1 Perishable material sourcing and final product pricing decisions for two-echelon supply chain under price-sensitive demand
تصمیم گیری برای تهیه مواد فاسدشدنی و تصمیمات قیمت نهایی محصول برای زنجیره تأمین دو طبقه تحت تقاضای حساس به قیمت-2021
This paper considers a single product supply chain involving a producer/processor and a retailer. The producer/ processor procures and processes perishable materials such as fruits and milk whose demand are often price- sensitive. We model the dyadic relationship as a Stackelberg game to understand how product perishability and the price-sensitive demand of such products can influence the procurement, production, and sale. The producer/processor is the leader and decides on the processing time of the materials and the wholesale price of the product to maximize profit. The retailer as the follower decides on the sale price of the product and order quantity to maximize profit under a price-sensitive demand setting. Propositions and lemmas for optimality are posed, and the model is validated numerically. Our results suggest that the retailer’s profit cannot be worse than the producer/processor under a price elastic demand. With a high deterioration rate or shrinkage, the producer/ processor should improve the storage conditions or processing capacity within certain constraints for better overall supply chain profitability. Finally, both the producer/processor and the retailer need to consider the price sensitivity of consumers when making pricing decisions.

2 An age-based lateral-transshipment policy for perishable items
یک سیاست انتقال عرضی به کشتی مبتنی بر سن برای کالاهای فاسد شدنی-2018
Lateral transshipment is an efficient policy designed to improve the performance of a supply chain. Despite the importance of transshipment for perishable items, few studies consider the issue of perishability. Currently, transshipment in some blood supply chains is based on the age profile of units in hospitals. However, decisions such as the age threshold are made empirically and are fixed for all hospitals. In this paper, we propose a new transshipment policy for perishable items based on the age of the oldest item in the system to improve supply-chain performance. The proposed model has applications for transshipping blood units between hospitals. We develop a heuristic solution using partial differential equations to compute performance measures and cost function. The results demonstrate that our transshipment policy is effective under various circumstances such as lost sale and backordering. We also compare the performance of the suggested transshipment policy to the transshipment policy that is currently practiced in some Australian hospitals (which is an aged based proactive transshipment policy with an empirically set threshold). The results demonstrate that by setting the optimal threshold, hospitals could transfuse units with the same average age of the current policy, while reducing their total inventory cost by approximately 61%.
