Abstract: System and method for achieving reproducibility of a simulation operation while reasonably keeping an operation speed. A peripheral scheduler clears completion flags of all the peripheral emulators to thereby start parallel operations thereof. Then, based on processing break timing set for the individual peripheral emulators, the peripheral scheduler finds one of the peripheral emulators which is scheduled to reach a processing break at the earliest. The found peripheral emulator is referred to as a peripheral P. In a case where a time of the processing break of the peripheral P is T, the peripheral scheduler continues execution of processor emulators and plant simulators up until a time point of the time T. The peripheral scheduler waits for setting of a completion flag of the peripheral P. In response to the setting, the peripheral scheduler performs data synchronization among the peripheral P, the processor emulators, and the plant simulators.

Abstract: Flow control for a workflow controlling system is achieved wherein a business document flows among a plurality of participants by, at a system which includes a server apparatus including a storage device and terminal apparatus connecting to the server apparatus via a network, generating a document which includes data and rules responding to a request from one of the terminal apparatus and storing it in the storage device, receiving an update request on the document from the first terminal apparatus, determining whether the update request is appropriate or not, and if the update request is appropriate then executing the update on the document, and determining whether the workflow/process was completed or not, and if not completed then identifying the second terminal apparatus which can update next and notifying it.
