Development of a methodology underlying a deterministic model of construction work arrangements on the basis of the concept of an organizational and technological platform for construction

Introduction. Presently, intensively developing digital technologies can be contributed to theoretical models, engineering designs, as well as construction implementation methods. The article addresses the justification of a methodology underlying a deterministic model of construction work arrangements, designed to eliminate a methodological gap between theoretical methods of research and simulation, engineering methods of design and methods of implementing solutions to problems of construction processes. Materials and methods. Relations between the key sets of elements of construction processes were identified to justify the methodology, underlying the deterministic model of construction arrangements, using methods of the general theory of systems. Approaches to development of an organizational and technological platform in the construction industry and researches in the field of organizational and technological reliability of construction processes are also provided. Model elements are presented as a consolidated block diagram of methods, technological and administrative procedures, as well as construction process periods. The authors present a system for classifying theoretical models that are applicable to construction process research. Results. The methodology, underlying the deterministic model of construction process arrangements, is justified by a system of linear equations, describing construction process components. Construction process components are determined by the structural block diagram of construction process arrangement methods. Parameters and variables of equations convey a unified organizational and technological construction platform, and they can serve as a constituent of the criterion of meeting scheduled deadlines in the course of evaluating the organizational and technological reliability of the construction process. Conclusions. The methodology, underlying the deterministic model of construction process arrangements, based on the concept of an organizational and technological platform of construction processes, represents a structure of algorithms designed to coordinate decisions concerning construction processes, obtained using various methods. This coordination is implemented using sets of ratios between technological and organizational parameters of construction processes and the criterion of predicted time reserves needed for the implementation of current processes and related engineering operations, given that resources and time are still available according to the construction schedule.
