Abstract Urban regeneration represents an opportunity for sustainable development and smart growth of towns. The European best practices of urban regeneration demonstrate its effectiveness to valorize obsolete existing buildings, through integrated design of energy and structural upgrade. In countries of southern Europe, characterized by medium to high seismic risk, programs of urban regeneration, would make it possible to reduce buildings vulnerability, through seismic upgrade/retrofit interventions, or alternatively, through demolition and reconstruction interventions, when the previous ones do not allow the improvement of seismic performance of building structures in order to ensure adequate levels of safety. The research work sets out a real case for a possible process of urban regeneration, of a residential neighborhood located in the city of Matera, through demolition of existing buildings and then their reconstruction in the same volume size or, eventually, increased in relation to the premiums of volume required by current regulations. The process involves three different categories of stakeholders: residents, public sector and private investor responsible for executing and financing of the entire processing. Each of them with different and contrasting needs. At the end of the process, the new surfaces should be redistributed between residents and private investor. These shares, with the volumetric premium, constitute the unknown variables of the problem and, their possible combinations represent the different possible options of intervention. The problem is solved through the construction of the model based on the objective functions, expressed by utility functions, defined for each stakeholder. The search for the optimum solution, which is able to balance the different utilities, is carried out with Multi-objective linear programming.

支持城市更新决策的模型

摘要 城市更新是城镇可持续发展和智慧增长的契机。欧洲城市更新的最佳实践证明了其通过能源和结构升级的综合设计使陈旧的现有建筑增值的有效性。在具有中高地震风险的南欧国家，城市更新计划将有可能通过抗震升级/改造干预措施或通过拆除和重建干预措施来降低建筑物的脆弱性，而以前的措施则没有允许改善建筑结构的抗震性能，以确保足够的安全水平。研究工作为城市更新的可能过程提供了一个真实案例，位于马泰拉市的一个住宅区，通过拆除现有建筑物，然后以相同的体积大小重建，或者最终根据现行法规要求的体积溢价增加。该过程涉及三类不同的利益相关者：居民、公共部门和私人投资者，负责整个过程的执行和融资。他们每个人都有不同和对比鲜明的需求。在过程结束时，新的表面应在居民和私人投资者之间重新分配。这些份额与体积溢价构成了问题的未知变量，它们的可能组合代表了不同的可能干预选项。该问题通过基于目标函数的构建来解决，目标函数由效用函数表示，为每个利益相关者定义。通过多目标线性规划来寻找能够平衡不同效用的最佳解决方案。
