Strategic Maintenance Management for Civil Infrastructure Systems using Information Technology

在日本，有大量的民用基础设施系统，包括公路桥梁。由于老化的基础设施系统的增加，这些系统的维护将是严重的问题。公路、铁路网等基础设施系统的管理正成为世界各国社会可持续发展的重要问题之一，无论是在发达国家还是在发展中国家，本研究的主要目的是建立战略维护管理的框架。基础设施系统的管理是一项艰巨的任务，因为维护技术取决于所使用的材料、结构质量和自然环境等，因此需要一名熟练的工程师来进行决策。准确、合理地保存和整理寿命结构的劣化环境、损伤环境等勘察/检查记录和维修/改造记录，并发布必要的信息，是寿命结构维修工作的重中之重。要应对这些问题，就必须用信息技术来支持维修。预计信息技术将成为改进维修工作的有效手段，将熟练工程师的专门知识公式化，并分析和评价维修工作的结构条件。具体而言，通过信息网络构建了数据库系统、维修信息搜索引擎、检测数据录入辅助系统等。这些系统用XLM描述，数据也是标准化的。此外，还对该结构的远程监控系统进行了研究。

In Japan, there is vast quantity of civil infrastructure systems including highway bridges. Because of increase of aged infrastructure systems, maintenance of these systems will be serious problems. The management of infrastructure systems such as road ＆ railway networks etc. is becoming one of the most important issues in the sustainable development of societies all over the world, not only in advanced countries but also in developing countries.The main purpose of this study is to make the framework of strategic maintenance management. The management of infrastructure systems is a difficult task, since the maintenance technology is depending on material used, structural quality and natural environment etc., it is necessary to have the know-how of a skilled engineer for decision making. It is the most important thing in the maintenance of lifetime structures that the investigation/inspection records of the deterioration circumstance and damage circumstance etc. and the record of repair/retrofit administered of those lifetime structures are preserved and organized accurately and properly and the necessary information are released. To cope with such problems, it is necessary to support the maintenance by the information technology. Information technology is expected to be an effective means of improving maintenance work, by formularizing the know-how of skilled engineers as well as analyzing and evaluating structural conditions for maintenance work. Concretely, the data base system, the maintenance information search engine, and the inspection data input assistance system, etc. through the information network are constructed. These systems are described with XLM, and data is standardized. Furthermore, the remote monitor system of the structure is examined.
