中文摘要：

对集中供热系统的优化设计方法进行了研究,提出了适用于集中供热系统的两级优化规划方法,即第一级的布局优化和第二级管网的多目标优化方法。根据最优化理论建立的布局优化和管网系统多目标优化通用模型及采用的求解方法,适用于所有具有＂管-站＂网络特征的系统。运用方法对辽河油田振兴区集中供热改造工程进行了优化设计,取得了较好效果。对改进供热系统设计水平、提高企业经济性具有指导意义。

英文摘要：

The optimization layout of heating system is studied.A suitable two-stage optimization layout method is raised which is made up of the position optimization（the first stage）and the multi-objective optimization of ductwork（the second stage）.Not only the position optimization model and the multi-objective optimization model based on optimization theory,but also the solution adopted in this paper is fit for all system with ＂duck-station＂ network characteristics. A steering for improving the design of heating system and increasing the energy and capital saving of corporations is presented.
