Abstract
This paper presents a simulation-driven digital twin framework for improving smart mobile factory operations for large-scale linear infrastructure construction projects like rail, road etc. The framework integrates pre-deployment and post-deployment phases of Smart Mobile Factory. A Simulation model was built for the pre deployment phase using requirements from the industrial partner, and simulation experiments were conducted to identify bottlenecks and assess the effects of input parameter changes on output. The study compares various configurations of assembly lines, drying times, drying and curing capacities, number of shifts and forklift numbers on throughput and forklift transport distance. The results highlight that increasing drying capacity, parallel assembly lines and improved drying times significantly improve throughput and reduce forklift transportation distance in some scenarios. The best performing configurations were selected, and in the future model will be further developed to integrate real-time data with simulations to address the post deployment phase needs.
