5.3.1 required 26 s to determine admissible project roadmaps and to calculate the corresponding value contributions.
On a high level of abstraction, the planning model considers an organization's status quo, admissible project roadmaps, and improved status quo candidates that can be reached by implementing admissible project roadmaps (Fig. 1).
The experts already expected a big amount of admissible project roadmaps but were really surprised about the factual amount.
Another driver of the problem complexity is the amount of available projects, which increases the amount of admissible project roadmaps over-proportionally.
To restrict the set of admissible project roadmaps, the planning model allows the specification of interactions among projects and domain-specific constraints that project roadmaps must not violate.
To reduce this complexity, it is important to include only those projects that already passed the first three stages of Archer and Ghasemzadeh's (1999) PPS process and to consider all the known constraints in the prototype, as these considerably reduce the amount of admissible project roadmaps.

Project interactions and constraints determine which project roadmaps are admissible.
The model is formulated as a bi-objective, mixed-integer optimization problem with constraints on project costs and on the types of improvement combinations admissible at project sites.
This case led to about 2.70 million potential project roadmaps whereof about 2.46 million project roadmaps were not admissible due to the underlying interactions and constraints.
This is admissible.
What isn't admissible, then?
