An Approach to Combining Results From Multiple Methods Motivated by the ISO GUM
نویسندگان
چکیده
The problem of determining a consensus value and its uncertainty from the results of multiple methods or laboratories is discussed. Desirable criteria of a solution are presented. A solution motivated by the ISO Guide to the Expression of Uncertainty in Measurement (ISO GUM) is introduced and applied in a detailed worked example. A Bayesian hierarchical model motivated by the proposed solution is presented and compared to the solution.

Proposing a quantitative approach to measure the success of energy management systems in accordance with ISO 50001: 2011 using an analytical hierarchy process (AHP)
ISO 50001: 2011 provides an integrated and systematic framework to plan, implement, operate, certify, and maintain energy management systems (EMSs). Evaluation of organizations in relation to meeting the standard requirements is performed by an auditing qualitative approach. In this research, a quantitative approach has been proposed and implemented to assess organizations and rank them based o...
متن کاملApplication of traceability concepts to analytical quality control may reconcile total error with uncertainty of measurement.
In this issue of CCLM, a contribution from Prof. James West-gard (1) rekindles the debate, started 10 years ago by Dr. Dybkaer (2, 3), who opposed total error and the uncertainty of measurements performed in clinical laboratories. In agreement with the ISO 15189 standard (4), both scientists agree in principle that laboratories should know the uncertainty of their results for assessing whether ...
