System design method, system design apparatus, and storage medium storing system design program, for analyzing failure restoration procedure
First Claim
1. A system design apparatus, comprising:
- a processor and a memory storing therein a program, wherein the processor is configured to execute the program and thereby implement;
an analysis model receiving unit that is configured to receive an analysis model that represents a failure restoration procedure for a system;
a minimum combination specifying unit that is configured to specify a minimum combination of component failures that does not satisfy a restoration time or a necessary cost requirement, from the analysis model; and
a minimum combination output unit that is configured to output the minimum combination of component failures,wherein the minimum combination specifying unit comprises;
a restoration time estimation unit that is configured to estimate the restoration time of the system; and
a cost estimation unit that is configured to estimate the necessary cost requirement for restoration of the system;
andwherein the analysis model is a state transition model in which a state transition occurs based on a specific probability distribution.

Abstract
Provided are a system design method, a system design system, and a system design reform assistance program. A system design apparatus includes a unit for receiving an analysis model which represents a system failure restoration sequence, a unit for identifying, from the received analysis model, a minimum combination of component failure which does not satisfy either a restoration time requisite or a necessary cost requisite and a unit for outputting the identified minimum combination of component failure. The unit for identifying the minimum combination of component failure further includes a unit for estimating the restoration time of a system, and a unit for estimating the cost required for restoration of the system.
