This article discusses the problem about the method for the optimization of cutting parameters. A newly developed computational method which is different from the former was used for the optimization of cutting parameters. This method has its advantages of the controllability of the precision and higher speed when the precision requirement of the system is not very high. It can optimize cutting parameters toward the objectives of maximum production rate, minimum production cost and maximum profit rate.

Optimizing Algorithm

Optimization analysis for maximizing the total profit of an automated assembly system consisting of automated assembly machines and operators was performed. In this analysis, concepts of two kinds of breakdowns, which depend on accuracy of parts and on machine running speed were introduced. Based on basic decision variables—accuracy of parts, machine running speed, and number of operators, profit rate of the automated assembly system was maximized through dynamic programming, and an optimizing algorithm for the maximum profit rate was developed with a numerical example.

R Relation

The well-known w–r relation results from the price equation system and the normalisation equation, that is, the equalisation of price of the normalisation commodity (numéraire) with a positive constant. In this article, we show that the w–r relation is neither that of the given technique nor that of the given production system, but that of the normalisation subsystem, that is, the subsystem which, using the above-mentioned technique, produces the normalisation commodity as its own net product. So, the maximum nominal wage rate, the slope and the maximum profit rate of the w–r relation vary with the normalisation commodity and the above constant. In inference of them, (a) the comparison and the ranking of given techniques concerning our profitability as the choice of the most profitable of them too is in reality a comparison, a ranking and a choice of the corresponding normalisation subsystems; (b) the phenomena of re-switching appear and disappear due to the change of the normalisation commodity; and (c) the comparison, the ranking, the choice of techniques and the ascertainment of the re-switching phenomenon are impossible. Finally, the normalisation subsystem tenders an index magnitude to solving the as yet unsolved problem of how the prices change with income distribution.

This paper presents a study on profit optimization of steel shot blasting systems. In the study, the influences of blasting process parameters including air pressure, nozzle diameter, cost components as well as the effect of the nozzle wear on the profit of a cleaning process were investigated. Based on the results of the optimization problem, a regression model for calculation of the optimum exchanged nozzle diameter in order to get the maximum profit rate was proposed. By using the model, both the profit and the blasting time can be reduced considerably.

Input Combination

The purpose of this study are to (1) determine the combination of inputs used in producing products such as beef sausages and veal sausage meatball; and (2) determine the optimal combination whether the product can provide the maximum profit. In order to determine the combination of inputs and maximum benefits can be used linear programming with graphical and simplex method. The valuation result shows that the optimal input combination would give a profit of Rp. 1.115 million per day.

Profitability of dairy farming in relation to the type of feeding systemWe investigated the profitability of dairy farms in relation to the type of feeding system (seasonal pasture vs. permanent housing). An economic analysis was carried out of data on the structure and financial health of 50 farms in 2007 using questionnaires filled in by the farmers. The Principal Component Analysis (PCA) was applied to reveal causal relationships between a number of characteristics of the farms. The two axis of PCA explained 40.48% and 16.13% of the variability among the selected farm characteristics. Profitability related more to the number of subsidies, the area of arable land, the number of livestock and to the milk and plant production than to the area of meadows and pastures. Although a better cow performance was achieved on farms with confined herds, the profit per agricultural area and profit rate did not differ significantly between the two feeding strategies (P>0.05). The profit was 3,259 and 3,655 CZK/ha on average and the profit rate 7.9% and 5.6% on average on farms with pastured herds and on farms with confined herds, respectively. A lowering of input costs and a more effective utilisation of grasslands may further enhance profitability.
