Article: A systems approach to managing complex engineering assets: exploring shifts in equipment management and reliability enhancement paradigms Journal: International Journal of Agile Systems and Management (IJASM) 2022 Vol.15 No.1 pp.93 - 117 Abstract: Engineering asset management is a complex socio-technical system, and there has been a surge in efforts to optimise the capacity utilisation of these assets in the wake of conflicting economic and performance objectives. The major challenge is in determining which assortment of approaches (tools, strategies, techniques, methodologies and philosophies) to apply in order to get optimal trade-offs of cost, risk and performance or reliability. This paper critically reviews the literature to examine shifts in physical asset management paradigms over the past few decades and to determine the best combination of approaches; and it shows that none of these approaches are able, individually, to optimise the trade-offs, but as a cluster. It proposes a Systems-thinking model-based integration approach. Pilot studies have shown that using the model proposed can yield savings in maintenance costs of 15-40% and in avoided costs of up to 15%.

Abstract: Engineering asset management is a complex socio-technical system, and there has been a surge in efforts to optimise the capacity utilisation of these assets in the wake of conflicting economic and performance objectives. The major challenge is in determining which assortment of approaches (tools, strategies, techniques, methodologies and philosophies) to apply in order to get optimal trade-offs of cost, risk and performance or reliability. This paper critically reviews the literature to examine shifts in physical asset management paradigms over the past few decades and to determine the best combination of approaches; and it shows that none of these approaches are able, individually, to optimise the trade-offs, but as a cluster. It proposes a Systems-thinking model-based integration approach. Pilot studies have shown that using the model proposed can yield savings in maintenance costs of 15-40% and in avoided costs of up to 15%.
