In many cases, data generated by executing a simulation model are summarized and printed as part of each model run. As the objectives of simulation projects have become more ambitious and complex, creating summaries in only this way has been found to be unsatisfactory. Recently, software has...

A factorisation method is described for the fast numerical solution of constant tridiagonal Toeplitz linear systems which occur repeatedly in the solution of the implicit finite difference equations derived from linear first order hyperbolic equations, i.e. the Transport equation, under a...

An integrated modelling methodology for metabolic and endocrine systems is presented. Particular emphasis is given to model identification and validation and their inter-relationship. Both theoretical and practical identifiability analyses are reviewed. Model validation, involving...

Traffic behavior along an urban roadway is explored using a continuous simulation model of a leader-follower pair of vehicles. The model employs a non-linear car-following differential equation that characterizes the motion of the pair. The implementation of the conceptual model is programmed in...

This paper simulates the sampling distributions of the rate parameter and the mean residence time (MRT) estimators for a specific two-compartment model. Two forms of measurement error, one additive and the other multiplicative, and two forms of weighting structures, one unweighted and the other...

Increasing water demand, conflicts among utilizations, water-body pollution have given a considerable impulse to the application of systems analysis techniques also to the field of groundwater resources management. In line with this, some mathematical simulation and optimization models taking...

The study of aquatic ecosystems has taken advantage of the development of mathematical models considered as tools applied for comprehension, simulation and prediction. But their final adjustment is connected with modelling of turbulent fluxes which interprets the mixing of various components and...

The Auto-Regression method was applied to the modelling of leukemic states. The number of two kinds of normal cells and of a kind of abnormal cells in the peripheral blood were taken as output variable. The model obtained explained the trend of the normal cells in the prediction, while it could...

Nonlinearity, inherent in physical systems, can be simulated using elementary catastrophe theory. In this paper, we present a general framework for the application of this theory to environmental systems and demonstrate its practicality in a series of quantitative models consisting of the...
