Gestão do ciclo de vida: aplicação na MB: A gestão da obsolescência dos sistemas de defesa (sd) empregada nas fragatas classes "Tamandaré" durante as fases de operação e apoio do ciclo de vida

Abstract

Military innovations have long driven the creation of new products, which, over time, are made available to society. Understanding the concept of the Life Cycle of Defense Systems and its phases, for the readiness and availability of naval resources, allows for a better understanding of the factors that affect the operations for which the Naval Power is capable. However, with technological advances taking place at the speed of Moore's law, an important issue arises for defense defense managers, obsolescence. Studies on obsolescence management began in the late 20th century, coinciding with the advent of the end of the Cold War and a transformation of the electronics industry to manufacture equipment and systems with shorter product life cycles. In this way, the need to understand that obsolescence is inevitable and cannot be prevented is identified and is recognized as one of the most critical challenges for the Armed Forces and the industries that make up the Defense Industrial Base, which need to maintain these Systems for long decades. The lack of planning drives the adoption of reactive measures for the treatment of obsolescence, which often entail high costs. It is important to establish institutional policies and measures to manage the means considering the management of their obsolescence. Assessing the situation, possible causes and limitations of models and methods of identification, treatment and control of obsolescence applied to Defense Systems make up the strategic framework for the actions necessary to deal with this phenomenon. Thus, for the Navy, Obsolescence Management (GO) of naval resources and sensors, weapons, propulsion and self-protection systems becomes very relevant. Even when considering the Strategic Program for the construction of the "Tamandaré" Class Frigates, this problem is quite evident, being, at the same time, an opportunity for the Naval Force to include the "good practices of management of obsolescence", internationally consecrated in this context . The purpose of obsolescence management is to ensure that obsolescence is managed as an integral part of design, development, production, and maintenance in order to minimize cost and detrimental impact throughout the product's Lifecycle, as long as organizations consider this as a factor of strategic importance. Once the relevance of the impacts that obsolescence can cause, in particular to naval Defense Systems, is highlighted, and considering the scope of the theme "Life Cycle Management (LCV) - Applied to MB", this work proposes to verify whether the documents structuring agents, necessary for the formulation of the strategy for the LCM of Defense Systems in the MB, conducted by the Marine Material Sector, establish the strategic directions for the GO of these systems.
