Досліджено методи та алгоритми розв’язування задач впровадження економіко - математичного моделювання оптимального планування вантажоперевезень з метою підвищення ефективності роботи аграрних підприємств в умовах розвитку ринкових відносин. Охарактеризовано загальні підходи до постановки задач перевезень неоднорідних вантажів різними видами транспорту та наведено критерії оптимальності цих задач в сучасних умовах господарювання.
Показана необхідність удосконалення методів оптимізації планів вантажоперевезень, пов’язаних з побудовою моделі чотирьох індексної транспортної задачі, кінцевим результатом якої буде можливість отримати оптимальний план при заданих умовах і вести розрахунок не для всього запасу продукції, а для тієї кількості продукту, яка перевозиться із кожного пункту за одну поїздку.
Methods and algorithms for solving problems of introduction of economic-mathematical
modeling of optimal planning of cargo transportation in order to mathematical modeling of optimal
planning of cargo transportation in order to mathematical modeling of optimal planning of cargo
transportation in order to increase the efficiency of agricultural enterprises in the development of
market relations are studied. The need for additional conditions for creating a model of optimal
transportation of two types of cargo has been established on the basis of a number of additional
conditions. The scheme of the developed economic and mathematical model for calculation of
optimum distribution of cargo transportations is developed. The need for additional conditions for
creating a model of optimal transportation of two types of cargo has been established on the basis
of a number of additional conditions. The scheme of the developed economic and mathematical
model for calculation of optimum distribution of cargo transportations is developed. The essence
of improvement of methods of optimization of plans of cargo transportations connected with
construction of model of four index transport problem which final result will be a poor. Whencreating the model, it was established that there is no influence of insufficient load capacity
of vehicles on the optimal distribution of work volume in tons-kilometers. Unity to receive the
optimum plan under the set conditions and to conduct calculation not for all stock of production,
and for that quantity of a product transported from each point is shown for one trip. The general
approaches to optimization of transportation of straw and grain cargoes by the agricultural
enterprises are characterized and the criteria of optimality of the received plan are resulted.
The necessity of using mathematical modern methods in planning and forecasting of processes in
the agricultural sector, namely the optimal transportation of products from fields to warehouses,
elevators, farms, poultry farms. The growing requirements for transportation conditions that
require in-depth research and calculations have also been studied. The formulation and general
approach to the solution of a multi-index transport problem in general form are shown, which
implies a restriction on each of the indices and observance of a number of conditions so that
the problem has at least one admissible solution. The algorithm of reduction by a number of
simplifying propositions of a nonlinear problem to a linear one, as well as its solutions with a
minimum number of iterations, is established.
