Sampling Plan Development in Support of DLA's Quality Assurance LaboratoryTesting Program

摘要

The Defense Logistics Agency's Logistics Management Division (DLA-QL) initiatedactions to improve DLA's Quality Assurance Program by establishing a program of laboratory testing. However, to effectively implement the program, statistically sound sampling plans needed to be developed. Such plans would be used by the Agency in determining appropriate sampling requirements and confidence levels of estimating material conformance levels. DLA-QL requested analytical support from DLA's Operations Research and Economic Analysis Management Support Office (DORO) in developing the required sampling plans as well as a forecasting tool which would be used in predicting the change in conformance levels over time. This report describes the methodology DORO used in developing the sampling plans and forecasting tool. An analysis of the prototype sampling plans and forecasting tool is also provided.
