Predicting production time of free-form concrete panels using 3D plastering technology

摘要

For the practical application of free-form concrete panel (FCP) production using 3D plastering technology, the in-plant production must be performed to meet the tight schedule of FCP installation on site. To this end, critical activities and their working times that affect FCP production time must be accurately analyzed. The objective of this paper is to develop the algorithms for predicting production time of FCPs using 3D plastering technology. This study was performed by analyzing the FCP production process and core activities such as free-form shaping and 3D plastering works, and then using the results to develop a generalized FCP production time predicting algorithm. Through the case application of the algorithm, the relationship between the production time and the number of machines required was derived by simulation. The results of this study help to solve the time and cost conflicts that may occur in the production of FCPs. The proposed algorithm should be developed as a compu-terized program for simulating the number of machines required according to the FCP production schedule for practical use.
