Obsolescence, as a phenomenon affecting both customers and suppliers, as well as end consumers, has always existed, but until about ten years ago, it remained little perceptible to the general public . Not all industrial sectors have the same knowledge or awareness of the impact of obsolescence and scarcity on product flow management or corporate cash flow, for example.

Obsolescence was initially widely studied by manufacturers in sectors such as aeronautics and space. But the "recent" penetration of new technologies (software and products) in sectors such as automotive or home automation is creating real commercial, technical and scientific challenges. Obsolescence can have consequences for the environment, society, product requirements (maintainability, testability, supportability...) and even the way companies operate, in terms of the obsolescence of their production tools. To reduce these impacts, obsolescence must be managed effectively. The management of equipment obsolescence is an important parameter for the profitability of industrial companies, enabling them to mitigate the various risks it may entail. The most common form of obsolescence management is reactive, because it's easier to implement. However, it is sometimes recommended to use it only if the cost associated with the obsolescence of a component is low . If the probability of obsolescence and the associated costs are high, proactive methods are recommended . This article focuses on proactive obsolescence management, and more specifically...
