The invention discloses an automatic business travel itinerary optimization method, and relates to the technical field of intelligent
itinerary planning, and the method comprises the steps: integrating the multi-source heterogeneous data of enterprise policies, personal preferences and real-time traffic through a
federated learning framework, and achieving the cross-
domain knowledge sharing; the method comprises the following steps: constructing a staged optimization engine by adopting an attention mechanism to dynamically balance cost, time, comfort and
sustainability targets: in the first stage, modularly disassembling a travel through
sparse constraint linear programming, and quickly generating a Pareto frontier candidate set; in the
secondary stage, on the basis of a multi-agent
reinforcement learning framework, complex interaction is simulated through a Markov
decision process, and strategy iteration is driven through a special reward function for quantifying a
comfort index; in order to cope with real-time disturbance, event-driven
edge computing nodes are deployed,
flight delay and traffic jam emergencies are responded in real time, an incremental topology updating
algorithm is triggered, and only affected sub-modules are reconstructed to reduce computing complexity. According to the invention, the
bottleneck of dynamic adjustment efficiency and multi-target balance capability is solved.
