Abstract
Product configuration is an important approach in customization environments. In this study, an integrated approach is developed to improve product configuration considering product reliability, warranty and purchasing cost of components as evaluation criteria. In order to meet customer requirements, the market’s feedbacks are considered and used in the fault tree analysis (FTA) to identify product failures and defective components. In addition, reliability and total cost of each generated configuration are computed. Series and parallel systems and redundancy are considered to calculate reliability. Then, an integrated FTA and design failure modes and effects analysis approach is proposed. Risk priority number is used to evaluate each configuration option from risk viewpoint. Finally, a case study of laptop computer is used to show the applicability of the proposed integrated approach. The numerical results show that the proposed approach provides several configuration options for manufacturers by considering various decision criteria.
