Embodiment Construction

[0055] refer to Figure 1-2 . The specific steps of the green dynamic scheduling method for flexible production of the present invention are as follows:

[0056] Step 1. Release the production plan and obtain the initial data related to processing as calculation parameters.

[0057] The initial data is obtained through data input, and the required parameters include: the number of processed workpieces n, the number of processing machines and equipment m, process constraints, and the power consumption E of the equipment production process.

[0058] Step 2. Based on the energy consumption model of the production workshop, adopt the Pareto multi-objective optimization method and equipment load balancing strategy, use the bat algorithm to design a green scheduling algorithm, calculate the static scheduling scheme, and execute the scheduling scheme.

[0059] Step 2.1: Set algorithm parameters.

[0060] Parameters related to the production process: the number of workpieces n; the...

Abstract

The present invention discloses a green dynamic scheduling method for flexible production, in order to solve the technical problem of poor practicality of the existing dynamic scheduling method for the flexible production. The technical scheme comprises: obtaining initial data parameters of production, and using an information physical system to enter basic information such as equipment, personnel, orders, equipment power consumption, materials and the like as initial calculation parameters for the scheduling; designing a green scheduling algorithm, taking the minimal processing time and the minimum production energy consumption as objectives, based on a Pareto multi-objective optimization theory and an energy consumption model of a manufacturing process, using the equipment load balancingstrategy, and using the bat algorithm to calculate and execute the scheduling scheme; and finally, implementing a dynamic scheduling strategy, using an event-driven strategy to determine whether disturbance events such as the machine failure, the order change, and the like occur, and if so, updating the data, and re-calling and executing the green scheduling algorithm until the entire productionis completed, so that green dynamic scheduling for the production is achieved, and good practicability is realized.

Description

technical field [0001] The invention relates to a dynamic scheduling method for flexible production, in particular to a green dynamic scheduling method for flexible production. Background technique [0002] Energy conservation and emission reduction is a basic national policy for the upgrading of my country's manufacturing industry and one of the research and development directions of intelligent manufacturing technology. The literature "Energy Consumption, Carbon Dioxide Emissions and the Sustainable Development of China's Industry, Economic Research, 2009, vol44(4), p41-55" points out that most of the energy consumption comes from industrial production, and China's total industrial energy consumption accounts for the total energy consumption 69.4% of the total, and 83.1% of the total carbon dioxide emissions. For the enterprise itself, saving energy can reduce the production cost of the enterprise and improve production efficiency. Therefore, reducing energy consumption ...
