when applicable. The design data should be transferable to optimizing tool as well as
the models that the modeler has created. The support for representing the alternatives
to the designer is not that critical, because that document should be kept brief and
simple.

4 Assessment of the Model

In this chapter, the business process model of optimizing design is assessed through a
small-scale case study. This case study was carried out as a part of a wider research
project and the results of the mathematical solution of the BLMOO in this case can be
found in our partners' publications [30-33]. The case was evaluated by internal review
and expert interviews.

Case Study

Case Design Problem. The design task in the case study was to dimension six storage
towers of a part of a paper-making process and to guarantee the runnability and stabil-
ity of the process. The dimensioned storage towers include TMP (thermo-mechanical
pulp), chemical pulp, wet broke, dry broke, clean water and 0-water. The design prob-
lem is illustrated in Figure 3 and further explained in [31].
