Abstract：Research purposes: Catenary is an important part of power supply equipment. Safety is ensured only by reliability optimized design.
Research methods: By analyzing the influential factors of reliability allocation, the method of fuzzy synthesis evaluation based on fuzzy mathematical theory was presented to carry through optimum allocation of catenary system in this paper. Namely, appointed reliability index is distributed rationally to subsystem of catenary system by establishing factor collection of reliability level and the weight of factor and further synthesis decision-making based on attachment degree of every factor. Both reliability of whole system and economic benefit are ensured, its arithmetic was programmed simultaneously.
Research results: It proves that reliability of catenary suspension is the biggest, secondly holding setting, orientation setting and support setting respectively.
Research conclusions: It provides a feasible method for railway department's reliability optimum design of catenary system, and need to be further perfect in the design practice.
