Abstract

A computer-implemented method for determining that a worksite machine requires refuelling is described. The method involves accessing incident message information and known worksite information; processing the incident message and known worksite information to generate state information; processing the state and known worksite information to generate situation information; and processing the situation and known worksite information to determine that the worksite machine has insufficient fuel to complete the tasks currently assigned to the worksite machine.
