摘　　要：针对当前发电机组检修管理系统在数据管理与分析能力上的不足,结合数据仓库技术多角度多层次、集成度高等优点,遵循电厂检修的实际要求,设计了基于数据仓库技术的机组检修决策支持系统,并采取星型数据仓库结构模型,以机组基本参数、运行维护信息为数据基础,以检修优化和计划安排为核心流程,以实用化的整数规划优化模型为计算工具,涵盖了运行数据管理、检修优化管理、系统管理等功能模块。最后,分析了该系统在开发和使用中应注意的关键环节。Based on the lack of data management and analysis ability in generating unit maintenance management system, and the advantage of various angles, multiple levels, high integration in data warehouse technology, according to the actual requirement of power plant maintenance work, the generating unit maintenance decision support system is designed. This system uses star schema as structural model, takes basic parameters and operation information as data infrastructure, maintenance optimization and schedule as the core process, integer programming optimization model for the calculation of tool, and covers operation data management, maintenance optimization management, system management, and other functional modules. Finally.combined with the practical requirements for maintenance work, the key link in development and application of this system is analyzed.
