INFORMATION SYSTEM CONSTRUCTION DEVICE, INFORMATION SYSTEM CONSTRUCTION METHOD, AND STORAGE MEDIUM

摘要

An information system construction device includes a system model selection unit that selects a system model that satisfies a construction requirement among system models when the construction requirement of a system is input, an operation information acquisition unit that acquires operation information of an existing system based on the selected system model and a similar system model, a parameter computation unit that computes an evaluation parameter by using a parameter included in the operation information, a performance evaluation unit that evaluates the performance of the selected system model on the basis of the evaluation parameter, a sizing factor change unit that changes a sizing factor of the selected system model by comparing the evaluated performance of the system model with the input construction requirement, and a system construction unit that constructs the information system by using the system model after sizing factor change.
