Operation mode is widely used in a refinery production process, bringing great convenience to its daily operations. However, the refinery scheduling model with operation mode makes the scheduling model become large and thus difficult to solve. In this article, we present a new refinery scheduling model based on Variable Driven Modelling (VDM) approach. The proposed model is with less variables, less constraints, and less branching nodes compared with the existing works. Furthermore, VDM builds model from a novel aspect of variable (i.e. variable-based), while the traditional method building model from rule aspect (i.e. rule-based). The model built by VDM has a more stable form and better readability, and is beneficial for building a widely applicable and standard refinery scheduling model. The results of numerical experiments show computational advantages of the proposed model.
