Information system configuration supporting apparatus, the information system configuration supporting method, and an information system configuration supporting program

摘要

Disclosed are an information system construction assistance device and the like that simply implement construction assistance that meets user demands. The information system construction assistance device includes a system model selection unit which, when construction requirements are input, selects a system model that meets construction requirements from a system model information DB, an operation information acquisition unit which acquires operation information from an operation information DB on the basis of a selected system model group, a parameter calculation unit which uses parameters included in the operation information to calculate evaluation parameters, a performance evaluation unit which uses the evaluation parameters to evaluate the performance of the selected system model, a sizing factor determination unit which compares the result of the evaluation with the input construction requirements to determine whether or not a sizing factor for the selected system model is specified while maintaining construction requirements set mandatory, and a relaxed conditions presentation unit which, when the sizing factor is not specified, presents relaxed construction requirements.
