Blending Process

Weighing and blending process is an important step of industrial and agricultural production. Traditionally, the simplest way of weighing and blending is to weigh the variety of raw materials manually and mix them together. There are some disadvantages of this method, such as measuring inaccurate, low productivity and labor-intensive. The comparatively advanced method is making use of the computer control technology to realize automatic weighing and blending according to predetermined formula. According to the production characteristics and technological requirements of a certain chemical product, an integrated control system of weighing and blending for liquid raw material based on DCS (Distributed Control System) is developed in this paper. The system is composed of IPC (Industrial Personal Computer), ADAM data acquisition modules, weighing sensor and execution unit. The 485 bus is adopted to transmit data between the different equipments. With the support of SQL Server 2000, the process control and production management of weighing and blending are realized with C++ builder 6.0. The integrated system can be divided into three subsystems, namely, the process control subsystem, the production monitoring subsystem and the production information management subsystem. The application result indicates that this system improves the production efficiency and stabilizes the production process.

Outlines the problems and self-questioning facing the process control engineer when deciding to replace the computer control system which he has found difficult to justify over the last decade. Should he return to conventional analogue instrumentation or choose a microprocessor based control system? Having highlighted in his mind the problems with his computer based system, has he missed the majority of the advantages which a digital system brings? Does he realise that a major manufacturer has been acutely aware of his problems and has sought to eliminate them with the design of any new system? Can his faith be restored?

The article justified the necessity of developing a strategy for the improvement of the sugar beet subcomplex of the region on the base of the determination of the close relationship between beet-growing farms, enterprises engaged in the delivery, processing and sale of manufactured products. According to the authors, the optimization of the raw material zone should include the principle of maximum loading of sugar mills, taking into account the raw materials produced in the region, optimizing transport costs for its delivery. The analysis of the sown area, productivity and gross yield of sugar beets gives us the idea that the region takes the tenth place among the largest producers of sugar beets. The yield and gross yield in 2019 in agricultural enterprises amounted to 459.6 centner / ha, 2231.9 thousand centner (an increase of 13.6% and 9.4% compared to the level of 2018).For P(F)E, the average increase is 40%, which corresponds to 481 centner / ha, 18.3 thousand tons. The average sugar content of beets during acceptance and processing ranges from 17.96 to 18.3%, the sugar yield is 15.63%, the sugar content in molasses is 1.68%, and the average daily productivity is 16.11 thousand ton / day, loss in production is 1.27%. The authors found that the production efficiency of the sugar beet industry is directly connected with the growth of labor productivity, the introduction of modern technologies, cost reduction, and thus, each farm has the opportunity to get additional profit. One of the main problems in the agricultural sector of the economy is the use of available resources to obtain the largest number of products. In our opinion, the production efficiency of sugar mills is closely interconnected with the constructed logistics routes for the transportation of raw materials with the exception of repeated shipments, the proportion of sugar beets in the sown area, and the reliability of suppliers. In our opinion, the efficiency of sugar mills production is in close connection with the built of the logistic routes for transportation of raw materials with the exception of repeated transportation, the specific weight of sugar beet in the structure of the sown area and the reliability ensuring of suppliers. The problem of the effective development of the sugar industry is relevant and priority in solving regional policies, the implementation of which will not only eliminate the emerging imbalances and reduce imports, but also support the domestic producer.

Neither the development of the world economy nor the availability of raw materials can guarantee the stability of economic development and a high level of social welfare. Now Kazakhstan faces the task of accelerated development of national economy sectors that give a multiplicative effect (the share of agricultural products in the country's GDP should grow 5 times by 2050), including the agro-industrial complex of Kazakhstan has a great potential to become a new driver of economic development. Therefore, the agro-industrial complex of Kazakhstan needs sustainable development of export-oriented agricultural production that is competitive on the world market. Despite the solution of many theoretical and applied problems reflected in the works of these authors, a General approach to the classification of organizational reserves for improving the efficiency of production of scientific-intensive products is not currently formed, and the issues of forming a mezzanine for identifying and using, and evaluating the level of production efficiency require further improvement. The purpose of the research is to develop theoretical, scientific, methodological and practical provisions for the formation of a production management system of innovative potential based on improving the competitiveness of the agricultural industry, aimed at ensuring food security in Kazakhstan. The article shows that the innovative type of economic development requires the development of a competitive innovative potential product, the implementation of the principles of continuous improvement, the search and use of the organization of production for its effective production. The necessity of forming mechanisms for identifying and using organizational reserves to increase the efficiency of production of innovative potential products is also determined. This opened up the possibility of creating and developing conditions conducive to the mobilization of domestic reserves.

Modern realities of enterprises operation actualize the need to optimize logistics chains by intensifying administration actions of managers to detail logistics expenditures and automate the business process. At the same time, the functional focus of the company's interaction with partners in supply logistics is to perform tasks aimed at minimizing logistics costs. Minimization of logistics costs, as well as the introduction into management practice of other principles of logistics (timeliness of deliveries, assurance of quality and declared deadlines) creates additional competitive advantages of the enterprise and optimizes its entire business process. Under these conditions, the issue of management approaches is actualized, which makes it possible to increase production flexibility, adapt the enterprise to competitive conditions, optimize flow processes, integrate elements of the production management system, ensure maximum capacity of production facilities, optimize basic and auxiliary operations, manufacture products in accordance with existing orders and fully meet the expectations of the main stakeholders of the enterprise. The vector of application of management approaches should be based on definite, specific for a particular business unit, measurable parameters of operating activities, which would be indicators of overall performance of the enterprise and informationally integrate the effectiveness of logistics and operating systems as a whole. The article proposes a methodical approach to the formation of a system of indicators for a comprehensive assessment of raw material procurement (cost of the procurement process; quality of raw materials; the degree of satisfaction of final users) as well as an algorithm for their calculation. The practical significance of calculating such indicators is the synthesized application of indicators of efficiency of logistic and production systems of the enterprise as a whole, as well as the application of differentiated assessment of significance of indicators according to the established rating scale depending on the functional orientation of purchased products for the production process.

The principles of blending control are explained with particular reference to a control scheme currently being implemented by G.E.C. Computers & Automation Ltd. for Skanska Cement AB at their Limhamn cement works. The control principles can, however, be applied to other blending plants. The Limhamn blending process is briefly described in order to give an appreciation of the control problems involved. The computer, instrumentation and X-ray analysing systems are outlined. The iterative optimiser is explained. This calculates set points for the material flows which, when implemented, result in manufacture of slurry with correct chemical composition at minimum cost. On-line regulating techniques which control the blending machinery are described. The regulating programmes maintain material flows at their calculated set point values. They also control water addition in order to keep slurry water content constant. Distinct advantages are to be obtained by the separate implementation of the optimising calculations or the regulating control, but the two are complementary, and to obtain maximum benefits, a computer control scheme should include both.

Cassava is becoming increasingly important as an industrial raw material in China. However, an insufficient supply of cassava raw materials and the expanding demand for cassava in downstream-processing industries restricts the development of the cassava industry in China. This paper studies how to increase the scale of cassava planting and promoting cassava production efficiency using output-oriented Data Envelopment Analysis (DEA) modeling. Overall Technical Efficiency (OTE), Pure Technical Efficiency (PTE), and Scale Efficiencies (SE) of the cassava-production system in the major cassava production areas of China are calculated using Variable Returns to Scale (VRS). Results reveal that, in addition to the Guangdong province, the OTE of Guangxi, Hainan, Fujian, Yunnan, and Jiangxi is inefficient, with an OTE of less than 1. The largest cassava-planting province, Guangxi, has the lowest SE with 0.551. The PTE of Guangxi is close to the minimum with 0.344. The OTE of Guangxi is also the lowest among the five provinces with 0.190. This study also presents ways to improve production efficiency. Results reveal that Guangxi has a large ratio of transverse adjustment on average. In the Guangxi province, 1.70% of the service cost and 1.72% of the labor cost need to be eliminated to keep the current output scale. Meanwhile, service and labor costs need to be reduced by 3164.85 and 3209.92, respectively, to achieve the best production efficiency. Further industrialization and large-scale cassava cultivation, increased yield, and strengthened cooperation with the Association of South East Asian Nations (ASEAN) and Africa are suggested as policy options to improve the cassava system in China.

Cargo Transportation

The economy of the Murmansk region retains its raw material orientation, as it is justified by the region’s natural resources and industrial potential. Economic activity of mineral-resource enterprises and those mining ores of ferrous and non-ferrous metals is going to remain the dominant sector of the regional economy for a long time due to the geological and economic characteristics and natural and climatic features peculiar to this area. The region is endowed with various natural resources. On the Kola Peninsula there are more than sixty major deposits of various types of mineral raw materials with more than three dozen extractable resources, the most valuable of which include copper-nickel, iron, apatite-nepheline ores and ores of rare metals. Production management and transportation of raw materials require well-developed infrastructure, creating an integrated transport system, that is why it plays a strategic role in the economy of the Murmansk region. It is connected with the fact that the region is predominated by industries focused on producing and delivering considerable volumes of raw materials and metals outside the region. In these circumstances, every enterprise plans and arranges transportation of cargo by various means of transport. Railway transportation plays a significant role as it provides round-the-clock cargo transportation from senders to recipients fulfilling clients transportation requests regardless of weather conditions.Therefore, the important scientific task is analyzing the cargo base and finding solutions for improving the existing and creating new designs of wagons and containers for railroad transportation of cargo, taking into account spatial directions of cargo flows, which is the purpose of this article. The authors have proposed options for modernization of wagons and designs of composite containers that possess scientific novelty, as the current state of the railroad transport system requires modernization.It is impossible to achieve effective economic performance of an enterprise that works in the sphere of mining and processing of mineral raw materials without creating a proper transport component that requires its own development. The implementation of the given proposals will allow the enterprises to increase the volume of cargo transportation which in its turn is going to have a significant impact on socio-economic development of the region.
