The data is run through the scheduler software, which produces a schedule. The schedule is then uploaded back to the JD Edwards software. The manufacturing schedule is based on weekly increments, and is accessible to company employees via access through any computer terminal. Brenco completed time studies and determined manufacturing standards in preparation for the implementation of a theory of constraint-based scheduling system. The first step is to identify the constraint in the process.
Constraints are process steps running at maximum which limit throughput.
One to three work centers that are process constraints should be selected. The second step is to exploit the constraint. The process constraints should be operated as much as possible including through lunch and break periods, and other times when the machines are not running. The quantity of changeovers should be minimized, and machines need to be kept full of raw materials to process. The scheduling software identifies orders that will be either on time or late.
