Service overview

Digital Twin based Consulting Service

Digital Twins have attracted attention as a concept for Digital transformation in recent years. Digital Twin refers to a concept that uses digital technologies to collect Physical-World data and build a model in a Digital-Environment, and to the model in the Digital-Environment itself. Conduct Simulations and analysis in the digital environment, and discovering potential improvement opportunities or risks which are overlooked or not known in the Physical-World, helping to predict future changes and the effects of accidents, etc. This is an entirely new technical approach compared to a traditional IT approach for improving manual processes.
The use of Digital Twins has begun in various domains such as manufacturing, energy, and social infrastructure. In this page, you can find Railway DX Consulting Services in which Toshiba Digital & Consulting Corporation applied the Digital Twin concept into train planning operation ahead of the world.

※This service is currently being rolled out for UK railway operators. Proposals for other countries are currently in the works.
