Embodiment Construction

[0066] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0067] Such as figure 1 As shown, a control method for a process industry production system specifically includes two steps:

[0068] Step 1: Construct a system model according to the production situation and production requirements of the process industry production system site, and draw a production flow chart;

[0069] The specific implementation and operation are as follows:

[0070] Step 1-1: According to the different functions of each system component in the production system, classify all system components in the production system. In this embodiment, they are divided into the following 6 categories: entry site, storage tank farm, production device , diversion point, confluence point and delivery site.

[0071] First, through on-the-spot investigation or review of production process description materials, all product...

Abstract

The invention discloses a control method of a process industry production system. The control method comprises the following steps: according to the site production situation and the production requirements of the process industry production system, constructing a system model, and drawing a production technological process chart; on the basis of the production technological process chart, determining the production information of the production system, and establishing a target function based on mixed integer linear programming; and taking system production benefit maximization as an optimization object to carry out optimization solution on the target function, and obtaining optimal production information used for controlling the process industry production system. The invention provides a feasible control method of the process industry production system, the control method realizes the combination of the unified modeling and the logistics optimization of the process industry production system, is effective and universal and can provide effective reference information for a production plan of the process industry for controlling.

Description

technical field [0001] The invention relates to the field of process industry production system modeling and scheduling optimization, in particular to a control method of process industry production system, which is realized by a modeling method based on over-planning optimization and a logistics optimization method based on mixed integer linear programming. Background technique [0002] The production system of the process industry often has the characteristics of large scale, complex production process, and difficult resource allocation. Therefore, the daily production and system scheduling optimization of the process industry often face the processing of a large amount of data and the optimal allocation of resources. With the continuous application and promotion of system optimization methods in the process industry, especially in the petrochemical field, the system modeling and optimization of the process industry has become an important research direction and field.
