Integrated interpretive structural modeling (ISM) and MICMAC diagram for analysis of infrastructure influence in supporting submarine operations

The strategic value of the Navy’s submarine capabilities is greatly influenced by the ability of its supporting infrastructure to be able to maintain the confidentiality of submarine operations. Based on these conditions, this study aims to identify and analyze the operational readiness of submarines to increase the deterrence of the state defense system at sea. This study uses Interpretive Structural Modeling (ISM) and MIC-MAC diagrams. The ISM method is used to analyze the effect on the criteria. MICMAC diagrams are used as criteria for determining the related variables. Based on the results of the ISM and MICMAC diagram analysis, it was found that fifteen elements were divided into 4 (four) quadrants. Quadrant I (Autonomous) consists of six elements, such as ( C 1 ) , ( C 2 ) , ( C 3 ) , ( C 4 ) , ( C 13 ) , ( C 15 ) . Quadrant II (Dependent) consists of six elements, such as ( C 5 ) , ( C 6 ) , ( C 7 ) , ( C 11 ) , ( C 12 ) , ( C 14 ) . Quadrant IV (Independent) consists of three elements, such as ( C 8 ) , ( C 9 ) , ( C 10 ) . This research is expected to provide benefits to both academics and practitioners in the field of submarines and defense strategy.
