Abstract

The invention provides a continuous time-based scheduling optimization method for an entire refinery. The continuous time-based scheduling optimization method for the entire refinery comprises the following steps: according to the stable operation mode that production devices of the refinery implement production process at event points and the transitional process produced when the operation mode is switched, the factory scheduling model for the entire refinery adopting the continuous time to indicate is obtained; according to the factory scheduling model for the entire refinery, a mixed integer non linear programming mathematical model is established and the mixed integer non linear programming mathematical model is subject to linearization treatment; according to the linearization mathematical model, scheduling is conducted on the refining process, storage and delivery of the refinery. The invention further provides a continuous time-based scheduling optimization system for the entire refinery. The continuous time-based scheduling optimization system for the entire refinery comprises a model establishing module, a linearization module and a scheduling module. The continuous time-based scheduling optimization method and system for the entire refinery can reduce the manufacturing cost and material storage cost during the production process, as well as the punishments caused by breach of order.

Description

technical field [0001] The invention relates to the technical field of intelligent scheduling optimization in the process industry, in particular to a method and system for scheduling optimization of the entire refinery based on continuous time. Background technique [0002] Production scheduling is an important tool to improve enterprise management level and obtain greater economic benefits. Due to the complexity of refinery short-term scheduling in its generation process, it has always been a very challenging problem. In refinery production, it is important to consider the mode switching of generating units to reflect the dynamics of the production process in the scheduling model. [0003] It is very necessary to consider the transition process caused by mode switching in the refinery scheduling model, because the mode switching in the refining production process is inevitable, and in different production modes, the operating cost and product yield of the production unit ...
