Comparison of Certain Types of Continuous Sampling Plans (CSPs) and its Operating Procedures

K. K. Suresh | V. Nirmala

Abstract: Sampling is widely used in manufacturing industries and government agencies for controlling the quality of shipments of components, supplies, raw materials and final products. Continuous sampling plans are useful when the formation of lots for sampling inspection is impracticable or artificial. The application of continuous sampling plan is continuous flow of units from which the production process and units are offered for inspection item by item in the order of their production. Dodge (1943) has introduced the concept of continuous sampling plan and provides mathematical rationale and rules of operation for continuous sampling plan of type CSP-1. In this paper provides various kinds of continuous sampling plans and its operating procedures are compared. Continuous sampling plan is simplest and most commonly used single level Continuous sampling plan. The other continuous sampling plans namely CSP-2, CSP-3, CSP-4, CSP-5, two level CSP, tightened two level CSP, multiple level CSP, tightened multiple level CSP, CSP-F, CSP-T, CSP-T with GERT, three level CSP, modified tightened three level CSP, and CSP-C (Markov chain modal) contain some differences due to the implementation and the theoretical foundation among them.

Keywords: Continuous sampling plan, Mathematical Rationale, Sampling Procedure, Operating procedure, Theoretic foundation
