Final answer:
The manufacture of milk products is an example of a continuous process, where operations run nonstop and without interruption, unlike the batch production of wedding invitations or the project-based production of jet aircraft.
Step-by-step explanation:
An example of a continuous process in production is the manufacture of milk products. Continuous processes involve operations that run 24/7 without interruption. Unlike the production of items such as wedding invitations or jet aircraft, which can be considered job shop or batch processes with distinct start and end points for each product, milk product manufacturing typically involves a nonstop operation.
In contrast, wedding invitations and jet aircraft are more aligned with batch production (wedding invitations) and project-based production (jet aircraft). For the former, a certain number of invitations are made based on orders, and for the latter, each jet is manufactured to specific requirements, which is not a continuous cycle.
