Formation of a geographically distributed network structure for the production of factory-ready housing kits in low-rise housing construction

The article considers an urgent scientific problem, which consists in a fundamental structural contradiction between the strategic goals of the development of low-rise industrial construction in the Russian Federation at all stages of the life cycle of facilities and the established industrial and technological base of the industry based on the model of stationary house-building complexes. The purpose of the research is to develop and test tools for the formation of a geographically distributed network structure of production facilities of enterprises for the production of factory-ready housing kits, capable of overcoming the economic and logistical barriers of the classical model, manifested at all stages of the life cycle of industrial low-rise housing construction. Within the framework of the study, a toolkit was developed that includes a methodology for selecting reference territories and a mathematical optimization model solved by the "branches and boundaries" method. The practical testing of the toolkit was carried out using the example of a retrospective analysis of the emergency response in Tulun (Irkutsk region, 2019). A quantitative assessment of the effect of the proposed model was carried out by comparative economic and mathematical modeling of the basic (delivery from a remote DSC) and innovative (deployment of a mobile DSC on site) scenarios. As a result of the research, the economic, temporal and social effectiveness of the proposed network model has been proven. It is concluded that the developed toolkit is an effective means of improving the efficiency of life cycle management of lowrise residential construction and can be used to solve problems of both planned spatial development and rapid response in emergency situations.
