actively during the design phases. In the case that different
stakeholders are responsible for the diversity of criteria, the
tool streamlines the collaboratively set-up of requirements.
Then, after the tool has generated feasible solutions, the
stakeholders can compare different options and search for a
solution that satisfies the criteria of each individual
stakeholder. This “solution space exploration” process can
lead to three different decision making options. One option
is that the stakeholders determine that the requirements need
to be adjusted. In this case, they can re-enter the
requirements and have the tool generating a new set of
feasible solutions. A second option is that each stakeholder
has a different preferred design solution. In this case, each
stakeholder can define its own range of preferences, and that
solutions are selected at the intersections. A third option is
that no solution satisfies all stakeholders concurrently. In
this case, detailed information of the solutions performance
indicators calculated by the tool can be used to negotiate
and select one solution. Furthermore, as CAS enables the
storage and operationalization of expert knowledge, it
supports the maintainability of knowledge for future
utilization.
