Simulation of Urban System ``As It Could Be'' by Multiagent Model

In this paper, a multi-agent system is employed for modeling an urban system. The supposed urban system is composed of three urban agents, i.e. household, base, and service agents. Agents interact each other economically and pay land rents and moving costs. Agents which cannot adapt to the urban system disappear. Agents which survive in the system create new agents and their decision-making rules are followed to the new ones. Using this model, urban land-use pattern is simulated with three different distance constraints. Land-use patterns and rules are compared.

A study on the estimation method of target design engineering quantity considering client satisfaction

Based on the reflection of Hanshin Awaji big earthquake disaster, the target of this study is the development of performance based design method from the point of view of clients. That development aims to propose the estimation method of the rational target design engineering quantity that gives higher performance of satisfaction against the earthquake by using soft-computing method. In this study, the story deformation is adopted as a design engineering quantity.
