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 sustainable scheduling method for a hybrid flow shop based on machine tool processing capability sorting, which solves the problem that machine tool characteristics are not fully considered in the prior art, and has the beneficial effects of actively selecting machine tools and improving the scheduling efficiency. According to the specific scheme, the sustainable scheduling method for the hybrid flow shop based on machine tool processing capability sorting comprises the steps that of establishing a machine tool machining capacity comprehensive evaluation system, and sorting the machining capacities of parallel machine tools; according to the sorting result of the parallel machine tools, realizing equipment selection for effective information of optimization iteration, and proposing an active decoding rule; taking finishing time and energy consumption as optimization objectives, carrying out directional selection of the machine tools in combination with an active decoding rule, and realizing sustainable scheduling of the hybrid flow shop based on a differential evolution algorithm of machine tool processing capacity.
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...
