Planning Horizons
The planning horizon is the length of time a company uses as the basis of developing a plan, forecast, or schedule.
Time Bucket (MRP)
The time bucket is a period of time, usually one week, in which demand and requirements are grouped for master scheduling and material requirements planning.
