Inventory inaccuracy is common at retailers. At many retailers, a cash register records incoming orders and outgoing sales, but not the demand or the shrinkage. The shrinkage refers to spoilage or pilferage of inventory. The demand differs from the sales in the periodic-review lost-sales...

Markov-modulated processes have been used in stochastic inventory models with setup costs for modeling demand under the influence of uncertain environmental factors, such as fluctuating economic and market conditions. The analyses of these models have been carried out in the literature only...

We develop a continuous time Newsvendor model to determine the optimal inventory level for commodities in an established financial market. Unlike most models in literature, the newsvendor is not necessarily risk-neutral and chooses the order quantity that maximises the expected utility of the...

Inventory management for a new product is challenging due to the lack of historical data, and sales data cannot fully capture the actual demand as excess demand is usually unobservable. Meanwhile, demand-related features are available in the era of big data. We study how to determine the...

We study a firm's optimal transshipment problem considering the impacts of setup costs for transshipment and demand distribution shapes. We assume that the demand follows a three-point distribution, which changes from a degenerate distribution, to a unimodal distribution, and to a bimodal...

This article analyzes a discrete time lost sales inventory system with partially observed demand and unobserved shrinkages which happen both before and after the demand realization. When the demand exceeds the remaining inventory, the unmet demand is lost and unobserved. This problem in general...

Inventory models need some specification of the distribution of demand in order to find the optimal order-up-to level or reorder point. This distribution is unknown in real life and there are several solutions to overcome this problem. One approach is to assume a distribution, estimate its...

In the movie industry, an intriguing question is why studios cluster their big theatrical hits during the Memorial Day or July 4th weekends in the early summer as opposed to the fall. This paper examines the home video industry to provide more evidence on whether booms in theatrical revenues are...
