Dynamic Support System Research for Earthquake Prevention Planning based on Petri Net Simulation Methodology on Background Image

(1)地震时消防系统的动态检查和重建：即使在大地震固有的危险带来的混乱中，消防系统也必须可靠。危险分为两种类型，限制性或切断性。如果前者发生，一些活动将被推迟一段时间，如果后者发生，一些活动将无法进行，直到恢复工作完成。利用这些危险性概念及其子网，开发了地震下消防系统的宏Petri网仿真器。在城市地区，大量的民用汽车严重限制了应急交通。这个问题在上述宏网络中被认为是限制性危险之一。为了设置子网的参数，我们还构造了交通阻塞情况下消防车运行的微型Perti网模拟器。我们提出了一个战略指导系统的基础上收集的危险和预测在城市地区的火灾蔓延。(2)迪纳米 ...更多信息 地震时疏散计划情景的校核与重建：疏散计划是一个必须从多个角度进行校核的情景。我们试图支持审查和部署到更安全的一个使用Petri网方法的背景图像规划区的第一个方案。首先，我们开发了城市密集建筑区木结构房屋疏散的Petri网模拟器。房屋倒塌灾害对人员疏散具有一定的限制作用，其作用点也是固定的。但火灾对人员疏散的危害是隔断的，其作用点随着火灾蔓延而扩大。结合火灾蔓延模拟器构建子网络描述该场景，提出备选场地场景设置和地震火灾风险疏散演练规划。其次，开发了中山地区人员疏散的Petri网仿真器。在这里，区域不像城市区域那样平坦。因此，我们引入探测信息技术来收集地理数据，并开发了更多的拟合过程，以建立一个背景图上的避难路径Petri网。少

(1) Dynamical check and rebuilt of fire fighting system at earthquake : Fire fighting system must be reliable even in confusion brought by hazards inherent in a big earthquake. Hazards are classified into two types, restrictive or cutting-off. If the former break out, some of activities are delayed for a certain period and if the latter occur, some of activities become impossible to be performed until recovery works have been finished. We develop macro Petri net simulator of fire fighting system at quake using those hazard concepts and their sub-nets. In urban area, emergency traffic is restricted heavily by a lot of civil cars. This problem is considered in macro net mentioned above as one of restrictive hazards. To set up parameter of sub-net, we also construct micro Perti net simulator for running of fire engines under obstruction of traffic jam. We propose a strategic direction system based on information gathering of hazards and forecast of fires spreading in urban area.(2) Dynami … More cal check and rebuilt of evacuation planning scenario at earthquake : Evacuation plan is a scenario which must be checked from various view points. We try to support to examine and deploy the first scenario into more safety one using Petri net methodology on background image of planned area. Firstly, we develop Petri net simulator for evacuation in urban densely built-up area of wooden houses. Hazard caused from houses collapsed is restrictive to evacuation action and its effective point is also fixed. But hazard caused from fire is cutting-off to evacuation and its effective point is expanded according to fire spreading. We construct sub-net to describe this scenario linking with fire spreading simulator, and propose scenario setting of alternative site and planning of evacuation drill for earthquake fire risk. Secondly, we develop Petri net simulator of evacuation in the intermediate and mountainous area. Here, area is not flat like urban area. So we introduce the probe information technology to gather geographical data and develop more scenario-fitting procedure to build-up refuge rout Petri-net on a background picture. Less
