Use of probability characteristics of control results

Conclusions

• 1. The use of different probability characteristics of control results in actual problems depends on whether the consumer or the manufacturer of a product is to utilize the results of their solution.

• 2. The greatest interest of the product manufacturers is in the characteristics that enable them to evaluate the improperly controlled fraction in the total volume of production, as these characteristics particularly help them to solve problems of optimizing the product control that is intimately connected with its manufacturing technology as well as to solve problems of economic nature associated with expenditure on compensation of defects, process stock, etc.

• 3. The consumers of large batches of products (wholesale dealers) are interested in the probability characteristics of control results that relate only to the total volume of products that have been found suitable after the control test (customer's risk) as they do not deal with other products (that have been rejected in the control test). These characteristics are unequivocally connected with the previous ones and must be communicated by the manufacturers to the wholesale dealers or must be asked by the customers from the manufacturers.

• 4. The consumers of individual specimens and small batches of products are interested in the limiting probability characteristics of control results particularly the maximum hypothetical probability of undiscovered defects in products as only this parameter guarantees to the consumer the necessary quality control of a concrete product specimen.
