This paper introduces user intervention to control simulation states during the execution of a simulation for military engagements. In an engagement simulation, it covers both a discrete event system and a continuous state system. Thus a system for the engagement simulation can have numerous simulation states, because there are lots of factors to decide states of an engagement that are derived during an execution of the simulation (e. g. detection probability, moving speed, moving path, and so on). It means both a result and progression of simulations are important outputs. Configuration of an engagement simulation scenario and expectation of simulation states, though, is hindered by the number of generate-able states. In order to solve the obstacle, the engagement simulation system should be controllable by user intervention during a simulation execution. This paper is to define objects of user intervention, and to design control processes of defined objects.

This paper describes the quality attributes of an integrated simulation software for weapon systems named Advanced distributed simulation environment(AddSIM). AddSIM is developed as a key enabler for Defense Modeling & Simulation(M&S) systems which simulate battlefields and used for battle experiments, analyses, military exercises, training, etc. AddSIM shall provide a standard simulation framework of the next Defense M&S systems. Therefore AddSIM shall satisfy not only functional but also quality requirements such as availability, modifiability, performance, testability, usability, and others. AddSIM consists of operating softwares of hierarchical components including graphical user interface, simulation engines, and support services(natural environment model, math utility, etc.), and separated weapon system models executable on the operating softwares. The relation between software architectures and their quality attributes are summarized from previous works. And the AddSIM architecture and its achievements in the aspect of quality attributes are reviewed.

순수 기계식 시스템에 의존하던 군용차량의 전자화가 진행되고 있다. 이미 소형 군용차량의 전자화는 상당부분 상용화되었으며, 점차적으로 대형군용차량으로 확대될 것이다. 군용차량의 안정적인 주행성능을 위해서는 자동변속기용 솔레노이드 밸브의 설계가 매우 중요하다. 본 연구에서는 솔레노이드 밸브에 대해 ATF온도 변화에 의한 성능변화를 정량적으로 예측할 수 있는 해석(Simulation)수법을 개발하는 것을 목적으로 한다. 연구는 자장해석소프트웨어인 Maxwell과 유압해석프로그램인 AMESim을 연동하여 진행한다. 시뮬레이션 결과 고온($120^{\circ}C$이상)과 극저온($-20^{\circ}C$이하)을 제외한 온도 영역에서 실험결과와 매우 유사함을 보인다.

This thesis provides the implementation of a simulation model for a particular Local Area Network (LAN), employs carrier sense multiple access (CSMA) bus architecture, which implements functions of the Stock Point Logistics Integrated Communication Environment (SPLICE). First, specifications of the model are identified based on the given functional specification and operating system design. Then the approach taken for modeling and programming in GPSS is discussed. Finally, the program and results of the simulation run are provided.

This paper describes a Battle Group Combat Simulation Model (called 'BAGSIM'). BAGSIM is developed to be used as an experimental tool for studies about combat modelling at battle group level. Thus it takes many of the parameters and situations into consideration at this level, and it is designed to be easily adapted to represent equivalent situations to the other more aggregated models. Further the main processes occurring in its simulation procedure such as target detection process, target selection process, firing and killing processes are verified by comparison with the existing stochastic duel models.

A gun is still one of the major weapons of a combat ship. To assess the ship's fire control capability which is influenced by tracking system, fire control algorithm, gun, the ship itself, target behavior, environment and engagement situation, simulation system for gun-oriented engagement for surface ship is needed. This paper proposes the process for designing and implementing a gun-oriented engagement simulation system using DEVS(Discrete Event Simulation Specification), which is a formalism based on the set theory. It consists of the following activities : 1) analyzing the characteristics of a gun-oriented engagement, 2) constructing the deterministic model of the combat ship of study with DEVS, 3) modeling properties of each entity showing as stochastic errors. With this process, the gun-oriented engagement simulation system is developed and applied for the combat system under development.

본 연구에서는 공급계약(supply contact)방식의 전환을 통해 군재고의 효율적인 관리를 달성하고자 한다. 이를 위해 현 육군공급계약 시스템과 수량유연성계약 시스템을 시뮬레이션 모델링하고, 4가지 불확실한 수요패턴에 대한 육군 의약품의 재고수준과 재고비용에 미치는 영향을 동적으로 연구한다. 다양한 수요패턴에 대해 수량유연성계약이 군재고 수준과 재고비용을 감소시키는 것을 시뮬레이션을 통하여 입증함으로써 군의 공급계약방식의 새로운 변화를 제안한다. 시뮬레이션을 통한 검증작업을 군 재고 시스템을 중심으로 하였으나, 본 연구 과정은 일반 기업 등에서도 충분히 활용가치가 있을 것으로 예상한다.

Every year, about 250,000 new recruits enter the military under the R.O.K military draft system. When the fresh soldier groups arrived at the Recruit Training Center, their supplies are distributed before they get basic military training. The supplies are divided by season, summer and winter. There are 14 class of summer items and 20 class of winter items, and the each class has about a few kinds of items. Totally, there are the hundreds kinds of supplies and the supplies distribution system is manually operated. However, in the current system, many problems such as spending a lot of time, manpower and high change rate due to the inaccurate distribution have been raised. This paper suggests the automated supplies distribution system to solve the above problems. We choose the appropriate facilities in the system by using the AHP(Analytic Hierarchy Process) and analyse the operating efficiency of the new system by simulation. The new suggested system shows about $39.25\%$ improvement in throughput and 3.75 times reduction of manpower compared to the current system.

With the increased reliance on M & S(Modeling & Simulation) in military training, defense analysis, and system acquisition. The credibility of M & S becomes even more critical issue in the M & S application community. In this paper, we have introduced the VV & A(Verification, Validation and Accreditation) concept of M & S for the assurance of its credibility, and proposed the VV & A model applicable to a military simulator development with the illustrative example of MSAM(Medium range-Surface to Air Missile) system simulator.
