In order to improve the system resource utilization rate and reduce the response time, a new task scheduling Priority Backfilling First Come First Serve (PB-FCFS) algorithm has been proposed. This algorithm combines backfilling, FCFS scheduling and adopts the dynamic priority strategy in task ...
The effect can be further compounded by other resources dependent on the FCFS scheduled resource. For example, if jobs pile up waiting for CPU service, other resources such as disk drives and I/O devices would go idle. One scheduling algorithm that is not as susceptible to this phenomenon is...

4.2.2. First Come First Service (FCFS) FCFS [32] is one of the simplest task scheduling algorithms. When this algorithm is used for task scheduling, tasks are scheduled based on the order they arrive in the queue, with jobs processing the longest waiting time in the queue being given prio...

MLFQ( Multilevel feedback queue) be one of most potential strategies, for CPU scheduling .It is further extension of multi-level queue scheduling algorithm while multilevel queue scheduling is results of combination of basic scheduling algorithms such as FCFS and RR scheduling algorithm. Therefore, ...
It is the combination of First Come First Served (FCFS) scheduling algorithm and preemption among processes. It is basically used in a time sharing operating system. It switches from one process to another process in a time interval. The time interval or Time Quantum (TQ) is fixed for all ...
scheduling instances are selected from OR-Library to validate its performance. The experimental results show that the proposed algorithm can get the optimal solutions for instances up to 100 aircrafts, and is also capable of obtaining better solutions compared with SS, BA and FCFS for instances up...
Our system is developed under the Intel (R) CORE™i3 micro-portable environment (1.70 GHz CPU, 4 GB RAM) Microsoft Windows 7. We present the experimental results of the NSGAIII algorithm used for scheduling tasks in the cloud. The experiments aim to demonstrate and evaluate the performance ...
