811 results about "Task completion" patented technology

Task Completion definition: it is a specific condition of a task, which matches certain “completion” criteria that is a special set of characteristics to recognize that a task was successfully accomplished. Usually, a fact that a task was completed is identified by a special research which can be formalized by a procedure.

Task scheduling method under cloud computing environment

The invention discloses a task scheduling method under a cloud computing environment, and belongs to the technical field of computer application. The method of the invention comprises the following steps that: computer nodes register node information from a data center node; the computer nodes transmit health states thereof to a task scheduler through a health state reporting mechanism; the task scheduler allocates tasks to the computer nodes according to the node information, wherein during allocation, the difference between the computer nodes is not considered; computer nodes report the completion of the task to the data center node after each task is completed; the task scheduler allocates a new task to balance the task load between the computer nodes according to the task completion condition of each computer node; the data center node deletes the node information thereof when an abnormal computer node is found, and reallocates the task which is not completed by the node and serves as the new task; and the task scheduler recovers the task which is not completed within a specified time threshold value and reallocates the task as the new task. By the method, the safety for the task allocation under the cloud computing environment can be improved, and the throughput of the task scheduling is effectively improved.

Arrangement for scheduling tasks based on probability of availability of resources at a future point in time

InactiveUS7386850B2High level of serviceImprove customer serviceMultiplex system selection arrangementsDigital computer detailsTask completionComputer science
A resource task-completion forecaster (122) of an ACD (104) determines a probability that an agent (156) will complete servicing a presently-assigned call by a specified time horizon h. The forecaster determines (202) the type of call that the agent is servicing, determines (204) the amount of time t that the agent has already been servicing the call, retrieves (206) the mean and the variance of time historically spent by agents on servicing this type of call to completion, fits (208) the mean and the variance to a lifetime closed-form cumulative-probability distribution F, such as a Weibull distribution, to determine parameters of dispersion and central tendency, evaluates (210, 212) the distribution for t and h+t, computes (216) the probability of the agent not having completed servicing the call by now as Q=1−F(t), and computes (218) the probability that the agent will have completed servicing the call by the time horizon as
P=F(t+h)-F(t)Q.
A resource scheduler (124) sums (302) the probabilities P for all agents to obtain the number of agents that are expected to be available at the time horizon, and schedules (304) for the time horizon no more than that number of new calls for servicing by the agents.

Distributed task scheduling method for unmanned aerial vehicle fleet in dynamic environment

The invention provides a distributed task scheduling method for an unmanned aerial vehicle fleet in a dynamic environment and aims to achieve that the unmanned aerial vehicle fleet get rid of the limits of a ground control station in the dynamic environment and autonomously conduct task scheduling, and the real-time performance of task scheduling is improved. The distributed task scheduling methodis implemented by the steps that a decision-making unmanned aerial vehicle allocates a task to each unmanned aerial vehicle and sends an execution instruction to each unmanned aerial vehicle; all the unmanned aerial vehicle fleet execute the tasks according to the execution instructions sent by the decision-making unmanned aerial vehicle, and communicate with the decision-making unmanned aerialvehicle through a heartbeat mechanism; the decision-making unmanned aerial vehicle conducts optimal scheduling on the tasks of all the unmanned aerial vehicle fleet; the unmanned aerial vehicle fleetexecute the tasks which are determined again according to the flight paths respectively, and formation is kept; the decision-making unmanned aerial vehicle monitors the task completion conditions of all the unmanned aerial vehicle fleet, and when all the tasks are completed, the unmanned aerial vehicle fleet makes a return voyage. By means of the distributed task scheduling method, the unmanned aerial vehicle fleet can select a correct scheduling method according to the change of the dynamic environment, the real-time performance of task scheduling is improved, and the unmanned aerial vehiclefleet can autonomously execute the task.
