Personalized recommendation system for passenger travel scheme based on model-as-a-service architecture

The invention provides a passenger travel plan personalized recommendation system, and belongs to the technical field of urban rail transit travel service and digital governance. A data perception management module collects, processes, stores and analyzes rail transit data; the metadatabase management module carries out data maintenance, updating and management according to information feedback of the travel scheme recommendation and interaction service module; the core model management module carries out storage management on a system algorithm model, a knowledge base and tool application; and the travel scheme recommendation and interaction service module manages and recommends system application configuration, and manages and outputs a travel scheme of a system user. According to the method, the accuracy of a system recommendation algorithm model is improved, model parameters can be corrected in time by designing an online correction function of a business domain model algorithm management unit, and the sy
