太原理工大学硕 士 学 位 论 文 摘 要 派送调度问题是物流管理领域中一个重要的课题，是大型 超市集团、大型零售连锁店、物流派送中心及工业生产企业共 同存在的问题。随着跨地区、跨地域的经济活动日益加强，迫 切要求解决物资流通当中合理调度运输工具的问题来有效实现 企业生产计划、减少物资库存，从而提高工商企业的生产效率。 目前对于派送调度问题的研究主要集中在对运输工具的配置和 静态调度领域，这些研究工作已经取得了丰富的成果，并且研 究结果也主要应用于决策和管理方面。但是对于运输工具运行 情况变化和派送任务动态产生和调整关注较少，同时，在线派 送调度的计算机系统产品也较少-Taiyuan University of Technology master"s degree thesis Abstract delivery scheduling problem is the logistics management field an important issue, is a large supermarket groups, large retail chains, logistics distribution centers and industrial production enterprises to the problems that exist. With trans-regional and cross-boundary economic activities increasing, it is urgent to address the flow of goods among them reasonable means of scheduling problems to the effective realization of production plans to reduce material inventory, thereby improving business productivity. Current scheduling problems for the delivery of concentrated mainly in the transport and distribution of static scheduling field

本文基于遗传算法思想，采用浮点数矩阵表示编码，在遗传算法的进化过程中加入一定的约束条件等方法，探讨了网络结构的设计和学习。经实例分析，在用于建立大坝安全监控预报模型的前馈神经网络设计中，该方法在满足一定约束条件下，能同时有效地寻找合适的网络结构和相应的参数(神经网络的权值和阈值)，且在精度和速度上都有较大的提高，为实现实时在线分析评价大坝的安全性态提供了有力的技术支持。-Based on the genetic algorithm, using a float matrix coding, Genetic algorithms in the evolutionary process to be bound by certain conditions, to explore the structure of the network design and learning. By analyzing the examples used in the establishment of dam safety monitoring forecasting model of neural network design, The constraint in meeting certain conditions, can effectively find suitable network structure and the corresponding parameters (the neural network weights and thresholds), and the accuracy and speed have improved greatly. To achieve real-time online analysis and evaluation of the safety of the dam states provide strong technical support.
