This leads to metrics, the measures of the spaces
The most typical measures of a task are the time measures, i. e. portrayals which depict distances which require equal time for covering them depending on the means of transportation and on the difficulty of the road. This relativity of measures is present in all varieties of systems, and not so much in the portrayal itself as in the approach of solution, such as in cost and profit optimisation tasks. In these spaces, however, the given geometries are characterised by rules that are different from earlier geometric traditions, such as those relating to the sum of angles in a spherical triangle, or the equalities or characteristic inequalities of transformation directions (there and back) in other process spaces.
