PROBLEM TO BE SOLVED: To calculate probability that a processing delay due to garbage collection deviates from a quality reference.SOLUTION: A processing delay probability calculation device 1 includes: GC probability calculation means 14 for accepting the input of a model that a plurality of servers successively process an input signal, and for calculating garbage collection occurrence probability and a delay time due to garbage collection on the basis of the processing time of the input signal, a garbage collection occurrence frequency and a garbage collection stop time in each server; event decomposition means 15 for decomposing events into the events encountering the garbage collection and the events non-encountering the garbage collection in each server, and for calculating the occurrence probability and the delay; and delay probability calculation means 16 for calculating the total sum of the occurrence probability of the events whose delay exceeds a target value among the events decomposed by the event decomposition means 15, and for calculating probability that the total sum of the delay due to garbage collection exceeds the target value. |
