Demand uncertainty and inventory disruptions continue to present significant challenges for organizations operating in manufacturing, distribution, and service-oriented sectors. This research develops a quantitative framework for inventory resilience assessment by integrating demand forecasting, variability analysis, and inventory optimization techniques. Historical operational data are analyzed to identify demand patterns and variability characteristics using statistical forecasting models. Inventory planning decisions are evaluated through simulation and optimization methods designed to balance service levels and inventory carrying costs. Enterprise information systems provide structured datasets for monitoring inventory performance and supporting decision-making processes. The study examines the relationship between demand fluctuations, replenishment policies, and operational continuity under varying business conditions. Performance measures including stockout frequency, inventory turnover, service level attainment, and cost efficiency are used to evaluate the effectiveness of the proposed framework. Results demonstrate that resilient inventory planning strategies can enhance organizational adaptability, improve resource utilization, and reduce operational risks associated with uncertain demand environments.
