The problem is to find the set of all the Pareto-optimal points, that is, the Pareto frontier, and their corresponding Pareto-optimal schedules. Since the above problem is unary NP-hard, we study the problem under the restriction that the jobs of the first agent have inversely agreeable processing times and weights, that is, the smaller the processing time of a job is, the greater its weight is. For this restricted problem, which is NP-hard, we present a pseudo-polynomial-time algorithm to find the Pareto frontier. We also show that, for various special versions, the time complexity of solving the problem can be further reduced. | Keywords: | Scheduling Three-agent Pareto-optimization Total weighted completion time Total weighted late work Weighted number of tardy jobs |
