Abstract
In the context of industrial competitiveness, taking into account the process design throughout the product life cycle is inevitable, from the expression of the need to recycle, the capitalization and knowledge management increasingly a target much sought after companies because of increased knowledge. Indeed, during the approval phase and use studies and scientific researches make have generated knowledge especially that concerning the reliability of system components. In this context, the capitalization and reuse of knowledge are necessary and have a particular interest in design and particularly in the preliminary design phase. Studies are already completed suggest a design process ranging from the need to solve the problem. At each phase of the process, structural characteristics are defined by the designer through the available knowledge already capitalized to make choice of component and their arrangement. This article proposes integrating the analysis of system reliability in this process. The objective is the use of knowledge in the vision safety and hazards of operating through the study of reliability and decision making for the selection of solution.
Highlights
The conventional design process based on an iterative procedure is structured in successive phases, allowing to converge to valid solutions through trial-error testing [1]
We rely on a preliminary design approach based on the use of knowledge already capitalized [4] while incorporating a reliability analysis
The accuracy of such a reliability study depends on the depth and level of decomposition, for example, a wind turbine is a complex system, the study of its reliability depends on the mastery of the failure rates of its components during time
Summary
The conventional design process based on an iterative procedure is structured in successive phases, allowing to converge to valid solutions through trial-error testing [1]. The knowledge capitalization used and applied during the design process is worthy to be optimized if necessary To make this task successful, its structure and its organization have become a priority to formalize knowledge and reuse. One of the important goals of the present research work is to bring back this knowledge to the stage of preliminary design so that they could be used as criteria for decision in the solutions choice. This approach will be applied to a wind turbine system with a horizontal axis. Wind turbine mechanism belongs to structures whose availability ratio is weak, further, their maintenance is generally difficult and costly
