摘要： Current production methods for the building of precast concrete elements are gradually becoming insufficient to meet industry demands. Most precast factories incorporate fixed molding production lines to produce building structural elements such as beams, trabeculae and pillars. Improvement of current production has reached its limits. The objective of this study is to perform process reengineering so as to create more efficient precast processes. The results of the literature review and advice from 16 experts suggest that the current process used to produce a precast element, which is comprised of 16 steps in a single module, should be redesigned to include 13 steps in 3 modules. Using historical data as input, the Arena software, Version 13, is adopted to simulate both the traditional and proposed methods, and then compare the results for practicability. An overall savings of production time of 24% can be reached by changing the current/traditional method to the flow-shop type production method. •Precast production was reengineered based on flow-shop method.•Traditional precast production line has been modified to 3 flow-shop modules.•The proposed model can save almost 25% of production time. 出版者： Elsevier B.V 出版日期： 2016-08 出處： Automation in construction, 2016-08, Vol.68, p.249-258 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2016 Elsevier B.V. 識別號： ISSN: 0926-5805 識別號： DOI: 10.1016/j.autcon.2016.05.015
