چکیده

امروزه توسعه فناوری و توجه به نوآوری باعث شده است ذائقه‏ی بازار به ویژه بازار مُد و پوشاک دستخوش تغییرات مداوم شود. در چنین بازارهایی خرده‌فروشان و تولیدکننده‏گان چابکی و انعطاف‏پذیری را به عنوان یکی از راهبردها در زنجیره تأمین خود مد نظر قرار داده‏اند. در این مقاله ابتدا یک مدل استکلبرگ دو-سطحی شامل خرده‏فروش و تولیدکننده که به‌صورت سنتی بر سر مقدار کالا و قیمت فروش آن باهم رقابت دارند ارائه شده است. سپس مدل دیگری با اضافه نمودن برخی از ویژگی‏های چابکی به مدل اول توسعه داده‌شده است. در این مدل علاوه بر در نظر گرفتن رقابت بین اعضای زنجیره تأمین، تأثیر رفتار مشتریان بر تصمیمات اعضای زنجیره تأمین نیز لحاظ شده است. هدف این مقاله ارائه راهکاری مناسب برای تعیین مقدار سفارش، مقدار تولید و قیمت با در نظر گرفتن شرایط رقابت، نیاز بازار و رفتار مشتریان برای حداکثر کردن سود تولیدکننده و خرده‌فروش و همچنین کاهش مقدار حراج می‌باشد. مدل استکلبرگ دو-سطحی ارائه‌شده ابتدا با رویکرد کاهن-تاکر تک‌-سطحی شده و کارایی مدل با یک مثال عددی بررسی و تحلیل شده است. نتایج مدل دوم نشان می‌دهد که خرده‌فروش و تولیدکننده با به‌کارگیری پاسخ‌دهی سریع و چابکی می‌توانند قیمت فروش را افزایش و مقدار حراج کالا در انتهای فصل فروش را کاهش دهند که در نهایت موجب افزایش سود هر دو عضو زنجیره تأمین ‌شده است.

چکیده [English]

Growths of technology and innovation have made continual changes in fashion business and costumer tastes. In situations like that, retailers and manufacturers select agility and flexibility as their main supply chain strategies. In this study, a bi-level model including the retailer and manufacturer who traditionally compete on the product quantity and price is proposed; then another model is developed by adding some characteristics of agility to first model. In the proposed model, in addition to the competition between the supply chain members, influences of the customers’ behavior on the decisions of supply chain members are considered. This study is aimed at proposing efficient solutions for determining the price and quantity of ordering and production, considering the situations of competition, customers and market toward maximization of the manufacturers’ and retailers’ profit. The proposed bi-level model is converted to a single-level one using the Karush-Kuhn-Tucker (KKT) and the results of the model are investigated and discussed by employing in a numerical example. Results show that the retailer and manufacturer, by making proper and precise decisions, can increase their sale price. Further, by improving their decisions, they can reduce the product clearance sale at the end of the sales season, which ends in the growth of profit for both of the supply chain members.
