Purpose - Demand for spare parts arises whenever a component fails or requires replacement. The demand patterns for these items are different from those associated with a ‘typical’ Stock Keeping Unit (SKU). Consequently, logistical priorities and decision making processes for the supporting supply chains are also perceived as idiosyncratic in nature. Arguably, a plethora of ‘hard’ methodologies have been put forward in order to manage the relevant inventories. Nevertheless, the level of complexity necessitates a more holistic and multi-disciplinary approach that may also capture contextual information. Such an approach has not been fully elaborated in the academic literature yet and that constitutes the main objective of our work. In this paper we will substantiate the need for additional research in this area pointing out the emerging avenues for further scholarly contributions.
Design/methodology/approach – The supply chain is viewed from a spare part consumer as well as from a providers perspective. Key to our discussion is an accurate description of the maintenance demand pattern known at the consumer’s side as a valuable information source for the entire supply chain.
Findings – Solving the spare parts supply chain puzzle exceeds the realms of single scientific discipline, and involves hard and soft sciences. Besides extending on the quantitative modelling aspects of maintenance demand patterns, soft modelling and analysis is needed to define cooperative settings in which the supply chain parties can operate effectively.
Originality/value – This research is unique in the sense that it provides a most accurate characterization of maintenance demand patterns based on the proven maintenance concept design theory, and that in its arguments, the supply chain problem is used in a realistic context throughout the discussion, with an open and broad mindset rather then from a single hard science perspective.
