Designing Reliability Improvement Model Using Design Structure Matrix

摘要

As an inherent characteristic of any product or system, reliability is one of the parameters of design, construction and operation to be considered and controlled as an important criterion during relevant processes. The need to ensure the continuous and proper functioning of a product has led designers to pay special attention to increasing reliability. Therefore by coordinating all design experts and support groups throughout the implementation of product life cycle, the product development life cycle period can be reduced and value-creation of products increased. As a result, the existence of a comprehensive model is of vital importance. In this study, all industrial engineering techniques effec- tive in improving reliability are first identified and then prioritized in all phases of the product life cycle using multi- criteria decision making method. Finally, using design structure matrix, priority and posteriority of all techniques is determined in each phase and a systematic model is provided to improve equipment reliability.
