Abstract

When handling the problem of selection of investments in industrial equipment, the analysis of one of the components of payment currents, wear and tear, acquires a special interest. And this is so, because operation and efficiency in economic terms depend, to a large degree, on the physical condition in which the investment object is at any given moment.

    With the object of ensuring the opinions in a better way, in the case where 5 hundredths were obtained the tenth has been chosen which gives a greater extension to the interval (greater uncertainty) although with this the upper extreme of the mathematical probability which will be obtained will be somewhat larger than the number strictly corresponding to it.Google Scholar

    Since no <<non linear> > operators have been used in the process, the result should be the same as that obtained through the means, but the simplifications used and the rounding up which was necessary to keep us within the hendecadarian system, have given rise to certain differences.Google Scholar
