【内容简介】Modern retail and platform operations couple four levers—production, inventory, pricing, and recommendation—through shared inventory dynamics and a common profit objective, yet most models optimize subsets of these decisions in isolation. We formulate the integrated problem as a finite-horizon Markov decision process and develop the Pretrained Coordination Model (PCM), a management world model built on a single sequence-model backbone: it distills logged trajectories of incumbent heuristic and reinforcement-learning policies into one coordinated policy whose per-product tokenization keeps its parameter count invariant to the number of products; its shared dynamics and outcome heads answer counterfactual queries about joint decisions; and it improves decisions by planning over short imagined rollouts behind an error-calibrated guard. Our analysis provides a separability benchmark identifying when coordination pays, approximation and return-conditioned stitching guarantees under which the distilled policy can exceed every data-generating policy, an information-structure bound quantifying the cost of siloed control, and a guarded-improvement guarantee—exact in the deterministic limit—converting model accuracy into a no-regress planning property. Computational experiments show that (i) coordinated control raises expected profit and reduces dispersion relative to heuristic and deep reinforcement-learning baselines, most strongly under tight cross-process coupling and nonstationary demand; (ii) a single fixed-capacity policy trained from logs alone matches a full-information reference at small scale and retains roughly half to two-thirds of its performance as the assortment grows from 2 to 100 products, where a flat deep reinforcement-learning controller collapses; and (iii) operated in planning mode, PCM exceeds the full-information reference at small scale and matches it at larger scale—with higher service levels and fewer stockouts throughout—a gain traced through counterfactual evaluation to dynamics models trained with action coverage rather than expert logs alone.
