In the water management literature both the normal and log-normal distribution are commonly used to model stochastic water
pollution. The normality assumption is usually motivated by the central limit theorem, while the log-normality assumption
is often motivated by the need to avoid the possibility of negative pollution loads. We utilize the truncated normal distribution
as an alternative to these distributions. Using probabilistic constraints in a cost-minimization model for the Baltic Sea,
we show that the distribution assumption bias is between 1% and 60%. Simulations show that a greater difference is to be expected
for data with a higher degree of truncation. Using the normal distribution instead of the truncated normal distribution leads
to an underestimation of the true cost. On the contrary, the difference in cost when using the normal versus the log-normal
can be positive as well as negative. 相似文献
