The article is devoted to the development of improved information and analytical support for the design of several options for production processes in the food industry, which are implemented both with the same and with different options for a set of technologically specialized structural units of the enterprise. When choosing the option of safe-oriented development of the production system, the criteria of minimum financial costs, minimum time costs, maximum load of structural units were used. To solve the problems of forming a virtual safe-oriented development of production systems at enterprises that are part of a network organizational form, an algorithm for evaluating potential partners based on an analogue of a multifactor matrix model is presented. First, each potential partner is assessed according to the characteristics of technological compliance and production capacity. At the next stage, each potential partner is assessed according to the characteristics of the current load and production capacity, and then according to the characteristics of the technological level and production potential. For a comprehensive assessment of each technology partner, the position in the matrices of correspondence, load, efficiency is determined and belongs to one of the selected ten groups. This approach makes it possible to select and propose the main and additional performers for additional investments in the safe development of production systems and the implementation of unique production operations or events. This approach also makes it possible to carry out a sustainable, safe development of production systems in the food industry in crisis conditions of the economy from a scientifically grounded standpoint.

The paper presents the task scheduling issue, which main aim is to establish a proper sequence of tasks, that would maximize the utilization of companys production capacity. According to the literature sources, the presented sequencing problem, denoted as CSP (Car Sequencing Problem) belongs to the NP-hard class, as has been proven by simple reduction from Hamiltonians Path problem. Optimal method of solution has not yet been found, only approximate solutions have been offered, especially from the range of evolutionary algorithms. Regardless of specific production system, while considering reception of new tasks into the system, current review of the state of the system is required in order to decide whether and when a new order can be accepted for execution. In this paper, the problem of task scheduling is limited to the specific existing mixed-model production system. The main goal is to determine the effective method of creation of task sequence. Through the use of computational algorithms, and automatic analysis of the resulting sequence, rates of production are able to be checked in a real time, and so improvements can be proposed and implemented.

The aim of the study was to examine the changes in production and export of raspberries and sour cherries, which are the domain of Polish production on the international markets, in the countries of Eastern and Southern Europe during the 2006-2017. There was used data from Faostat database for the analysis of fruit production, and from Comtrade database for the analysis of export volume. Study points to the development of production and an increase in the export of raspberries in countries with a smaller area of cultivation of this fruit crops and stability in countries with a large area of crops of raspberries. In the case of sour cherries, in most countries, both large and small area plantings, production potential, and volume of production of fruit of this species declined. The export of sour cherries increased particularly from countries with less potential in the production of sour cherries. The development of the production and export of raspberries from countries with lower production capacity may in the future be competition for Poland on the international markets.

The Impact

The article is devoted to the study of Ukraine’s European integration course, a complex and multilevel process. It is established that the vector of European integration provides Ukraine with ample opportunities to attract foreign investment and new technologies, increase the technological level of production and increase the competitiveness of domestic producers in the domestic market, the EU market and world markets. It is established that most domestic enterprises are acutely short of qualified labor resources, innovation is absent or at a low level and is financed only by own funds of enterprises, there is no possibility to attract available financial resources, and all this complicates modernization of production facilities and bringing Ukrainian producers to compliance with European market standards. The article analyzes the change in the volume of export-import operations, profitability, and development of capital investments and innovation of domestic enterprises. It was found that the dynamics and volume of capital investment have positive trends, but a comparative analysis of the dynamics of growth of profitability and capitalization of production capacity found that in the latter Ukrainian enterprises are highly dependent on borrowed capital, due to significant limitations of their own reserves. In the current conditions of economic European integration, Ukrainian enterprises face a number of barriers that prevent them from fully entering and operating effectively in the European market. At the state level, it is political and economic instability, imperfection of the legislative field, high cost of credit resources, which leads to low innovation potential, shortage of qualified personnel and funds for modernization of existing assets and technological renewal. The strategic task of Ukraine should be the state policy aimed at supporting domestic enterprises and increasing their competitiveness in the form of comprehensive measures aimed at providing available credit resources for domestic producers, development of their innovative activity, promotion of the transfer of new technologies, which in turn will be to promote the technological level of Ukrainian enterprises and increase the level of competitiveness of goods and world markets.

Elastic Characteristics

Gelling carrageenans are polysaccharides extracted from the Gigartinales order of red algae. These are additives used essentially in the food industry for texturizing, stabilizing or gelling various formulations. Although a consensual gel mechanism has been reached which encompasses a coil-to-helix transition followed by the self-assembling of helices in a network, the structure–elastic relationships in the network are still to be clearly established. This paper reviews the reports in which carrageenan gel structures have been systematically compared with gel elastic properties. The focus is on the sizes documented for structural units, such as strands, aggregates, voids or network meshes, as well as on the reported linear and nonlinear elastic characteristics. The insufficient rationalization of carrageenan gel elasticity by models which take on board mechanically relevant structural features is underlined. After introducing selected linear and nonlinear elastic models, preliminary results comparing such models to structural and rheological data are presented. In particular, the concentration scaling of the strain hardening exhibited by two types of carrageenan gels is discussed.

Crisis Conditions

One of the important and urgent tasks of microeconomics is the problems of research of the economic system, in which there are restrictions associated with the planned volume of output or the size of the enterprise production capacity. These constraints are set by the requirement that the analyzed trajectories do not leave some given region of the control existence space. Most often, such restrictions for all time points are set in the form of inequalities, and certain requirements are imposed on the function of the phase coordinates of the object, their value at a given time. This problem is classified as an optimal control problem with mixed and phase constraints. In general, this area is of scientific interest and requires consideration. In this case, we study the microeconomic model of the household economy as the most stable object in the conditions of crises. The accumulated savings are subject to a natural phase constraint of non-negativity. This led to the study of the features of the microeconomic formulation of the problem of finding a method for the optimal division of material resources into consumed and accumulated parts, since the imposition of a natural phase restriction on the non-negativity of accumulated savings makes everything much more complicated. Just as in macroeconomics, consumption is optimized, but not in its pure form, but the integral discounted utility of consumption is maximized. The relation equation in this paper differs from a similar macroeconomic equation, since the household exists and survives in crisis conditions in a different way than do social organisms and large enterprises. That is why the article formulates and proves sufficient conditions for solving the problem with a phase constraint.

Abstract It is an honour and a pleasure to wish to all actors of the ASME Journal of Nuclear Engineering and Radiation Science (Chair, Editors, Authors, Readers, and Reviewers) my New Year's greetings. This 2022 year must be seen towards an exit of the COVID-19 pandemic situation, looking for better perspectives. We must capitalize on the best of this period and on the way out of the health crisis. Even in this extremely difficult context, the links still existed. They were even been strengthened by showing more solidarity, support and mutual aid. We must keep these qualities within our scientific community, because we must now face a new decisive challenge: responding to a very strong increase in carbon-free energy demand. In order to meet this challenge, nuclear energy has a major role to play among all other non-CO2 emitting sources of energy. Its great flexibility and massive production capacity makes it a perfect complement to renewable production systems.

Companies must respond quickly to customer needs and ensure the desired quality and low price in order to remain competitive in a market. It becomes necessary to create new concepts of production systems that meet all requirements imposed by consumers. The increase of reliability of machines and equipment, staff competence and forecasting a size and subject of demand increase the ability to react quickly to changes in the business environment. Therefore, the objective of this paper is to estimate the agility characteristics of a company (size of demand, interarrival time of orders and reliability of machines) and to verify its production capacity and rapid response capabilities. The characteristics are estimated for three variants of the production system: self-operating company, companies operating in cooperation, company buying additional machine.

The Impact

Abstract Consumer interest in the source of their food, its environmental footprint, and the impact of diet on health has supported the growth of the grass-finished beef (GFB) industry. Studies have concluded that GFB has distinct nutritional differences from conventionally-finished beef. As the GFB industry continues to expand, it is vital to continue to explore the nutritional complexities and variation in the product. To achieve this, a survey of grass-finishing production systems throughout the United States was conducted, and beef finished on the participating farms was analyzed for its nutritional composition, including fatty acid (FA), mineral and fat-soluble vitamin contents. Samples were analyzed from 12 producers and annual production capacity of farms ranged from 25 to 5,000 cattle, with a mean age of cattle at harvest of 26.8 ± 2.30 mo. An array of finishing diets included grazing exclusively in perennial pasture, incorporating annual forage crops, and feeding a variety of harvested forages with supplementation of non-starch feed byproducts. Beef muscle tissue FA content was analyzed by gas chromatography-mass spectrometry (GC–MS). The mean ratio of omega-6 (n-6) to omega-3 (n-3) FA in samples varied significantly by producer, ranging from 1.80 to 28.3 (P < 0.0001), with an overall sample set median of 4.10. A selection of minerals including iron, magnesium, and potassium were analyzed by ICP emission spectroscopy and mineral content significantly differed by producer for all minerals (P < 0.001). Mean α-tocopherol and β-carotene content was 610.6 μg/100 g beef and 32.2 μg/100 g, respectively. The amount of these antioxidants also varied between producers (P < 0.0001), but tended to be greater in beef finished solely on fresh forages. This survey indicates that commercially available GFB can vary in nutritional composition due to the diverse practices used to grass-finish cattle.

Calculation Algorithm

This paper proposes a calculation algorithm that creates operational points and evaluates the performance of distribution lines after reinforcement. The operational points of the line are probabilistically determined using Monte Carlo simulation for several objective functions for a given line. It is assumed that minimum voltage at all nodes has to be balanced to the maximum load served under variable distributed generation production, and to the energy produced from the intermittent renewables. The calculated maximum load, which is higher than the current load, is expected to cover the expected needs for electric vehicles charging. Following the proposed operational patterns, it is possible to have always maximum line capacity. This method is able to offer several benefits. It facilitates of network planning and the estimation of network robustness. It can be used as a tool for network planners, operators and large users. It applies to any type of network including radial and meshed.

Goat Farming

Goat farming is a very important activity contributing to the social and economic development of northeastern (NE) Brazil. The objective of the present study was to characterize the goat farming production system in five of the nine states that constitute the Brazilian NE (Ceará, Paraíba, Piauí, Rio Grande do Norte, and Sergipe). Research was carried out in 230 rural properties located in 62 municipalities of the NE of Brazil, in regions exhibiting a productive arrangement and significant goat population density. An epidemiological questionnaire seeking information on economic, productive, and social aspects of owners/properties was supplied to all properties. The results described the goat farming system in the Brazilian NE as family and subsistence, directed towards domestic consumption and local commerce, and exhibiting a low technological level. The farmers' education level, investments, and technical assistance were all considered low, and thus insufficient or inadequate for a full development of the activity in the region. Therefore, such aspects are suggested to be taken into account in the planning of future goat farming development policies—particularly financing and technical assistance, better preparation of farmers, administrative aspects, forage production and conservation, and the implementation of actions towards reproductive and frequent disease control.
