Which shop loading method considers both overloading and underloading of specific work centers?

Infinite loading assumes that resources have unlimited capacity and schedules jobs based solely on their due dates and priorities. This method does not consider the actual capacity of work centers, often leading to overloading, as it disregards whether the resources can handle the proposed workload.

Forward scheduling focuses on scheduling tasks from a specified start date to determine when jobs will be completed. While it aids in planning, it does not consider the capacity of work centers and could lead to overloading if resources are not sufficient to meet the projected schedule.

Backward scheduling starts with the due date of the final product and schedules tasks in reverse to determine when they should begin. Similar to forward scheduling, it does not directly account for work center capacity, which can result in overloading if the resources are insufficient to meet the demands of the timeline.
