현재 기업에서는 제품인증과 경영시스템인증의 신뢰성 확보가 중요한 과제이다. 이는 제품개발 중심에서 제품 및 프로세스의 통합 개발 중심으로 연구의 필요성을 제시 해주고 있다. 따라서, 정적인 제품인증에서 동적인 시스템인증의 필요성이 대두되면서 신뢰성경영시스템(DMS; Dependability Management System; IEC60300)이 요구되어진다. 제품개발의 프로세스에서 발생되는 신뢰성 문제점들을 해결하기 위하여 트리즈(TRIZ ; Theory of Inventive Problem Solving) 기법을 활용하였다. 본 연구에서는 창의적 문제해결 방법론인 트리즈기법을 활용하여 신뢰성경영시스템에서 제품 및 프로세스 통합개발(IPPD; Integrated Product and Process Development)을 하고자 한다. 결과적으로 창의적 신뢰성경영시스템(CDMS; Creative Dependability Management System)을 제품 및 프로세스 통합개발 모델로 제시한다.

A systems engineering is an interdisciplinary engineering management process that evolves and verifies an integrated, life-cycle balanced set of system solutions that satisfy customer needs. This work describes analysis of. the defense R & D programs applied systems engineering approach. FA-18E/F and NSSN defense acquisition programs are adopted for the case study. Those two programs is performed by IPPD, which is one of the systems engineering management techniques. From the analysis results, implementation considerations of domestic defense R & D programs are presented.

A System engineering is a management technique that simultaneously interates all essential acquisition activities through the use of multidisciplinary teams to optimize the design, manufacturing, business, and supportability processes. This work describes two case studies of the defence acquistion prigram applied SE. It is presented a general understanding of SE and perspective of SE applications for defense acquisition process.

Influence of rubber composition on migration of antiozonants to the surface in ternary rubber-based vulcanizates composed of natural rubber (NR) styrene-butadiene rubber (SBR), and butadiene rubber (BR) was studied. Of the three rubbers, contents of two rudders were same and only the other one content was different (variable rubber) IPPD and HPPD were employed as antiozonants. Migration experiments were performed at $60^{\circ}C$ for 21 days and outdoors for 4 months. Migration rates of the antiozonants increase by increasing the content ratio of the variable rubber in the vulcanizares from NR/SBR/BR=1/1/0.2 to 1/1/1 and then decrease with an increase of the content ratio of the variable rudder from 1/1/1 to 1/1/5. Migration behaviors of the antiozonants in the ternary rudder-based vulcanizates depending on the rubber composition were explained by the intermolecular interactions between rubber and antiozonant, by the solubility difference of the antiozonants for the rubbers, and by the interface formed between dissimilar rubbers in the triblends.

In this paper, we have proposed an integrated aircraft development environment which can support virtual design and development for Systems Engineering and IPPD(Integrated Product and Process Development). We have also proposed the ViMS(Virtual Mockup System) which can perform a system design review on an integrated aircraft development environment. The ViMS is an integrated virtual design support system with immersive design review functionality to make a virtual mockup instead of a physical mockup through the virtual reality technology. The functionality of the ViMS consists design data management, design technology, design verification, and design assessment. We have described the detailed development artifact, case studies and conclusions of using the ViMS functionality.
