with additional maintenance costs will be charged. For example, the surpluses in the warm-up phase, since these so called by early failures, such as assembly, manufacturing or material defects, etc. free budget worksheetsīased 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. 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. The following linear injury until damage to the so-called boundary is determined by the maintenance and repair activities are strongly influenced.įorecast of economic life based on parametersįor the prediction of the useful life can be, for example, the net present value method used. At the end of this phase of life is the engine in optimum condition. 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". 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. 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. The computed service life, the economic life depends, is in the depreciation rates calculated as depreciation into account. It can therefore be shorter than the economic and technical life. 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.). The technical lifetime of a plant is generally based on a specification or specifications, or based on past experience. The economic life of an aggregate is reached when the capitalized income from the operation of the facility related costs. Regarding the lifetime of a plant is initially between economic, technical, technological, technical and tax-calculation service life can be distinguished: 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. In the context of investment decisions is the determination of the useful life of an installation to the most important tasks. Life of the plant influenced investment decision
