Abstract

In order to improve operational efficiency, this study assesses the impact of batch preparation time in the manufacturing and distribution of ready-mix concrete (RMC) over several construction sites. By means of Arena software, the study intends to find delays, inefficiencies, bottlenecks, and variations in the RMC preparation and delivery process by juxtaposing empirical data with simulated results. Based on thorough data collected over a 30-day period, simulations indicate an average delivery time of 4.78 hours, while empirical data reveals an average of 8.30 hours, so producing a 42% discrepancy. This notable difference shows that present site operations are less effective than the ideal simulation, hence stressing the need for improvements in particular fields. Using a root cause analysis, one has been able to identify elements causing delays, including inefficiencies in batch preparation or delivery systems, which influence general performance. Based on the results, the paper presents a framework meant to improve the efficiency of concrete delivery systems, reducing delays and optimizing operations. The suggestions seek to improve the operational flow of the ready-mix concrete plant, clear obstacles, and offer a more accurate portrayal of actual conditions in replicated models. This study is important since it improves RMC delivery methods, increases the efficiency of building site management, and builds a scalable framework relevant to many different worldwide sectors.
