Opis:
An appropriate solving the transport organization in agriculture requires, among others, to work out the method for transportation means work organization. Issues associated with transportation means work organization is impossible to be optimally solved by a controller in the case of developed transport network, instead they require computational techniques for fast information processing. One of such methods is presented in the paper as a system for sugar--beet transport to sugar works. In sugar industry, large amounts of raw material are transported between sugar-beet producers or storage centers and processing works. Presented program makes possible to select transportation means for carrying the sugar-beet, and then working out the schedule of routes realized by vehicles. The paper presents the management system of sugar-beet transporting to the sugar works that optimizes the transportation means work. Minimization of courses length, because it directly affects the reduction of transportation costs by means of decrease of fuel and other exploitation parts used, shortening the driver's work-time, and decrease of fees for vehicle rental. The system was verified using real data for a given day, which confirmed the correctness of the software functioning. Working out and launching the software required to write databases containing necessary information on: sites the material was received from, amount of transported loads, transportation means, loading/reloading machines and devices along with their technical and exploitation parameters, as well as the project required to draw digital map with all analyzed purchase centers, sugar works, and all the road network. Minimization of routes was accepted as a purpose function, because it directly affects the reduction of transport costs through reducing the fuel and other exploitation means used, shortening the driver's work time or decreasing the fees for vehicle rental. The system was verified using real data for a particular date, which confirmed the correctness of the software functioning. Activity aiming at reducing production costs through elimination of unnecessary expenditures resulting from bad work organization would contribute to the improvement of competitiveness of Polish agriculture and enhancing its opportunities on EU markets. Proposed system for sugar-beet transport management at Sugar Works is an example of the system meeting such expectations.

Opis:
Works upon computer systems for agricultural goods transport management require, among others, an appropriate preparing the data on transportation network within transport optimization system. Such transportation network is very complicated and contains a variety of detailed information on purchase centres, to which cereals are supplied by farmers; stores, to which purchased cereal is transported; and transportation means that take part in a transport of purchased cereals. Since 80's decade of the 20th century, works upon the optimization of agricultural goods transport process have been performed at The Department of Agricultural Machines and Devices, University of Life Sciences in Lublin. That time, many transportation systems based on various optimization methods were worked out. Particular versions were written in different programming languages, subsequent versions of data processing procedures were worked out and different methods (more and more advanced) for computer map of the area were applied. All data referring to centres the goods are received from, and supplied to, upon the transportation means should be entered into the database in such a way that the software could use them during calculations. The software perfectly facilitates the process of data input. In a simple and clear way, it ensures the accessibility to particular files as well as movements among them. Its role is to generate files used subsequently to calculations in optimization software.

Opis:
The paper presents the procedure for solving a transportation task. The optimization was carried out in two phases. In the first one, a preliminary flow matrix was achieved on a base of the information on the demands and supplies values as well as transport costs, whereas some shifts within the preliminary flow matrix were made. All changes resulted in an optimum matrix, for which Zx function held the lowest possible value. Presented method appeared to be efficient for solving the transportation tasks of particular type.
Celem pracy było przedstawienie postępowania właściwego dla rozwiązywania zadania transportowego. Działania optymalizacyjne przeprowadzono w dwóch etapach. W pierwszym z nich uzyskano wstępną macierz przepływów, na podstawie informacji o wielkości popytów odbiorców i podaży dostawców oraz wartości kosztów przewozów. W drugim etapie dokonano przesunięć we wstępnej macierzy przepływów, uzyskanej w etapie pierwszym. Zmiany te doprowadziły do uzyskania macierzy optymalnej, dla której funkcja Zx przyjęła najniższą wartość. Przedstawiona metoda okazała się być skuteczna przy rozwiązywaniu zadań transportowych określonego typu.

Opis:
Designing the connections between suppliers and receivers of a product is an important issue during the process of physical goods distribution. Selected solutions directly affect the level of costs expended for a transport process and indirectly the price of distributed goods, which determines the competitiveness of a given product. This study presents procedures making possible to plan the transport of goods under circumstances of imbalanced supply and demand taking into considerations existing restraints such as need to bring a part or a whole lot from a supplier (or suppliers), as well as necessity to deliver required quantity of ordered product to the receiver. The efficiency of the method was analyzed using the example of shifting products among three manufacturing enterprises and five wholesalers having the demands that suppliers cannot match. Additional factors considered in analyzed example were the requirements imposed by receivers, among which one needed to have 60% of declared order, while two others the complete declared order. Operations aiming at creating a preliminary flow matrix were made with a help of Minimum Matrix Element Method. The optimum solution was achieved applying Matrix Graph Method. The result is an optimum plan of connections among manufacturing enterprises and wholesalers. Meeting the requirements imposed by receivers indicates the effectiveness of discussed procedure.
