Construction of Chain Sampling Plan - 2 Indexed through Producer's Nano Quality Level and Consumer's Nano Quality Level

摘要

Motorola (1980) introduced the concept of six sigma as a quality philosophy and a management strategy, which when adopted in a system of organization will reduce wastages, increase the profit to the management and enhance the satisfaction of the customer. If this concept of Six Sigma is adopted in an organization it can results in 3.4 or less number of defects per million opportunities in the long run. In recent days in developed and developing countries more and more organization started working beyond Six Sigma level and thereby the performance level increases with number of defectives reduced to near zero level. Radhakrishnan and Sivakumaran (2008), Radhakrishnan and Balamurugan (2011) introduced Six Sigma quality levels in the construction of sampling plans and control charts. Radhakrishnan (2009) constructed six sigma based sampling plans using Intervened Random effect Poisson distribution and weighted Poisson distribution as the base line distribution. Radhakrishnan and Vinotha (2011) provided a procedure for the construction of sampling plans using Nano Quality Levels. In this paper a new procedure for the construction of Chain Sampling Plan of the Type ChSP-2 indexed through producer's Nano quality level (PNQL) and consumer's Nano quality level (CNQL) is introduced and suitable tables are provided for the easy selection of the plan.
