Document Summary

The time it takes to complete all process steps from time of arrival to time of completion, including the wait time. Example: the first unit produced experiences no wait and would have a throughput time equal to 57 seconds. Inventory that is no longer raw material but has yet to become a finished product. Wip build-up occurs due to line imbalances. The factor that li(cid:373)its productio(cid:374) a(cid:374)d co(cid:374)strai(cid:374)s the syste(cid:373) s output rate. Example of bottleneck sources: slowest operation step, limited labor resources, and limited equipment resources. Bottlenecks set a ceiling on the rate at which units move through a process and thus determine the cycle time for the process. Cycle time is the time between completions of successive units (assuming there are readily available inputs) To determine the cycle time for the process, the bottleneck must be identified. Output rate is the number of units that can be produced per unit of time.
