多属性决策及灰色关联投影法在供暖方案选择中的应用
Application of multiple attribute decision-making and grey relation projection to heating scheme selection
摘要：
针对既有社区供暖系统存在的问题，基于区域资源条件分析结果，提出了3个改造方案：燃气锅炉、海水源热泵蓄热与燃气锅炉调峰、海水源热泵与空气源热泵蓄热调峰。通过组合赋权法确定节能、经济、环保3个指标权重，采用多属性决策及灰色关联投影的方法，对3个方案进行对比分析,并得出了优选方案。结果表明，天然气与可再生能源结合供热，能够实现多能互补、互惠互利，为我国既有社区供热方案改造提供参考。
Abstract：
For the heating system problems in an existed community, based on the regional resources condition analysis, puts forward three plans, including the gas boiler, the seawater-source heat pump and gas peak-shaving boiler, the seawater-source heat pump and air-source heat pump peak-shaving. Determines the weights of the energy saving, economy and environmental protection factors by the weighting approach combination. Adopts the multiple attribute decision-making method and grey relation projection method to find out the prior plan. The result shows that the combination of natural gas and renewable energy in heating system can achieve the goal of multi-energy complementary and mutual benefit, which provides the references for the existed community heating scheme reformation.
