Productivity Gains

The state of Pará has the fifth largest cattle herd in Brazil at 20.3 million heads, and beef cattle breeding accounts for 44.32% of the agricultural production value. Using a recursive econometric model estimated by the generalized method of moments, we evaluated the effects of variables that define the supply and demand of slaughtered beef cattle from 1990 to 2015. The results showed that supply and demand were inelastic to prices. Increases in rural salary and calf prices negatively affected supply, and the response to rural credit applications occurred with a four-year lag due to the biological and technological characteristics of production systems. Deforestation tended to increase the supply of cattle and slaughterhouses appropriated the largest share of the economic surplus generated. There were productivity gains since the early 1990s, with the yield of slaughtered animals was 230.55 kg for cattle and 182.25 kg for cows, while currently, it is 276 and 202.5 kg, respectively. The creation of the Agriculture and Livestock Defense Agency of the State of Pará had a positive effect on the supply of cattle and the expansion of agroindustry structure, contributing to the supply of large markets with higher quality beef.

Imperfect Items

Purpose The purpose of this study is to formulate two multi-product single-machine economic production quantity (EPQ) models by considering imperfect products. Two policies are assumed to deal with imperfect products: selling them at discount and applying a reworking process. Design/methodology/approach A screening process is used to identify imperfect items during and after production. Selling the imperfect items at a discount is examined in the first model and the reworking policy in the second model. In both models, demand during the production process is satisfied only by perfect items. Data collected from a case company are used to illustrate the performance of the two models. Moreover, a sensitivity analysis is carried out by varying the most important parameters of the models. Findings The case study in this research is used to demonstrate the applicability of the proposed models, i.e. the EPQ model with salvaging and reworking imperfect items. The models are applied to a high-tech un-plasticized polyvinyl chloride (UPVC) doors and windows manufacturer that produces different types of doors and windows. ROGAWIN Co. is a privately owned company that started in 2001 with fully automatic production lines. Finally, the results of applying the different ways of handling the imperfect items are discussed, along with managerial insights. Originality/value In real-world production systems, manufacturing imperfect products is unavoidable. That is why, it is important to make a proper decision about imperfect products to reduce overall production costs. Recently, applying a reworking strategy has gained the most interest when it comes to handling this problem. The principal idea of this research is to maximize the total profit of manufacturing systems by optimizing the period length under some capacity constraints. The proposed models were applied to a company of manufacturing UPVC doors and windows.

Primary Documents

The article analyzes the process of documenting the costs of enterprises ‘ activities. In the process of activity, enterprises bear a variety of costs in the production of necessary products for the functioning of production and non-production systems in the state, but the continuity of this process depends on the well-coordinated work of the energy complex, since energy consumers are all areas of the state economy that are set when forming GDP. Therefore, the importance of analyzing the composition of costs, production, financial, operational, and other types at energy enterprises is important, and given the gradual growth of the role of energy in the state economy, it is relevant. All expenses that are recorded in the company’s accounting records during the reporting period must be confirmed by documents characteristic of a certain group of expenses, so this particular direction was chosen for the study. The paper examined the existing features of the main primary documents for accounting for payroll accruals and payments, settlements with accountable persons, cash, material, and other expenses. In the process of writing the paper, the principle of filling out and containing 18 current documentary forms of the corresponding direction was described, divided into groups according to their purpose for a more visual display of the results of the study.

Quantifying the range of fertilizer and irrigation application rates applied by the ornamental nursery and greenhouse industry is challenging as a result of the variety of species, production systems, and cultural management techniques that are used. To gain a better understanding of nutrient and water use by the ornamental industry in Maryland, 491 potential operations (including multiple addresses and contacts) in the state were mailed a packet of information asking for their voluntary participation. Of the 491 potential operations, it was determined that 348 operations were currently in operation. Of those 348 operations, 48 (14% of the operations in the state) participated in a site visit and an in-depth interview, and a detailed site analysis of the water and nutrient management practices was performed on a production management unit (MU) basis. The authors define an MU as a group of plants that is managed similarly, particularly in regard to nutrient and irrigation application. Greenhouse operations reported, on average, 198, 122, and 196 kg/ha/year of nitrogen (N), phosphorus (P, as P2O5), and potassium (K, as K2O) fertilizer used, respectively, for 27 operations, representing 188 MUs. Twenty-seven outdoor container nursery operations had a total of 162 MUs, with an average of 964, 390, and 556 kg/ha/year of N, P2O5, and K2O fertilizer used, respectively. Field nursery (soil-based) operations were represented by 17 operations, producing 96 MUs, with an average of 67, 20, and 25 kg/ha/year of N, P2O5, and K2O fertilizer used, respectively. Irrigation volume per application was greatest in container nursery operations, followed by greenhouse and field nursery operations. Data were also analyzed by creating quartiles, which represent the median of the lowest 25%, the middle 50%, and highest 75% of values. It is likely that the greatest quartile application rates reported by growers could be substantially reduced with little to no effect on plant production time or quality. These data also provide baseline information to determine changes in fertilization practices over time. They were also used as inputs for water and nutrient management models developed as part of this study. These data may also be useful for informing nutrient application rates used in the Chesapeake Bay nutrient modeling process.
