ABSTRACT
ABSTRACT We propose a framework and model to estimate the reliability of power supply systems for public sector facilities in view of seismic disaster risks. The model optimizes the installation of backup power supply systems in view of the locations of public facilities in predetermined areas. In multivariate optimization, the reliability of backup systems to be allocated in an area was defined as the product of the probability of a system not failing during a service period, for which seismic disaster risk was estimated, and the mechanical efficiency of backup systems necessary to maintain the function of the facilities during the period. In the optimization scheme, reliability is to be maximized, at the expense of economic efficiency and mechanical efficiency when installing the backup systems.
