Modeling the blocking phenomenon in JIT environment: An alternative scenario

Queueing networks with blocking have proven useful in modeling computer systems, telecommunication systems, production systems and public services. In this paper, an alternative scenario of the blocking mechanism is presented and its pertinence to JIT systems is explained. For comparison purposes, we apply the traditional scenario of blocking mechanism to the same class of queueing systems. Numerical results show that the values of the performance measures of the two scenarios are close within certain ranges of system parameters. The presented scenario is easier to solve and can be modeled more efficiently.
