  Service industries, such as ports, are attentive to their standards, a smooth
service flow and economic viability. Cost benefit analysis has proven itself as
a useful tool to support this type of decision making; it has been used by
businesses and governmental agencies for many years. In this book chapter we
demonstrate different modelling methods that are used for estimating input
factors required for conducting cost benefit analysis based on a single case
study. These methods are: scenario analysis, decision trees, Monte-Carlo
simulation modelling and discrete event simulation modelling. Our aims are, on
the one hand, to guide the analyst through the modelling processes and, on the
other hand, to demonstrate what additional decision support information can be
obtained from applying each of these modelling methods.
