Abstract

This paper presents various measures of a port’s optimum throughput to which its actual throughput can be compared in order to evaluate its performance. A port’s engineering optimum throughput is its maximum (technically efficient) throughput that physically can be handled by the port under certain conditions. A port’s economic optimum throughput is that throughput that satisfies an economic objective. It may be either an economic: (1) technically efficient optimum throughput (based upon the port’s economic production function), (2) cost efficient optimum throughput (based upon the port’s economic cost function) or (3) effectiveness optimum throughput (based upon the port’s effectiveness operating objective such as maximizing profits).
