Moderate Scale

In the Shaanxi province, small and scattered plots impede an increase in the efficiency of apple production. Developing a moderate operation scale is a proper tool to solve inefficiencies in apple production, as it enables improving the factor allocation efficiency, resulting in higher yields, higher profit, or lower production costs. However, the moderate operation scales, based on output, profit, and production costs, may be different. This paper aimed to evaluate the moderate operation scale of apples from three perspectives of increasing yields and profits and reducing unit production cost. The study was based on survey data collected from 661 randomly selected apple farmers in eight counties of the Shaanxi province, China. The collected data were analyzed quantitatively by the input-output model, the net profit model, and unit production cost model. The findings show that: (1) The moderate operation scale oriented to increasing apple yields in the Shaanxi province should be 0.87–1.53 ha. (2) The moderate operation scale oriented to increasing the net profit of farmers in the Shaanxi province should be over 1.53 ha. (3) The moderate operation scale oriented to reducing the unit cost of apple production in the Shaanxi province should be 0.20–0.53 ha. The study provides evidence that policymakers should grasp the balance point and find the intersection of the operation scale based on output, profit, and unit production cost when guiding apple growers to carry out the moderate scale. We propose that 0.87–1.53 ha may be a suitable operation scale for apple production in the Shaanxi province at the current stage.

The Cost

Renewable liquid biofuels for transportation have recently attracted enormous global attention due to their potential to provide a sustainable alternative to fossil fuels. In recent years, the attention has shifted from first-generation bioethanol to the production of higher molecular weight alcohols, such as biobutanol, from cellulosic feedstocks. The economic feasibility of such processes depends on several parameters such as the cost of raw materials, the fermentation performance and the energy demand for the pretreatment of biomass and downstream processing. In this work, two conceptual process scenarios for isobutanol production, one with and one without integrated product removal from the fermentor by vacuum stripping, were developed and evaluated using SuperPro Designer®. In agreement with previous publications, it was concluded that the fermentation titer is a crucial parameter for the economic competitiveness of the process as it is closely related to the energy requirements for product purification. In the first scenario where the product titer was 22 g/L, the energy demand for downstream processing was 15.8 MJ/L isobutanol and the unit production cost of isobutanol was $2.24/L. The integrated product removal by vacuum stripping implemented in the second scenario was assumed to improve the isobutanol titer to 50 g/L. In this case, the energy demand for the product removal (electricity) and downstream processing were 1.8 MJ/L isobutanol and 10 MJ/L isobutanol, respectively, and the unit production cost was reduced to $1.42/L. The uncertainty associated with the choice of modeling and economic parameters was investigated by Monte Carlo simulation sensitivity analysis.

Este trabalho teve o objetivo de analisar a estrutura de custos de madeira serrada de Pinus taeda com duas metodologias de desdobro, denominadas de sistema convencional e sistema otimizado. Os diâmetros das toras variaram de 18 a 44 cm. Foram testadas 100 toras, sendo 50 toras divididas em cinco classes diamétricas para cada sistema de desdobro. Utilizando o sistema convencional de desdobro, verificou-se que os custos fixos representaram 12,03% do custo unitário de produção. Desses, os gastos com salários e encargos sociais foram os mais significativos, representando 9,22% do custo total unitário de produção, e por 76,61% dos custos fixos. O custo variável representou 87,97% do custo total unitário de produção, sendo que 84,64% foram relativos a aquisição de toras. Utilizando o sistema programado de desdobro das toras, a participação percentual do custo fixo aumentou para 14,87%, decorrente da queda ocorrida nos custos variáveis. A participação do custo variável unitário representou 85,13% do total dos custos unitários, apresentando uma redução de 3,23% em relação ao desdobro convencional. Com o desdobro programado, a redução no custo total foi de 5,12%.Palavras-chave: Pinus; classificação de toras; modelos de corte; otimização. AbstractIncome analysis costs in Pinus taeda sawn wood using two methodologies. This study aimed to examine the cost structure of Pinus taeda sawn wood using two methodologies of log sawing, called conventional and optimized systems. The logs diameter ranged from 18 to 44 cm. A total of 100 logs were tested, being 50 logs divided into five diameter classes for each sawing system tested. Using the conventional sawing method, the fixed costs accounted for 12.03% of the unit production cost. From these, wages and social charges accounted for 9.22% of the total unit production cost, and for 76.61% of the fixed costs. The variable cost represented 87.97% of the total unit production cost, and the logs acquisition accounted for 84.64% of the variable cost. Using the optimized sawing system, the percentage of fixed cost increased to 14.87%, due to the decrease in the variable costs. The participation of variable cost unit accounted for 85.13% of total the unit costs, showing a reduction of 3.23%, compared to the conventional sawing method. The reduction in the total cost using the optimized sawing method was 5.12%.Keywords: Pine; logs classification; sawn models; optimization.

The Cost

This paper analyzes a simple transfer-pricing policy based on the actual cost of production. I show that the performance of actual cost-based transfer pricing can be improved by using an additive markup above the unit production cost. I also show that this additive policy dominates an entire class of alternative markup policies, including the more common multiplicative policy, in which the transfer price is set at the actual cost plus a percentage markup. The optimal additive markup is shown to increase with increasing prices for the firm's product, and decrease with the cost of the supplying division's investment.
