✦ Synopsis

This paper presents an automated system for parameter identification of inelastic constitutive models. The system can find good approximate parameters for various identification problems under a user-friendly environment. In order to identify parameters efficiently and in a robust manner, an optimisation method is first proposed. The paper then describes the generalisations applied of modelling, simulation and identification for its various identification uses. Finally, a system, which is developed in conjunction with the generalisations, is described. The performances of the proposed optimisation method and the developed system were investigated with actual material data, and their effectiveness was consequently confirmed.

## Abstract The parameters of a constitutive model are usually identified by minimization of the distance between model response and experimental data. However, measurement failures and differences in the specimens lead to deviations in the determined parameters. In this article we present our resu

AbstractÐThis paper considers a lane routing problem in an Automated Highway System (AHS). Lane routing is important because the problem of managing the trac ¯ow on a multilane AHS plays a major role in an urban environment. On the other hand, because analytical approaches are impossible for various
