简介:市政的经济问题具有一个复杂性质。当解决这些问题时,为持续开发的存在要求让我们使用各种各样的标准。例如,这些能包括经济、金融、社会、环境的标准。有效地处理他们,多标准分析应该被使用。关于热生产和交货系统的决定属于如此的多学科的问题。他们通常用古典数字方法论在过去被解决考虑了仅仅各种各样的选择的技术、经济的优点。由相反使用多标准工具,获得更现实主义的结果并且做更有效的决定是可能的。当适用于选择区域加热时,分析层次进程(AHP)似乎是一种好选择充满在它实际上被练习的决策和传统的方法之间的存在差距(DH)系统。这篇论文论述如此的应用。我们的申请是为位于波兰的一个中等大小的城市为一个DH系统选择最好的热能来源。我们的结果关于最好的热能来源导致了一个有趣的结论。我们的结果建议那加强努力使使用普遍更有效,但是财政上更昂贵,精力来源是最好。
