Constrained Service Level Optimization (CSLO) is an algorithmic capability that calculates the lowest-cost service level for each SKU while satisfying aggregate service, spend, and capacity limits. The approach replaces static inventory policies with dynamic optimization that accounts for lead-time, cost, and forecast-error variation across segments. Users can run multiple policy scenarios, compare current versus simulated metrics, and apply results directly to active replenishment rules.

Key takeaways

CSLO assigns differentiated service levels to SKUs to meet aggregate targets at minimum cost

Optimization modes include minimize carrying cost, minimize total cost, or maximize service under spend caps

Handles constraints such as budget, space, contractual SLAs, and profit goals

Scenario tools allow side-by-side comparison of current policy versus proposed changes at SKU level

Self-service UI reduces reliance on external consultants for policy configuration and maintenance
