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

Table 10

Modelling of variables related to emission at the port.

Variable Name	Modelling Technique	Description
CO2 Level	TNORM	The level of CO2 emission (million tonnes/year) follows a truncated normal distribution (TNORM) with an average of 15 and variance of 2.5. The level of CO2 emission (million tonnes/year) never goes below 12 (lower bound) and 18.5 (upper bound), according to the historical data for the inland waterway port.
Level	TNORM	The level of (million tons/year) follows a truncated normal distribution with an average of 0.2, the variance of 0.005 with lower bound and upper bound of .1 million tons/year and 0.4 million tons/year, respectively.
