Abstract:

We investigate the impact of order-release decisions in job shop environments over a range of workflow conditions. The order-release mechanism determines which order should be released from the order pool and when it should be released to the shop for processing. Two typical opposing strategies for release timing are studied. For selection of the order to be released, three different rules are considered. The two-stage system consisting of an order pool and shop floor, which controls the capacity for each period based on the backlog in the pool is presented. The six possible combinations of strategies are compared at the same machine utilisation level, taking lead-time and the percentage of tardy orders as performance criteria.
