Setting the optimal type of equipment to be adopted and the optimal time to replace it

The mathematical models of equipment’s wear and tear, and replacement theory aim at deciding on the purchase selection of a certain equipment type, the optimal exploitation time of the equipment, the time and ways to replace or repair it, or to ensure its spare parts, the equipment’s performance in the technical progress context, the opportunities to modernize it etc.Equipment, optimal type, optimal time

Modul de determinare a costului unitar de producţie pentru metrul cub de masă lemnoasă pe picior

The development of any forestry activity calls the attention on the need to determine in advance productive consumption, costs evolution and to compare them with the level already established by the Forestry Administration according to which they plan wood mass public sales (for forestries in the system)as well as with the level achieved by private forestries which have already become a strong competitor on the market. We may also mention the need to supervise effectively the expenses, to know their volume and structure, to determine as soon as possible the deviations from the established level and the causes which have lead to such deviations, and to identify the place where they occur. In this way we may speak about the need to reconsider the management accounting methods and costs calculation as a main factor for an efficient organization of the economic activity, which should be able to provide adequate information for an efficient management of the forestry activities in a market economy. In the present market economy, forestry managers should be concerned with costs reduction, having in view the interdependence and inverse proportionality that exist between products costs obtained and the profit, as an essential objective of any entrepreneur. They have in view obtaining the smallest cost or one as small as that of competitive units, avoiding unjustified deviations and losses and finally achieving a maximum profit, either by a high price that can assure other services, or by a small profit and a high volume of sales, that is a quick rotation of production factors – product – consumption recovery – plus value.secondary wood mass products, wood species, unit cost, equivalent unit cost

On financial derivatives and differential equations used in their assessment

This paper deals with the assessment of options on dividend paying stock and futures options. We start from the case of the underlying asset who does not generate dividend and then switch to an underlying asset which pays a continuous dividend yield. The final conditions and the boundary conditions added to a partial differential equation, allow an accurate determination of the solution.differential equation, options on dividend paying stock, futures options, Black_Scholes’ model, Black’s model

Romania's public debts and their consequences upon the economy

In June 2009, Romania’s public debts rose by 12.6% more than late last year, that is up to 123.61 billion Lei (29.4 billion Euros), meaning 23.27% of the gross domestic product originally estimated for this year. Foreign loans are not a new phenomenon. Yet, in the current economic context, it is the consequences which might occur that bother most of us as a result of the (significant) increase of public debts. Concluding a loan agreement with the International Monetary Fund is « necessary evil » because it has both advantages and disadvantages. This paper aims at analyzing aspects regarding the benefits, direct and indirect costs, and social effects of such a loan.public debts, elbows, benefits, economy

Reoptimizations in linear programming

Replacing a real process which we are concerned in with other more convenient for the study is called modeling. After the replacement, the model is analyzed and the results we get are expanded on that process. Mathematical models being more abstract, they are also more general and so, more important. Mathematical programming is known as analysis of various concepts of economic activities with the help of mathematical modelsReoptimization, linear programming, mathematical model

Traditional methods versus modern methods of determining unitary cost in forestry

Top level management has in view costs minimizing, so profit maximizing, so that costs adjustment seems to be a vital necessity when the activity developed within the company does not assure the maintenance and stability of the necessary relation between consuming factors and costs. In such circumstances, approaching differing sides of the production cost and improving the methods of calculation has much significance in determining the most appropriate measures necessary for its adjustment and for profit increasing. The whole informational process of costs – formation, control and analysis of costs – involves a careful use the methodological concepts known under the name of classical methods and modern or complementary methods, as well as of other proceedings. Such methods and proceedings cannot be applied separately, only conjugated and integrated in a unitary methodological system, each of these methods and proceedings participating at achieving one or more objectives. Only by their unitary action they can fulfill all the system objectives.Cost, economic efficiency, decisions substantiation, traditional and modern methods for costs determining
