对大型集中供热系统而言，设计过程包括“管-站”布局设计和管网系统设计。根据最优化理论，提出了集中供热系统的两级优化设计模型，即第一级的“管-站”布局优化和第二级的管网系统多目标优化设计模型。由于“管-站”布局优化模型属NP—hard问题（不确定问题），为寻求有效解法，对“管-站”布局优化模型提出两步分级法求解，即优化过程分两步进行，第一步为分区优化，第二步为选址优化。运用本文所述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。
In terms of large central heating system, the process includes the design of the ＂duct-station＂ layout and pipe network system. According to optimization theory, a suitable two-stage optimization layout method is raised which is made up of the ＂duct-station＂ optimization layout model （the first stage）and the multi-objective optimization model （the second stage）. Optimization model of the ＂duct-station＂ layout belongs to NP-hard problem （Uncertainty problem）. In order to find out an effective solution, we propose two-step classification method of ＂duct-station＂ layout optimization model, which is two-step optimization process. The first step is the partition optimization and the second step is location optimization. Using this method, a central heating system is transformed in ZhenXing district Liaohe oilfield, and also optimization design is accomplished, which achieves good results.
