Exact Multi-attribute Acceptance Single Sampling Plan

Abstract

In this article, we develop an ‘Exact Multi-Attribute Acceptance Single Sampling Plan’ (E-MAASSP) of the desired error probabilities (α*, β*) without assuming independence of the attributes. In case of two attributes, the design parameters of E-MAASSP are obtained for given input parameters. A control chart based on E-MAASSP is proposed and a simulation study is carried out. When a lot (or a process) is not conforming to the quality, a procedure is proposed to identify the responsible attributes.

Key Words:

• Control chart
• Acceptance Sampling Plan
• Multinomial distribution
• Error probabilities
• MP test
