It can be defined as a series of time intervals specifying the types of order changes that are allowed. Time fences can be categorized as –
1. Demand Time Fence (DTF) – In this type, there is a designated period in which the MPS is frozen. The DTF starts with the present period, extending into the future, with relatively few periods. In demand time fence, freezing the MPS means not allowing any type of changes to the existing schedule.
2. Planning Time Fence (PTF) – Involves, a designated period during which the master scheduler is allowed to make changes. The PTF starts after the DTF ends and extends further into the future.
