What is Scheduler

Handbook of Research on Advancements in Robotics and Mechatronics
A method that arranges task or operations into an appropriate sequence to perform multitasking given access to the system resources. The scheduler also must ensure that processes can meet deadlines.

Abstract
A highly concurrent task-planner for distributed multi-robot systems in dynamical industrial feed-lines is presented in this chapter. The system deals with two main issues: a) a path-planning model and b) a robotic-tasks scheduler. A set of kinematic control laws based on directional derivatives model the dynamical robots interaction. Distributed wheeled mobile robots perform the execution of autonomous tasks concurrently and synchronized just in time. A planner model for distributed tasks to autonomously reconfigure and synchronize online change priority missions by the robotic primitives—sense, plan, and act—are proposed. The robotic tasks concern carry-and-fetch to different goals, and dispatching materials. Numerical simulation of mathematical formulation and real experiments illustrate the parallel computing capability and the distributed robot's behavior. Results depict robots dealing with highly concurrent tasks and dynamical events through a parallel scheme.

Temporalities for Workflow Management Systems
A software module which sorts activities and prepares them for execution according to several criteria, such as the required skill the executor must own, the priority of the activity, the time that activity has already been waiting for to be executed.
