New city logistics approaches are needed to ensure efficient urban mobility for both people and goods. Usually, these are handled independently in dedicated networks. This paper considers conceptual and mathematical models in which people and parcels are handled in an integrated way by the same taxi network. From a city perspective, this system has a(More)

Real world models of large-scale crowd movement lead to computa-tionally intractable problems implied by various classes of non-linear stochastic differential equations. Recently, cellular automata (CA) have been successfully applied to model the dynamics of vehicular traffic, ants and pedestrians' crowd movement and evacuation without taking into account(More)
In this study we show by means of computational experiments that a pseudo-Boolean approach leads to a very compact presentation of p-Median problem instances which might be solved to optimality by a general purpose solver like CPLEX, Xpress, etc. Together with p-Median benchmark instances from OR and some other libraries we are able to solve to optimality(More)
