IT (Intrusion Tolerant) technology is for guaranteeing the availability of service for certain amount time against the attacks which couldn't be prevented by the currently deployed information security countermeasures. IT (Intrusion Tolerant) technology mainly makes use of the replication of service and system fur enhancing availability, and voting scheme and GMP (Croup Management Protocol) are used for the correctness of service. This paper presents a scheme to analyze dependability of IT (Intrusion Tolerant) technology through probabilistic and simulation method. Using suggested analysis scheme, we can analyze the robustness and make a sensible trade-offs in of IT (Intrusion Tolerant) technology.

IEC 60300 series, the international standards on reliability management system are newly developed and introduced rapidly worldwide. In order to meet this fast-changing situation, it is necessary to apply them to the Korean industries effectively. It includes the establishment of the infrastructure such as documentation of Korean Standards, introduction of test equipments and test manuals, accreditation of the certification bodies and training of the specialists etc. IEC 60300 is upgraded management system of the ISO 9000 and ISO 14000. In this regard, the Korean companies which were certified with the ISO 9000 or 14000 should endeavor to find new strategies and methods to be certified with IEC 60300. This paper introduces a Quantitative method of estimating the level of the reliability management system by applying the MIR(Maturity Index on Reliability) technique. This enables the estimation of the operation level of the system and can upgrade the maturity level of it.

IEC 60300 is an advanced Dependability Management System(DMS) designed for highly qualified company. ISO/TS 16949 is an Quality Management System enforced reliability activities. It is now hot issue how to set up and implement DMS. This paper presents an approach for implementing Dependability Management System(IEC 60300) based on Quality Management System(ISO/TS16949). We analyse the difference and relationship between these two systems, and suggest an quantitative method for evaluating DMS by introducing MIR(Maturity Index for Reliability). Finally we analyse the level of reliability activities in these systems by MIR.

It is very important for the logistics business success that Third-Party Provider maintains a successful logistical relationship with customers. The important factors for the successful logistical relationship are customer orientation, service timeliness, reciprocal dependability, keeping long-term relationships, and logistics cost savings. Therefore, Third-Party Provider establishes the logistics strategy based on the reciprocal dependability with customers and the long-term of view. In addition, the logistics strategy provides the logistics services satisfying customers and saving logistics cost.

신뢰성 기술은 제품이 고장 없이 일정기간 사용할 수 있게 하는 기술로 시장점유율과 고객만족을 높이는 효과적이고 전략적인 필수 요소이다. 검사시점의 적합성에 대한 평가가 아닌 제품 및 시스템의 설계에서부터 폐기까지의 제품수명주기에 대한 신뢰성 평가를 다루는 제품의 신뢰성인증과 신뢰성경영시스템 인증 확보가 시급한 과제이다. 이를 위한 제품 수명의 평균과 분산을 효과적으로 관리할 수 있는 신뢰성 식스시그마 기술개발과 확보가 중요 현안과제이다. 정규분포를 가정한 대부분의 품질경영시스템에서의 식스시그마 접근법은 비정규 분포를 따르는 신뢰성특성과 실험계획기법 등을 고려해야 하는 신뢰성 식스시그마에서의 적용의 한계가 많다. 본 연구에서는 품질혁신 방법론인 식스시그마 기법을 토대로 신뢰성경영시스템에서 맞는 식스시그마 구축의 방향성을 제시하고자 한다.

우리나라는 비약적인 산업기술발전을 통해 선진국 진입을 눈앞에 두고 있다. 하지만 선진국 진입에 있어 크게 세 가지의 걸림돌이 있다. 첫째로는 세계시장 진입의 장벽, 둘째로 제조물책임법(PL법) 대응방안 미흡, 셋째로는 고객신뢰 및 자원의 한계 이다. 이러한 한계점으로 인하여 신뢰성경영시스템의 필요성이 대두되고 있으며 국내의 신뢰성경영시스템의 활성화는 필수 요소로 다가오고 있다. 본 논문에서는 신뢰성경영시스템의 활성화와 이를 위한 지표개발의 필요성 및 개발 방향성을 제시해보고자 한다.

As a car is a combination of a lot of components, it is necessary to consider safety and durability. Even there are lots of components for a car, the connector is one of the most important one since it connects functional electric signal. Usually automotive connector is tested under each car maker's test specification, which should have dependability characteristic. In this paper, we aim to review the current test specifications in view of dependability, and propose an accelerated life test for the automotive connector.
