DISPATCH LIST

If we have several jobs or manufacturing orders to be run at different workstations utilizing a number of workers, we should have a method of selecting and sequencing the jobs to be executed at specific workstations and also for assignment of the same to the workers. This method is referred to as dispatching.

The planner normally generates the dispatch list daily for every work center. For every operation in the manufacturing order the dispatch list contains exhaustive information on priority, location, quantity and capacity requirements.
