A generalized model of a building system: a critical analysis

Introduction.

The established modeling paradigm of a building system as a branch of economy considers individual building processes or groups of interconnected processes, ignoring any previous or subsequent processes or those processes and transactors that are indirectly related to the building system. A critical analysis of a generalized model of the construction system has been performed. The subject of the study is a detailed examination of the construction process. This project takes account of the influence of related, earlier and upcoming stages of the construction process. The research is focused on reducing the number of cost overruns, unmet deadlines in terms of facilities and particular processes, as well as improving the overall organizational and technological reliability of the entire construction system. The purpose of the study is to propose a more progressive and comprehensive vision of the construction system as a branch of economy, the system that takes account of all stakeholders.

Materials and methods.

The review of studies on this topic was made; current restrictions were identified. The author has found that the most widely spread approach focuses on individual processes or a group of related processes.

Results.

The author has found that an objective assessment of the influence of previous processes on subsequent ones, an evaluation of the reliability of the whole system, and a correct identification of risks at early stages are unavailable. Further in-depth research using methods of mathematical statistics is needed to provide an objective solution to global engineering problems in the construction industry, which will allow to reduce deviations in the cost and duration of the implementation of facilities and individual processes.

Conclusions.

To date, a sufficiently comprehensive approach to the analysis of risks/failures in construction systems as a whole has not been presented. The need for a deeper vision of a complex building model that identifies risk factors and chain links has been identified. The use of techniques tested by the author is proposed as a mathematical tool.
