Accuracy Of Measurement

The development of methods for selective measurement control of commercially available products, the quality of which is characterized by a number of parameters, is considered. At the same time, it is necessary to establish reasonable requirements for the accuracy of measurement of parameters, as well as the sample size of controlled products. If the controlled parameters are correlated, the problem of optimizing their number arises.Using the Monte Carlo method (simulation modeling), we investigated the effect of measurement uncertainty and the sample size of controlled products on control reliability indicators. The average risks of the customer and the manufacturer are calculated while monitoring samples of products of various volumes. The calculations were made under the assumption that the quality of each product is characterized by 30 uncorrelated parameters. It is shown that in the considered case there is an almost linear dependence of the mentioned risks on the volume of the controlled sample of products.

The Monte Carlo Method

The article has considered the calculation of the unified glare rating (UGR) based on the luminance spatial-angular distribution (LSAD). The method of local estimations of the Monte Carlo method is proposed as a method for modeling LSAD. On the basis of LSAD, it becomes possible to evaluate the quality of lighting by many criteria, including the generally accepted UGR. UGR allows preliminary assessment of the level of comfort for performing a visual task in a lighting system. A new method of "pixel-by-pixel" calculation of UGR based on LSAD is proposed.

The Monte Carlo Method

The article is a continuation of the software research to perform probabilistic seismic hazard analysis (PSHA) as one of the main stages in engineering seismic surveys. The article provides an overview of modern software for PSHA based on the Monte Carlo method, describes in detail the work of foreign programs OpenQuake Engine and EqHaz. A test calculation of seismic hazard was carried out to compare the functionality of domestic and foreign software.
