Abstract
Many infrastructures were built in 1950’s and 60’s intensively in Japan. They got older in half a century, and now it is an urgent task to inspect, monitor and maintain such aging infrastructures. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) renewed the guideline of tunnel inspection and monitoring in 2014. In this research, we proposed optimization models to level the yearly budget for tunnel inspections and monitoring activities under the MLIT’s guideline. It is very important to resolve the bias of the cost of inspection and monitoring from year to year because Japanese local governments adopt the single-year budget system and would like to set aside the constant budget for inspection and monitoring each year. We conducted some numerical experiments with the practical data of tunnels and confirmed the effectiveness of our proposed models.
