Abstract: |
Operations
research systems are employed to optimize the performance of logistics,
transport and supply chain management through solutions based on mathematical
models. The scope of these models is constrained not only by the analysts’
knowledge of the system, but also by the computational efficiency of the
solution. This re- striction can lead to a gap between
mathematical models used for solving from conceptual models derived from
empirical situations motivating the solutions. This paper claims that
simulation models may be employed to ana- lyze and evaluate the effects of the resulting model incon- gruence. To this end,
two types of model incongruence are differentiated, compositional and
structural, and two levels of effect are considered separately, short-term
and long-term. The concept is illustrated by examples from airline revenue
management: A simulation system based on a discrete-event model with multiple
agents is used to analyze the effects of parallel flights, competition, and
fluctuating demand. |
