System and method for managing mobile workers

Abstract

A system manages mobile workers and includes a plurality of clients and a server. A database includes a plurality of target objects that are classified corresponding to facilities assets to be worked on by a mobile worker and attributes of each target object, including any tasks to be performed on target objects. A rule engine determines algorithms based on a utility function for partitioned jobs wherein different algorithms are selected and used for different partitions to schedule jobs and mobile workers in selected different regions. An algorithm is selected based on a weighted sum that is calculated from a possible number of work schedules, jobs and mobile workers for each partition. A selected policy for a job environment determines how mobile workers, jobs and work schedules are partitioned. A plurality of system agents automate supervision.
