PACT: Policy Across Composable Timing Rules with a Certified Reward for Flexible Job-Shop Scheduling

PACT is part of the production scheduling work for PPVC module factories: deep reinforcement learning, graph neural network and multi-agent methods for flexible job-shop scheduling that respect time lags, machine setups, availability windows and shared transport, and that use optimality bounds in reward design and credit assignment.
