A new structural material for the production of ventilated facades (ventilated fences)-granulated blast furnace slag, which has high structural, thermal and adsorption properties, allowing to signifi cantly increase the energy-saving and environmental characteristics of ventilated fences and, accordingly, facades of buildings and structures. Developed by the innovative design of ventilated facade (ventilated fencing) based on blast furnace slag, allowing the clear air of the street from a signifi cant part of nitrogen oxides, sulphur oxides, oxides of carbon, soot particles and dust, to reduce the amount of heat delivered to the building in summer and heat loss in winter, which greatly improves the environmental and economic performance of buildings.

One of the most important economic tasks of construction activities actors is the correct estimation of their initial state in terms of the possibilities for further development. The solution of these complex problems under the conditions of limited resources puts forward the problem of quantitative and qualitative measurement of available resources and productive and technological potential of organizations. The paper discusses a system analysis of the construction organization and the components of the productive and technological potential as subsystems that have a qualitative and quantitative measurement of the maximum possible effi ciency of resources usage by a construction organization under conditions of the rational construction management and the interaction of business entities in the investment sector.

In this paper we consider the modifi cation of the method of planning the A-star path for transport and aerospace robots. It is necessary to take into account obstacles in the local neighborhood of aerospace robot, but not suffi cient for the rational path planning. The essence of the modifi cation is to use additional information about the features of original cell array. This additional information is represented by binary fl ags. They represent obstacle-free rows and matrix columns. The modifi cation allows you to build paths that include straight sections of free cells. The main feature of this method is the use of bitwise logical operations on cell values.
