Abstract

This paper aims to comprehensively analyze the supply chain activities of an Internet Service Provider company in Thailand, focusing on sustainability. The company utilizes the SCOR model and IDEF0 methodology to analyze the supply chain and offer rental equipment services. The major issues identified include inventory management, insufficient data in demand planning, supply chain planning, renewal contact planning, the role of suppliers, and last-minute changes during the installation process. To address these challenges, the paper suggests improvements such as optimizing equipment flow, improving communication with teams, implementing demand forecasting models, considering alternative suppliers, and clarifying technical requirements with customers. By implementing these recommendations, ISPs can enhance the sustainability of their supply chains, reducing environmental impacts, optimizing resource utilization, and meeting customer expectations for sustainable practices. This study highlights the importance of sustainable supply chain practices in the telecommunications industry and offers valuable insights for companies seeking to improve their operations in a more environmentally responsible manner.
