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 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...

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...

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 study the modeling of a generic assembly system with infinite buffers. This open system consists of two input processes which deliver one component for assembly. The component interarrival times are identical continuously and uniformly distributed. A kit contains one unit of each component...

It is now widely accepted that both large and small lot sizes can cause long lead times and consequently bad customer service in terms of late deliveries. The impact of the lot size on the lead time consists of a convex relationship, implying an optimal lot size minimising average lead time. In...

This paper focuses on modelling the impact of lot splitting on average process batch flow times, in a two-stage stochastic flowshop. It is shown that the traditional queueing methodology for estimating flow times cannot be directly applied to a system with lot splitting, as the arrival process...
