Metrics for Assessing Overall Performance of Inland Waterway Ports: A Bayesian Network Based Approach
Table 9
NPTs of the variables describing the contributor to geographical location and port accessibility.
Variable Name
Modelling Technique
Modelling Description
Distance to Logistic & Industrial Area
Arithmetic
Distance to logistic & industrial cluster is constant: 75 miles.
Distance to Major Supplier
Arithmetic
The distance between port and major supplier is constant: 50 miles.
Distance to Intermodal Connection
Triangular
The distance between the port and the intermodal connection is modelled with triangular distribution with mean, LB, and UB of 50, 35 and 65 miles respectively.
Geographical Location
Comparative Expression
Based on the historical data, if the logistics cluster, major supplier, and intermodal connection are within 75, 50, and 50 miles from the inland port location, then port has suitable geographical location for trade and commence (true state), otherwise not (false).
Port accessibilities
Boolean
We assume that 90% of the time, the port is accessible by all required modes of transportation. On very few occasions, port entire accessibility is halted by natural calamities, human error and/or cyber-attack.
