The research paper offers an electric chart, that is a model of a transport task, one of the widely widespread tasks of the linear programming. Its basis is made up of two groups of current sources, one of them imitates producers, another imitates consumers. The exits of sources of one group by means of chains with resistors are added to the entrances of current sources of the second group. Leads of sources, that do not join connecting chains, unite, forming the reserved chain from all elements. The values of current sources set to the equal values of amount of product for corresponding producers and consumers. The numeral values of electric resistance of resistors set to the equal values of transport charges. The coincidence of mathematical determination of current is well-proved in the offered model, with a mathematical model on the basis of that distribution of load in a transport task is found. Therefore the possibility to define the plan of load transporting on rails on the basis of determination of current in the chains of model is created. In terms of calculation of a specific transport task given by an electric model, the possibility of the use of solution algorithm that widely used in the linear programming is shown. Basic action at the task decision on models is breaking of chains. It presupposes a zero load in accordance with the solution algorithm. On application of model there is no necessity to count up a load in chains on the intermediate stages, to fix bits and pieces of product for suppliers or its shortage for consumers. "Correct" values of current in the abandoned chains are necessary and arise up automatically due to an action in the electric circles of model of Kirchhoff law in relation to a current. Application of a model, built on other principles will allow to find new methods and approaches to the solution process. As an example, in solving a specific transport task two variants of determination of elements of the reserved chains in are possible to conduct the redistribution of load on the stage of optimization of base plan. |
