平移置换搬迁系统设计与实现

Design and Implementation of the Parallel Translation and Relocation System

摘要: 我国的城镇化进程正在进入存量更新和提质增效的关键阶段，其中在特大城市和大城市的老城平房街区则因为“共生院”问题很难在传统更新模式下实现院落高效开发。针对某一老街区的平移置换需求，本研究构建了系统性的规划方案：首先结合面积采光以及修缮约束条件来整合居民的居住需求和开发商的成本条件，采用混沌遗传的方法确定搬迁补偿方案；其次以“空出完整院落最多、毗邻度最高、搬迁户数最少”为目标来进一步优化搬迁决策，同步核算成本以及开发商收益，来确保成本满足开发商控制需求。最后无保底成本约束的情况下，以十年期的开发商性价比为核心，计算性价比变化。最终为开发商提供相应智能软件，通过输入参数来自动计算搬迁方案以及相应效益，来适配全国的老旧街区平移置换。研究实现了居民本地居住诉求和开发商效益的平衡，为老城区更新提供方案支撑。

Abstract: China’s urbanization process is entering a critical stage of stock renewal and quality-efficiency improvement. Among them, the old urban bungalow blocks in megacities and large cities face great difficulties in achieving efficient courtyard development under the traditional renewal model due to the “cohabitation courtyard” issue. To address the demand for translation and replacement of a specific old block, this study constructs a systematic planning scheme: Firstly, it integrates the residential needs of residents and the cost conditions of developers by considering constraints such as area, lighting, and renovation requirements, and adopts the chaotic genetic algorithm to determine the relocation compensation plan. Secondly, it further optimizes the relocation decision with the goals of “maximizing the number of complete vacated courtyards, maximizing adjacency, and minimizing the number of relocated households”, and synchronously calculates costs and developers’ benefits to ensure that the costs meet the developers’ control requirements. Finally, without the constraint of a minimum guaranteed cost, it calculates the changes in cost-performance ratio focusing on the developers’ ten-year cost-performance ratio. Ultimately, it provides corresponding intelligent software for developers, which can automatically calculate relocation plans and corresponding benefits by inputting parameters, so as to adapt to the translation and replacement of old neighborhoods nationwide. This study achieves a balance between residents’ local living demands and developers’ benefits, and provides scheme support for the renewal of old urban areas.
