Designing Product Reliability based on Total Product Lifecycle Modelling

Due to the rapid progress of technology and severe competition in market, recent industrial products are required to exhibit high quality and functionality. At the same time products are required to be environmentally conscious. Therefore it is important to achieve appropriate product reliability with minimum resource consumption. In the total product lifecycle there exist various kinds of disturbances which may deteriorate product quality and functionality. A reliability design method is proposed based on prediction of product behaviour deterioration and its influence on product functional failure. Effectiveness of the proposed method is evaluated by mechatronics product design.
