System and Method for Automatic Fleet Partitioning

A system for automatic fleet partitioning includes client devices and a device management server having tag definition and tag assignment repositories. The server receives and stores, in the tag definition repository, definitions with tag assignment criteria; and for each client device: obtains a client identifier and attribute set; for each tag assignment criterion satisfied by the attribute set, associates a corresponding tag name with the client identifier in the tag assignment repository; and for each tag assignment criterion not satisfied by the attribute set, disassociates the corresponding tag name with the client device identifier. The server receives a command to transmit control data to a subset of the client devices associated with a selected tag name; retrieves, from the tag assignment repository, the client identifiers associated with the selected tag name; and transmits the control data to the subset of the client devices.
