| 摘 要： | 研究了分布式并行遗传算法的智能组卷问题。设计了在校园网范围内的分布式Web服务的组卷系统，通过多线程的软件结构实现了Web服务之间的相互调用及反馈机制，采用基于Base64的预先基因压缩方案来提高SOAP性能。仿真试验证明了分布式Web服务的组卷系统不仅可以极大地减少组卷时间、具有良好的容错能力，同时也能一次生成多套试卷，为构建B/S模式下的机器考试系统提供了依据。

| Abstract: | Supply chain risk is the key factor which affects supply chain practice application, and accordingly supply chain risk management becomes the important content. Applied fault tree analysis and fuzzy theory to analyze supply chain risk. Built fault tree of supply chain failure risk. The fault tree was made up of supplier, manufacturer and distribution dealer. Analyzed the failure reasons of every part. Designed the fuzzy operators of normal fuzzy function. Expounded the computation methods of supply chain risk. Presented a supply chain risk instance. Quantified and computed every events failure risk. Finally, ascertained the risk rank of supply chain failure. |
