FUZZY MODIFIED CHAIN SAMPLING PLAN FOR VERY EXPENSIVE PRODUCTS
K. Rebbeca Jebaseeli Edna and V. Jemmy Joyce
In quality control, when the inspection is done for destructive or very expensive products, sampling plans with small sample sizes are normally selected. In this paper the acceptance modified chain sampling plan is developed, when the fraction defective (p) is a fuzzy number. It is found that the operating characteristic (oc) curves of the plan is a band having upper and lower bounds when the proportion of defective is s fuzzy number. The operating characteristic curve of the plan is derived using fuzzy probability.
