EFFICIENCY VERSUS FAIRNESS IN PRIORITY CONTROL: WATERWAY LOCK CASE

摘要

Delay at a congested service facility, such as a waterway lock, depends on the control policy used. The shortest processing time first (SPF) policy, which is a promising priority control policy, can significantly Reduce the average delay/barge compared to the normally used first come first served (FCFS) policy. SPF tends To favor large groups of barges, i.e., tows, at the expense of smaller ones. This paper modifies the SPF policy To consider fairness among tows in queues.
