Software life extension time determination system, software life extension time determination method, and program

摘要

A software life extension time determination system includes an aging-state-model storing unit configured to store a first state model representing a state change of software due to aging of software, a software-life-extension-state-model storing unit configured to store a second state model representing a state change of the software due to software life extension processing, a parameter input unit configured to receive an input of parameter values of the first state model and the second state model, an evaluation-function storing unit configured to store an evaluation function for deciding values of performance and availability targeted by the system, a state-model analyzing unit configured to analyze the first state model and the second state model by using the parameter values and the evaluation function, and a software-life-extension-time determining unit configured to determine, on the basis of analysis results of the first state model and the second state model, whether the software life extension processing is implemented.
