Chaque bras de levage inférieur est articulé à une pièce mobile liée au châssis du tracteur ou automoteur agricole, de manière à faciliter le déplacem...
The design process of product development is the earliest opportunity to integrate safety into products. The term 'design for safety' captures this effort to integrate safety knowledge in the design process. Whereas, reverse engineering (RE) has been a common method to obtain design feedback and knowledge of the existing system, this paper presents...
The design process of product development is the earliest opportunity to integrate safety into the product. The term 'design for safety' captures this effort to integrate the safety knowledge in the design process. In this context, this research suggests to do 'design for safety' through two sequential methods in two parts. In the first part a meth...
Present considerations of innovative, next generation reactor concepts with improved
safety and sustainability characteristics have motivated the IAEA to launch a series of
consultancy meetings to interpret applicability and make a proposal for a possible revision of its
Safety Standards for these advanced reactor designs. This paper summarizes res...
This paper proposes an original Alternative Action Plan Generator - A 2PG, which predicts possible alternatives of the human action plans in which the human operators do not respect the safety rules. These alternatives build an anticipated feedback. Five parameters characterize A2PG. The creation of action plans is through algorithms of definition...
Improving the safety of machineries is one of the interesting research terms. One result of these works is development of safety standards offering the designers the approaches to comply with regulations. In parallel, the approaches, concepts, methods and tools resulting from research works are applied to integrate safety in design. One criticism c...
The designs of many existing and future nuclear power plants have been
enhanced to include additional measures to prevent and mitigate the consequences
of complex accident sequences involving multiple failures, and of severe accidents.
This has motivated the revision and update of the Safety Requirements for safety
assessment of facilities and acti...
Generally, human safety is taking into account at the end of the design or redesign process while the main technical choices have already done. As a result, consideration of human safety is made with the integration of material or immaterial barriers. IRAD (Innovative Risk Assessment Design) method was defined to solve this problem. Its principle i...
Une conception sécuritaire est garantie par l’intégration des aspects santé-sécurité de l’utilisateur dès le début, et tout au long, du processus de conception d’une machine. L’intégration de ces aspects dans la conception entraine souvent des contradictions entre les exigences de performance et les exigences de sécurité. Les méthodes de résolution...
This paper aims to show the importance of taking into account human factors in risk analysis. Safety analysis methods identify system failures and dangers, thus allowing risk to be analyzed. However, although erroneous human behaviour can affect the Human-Machine System, studies using safety analysis usually do not explicitly take the human factors...
In the discipline of product design, safety barriers implementation for risk reduction usually intervenes in the end of the design process, in the detailed design stage, and are rapidly increasing in variety, size, complexity and sophistication. In fact, there is no formal method to set safety requirements in the early design from knowledge abstrac...
This paper analyzes the behavior of drivers using Adaptive Cruise Control (ACC) within the theoretical framework of Human–Machine Cooperation. The study was carried out on a driving simulator. Driving task performance data and responses to a trust questionnaire were analyzed in order to examine the relationship between driver reliance on ACC and su...
Since a few years ago, the tendency has been towards increasing the number of in-vehicle Driver Assistance Systems (DAS). These systems can be more or less useful for the driving but before being integrated in a wide range of vehicles, the compatibility with the driving task must be discussed. A previous study, using on-line subjective workload ass...
Since few years, the tendency is in the increasing of in-vehicle system number. These systems can be more or less useful for the driving but before being integrated in a wide range of vehicle, the compatibility with the driving task must be discussed. A previous study, using on-line subjective workload assessment had shown the limits of such approa...
This paper analyses the links between control and cognitive control, in the case of drivers using an Auto Adaptive Cruise Control (AACC). We carried out an experiment using a driving simulator and two simulated AACCs which differentiated one another from the operating mode. It was assumed that these modes would induce different driving behaviours,...
The purpose of this paper is to analyse the cooperation between drivers and two simulated Auto-Adaptive Cruise Control (AACC1 and AACC2, respectively, with and without early warning function), which were able to adapt themselves automatically to driving style and to the environment. The AACC1 was presumed to have better know-how (KH) and know-how-t...
This paper presents the study of a particular form of human-machine cooperation in order to define and evaluate a system which is able to control the intervehicle distance according to the environment, the driver's behaviors and his/her wish to cooperate with the system. This study highlights the ACC's limits to control the distance headway with th...
Identifying the driver-vehicle-environment system can be compared to a diagnosis problem. To provide the diagnosis, some methods require an analytical or knowledge-based model of the system and others require only data-based model. Because no complete analytical or knowledge-based model of the system exist, methods of the second kind seem more appr...
This paper presents the first experiment performed in the frame of a French research national program in the ground transportation: ARCOS. The aim of this study is the development of an advanced cooperative system able to modify its parameters in function of the driver's behaviour. The first stage of this study consists in the building of an experi...
This paper presents an application of diagnosis methods to the driver-vehicle-environment system. The study aims at characterizing the driving environment on the basis of data collected on the vehicle. 14 candidates drove on a driving simulator through 4 different driving situations: driving on a motorway with a dense traffic, driving on an A road...
This paper deals with the diagnosis of driving styles and traffic conditions. Two analyses, the multiple correspondence analysis (M.C.A.) and the discriminant analysis (D.A), have been used to classify each driving behaviour among three driving styles and two traffic densities. This has been realised during experimentations carried out on SHERPA dr...
The paper shows that multiple correspondence analysis (MCA) is well suited to characterize the driver-vehicle-environment system. First, the complexity of this system is explained. Then partial models of this system are exposed followed by characterizing the methods. Among these methods, MCA has the required features to reveal what are the most rel...
