Fuzzy Logic, an advanced method to support
decision-making, is used by various scientists in many disciplines.
Fuzzy programming is a product of fuzzy logic, fuzzy rules, and
implication. In marine science, fuzzy programming for ships is
dramatically increasing together with autonomous ship studies. In
this paper, a program to support the decision-making process for ship
navigation has been designed. The program is produced in fuzzy
logic and rules, by taking the marine accidents and expert opinions
into account. After the program was designed, the program was tested
by 46 ship accidents reported by the Transportation Safety
Investigation Center of Turkey. Wind speed, sea condition, visibility,
day/night ratio have been used as input data. They have been
converted into a risk factor within the Fuzzy Logic Designer
application and fuzzy rules set by marine experts. Finally, the expert's
meteorological risk factor for each accident is compared with the
program's risk factor, and the error rate was calculated. The main
objective of this study is to improve the navigational safety of ships,
by using the advance decision support model. According to the study
result, fuzzy programming is a robust model that supports safe
navigation.
