FAQ
What is the open shop scheduling problem?
OSSP involves assigning multiple jobs to multiple machines in manufacturing or service settings, where each job can be processed by any machine in any order—a computationally complex optimization challenge.
Why use Transformers for scheduling?
Transformers excel at learning complex patterns and dependencies, allowing them to capture job-machine relationships more effectively than classical methods while scaling better to larger problem instances.
