Planned Order Releases - MRP System
In an MRP system, if gross requirements exceed the quantity on hand and on order, a net requirement results. Planned orders are created to equal or exceed the net requirements in order to create a balance between supply and demand.
Each period refers to a future time. The time period, or time slot, may be a day, a week or a month. Another name for these time slots is time bucket. The size of the bucket will be discussed later.
