The assessment of uninterrupted traffic flow is traditionally based on empirical methods. We develop some analytic queueing models based on traffic counts and we model the behavior of traffic flows as a function of some of the most relevant determinants. These analytic models allow for...

In this paper we study the welfare effects of a budgetary neutral increase in taxes on car commuters in a model that takes into account the presence of employer-paid parking at the workplace. Results include the following. First, we find that the presence of employer-paid parking substantially...

This paper develops a numerical optimisation model to study optimal labour and peak-period congestion taxes under different assumptions on the structure of the labour market. We consider both a competitive labour market and various wage bargaining models, in which wages are determined via...

In Europe, the preferential tax treatment of company cars implies that many employees receive a company car as part of their compensation package. In this paper, we consider a model in which wages and the decision whether or not to provide a company car are the result of direct negotiation...

The impact of transfer batching (also referred to as lot splitting) on the performance of flowshops has received widespread attention in the literature. Most papers have emphasized the usefulness of lot splitting in cutting down average flow times, as it enables the overlapping of operations at...

We propose a supporting framework for the material control system Paired-cell Overlapping Loops of Cards with Authorization (POLCA), which combines the advantages of push systems and pull systems. In our load based version of the POLCA control system, we rely on a multiproduct, multi-machine...

Blocking systems with zero buffers are typical for (semi-)process industries. They have not only th characteristics of limited buffer systems, but if buffer sizes are zero, the equipment is often used as temporary storage. This cause the effective utilization to be higher than the natural...

It is generally known that the mechanism of overlapping operations allows to reduce the average job lead times in a production system. However, a machine may remain idle between two consecutive sublots belonging to the same job, due to a difference between its own setup and processing times and...
