Environmental graphic method for creating area of permissible impact

Abstract

The methods of ecological optimization of influences developed by the author are presented, including: - graphic method of creation of area of admissible influences by the solution of problems of linear programming; - model of identification of dangerous influences simplex method; - method of formation of steady control systems of ecological safety of construction. On simple numerical examples possibilities of mathematical modeling of environmental pressures at stages of life cycle of construction objects are illustrated. In the paper, linear equations of action with constraints and with two variable factors of influence were considered. If we go over to linear relationships with three variable factors of influence, then they will describe the plane in the three-dimensional impact space; the system of linear constraints is a polyhedron, as the domain of permissible impacts in the three-dimensional impact space. Studies carried out by the graphical method of constructing the region of permissible impacts in solving ecological problems of linear programming have shown its effectiveness and visibility, in comparison with the results obtained by calculation. The most effective is the development of environmental safety management systems for construction related to sources, definitions and categories of wastes, as well as the composition and treatment of waste streams, in order to promote waste prevention and the establishment and implementation of mechanisms to prevent generation and minimize waste, as well as recovery and recycling systems waste construction industry.
