In the article on the example of the firm which is engaged in production of plastic windows business processes modeling of production companyis described. The analysis and modeling of business processes of the company are carried out, the charts of the IDEF0 and DFD model created by means of the software product "AllFusion Process Modeler" are presented, information streams of the organization are shown. Shortcomings of various aspects of activity of the organization are revealed. Model of an information system is realized: requirements and problems of IS are formulated, the functional model is developed (by means of the AllFusion Process Modeler software product).

Keywords: production company, production, modeling business processes, IDEF0, DFD, software product, business process, chart, organization

In the article techniques of research of the high-speed modes of vehicles during road accidents and also problems of stability of vehicles are described. On the example of the real road accidents which happened in the city of Tyumen were applied laws of theoretical mechanics for studying and an explanation of the reasons of road accidents.

Keywords: road accident, theoretical mechanics, stability, speed mode, dynamics, theorems of dynamics

Applying of teaching programs in study of theoretical mechanics is considered in this article; the main topics included in the teaching complex and it's structure (consists of three parts) are shown. Work algorithm of teaching program is presented, the block diagram of the algorithm for the "Projection of force on the axis" is shown, the shape of the output rules of theoretical mechanics is given, the output window of test question is presented for example, the main advantages of applying complex of teaching programs and the future prospects of its development are shown
