However, when more than one transport demand has been defined, as specific
vehicle types may be required for specific transport demands (e.g. agricultural
vehicles, buses), it is necessary to link these demands with their specific vehicle
type during the matching procedure. Windows are, therefore, opened during
matching to allow the user to link each vehicle with its specific demand, as
shown in Figure 4.14. If this were not done, the first vehicle chosen would try
to satisfy all of the chosen transport demands.

4.3.5 The Overall Matching Procedure
Once all desired demands, fuel supplies, intermittent supplies, and load
following supplies have been chosen using the procedures outlined in Sections
4.1 and 4.2, various combinations of these may be tried via the matching
window shown in Figure 4.10. There are two streams that need to be considered
here – the energy supplies and demands, and the fuel availability. For each
chosen demand set there are four demand profiles, for the fuel supply sets there
are three demand profiles and thirteen fuel profiles, and for the intermittent
supply sets there are three supply profiles. As the output and fuel use of the load
following supplies depend on the residual demand and supply, these are not
calculated until matching.
