Reliability analysis will have a major influence on the design, if it is applied during the conceptual design phase. This will result in more reliable and less expensive structures; a structure that is reliable in concept is less expensive than a structure that is not reliable in concept, but is improved in a later phase of the design process. The introduction of reliability analysis in the conceptual design phase will have important consequences for the design process. The designer and risk analyst would have to work closely together and the risk analyst has to make fault tree analyses for many design solutions, increasing the cost of the design. Automation can make the analysis less complex, can reduce the time of an analysis, and can prevent errors. An implementation in software can take over complex parts of the analysis from the designer and risk analyst, and it can execute these tasks much faster and more accurate. If the designer can execute the analysis himself, he does not depend on the availability of a risk analysis expert. Then, he can immediately decide if and how the design needs improvement. Also, the designer can optimise a structure by analysing a number of concepts. Thus, reliability analysis can be applied in many more cases than before, which will lead to better designs. This article discusses the role of reliability analysis in the design process of drive systems at the Mechanical Engineering Department of the Construction Division of the Ministry of Transport, Public Works and Water Management. It gives an abstract description of the functions of a drive system to find an automated reliability analysis method.
