A presentation of real examples of industrial uses for formal methods such as SCADE, the B-Method, ControlBuild, Matelo, etc. in various fields, such as railways, aeronautics, and the automotive industry, the purpose of this book is to present a summary of experience on the use of these “formal methods” (such as proof and model-checking) in industrial examples of complex systems. It is based on the experience of people who are currently involved in the creation and evaluation of safety critical system software. The involvement of people from within the industry allows us to avoid the usual problems of confidentiality which could arise and thus enables us to supply new useful information (photos, architecture plans, real examples, etc.).

The EN ISO 13849-1 standard, “Safety of machinery – Safety-related parts of control systems”, contains provisions governing the design of such parts. This report is an update of BGIA Report 2/2008e of the same name. It describes the essential subject-matter of the standard in its third, revised 2015 edition, and explains its application with reference to numerous examples from the fields of electromechanics, fluidics, electronics and programmable electronics, including control systems employing mixed technologies. The standard is placed in its context of the essential safety requirements of the Machinery Directive, and possible methods for risk assessment are presented. Based upon this information, the report can be used to select the required Performance Level PLr for safety functions in control systems. The Performance Level PL which is actually attained is explained in detail. The requirements for attainment of the relevant Performance Level and its associated Categories, component reliability, levels of diagnostic coverage, software safety and measures for the prevention of systematic and common-cause failures are all discussed comprehensively. Background information is also provided on implementation of the requirements in real-case control systems. Numerous example circuits show, down to component level, how Performance Levels a to e can be engineered in the selected technologies with Categories B to 4. The examples provide information on the safety principles employed and on components with well-tried safety functionality. Numerous literature references permit closer study of the examples provided. The report shows how the requirements of EN ISO 13849-1 can be implemented in engineering practice, and thus makes a contribution to consistent application and interpretation of the standard at national and international level.

La maîtrise des risques technologiques et industriels est maintenant une exigence sociétale majeure. En effet à la suite de l'accident AZF à Toulouse, un foisonnement de protocoles et d'applications réglementaires a induit une évolution de la conception du danger et de la notion de risque, qui a conduit au passage d'une évaluation déterministe à une causalité probabiliste. Sécurité des procédés chimiques vise à fournir les outils permettant d'appréhender l'analyse du risque et l'appréciation des conséquences. La terminologie y est actualisée avec les nouveaux termes d'aléa, d'enjeux, d'intensité, de cinétique et de vulnérabilité. Les connaissances de base sont présentées suivant les récentes typologies classiques des caractéristiques des effets des phénomènes de dangers. Outre les méthodes simples et classiques d'analyse des risques (APR - HAZOP - Arbres), l'aspect méthodologique est complété par la présentation de la méthode du nœud papillon et de quelques nouvelles méthodes systémiques intégrées (MOSAR - ARAMIS - LOPA). La démarche de la maîtrise des risques est enrichie d'une revue très complète des concepts de défense en profondeur, de couches de protection, de lignes de défense, de fonctions de sécurité et de différentes barrières rarement proposés simultanément. Enfin, le contenu de l'étude de dangers est décrit d'après la base réglementaire de leur guide d'élaboration. Compte tenu de son approche systémique et pédagogique, ce livre est accessible au débutant tout en répondant aux exigences des spécialistes. Sécurité des procédés chimiques s'adresse donc aussi bien aux ingénieurs, industriels, techniciens, cadres des services publics, des communautés urbaines et des collectivités territoriales, enseignants, chercheurs qu'aux élèves ingénieurs des grandes écoles scientifiques et aux étudiants de licence, master et doctorat des universités…

Este libro es la respuesta a la necesidad creciente de encontrar una obra en español sobre un tema tan nuevo y tan integrado en el sector de Procesos como el de los Sistemas Instrumentados de Seguridad. Explica claramente y recorre paso a paso todos los aspectos del ciclo de vida de seguridad, basándonos en losestándares europeos IEC-61508 e IEC-61511 y la normativa americana ISA-84.00.01. El texto muestra la normativa aplicable, la que es de obligado cumplimiento y la que no, estudio de las Capas de Protección (IPL), diseño conceptual, los documentos que se originan en cada etapa del proyecto, qué información proporcionan, cómo se utiliza esa información, Los métodos de análisis de Riesgos ylos métodos de asignación de SIL. Se analiza la Instrumentación de Campo y lalógica con respecto a la Seguridad Funcional, los tipos de instrumentos, su instalación, su mantenimiento, así como a especificación de Seguridad (SRS), eldetalle de cada Función Instrumentada de Seguridad (SIF), cómo se verifica una SIF, qué aspectos hay que considerar en su verificación, las distintas arquitecturas y su influencia en los resultados de Probabilidad de Fallo en Demanda(PFD), Disponibilidad (A) y Fiabilidad (R)

La série Applications logicielles certifiables présente de manière concrète et critique les étapes de réalisation d’une application logicielle, un processus complexe nécessitant un travail d’équipe. Ce deuxième volume est dédié à la description des processus supports. Il en couvre les principales thématiques : la gestion des ressources humaines et de la configuration, l’archivage, la vérification et la validation du logiciel. Cet ouvrage analyse également l’impact de l’utilisation des composants sur étagère (COTS) et des logiciels préexistants sur les applications certifiables. En s'appuyant sur les définitions présentées dans le premier volume de la série, le lecteur trouvera ici une description essentielle et complète des processus supports qui doivent être mis en oeuvre pour réaliser une application logicielle.

The Monte Carlo method is a numerical technique to model the probability of all possible outcomes in a process that cannot easily be predicted due to the interference of random variables. It is a technique used to understand the impact of risk, uncertainty, and ambiguity in forecasting models. However, this technique is complicated by the amount of computer time required to achieve sufficient precision in the simulations and evaluate their accuracy. This book discusses the general principles of the Monte Carlo method with an emphasis on techniques to decrease simulation time and increase accuracy.
