Within manufacturing, measurements are used to make decisions related to product
verification and process control. The selection of production machines and
instruments involves a trade-off to achieve the required accuracy while
minimizing cost. Similarly, deciding on the level of confidence at which
products are rejected is a trade-off between the cost of rejecting acceptable
parts and the cost of passing substandard products to the customer. These
trade-offs can only be optimized if the uncertainties are fully understood.
Currently multiple methodologies are used to understand uncertainties and
variation within manufacturing, such as measurement systems analysis (MSA),
statistical process control (SPC), and uncertainty evaluation. The industry
lacks a unified approach that provides a complete understanding of uncertainty.
This means that optimal decisions cannot be made to maximize the profitability
of production systems.
NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key
issues in emerging, but still unsettled, technologies of interest to the
mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate
discussion and work in the hope of promoting and speeding resolution of
identified issues. SAE EDGE™ Research Reports are not intended to resolve the
issues they identify or close any topic to further scrutiny.
