Port cluster is the general trend of international port cluster development. Port cluster management can promote the specialization of enterprises in the cluster, realize the sharing of resources within the cluster, and improve the brand effect of enterprises in the cluster. The ultimate goal is to improve the core competitiveness of enterprises in the cluster. In this paper, a mathematical model is established for the collaborative inventory management among enterprises in port cluster with limited collaborative supply capacity, and the inventory synergy strategy is studied. According to the cooperative ordering strategy and the cooperative supply strategy, a bidirectional inventory Synergy model under limited cooperative supply capacity is established, and the improved multi-objective genetic algorithm combined with Nash equilibrium is used to solve this problem. Through the strategy of inventory coordination across the chain, the enterprise can reduce the inventory cost effectively, reduce the shortage cost and improve the profits of both sides. In this paper, the limitation of supply capacity is increased, which makes the situation of inventory synergy more diversified and closer to reality, and provides a research way and reference for inventory cooperation in port cluster.
