This article presents a method to identify "Absolute and Relative Employment Concentration (AREC) areas" for a particular industry. Two novel characteristics of the method are that it simultaneously analyses AREC, and that it combines spatial concentration per area with the spatial concentration...

Although spatial concentration of logistics firms in logistics concentration areas can be beneficial for society at large, there is not much research on the relationship between land allocation policies and logistics concentration areas. This paper analyzes land allocation policies by means of a...

This paper analyzes the relationship between freight accessibility and logistics employment in the US. It develops an accessibility measure relevant for logistics companies based on a gravity model. This allows for an analysis of the accessibility of US counties focusing on four different modes...

Retail store managers may not follow order advices generated by an automated inventory replenishment system if their incentives differ from the cost-minimization objective of the system or if they perceive the system to be suboptimal. We study the ordering behavior of retail store managers in a...

Seaports can be meaningfully analysed with a cluster perspective. In this perspective, seaports are regarded as concentrations of economic activity related to the arrival and service of ships and cargoes at ports. This perspective has two main advantages: first, it draws attention to forces of...

In this paper we derive approximations for the expected amount of outdating (waste) in an inventory system with perishable products, periodic review, positive lead time, fixed case pack sizes and a First-In-First-Out withdrawal policy. Demand is discrete and stochastic. Demand which is not met...

We present an approach to improve forecast accuracy by simultaneously forecasting a group of products that exhibit similar seasonal demand patterns. Better seasonality estimates can be made by using information on all products in a group, and using these improved estimates when forecasting at...

An approximation for the fill rate, i.e. the percentage of demand being delivered from inventory on hand immediately, is derived for items in a periodic review inventory control system with lost sales. We assume demand is stochastic and discrete, lead-times are positive and replenishments are...

The quality and availability of labour is essential for the economic performance of clusters. The availability of labour in clusters is superior compared to locations outside clusters, because labour is more mobile in clusters, education services in clusters are better and employees in clusters...

The cluster-concept is often-used to analyse a country's key industries. The maritime industry is one of the most well-defined clusters in the Netherlands. Although the competitiveness of a cluster depends on the interaction in a cluster, research on cluster dynamics is limited. This paper...
