This study is on the simulation conditions of the tentative 'mobilization simulation mode'(MOBSM) and the setting option of major simulation elements. The MOBSM is a training module that practices mobilization of various institutions through a simulation computer similar to actual situations. So far, mobilization exercise(Mob-Ex) is a message simulation method, so it is necessary to convert into a MOBSM because many problems such as fragmentary and practice only by some institutions are raised. Therefore, the theoretical background and previous studies on Mob-Ex and simulation were reviewed to derive the requirements and simulated elements of the MOBSM to meet the purpose of government level exercise and to suggest the critical concepts and the direction of application. The basic requirement is to simulate the main mobilization practices by institution and provide information on the mobilization execution in a nationwide scope. The simulation elements are simulated events and flow charts by mobilization type, simulated range and level by object, simulated contents of material mobilization by institution, key simulated items, DB application, and simulated period, etc. This study will be useful for policy establishment and follow-up research for technology development of MOBSM in the future, and will accelerate the transition to practical mobilization exercise by MOBSM.

It is required to transport a considerable amount of wartime strategic materials from US to Korea via airlift operation. This study attempts to formulate the wartime airlift operation model and evaluate the airlift capability of mobilized resources, including civil aircrafts. Although an airlift plan has been annually updated by the Korea Transportation Command, it is necessary to evaluate the feasibility through simulation due to uncertainties in the process of airlift operation. Uncertain parameters are as follows; the inter-arrival time of materials in the US airfields, loading and unloading times, the distribution of aircraft's initial location at the time of mobilization order. The simulation is executed under two scenarios and the results are analyzed through a sensitivity analysis. Simulation result shows that the irregularity of inter-arrival time and the number of mobilized civil aircrafts are the most critical factors in influencing airlift capability.

In this study, the Hazard-based model to decide regional oil recovery capacity by using AHP is suggested and regional oil recovery capacity is calculated by applying the model. The simulation for oil recovery capacity by mobilization of regional oil recovery equipments is carried out to verify the availability of the model. The worst oil spill accident in Daesan Taean Pyeongtaek region, which is located in geographically disadvantageous position among the regions that the worst oil spill accident may occur, is supposed for the simulation. As a result of simulation, the quantity of oil that can be recovered for three days on the scene of oil spill accident is worked out as $15,841k{\ell}$, which can satisfy the goal of national oil recovery capacity for the worst oil spill accident, therefore the model is verified as practicable.

Recently, the Korean military has been drastically reducing its active-duty troops due to rapid demographic changes and the reconciliatory mode between the two Koreas. Under these circumstances, the wartime reserve forces play an important role. In times of war, a successful personal mobilization is critical especially in early combat stage. Previous research has been carried out using insufficient data collected only within the military and there have been limitations on empirical analysis due to changes in the designation methods for personal mobilization. This study analyzes how much of the reserve forces can be filled at the prescribed time by analyzing the transportation route of the reserve forces in wartime by utilizing military-related data and credit card usage data of the reserve forces residing in Yong-in city. The analysis showed that all reserve forces could not be called up within the prescribed time. In particular, Gangwon Province has shown results of less than 70 percent call-ups, and could cause serious weakening of combat capabilities in the early stages of the war. The main reasons could be the difference between the actual residence and the residence address and the excessive time caused by the traffic congestion.

최근 전장환경의 급격한 변화와 고도화된 과학기술로 인해 무기체계의 성능은 매우 발전되었으며 세계 각국은 고성능, 고효율의 최신 무기체계 개발에 역량을 집중하고 있다. 개별 무기체계에 대응하여 새롭게 개발된 무기체계는 기존 무기체계에 대한 패러다임을 뛰어넘어 새로운 개념과 운용방식을 요구하고 있다. 무기체계의 효과를 규명하고 검증하기 위한 수단으로 가장 적합한 것은 실제전장에 무기체계를 투입한 실기동 실험을 통해 효과를 분석하는 것이다. 그러나 무기체계 효과분석을 위해 실기동훈련을 계획하고 실시하는 것은 비용 뿐 아니라 군사력 동원면에 있어서 비효율적이고 부담이 높은 단점이 있으므로, 국방시뮬레이션 기술을 활용하여 저비용 고효율의 모의분석을 실시함으로써 계량적인 효과분석을 수행하고 수치화된 판단 근거를 제공하는 것이 보다 바람직하다고 할 수 있다. 본 고는 대대급 이하 소부대의 전장상황에서 지상군 단위무기체계의 효과 분석을 수행할 수 있는 국방 시뮬레이션 모형의 개발 방향을 제시한다.

단위 시간 동안 이루어지는 교수-학습 활동이 이루어질 때, 교육적으로 추구하는 최선의 목표는 학습자가 정해진 목표를 달성하는 것이다. 이를 위해서 학습자가 수업에 실제로 참여하는 시간을 확보하는 일은 무엇보다도 중요하다. 학습과 관련성이 없거나 높지 않은 여러 가지 변인들로 인해 학습자의 학습 시간이 침해받는 일을 최소화하기 위한 해결 방안 수립이 필요한데, 시간과 인력을 불필요하게 동원하지 않으면서 빠른 시간 내에 원하는 결과를 관찰할 수 있는 시뮬레이션의 활용이 효과적이다. 시뮬레이션 모델 정립을 통해 학습자의 실제학습시간(Academic Learning Time)을 증진시킬 수 있는 방안을 모색하고자 한다

From the simulation results, under the collaborative platform of big data based on coordination of the beer industry to mobilize the supply chain operation condition, supply chain direct logistics inventory are in a relatively stable value, and there is no zero inventory or even a serious lack of beer in the stock situations like traditional beer supply chain operation, which avoid the situation of demand information expansion caused by chain inventory levels report because of the serious lack of supply.

This study calculates the employee receives severance pay scale are paid from the company in the DC system. In addition, by utilizing the reserve growth model were studied in accordance with shortfall risk levels generated by stochastic asset allocation. For the analysis, from 2004 to 2013 using the KOSPI returns and total bond yields were simulated. Scenario 1 is when compared to the severance reserve is insufficient. Scenario 2 is the same as if toy reserve this severance pay. During one period, depending on the asset allocation of stocks and bonds was confirmed that the probability pension risk does not occur. And we suggest that members of DC pension risk endeavor with the government and companies to avoid.

This study compares and analyzes wholesale(or price-only) contract, revenue-sharing contract, quantity-flexibility contract, and channel-rebate contract in a decentralized supply chain consisting of one supplier and one retailer. By setting the parameters of each coordination contract based on the previous results, we conduct simulations using @RISK for several combinations of these parameters. Under the supply chain coordination, we evaluate the probability of successfully signing a contract and the participant in favor of each contract. As a result, the quantity-flexibility contracts is most advantageous for the retailer and the channel-rebate contracts is most advantageous for the supplier. It revealed that revenue-sharing contracts can be used more flexibly because they can be selected in the widest range to redistribute profits between supplier and retailer.
