The purpose of this work was to build a model of industrial plant management and develop a schedule plan based on it. The paper considers a controlled model of product flows at an industrial enterprise. The model describes the interaction between various objects at the enterprise: production plants, manifolds, overpasses, piers, transport. In addition, the model specifies the composition and proportions of the components of raw materials and additives for each type of manufactured product, as well as physical constraints on the objects involvedin the production process. This brings us to the model of both the quality functional and equality and inequality constraints in the mathematical formulation. After building the model, the original control problem was reduced to two problems: direct and inverse. The numerical solution of both is provided in a close relationship between them. The study uses the findings from the theory of mathematical modeling, linear algebra and optimization theory, and leads to the development of the technique of building models of scheduling at an enterprise and numerical methods for solving the corresponding management problems. The research results are of great practical importance and can be used for effective management of the production process in many industries

The art of chisel mask is developed in Tumpang Malang area as part of dance costume fairs, puppet show andcultural ritual, although in its development, this mask sculpture is also sold and become a tourism commodity. The potentialsales of mask sculptures is increasing, especially because of the demanders are foreign tourists, cultural enthusiasts andcomponent of tourism activities. That is, Topeng Malangan has the potential to be developed as an export commodity. Thesales system is still limited to cultural events or when there is a visit of education and tourism to the arts-padepokan. Thisprompted some people around the padepokan to start a home industry to meet the availability of the mask. In general, theproblems encountered by the craftsmen are (1) availability of raw materials, especially for suitable wood species, (2)production equipment, especially for pre-carving process and preservation of product, (3) there is no standard marketingscheme, (4) does not have a business management system, and (5) highly skilled craftsmen are still very limited. The solutionsoffered are divided into three stages: (1) technological strengthening, including strengthening production process technologyand increasing the number of craftsmen; (2) establishing business management; and (3) establishing trademarks, copyrightsand product marketing expansions

Sugar Cane Juice

Nowadays petroleum dependency in transportation is widely discussed all over the world. Atmospheric pollution and global warming are deleterious consequences of gasoline consumption. Ethanol is a natural substitute fuel that has been increasingly used. One of the most important raw materials used for ethanol production is the sugar cane. The exothermic fermentation reaction of the sugar cane juice in the ethanol production process requires a rigorous temperature control. This control is usually made by using cooling water from cooling towers. The heat released from cooling towers not only has an economical cost as well as it contributes to the global heating. Steam ejectors can substitute cooling towers thus improving the ethanol production plant efficiency and reducing world heating. Furthermore, steam ejectors are smaller, cheaper and are very simple equipment when compared with cooling towers. Furthermore, its use provides an improved thermal efficiency of the production plant resulting in the reduction of the global warming effects. In this work the use of steam ejector is proposed for the fermentation cooling of a typical Brazilian sugar and ethanol production plant. The steam which feeds the steam ejector is obtained from the plant utilities and the low temperature obtained from steam expansion within the ejector is used for sugar cane fermentation process cooling. The steam ejector discharge heat is recovered as it is used to sugar and ethanol production process heating. The sugar and ethanol production plant overall energy fluxes either using cooling towers as well as using steam ejectors are presented and the results are compared and discussed.

Проведена сравнительная оценка времени пребывания коров-первотелок в доильном боксе с минимальной, максимальной и средней продолжительностью молоковыведения из всех четвертей вымени высоко- и низкопродуктивных при доении на автоматической установке «Astronaut A». У высокопродуктивных животных по сравнению с низкопродуктивными установлено увеличение длительности исследуемых четырех периодов молоковыведения на 34,5—60,6%. Между изученными временными параметрами молоковыведения выявлена тесная взаимосвязь (r=0,69-0,98; P<0,001). Выведено уравнение регрессии между периодом доения, рассчитанного путем определения максимальной продолжительности выдаивания одной из четвертей вымени, и средней продолжительностью молоковыведения из всех четвертей вымени (r=0,96; P<0,001). Установлено, что доля технологических операций, не связанных с процессом молоковыведения, составляет 24,1—31,6% от длительности периода пребывания в доильном боксе. Показана возможность использования для оценки интенсивности молоковыведения на автоматической установке «Astronaut A4» наряду с продолжительностью пребывания коровы в доильном боксе показателей максимальной и минимальной продолжительности молоковыведения из одной четверти вымени, а также средней продолжительности молоковыведения из всех четвертей вымени у высоко- и низкопродуктивных коров. Comparative assessment of the time of stay of first-calf cows in a milking box with minimum, maximum, and average duration of milk production from all udder quarters with high and low productivity when milked using the Astronaut A automatic device was carried out. When compared to low-productive animals, high-productive ones showed the increase in duration of the studied milk production periods by 34.5—60.6%. Close relationship between the time-based parameters of milk production was established (r=0.69-0.98; P<0.001). Equation of regression between the milking period, calculated by determining the maximum milking duration of one of the four udder quarters, and the average duration of milk production from all four udder quarters (r=0.96; P<0.001) was derived. It was established that the share of technological operations not connected to milk production process amounts to 24.1—31.6% from the duration of stay in the milking box. The possibility for using the parameters of maximum and minimal duration of milk production from one of udder quarters, as well as the average duration of milk production from all four quarters of the udder in high- and low-productive cows along with the length of cow’s stay in the milking box for the evaluation of milk production intensity using the Astronaut A4 automatic device was shown.
