Embodiment Construction

[0135] The specific implementation manner of the present invention will be described in detail below in conjunction with the technical scheme and the accompanying drawings.

[0136] refer to Figure 1 ~ Figure 3 , an intelligent optimization method for production scheduling in the production process of a process industry enterprise. The scheduling determines the flow rate of each continuous production equipment in each time period and the processing capacity (batch) of each intermittent production equipment in each time period on the production line, so that target optimization. Composition block diagram such as figure 1 As shown, it consists of three parts: model construction, scheduling scheme compilation, and database system. The scheduling scheme compilation part adopts the differential evolution algorithm as the solution algorithm of the model.

[0137] 1) Scheduling model establishment

[0138] In order to facilitate modeling and algorithm solution, the scheduling ra...

Abstract

The invention relates to a method for intelligently optimizing production scheduling of the production process of a flow industry enterprise, relating to the construction of scheduling model and the design of solution algorithm. The method comprises the following steps: building an intermittent and continuous mixed production process scheduling model with finite intermediate storage for the flow industry by adopting a unified time discretization method; and providing a new coding mode, and designing an optimization method for differential evolution with the corresponding evolutionary operation as the model based on a new coding mode. The provided model and algorithm have simple operation and fast calculation speed, can determine the flow velocity in each time segment for each continuous device on a production line and determine the handling capacity (batch quantity) in each time segment for each intermittent production device, thereby optimizing the target and improving the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of automation, and relates to a method for scheduling and optimizing the production process of process industry enterprises. Background technique [0002] The process industry mainly adds value to raw materials through physical or chemical methods such as mixing, separating, and heating. It includes both continuous and batch types of production processes. During the processing of the continuous production process, the input material "flows" into the equipment at a certain flow rate, and at the same time, the output material also continuously "flows" out of the equipment at a certain flow rate; At a certain moment, everything is invested in the equipment and after a certain period of time, there will be output. [0003] Production scheduling is one of the key links in the implementation of CIMS in the process industry. Compared with discrete industry, process industry includes batch process and continuous ...
