Gestão proativa de obsolescência: uma abordagem capaz de estender o ciclo de vida de sistemas complexos em operação

Abstract

Obsolescence has become a major problem in the industry since rapid technological developments began to appear. In addition, the scarcity of raw materials and improvements in environmental and safety legislation are increasing the scale of the problem.

This paper then addresses a proactive obsolescence management methodology for Complex Product Systems (CoPS) in operation, capable of prioritizing and monitoring the entire structure of a product, in addition to offering palliative proposals for the solution of the problem. The entire project is based on the Diminishing Manufacturing Sources and Material Shortages (DMSMS) standards, created by United States Department of Defense (USDOD).

The method of prioritization, monitoring and palliative solutions were developed based on existing standards and literature and also on the experience of many engineers responsible for the obsolescence management at all levels of business: supplier, assembler and customer.
