Worked Example

Verified calculation

Given:

  • Average Demand Rate = 100
  • Demand Standard Deviation = 15
  • Average Lead Time = 2.5
  • Lead Time Standard Deviation = 0.4

Expected Result:

  • Reorder Point Sensitivity = 0.21931712199461

Engineering Interpretation:

Under the given input conditions, the calculated result is: Reorder Point Sensitivity = 0.21931712199461 dimensionless.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

reorder point sensitivity = sqrt(pow(demand standard deviation, 2) * pow(average lead time, 2) + pow(average demand rate, 2) * pow(lead time standard deviation, 2)) / (average demand rate * average lead time)

Frequently Asked Questions

What does this calculator calculate?

The Operations-Optimal Inventory Reorder Point Sensitivity Validator Calculator estimates Reorder Point Sensitivity based on the input parameters you provide

Why is average demand rate important in this calculation?

average demand rate is inversely proportional to reorder point sensitivity. When you enter average demand rate in units/week, the calculator uses it in the engineering formula to compute the output

How should I interpret the result reorder point sensitivity?

The calculator outputs reorder point sensitivity in dimensionless. The result is computed directly from the input values using the defined engineering formula

What units should I use for the inputs?

Enter each value in the units shown next to the input field: Average Demand Rate (units/week), Demand Standard Deviation (units/week), Average Lead Time (weeks), Lead Time Standard Deviation (weeks). Make sure all inputs use the specified units for consistent results

What assumptions does this calculator use?

This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
