The bureaucratic organization, to be specifically, has the exactness to deal with the complexity, because it is based on the rational principles, and comes by rational calculation; It has the stability because it is based on the stable rules and hierarchy structure; It has the "reliability" on implementation of administrative goals, because personal factors are removed, the probability of making mistakes is minished under the strict "discipline" and appointment of qualified employees.

具体地说，在应对复杂性上，官僚制组织是按照理性的原则建立起来的，其组织分工和工作程序都是经过理性算计的，更具有&精确性&；以稳定的规章制度和稳固的科层制结构为基础，具有&稳定性&；由于排除管理中的人格因素，严格按照&纪律&来推行工作，就相对减小了工作出错的概率；任用经过培训的合格人员，按照专业分工将复杂的事务分解开来，因而在实现规定的行政目标方面，具有&可靠性&。

The quorum cluster including only three quorums is a small quorum system; every two quorum clusters intersected only one quorum. Circle quorum system used self-adaptive fault-tolerant protocol, which decided to use voting protocol or mutual exclusion protocol based on the failure probability and number of points of one quorum.

Circle Quorum系统采用了自适应容错协议，根据quorum内部节点的非等失效概率和失效个数决定采用选举协议还是互斥协议。quorum中所有节点组成选举quorum，其中，具有高可靠性的若干节点组成高性能响应子quorum。

First, it diagnoses and analyses the maglev train's suspension system and traction system by applying the FTA and fuzzy FTA method. Furthermore, it presents the new way to solute the diagnosis searching arithmetic by building the searching matrix based on the factors such as components' key weightiness, faults happen probability, searching cost. Then it can get optimal searching sequence for seeking the reason to the faults. Second, it builds the train's rank evaluation model based on multiple hiberarchy neural networks, after it takes the strategy that set the component diagnosis and whole train fault rank evaluation into two steps. Third, it deeply analyses reliability of the maglev train's power system with function-correlated feature, by the method that combining the FTA with the Markov model. Finally aiming at maintenance ahead of the fault, it proposes the blue print for the maglev train's maintenance. What's more, it introduces the design and realization to recorder for the train run data in detail.
