PROBLEM TO BE SOLVED: To provide an event processing system 23 capable of reliably executing a process that corresponds to event messages, and of increasing the efficiency of processing the event messages. SOLUTION: In the event processing system 23, the event messages received according to the transition of the state of an IT service system 40 are held in an event message holding part 233 in order of issuance. From the event messages in the event message holding part 233, an event message is retrieved such that the state of the IT service system 40 after the event message has been issued matches the state of the IT service system 40 before the oldest event message in the event message holding part 233 was issued. When the event message can be retrieved, the event messages from the oldest one to the one retrieved are deleted from the event message holding part 233. COPYRIGHT: (C)2007,JPO&INPIT
