This paper describe the ongoing work jointly between INRS and LCFC/ENSAM to take risk prevention into account in the specification drawn up when considering buying or designing work equipment (special machine, individual workstation, assembly line, etc…). The methodology is based on the functional need analysis and the concept of work situations as defined by INRS in their previous research work. The aim is to bring together the "user" and the "designer" in a dynamic of dialogue, in order to define the main work situations and not only the technical system. An overview of the problem is first described, followed by a brief review of methods currently in use. We then describe the different steps involved in the proposed methodology, before examining the results of a case-study application to a milling machine in which the benefits of such an approach and its acceptability by SME/SMIs are assessed.

Human in the factory is one of the main themes of the Factory of the Future, in this context the aim of this paper is to present the new issues for workers safety and the integrated design concepts or methodologies which have to be taking into account. New paradigms come into being: the uncertainty of the demand in terms of products as well as production rate, product customization, integration product / service, the manufacturing processes are not fixed, so the manufacturing times cannot be foreseen, reconfiguration of machine tools as manufacturing systems, space organization, autoorganization, planning …, new technologies are implemented: robots, plug and play devices, virtual / augmented reality, sensors, OPC standards, connected objects,… Several tasks are performed by the workers, the robots or in collaboration. The workers are place in the center of the Factory of the future but this concept introduce hazard events, problems of health and safety (physical or cognitive tasks, fatigue, stress, space or time organization, interfaces Human-robot, to take into account of the different life situations…). So the aim of the paper is to present studies carrying out in order to propose to the machine or manufacturing systems designers as well as production managers structured methods, models, tools in order to get safe working situations in the frame of the factory of the future paradigm.

The aim of "integrated prevention" is to conduct a preliminary risk analysis in order to achieve a lower level of risk in the design of future work equipment. Despite the many safety documents that exist, many companies, particularly SME/SMIs, do not yet apply these safe design principles. Integration of safety in the design process is mainly based on the individual knowledge or experience of the designers and is not conducted in any formalized way. In order to answer to this problem, this paper presents a methodology to involve engaging stakeholders in dynamic dialogue and a framework so that they may together define the information necessary for implementing safe design principles during the functional specification. The proposed methodology has been validated to industrial case.
