The Optimality of Unbalancing Both Workloads and Machine Group Sizes in Closed Queuing Networks of Multiserve Queues
Article Abstract:
Although some experts feel optimal workload assignment in a production system means equalizing workload per machine, others have demonstrated that pooled servers work more efficiently than do servers working separately. The present paper addresses two questions: 1) is it optimal to equalize the number of servers in a group, and 2) is it optimal to equalize workload per server? These questions are explored using a closed queuing network model. It is found that unbalanced configurations of server groups and unbalanced workloads are better than balanced ones. Diagrams illustrate network models; graphs and tables present study results.

A Tandem Network of Queues with Deterministic Service and Intermediately Arrival
Article Abstract:
A complete analysis of delays for tandem networks of queues is discussed. The queues have deterministic service and multiple, interfering souces. The application considered is the analysis of packet delay in a store-and-forward, packet-based, data collection system. The links represent the communication channels which operate concurrently and asynchronously. The nodes represent the storage and processing devices. The joint steady-state movement-generating functions are calculated. Graphs showing the transport-delay curve are available.
