The acceptance sampling plan add-in provides a point-and-click interface for generating / creating, evaluating and comparing sampling plans.
Specifically, one can create sampling plans by lot acceptance sampling by attributes and variables acceptance sampling. Attribute sampling plans supported include:
- Single
- Zero ( C = 0, Squegila Plans )
Variable sampling plans supported include:
- Sampling by Variables for proportion nonconforming
Key features:
- Generate / Create sampling plans
- Evaluate sampling plans
- Compare up to 5 sampling plans
- Operating Characteristic ( OC ) Curves
- Acceptance Region Plot
- K-Method for variables sampling plans
- One-sided spec limits
- Two-sided spec limits
- Generate variables collection table for analysis with unknown standard deviation
- Validation / Integration test cases
- Performance measures for Average Outgoing Quality (AOQ) and Average Total Inspection (ATI)
- Acceptance region
