A service provision quality control device according to the present invention includes a simulation processing unit which predicts a group of state predicting vector values on the basis of vector values of a current state and a past state of measurement statistic, a judging unit which judges whether a control operation is necessary or not on the basis of the state predicting vector value and a target state vector value whose control target is agreed service level, and an adjusting unit which adjusts evaluation condition of an execution environment repeatedly until control deviation becomes not larger than a predetermined value under the condition that iteration number is not larger than a predetermined value which is corresponding to an upper limit value.

Service provision quality control device

Disclosed are a workflow monitoring control system, method, and program, wherein, when workflows are executed by passing through processing sections, each provided with business application software, in order, the service quality of the workflows can be ensured in as many workflows as possible with limited computer resources. A workflow monitoring and control system connected to a plurality of processing sections each of which executes a unit process assigned respectively, a unit process being one of parts constituting business data processing, by using business application software and computer resources, comprises a workflow defining means, a service quality lower limit setting means, a service quality calculation means, a quality insufficiency judging means, a computer resource reallocation means.

Workflow monitoring and control system, monitoring and control method, and monitoring and control program

A rejection determination is made taking into consideration of an agreed service level for a combine workflow executed on a combine workflow system wherein a plurality of business application are collaborated with one another for business collaborations. A state is expressed which will appear when the combined workflow is hypothetically rejected, based on the progress thereof. A processing operation of the combined workflow is predicted based on the expressed state, taking into consideration the influence exerted on the plurality business application systems and the plurality of workflow systems in respect of response performance. A processing operation, which is the result of the prediction, and historical information of event information from the event information recording means are retrieved, and an evaluation value is calculated based on the result of the statistical processing of the historical information. It is determined whether or not the evaluation value satisfies a condition defined by said agreed service level. When the evaluation value does not satisfy the condition defined by the agreed service level, a rejection-target-specific progress for selecting/specifying an execution which has an arbitrary progress equal to or less than a maximum progress, is generated as a rejection target.
