Abstract

The army of republic of korea have been continued to transform their logistics support system structure for better efficient logistics support system in preparation for the future environment. Logistics system has supply network structure which is connected by various units and supply network structure received attention as a factor of success of supply network. Many researchers have continuously researched inventory management, transportation or economy factors for supply network, but such a study on the one in military supply network structure analysis is still slower than the study of analysis of other factors until now. In this study, we identify military supply network structure influence factor by application of social network analysis method which is used broadly and analyze co-relationships between supply network structure influence factor and valued APL(average path length) as a criteria of efficiency of military supply network. By this study it has value of military supply network influence factor identification for the better military supply network fabrication.

한국군은 군 구조 개편 및 병력 감축 등 변화될 미래 전장 환경에 대비하여 보다 효율적인 군수지원 체계를 갖추기 위해 군수지원 체계 구조 개편을 진행하고 있다. 본질적으로 군수지원 체계는 다양한 규모의 부대가 상호 연결된 공급네트워크 구조를 가지는 특성이 있다. 이러한 공급네트워크의 구조는 공급네트워크의 효율성을 좌우 할 수 있는 요인으로 주목 받고 있다. 그동안 군 공급네트워크와 관련한 연구는 재고관리, 수송, 공급사슬 관리 방법론, 물류비용 측면에서 폭 넓고 다양하게 연구되어 왔으나, 군 공급네트워크의 구조 효율성 분석에 대한 연구는 상대적으로 미진한 실정이다. 따라서 본 논문에서는 군 공급네트워크의 구조와 효율성 사이의 상관분석을 수행하여 군 공급네트워크 구조의 어떤 특성이 효율성에 영향을 미치는 요인이 되는지를 식별하는 연구를 수행하였다. 이를 위해 먼저, 최근 폭 넓게 활용되고 있는 사회연결망분석 방법론을 사용하여 군 공급네트워크의 구조적 영향 요인으로 연결, 인접, 사이 중앙성 값을 측정한다. 측정된 중앙성 값은 군 공급네트워크의 효율성 측정지표로써 측정된 가중 평균경로거리와 회귀분석을 수행하여 상관관계를 분석하여 어떠한 군 공급네트워크의 구조적 영향 요인이 효율성에 영향을 끼치는지 식별한다. 본 연구는 향후 발전적인 공급네트워크 설계를 위한 영향 요소를 식별하였다는데 의미가 있다.
