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.
