The invention relates to the technical field of artificial intelligence, and discloses a workflow mutual exclusion relation verification method, device and equipment and a storage medium. Logic expressions among the expressions are extracted according to the expressions of branches, the logic expressions are verified based on a mutual exclusion verification rule, and an output result of the logicexpressions is obtained; Therefore, the expression combination of the mutually exclusive relationship is determined based on the output result, and the mutually exclusive expressions are marked, so that compared with the prior art, the inspection mode does not need to carry out assignment calculation on the expressions one by one, judgment is directly carried out from the logic relation, the calculation amount of data is greatly reduced, the verification efficiency is improved. Meanwhile, mutual exclusion of expressions is checked in advance, errors of rule configuration between branches are avoided, and configuration errors caused by the fact that multiple branch conditions are met at the same time are avoided. In addition, the invention also relates to a blockchain technology, and data such as expressions can be stored in the blockchain.
