Maintenance Scheduling Problem with Fuzzy Random Time Windows on a Single Machine

This work developed an integrated scheduling model which incorporated both production scheduling and maintenance planning for a single machine problem and considered the multiple objectives of minimizing total weighted completion time and maximizing average timeliness level under a fuzzy environment. First, a fuzzy random variable for maintenance time windows was considered, and this model was then transformed using the expected value. Finally, a numerical example was used to demonstrate the value of this improved algorithm, the computational results from which proved its efficiency.
