As the product and after-sales service are increasingly integrated, maintenance programs are transitioning from material-based contract to performance-based contract. This paradigm shift enables the equipment manufacturer (i.e. vender) to maximize the service profit post the product installation, while the customer can lower the asset ownership cost with assured operational availability. A main challenge in designing and executing a performance-based maintenance contract has to do with the so-called moral hazard in which one player is more likely to take risks because the resulting costs are borne by the other. Under the principal-agent gaming framework, we propose a multi-criteria contracting model to maximize the utilities of all the stakeholders. The goals are achieved by optimizing maintenance interval, the spare stock level, and the repair capacity. For this non-cooperative game, we prove that the actions of both players can be deduced by each other despite asymmetric information. Hence a first-best solution is guaranteed without moral hazard issue. Numerical studies from wind turbine industry show that a consolidated multi-item contract could be advantageous over multiple single-item contracts as it ensures a higher profit margin at a lower customer’s cost. If time is available, research advances in smart grids, distributed energy generation planning, and zero-carbon supply chain models will be elaborated as well.
