This paper investigates inventory management issues in a distribution network. The study is motivated by examining the operation of a wholesaling car parts company. Customer service requirements are of paramount importance in this market sector. The

It is regularly asserted that the frequency of orders received by a stockist can be represented as a Poisson process, but very little corroborative evidence has been published. This paper presents some results supporting the assumption. An adaptation

The majority of the range of items held by many stockists exhibit intermittent demand. Accurate forecasting of the issue rate for such items is important and several methods have been developed, but all produce biased forecasts to a greater or lesser

This paper examines half a million observations of the size of orders from customers at an electrical wholesaler. It notes: the distribution of the size of customer orders for a single item (stock keeping unit or SKU) is very skewed and resembles a g

A combination of moving averages has been shown previously to be more accurate than simple moving averages, under certain conditions, and to be more robust to non-optimal parameter specification. However, the use of the method depends on specificatio

In a service environment, a stockist usually has many slow moving items whose infrequency of demand can give rise to forecasting problems. Moreover, when a demand occurs, the request is sometimes for more than a single unit, which results in so-calle

The service level provided by an inventory system can be measured in various ways. If different measures are used at a number of stock-holding depots, difficulties may arise in comparing performance or assessing the impact of depot centralization or

The existence of uncertainty is a feature of the business world. Forecasting does not remove this uncertainty, but sets out to measure and minimize it. This paper suggests decomposing the forecast error into three components, namely the residual unex
