Modelling consumable resources

You can model consumable resources using the following methods:

According to the quantity of the resource being allocated, for example 400 Tins of Paint (the Quantity on Allocation modelling method).
In proportion to the amount of work on the task, for example five rooms need painting and 10 Tins of Paint are needed per room (the Quantity From Task modelling method).
Not modelled (the Non Modelled modelling method).

You can also use Quantity From Task modelled consumable resources to calculate the number of consumable resources that are required for logistics purposes. For example:

If a task uses 100m³ of concrete, if you know the capacity of concrete mixer lorries, you can calculate how many lorries are needed to bring the concrete onto site.
If a task uses 20,000 bricks, if you know the capacity of brick lorries, you can calculate how many lorries are needed to bring the bricks onto site.

You select the modelling method you want from the Modelling Type field on the Assignment tab of the Consumable Resource Properties dialog, or the Modelling tab of the Consumable Allocation Properties dialog.
