Task scheduling poses a major challenge for cloud computing environments. ensures cost-effective task execution and improved resource utilization. It is classified as NP-hard problem due to its nondeterministic polynomial time nature. This characteristic motivates researchers employ meta-heuristic algorithms. The number of users capabilities leading increased concerns about energy consumption i...

The task scheduling of real-time tasks request is an important component of survivability system. In survivability system, how to schedule real-time tasks to meet the needs of various services at different levels is one of the important topics in survivability research. A task scheduling algorithm is proposed based on optimization decision theory of variable fuzzy set, which apply optimization ...

scheduling is to determine the priorities or arrange the activities to meet the needs, limitations and certain goals. because the time is always a limited resource, all activities should be scheduled to use optimally and certainly the resource. gravitational force algorithm, like other evolutionary algorithms, is inspired by nature. the effect of the gravity on the objects reciprocally and to a...

Task scheduling is a NP puzzle. Its algorithm is an important research direction. This paper proposes a task scheduling algorithm based on real-coded immune algorithm by studying and analyzing task scheduling models and immune algorithms existed. This paper discusses the coding method, the generation and update of population, the update of memory cells and the values of partial parameters. This...

Cloud computing makes it possible for users to use different applications through the internet without having to install them. Cloud computing is considered to be a novel technology which is aimed at handling and providing online services. For enhancing efficiency in cloud computing, appropriate task scheduling techniques are needed. Due to the limitations and heterogeneity of resources, the is...
