Abstract The objective of this study was to realize the economic deterministic analysis of steers production system in full cycle, finished in feedlot or cultivated pasture at twenty-four months old, utilizing or not the quality bonus from slaughterhouses. The study was realized using data from meta-analytic survey of studies in the central region of Rio Grande do Sul state, Brazil, in Microsoft Excel® spreadsheets. The systems were simulated considering the male and female calves weaned early, at the tree months of age, and finished at the 24 months of age in feedlot or cultivated pasture. After the slaughter, it was realized the economic deterministic analysis. According to financial return indicators net present value (NPV), benefit:cost index (IB:C) and additional return on investment (ROI) only the system in pasture show return at the end of planning horizon, and the internal return rate (IRR), modified internal return rate (MIRR) and discounted payback (PBd), show that this system possesses a higher risk of investment. The feedlot system show negative results as a investment project. The bigger cost center was depreciation, feeding supply and taxes, and the quality bonus shows up an interesting alternative of return, but was not sufficient to render the feedlot system a viable project.

O objetivo deste trabalho foi analisar a viabilidade econômica da produção de carvão vegetal em dois sistemas produtivos: oito fornos de superfície acoplados a uma fornalha para queima de gases e dez fornos do tipo “rabo-quente” sem sistema de queima de gases. Para análise econômica, definiu-se uma produção anual média igual a 1.571 metros cúbicos de carvão (mdc) e horizonte de planejamento de 12 anos, sendo propostos 2 cenários. No primeiro cenário, após a colheita da madeira, realiza-se o plantio de uma nova floresta, permanecendo o custo da madeira constante em todo o planejamento; no segundo cenário, após a colheita, considerou-se a condução da brotação, reduzindo os custos na 2ª rotação e consequentemente os custos da madeira. A análise econômica foi realizada através da determinação dos seguintes indicadores: Valor Presente Líquido (VPL), Valor Anual Equivalente (VAE), Razão Benefício/Custo (B/C) e Lucratividade. Os indicadores calculados demonstraram a viabilidade dos dois sistemas produtivos avaliados em ambos os cenários propostos, porém o sistema fornos-fornalha apresentou melhores valores para os indicadores. Conclui-se que a produção de carvão vegetal nos sistemas avaliados foram viáveis economicamente, com o sistema fornos-fornalha gerando maior lucro ao produtor de carvão.Palavras-chave: Fornos de alvenaria; análise determinística; valor presente líquido. Abstract Economic viability of charcoal production in two production systems. The objective of this study was to analyze the economic viability of charcoal production in two conversion technologies: eight surface kilns coupled to a furnace for burning gases (kilns-furnace system) and ten "rabo-quente" or traditional charcoal kilns without burning gases system. An average annual production of 1571 cubic meters of charcoal (mdc) was used to perform the economic analysis. A planning horizon of 12 years and two scenarios were proposed. In the first scenario, after harvesting the wood, the planting of a new forest was performed, and the cost of wood remained constant throughout the planning horizon. In the second scenario, after the harvest, the conduction of shooting was considered, which reduced costs in the second rotation and consequently the cost of wood. The economic analysis was performed by determining the following indicators: Net Present Value (NPV), Equivalent Annual Value (EAV) and Benefit - Cost Reason (B/C). Calculated indicators demonstrated the viability of producing charcoal in the two production systems in both scenarios proposed, but kilns-furnace system presented better values. As conclusion, production of charcoal in the evaluated systems were economically viable. Kilns-furnace system was able to generate more profit to charcoal producer.Keywords: Kilns; deterministic analysis; net present value.

The Impact

Economic evaluations were carried out on stochastically simulated production systems using data from a grazing systems’ trial, which evaluated the impact of resting (i.e., grazing cessation) alfalfa (Medicago sativa L.) – bromegrass (Bromus riparius Rehm. ‘Fleet’) and grass-only (G) pastures during the critical prefrost period on beef cattle (Bos taurus) productivity. Grazing systems were compared on the basis of calculated net present value of returns analysis. Lower production costs through reduced fertilization requirements resulted in alfalfa–grass (AG) preference over G pastures, while returns from increased calf sale weights resulted in nonrested systems being preferred over rested systems. However, low presence of alfalfa in the AG pastures likely limited the potential for resting pastures to improve production through increased alfalfa persistence. This evaluation found nonrested grazing of AG pastures to be preferred over other treatments on the basis of increased returns and reduced risk.

Economic Potential

Over the past five years, in the country and in the world there has been an increase in the production and consumption of non-alcoholic tonic drinks (NTD). Representatives of various scientific schools are developing new NTD formulations. The regional characteristics of the used plant raw materials with a tonic effect are taken into account. The priority task of the food industry is to carry out activities aimed at making healthy food products, taking into account not only the traditions and habits of the population, but also the cost-effectiveness of introducing them into production. The paper considers the requirements of regulatory documentation for raw materials, elaborates the technological scheme of NTD production, describes the requirements for labeling and packaging of the finished drink. Introducing new technologies into production is an expensive process. The aim of the work is a preliminary automated assessment of the economic efficiency of an investment project for the production of NTD based on new recipes. The specified assessment is carried out from the point of view of traditional indicators of project efficiency, using the Karma optimization software package, which allows identifying the economic potential and finding the optimal characteristics of investment, production, financial activities of investment and production projects. The influence of the key indicator of the project (the market price of a unit of production) on the main indicators of the effectiveness of the investment project is studied. The life cycle is analyzed and the economic potential of the investment project is revealed through the use of an optimization mathematical model. The dependence of the net present value of the project on the planning horizon is described with a variation in the market unit price parameter. High characteristics of the economic efficiency of the investment project are obtained. Practical recommendations are given on sales markets, production technology, implementation of investment projects related to the production of NTD «Wild Cat».

Surgical residents cite “increased income potential” as a motivation for pursuing fellowship training, despite little evidence supporting this perception. Thus, our goal is to quantify the financial impact of surgical fellowship training on financial career value. By using Medical Group Management Association and Association of American Medical Colleges physician income data, and accounting for resident salary, student debt, a progressive tax structure, and forgone wages associated with prolonged training, we generated a net present value (NPV) for both generalist and subspecialist surgeons. By comparing generalist and subspecialist career values, we determined that cardiovascular (ANPV = $698,931), pediatric ($430,964), thoracic ($239,189), bariatric ($166,493), vascular ($96,071), and transplant ($46,669) fellowships improve career value. Alternatively, trauma (-$11,374), colorectal (-$44,622), surgical oncology (-$203,021), and breast surgery (-$326,465) fellowships all reduce career value. In orthopedic surgery, spine ($505,198), trauma ($123,250), hip and joint ($60,372), and sport medicine ($56,167) fellowships improve career value, whereas shoulder and elbow (-$4,539), foot and ankle (-$173,766), hand (-$366,300), and pediatric (-$489,683) fellowships reduce career NPV. In obstetrics and gynecology, reproductive endocrinology ($352,854), and maternal and fetal medicine ($322,511) fellowships improve career value, whereas gynecology oncology (-$28,101) and urogynecology (-$206,171) fellowships reduce career value. These data indicate that the financial return of fellowship is highly variable.

Using Data

Data Envelopment Analysis (DEA) is an established powerful mathematical programming technique, which has been employed quite extensively for assessing the efficiency/performance of various physical or virtual and simple or complex production systems, as well as of consumer and industrial products and technologies. The purpose of the present study is to investigate whether DEA may be employed for evaluating the technical efficiency/performance of 3D printers, an advanced manufacturing technology of increasing importance for the manufacturing sector. For this purpose, a representative sample of 3D printers based on Fused Deposition Modeling technology is examined. The technical factors/parameters of 3D printers, which are incorporated in the DEA, are investigated and discussed in detail. DEA evaluation results compare favorably with relevant benchmarks from experts, indicating that the suggested DEA technique in conjunction with technical and expert evaluation could be employed for evaluating the performance of a highly technological system, such as the 3D printer.

AbstractSocietal concern with the welfare of egg laying hens housed in conventional cages is fostering a transition towards cage-free systems in many countries. However, although cage-free facilities enable hens to move freely and express natural behaviours, concerns have also been raised over the possibility that cage-free flocks experience higher mortality, potentially compromising some aspects of their welfare. To investigate this possibility, we conducted a large meta-analysis of laying hen mortality in conventional cages, furnished cages and cage-free aviaries using data from 6040 commercial flocks and 176 million hens from 16 countries. We show that except for conventional cages, mortality gradually drops as experience with each system builds up: since 2000, each year of experience with cage-free aviaries was associated with a 0.35–0.65% average drop in cumulative mortality, with no differences in mortality between caged and cage-free systems in more recent years. As management knowledge evolves and genetics are optimized, new producers transitioning to cage-free housing may experience even faster rates of decline. Our results speak against the notion that mortality is inherently higher in cage-free production and illustrate the importance of considering the degree of maturity of production systems in any investigations of farm animal health, behaviour and welfare.

Additional Information

Cerrado vegetation is Brazil's second largest biome, comprising about 388 municipalities in Minas Gerais state alone and serving as an important source of natural resources. A large share of the wood charcoal produced in Minas Gerais is sourced from Cerrado vegetation. The objective of this work is to assess the economic viability of Cerrado vegetation management for wood charcoal production, under conditions of risk. The study site is a fragment of Cerrado subjected to five levels of intervention as to basal area removal. For risk analysis, the Monte Carlo method was applied, using charcoal price, interest rate and land value as input variables, and using Net Present Value as output variable over an infinite planning horizon. It was concluded that introducing risk in the economic analysis of the various Cerrado management regimes helped provide additional information to that obtained by deterministic analysis, improving understanding and ensuring safety in decision-making about the economic viability of such regimes. For all treatments, the probability of VPL being negative increases with increasing cutting cycle lengths. For all treatments, the optimal cutting cycle is ten years. Treatments where a larger volume of wood was removed proved less prone to risks of economic inviability since they secure more revenue than treatments where less wood was removed.

This paper considers what animal welfare is and the importance of animal welfare to the consumer. It also considers how different production systems are perceived in terms of kindness to animals, and outlines a method of assessing the costs of animal welfare by analysing the costs of intensive egg and broiler production and comparing them with costs of free-range production by using data from the UK. The extra costs associated with free-range production are due to higher labour, feed, building and equipment costs.

Investment Projects

The scenario of global competitiveness demands more and more of the organizations the search for continuous improvement. For survival, in the face of adverse market conditions, modern production management strategies are essential to make production processes increasingly efficient, lean and sustainable, minimizing losses in their production systems. In this sense, when thinking about changes in production lines, in search of improvements in their process, criteria that provide Benefits, Opportunities, Costs and Risks (BOCR) should be considered. In this way, managers and executives should rely on tools and methods that allow them to guide their decisions in a clear way. The objective of this work is to apply a method of Decision Making with Multiple Criteria to the alternatives of investment projects in production lines in Lean Manufacturing concept. As a general result, it was possible to observe the applicability of the AHP BOCR method for the decision-making case involving several criteria and subcriteria for choosing the Lean investment project in the steel environment, the preferred alternative being the discontinuity of the production line 1 and the absorption of their respective production volume by production lines 2 and 3 through investments in them.

Execution Times

This paper focuses on how computer execution times and net present value (NPV) are affected by different groupings of tree-selection harvest controls, different procedures to determine harvest timing, and tree data aggregation. The problems related to stand management are viewed as a hierarchy, where the main problem is determining harvest periods and the subordinate problem is determining what trees to cut in a given set of harvest periods. The solution technique is a derivative-free search process, and the objective is to maximize the NPV of harvest revenues for a stand over a given planning horizon. The tree-selection harvest controls are based on diameter and species groupings. The procedure to determine harvest timing is based on Tabu search and fixed cutting cycles, respectively. Sensitivity analysis is performed for a selection of stands in southern Sweden, where each stand is represented by a set of inventoried plots. Both even-aged and uneven-aged management are considered. Solutions improved with the number of decision variables. The Tabu search procedure proved very efficient at determining harvest periods for the even-aged problems. For the uneven-aged problems, fixed cutting cycles approximated the harvest timing problem, but at considerably shorter execution times. It is suggested that aggregated data be used for determining harvest timing, after which, using the original nonaggregated data, the tree-selection problem for a given set of harvest periods can be resolved.
