FEEDFORWARD CONTROL METHOD, SERVICE PROVISION QUALITY CONTROL DEVICE, SYSTEM, PROGRAM, AND RECORDING MEDIUM THEREFOR

摘要

A feedfoward control method for solving the problems, i.e., "lack of function of evaluating an appropriate control idea", "lack of function of evaluating/executing control orientation", and "lack of function of correcting/checking a control idea", a service provision quality control device, a system, a program, and a recording medium are provided. A service provision quality control device includes a simulation unit (504) for estimating state estimation vector values on the basis of the vector values of the present state and the history state of a measurement statistic while compensating the state estimation vector values with a future time and a judging unit (506) for comparing the estimated state estimation vector values one by one with the target state vector value concerning the control target which is agreement service level information, calculating the control standard deviation, and judging whether or not control operation is required. While the implementation environment of the description of a workflow is being virtually varied in the service provision quality control device, the judgment of whether or not simulation and control operation are required is repeated. An adjusting unit (507) adjusts the evaluation condition of the implementation environment until the control standard deviation decreases to a predetermined value or less under the condition that the repetition is performed at most predetermined times.
