he design of multifunctional technological systems is based on well-known theories of operations research using production building systems of various levels and purposes, as well as system engineering, decision-making and optimization methods. Taking into account the provisions of efficiency and reliability systems.Production building systems, as a class of functional systems, are created and designed to implement certain tasks, which can be specialized (one task) or multifunctional (several tasks) The result of the formation of such systems is the final useful result, which is achieved through interaction and, accordingly, the mutual influence of its participants. Dynamics and the ability to change in the process of system implementation are provided by models that have similar structures and sets of indicators and parameters for the subject and product of work. Its main component can be shown in the form of systematized information about the phenomena and patterns that manifest in them. They form the theoretical foundations of the relevant aspect of technology.The decomposition of complex systems into component subsystems in order to optimize their elements is solved by formalizing design procedures and creates a method of designing multifunctional systems.Expanding the universal capabilities of construction and road machines by equipping them with additional interchangeable working bodies allows for a flexible approach to the design of multifunctional technological systems.Their effectiveness is especially evident in the design and implementation of multifunctional systems during earthworks, landscaping works, as well as the construction of agro-industrial structures from light and especially light metal structures
