N2 - Commercial off-the-shelf (COTS)-centric cyber physical systems often contain software and hardware elements with life-spans shorter than the systems' intended life-span. Various studies have examined hardware obsolescence, although in most systems, software costs contribute as much, or more, to the total life cycle costs than hardware. The aim of our research effort is to explore, synthesize, and compile past research efforts on obsolescence in the context of COTS-based systems, and propose new ways to overcome related issues. This research effort suggests the need for systematic perspectives to streamline potentially overbearing acquisition processes while focusing on core critical aspects affecting systems sustainment and cost. Significant life cycle costs associated with obsolescence mitigation approaches, therefore, programmatic strategic planning should be adapted to include the context of obsolescence with the objective to improve the efficiency of new COTS-intensive CPS systems with enduring perspectives. The study reveals opportunities and challenges for obsolescence in COTS-based CPSs.
