The Material Transportation Capability Analysis Method in North Korea includes adversary's activities such as destruction of bridge which is one kind of choke points in the road network and surprise attack against resupply march unit. Also, the amount of damage on choke points in the road network and repair time depending on repair unit commitment must be reflected. In this study, a scenario encompassing plausible resupply transportation circumstances while counterattacking into NK will be established. Then, based on such scenario, a simulation model will be established and the result of simulation will be compared to the results of numeric example which has been used in the ROK Army. We demonstrate, through a certain Corps operation area, that the Scenario-based Simulation Model results predict the performance of resupply operation very well. Therefore, it makes sustainment planners and commanders do activities which is suitable for battlefield and should be used in the real situation. It is also a stochastic model.

네트워크를 분석하는 방법인 stochastic 기반의 community bridge node finder는 네트워크 구조의 일부 정보만을 이용하여 중심지 및 확산 경로의 유추가 가능하다. 그러나, heterogeneity 네트워크에 적용하기 어려운 단점을 보유하고 있어, 본 연구에서는 이를 개선하고자 하였다. heterogeneity 네트워크에 적용할 수 있는 community bridge node finder 방법을 개발하기 위해 네트워크의 modularity를 계측하는 방법을 적용하였으며, 개선된 방법을 통해 community bridge node를 정량적으로 평가할 수 있어 heterogeneity 네트워크의 분석이 가능하였다. 농촌계획분야 정보의 경우, 대부분 자료의 불확실성이 존재하며 무결성이 떨어지는 특성을 가지고 있는 바 본 연구에서 적용한 전염병 확산 예측 뿐만 아니라 개선된 방법을 활용할 경우 주산지 정비 거점 분석 등 다양한 형태로 이용될 수 있을 것으로 기대된다.

In September 2013, President Park Geun-hye announced her controversial "Look North" policy, of which the most salient aspect is the "Eurasia Initiative". This comprises various proposals designed to overcome existing constraints by developing new markets and creating new economic partners in continental areas from which South Korea has been alienated since the end of World War II, and this dovetails nicely with China's One Belt, One Road Initiative. The concepts of the "Silk Road Rail Express (SRX)" and the "East Sea Rim Maritime Community (ESRMC)" have also been discussed. SRX is at present a purely symbolic railroad project intended to encourage individual, cultural, trade and diplomatic exchanges. ESRMC is a model for establishing an ad hoc community to promote regional economic cooperation around the East Sea. President Park's Eurasia Initiative will provide South Korean investment for the Northeast to complement Russian plans, like the "Northern Energy Road" being built by Gazprom, and Chinese plans, like the Chang-Ji-Tu Development Plan for the North Korean port of Rajin. China's trade, as well as its energy and food supplies, pass through the Strait of Malacca and the Indian Ocean, and are thus vulnerable to interdiction by India or the US. China is therefore trying to reduce its exposure geopolitical risk by establishing a network of corridors between the Belt and the Road to provide alternative paths. The "China-Pakistan Economic Corridor" and the "China-Myanmar Economic Corridor" provide such connections, and South Korea hopes that SRX and ESRMC can become part of a "China-South Korea Economic Corridor". This concept could do much to revitalize the underdeveloped northern provinces of China and Russia's Far East, not to mention North Korea. By linking up the Trans-Siberian Railway, the Trans-China Railway, the Trans-Mongolian Railway and the Trans-Korean Railway all these Asian countries will be connected to one another, and ultimately to Europe. An interim connection between China and South Korea using a rail-ferry has also been proposed.
