Modelling open networks with breakdowns, repairs and finite buffers: using an IPP departure process model

Open queuing network systems are useful in the computer industry. In this paper, a multi-node open network, with heterogeneous nodes, each node serving external as well as routed internal arrivals of jobs is considered. The nodes are prone to failures and repairs, the buffers are of finite size. An approximate performability model is developed based on an IPP departure process. External Poisson arrivals and routed internal arrivals are modelled together using an MMPP model. Results have been validated via simulation.
