Metrics for Assessing Overall Performance of Inland Waterway Ports: A Bayesian Network Based Approach

Table 7

NPTs of the variables describing response rate, service availability, dwell time, and transit time.

Variable Name	Modelling Technique	Modelling Description
Response rate	TNORM	Based on the inland port statistics, the response rate of inland port varies from 85% to 95% with an average of 90%.
Service availability	TNORM	At the worst possible scenario, the port operating hours are not lower than 16 hours and at the best possible the port provides 24 hours service a day.
Dwell time	TNORM	Dwell time is modelled with a truncated normal distribution with mean, LB, and UB of 3, 1, and 4 hours respectively.
Transit time	TNORM	A truncated normal distribution is used to approximate the transit time of a vessel with an average of 24 hr.
