1) The lead time of an order is made up of the actual processing time and the transition times between the work steps, which result from the waiting times, technologically-related idle, control, post-processing and transport times. The transition times can be up to 90% of the lead time. A shortening of the lead time is therefore primarily achieved by shortening the transition time.
2) An overlapping of the orders presupposes an open production. In other words, product units of an order that have already been completely processed in a production point are fed to the next production point for processing before the production of the associated total order (total lot) is completed.
3) Splitting the orders (lots) requires that several functionally identical units are available for the production of a certain part. The entire order (the entire lot) is split up into several partial orders and then processed in parallel. The reduction in throughput times must, however, be bought with a multiplication of the set-up costs.
