Abstract: The study presents an integrated approach that combines ant colony optimisation (AntCO) and dynamic Min-Max normalisation (DMMN), namely the DMMN-AntCO, to address the assembly line balancing problem (ALBP) in the textile industry. The primary objective is to develop a practical approach for decision-making support by minimising workstation processing time deviation from takt time (TT) and reducing operational and setup costs. AntCO generates solutions iteratively using pheromone trails, while DMMN dynamically updates objective function values, allowing unbiased solution comparisons. Experimental outcomes show that the DMMN-AntCO significantly improves workload balance through the smooth index, decreasing from 8.72 to 6.01, and lowers production costs by over 360 USD compared to traditional methods. This study has provided a robust algorithm to optimise production line balancing, reduce costs, and enhance resource utilisation. The results confirm the effectiveness of the DMMN-AntCO method, thereby strengthening the fast response and competitive advantage of companies in the textile industry.
