PiM Mini Model on Costs based on Availability

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. For the availability of resources you simply sum up the cost of a resource times the number of principally available 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 or project factor with a normal factor and than select a "used...resource..." value that you just have to multiply with the cost per unit of the resource.
