The Researches on the Optimization Reliability of Logistics System

The reliability of logistics system has a great influence on the society and the enterprises.A logistics system is a huge system contained many logistics units.Firstly,the paper studies the logistics unit's reliability and it's measurement method.And then the logistics system's logic structure and the influence between the system logic structure and the system reliability are analyzed.At the last,the paper provides a model to optimize the logistics system's logic structure under the limitations of logistics capability,logistics cost and system reliability.
