Abstract

Operational Analysis is a new technique utilized for modelling FMS. There have been surprisingly few studies in which FMS performance predictions from the Operational Analysis have been compared with actual measurements or simulations. This paper investigates the role of Homogeneous Service Times assumption, which is the most restrictive hypothesis of Operational Analysis. A simple example shows that this assumption can be responsable of high errors in the performance measures. A case study is considered to clarify the influence of the homogeneity hypotesis. The simulation shows that the errors in the performance measures, predicted by Operational Analysis, can be higher than 20%.
