Mainstream industrial solutions follow a multi-stage paradigm of model prediction, value calculation, and dispatch matching. Although dispatch quality is determined by the final batch-level assignment, these stages optimize different intermediate objectives. This cross-stage objective inconsistency means that improving a single stage does not necessarily improve the overall dispatch result. We therefore formulate Micro-View Order-Dispatching as a generative matching problem and propose GenMatch, an end-to-end Generative Matching framework and the first such framework deployed in a real-world production environment. Applying generative modeling to this problem introduces three challenges. First, each dispatch batch forms a dynamic sparse bipartite graph, requiring efficient structured batch-level encoding. Second, replacing the hand-crafted value function requires learning unified business utility from heterogeneous feedback. Third, directly generating an assignment requires tracking the evolving matching state because each selected order-driver pair changes the remaining feasible candidates. GenMatch addresses these challenges with a Context-Aware Bipartite Encoder, a Business-Aware Utility Learner, and a State-Aware Pointer Decoder. Extensive offline evaluations and online A/B tests in five cities across DiDi's international ride-hailing markets show consistent improvements over competitive baselines, confirming the effectiveness and practicality of GenMatch for industrial order-dispatching.", "url": "https://wpnews.pro/news/genmatch-an-end-to-end-generative-matching-framework-for-micro-view-order-in", "canonical_source": "https://arxiv.org/abs/2608.19751", "published_at": "2026-08-21 04:00:00+00:00", "updated_at": "2026-08-21 04:13:00.800896+00:00", "lang": "en", "topics": ["machine-learning", "generative-ai"], "entities": ["DiDi Global Inc.", "GenMatch", "arXiv"], "alternates": {"html": "https://wpnews.pro/news/genmatch-an-end-to-end-generative-matching-framework-for-micro-view-order-in", "markdown": "https://wpnews.pro/news/genmatch-an-end-to-end-generative-matching-framework-for-micro-view-order-in.md", "text": "https://wpnews.pro/news/genmatch-an-end-to-end-generative-matching-framework-for-micro-view-order-in.txt", "jsonld": "https://wpnews.pro/news/genmatch-an-end-to-end-generative-matching-framework-for-micro-view-order-in.jsonld"}}
