Application: Calculation system and calculation method (Patent ID: US20240103505A1)

The patent filed by Hitachi Ltd. describes a calculation system and method for executing simulations on assets within a digital twin environment. The system includes a requirement condition calculation unit that determines the output specifications needed for downstream hierarchies and a requirement adjustment unit that modifies the output specifications based on requirements from downstream hierarchies. Additionally, the system calculates the output specifications required for upstream hierarchies based on the adjusted specifications. The method involves calculating output specifications considering domain knowledge of assets, execution period, and simulation results to ensure sufficient calculation resources are available. It also includes calculating charges for using the digital twin service based on the variance between current and required output specifications and displaying images representing calculation resources, costs, and simulation results for each asset.

Overall, the patent focuses on optimizing simulation processes within a digital twin environment by efficiently managing output specifications for hierarchically connected assets. The system and method aim to ensure accuracy, sampling rates, and calculation resources are adequate for simulations, taking into account domain knowledge and actual calculation results. Additionally, the patent introduces a mechanism for calculating charges based on output specification differences and provides visual representations of calculation resources, costs, and simulation outcomes. This innovation by Hitachi Ltd. can potentially enhance the effectiveness and cost-efficiency of simulations within digital twin environments, benefiting industries that rely on accurate asset simulations for decision-making and optimization purposes.
