The EOQ & EPQ Inventory Cost Optimizer is a professional operations research and financial modeling tool designed for supply chain managers, procurement directors, and production planners. Maintaining the right inventory balance is a constant challenge: ordering or producing too frequently spikes operational setup costs, while holding massive stockpiles locks up valuable working capital. This dual-engine calculator utilizes mathematical modeling to locate the absolute cost minimum.
The template provides two isolated mathematical engines alongside a comparative testing module, serving as a comprehensive tactical framework for sourcing and production lot-sizing.
Key Features and Capabilities:
1. Economic Order Quantity (EOQ) Engine: Computes the optimal vendor order volumes based on annual demand, ordering fixed expenses, item purchase prices, and customized inventory carrying holding rates.
2. Economic Production Quantity (EPQ) Engine: Built specifically for in-house manufacturing, this simulator calculates ideal manufacturing batch sizes by factoring in technical production run-rates against baseline demand drop-offs.
3. Sensitivity Scenario Manager: The specialized "Scenario Analysis" module stress-tests calculations against volatile market developments, modeling $+/-20%$ demand shocks, spiking holding percentages, process cost variances, and production bottleneck thresholds.
4. Clear Data Architecture: Formulated completely with open, native Excel formulas without any password locks, hidden logic, or macro dependencies, ensuring transparent compliance with corporate auditing standards.
