춘천시는 세계적인 테마파크 중 하나인 레고랜드를 건설중에 있다. 본 연구에서는 춘천레고랜드를 대비한 시내 교통기반에 대한 분석을 수행하였다. 먼저, 레고랜드와 관련한 현 춘천시의 교통 상황을 검토하였고 이를 기반으로 잠재적인 고객 및 도착률, 도로, 레고랜드로 진입 경로에 대한 정의를 수행하였다. 교통 상태를 반영하는 평가치인 점유율을 기반으로 분석을 위한 실험을 설계하였고 시뮬레이션을 통해 결과를 얻었다. 피크시즌에 심한 교통 체증이 예상되며 특히 도로 9,11,16에서 정도가 특히 심각하다는 결과이다. 이 도로들의 차선수 증가를 통한 추가적인 실험을 수행하였으며 시내 교통상 큰 개선된 결과를 도출하였다. Chuncheon city is constructing a world-wide famous theme park, Chuncheon Legoland. In this study, analysis of the city traffic infrastructure for Chuncheon Legoland has been performed. We first reviewed the current city traffic condition with regard to the park. We then defined potential customers and arrivals, streets, and routing street sequences to the park. Based on a measure, occupation ratio, reflecting traffic condition we designed experiments for analysis and obtained results from simulation. Our results indicate that severe traffic delay is expected during the peak season and is significant especially in streets 9,11,16. We performed additional experiments with increasing the number of lanes of them and obtained improved results.

전태보,Jeon, Tae-Bo The Korean Society for Quality Management 2011 품질경영학회지 Vol.39 No.4

MIL-HDBK-217 has played a pivotal role in reliability prediction of electronic equipments for more than 30 years. Recently, RIAC developed a new methodology $217Plus^{TM}$which officially replaces MIL-HDBK-217. Sensitivity analysis of the 217Plus component models to various parameters has been performed and meaningful observations have been drawn in this study. We first briefly reviewed the $217Plus^{TM}$ methodolog and compared it with the conventional model, MIL-HDBK-217. We then performed sensitivity analysis $217Plus^{TM}$ component models to various parameters. Based on the six parameters and an orthogonal array selected, we have performed indepth analyses concerning parameter effects on the model. Our result indicates that, among various parameters, operating temperature and temperature rise during operation have the most significant impacts on the life of a component, and thus a design robust to high temperature is the most importantly required. Next, year of manufacture, duty cycle, and voltage stress are weaker but may be significant when they are in heavy load conditions. Although our study is restricted to a specific type of diodes, the results are still valid to other cases. The results in this study not only figure out the behavior of the predicted failure rate as a function of parameters but provide meaningful guidelines for practical applications.

기지/창 계획정비와 불시 결함발생에 따른 항공기 불가동 최소화를 위해 장착엔진에 추가로 보유하는 엔진이 예비엔진으로 항공기의 적정 가용도 달성을 통한 군사력 유지에 핵심적인 중요성을 지닌다. 본 연구의 목적은 다양한 군용항공기의 유형을 고려한 예비엔진/모듈의 최적 소요를 산출하는 방법을 제시하는 것이다. 먼저, 이 분야의 대표적 접근법인 METRIC과 메타모형에 대하여 각각의 개념, 특징 및 제한사항을 고찰하고 본 연구에서의 접근 방향을 제시하였다. 다음으로, 다양한 군용항공기에 대한 검토를 수행하고 이들을 총 5가지 유형으로 분류하였다. 유형별 계획, 비계획 정비에 대한 상세 분석을 기반으로 관련된 변수와 파라메터들을 도출하였다. 본 문제의 복잡성으로 인해 수식을 이용한 최적해의 도출이 불가능하며, 기지/야전/창 등의 정비로직을 분석한 후 ARENA 기반의 시뮬레이션과 OptQuest를 이용하여 최적소요를 산출하였다. 개발된 시뮬레이션 모델이 일련의 사례들을 통하여 최적해를 효율적으로 도출할 수 있음을 보였다. Spare engine plays an important role for securing readiness of military strength during unexpected fault occurrences and field/depot planned maintenances. The purpose of this research is to present an approach towards the optimal number of spare engines/modules for diversity of aircraft types. We first reviewed two representative approaches, METRIC and meta model. We then investigated military aircrafts and categorized them into 5 types with regard to the engine type and number of engines/modules per aircraft. Through rigorous investigation of planned/non-planned maintenance of each type, we drew parameters and variables involved. As known, due to the complexity of the problem, it is impossible to develop a simple mathematical model with a closed form solution. Based on the airbase operation and maintenance logic with parameters/variable drawn, we developed a simulation model using ARENA well representing real field exercises. For the optimal solution, we applied OptQuest. It has shown that the program developed generates reliable results through a set of case examples.

고장요인들에 대한 $217Plus^{TM}$ 시스템 모형의 민감도

전태보,Jeon, Tae-Bo 한국신뢰성학회 2011 신뢰성응용연구 Vol.11 No.4

$217Plus^{TM}$, a newly developed as a surrogate of the MIL-HDBK-217, may be widely applied for reliability predictions of electronic systems. In this study, we performed sensitivity study of the $217Plus^{TM}$ system model to various parameters. Specific attention was put to logistics model and its behavior has been examined in terms of non-component failure causes. We first briefly explained the $217Plus^{TM}$ methodology with system level failure rate evaluation. We then applied experimental designs with several failure causes as factors. We used an orthogonal array with three levels of each parameter. Our results indicate that cannot duplicate, induced, and wear-out causes have dominant effects on the system failures and design, parts, and system management have much less but a little strong effects. The results in this study not only figure out the behavior of the predicted failure rate as functions of failure causes but provide meaningful guidelines for practical applications.

An automated manufacturing process mechanism for string musical instruments has been designed in this study. In contrast to other manufacturing products, classical string instruments try to preserve their traditional design shapes even in these days and involve variety of wood working(carpentry) characteristics including highly skilled curved surfaces treatments. Great efforts have been put to develop an integrated and automated system for improved product quality and process control, reduced physical labors, better safety etc. They, however, have been limited to devise jigs and tools with regard to selected processes due to lack of technology and research man-powers. We carefully examined the products and process characteristics, and an automated mechanism which overcome prevailing drawbacks has been derived.
