Workflow engine automatic scheduling method of AI service platform

The invention discloses a workflow engine automatic scheduling method of an AI service platform, which comprises the following steps: 1) the AI service platform customizes a flow definition of AI service for a user, and maintains an AI service instance queue Q to be activated; 2) a user sets the values of an execution duration limit Tclimit and a waiting execution duration limit TwLimit for a task occupying computing resources in the AI service, and starts an instance of the AI service; 3) the AI service platform calculates the execution duration Tc of the task occupying the computing resource in the AI service instance started by the user; and 4) the AI service platform schedules the AI service instance started by the user according to the calculated execution duration Tc in combination with the use condition of the current computing resource of the AI service platform and the information of the queue to be activated. According to the invention, under the condition that the computing resources of the AI serv
