PiM Mini Model on Costs based on Availability by Kai Neumann

This mini model shows one of two ways to calculate costs within PROCESS-iMODELER models. Costs can be either as shown in another model the directly associated costs or like shown here the costs of the availability of the resources.

The use of level resources can either be equally their principal availability or their use. For this you can use the possibility to connect a process...

So here is the start of a collaborative model.  Please ask for any further assistance / guidance using the comment functions on kno...
