Variable approaches to assessing manufacturability when producing work on construction systems

Introduction. At present, in scientific research, manufacturability of various types: manufacturability of building structures, manufacturability of design solutions, manufacturability of work production and manufacturability of operation of buildings and structures — are determined by various quantitative and qualitative indicators. These indicators form a set of evaluation criteria that allows assessing the level of manufacturability of building systems at various stages. Approaches to assessing manufacturability can vary depending on the initial indicators of manufacturability and the goals of the final result.Materials and methods. The paper is based on the study of variable approaches to assessing manufacturability in the construction of building systems, based on the application of factor models of deterministic analysis. The following key factor models are considered: additive, multiplicative, multiple and mixed (combined). Variations of the resulting indicator — the indicator of manufacturability, based on these models when considering factor features in absolute and relative values are established and analyzed.Results. The completed systematization of variable approaches to technological assessment can serve as a basis for modelling the level of technological effectiveness of construction systems at various stages of the life cycle depending on the factorial characteristics of the processes, as well as as a basis for the formation of a methodological base for a comprehensive assessment of technological effectiveness in the production of work on the installation of construction systems.Conclusions. In the considered variable approaches, in most cases, the calculations of the indicators of manufacturability showed that the considered factor characteristics in the production of the device of building systems provide a mutual influence on the basis for calculating the resulting indicator. Within the framework of approaches based on the use of deterministic factor analysis in assessing manufacturability, the next stage is the study and analysis of the change in the indicator of manufacturability in the production of works on the device of building systems, as a result indicator.
