G-TOS is the TOS control version for group-level port clusters. With its ability to interconnect multiple terminals, it meets the requirements for collaborative operations among member ports within the group as well as between upper and lower levels. The group-level container TOS system supports centralized business planning and data, which is more conducive to business management and control of group-level (provincial) ports. Centralization is not just about data sharing and interaction, but also about centralization of decision-making and management in the production and operation process, while localizing grassroots business development. Users can carry out production operations at terminals in different locations and time zones under effective management of the group.
