Studies on active control of social system based on Artificial Life technology

本研究的主要结果可以概括如下：1.提出了一种制定预防措施的方法，通过利用各种研究和目前正在运作的系统，最大限度地利用各种信息和真实的在线计算机技术等先进技术，减轻地震破坏。本研究着重于实时地震工程的概念和重要性。积极控制的社会系统考虑到人类的行为也被处理.基于大规模地震监测和地理信息系统（GIS），开发了一个大型城市燃气管网地震信息采集与网络报警系统（SIGNAL）。对用户建筑物和管线进行了破坏评估，震级和震源估计，反应谱评估，并根据评估结果进行了停供或保供的决策分析.开发了一种基于虚拟现实技术的人员疏散行为模拟器，并将其应用于迷宫疏散的研究。结果表明，虚拟现实系统可以模拟人的疏散行为，通过虚拟现实技术进行训练有助于人顺利地从迷宫中疏散出来。考虑到灾害演习中存在的一些问题，如演习的习惯性，参与者的减少和意志力的低下，以及演习的安全性，该虚拟现实模拟器具有很高的潜力，可以成为一个有用的减灾工具.根据桥梁在道路网络中的重要性以及桥梁被摧毁时的直接影响来评估与道路网络相关的重要性或关键性。根据桥梁作为重要交通纽带的重要性，可以确定桥梁加固和震后应急响应的优先顺序。

The main results of this study may be summarized as follows :1. A means of establishing preventive measures was presented for mitigating earthquake damage by making the most of a variety of information and such advanced technoligies as computer technologies on-line in real time, using studies and systems now in operation. This study focused on the concept and importance of real-time earthquake engineering. Active control of social systems taking into account human behavior also was dealt with.2. A seismic information gathering and network alert (SIGNAL) system for a large-scale city gas network was developed based on extensive earthquake monitoring and geophraphic information system (GIS). The damage estimation to custimers' buildings and pipelines, estimation of the magnitude and hypocenter, evaluation of the response spectrum, and decision analysis whether to shut-off or maintain the supply based on the estimated results were conducted.3. A new simulator for human evacuation behavior using virtual reality (VR) was developed and applied to study evacuation from a maze. It was found that evacuation behavior can be simulated by the VR system, and the trainig using VR helps smooth evacuation from the maze. Considering the issues related to disaster drill, such as its mannerism, decrease of participants and their low volition, and safety of the drill, this VR simulator has high potential and can be a useful tool for disaster mitigation.4. Importance or criticality in relation to a road network was evaluated in terms of the importance of the route the bridge located in the road network as well as the direct effects when the bridge is destroyed. Priority for retrofitting bridges and for emergency response after an earthquake occurrence can be decided accoring to the importance factor of the bridge as a vital transportation link.
