土木分野から考える施設の維持管理戦略

抄録

Strategies for infrastructure management must be based on the concept of “tacit expectation for eternity.” This would be a principle for the administrator of infrastructures even though the variety of facilities and their characteristics are diverse. When the target of infrastructure management is discussed, it is important to know various aspects of the facilities as well as the capabilities of the administrator in advance. This will be help in identifying an appropriate solution. There are three different situations for the people engaged in infrastructure management: asset management, macromanagement, and micromanagement-and these are defined and compared to clarify the differences. Moreover, there are some conflicts between accountants and maintenance engineers concerning asset value and a description of the deterioration curves of facilities. Both sides should know each other's situation and identify a more feasible solution. The difference of capabilities between design and maintenance engineers is discussed by citing neuroscience, highlights the shortage of expert maintenance engineers.
