AUTOMATION OF MEASUREMENT UNCERTAINTY ASSESSMENT BASED ON CMS MAPLE

Abstract

The problem of studying of the uncertainty theory principles and understanding the relationship between the concepts of uncertainty and error and practical application skills of the determining uncertainty method in the international harmonization pursuit and unification of measurement results evaluation were analyzed.The estimating uncertainty results by standard methods can be sublimated into tabular form shown as uncertainty budget. To calculate the indicators that make up the uncertainty budget it is necessary to make a model equation of the studying process, to obtain numerical values for standard uncertainties of types A and B, sensitivity coefficients, total standard uncertainty and extended uncertainty. These calculations require specialists in technical specialties, with a high level of mathematical training and a lot of effort and time to solve practical problems for uncertainty assessment when solving a specific engineering problem. Therefore, it is advisable to use computer mathematics systems (CMS) to calculate the measurement uncertainty budget.Skills possession in working with CMS Maple allows you to algorithmize the estimating measurement uncertainty process. The authors have developed a training program called UC (Uncertainty), which makes it possible to obtain results for budgeting uncertainty in the presence of a model equation of the process and measurement results.Thus, the using CMS Maple expediency and possibility to solve the problems of applied metrology to assess the measurement results uncertainty are substantiated.
