چکیده

است. این پدیده بر افزایش نوسانات تقاضا به » اثر شلاقی « یکی از دلایل ناکارآمدی زنجیره های تأمین
سمت بالای زنجیره اشاره دارد. مدیران زنجیره، تأمین این افزایش نوسانات را در سطوح موجودی و
سفارشات تجربه می کنند. از طرفی، کاهش نوسان در سفارشات ممکن است به علت افزایش در واریانس
موجودی، اثر منفی بر سطح خدمت به مشتری داشته باشد. بنابراین، در این نوشتار قصد داریم در یک
زنجیرة تأمین س هسطحی شامل یک خرده فروش، یک عمده فروش و یک تولیدکننده با 2 حالت متمرکز و
غیرمتمرکز، با توجه به دلایل اثر شلاقی به تخمین توابع اثر شلاقی و ذخیره موجودی با استفاده از
روش شناسی سطح پاسخ بپردازیم، و نشان دهیم که باتوجه به اهمیت زیاد دلایل اثر شلاقی و تعاملات بین
آن ها م یتوان درصدهای بهینة دلایل و تعاملات بین آن ها و میزان مطلوبیت اثر شلاقی و ذخیرة موجودی را
درغالب یک مدل ارائه نمود.

چکیده [English]

A major cause of supply chain deficiencies is the bullwhip effect. This phenomenon refers to demand variability increases as one move up the supply chain. Supply chain managers experience this variance amplification in both inventory levels and orders. Other side, dampening variability in orders may have a negative impact on customer service due to increase in inventory variance. The contribution of this paper is the estimation of the bullwhip effect and stock functions with using of response surface method under causes of the bullwhip effect in a three stage supply chains consisting of a single retailer, single wholesaler and single manufacturer with both centralized and un-centralized chains and show that with Considering the importance of the bullwhip effect reasons and interactions between them, the percent of optimal reasons and interactions between them and the level of desirability of bullwhip effect and net Stock will be illustrated by a model
