Improvement of agree allocation method

Reliability allocation is an important step of system design. The design scheme for the system is directly under the influence of allocation results. AGREE is one major method for reliability allocation. In this paper, the deficiency of AGREE method was discussed, such as the depiction of importance and its applicability. Fault damage degree and fault influence degree were introduced. Through improvement of the traditional method, new allocation models for both serial and parallel connection systems were designed. Because of the improvement of this method, not only the allocation results will be more practicability, but also the application range will be wider. At last, an example was given, which demonstrate the validity and feasibility of the improved AGREE method.
