  • Patent number: 10496059
    Abstract: An operational control management method of determining a possibility of parallel execution of multiple operational controls that are included in a workflow, in which a computer performs processing includes judging whether a first operational control that is to be executed next and a second operational control that follows the first operational control are detailed determination targets, based on operation categorization information that results from categorizing each of the multiple operational controls based on an operation target and operation content; and determining a possibility of parallel execution based on relationships of the first operational control and the second operational control to the operation target and on operation situations of operation targets, with which the first and second operational controls are associated, in a case where the first operational control and the second operational control are the detailed determination targets.

  • Patent number: 9940598
    Abstract: A first executing unit executes, among tasks included in a first workflow, a first task group including one or more tasks using a resource. When a task included in the first task group is stopped, a rollback processing unit restores the resource to its former state prior to the execution of the first task group. After the resource is restored to the former state prior to the execution of the first task group, a second executing unit starts executing, among tasks included in a second workflow, a second task group including one or more tasks using the resource.

  • Patent number: 7965602
    Abstract: In the information recording apparatus, by driving the light source by the pulse signal corresponding to the recording signal, the laser pulse corresponding to the recording signal is irradiated onto the recording medium. The recording signal has the mark period to form the recording mark, and the space period in which the recording mark is not formed. In the mark period, the output level of the laser pulse changes between the normal level and the writing level, thereby, the recording mark is formed on the recording medium. On the one hand, over a predetermined period in the space period, the output level of the laser pulse is changed to the low level lower than the normal level. Thereby, the heat accumulation onto the recording medium, due to the transient response of the laser pulse in the mark period, is reduced, and in the mark period after that, the correct recording mark can be formed.
