Abstract: According to the question of Logistics Service Supply Chain（LSSC） system, a diagnosis method is proposed for LSSC reliability based on Fault Tree Analysis（FTA）. The three-tier logistics services supply chain made up of an integrated logistics, logistics subcontractors, manufacturers constitute are taken as the research object, the general diagnosis model for LSSC reliability is established. By examples, the paper constructs the FTA model of reliability diagnostic for LSSC, solves the minimal cut sets and importance of the FTA model, and obtains the fault mode and critical fault factors of LSSC system failure.

Key words: Logistics Service Supply Chain（LSSC）, reliability, Fault Tree Analysis（FTA）, fault factor
