DESIGNING AND SELECTION OF RELIABILITY BASED SAMPLING PLANS

Reliability of engineering system is very much essential in production industries. However accurate Reliability of a system or device is tedious if the number of components or items is large. But the decision has to be made whether to accept or reject a batch of items based on the reliability of the components and hence Reliability-based Sampling Plans indexed by operating reliability rate at the deflection point (RSP-RR) are developed using Exponentiated Log-logistic model. Tables and illustration are also provided for easy selection of the plan. The minimum sample size required for testing the sample units can be obtained using RSP-RR sampling plans.
