Qualimetric model for assessing the impact of the level of development of corporate information systems on the quality of aerospace instrumentation

Abstract

In the context of the digital transformation of the economy, the effective development of corporate information systems of research and production holdings of aerospace instrumentation is becoming one of the decisive factors in ensuring the high quality of domestic avionics. This article is devoted to the analysis of the influence factor of digitalization and informatization processes in scienceintensive industries of modern aerospace instrumentation, as well as the definition of a qualimetric model for assessing its impact on the quality of domestic avionics products in the current economic and technological conditions. The influence of the level of development of corporate information systems of aerospace instrumentation enterprises on the quality of domestic avionics products is assessed in the article on the basis of the corresponding hierarchy of quality indicators. The proposed model of the influence of the level of development of corporate information systems on the quality of aerospace instrumentation products assumes the choice of the form of the integral criterion depending on the external requirements for the efficiency of the assessment, the sensitivity of the system of quality indicators.

Methodology for choosing the best design solution in construction

“…In the process of architectural design and construction, specialists evaluate design solutions at all stages of its development: master plan, space-planning and constructive solution, floor plans, facades, interiors, load-bearing and enclosing materials etc. [5]. The purpose of this evaluation is to select the best possible option.…”

“…Each assessment is carried out according to specific criteria and requirements. Therefore, before comparing project evaluation methods with each other, it is necessary to determine the requirements that these methods must meet [6].We analyzed the requirements for the assessment method for selecting the best possible option [5].Unlike well-known evaluation methods, the qualimetric method allows to quantify the quality of the design solution [9,10].…”

“…Major principles of the qualimetric method are: priority of the consumer while choosing project quality indicators; presence of a basic standard or options for comparing the design solutions; development of a hierarchical structure of project quality indicators: single indicators of the simplest properties, generalized quality indicators, integral indicator; reduction of different-sized indicators of properties to one dimension or to dimensionless units of measurement based on qualimetric scales;using of weights coefficients for each indicator to determine the integral one [5].…”

“…[7,8].By scale -small projects (construction or reconstruction of small and simple individual objects), medium, large, giant projects can be grouped. By the duration -projects with a short, medium, and long construction period [5].…”

“…The stage 5thincludesbuilding a graphical model of quality properties hierarchy. When constructing a "property tree", first the quality is characterized by generalized properties, then the generalized properties are divided into smaller ones (simple, quasi-simple) [5].…”
