Abstract:The technical risk of complex products developing is classified as the inner technical risk of activities and the technical risk among activities.Then,based on the decomposition of activities and the risk identification of inner activities,the technical risk of inner activities is obtained with the analytic hierarchy process (AHP).Finally,from the view of risk analysis,the technical risks of the various relations among activities are categorized as the sequential relations and the dependent relations,and the identification model of technical risk among activities is constructed.The method is successfully applied to the risk identification in developing the micro-electronics equipments.
