Applied Mathematical Modelling

An inventory model with non-instantaneous receipt and exponentially deteriorating items for an integrated three layer supply chain system under two levels of trade credit

In the past, research in operations management focused on single-firm analysis. Its goal was to provide managers in practice with suitable tools to improve the performance of their firm by calculating optimal inventory quantities, among others. Nowadays, business decisions are dominated by the globalization of markets and increased competition among firms. Further, more and more products reach the customer through supply chains that are composed of independent firms. Following these trends, research in operations management has shifted its focus from single-firm analysis to multi-firm analysis, in particular to improving the efficiency and performance of supply chains under decentralized control. The main characteristics of such chains are that the firms in the chain are independent actors who try to optimize their individual objectives, and that the decisions taken by a firm do also affect the performance of the other parties in the supply chain. These interactions among firms’ decisions ask for alignment and coordination of actions. Therefore, game theory, the study of situations of cooperation or conflict among heterogenous actors, is very well suited to deal with these interactions. This has been recognized by researchers in the field, since there are an ever increasing number of papers that applies tools, methods and models from game theory to supply chain problems.

Supply chain collaboration

A bi-level credit period coordination scheme is proposed for a supplier-retailer supply chain with a periodic review replenishment policy and price-credit dependent demand. The credit period offered by the retailer to its customers is a promotional effort to induce customer demand and gain market share. We model the problem under decentralized, centralized, and coordinated structures. Through the incentive scheme, the supplier seeks to increase the retailer’s credit period by offering the retailer a credit period. Our results suggest that coordinating the inventory, pricing, and credit financing can improve the overall chain and individual member profitability.
