What could cause multiple commitments of individual capacities in capacity planning?

In capacity planning, multiple commitments of individual capacities can occur when a work center is designed with several individual capacities paired with an infinite planning strategy. This situation allows for more than one resource or capacity to be engaged simultaneously for the same task or project, thus leading to multiple commitments.

When a work center has several individual capacities, it means there are multiple resources (such as machines or personnel) available to handle tasks. If these capacities are employed under an infinite planning strategy, which does not restrict the resources for potential overloads or resource limits, it can lead to assigning the same resources to different projects or tasks at the same time. This results in conflicts as multiple projects vie for those capacities.

The other options would contribute to committing resources but do not encapsulate the full dynamic of having both multiple capacities and an infinite planning approach, which is key to understanding the complexity that results in multiple commitments.
