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

Table 3

Modelling of variables contributed to port facility.

Variable Name	Modelling Technique	Modelling Description
Throughput	TNORM	Based on inland port statistics, a truncated normal distribution is used to approximate the annual throughput of an inland port with an average of 20 million ton/year.
Product Diversity	Trinagular	Product diversity is approximated with a triangular distribution with minimum, most likely, and maximum of 2, 3, and 5 respectively.
Types of Terminal	Arithmetic	Types of the terminal are fixed and equal to 3 to avail the proper terminal facility.
Warehouse Area	TNORM	Warehouse area is defined by truncated normal distribution with a mean of 7,5000 m^2.
Outdoor Ground Storage	TNORM	The outdoor storage area is approximated using truncated normal distribution with an average of 40 acres.
Dock-wall	TNORM	A truncated normal distribution is used to approximate the dock wall parameter of an inland port with an average of 700 m.
Terminal Facility	Comparative Expression	Threshold for throughput and product diversity are set as 20 million/year and 2 respectively while port should have exactly 3 types of terminal to avail the proper terminal facility.
Key Facilities	Comparative Expression	The key facilities will be suitable (true) for port operational activities if the parameters of dock-wall, warehouse area and outdoor ground Storage are higher than 600 m, 50,000 m^2, and 30 acres respectively.
