Supply chain coordination has received substantial attention in the operations literature in recent years. Coordination issues in supply chains arise due to several factors, an important one being the difference in the cost impact of inventory and replenishment decisions on the manufacturer and retailer. In this paper, we address this asymmetry in cost impact that can lead to sub-optimal channe...

Interdependence of minor ordering costs occurs in joint replenishment of inventory when the cost of placing an item in an order depends on which other items are also in the order. In this paper, we propose an evolutionary algorithm (EA) for joint replenishment of inventory which allows for the interdependence of minor ordering costs. Since solutions to the joint replenishment problem (JRP) can ...

We consider the problem of determining (for a short lifecycle) retail product initial and replenishment order quantities that minimize the cost of lost sales, back orders, and obsolete inventory. We model this problem as a two-stage stochastic dynamic program, propose a heuristic, establish conditions under which the heuristic finds an optimal solution, and report results of the application of ...

This paper develops a mathematical model using differential equations and considers a bullwhip effect in a supply chain network with multiple retailers and distributors. To ensure the stability of the entire system and reduce the bullwhip effect, a robust control method and an inventory replenishment policy are proposed. This shows that the choice of the output matrix may reduce the bullwhip ef...

This work is motivated by the need to solve the inventory routing problem when implementing a business practice called vendor managed inventory replenishment (VMI). With VMI, vendors monitor their customers’ inventories, and decide when and how much inventory should be replenished at each customer. The inventory routing problem attempts to coordinate inventory replenishment and transportation i...

This paper deals with an optimal replenishment policy for deteriorating items with multi-variate demand and partial backlogging. The proposed model allows for (1) multivariate demand replenishment cycles, (2) partial backlogging, and (3) time-varying shortage intervals. Consequently, the proposed model is in a general framework for that inventory models includes these above assumptions. We show...

The purpose of this study is to investigate the impact of trade credit in the inventory system. It explores an inventory system with noninstantaneous replenishment under conditions of permissible delay in payments. In practice, the supplier allows a certain fixed credit period to settle the account for stimulating retailer’s demand. Besides, the supplier can offer cash discount to encourage ret...

T work is motivated by the need to solve the inventory routing problem when implementing a business practice called vendor managed inventory replenishment. With vendor managed inventory replenishment, vendors monitor their customers’ inventories, and decide when and how much inventory should be replenished at each customer.

T article studies a single-location inventory model with random leadtimes. Inventory is replenished by a single supplier who, at the time a replenishment order is received, knows exactly when the order will be delivered. In other words, the supplier knows the leadtime for every replenishment order. Suppose the singlelocation inventory system is managed by a retailer. The objective of this artic...
