abstract={When sales representatives and customers negotiate, it must be conrmed that the nal
deals will render a high enough prot for the selling company. Large companies have
dierent methods of doing this, one of which is to run sales simulations. Such simulation
systems often need to perform complex calculations over large amounts of data, which
in turn requires ecient models and algorithms.
This project intends to evaluate whether it is possible to optimize and extend an
existing sales system called PCT, which is currently suering from unacceptably high
running times in its simulation process. This is done through analysis of the current
implementation, followed by optimization of its models and development of ecient
algorithms. The performance of these optimized and extended models are compared to
the existing one in order to evaluate their improvement.
The conclusion of this project is that the simulation process in PCT can indeed
be optimized and extended. The optimized models serve as a proof of concept, which
shows that results identical to the original system's can be calculated within < 1% of
the original running time for the largest customers.},
