Book excerpt: In this paper, we study the rescheduling problem of a two-tier supply chain after major supply disruptions. In our model, a service provider provides maintenance job requests to its customers. The replacement parts that are used in the maintenance requests are provided by a designated manufacturer. After major production disruption hits, the service provider needs to reschedule all jobs to minimize related costs. We formulate the job rescheduling problem for a coordinated supply chain as an integer program to minimize the tardiness and the channel's total inventory cost. An extension of the main model with revised processing time is also discussed. A two-stage genetic algorithm is proposed to solve this integer program. We tested this algorithm on a dataset generated from a heavy machinery maintenance provider. Numerical results show that our model generates solutions that outperforms the original schedule. In addition, the proposed algorithm has better performance compared with other common genetic algorithms.
