Abstract This article proposes a method to support decision making from a cost management perspective in the initial stage of production planning. In a research analyzed the problem of selecting production resources for order realization. The research was based on computer simulation. The developed model focuses on the planning of the production process in the event that the products have not yet been produced and it is necessary to decide where to produce it (with what production resources) so that the total production costs are as low as possible. In this concept, the FlexSim simulation environment with a built-in optimization module was used to solve the problem. The basic steps of simulation model built were discussed, taking into account the necessary information and input data. The results show the impact of the application of selected simulation scenarios on the level of use of production resources, due to the minimization of the total production costs and the duration time of the production process.

Исследования по определению энергетической эффективности пастбищных систем со злаковыми и бобово-злаковыми травостоями проведены в Федеральном научном центре кормопроизводства и агроэкологии им. В. Р. Вильямса. В статье приведены результаты агроэнергетической оценки многовариантных пастбищных систем со злаковыми травостоями, созданными в 1946 году. Даны количественные показатели по сбору обменной энергии, совокупным затратам на её производство, окупаемости затрат в зависимости от системы ведения пастбищ. Изучена эффективность совокупных затрат в виде овеществлённого труда (на семена, удобрения, сельскохозяйственные машины, средства огораживания загонов и прочее) и живого труда (работы трактористов, пастухов и строителей и др.). Обоснована высокая агроэнергетическая эффективность изучаемых пастбищных систем благодаря мобилизации в продукционный процесс природных факторов, долевое участие которых в структуре производства обменной энергии составило 69–84%. Природные факторы, участвующие в продукционном процессе луговых агроэкосистем, характеризуются большим разнообразием. Это не только использование солнечной энергии и азотфиксация бобовыми травами, но и долголетие травостоев, самовозобновление фитоценозов, дерновообразовательный процесс (повышение плодородия почвы), получение дешёвого корма и улучшение здоровья животных при летнем выпасе. Роль возобновляемых природных факторов выявлена на основе балансового метода, принятого в экономике (по разнице сбора обменной энергии и антропогенных затрат). Благодаря ведущей роли природных факторов в структуре произведённой продукции агроэнергетический коэффициент окупаемости совокупных затрат антропогенной энергии (АК) за счёт сбора обменной энергии достигал 3–6 раз в среднем за 45 лет. Разработанные в результате долголетних исследований многовариантные энергосберегающие пастбищные системы обосновывают возможность рекомендовать их производству с учётом применения различного уровня энергозатрат. Ключевые слова: культурные пастбища, системы ведения, долголетние травостои, сбор обменной энергии, совокупные антропогенные затраты, окупаемость затрат. The investigation was conducted at the Federal Williams Research Center of Fodder Production and Agroecology and was aimed at testing energy efficiency of gramineous and legume-gramineous swards. This article presents the results obtained on pasture ecosystems with gramineous planted in 1946. Exchange energy yield, total production costs and economic effectiveness were analyzed. Total production costs comprised costs for seeds, fertilizers, machinery, construction materials, labor, etc. Introduction of natural factors into the production process resulted in higher energy efficiency. Their share amounted to 69–84% in the final exchange energy yield. There are a lot of natural factors that affect grass productivity such as solar energy, nitrogen-fixation, sward longevity and regeneration, soil fertility, low-cost feed production, and livestock health. The value of natural factors was determined according to the balance method (by the difference between exchange energy yield and anthropogenic costs). Since environmental factors had a leading role in the production process, the return rate raised by 3–6 times for 45 years due to exchange energy increase. Therefore, pasture ecosystems developed can be recommended for a large-scale forage production.

Theory Of Constraint

Constraints are activities that prevent companies from carrying out production activities. Along with the increasingly competitive world economy today, industrial companies are required to be more sensitive in anticipating constraints that occur both internally and externally. These constraints must be considered by the company because it can hamper the production process which has an impact on production costs as well as sales volumes which ultimately cause losses to the company. One tool that can identify constraints of a company is the Constraint Theory. This study aims to find out what constraints occur in the production process and the impact of these constraints on production costs. The method used in this study is descriptive. The results of this study are internal constraints are engine damage and external constraints are delays in the delivery of raw materials. The impact of these constraints on production costs is the loss of raw material costs and an increase in factory overhead costs.Keywords: Constraints, Production Cost, Theory of Constraint

ABSTRACTLowering the pH in bacterium-based succinate fermentation is considered a feasible approach to reduce total production costs. Newly isolatedEnterobacter aerogenesstrain AJ110637, a rapid carbon source assimilator under weakly acidic (pH 5.0) conditions, was selected as a platform for succinate production. Our previous work showed that the ΔadhE/PCK strain, developed from AJ110637 with inactivated ethanol dehydrogenase and introducedActinobacillus succinogenesphosphoenolpyruvate carboxykinase (PCK), generated succinate as a major product of anaerobic mixed-acid fermentation from glucose under weakly acidic conditions (pH <6.2). To further improve the production of succinate by the ΔadhE/PCK strain, metabolically engineered strains were designed based on the elimination of pathways that produced undesirable products and the introduction of two carboxylation pathways from phosphoenolpyruvate and pyruvate to oxaloacetate. The highest production of succinate was observed with strain ES04/PCK+PYC, which had inactivated ethanol, lactate, acetate, and 2,3-butanediol pathways and coexpressed PCK andCorynebacterium glutamicumpyruvate carboxylase (PYC). This strain produced succinate from glucose with over 70% yield (gram per gram) without any measurable formation of ethanol, lactate, or 2,3-butanediol under weakly acidic conditions. The impact of lowering the pH from 7.0 to 5.5 on succinate production in this strain was evaluated under pH-controlled batch culture conditions and showed that the lower pH decreased the succinate titer but increased its yield. These findings can be applied to identify additional engineering targets to increase succinate production.

Final Consumer

GDP is considered as a critical infrastructure that characterizes the global interaction of consumers and manufacturers of the final product in the national economy. For the analysis and modelling of GDP, the Leontiev model is used to analyze and to model GDP as a critical infrastructure, where costs are interpreted in two ways - as consumer spending and as producer costs. This allows you to determine the degree of their influence on each other through the established production structure. Based on Leontiev's aggregated three-sector model, two scenarios were modelled: a) the impact of final consumer spending on output and the formation of added value and b) the impact of changes in added value on output and final consumer spending. The model includes three sectors – the agricultural sector, industry and service sectors. In the first scenario, the increase in the final consumed product in the agricultural sector by 1000 yen causes an increase in output in the agricultural sector by 1153.5 yen, in industry by 594.4 yen and in the service sector by 358.1 yen. At the same time, total production costs will increase by 1106.0 yen; added value will increase in the agricultural sector by 549.8 yen, in industry – 216.8 yen, in the service sector – 233.4 yen. The volume of production growth can be determined only through the Leontiev model. In the second scenario, an increase in added value in the agricultural sector by 1000 yen brings about an increase in output in the agricultural sector by 1153.5 yen, in industry by 1470.4 yen and in the service sector by 480.7 yen. For both scenarios, the assessment and verification of calculations of GDP growth and output are carried out by the balance method – output and GDP growth is described within the Leontiev model. The three-sectoral model is useful for educational purposes, scientific research; to reach the method in a specific example. The approach can be extended to models of greater dimension and large size.

Purpose: The purpose of this paper is to elaborate guidelines regarding geometric configurations of a nozzle manifold that have an impact on the effectiveness of the quenching process and occurrence of quenching distortions. Design/methodology/approach: Within the framework of this study there an optimisation of nozzle manifold geometry was carried out with the help of numerical simulations created using Ansys CFX software. In the first stage, a simplification of the nozzle-sample system reduced to a two-dimensional simulation was employed to determine the most optimal location of the coolant stream. In the second stage, several arrangements of nozzle manifolds were tested in a three-dimensional simulation. The parameters that were taken into account included the rate of sample cooling, the uniformity of cooling with a sample volume and heat coefficient takeover read from its surface. Findings: The different active/inactive nozzle arrangements within the manifold and the impact of the specific arrangements on the uniformity of heat transfer from the sample surface were compared. Research limitations/implications: The simulations carried out within the framework of this study are one of the elaboration stages of a new flow heat treatment technology. Practical implications: The application of an efficient cooling chamber in flow treatment makes it possible to limit quenching distortions to a minimum. An optimal adjustment of cooling parameters and cooling nozzle configuration to the shape of the element in order to make the cooling uniform translate directly into a reduction in distortions. Avoiding the necessity to reduce distortions after quenching means there is a significant reduction in detail production costs (grinding). Originality/value: The concept of single-piece flow in the heat treatment for the mass industry is developing rapidly and constitutes a fully automated element of a manufacturing line, adjusted for the purposes of being included in the production process automatic control system. It also makes it possible to conduct comprehensive and integration quality supervision and management at the level of an individual element, which is not possible in the case of batch heat treatment, which is a gap in the production process.

The paper aims to determine the impact of direct payments on the production, costs and profitability of individual farms. Our research on individual farms (participating in the EU-FADN) was carried out in Silesian region (for years 2005– –2008). Our studies indicated that the highest total production was achieved on farms in the group with the highest level of direct payments. In the group of the largest farms (in terms of the area) the share of plant production in the structure of total production increased with then rise of direct payments. Direct payments influenced the changes in the direction and structure of agricultural production in the farms. They also stabilized farm incomes in periods of unfavorable economic conditions for agricultural production.

Introduction. The problem of ensuring the economic sustainability of modern hotel and restaurant businesses is due to the need to ensure their sustainable development in a changing external environment, unstable market conditions, increased competition and rising prices for production resources. Advantages in solving these problems provide reduction of production costs, diversification of activities, novelty of products / services, technical and technological updating and improvement of material and technical base, improvement of management system, working conditions and financial condition of the enterprise, which is directly related to the economic efficiency of the business process. Since overall efficiency is the output of the production process and is defined as the ratio of output to cost of operations, and its increase provides an increase in economic effect, the most favourable economic conditions and competitive advantages in the market, the problem of establishing the relationship between efficiency gains and economic sustainability of enterprises is exacerbated. Aim and tasks. The purpose of the study is to analyze and determine the degree of influence of the factors of progressive development on improving the efficiency of use of production resources and ensuring the stability of functioning of the enterprises of the hotel and restaurant business through modeling, calculation of indicators of progressive development. Results. As a socio-economic system, an enterprise is characterized by complex multicomponent relationships between a large number of interdependent and interacting elements of different types, each of which can in turn be represented as a system (subsystem). The criteria of progressive economic development of the hotel and restaurant business enterprises are defined in the paper and the methods of their structural and component analysis are grounded. Models of pairwise regression between costs, types of capital investments and parameters of investment and innovation activity are constructed. The sequence of calculation of indicators of progressive economic development is offered. Conclusions. Increasing the cost of new machinery and equipment, existing buildings and structures, new construction and acquisition of software are contributing to the growth of labor resource potential, reducing material consumption, and increasing the cost of production. On the basis of structural-component analysis regularities of differentiated mutual influence between the indices of production resources consumption and directions of investment-innovative activity are determined, indicators of progressive development are used, by which it becomes possible to measure the level of efficiency of use of resource potentials, economic growth of the enterprises of the hotel and restaurant business.
