Chapter 3 - the problem obsolescences.

Like pointed out in chapter previous, one of the problems to face, like contractor of a contract CLS, is that relative one to the management of the obsolescences that unavoidablly will be introduced during the period of validity of the agreement trade them: such phenomenon, in fact, can create serious problems of availability in the phase of support of electronic equipment, above all, when draft of complex systems as in the event of radar or weapon systems in general terms.
The obsolescence of the members, from how much emerges during the last few years from practical ascertainments, in fact, it is becoming one of the greater ones cost driver in the support of equipment and arranges electronic complexes produced in limited number: such systems, just because of their complexity and of the times elevates you of acquisition, introduce a life cycle the much longest one of the members in contained they.
Moreover, just for such motivations, the problem of the obsolescence, is seen like one of the greatest supporters than risk for the technological impact on the availability and manutenibilità of systems of the cited type over.
The risk financial, than, as it is understood, anch'esso is unavoidablly associated to such problematic, can better be understood through the following affirmations:

The nature, causes and the management of the obsolescence of the members have not been neither considered, neither understood in full load, are in the private industry that in that one of the weapon systems, until little years, until has ago not been understood that phenomena of this type often happened toppo and cost too much for being only ignore to you or to be resolved with a reactive approach through analogous actions to those brought back in the previous affirmations.

3.1 Introduction

The problem of the obsolescence can invest whichever equipment or product, above all if much complex, in all is made of its cycle of life; it is not problematic regarding exclusively a single type of item, but it can regard hardware, software, tools, equipments of support or test....For this reason, the management of the obsolescences (Obsolescence Management OM) would not have absolutely to be ignored neither during the phase of planning and development of a system (Acquisition Phase), neither during the phase of use (Utilization Phase).
As it is easy to intuire, the relative problems you to the obsolescence, above all have a stricter impact on those systems that introduce a life cycle a lot along, if this last inglobano component with cycles of life remarkablly short.
Exactly this the case of the radars, as also of all the paramilitary weapon systems and.
In the literature developed in military atmospheres and paramilitary Americans, where the problem has seen engages to you program managers, logisticians and item during the last few years managers, the obsolescence comes commonly indicated with acronym DMSMS (Diminishing Manufacturing Sources and Material Shortage) and, in the Department of Defense Material Management Regulation 4140.1-R, it comes defined like:
''The loss of, or the impending loss of, the last known supplier of an item or raw materials. DMSMS occurs when manufacturers of items or raw material suppliers batch processing lines production two to reasons such as rapid change in item or material technology, uneconomical production requirements, foreign sources competition, Federal environmental or safety requirements, or limited availability of items and raw materials used in the manufacturing process”. (Cfr. Appendix To pag. 154).
In other words, an obsolescence problem is introduced when an item or a member more available because more is not produced from the last Notes supplier or original equipment manufacturer (the OEM).
The reasons for which such phenomenon verification is numerous and different and, in some productive atmospheres, as those paramilitary soldiers and, many of they, fuse the own roots in historical events that have changed the productive political.
