“…An operational state refers to the level of activity within a structure. Operational states are commonly described in simple terms of binary ON and OFF values (Wasson, 2006). Whereas, an operational mode specifies an abstract user-selectable set of system activities that focuses on satisfying an objective.…”

Smart retrofitting in maintenance: a systematic literature review

2022

View full text Add to dashboard Cite

The last decade saw the rise of digitalization and data-supported decision making in the manufacturing industry: the Fourth Industrial Revolution. This trend, also known as Industry 4.0, allows manufacturing enterprises to discover manufacturing uncertainties and measure their real manufacturing capability. One of the ways in which Industry 4.0 trends have been exploited is in the improvement of maintenance, which went from following planning-focused paradigms to more proactive-focused stances. Enabling the Industry 4.0 vision for maintenance purposes has historically required companies to either replace or upgrade their existing legacy devices. It is through the latter course of action that Smart retrofitting in maintenance (SRM) intends to bring value to enterprises. This work aims to present a systematic literature review on SRM, utilizing the oft-cited PRISMA methodology. Through this analysis, a definition of SRM that reflects the current state of the art is proposed. Furthermore, the research in SRM applied in the context of different maintenance strategies is assessed (i.e. reactive, planned, proactive and strategic maintenance), and the most common drivers and challenges in SRM are presented. Finally, a roadmap for the implementation of SRM is proposed. The analysis of the SRM literature reveals that there are important research opportunities in the exploitation of SRM for strategic maintenance and asset management. The authors hope that this document leads to the consolidation of a new research area that aims to add value to maintenance in enterprises through the application of smart retrofitting in preexisting legacy devices.

“…Whereas, an operational mode specifies an abstract user-selectable set of system activities that focuses on satisfying an objective. They are not limited to ON / OFF values, since operational modes might also include modes like initialization, calibration, configuration, cleaning, production, and even maintenance (Wasson, 2006).…”

“…Rather than concentrate on mathematical and technical formalism-which can be found, if necessary, in specialist texts on systems theory (Bertalanffy 1968;Boulding 1956, Klir 1969Casti 1985;Skyttner 2005), systems science (László 1983, Sandquist 1985Klir 1991), systems analysis and design (Wasson 2006;Gopal 2002), control theory and cybernetics (Ashby 1957;Wiener 1961;Johnson et al 1963;Leigh 2004), and other fields-Senge wished to codify a way of thinking about dynamics and complexity-that is, a systems thinking-that presents an effective approach for observing and modeling reality, forcing the observer to search for the circular connections, the loops among the interrelated variables of which reality is composed. More than a technique, systems thinking is thus a mental disposition (Anderson and Johnson 1997, p. 20), an attitude, a language, and a paradigm.…”

“…Traditionally, the design of interfaces has focused on the physical and functional aspect of the interface. 6 SOS interfaces have an additional role: they create the "why" of the SOS. They serve as conduits by which value is exchanged between stakeholders and, thereby synergistic relationships are formed.…”

The presence of space situational awareness is one approach to mitigating the long-term risks associated with space debris in low Earth orbit (LEO). As the U.S. and other nations continue to develop the space situational awareness mission area, questions arise as to how stakeholders should act to mitigate the effects of resident space objects and how our understanding of the physics of LEO inform the evolution of ground-and space-based sensors. To characterize interactions among international stakeholders, space situational awareness is modeled as a system of systems with technical and social elements. Through the use of game-theoretic cooperation archetypes and System Dynamics modeling, possible futures are explored. Extensions in space situational awareness capabilities are modeled as mechanisms to improve satellite survivability. Finally, general implications for system architecture and systems of systems are elucidated.
