Price Adjusted Single Sampling with Linear Indifference

Summary: This paper introduces and develops a new concept in statistical sampling, Price Adjusted Single Sampling (PASS) with linear indifference. The basic purpose in developing this inspection technique is to eliminate the process of rejecting lots, a common practice of all currently used sampling procedures. The basis and statistical model for PASS are developed such that a particular plan may be formulated and implemented. The theory is extended to include sampling risks incurred by the producer and consumer. This leads to both an operating curve which describes how a plan may be expected to function and to PASS Tables, which provide sample sizes for plans which encompass a wide variation in consumer and producer risks. Advantages and disadvantages of price-adjusted single sampling are discussed. A major limitation on the application of these plans is a linear indifference assumption.
