Abstract: Flexible
manufacturing systems are formulated as an open queueing
network. In the model, machines process jobs with exponentially
distributed processing time, carts route jobs to workstations
according to a Markov routing policy with exponentially
distributed routing timeand blocked jobs are treated in
accordance with a new block mechanism, called "FMS
block" mechanism. It is shown that the equilibrium state
distribution of the model has a product-form solution. Based on
the product-form solution, system performances can be easily
measured.
