dc.description.abstractУ статті представлені результати теоретичних досліджень отримання максимального прибутку монтажно-заготівельним підприємством в процесі виготовлення та реалізації трубної заготовки для монтажу системи вентиляції у виробничому приміщенні невеликого об’єму. Наведено графічні та аналітичні залежності процесу. Результатами досліджень обґрунтовано отримання максимального прибутку під час виготовлення та реалізації вентиляційної трубної заготовки цілого спектру діаметрів монтажно-заготівельним підприємством. Метою роботи є підвищити ефективність монтажу системи вентиляції у виробничих приміщеннях невеликого об’єму, визначити максимальний прибуток для монтажно-заготівельного підприємства в процесі виготовлення та реалізації трубної заготовки різних діаметрів вентиляційної системи за наявності декількох обмежень – за матеріалами та трудовими ресурсами, а також виявити шляхи підвищення ефективності монтажу системи вентиляції у виробничих приміщеннях невеликого об’єму та обґрунтувати методику їхнього розрахунку. Встановлено кількісні характеристики цільової функції при заданих вихідних умовах та отримано розрахункові залежності для визначення параметрів цільової функції. Отримані результати дають змогу визначити оптимальні параметри величин при заданих обмеженнях щодо матеріалів та трудоємності процесу виробництва. Застосування графічного методу та симплекс-методу для визначення необхідних параметрів заготовки дозволяє значно підвищити критерії ефективності проведення заготівельно-монтажних робіт і тим самим зменшити кількість трудових ресурсів та витрату матеріалів для виготовлення і монтажу вентиляційної системи загалом.
dc.description.abstractThe 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.
