Load-oriented order release

from Wikipedia, the free encyclopedia

The load-oriented order release (BoA) fulfills a partial function of the production control . In contrast to the "classic" order approval, production planning is divided into the sub-steps of order selection and approval check . A prerequisite for the BoA is a previous capacity calculation. Their result, the total capacity required to complete the upcoming orders, is the basis of the BoA.

Order selection

An urgency check is carried out within the order selection. This is done through a backward scheduling (backward scheduling ) of all orders, i.e. by determining the latest start dates for the start of production with the help of the planned lead time. All orders that start within the so-called anticipation horizon are classified as urgent and forwarded to the approval test, provided that the materials and workshop stocks required for them are available. All other orders are postponed until the next planning run.

Approval check

The orders that were declared urgent in the previous step now go through a debit calculation. For each capacity unit it is checked whether the maximum load is exceeded. The decisive factor for this is the so-called load limit . Only those orders are released for the respective workshop that can be processed within the load limit.

target

The aim of the BoA is to release only as much work as can be worked off in the next period. This should reduce workshop stocks and improve clarity. Through better clarity and less control effort within the workshop, the throughput times can be reduced.
