Abstract

Decision-making is the most critical phase in Observe, Orient, Decide, and Act (OODA) defense decision
cycle. If the decision made is correct regarding the current situation, then it can minimize the possibility of loss.
The contradiction situation will occur if the incorrect decision is made. The correctness of the decision depends
of the quality on information delivered from Orient(ation) phase that will be used as the basis for decisionmaking.
Meanwhile, in defense applications the process of decision-making plays a very important role
especially if the time is the most affecting factor. Such an application is nation defense system in defending our
country’s nation sovereignty in air, sea, and land. Therefore, the faster the decision is made, the earlier the
system can perform anticipations to any nation defense intrusion. For this purpose, in this paper we address the
utilization of A3S (Arwin-Adang-Aciek-Sembiring) information-inferencing fusion for accelerating the
information processing and obtaining good comprehensive information quality that will be used as the basis for
strategic decision-making for nation defense.

Keywords: A3S, information-inferencing fusion, nation defense, OODA, strategic decision-making
