震災などの災害時には瓦礫による閉塞などで道路網は大きな打撃を受け,平常時から状況が大きく変化する.それに加えて平常時には標識やカーナビなどで容易に得られる道路や交通状況の情報が得られなくなることで,災害時はドライバが行動を決定するために必要な情報が非常に乏しい状態だと言える.阪神・淡路大震災で通行可能だと判明した主要道路に車両が殺到し大きな渋滞が発生したように,このような状態では,交通当局がどのような情報を提供するかが状況に大きな影響を与えると考えられる.本研究では,災害時を想定した道路ネットワーク上で交通管理策と一般車両が得られる情報の種類でどのように交通状況が変化するか,交通シミュレーションによって検証する.
In the Special Project for Earthquake Disaster Mitigation in Urban Area, which is called 'DAI-DAI-TOKU', integrated disaster simulation systems are developed. One useful application of these simulation systems is risk-communication, in which local governments and citizens share information of risks. In this paper, the requirements and subjects are discussed to carry out risk-communication (RC) with disaster simulation systems. We also report a case of RC to show the usefulness of simulations.
The society is increasing the complexity. It is a complexity according to treated object and regulations system, etc. In such a situation,the construction of a variety of management systems are needed. Quality management, environmental management, risk management, and internal control management, etc. Because the object that the management system treats is complex, the information system to support it is needed. It is necessary to arrange a complex concept to the construction of the information system, and to share the concept among parties concerned. Moreover, the arrangement, sharing, and recycling information and knowledge according to the operation of the information system should be possible. In this paper, it proposes the method of constructing the construction of the information system that supports the management system by using the ontology technology.
In the small and medium manufacturing industry, it is difficult to employ the professional IT engineer, so many manufacturing engineer have to cover the IT area business. These manufacturing industry require the course of education of IT engineer. We have held that course for a few years. In this course, each member are able to learn basic skill about IT, but they want to learn more sophisticated technology. Currently, we are under examination about new method.
