When running agent-based simulations using ready-made components, one usually faces heterogenity problems both for the agents implementation and for the underlying platform. To circumvent these kind of hindrances, we introduce a wrapper technique for mapping the functionality of agents living in...

In this paper, we demonstrate some properties of Alpha-stable (stable) random variables and processes. It turns out that with the use of suitable statistical estimation techniques, computer simulation procedures and numerical discretization methods it is possible to construct approximations of...

The purpose of this paper is to illustrate the usefulness of Keynes' approach by modeling it using system dynamics. As this technique allows the researcher to place the analysis in time it is especially well suited to the task. It also allows us to see exactly which elements seem to create the...

This paper builds a system-dynamics model of the Mexican economy and tests several propositions regarding policy and income inequality. It concludes, among other things, that one of the most significant developments over the past twenty years has been the declining wage paid to those in the...

Navigational systems assist drivers in finding a route between two locations that is time optimal in theory but seldom in practice due to delaying circumstances the system is unaware of, such as traffic jams. Upon arrival at the destination the service of the system ends and the driver is forced...

During metamodel-based optimization three types of implicit errors are typically made.The first error is the simulation-model error, which is defined by the difference between reality and the computer model.The second error is the metamodel error, which is defined by the difference between the...

This paper demonstrates the impact of particular factors – such as a non-normal error distribution, constraints of the residuals, sample size, the multi-collinear values of independent variables and the autocorrelation coefficient – on the distributions of errors and residuals. This explains...

This study suggests that demand management through pricing policies can be used to solve water supply problems. A demand function for water was developed using cross-sectional water data. The demand function was used in a simulation analysis to determine reservoir capacity needed to supply water...

The main objectives of Task Order 4136 are (1) the design of improved freeway on-ramp metering strategies that make use of recent developments in traffic data collection, traffic simulation, and control theory, and (2) the testing of these methods on a 14-mile segment of Interstate 210 Westbound...

Many urban regions in the U.S. are planning to build extensive networks of new high-occupancy 3ehicle (HOV) freeway lanes. Past modelling efforts are reviewed and travel demand simulations by the authors are used to demonstrate that new HOV lanes may increase travel (vehicle-miles) and increase...
