Combined with the operation mechanism of container terminal handling equipment system,based on entropy theory in system science,this paper studied the equipment fault state from the point of view of state uncertainty,analyzed the calculation method of equipment fault state uncertainty,put forward an evaluation model of container terminal handling equipment fault state aiming at the resultant value of equipment composition system,calculated the entropy of container terminal handling equipment fault state with resultant value as a parameter,and applied it to an actual example.This paper verifies the feasibility of entropy theory in studying the fault state of loading and unloading equipment in container terminals,and the role of the result value parameter in judging fault states of equipment.
