Advancing stock policy on repairable, intermittently-demanded service parts.

Many firms generate revenue by operating systems or fleets, such as rental cars, aircraft, equipment etc. The contribution of service parts to the availability of the system or fleet is well documented. The majority of service parts are intermittently demanded. Research on intermittent demand has primarily focused on forecast accuracy and generally does not distinguish between the stock policies of consumable versus repairable parts, although repair is sometimes more cost-effective. But managing repairable parts is considerably more complex than managing consumable parts.

In this paper, the authors employ a new approach to advance the supply chain manager’s ability to determine cost-effective stock. They use a multi-objective approach, covering waiting times and various components of cost. They solve this using different approaches, including seeking a Pareto surface.

They test the new approach via a case study and show the approach to be beneficial for a given firm The approach is generalisable to many sectors, including transport, health and local services. This paper offers a significant development of stock modelling.
