Abstract
We consider the single-machine preemptive Pareto-scheduling problem with two competing agents A and B, where agent A wants to minimize the number of its jobs (the A-jobs) that is tardy, while agent B wants to minimize the total late work of its jobs (the B-jobs). We provide an $$O(nn_{A}\log n_{A}+n_B\log n_B)$$ -time algorithm that generates all the Pareto-optimal points, where $$n_A$$ is the number of the A-jobs, $$n_B$$ is the number of the B-jobs, and $$n=n_A+n_B$$ .
