Abstract
SUMMARY The purpose of this paper is to illustrate a new technique useful in modelling complex production systems—GERT network analysis. The primary contribution of this paper is to describe how complex production systems with queueing characteristics can be analysed using network techniques. Using this approach, a wide class of production systems can be easily represented in graphical form and analysed using a FORTRAN based simulation programme hereafter known as GERTS III-Q. Each production model is constructed by drawing a queueing network composed of directed branches and logical nodes, and the analysis phase is implemented through the use of GERTS III-Q. The input to the programme iB a description of the network in terms of its nodes and branches, along with control information for setting up the simulation conditions. The objective of GERTS III-Q is to provide an easily under-stood, rapid access analysis tool useful in studying large complex production networks which possess queueing characteristics.
