The description of technological process of production of cans of low pressure polyethylene. The results of studies on the estimation of the input technological parameters on the output parameters and characteristics of the product. The mathematical model of the technological process of obtaining products of high density polyethylene. The solution of problems of chemical-technological processes using the method of mathematical modeling, based on the strategy of system analysis. When conducting chemical-technological processes often important to know degree ᅟ completeness their completion , which in its turn, depends on distribution on time stay particle flow in ᅜ apparatus as some share flow can linger in machine and while others slip that directly associated withᅜ time contact and diffusion.

The article describes the main factors ranking sites by search engines. Using and analysing of these factors by developers of the sites gives to the high positions in results of delivery of search engines. Three groups of factors are specified and examined in the article: internal ranking factors, external ranking factors and behavioral ranking factors. The giving example of search engine ranking pages of Yandex and Google for the developed site consider these factors.

Keywords: the ranking factor, the sorting sites, the search engine optimization, the search engine, site optimization, Internet

Recently, in the process of creating a single information space worsened organization relevant databases in geographically separated units of one company, no common local area network and to allow for working with databases via the Internet. The main solution is to organize the synchronization of electronic data on external media.
The developed application allows an automated procedure to find differences in the databases of reference materials and assortments, add to the database of any of the divisions of the elements that are missing from it, and are available in the other areas.
The present article is intended for those engaged in the organization of a common information space in the field of design and technological preparation of production through the creation and administration of topical databases.  

Keywords: database, reference of materials and assortments, algorithm, synchronization, program, enterprise

"This article describes modeling of uniform system of design and technological preparation and production. The mathematical model is based on base of the theory of probability, the theory of mass service and mathematical statistics. Its basis is markovsky casual process. If the stream of events at the enterprise is stationary, without a consequence and ordinary, this process is called the elementary. The average size of a flow of information of each service is determined by the law of distribution of Erlanga, the stream density is determined by the enterprise, and production transition from a condition to a condition of shops and productions is estimated. When modeling a flow of information on movement of information and details at the enterprise classification of divisions was offered. After the analysis of their activity and a flow of information, details and documents the state graph of uniform system of design and technological preparation and production is constructed. Transitions were thus described and factors are appropriated. For each condition of system of a state graph limiting probabilities of conditions were calculated and Kolmogorov's equations are worked out. At integration of data of systems of the equations the probability of conditions of activity of divisions and production as time functions during every moment of time is defined."
