Abstract: One embodiment can provide a method and system for optimizing marketing plans. During operation, the system can collect historical customer data from a plurality of data sources, apply a machine learning technique to train a customer model based at least on the historical customer data, and obtain an initial marketing plan, which specifies a plan goal and one or more constraints. The system can perform an optimization process based on the initial marketing plan and the customer model. The system can further generate and present a report based on the optimization process, the report comprising an optimized marketing plan, thereby facilitating future marketing efforts based on the optimized marketing plan.
