Development of models for forecasting and classification of a printing quality of a low cost 3D printer
At the present, the actual task is using 3D printers for the manufacture of certain objects with a given level of price / quality ratio. In many cases, it is economically feasible to use a low cost 3D printer. Therefore, it is necessary to have models that predict and classify the printing quality of such printers. The work has involved the development and assembly of a low cost 3D printer. For this purpose, the creation of geometric models of the component parts and the printer itself was carried out, and engineering calculations and optimization of the received designs were performed. It has been developed a printer control system. An experiment was conducted to produce cubes with different printing parameters on such printer. Based on regression analysis, linear and logistic regressions were constructed. Linear regression will allow to assess the quality level of the result depending on the printing parameters, and the logistic regression will allow to classify and predict the probability of manufacturing objects with a given quality level. The influence of each of the print parameters on the quality and result of the classification was analyzed.
Consider the dependence of coefficient of quality equipment from a variety of factors and its influence on the reliability of modern software and hardware systems. In terms of reliability software and hardware systems are serial connection elements. For them, the prediction model of the failure rate in the mode of operation depends on the technical means failure rate, the Software Tool failure rate and coefficient of quality equipment.
The article deals with the semantic structure of the verb and its correlation with quality.
The article presents results of the research of methods of quantitative analysis of conflicts, arising during information technology project realization and evaluation of their use for appraisal according to Capability Maturity Model Integration.
Today there are the real importance in global management of quality for light production`s enterprises. The article describes the way of installation of the composite indicator of enterprise` s operation`s effectiveness in situation of concrete organization, where the way of production activity and specific types of defects are observed. At the end of researches the recommendations of economic results improvements and promoting competitiveness are published. It can be used for all light production`s enterprises for optimization of product quality`s controlling system
This issue reveals problems and contradictions standing from the technical legislation reform in Russia. System of technical reglaments, new to Russia, excludes most, but not all standards from the sphere of public protection provided by the State. As a result, standards provided by the Technical Legislation Law are freewill standards and standards provided by other acts are compulsory. It disrupts the system of standards and increases risks and expenses of producers, customers and the State.

The application of mathematical modeling methods (with subsequent computer sales) to determine the parameters of accuracy geometry bands obtained with the new equipment and process the step deformation bands of hard alloys based on copper
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
