Yu, M; Wang, L; Ruan, W and Zheng, W (2025) Robust optimization for precast component production scheduling considering component transfer. Journal of Construction Engineering and Management, 151(10): 04025156, ISSN 0733-9364
Abstract
Inefficient coordination on component transfer links between production processes, combined with high uncertainty in the production environment, significantly reduces the efficiency of precast component manufacturing. Though uncertainties within the production processes have been largely discussed, the effects of uncertainties in interprocess transfer links have not been considered. This study is the first to develop a robust scheduling model for precast component production that integrates the interplay between production processes and transfer links. A hybrid genetic-simulated annealing optimization algorithm is used to solve the model. Validation through real-world cases reveals that the robust model reduces buffer usage by 25.01% and decreases completion times by 9.49%. Additionally, the proposed parallel sequential transfer scheduling approach can significantly reduce interprocess waiting without adversely affecting completion times. The results indicate substantial improvements in the scheduling robustness. The successful application in practical scenarios highlights the optimization method to improve production efficiency in the precast construction industry.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
