1. A method to re-identify a carrier on a laboratory transport system, wherein the carrier is associated with an identity, wherein the carrier is configured to move over a transport plane of the laboratory transport system, wherein the laboratory transport system comprises a monitoring system configured to monitor motion positions of the carrier on the transport plane when the laboratory transport system is activated, wherein the laboratory transport system comprises a control unit, the method comprising:
a) monitoring, by the monitoring system, motion positions of the carrier on the transport plane;
b) generating, by the control unit, log data of the carrier and the associated identity based on the monitored motion positions;
c) predicting, by the control unit, the position of the identity based on the generated log data after a system failure of the laboratory transport system, wherein the system failure is a monitoring system failure that causes dissociation of the identity from the carrier, wherein after the system failure, the carrier keeps moving on the transport plane;
d) detecting, by the monitoring system, the actual position of the carrier after reactivation of the laboratory transport system;
e) comparing, by the control unit, the predicted position of the identity with the actual position of the carrier; and
f) assigning, by the control unit, the identity to the carrier if the predicted position of the identity matches with the actual position of the carrier.
