TRL2604 EXAMINATIONS PREPARATION, ASSESSMENTS AND REVISION 2025 List and describe the main causes of demand variability within a firm. Main Causes of Demand Variability Within a Firm (choose any 5) Demand variability refers to fluctuations in customer demand over time, which can significantly disrupt supply chain operations. While some variability is externally driven, many fluctuations originate internally due to firm-specific practices, policies, and misalignments across functional areas. Internal demand variability can result in poor forecast accuracy, stock imbalances, lost sales, and increased operational costs (Bowersox, Closs & Cooper, 2002). Identifying and managing these internal sources is essential for ensuring supply chain stability and improving responsiveness. Pipeline transport is a specialized mode of transportation primarily used for the movement of liquids and gases such as crude oil, natural gas, and petroleum products. It plays a critical role in energy logistics and has unique operational characteristics that set it apart from other transport modes (Bowersox, Closs & Cooper, 2002).
