Various embodiments described herein relate to a method of predicting article dimensions and controlling release timing of upcoming articles from upstream conveyors and dynamically computing release times for the upstream conveyors. The method includes predicting a dimension of an upcoming article and creating empty spaces on an upstream conveyor between one or more upstream articles from among a set of upstream articles by controlling an operating speed of a set of drive motors of the upstream conveyor based on the predicted dimension for the upcoming article. Further, the release times of the set of upstream articles is dynamically computed based on a cumulative length of the set of upstream articles and an operating speed of the upstream conveyor.
