Parameter estimation and performance measurement in lost sales inventory systems

Article Abstract:

A study was conducted to examine the impact of parameter estimation and performance measurement in lost sales inventory systems. The study focuses on retail markets where customers depend on sales data for information. Out-of-stock products are then shown to have no indication of potential sales lost. Results show that sales data estimation is subject to errors when sales losses are incurred.

Analysing divergent logistic networks with local (R,S) inventory control

Article Abstract:

An analysis of divergent logistic networks is presented. The analysis focuses on networks which feature local inventory control. Nodal inventories are monitored by a periodic review technique based on order-up-to level. The network performance is then examined by applying an approximate method. It is shown that approximation accuracy sets sufficient conditions for designing global networks.

Improving buyer-seller system cooperation through inventory control

Article Abstract:

Cooperation in a buyer-seller system is considered in the case of a monopolistic market. Two models are developed to evaluate how such systems can be improved in terms of inventory control. Greater profits and maximum order quantity are obtained under a cooperative buyer-seller system. Seller wholesale prices to the buyer are also lower with cooperation than noncooperation.
