An algorithm for multi-agent scheduling to minimize the makespan on m parallel machines
Journal of Scheduling(2017)
摘要
This paper considers a multi-agent scheduling problem, in which each agent has a set of non-preemptive jobs, and jobs of all agents are to be processed on m identical parallel machines. The objective is to find a schedule to minimize the makespan of each agent. For an agent, the definition of α point is introduced, based on which an approximation algorithm is proposed for the problem. In the obtained schedule, the agent with the i th smallest α point value is the i th completed agent, and the agent’s completion time is at most i+ ( 1/3-1/3m) times its minimum makespan. Finally, we show the performance analysis is tight.
