Problems solved by technology
However, in the actual production process, it is common that advanced machine tools and old machine tools support production at the same time. These machine tools have different characteristics such as power consumption rate and cost consumption, without considering the processing capacity of machine tools, and oversimplification of machine tool allocation. Unable to achieve sustainable production

The invention discloses a method for sustainable scheduling of a mixed flow shop based on the sorting of machine tool processing capabilities, which solves the problem that the characteristics of machine tools are not fully considered in the prior art, and has the beneficial effect of being able to actively select machine tools and improve scheduling efficiency. The specific scheme is as follows: A sustainable scheduling method for mixed flow workshops based on the sorting of machine tool processing capabilities, including establishing a comprehensive evaluation system of machine tool processing capabilities, and sorting the processing capabilities of parallel machine tools; according to the sorting results of parallel machine tools, the effective information for optimization iterations is used to select equipment, and a proactive approach is proposed. Decoding rules: with completion time and energy consumption as the optimization goal, combined with active decoding rules for directional selection of machine tools, and based on the differential evolution algorithm of machine tool processing capabilities, sustainable scheduling of mixed flow workshops is realized.
Description
technical field [0001] The invention relates to the field of workshop scheduling, in particular to a sustainable scheduling method for mixed flow workshops based on sorting machine tool processing capabilities. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Over the past decade, environmental issues such as global warming and climate change have attracted widespread attention. Manufacturing consumes nearly half of the world's energy. In China, the industrial sector accounts for 71% of the total energy consumption, of which 81% comes from the manufacturing industry. Energy consumption is one of the important factors leading to environmental degradation, and manufacturers must find practical ways to reduce energy consumption. Due to less capital investment, operational strategy and scheduling are widely used. Hybrid flow shop scheduling...
