Abstract

A failure prediction apparatus includes a memory and a processor coupled to the memory. The processor acquires a score based on an output of each of a plurality of sensors associated with each of a plurality of circuit arrangement regions, in each of the plurality of circuit arrangement regions a logic circuit constructed by programming is arrangeable, and performs a process of making a determination on a possibility of an occurrence of a failure with respect to each of the plurality of circuit arrangement regions based on the score for each of the circuit arrangement regions.
