Abstract
The use of Discrete Event Simulation (DES) to support the analysis of production
systems is well-established. However, the development of new production systems
creates conditions which can cause difficulties in successfully applying this type
of simulation. This thesis investigates if and how DES should be applied during
the development of a new production system concept. A number of significant
challenges with this application and context have been identified, which are caused
by uncertainties in project prerequisites, frequent changes of the system and concept,
and limited availability and quality of input data. Accordingly, this thesis proposes
an adapted DES project methodology which sets out to overcome the identified
challenges. The adaptations include parallel and iterative methodology steps, and
a critical importance of closely involving the simulation team in the development of
the new production system concept. The proposed DES project methodology was
applied and evaluated during the development of a new production system concept
in an industrial case study. The findings from the evaluation show that the proposed
simulation project methodology can reduce the impact of the identified challenges
with an application of DES in this context. However, these challenges still exist and
have to be considered. Additionally, the proposed simulation project methodology
enables valuable feedback-loops which contribute to the development of both the
simulation model and new production system concept.
