A resource network describes the physical links between resources such as processing units of a line (vessels, reactors). It describes the flow of materials through a line or plant.

You often have to use processing units in a specific sequence. To specify the sequence in which the resources are used, you can define predecessor and successor relationships between resources in the form of resource networks.

If several resources are available that can be used for similar purposes, it is a good idea to decide which ones to use just before production begins. For this purpose, you can define a planning resource that is only used for planning and represents several resources that can be used in the same way.

You use resource networks in process planning when you want to specify in which sequence the resources can be used in production.

Resource networks are used in the process order during resource selection.
