Full-chain molten iron combined transportation scheme system and evaluation method

The invention provides a full-chain molten iron combined transportation scheme system and evaluation method, and the method comprises the specific steps: S1, customer demand preference recognition: analyzing factors and types generated by customer demand preferences, and obtaining the evaluation and importance degree sorting of customers for different demand preferences; s2, generating a multimodal transport scheme model, including four parts: S21, model establishment, S22, model objective function establishment, S23, model constraint condition establishment, and S24, multi-objective model solving; and S3, scheme evaluation: evaluation indexes comprise economy, timeliness, convenience and safety, an evaluation index system is constructed according to demand preferences of clients, each evaluation index is endowed with different weights, and a G1 method, an entropy weight-fuzzy analytic hierarchy process and a combined weighting method are respectively adopted for analysis to obtain a multimodal transport sche
