Abstract

Modular construction is recognized as a promising solution to the pressing housing demands of densely populated cities. However, temporary storage of modules in urban environments and the risk of damage during transportation present significant supply chain challenges. Some governments have begun investing in integrated operation centers (IOCs) to provide module storage and repair services. However, there lacks an effective planning framework for IOC establishment and operation. This paper formulates a bi-level programming model that comprehensively considers land availability, budget limitation, and government–contractor interactions. A particle swarm optimization based algorithm is developed and validated through a Hong Kong case study. Computational experiments provide governments with valuable managerial implications regarding IOC investment budget, number and locations of IOCs, and services provided by IOCs. Overall, the proposed models, solutions, and recommendations are expected to facilitate the just-in-time cross-border delivery of precast modules in densely populated cities.

用于储存和维修进口预制模块的综合运营中心
模块化建筑被认为是解决人口稠密城市迫切住房需求的一种可行方案。然而,模块在城市环境中的临时存储和运输过程中的损坏风险给供应链带来了巨大挑战。一些政府已开始投资综合运营中心(IOCs),以提供模块存储和维修服务。然而,目前还缺乏一个有效的规划框架来建立和运营综合运营中心。本文提出了一个双层规划模型,综合考虑了土地可用性、预算限制以及政府与承包商之间的互动。本文开发了一种基于粒子群优化的算法,并通过香港的案例研究进行了验证。计算实验为政府提供了有关增支经营成本投资预算、增支经营成本的数量和地点以及增支经营成本提供的服务等宝贵的管理启示。总之,所提出的模型、解决方案和建议有望促进人口稠密城市预制模块的及时跨境交付。

期刊介绍: Automation in Construction is an international journal that focuses on publishing original research papers related to the use of Information Technologies in various aspects of the construction industry. The journal covers topics such as design, engineering, construction technologies, and the maintenance and management of constructed facilities. The scope of Automation in Construction is extensive and covers all stages of the construction life cycle. This includes initial planning and design, construction of the facility, operation and maintenance, as well as the eventual dismantling and recycling of buildings and engineering structures.
