The textile industry, a cornerstone of global manufacturing, faces numerous challenges in optimizing supply chain management (SCM), particularly in inventory and warehouse operations. The barriers hindering SCM implementation in the Bangladesh textile sector were identified and ranked using AHP and Delphi methods in this study. Sixteen barriers grouped in the categories of Inventory Control, Quality Control, Transportation, and Raw Material Sourcing were analyzed and validated through the Delphi method and subsequently, through the AHP method, barrier ranking was undertaken in an attempt to measure which barrier was more critical than another. The results portray that among all categories, Inventory Management was the most dominant barrier along with deficiencies in setting optimal inventory levels, forecasting demand, and errors associated with human factors. These findings present a comprehensive methodology for tackling the challenges posed by poor SCM practices, providing relevant information for practitioners in the industry on how to improve profitability, minimize expenses, and strengthen operational agility. This study presents the opportunities that data driven methodology offer to improve SCM operations within the textile sector.
