Model conversion method and device, computer equipment and storage medium

The invention relates to a model conversion method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a first model written by adopting a first program language; converting the at least one functional module into a second program language to obtain at least one converted functional module; converting the first port into a second port under the second program language, converting the at least one model element into a port variable in the second port, and obtaining the direction of the port variable and an associated variable of the port variable; and obtaining a second model according to the at least one converted functional module, a second port under the second program language, a port variable in the second port, a direction of the port variable and an associated variable of the port variable. And the model established under the MBSE can be converted in a lossless manner, so that the fault transmission direction can be conveniently determined when reliability an
