This paper establishes a parametric model on the motor hanging seat structure by pro / ENGINEER software, and then optimizes the structure of the hanging seat by the weight of the hanging seat as the objective function. Taking into account the stress and displacement constraints in the optimization process, the weight of the hanging seat is greatly reduced after being optimized. It is practical significance to save a large amount of raw materials for the mass production and to reduce production costs and create higher economic efficiency.

Intensive Breeding

AbstractIntensive breeding is related to formation of considerable amount of manure which may be used as a natural fertilizer. Manure fertilization may cause reduction of the amount of applied mineral fertilizers and thus reduction of production costs. It may particularly relate to the species with great fertilization requirements such as winter rapeseed. The objective of the research was to compare economic efficiency of rapeseed production in two farms which use different fertilization variants. In one, only mineral fertilizers were used and in the second one – mineral fertilization was supplemented with manure organic fertilization. The use of manure caused reduction of expenditures on materials and raw materials used in production, in particular of fertilizers. At comparable yields obtained by two farms, technology based on manure fertilization proved to be more efficient.

Common Information

The relevance of logistics and increasing interest in its study are explained by the possibilities that increase the efficiency of Materials Science Systems, which reveal the use of the logistics method. Logistics reduces the time intervals from the purchase of raw materials and semi-finished products to the delivery of finished products to the consumer, contributes to a sharp reduction in inventory. The use of logistics speeds up the process of obtaining information and improves the level of Service. As foreign experience shows, logistics occupies a strategically important place in modern business. Many professionals who have achieved success in this field move to higher positions in the management of the company. Currently, the traditional functional areas of logistics in leading firms are combined into the basis of a common information and computer platform, creating a system of Strategic Innovation (Innovation). The logistics service is comprehensive. This includes transport, warehouse, inventory management, personnel Management, Information System Organization, commercial activities, etc. Each of these functions has been thoroughly studied and described in the relevant industry order. The novelty of the logistics approach is the basic relationship. The purpose of the logistics method is the continuous management of material flows. The introduction of logistics management methods in entrepreneurial practice allows many firms to reduce all types of stocks of production, equipment and products sold, accelerate the turnover of working capital, reduce production costs, reduce the costs associated with distribution, and ensure full satisfaction of consumers with goods and services. From this point of view, the relevance of the research work can be traced. In this regard, this study is relevant and relevant. Scientific novelty and practical significance - development of proposals for improving logistics at enterprises of the Republic of Kazakhstan.

Using of Pro/E Integrated Mechanical Structure Analysis Module, the structural analysis of scraper and brush on picking unit under a certain load of stress and deformation and optimized analysis of some primary parts were performed. The size and distribution of stress field were calculated, which could provide references for the physical prototyped and reliability design for product design. Moreover, it optimized the size of scraper and brush on picking unit that has some practical significance for structural optimization design. So the performance of structure of the designed model can be evaluated，researched and optimized in a real working environment.

The article is devoted to reengineering of technological processes - a method of their qualitative transformation on an innovative basis, which in turn assumes the availability of tools that make it possible to establish the economic efficiency and technical capability of such transformations of construction production, to identify the effect of their implementation. In this regard, the problem of forming a parametric model of reengineering of construction technological processes, which involves four enlarged groups of indicators that reflect the quantitative and qualitative characteristics of the processes: materials used, working time, machine time, spatial organization, is considered. It is established that parameters can have either an absolute (physical, cost) or relative (point, percentage) expression and also make their own decomposition. The practical significance of the provisions given in the article is determined by the development of methods of technical rationing, which leads to a reduction in the cost and duration of construction.

This study aims to analyze whether the difference that occurs in the cost of raw materials, direct labor, and factory overhead costs between the standard costs and the actual costs in PLTU LATI is a difference that is favorable or unfavorable. Data collection techniques with field research and library research. The analytical tool used is the analysis of the difference in raw material costs, the difference in direct labor costs and the difference in factory overhead costs. The hypothesis in this study is that the difference allegedly occurs in the cost of raw materials, direct labor costs, and factory overhead costs at PT Indo Pusaka Berau Tanjung Redeb is a favorable difference. The results showed that the difference in the cost of producing MWh electricity at PT Indo Pusaka Berau Tanjung Redeb in 2018, namely the difference in the price of raw material costs Rp. 548,029.80, - is favorable, the difference in quantity of raw materials is Rp. 957,216,602, - is (favorable) , the difference in direct labor costs Rp 2,602,642,084, - is (unfavorable), and the difference in factory overhead costs Rp 8,807,051,422, - is (favorable) This shows that the difference in the overall production cost budget is favorable or profitable. This beneficial difference shows that the company is really able to reduce production costs optimally in 2018.

The Business Cycle

This chapter covers the economic fundamentals of commodity markets (i.e., what shapes the evolution of the price of raw materials) in three steps. First, it covers the theories explaining why the futures curve can be upward or downward sloping, an essential element for commodity producing companies. The evolution of inventories and hedging pressures are the two dominant sources of explanation. Second, the chapter reviews the fundamentals of commodity spot prices: technologies, supply, demand, and speculation. Production costs draw the long-term evolution of prices, but demand and supply shocks can trigger substantial variations in commodity prices. Third, the chapter presents how commodity prices interact with the business cycle. Commodities are influenced by the world activity but can also have a material impact on it.

Shaking Moment

Dynamic balance of the spatial engine is researched. By considering the special wobble-plate engine as the model of spatial RRSSC linkages, design variables on the engine structure are confirmed based on the configuration characters and kinetic analysis of wobble-plate engine. In order to control the vibration of the engine frame and to decrease noise caused by the spatial engine, objective function is choosed as the dimensionless combinations of the various shaking forces and moments, the restriction condition of which presents limiting the percent of shaking moment. Then the optimization design is investigated by the mathematical model for dynamic balance. By use of the optimization design method to a type of wobble-plate engine, the optimization process as an example is demonstrated, it shows that the optimized design method benefits to control vibration and noise on the engines and improve the performance practically and theoretically.
