Abstract

Ballard’s concept of work structuring for production planning in construction can be applied to improve production flow in construction projects formed by repetitive units with extensive customization. Customization can increase the value of repetitive units (apartments in a building, houses in an allotment, or stores in a shopping mall) forming a project, by meeting clients’ specific requirements. However, in traditional construction production systems, it commonly causes delays, stoppages, rework, increased amounts of work in progress, and excessive movement of crews and materials. The problem has been thoroughly documented and various production systems have been designed to address the trade-off between flow and value. We identify five such systems, which were originally developed following exploratory design science principles. In this work, we analyse and compare them using nine metrics to assess their performance in terms of flow and value, and to explore the role of work structuring in customized projects. The systems with the most effective flow are the Fit-Out Company and the Ecosystem Platform systems. The analysis led to the theoretical proposition of a hybrid production system called Product/Process Modularization, which may be applied and tested in the future.

摘要

巴拉德的建筑生产计划工作结构概念可用于改善由具有广泛定制的重复单元形成的建筑项目的生产流程。定制可以通过满足客户的特定要求来增加构成项目的重复单元（建筑物中的公寓、分配中的房屋或购物中心中的商店）的价值。然而，在传统的建筑生产系统中，它通常会导致延误、停工、返工、正在进行的工作量增加以及人员和材料的过度移动。该问题已被彻底记录，并且已经设计了各种生产系统来解决流量和价值之间的权衡。我们确定了五个这样的系统，它们最初是根据探索性设计科学原则开发的。在这项工作中，我们使用九个指标对它们进行分析和比较，以评估它们在流程和价值方面的表现，并探索工作结构在定制项目中的作用。具有最有效流量的系统是装修公司和生态系统平台系统。分析得出了一个名为“产品/流程模块化”的混合生产系统的理论命题，该系统可能会在未来得到应用和测试。
