Method and system for scheduling execution of activities

摘要

A method ( 300 ) and system for scheduling execution of activities, such as jobs of a batch processing. An estimated duration of each job is predicted ( 365-367 ) as a running average of the measured durations of completed instances of the job executed previously. The method of the invention uses historical data to identify ( 375-385 ) repeatable patterns for the job duration; for example, a decision tree is inducted using the completed instances of the job as training examples. The decision tree is applied for classifying ( 325 ) each new instance of the job to be executed, according to its planned time of execution; the estimated duration of the job is revised ( 330 ) using an adjustment factor associated with the class assigned to the new instance of the job.
