5.1. Non-intuitive correlation
The DT model is composed of a complex causal relationship, and a latent
effect occurs during the interface process between modules. A potential
problem is sometimes found due to the latent effect. The correlation of
simulation results included a potential problem. This is because the
results showed that if the improved maintenance policy promoted by ROK
Navy was continuously applied, the cost and the probability of mission
failure would increase. Due to military security concerns, details
cannot be disclosed. This was due to the limitations of human analytical
ability. This section explains that non-intuitive results can be
confirmed by using the DT model through an example.
