چکیده

این مقاله مدل موجودی سه‌سطحی (یک تأمین­کننده-یک توزیع­کننده-یک مشتری) دارای محصول ناقص را توسعه داده است که تأمین­کننده مقدار سفارش را برای توزیع­کننده ارسال می­کند و توزیع‌کننده این محصولات را بازرسی می­کند. در این مدل موجودی دارای محصولات ناقص فرض می‌شود که (الف) بازرس در عملیات بازرسی دچار خطا می­شود، (ب) پرداخت اعتباری دوسطحی درنظر گرفته شده است که در آن مشتریان ابتدا براساس پیشینه خرید به دو دسته جدید و قدیم تقسیم‌بندی شده­اند. براین اساس پرداخت اعتباری به‌صورت کامل به مشتریان قدیمی و به‌صورت جزئی به مشتریان جدید ارائه شده است، (ج) مشتریان جدید براساس پرداخت هزینه­های خرید، در دو گروه خوش­حساب و بدحساب قرار داده شده­اند و مشتریان بدحساب آن‌هایی هستند که از پرداخت قیمت محصول خریداری شده پس از اتمام دوره پرداخت اعتباری، امتناع می‌نمایند، و (د) تقاضا به دفعات تبلیغات وابسته است. در این تحقیق پنج مورد فرعی براساس رابطه دوره‌های اعتباری تأمین‌کننده به توزیع‌کننده بررسی شده و برای هریک تعداد بهینه دفعات تبلیغات و طول دوره سفارش بهینه تعیین شده است. به‌علاوه مدل ارائه شده با داده‌های مدل پایه مقایسه شده و سپس با داده­هایی واقعی مطالعه موردی حل شده است. نتایج تحلیل حساسیت این مجموعه داده واقعی نشان داد که درصد محصولات ناقص، خطاهای بازرسی تأثیر قابل توجهی بر میزان تابع سودآوری دارند. نهایتاً براین اساس، دستاوردهای مدیریتی و پیشنهادهایی برای مطالعات آینده ارائه شده است.

چکیده [English]

This article has developed a three-level (single supplier-single distributor-single customer) inventory model with defective products in which the supplier delivers the distributor’s ordering quantity and the distributor inspects the finished products. In this inventory model in which order includes some imperfect products, it is assume that (a) Inspectors make mistakes during the inspection process. (b) Two-level credit payment is considered to the customers, in which customers are first divided into new and old categories. Accordingly, trade credit is assigned fully to old customers and partially to new customers. (c) New customers are also divided into well-accounted and bad accounted customers in which bad accounted customers are those who refuse to pay the price of purchased finished products after ending the credit payment period. (d) Demand is dependent on number of advertisements. In this research, five subcase problems have been investigated based on the trade credit relation of supplier and distributor and for each case, the optimal number of promotional efforts and optimal length of the order cycle have been determined. In addition, the proposed model has numerically compared with the basic model and then solved with actual case study data. The results of sensitivity analysis of this real data set showed that the effect of the percentage of imperfect products and type one inspection error have a significant impact on the total profit function. Eventually, based on these results, managerial insights and some implications for future contributions are outlined
