Describe finite capacity scheduling in a sentence or two. What is its role in short-term scheduling?

Finite capacity scheduling (FCS) removes a shortcoming of MRP, which is that it ignores the capacity of time buckets. FCS makes short-term scheduling more realistic because it accounts for the finite capacity of time buckets. FCS can allow almost instantaneous change, and may involve an expert system or simulation system as planning tools. Short-term scheduling is evolving into finite capacity scheduling.
