The system is modeled as a single-server queueing system having a finite number of each of two types of worker: document user and document entry operator. 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 upon worker type. Throughput and waiting times 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.
