This study analyzes spatial density and integration of Space Syntax and Discrete Event Simulation (DEVS) of complex system theory and analyzes spatial structure by property, type and depth. The aim of this study is to secure the validity of the theoretical application. The study evaluated the correlation between spatial density and integration by setting up eight types of analysis models. In addition, analyzed the correlation of structural characteristics and approached the application of discrete event simulation of spatial syntax theory. It is confirmed that the concept of integration of spatial syntax theory and analysis using discrete event simulation are valid as new spatial analysis methodology. Also expect that realistic and concrete predictions will be possible if discrete event simulation evolves into research for space allocation and space efficiency optimization.

A distributed sewer cluster system is a cost-effective system to provide a service application for clients with reliable, scalable, available, and fault-tolerant features. In order to provide high quality services, it is necessary to evaluate service performances, tune the server system, and analyze performances. In this paper, we propose a simulator to generate workloads based on statistic configuration according to estimated application traffics, apply workload scheduling algorithms, and evaluate the simulation results. We introduce the simulator design modelling and architecture. By using flexible parameters, the simulator is able to generate various patterns of workloads with different statistics, and configure system environments such as the number of server nodes, system resources considered, and their capacities. With this simulator, we introduce two scenarios: one is to find appropriate thresholds for the best performance of cluster system, and the other is to find the suitable scheduling algorithm for workload characteristics of service applications.

Tsunami occurred by a rapid change in the ocean floor is a natural disaster that causes serious damage worldwide. South Korea seems to be out of the range of this damage, but it is quite possible that South Korea will fall within the range due to the long-distance propagation features of tsunami and many earthquakes occurred in Japan. However, the analysis and preparation for tsunami have been still insufficient. In this paper, we propose a tsunami simulation model based on cellular automata for analyzing coastal inundation. The proposed model calculates the range of inundation in coastal areas by propagating the energy of tsunami using the interaction between neighboring cells. We define interaction rules and algorithms for the energy transfer and propose a software tool to effectively utilize the model. In addition, to verify and tune the simulation model, we used the actual tsunami data in 2010 at Dichato, Chile. As a case study, the proposed model was applied to analyze the coastal inundation according to tsunami height in Gwangali Beach, a famous site in Busan. It is expected that the simulation model can be a help to prepare an effective countermeasure against tsunami and be used for a virtual evacuating training.

In this paper, we introduce the concept of web-based simulation and some reviews on the distributed simulation on the World Wide Web (WWW) and classify the features of current web-based simulation under the distributed way. And then we suggest the structure of distributed web-based simulation which can achieve parallel simulation and reduce simulation run time and show how the callback mechanism works to enable the distributions of jobs to clients with push service in Remote Method Invocation (RMI). Finally we present a prototype of distributed web-based simulation.

In this paper, a finite element dynamic simulation study was performed to gain an insight about the blast wall test details for the offshore structures. The simulation was verified using qualitative and quantitative comparisons for different materials. Based on in-depth examination of blast simulation recordings, dynamic behaviors occurred in the blast wall against the explosion are determined. Subsequent simulation results present that the blast wall made of high energy absorbing high manganese steel performs much better in the shock absorption. In this paper, the existing finite element shock analysis using the LS-DYNA program is further extended to study the blast wave response of the corrugated blast wall made of the high manganese steel considering strain rate effects. The numerical results for various parameters are verified by comparing different material models with dynamic effects occurred in the blast wall from the explosive simulation.

본 논문은 가칭 '동원 시뮬레이션 모형'의 모의 조건과 모의 요소 설정 방안에 관한 연구이다. '동원 시뮬레이션 모형'은 각급 기관이 시뮬레이션 컴퓨터를 통하여 동원실행과정을 실상황과 유사하게 연습하는 훈련용 모듈이다. 지금까지 동원연습은 메시지 모의 방식으로 단편적이며 일부 기관만 연습하는 등의 많은 문제점이 제기되어 시뮬레이션 방식으로 전환이 필요한 실정이다. 그래서 동원연습과 시뮬레이션에 관한 이론적 배경과 선행연구를 검토하여 정부연습 목적에 부합하는 '동원 시뮬레이션 모형'의 요구 조건과 모의 요소를 도출하고 주요 개념과 방향을 제시하였다. 요구 조건은 각급 기관의 동원조치 모의와 전국적 범위의 동원실행도 정보 제공이다. 모의 요소는 동원유형별 모의 이벤트와 흐름도, 대상별 모의 범위와 수준, 기관별 물자동원 모의 내용과 주요 모의 품목, DB 적용, 모의 기간 등이다. 본 연구는 향후 '동원 시뮬레이션 모형'의 기술개발을 위한 정책 수립과 후속 연구에 유용할 것이며, '동원 시뮬레이션 모형'에 의한 실질적인 동원연습으로의 전환을 앞당기게 할 것이다.

HLA is a general-purpose software architecture for distributed simulation designed to support a wide range of simulation approaches and application. The US DoD's HLA for modeling and simulation can certainly be regarded as the state of the art in distributed simulation. It is a mandatory standard for military simulation. The purpose of this paper is to describe applications of HLA/RTI in multiple domains across the manufacturing systems society. In many and large scale industrial systems, enormous data is generated, and is to be managed in an effective way. It needs a high performance common network library. Furthermore, it must satisfy the real function of system facilities as much as possible. The RTI is an implementation of the interface specification, provided as a set of services. Some applications focusing on the area of a small manufacturing system were demonstrated. The integration could be achieved using the HLA, together with interface modules for each of the subsystems. We have found that HLA/RTI are cable of meeting the functional requirements for a given system environment.
