Abstract
Armed with a number of modern and emerging visibility technologies and facing increased competition from the internet channel, retail managers are seeking ever deeper visibility into store operations. We review two established streams of operations management research that try to overcome shortcomings of common retail data sources. The first is demand estimation and inventory optimization in the presence of data censoring, where imperfect data may cause significant estimation biases and inventory cost inefficiencies. The second is inventory record inaccuracy, where intelligent replenishment and inspection policies may be able to reduce inventory management costs even without real-time tracking technologies like radio frequency identification (RFID). Common themes of these literatures are that lack of visibility can be costly if not properly accounted for, that intelligent analytical approaches can potentially substitute for visibility provided by technology, and that understanding the best possible policy without visibility is needed to properly evaluate visibility technologies. We include a survey of modern and emerging visibility technologies and a discussion of several new avenues for analytical research.

The result is difficult to prove generally. Song (1994) includes a detailed analysis of the conditions required to rank newsvendor stocking quantities for different probability distributions, and these conditions are difficult to verify here.

Here we depart slightly from DeHoratius and Ton (2015) in terminology. DeHoratius and Ton (2015) define “inventory record inaccuracy” as the difference between a store’s recorded inventory position and the physical inventory in the store. Misplaced inventory, which is physically present in the store, does not contribute to inventory record inaccuracy in this definition. In our discussion, we will liberally use the term “inventory record inaccuracy” to refer to the difference between customer-available inventory and recorded inventory. That is, we consider misplaced inventory to be part of inventory record inaccuracy.
