불량율(不良率)의 사전분포(事前分布)를 고려(考慮)한 연속생산형(連續生産型) 샘플링검사(檢査)

Continuous Sampling Plans with Prior Distribution

The concept of AOQL in designing Dodge's continuous sampling plans is modified to include probabilistic consideration reflecting the prior knowledge about the process average fraction defectives, and a new design criterion called AOQL, which eliminates some of the drawbacks of the AOQL criterion is proposed. AOQL, approach provides more economical sampling plans in many cases, and can be used even when only limited amount of prior information is available.
