The implementation of multi-attribute approach in decision making for defense sea region models

This paper discusses the concept of decision-making on the model of territorial sea defense system to resolve cases of violations in Indonesia's marine territory by foreign vessels, illegal fishing and illegal logging. The violation also shows that Indonesia has not fully monitored its marine areas by the patrol ships. The lack of Navy patrol boats owned causes mutual-conflicst in decision-making. From the three zones of the qualitative attributes, relative weight is searched by the Analytical Hierarchy Process (AHP). Then, the value of the Relative weight is converted to normalize relative weight, basic probability assignment, and the total probability assignment, so the degree of preference is obtained from the qualitative attributes. Then, the preference degree of qualitative attributes is combined with the preference degree of the quantitative attributes with the entropy method resulting a rank that shows the optimal alternatives deployment of nine zones of base stations. The result of calculation using the entropy method shows that the highest entropy value is 0.89.
