A comprehensive supply chain decision engine replaces traditional forecasts with probabilistic planning and economics-driven optimization, enabling price trade-offs, dynamic inventory and replenishment, procurement decisions, and last-mile routing to be made under uncertainty with auditable, automated bets. It is designed for operations managers, supply chain analysts, pricing and procurement teams, students, and educators across manufacturing, retail, and e-commerce who seek faster, more resilient decisions, reduced capital misallocation from forecast-centric planning, scenario analysis, and KPI-driven governance that scales across regions and catalogs.
