Abstract: With the development of computing technology and data availability, an increasing attention is paid to data-driven and data-integrated decision making in practice and research. We propose a framework of Operational Data Analytics (ODA) and demonstrate its application through the example of newsvendor model. In this talk, we focus on the situation where we have full structural knowledge but may be uncertain about the statistical characterization of the model. The ODA framework integrates data into decision making by carefully formulating the data-integration model and the validation model. The data-integration model identifies an appropriate class of operational statistics (i.e., the decision as a statistics of the data) and the validation model finds the best performer among the operational statistics. In contrast to the traditional estimation-optimization approach, which does not optimize the actual performance measure, the ODA approach significantly improves decision quality especially when the data is limited.
