Abstract

A task to be performed using an industrial vehicle is defined and segmented into segments including a start segment and an end segment. The performance of the industrial vehicle while the industrial vehicle performs the segments is measured, and a target score for the task based on an extrinsic factor that is in effect at least one time during performance of the task is defined. The measured performance of the industrial vehicle during the segments is aggregated to create a task performance score, which is evaluated to the target score to create a task evaluation.
