Queueing analysis of an optical disk based office system

The authors consider worker waiting times and throughput for an optical-disk-based document storage and retrieval system in an office environment. They model the system as a single-server queuing system having a finite number of each of two types of worker: document user and document entry. Worker think times are assumed to be exponentially distributed while job service times are drawn from general distributions; worker think times and job service times are dependent on worker type. Throughput and waiting time as a function of the number of users of each type are analyzed under a nonpreemptive rule in which document use has priority over document entry. The methodology developed to assess average delays in finite-source queuing systems with priority appears to be novel.<
