Prioritization of Tasks
Use
TRM prioritizes tasks at both the task creation and task selection stages as part of its task-resource optimization .
Activities
Task Creation
At task creation , the prioritization of tasks differs slightly, according to whether the request involves a movement only or whether it also involves an operation.
Movement
Task Management queries Route Management for the different route options in reaching the destination, based on the chosen routing strategy. For more information, see Routing .
Route Management queries Resource Management for resource type qualification priorities and calculates the duration priority.
Route Management returns a priority for each route option per resource type to Task Management.
Task Management creates a task based on the route option with the highest average priority.
Task Management places the task in the Task Pool table, as well as the task and each appropriate resource type in the Task by Resource Type table.
Movement with Operation
Task Management queries Bin Management for a list of the available work centers where the operation can be performed.
Bin Management returns the operation duration for each work center to Task Management.
Route Management determines the priority of each work center based on:
Duration of the operation performed in the work center
Duration of the movement to the work center
Task Management queries Route Management for the work center priorities.
Task Management chooses the highest priority work center as the final destination of the task.
The remaining activities are those mentioned above under Movement .
Note
For an example of how tasks are created based on the route option with the highest average priority, see Task Creation .
Task Selection
At task selection , the optimal set of tasks is selected for a given resource . As opposed to task creation where only the resource types are known, at task selection the system knows which resource will perform the task.
Note
Task prioritization occurs at task selection only when a resource uses its presentation device to choose a system-guided menu option.
Presentation Management forwards the resource’s request for work to Task Management.
Route Management queries Resource Management for resource qualification priorities and calculates the distance from source priority.
Route Management returns the resource qualification and distance from source priorities to Task Management.
Task Management ascertains the Latest Starting Date (LSD) priority and retrieves the static & synchronization priority from the database.
Task Management assigns the highest priority task or task bundle to the resource, subject to execution control , via Presentation Management.
