THE METHODOLOGY OF DESIGNING MODULAR STRUCTURES IN PRODUCTION USING PREFAB TECHNOLOGY

The article considers the experience of application of modular construction and factory ready buildings in Russia and abroad. The technologies of manufacturing modular structures and modern approaches to the automation of design processes are analyzed. Based on the analysis it is concluded that the level of implementation of information modeling technologies in the direction of industrial production of modules is insufficient. Accordingly, the purpose of this study is to improve the efficiency of solving the problems of life cycle management of modular objects at the stages of design and production. To achieve this goal, a review of existing production processes and methods of design automation, in particular the calculation of technical and economic parameters of the project was carried out. A methodology based on the use of simulation predictive model was developed and tested. The obtained results are analyzed, the possibilities and advantages of applying this methodology within the framework of industrial production using prefab technology are presented, and the directions of further research are formulated. The proposed methodology significantly accelerates the project development due to the systematization of data and increases the accuracy of calculation of project components. This allows specifying the consumption of materials and accelerating the decision-making process at all stages of design, also contributes to reducing the risk of errors and reducing total costs at the stage of production.
