Integration of Optimization to the Design of Pulp and Paper Production Processes - Simulation and Modeling Methodologies, Technologies and Application - page 232

In this research the solution of the optimization problem was simplified by scala-
rizing the lower level optimization problem, but this simplification has no affect to
this part of the research focusing on the business process of the design.

Fig. 1. Stakeholders of optimizing design

3.2 Stakeholders

In the model of optimizing design, new stakeholders, an optimizer and a modeler, are
added to the group of stakeholders involved in process design as illustrated in Figure
1. The optimizer is an expert of mathematical optimization whose responsibility is to
help the process designer in finding more optimal process designs. The optimizer also
needs to cooperate with the modeler in order to be able to take into account the opera-
tional aspects of the designed process. These cooperation connections with the opti-
mizer will also change the work of the process designer and modeler. Successful
cooperation between the stakeholders is a necessity for useful design optimization.
The role of the optimizer can be described as an analyst [28]. His responsibility is
not to make decisions about process designs but to produce useful information for the
designer about possibly better designs. In order to do this, the optimizer will need to
have expertise in multi-objective optimization and familiarity in process design. The
adoption of optimization also changes the roles of pre-existing stakeholders. Designer
is the decision-maker of the process design and the client of the optimizer. In optimiz-
ing design the designer has to select a part of his design problem for optimization
together with the optimizer. In addition to this, the designer also has to cooperate with
the optimizer during the optimization process and finally interpret the results and
decide how to apply them. Again, the optimizer will become the client of the modeler.
In order to adopt the new business process, all the stakeholders should gain some
advantage of the enhanced business process. The process designer gains competitive
advantage by offering design that is more tailored and more cost effective along the
life cycle of the plant. For the optimizer and modeler, the new model opens a totally
new business possibility.
