Systems and methods are disclosed for receiving inputs at a portable
computer used by personal typically operating a delivery vehicle
providing delivery services, where the inputs potentially impact
completion of a pre-established dispatch plan according to certain
delivery criteria. The inputs include modifications to the manifest,
updates regarding weather or traffic conditions, or other factors
impacting the remaining deliveries. The inputs are examined to determine
if modification of the original dispatch plan are warranted, and if so, a
signal is generated triggering the processing of the original dispatch
plan to produce an updated dispatch plan meeting the certain delivery
criteria. The certain delivery criteria may involve commitments for
completing deliveries by certain time frames.
