Abstract: The paper discusses some communication problems that occur under ergonomists, designers and design tools. A project of a platform of ergonomically knowledge is brought out. Present computer aided ergonomics concentrates on analysis and evaluation in the later design stage. The technology of computer aided ergonomics for the full life cycle of the industrial design is presented. Also, there are described the key  technology at every stage in the design process. Finally, a prototype system and some examples of our research prove relevant scientific content of our research during a CNCSIS contract (type A): "Product and Production Systems Ergonomics Design for Increasing Their Safety and Quality During Their Whole Life Cycle".
