This paper presents current work which deals with the certification of automatic train protection systems according to European standards and has three main sections. The first deals with the current situation as regards third party conformity certification on the basis of a reference document. The role of notified assessors and the requirements of European standards such as Cenelec 50126, 128 and 129 are discussed and the essential elements of the European high speed train interoperability directive are given. The second section summarizes the results of the Cascade project (Certification and Assessment of Safety-Critical Application Development) which is part of the Esprit III programme. This project deals with the harmonization of the various evaluation and certification approaches for safety critical software in railway applications. Its aim is to formulate a shared evaluation method to enable safety critical software to be certified by any notified assessor in a State in the European Union with the same criteria and rules, and in accordance with applicable European standards. The third section of the paper presents the Acruda project (Assessment and Certification Rules for Digital Architectures) which supplements the work on software carried out in Cascade. This project concerns the certification of hardware architectures and makes it possible to implement certification rules for the computers used to ensure the safety of train control systems. 相似文献

In the globalization era, lean initiatives and environmental management systems are increasingly implemented in the automotive industry. The aim of this report is to investigate and perform structural analysis of Lean Six Sigma (LSS) and Organizational Performance (OP). Data were obtained from 252 top management leaders in the Malaysian automotive industry. This report presents the results of the Exploratory Factor Analyses (EFA), Confirmatory Factor Analysis (CFA), and reliability analysis, which are empirically verified and validated. A set of assessment measurements of LSS and OP is expected to be suitable for their characteristics and improve their competitiveness. Thus, the main objective of the analysis was to provide additional insight into the relationship between LSS and OP by examining the effects of ISO 14001 certification as a moderator. The results indicate that ISO 14001 certification does not significantly moderate the relationship between LSS and OP in the Malaysian automotive industry. However, the OP values for ISO 14001 certified companies are higher than those without ISO 14001 certification. 相似文献
