VEGETATION AND PLANT MATTER OF RAISED BOGS IN FOREST-STEPPE ZONE IN THE SOUTH OF WESTERN SIBERIA [№ 3 ' 2017]
The forest-steppe zone within the Novosibirsk region of Western Siberia was surveyed. The following typical mire ecosystems in close contact with each other are functioning: oligotrophic pine-dwarf shrub-Sphagnum raised bogs (ryams), reed floodplains and mesotrophic fens around secondary lakes in ryams. Calculation of the productive parameters of the pine stand was calculated using young model trees. Photosynthesizing mass of pine trees was 120 g/m2, above-ground lignified organs — 344 g/m2 with trunks contributed of 66 %, and the trunk stock under the moss cover was 64 g/m2. The stock of dead branches was 19 g/m2. The total stock of above-ground mass of trees was estimated as 464 g/m2, with contribution of pine trees in the total aboveground phytomass of 36 % in ryams. Pine primary production was calculated as the sum of the current year needles and shoots and reached 47 g/m2 a year, ie 14 % of the total aboveground production in the ryam. In all types of mire ecosystems the phytomass, mortmass and net primary production were evaluated. Stocks of aboveground biomass varied from 300 to 2,200 g/m2, below-ground phytomass — from 1,200 to 4,200 g/m2. Net primary production varied from 500 to 3,000 g/m2 a year, minimal production is produced in oligotrophic ryams, and maximal production is produced in mesotrophic and eutrophic mires. Phytomass stocks and production were estimated for dwarf-shrub, grass and moss layers. Value of standing crop is similar in the studied ecosystems and estimated as 4,133 g/m2 in fens, 4,032 g/m2 in floodplains, and 3,681 g/m2 in the ryam.

IMPROVING THE QUALITY OF OPERATIONAL MARKETING ACTIVITIES ON THE BASIS OF THE METHODOLOGY OF FORMATION OF THE PRODUCTION PROGRAM [№ 4 ' 2015]
In the present study, the authors proved the need to improve operational marketing activities through the development of tools and methods to influence the product, price, promotion and distribution. The purpose of research — to improve the operational marketing activities. The object of study — the marketing activities of the refinery. Subject of research — the means and methods of operating marketing activities that allow to develop a method of formation of the production program. The study developed a method of formation of the production program of the enterprise, which is realized by linear programming using spreadsheet Excel Microsoft Office. The technique includes economic and mathematical optimization model, which has a number of restrictions on raw materials, production possibilities, the minimum volume of production and number of employees. Optimization criterion adopted to maximize profits from sales. In developing the methodology used by the authors receiving equalization time series using the moving average with subsequent approximation that allowed us to obtain predicted values of sales in the next period of time (determined by the quality of the approximation model coefficient of determination). Technique of formation of the production program has been tested on the refinery for the production of oils and lubricants for various industries. Predicted values obtained in production volumes for each product, which significantly improve the quality of operational marketing activities of the enterprise in the preparation of a marketing plan for each product. The main advantage provided by the technique is that it can be implemented in any industrial undertaking, and that it does not require specialized software and implemented using spreadsheet Excel Microsoft Office.

ABOUT IMPROVEMENT OF AUTOMOBILE OPERATIONAL MATERIALS QUALITY [№ 10 ' 2014]
In article it is established that for the operational materials made on a prescription basis, the effective instrument of improvement of quality and competitiveness will be application of the functional and cost analysis. It will allow consider object as part of the functions which are carried out by it, to create functional model of object of research, to reveal the most essential functions, thereby to define zones of concentration of useful and harmful expenses which exception will help to increase competitiveness and quality of operational materials.
