A significant part of industrial systems have requirements on long life times. Such requirements on the complete system impose requirements on its corresponding embedded systems to be operational for an equally long time. As a consequence it is of paramount importance to be able to replace obsolete components of the embedded systems during the life time of the system, and to be able to update part...
Handling of obsolete software and/or hardware components together with management of function updates in a complex embedded system with an expected life time of more than 30 years can be a very difficult to almost impossible task. This types of challenges can be found in a large number of companies in, for example, the power transmission industry, power plants, aviation etc. In this paper we present...
Management of obsolete software- and hardware-components along with the addition of new components and functionalities in existing embedded systems can be a very difficult or almost impossible task. If there at the same time is a requirement put on the system that it should be in operation for more than 30 years, then the evolution of the embedded system architecture over such a long duration of time...
