Optimization of Open Queuing Networks with Batch Services

Mathematics, 2022
In this paper, open queuing networks with Poisson arrivals and single-server infinite buffer queues are considered. Unlike traditional queuing models, customers are served (with exponential service time) in batches, so that the nodes are non-work ...
