Decision Support System for Safety Stock and Safety Time Buffers in Multi-Item Single-Stage Industrial Supply Chains

Safety stock and safety time are two well-known buffering solutions of material requirements planning (MRP) processes to mitigate against supply demand uncertainty. While the significance proper inventory in managing change has been extensively researched, chain management research on period gotten less attention. Earlier operations quantitative studies, particular, have often evaluated utilization such buffers separately, rather than combined. Considering dynamic demands stochastic timescales, authors present decision support system (DSS) that handle efforts integrate appropriate judgments at level multi-item single-stage multi -supplier industrial chains. The DSS concept is formulated as a mixed bi-objective approach optimizes upstream storage costs -service levels same time, presenting decision-makers with alternative not dominated feasible solutions.
