Abstract: Central Kitchen is now a point of public interest in the catering industry because of its unique advantage in reducing cost. As an emerging development trend of the catering industry in transforming and upgrading，central kitchen has certain short slabs in the cost control of product distribution，including the uncertainty of product demand. Acost uncertainty model of central kitchen product distribution is constructed based on the robust optimization theory；the uncertainty set of the model is made up of the first moment and second moment information of demand；then the uncertainty set is solved by using the linear decision rule and the optimization theory；and the usability of the model is validated by simulation and analysis of examples. The research results show that for the limited space to control the production cost，enterprises should pay more attention to controlling the product distribution cost of the central kitchen ，so as to reduce the operation cost of central kitchen. The risk source of the enterprises is the indeterminacy of product demand in the current changing times. Besides caring about the postmortem analysis of delivery cost control，businesses should also complete risk prediction and assessment in advance，and timely renew their risk control planning.
