CHAPTER OVERVIEW AND LEARNING OBJECTIVES

This chapter summarizes several useful acceptance-sampling techniques, including variables-sampling plans, which can be used as alternatives to attribute plans when measurement data are available. We also briefly discuss chain sampling, continuous sampling, and skip-lot sampling.

After careful study of this chapter, you should be able to do the following:

  1. Understand the difference between attributes- and variables-sampling plans
  2. Understand the advantages and disadvantages of variables sampling
  3. Understand the two major types of variables-sampling plans
  4. Know how to design a variables-sampling plan with a specified OC
  5. Understand the structure and use of MIL STD 414 and ...
