This article analyzes a continuous time back-ordered inventory system with stochastic demand and stochastic delivery lags for placed orders. This problem in general has an infinite dimensional state space and is hence intractable. We first obtain the set of minimal conditions for reducing such a...

This paper presents and applies a stage-of-fabrication inventory model to the UK manufacturing sector. The model emphasises the interaction between input (raw materials and work-in-process) and output (finished goods) inventories. This interaction is an important empirical regularity and proves...

Motivated by the contrasting strategic choices made by two divisions of 7-Eleven regarding the risk ownership of excess inventory, our research aims to understand the drivers of the choice between consignment and retail ownership of inventory and to develop rules of thumb for determining what...

There is a broad consensus that mankind must reduce carbon emissions to mitigate global warming. It is generally accepted that carbon emission trading is one of the most effective market-based mechanisms to curb the amount of carbon emissions. This paper investigates how firms manage carbon...

Motivated by the need of small and medium-sized hospitals to improve their platelet inventory management, we develop a finite-horizon dynamic programming model to optimize inventory control for perishable product (e.g., platelet) with 3-period shelf-life. In addition to identifying the best...

In this article, we study the impact of implementing corporate social responsible (CSR) practices on firms' inventory policy. We propose that there is an inverted U-shaped relationship between firms' CSR and their inventory levels. Two elements explain such a proposal. First, stakeholders have...

A model is built in order to study the impact of variance of demand on the supply chain inventory and also to identify the best combination of the inventory policy across the supply chain. Inventory management at independent entities is to either prevent stock out or for having lowest funds...

We study the aggregate implications of (S,s) inventory policies in a dynamic general equilibrium model with aggregate uncertainty. Firms in the model's retail sector face idiosyncratic demand risk, and (S,s) inventory policies are optimal because of fixed order costs. The distribution of...
