During operation, the system can obtain sample data corresponding to a service. The system can pre-determine, based on the sample data and the service, a basic parametric shape model and can generate a plurality of shape parameters for the basic parametric shape mode. The system can then generate one or more parametric shape models with different shapes based on the plurality of shape parameters. The system can determine goodness-of-fit of the one or more parametric shape models with respect to a pre-defined decision-making strategy. Next, the system can in response to determining that the goodness-of-fit of at least one parametric shape model satisfies a set of objectives, outputting the at least one parametric shape model as an optimum decision-making strategy for the service.Type: GrantFiled: July 31, 2020Date of Patent: May 7, 2024Assignee: ADVANCED NEW TECHNOLOGIES CO., LTD.Inventors: Dapeng Fu, Wenbiao Zhao, Hong Jin
