Increase of ventilation systems procurement and installation works efficiency

The article presents the results of theoretical research on obtaining of the maximum profit by the installation and procurement company in the manufacture and sale of pipe billets for the installation of ventilation systems in the production premise. Graphical and analytical dependences are given. The results of research substantiate the receipt of the maximum profit in the manufacture and sale of the ventilation pipe billets of the different diameters by the installation and procurement enterprise. The purpose of the work is to increase the efficiency of ventilation system installationin production facilities, to determine the maximum profit for the installation and procurement company in the manufacture and sale of pipe billets of the different diameters of ventilation system in the presence of several restrictions on materials and manpower, identify ways to improve installation of ventilation system in production facilities of small volume and justification of the calculation method. Quantitative characteristics of the objective function under given initial conditions are established. The calculated dependences for determining the parameters of the objective function are obtained. The obtained results allow to determine the optimal parameters of the values at the given restrictions on materials and labor intensity of production. The maximum profit in the manufacture and sale of ventilation pipe billets of different diameters by the procurement and installation company is determined. Using of the graphical method and the simplex method to determine the required parameters can significantly increase the efficiency criteria for procurement and installation work and thus reduce the amount of labor and material consumption for the manufacture and installation of ventilation systems.
