اینکه ریسک منسوخ ­شدن کالا افزایش می­ یابد، مقدار سفارش­ بهینه کاهش می ­یابد نتایج حاکی از آن است که استفاده ترکیبی از سیاست­ های مدیریت موجودی با در­نظر­گرفتن تأخیر در پرداخت باعث کاهش هزینه ­های موجودی می ­شود.
