This study analyzes the correlation between the obsolescence of citations and access concerning a broad range of subjects, including fields that have not been dealt with in previous studies, shedding light on the differences between these two types of obsolescence and the characteristics for each field. The analysis investigates approximately 1,200 journals that were randomly sampled from 11 su...

Design refreshes and various reactive mitigation solutions are used to manage technology obsolescence (DMSMS) in systems. Design refreshing solely to manage obsolescence is, however, not practical for many systems, and therefore, obsolescence management refresh activities need to be coordinated with technology insertion roadmaps. This report describes the development of an information model tha...

This paper develops the idea that obsolescence acts as an incentive device to provide quality for experience goods. The argument is that obsolescence affects the frequency at which consumers repurchase products and may punish producers for a lack of quality. A higher rate of obsolescence enables a firm to convince its consumers that it provides high quality. We identify a trade–off between qual...

Many technologies have life cycles that are shorter than the life cycle of the product they are in. Life cycle mismatches caused by the obsolescence of technology (and particularly the obsolescence of electronic parts) results in high sustainment costs for long field life systems, e.g., avionics and military systems. This paper describes a new methodology for forecasting electronic part obsoles...

Rapid changes in technology have led to an increasingly fast pace of product introductions. New components offering added functionality, improved performance and quality are routinely available to a growing number of industry sectors (e.g., electronics, automotive, and defense industries). For long-life systems such as planes, ships, nuclear power plants, and more, these rapid changes help sust...

Obsolescence of human skills impacts the support of long field life systems. Human skills obsolescence is a growing problem for organizations as they try to estimate and mitigate the effects of an aging workforce with specialized (and possibly irreplaceable) skill sets. Difficulties with skills obsolescence have been reported in a number of industries including industrial controls, aerospace, a...

The aerospace and defence industries are moving towards new types of agreement such as availability contracts based on Product-Service System (PSS) business models. Obsolescence has become one of the main problems that will impact on many areas of the system during its life cycle. This paper presents the major challenges to managing obsolescence for availability contracts, identified by means o...
