Abstract
Workforce training and operations planning are among the key tactical decisions for maintenance service providers. Insufficient number of certified operators and/or shortage of spare parts lead to the late delivery of repaired devices to the customers. In this paper, an integrated mathematical programming multi-period model is proposed to obtain the optimal procurement, production, inventory, and training plan with the goal of minimizing the total cost of operations, training, and late delivery. We also propose outsourcing and borrowing strategies to mitigate the risk of late delivery in the presence of high demand volumes. The numerical results highlight the effectiveness of integrating workforce training and mitigation strategies in controlling the cost.
