Primitive Task Editor Help
Once an entry for a task has been created it can be fully specified through
this editor. A primitive task is a representation of some atomic (non-divisible)
agent activity, this is depicted onscreen as a resource flow, where precondition
facts flow into a task, whereupon they are transformed into effect facts.
Using this editor the following aspects of a primitive task can be configured:
- Preconditions - the resources needed for execution of the task
- Effects - the resources that will be produced upon execution of the task
- Cost - an expression given the cost of executing the task
- Duration an expression giving the time taken to execute the task
- Precondition Ordering - the sequence in which preconditions should be achieved
- Constraints - applicability restrictions on executing the task
As some of these aspects are dependent on each other, their definition is best
attempted in the order listed above.
More informtion on the use of the Primitive Task Editor can be found in the
ZEUS Realisation Guide in the description of activity TASK-1.
