TOMONI®'s Smart Maintenance is a powerful supporter for customers doing maintenance. It accumulates data necessary for maintenance work and provides them out in a manner easy to understand from the user's perspective. Operating data from field plants/factories are stored in the cloud server, data security risks are managed, and cybersecurity requirements are handled and we support customers' equipment operation and management remotely by means of digital technologies and support tools. The in-house trial run of the generative AI (Artificial Intelligence)-enabled TOMONI application has been started, gradually making its usefulness and any possible problems clear to us, and these problems will be dealt with. By utilizing maintenance/operating data accumulated through TOMONI and combining generative AI with the existing applications, new services will be made available to customers as well.
