Construction of Mixed Sampling Plans Indexed Through Six Sigma Quality Levels with Chain Sampling Plan-(0,1) as Attribute Plan

Six Sigma is a concept, a process, a measurement, a tool, a quality philosophy, a culture and a management strategy for the improvement in the system of an organization, in order to reduce wastages and increase the profit to the management and enhance satisfaction to the customers. Motorola (1980) first adopted the concept of six sigma in their organization and established that it can produce less than 3.4 defects per million opportunities. Focusing on reduction of defects will result in more profit to the producer and enhanced satisfaction for the consumer. The concept of Six Sigma can be applied in the process of quality control in general and Acceptance sampling in particular.

In this paper a procedure for the construction and selection of Mixed Sampling Plan indexed through Six Sigma Quality level having the Chain Sampling Plan-(0,1) Plan [ChSP-(0, 1)]) as attribute plan is presented. The plans are constructed using SSQL-1 and SSQL-2 as indexing parameters. Tables are constructed for easy selection of the plan.
