Development of solution tools to support the decision-making on safety plans

通过三年的安全计划制定活动，我们在以下各个领域做出了贡献。(1) 2011年东北地震中铁路事故与维修、搜救行动的数据收集与数据分析。(2)提出了急诊医学中设施安全问题、搜索问题、设施配置问题的建模与求解方法。(3)日本与国外的交通网、铁路网、电力网、贸易网等基础网络研究及网络损耗分析。通过以上活动，我们针对这些问题开发了一些计算机辅助规划系统。我们还为日本运筹学学会主办了一次会议和研究会议，就上述主题交流专业人士的意见。

Through our activities on safety-plan making for three years, we contributed to the following individual field. (1) Data-gathering and data-analysis on the followings: railway accident and maintenance, the search and rescue operation in the 2011 Tohoku earthquake. (2) Proposition of modeling and solution methodology for the followings: security problem in facilities, search problem, facility allocation problem in emergency medicine. (3) Research on infra-networks such as transportation net, railway net, electric power net and trade net between Japan and foreign countries and analysis on attrition on networks. Through our activities above, we developed some computer-aided planning systems for the problems. We also sponsored a conference for the Operations Research Society of Japan and research meetings to exchange opinion of professionals about the topics above.
