OPS.8.1:5.3 - Waiting for an event that cannot consume the resource

An operation completes a job inside a machining loop. The remaining customer acknowledgment will use a separate administrative service, and the operating arrangement excludes any further use of the machining loop for this job in the horizon under consideration. The next eligible part has the required resources and fits the loop’s release rule.

Keeping the machining-loop card until that acknowledgment would postpone the part without protecting any machining work in the stated horizon. Return the card at the loop’s completion and retain the customer’s outstanding acknowledgment in its own account. If inspection can instead return the part to that machine, this premise is lost and the release decision reopens.
