Title:
SYSTEM DESIGN IMPROVEMENT ASSISTANCE DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/121934
Kind Code:
A1
Abstract:
A system design improvement assistance system acquires a mathematical model with which the quality of an information processing system which is the subject of an evaluation is evaluated, and correspondence relation information which denotes a correspondence relation between each component of the information processing system and a parameter set in the mathematical model which is associated with each of the components. On the basis of the mathematical model and the correspondence relation information, the system design improvement assistance system analyzes the sensitivity which denotes a change in the quality of the information processing system with respect to changes in each of the components, and outputs a sensitivity analysis result on a per component basis.
