Requirements determination is a procedure used to determine the material quantities required to implement the planned production plan. The system calculates the requirements for time, material and quantity resources.
If the program oriented (deterministic) requirement determination is used, the future consumption is determined with the help of the current production plan. If the company has a part usage plan, you can split the finished product into its individual parts and set up a dependent requirements plan.
This reveals the exact quantities of the individual raw materials or assemblies.
The consumption-oriented (stochastic) demand determination is based on the demand for the necessary materials in the past. This is used to determine consumption in the future.
