Allocation
Allocation identifies the amount of parameter variation that will improve a response's variation to a desired level. (This is often referred to as statistical tolerancing or requirements flowdown.) With allocation you can specify a desired value for response standard deviation or response PNC and the algorithm will compute a vector of parameter standard deviations that will meet your objective. Driver values are used to help guide the parameter standard deviations in sensible directions.
Features:
- Identify tolerances that are too tight or too loose
- Quantify risk of not meeting requirements
- Easy-to-use and learn interface
- Unlimited number of factors*
- Truly statistical tolerancing
- Define parameter variability budgets and tolerances that strike the right balance between quality & cost
- Advanced calculations for numerical derivatives
- 2nd-order analysis
- User-selectable allocation drivers
- Nonlinearity test and warning
*Constrained only by worksheet size/memory limits in MS Excel™
