ASSESSMENT OF SOCIAL COSTS ASSOCIATED WITH THE STAFF REDUCTION FOR INFRASTRUCTURE MAINTENANCE

Abstract

 In order to maintain the lives of people in the region, adequate maintenance of the infrastructure such as patrol and inspection is needed. However, while the staffs and their time for the maintenance are reducing, the interest is not sufficiently directed to the social risks and costs incurred by the reduction. In this study, we develop the method for evaluating the social costs under the personnel constraint by dynamic programming. In addition, sensitivity analysis is conducted to show how the risk will change if the size of the residential areas is analyzed.
