Data Table Structures and Columns

1. Historical Sales Data (Sheet 2)

2. Product Inventory & Replenishment Tracker (Sheet 3)

3. Demand Forecasting Model (Sheet 5)

This advanced sheet applies time-series analysis techniques such as Moving Average, Exponential Smoothing, and Linear Trend Regression to forecast sales for upcoming periods (e.g., weekly or monthly).

Required Formulas

• Suggested Order Qty: =MAX(0, Reorder Point - Current Stock Level), but adjusted to meet MOQ if necessary.
• Reorder Point: =Safety Stock + (AVERAGE(Daily Demand) × Lead Time)
• Moving Average: =AVERAGE(OFFSET(Sales, -3, 0, 3))
• Exponential Smoothing: =0.3 * Actual + 0.7 * Previous Forecast
• Final Forecast: =Weight1*MA + Weight2*ES + Weight3*Trend, with weights summing to 1.
• Safety Stock: Calculated using standard deviation and service level: =NORM.S.INV(Service Level) * STDEV(Daily Demand) * SQRT(Lead Time)

Conditional Formatting Rules

• Stock Level: Red if below safety stock; yellow if within 10% of safety stock; green otherwise.
• Suggested Order Qty: Highlight in orange if above MOQ, red if less than MOQ and non-zero.
• Demand Forecast: Use gradient color scales to visualize high/low forecast trends across months.
• Reorder Date: Flag entries older than 30 days in red for urgency alerts.
