Online scheduling of parallel jobs on two machines is 2-competitive
نویسندگان
چکیده
We consider online scheduling of parallel jobs on parallel machines. For the problem with two machines and the objective of minimizing the makespan, P2|online − list,mj|Cmax, we show that 2 is a lower bound on the competitive ratio of any online algorithm. Thereby we not only improve the existing lower bound of 1 +

Online Scheduling of Jobs for D-benevolent instances On Identical Machines
We consider online scheduling of jobs with specic release time on m identical machines. Each job has a weight and a size; the goal is maximizing total weight of completed jobs. At release time of a job it must immediately be scheduled on a machine or it will be rejected. It is also allowed during execution of a job to preempt it; however, it will be lost and only weight of completed jobs contri...
متن کاملSolving the Problem of Scheduling Unrelated Parallel Machines with Limited Access to Jobs
Nowadays, by successful application of on time production concept in other concepts like production management and storage, the need to complete the processing of jobs in their delivery time is considered a key issue in industrial environments. Unrelated parallel machines scheduling is a general mood of classic problems of parallel machines. In some of the applications of unrelated parallel mac...

متن کاملMulti-Objective Unrelated Parallel Machines Scheduling with Sequence-Dependent Setup Times and Precedence Constraints
This paper presents a novel, multi-objective model of a parallel machines scheduling problem that minimizes the number of tardy jobs and total completion time of all jobs. In this model, machines are considered as unrelated parallel units with different speeds. In addition, there is some precedence, relating the jobs with non-identical due dates and their ready times. Sequence-dependent setup t...
متن کاملOnline Scheduling & Project Scheduling
This thesis presents new and improved scheduling algorithms for a number of scheduling problems. The first part of the thesis deals with two online-list scheduling problems, both with the objective to minimize the makespan. In these problems, the jobs arrive one by one and the decision maker has to irrevocably schedule the arriving job before the next job becomes known. In the second part, a ne...
