The paper is concerned with the problem of distributing a current of vehicular traffic on a conducting net between a source domain A and a destination domain B. It is investigated how local decision-making influences globally averaged quantities. The effects of a local, Boltzmann-like...

Path-choice problems in vehicular traffic in urban environments are dominated by an interplay of local decision-making and global optimization. With local routing uncertainties being taken account of by the introduction of an (repulsive) interaction of paths, a variational principle for the...

A scientific methodology in general should provide two things: first, a means of explanation and, second, a mechanism for improving that explanation. Agent-based modelling ( ABM) is a method that facilitates exploring the collective effects of individual action selection. The explanatory force...

Continuous enterprise restructuring is needed for the transition and emerging market economies to become and remain competitive. However, the beneficial effects of restructuring in the medium run are accompanied by large worker displacement. The costs of displacement can be large and...
