A control method includes: storing, at a control server, respective identifiers for a plurality of sub-regions in a facility; for each sub-region identifier, a location of the sub-region in the facility and an operational constraint associated with a mobile automation apparatus; at the control server: obtaining a job definition indicating a set of the sub-region identifiers and a task; retrieving the locations and the operational constraints corresponding to the set of sub-region identifiers from the repository; allocating the set of sub-region identifiers to a plurality of subsets of sub-region identifiers, each subset having a shared common operational constraint; for each subset of sub-region identifiers, generating a task fragment containing the subset of sub-region identifiers, and the common operational constraint; and sending the task fragments and an identifier of the task to the mobile automation apparatus for performance of the task at each of the set of sub-region identifiers.
