This paper presents a methodology for selecting performance indicators
for evaluating a port's performance with respect to its economic (rat
her than its engineering) optimum throughput. performance indicators a
m choice variable for optimizing the port's economic objective(s) and
include the port's price and operating options (for differentiating se
rvice). If changer in these indicators have opposite effects on port p
erformance, a single (or overall) performance indicator is recommended
for evaluating a port's performance.
