Simulation Charts

Tether provides visual charts to help you understand simulation results, identify inventory issues, and make informed decisions.

​
Chart Types

​
Inventory Forecast Chart

The primary visualization showing projected inventory over time:
ElementDescription
Blue LineCurrent inventory projection
Green LineProjection with recommended orders
Red ZoneStockout periods
Yellow ZoneLow inventory (below safety stock)
Horizontal LinesSafety stock and overstock thresholds

​
Order Flow Diagram

Visualizes replenishment orders between suppliers and warehouses:
ElementDescription
NodesSuppliers and warehouses
ArrowsOrder flow direction
LabelsOrder quantities and dates

​
Understanding the Timeline

The x-axis shows time from today forward: 
Today -----> Future
  |           |
Start       End of
Date        Simulation

​
Understanding Inventory Levels

The y-axis shows quantity: 
Overstock ─────── Too much inventory
Target ─────────── Ideal level
Safety Stock ───── Minimum acceptable
Zero ──────────── Stockout

​
Key Points to Identify

Declining LineInventory being consumed
Sudden DropLarge order fulfilled
Sudden RiseReplenishment received
Flat at ZeroStockout period
Line Crossing Safety StockLow inventory alert

Chart Types in Detail

​
Current Projection Chart

Shows what happens without any new orders: Use to understand:
  • When stockouts will occur
  • How quickly inventory depletes
  • Impact of current demand
Shows what happens with recommended orders: Use to understand:
  • Impact of recommendations
  • Whether recommendations solve issues
  • Timing of improvement

Using Charts for Decisions

​
Identifying Issues

Crosses safety stockReview recommendations
Reaches zeroOrder immediately
Above overstockReduce planned orders
Erratic patternReview forecast accuracy

​
Validating Recommendations

Before accepting recommendations:
  1. View the “with recommendations” chart
  2. Verify issues are resolved
  3. Check timing makes sense
  4. Confirm no new issues created

​
Communicating Status

Use charts to communicate:
  • Share with stakeholders
  • Include in reports
  • Present in planning meetings

​
Best Practices

Regularly review charts for:
  • High-value products
  • Long lead time items
  • Fast-moving SKUs
Use charts to compare:
  • Current vs. recommended
  • Different what-if scenarios
  • Historical accuracy
Charts communicate better than numbers:
  • Export for presentations
  • Include in status updates
  • Use for alignment
Don’t rely only on charts:
  • Configure inventory alerts
  • Get notified of issues
  • Review charts for details

​
Troubleshooting

​
Chart Not Loading

Possible causes:
  • Simulation not complete
  • No data for selection
  • Browser issue
Solutions:
  1. Wait for simulation to complete
  2. Verify SKU/warehouse has data
  3. Refresh the page

​
Unexpected Pattern

Possible causes:
  • Data quality issues
  • Missing orders
  • Configuration problems
Solutions:
  1. Review underlying data
  2. Check open orders
  3. Verify settings
