Mathematical model of the equipment process of railcars by train frames

One of aspects of transport service of rolling production of the metallurgical enterprises is considered i.e. process of the railcars' installation by the multicurrent assets of fixture (frames) intended for placement on them sheet rolled metal. The unevenness of daily production amounts of these products by sheet-rolling shops and also significant increase in number of the railcars requiring the equipment frames are revealed. Determination of the maximum of handling capacity of the points railcars installation by frames in case of limited production resources becomes relevant. The labor and technical resources are considered as the production resources involved in this process. Determining the maximum handling capacity of is carried out with developed optimization mathematical model. The description of proposed linear optimization model is provided. The factors influencing parameters' values of the modelled process are revealed. The result of experimental calculations on the example of a railway station "Chugunnaya" of OJSC Magnitogorsk Iron and Steel Works and its comparison to actual data are presented.
