The useful life of the assets identified
Life of the plant influenced investment decision
In the context of investment decisions is the determination of the useful life of an installation to the most important tasks.
The determination of the useful life of a plant is one of the main areas in the context of a procurement decision of fixed assets can be managed.
Regarding the lifetime of a plant is initially between economic, technical, technological, technical and tax-calculation service life can be distinguished:
The economic life of an aggregate is reached when the capitalized income from the operation of the facility related costs.
The technical lifetime of a plant is generally based on a specification or specifications, or based on past experience.
The technological life is temporally dependent on the constantly-evolving technology and the resulting customer needs (for example, semiconductor technology, quality, increased labor costs, new products, etc.). It can therefore be shorter than the economic and technical life.
The computed service life, the economic life depends, is in the depreciation rates calculated as depreciation into account.
The view from the tax resulting useful life differs from that calculated in relation to the length of the amortization period, and be applied shall be the value.
Analysis of the wear pattern
In determining the useful life is to be noted that the wear and tear or injury during a stressed component of a machine is never constant, because the boundary conditions such as load changes, start-up and discharge processes, etc. constantly changing.
The wear course is particularly in the so-called warm-up phase of a part is relatively high, because the surface roughness produced "rub" and Fits "restore". At the end of this phase of life is the engine in optimum condition.
The following linear injury until damage to the so-called boundary is determined by the maintenance and repair activities are strongly influenced.
Forecast of economic life based on parameters
For the prediction of the useful life can be, for example, the net present value method used. This investment calculation method allows a consideration in relation to the "Life-cycle costs." Be taken into account besides the technical costs (maintenance costs, production-related costs) and economic characteristics such as cost, residual income, inflation or interest rates. free budget worksheets
Based on the fact that the surpluses are not paying in every period of life are constant, but dynamic with the phases of plant life correlate, for the various phases of life factors into account. For example, the surpluses in the warm-up phase, since these so called by early failures, such as assembly, manufacturing or material defects, etc. with additional maintenance costs will be charged.
The normal operation phase of life
Surpluses may also deposit in the so-called normal operation phase of life in each period is not a maximum, since by chance failures such as error handling, dirt particles or maintenance errors increased payout amounts are necessary. Finally, in the last phase of the life cycle of a plant, the possibility that the surpluses through wear or fatigue negative personal finance software.
In order to determine the useful life, it is particularly important to the capital value of the plant investment is already beginning to establish. This corresponds to the capital value is not the volume of investment, but a value, the possibility of a series of investment realized. Thus, the variables

the net present value formula. The inputs and disbursements are in the different periods of life is not viewed as a constant. Therefore, the useful life of less operating time periods in which the plant was already operating. An early retirement of the plant is only from the sensible payback time, because the capital value of the investment volume.
Influence of Anlagenausmusterung to life
The question concerning the recovery and disposal of production is closely related to the determination of economically optimal use. Is the end of an economic life of a plant is reached, it goes under the Anlagenausmusterung particular personal finance budgeting
the minimum cost design and implementation of a disposal facility or transfer to another production process,
the successful sale of the optimal location or legacy
the minimal loss of plant removal (decommissioning grants).
It differs in this respect between the scheduled and unscheduled Scrapping. The latter is determined by the decision because of market-or operational circumstances at the time required in the planning was not considered and therefore a revision of the total or of one or more operational plans for the partial result.
For the company arise regarding asset recovery and disposal of various alternatives in terms of their target effects. Monetarily detectable quantities, in education and deposits respectively in costs (Ausmusterungskosten, cost recovery, re-use costs) and revenues (Ausmusterungserlöse, re-use proceeds) show. personal budget worksheet
On the other hand can be indirect effects such as improvements in quality by a facility renewal is difficult to determine, since new investments with the old and the quality increase due to a possible major overhaul to be compared. home budget software
Basically, however, is an extension of the useful life as long as advantageous as possible because of extra-border payment surpluses are positive.
