Chapter 6 - Analyses of an innovative approach: Mitigation of Obsolescence Cost Analysis (MOCA).

6.3 Logical flow to the base of the MOCA6.

The analysis realized from tool the MOCA comes lead through the shown steps and the logical flow in the successive figure.


Figure 6.3: Logical flow second which the MOCA is structured tool.

In order to understand effectively better like tool the work, it will be better to analyze in the detail the several one step. We suppose of having to preview the date of obsolescence of a logic divice, for which the primary attribute8 is represented from the logic family of belongings. The forecast the cycles of life of the members pertaining to the device class of the member leave considering of which we want the obsolescence date and that they introduce various values of the primary attribute. In the successive figure, for example of this, the cycles of life of some logic families subdivided in various are shown the typical ones are made.


Figure 6.4: Cycles of life of some logic families.

Leaving from these data, diagrammano the dates of introduction and phase-out according to the date in which the sale peak has been taken place; such points come then interpolated with two straight ones of which are gained, then, the expression analytics. The result that is obtained is brought back in the following image.


Figure 6.5: Dates of introduction and phase-out according to the year of the peak of sale for some logic families.

The given presumed one of obsolescence for the member who goes itself to replace is given from the following expression:


In which the terms they have meant following: In the example L =. Tool Price H/HL comes used is in the appraisal of the single plans of design refresh, is in the final esteem of the life cycle cost of the system once that the final plan of design has been chosen refresh.
