Current behaviour

In determining the ordering strategy after sorting (based on neccesary space and cost) a pairwise check is made to see which measures should be kept. This check should not only be pairwise, but take all following measures into account. In the end the cheapest option should always be prefered!

Furthermore, the order should be based on the cost/km including surcharge factor!

	Cost	Space	Resultaat	Verwacht
