An energy-saving scheduling model of a hybrid assembly line forging workshop under multiple time factors

Abstract

The invention discloses an energy-saving scheduling model of a hybrid assembly line forging workshop under multiple time factors. The model is established through the following steps that multiple time influence factors of all machining stages of the hybrid assembly line workshop are analyzed, wherein the time influence factors comprise the preparation time, the machining time, the adjustment time, the transportation time, the waiting time and the waiting balance time; Analyzing continuous machining of middle heating furnace equipment and discrete machining processes of other machining equipment in the mixed assembly line forging workshop; Establishing a completion time model by adopting a transportation time right shift sorting rule, and analyzing the relationship of multiple times in workshop scheduling; analyzing the energy consumption scheduling of the mixed flow forging workshop by utilizing a closing / opening scheme, and establishing an energy consumption scheduling model; And establishing a multi-objective function of the mixed flow forging workshop energy-saving scheduling model. According to the invention, a multi-objective model of completion time and energy consumption isestablished for the mixed flow forging workshop, and the model is used for solving the scheduling problem of the mixed flow forging workshop with the continuous machining characteristic of the heating furnace.

Description

technical field [0001] The invention relates to a scheduling technology of a mixed flow workshop, in particular to a modeling method of an energy-saving scheduling model for a mixed flow forging workshop, and belongs to the technical field of advanced manufacturing control and scheduling. Background technique [0002] With the rapid development of industry, rising energy prices and the current trend of sustainable development have brought new pressure to manufacturing enterprises, energy-saving scheduling has become one of the important research objectives of workshop scheduling. Different from the characteristics of the usual machining production line, the production in the forging workshop is a mixture of the continuous processing of the heating furnace and the discrete processing of other machining equipment. The production process is difficult to control and the energy loss is serious. In addition to the discrete energy consumed in machining operations, most of the energ...

AI Technical Summary

Problems solved by technology

Since the energy consumption of the equipment is still high in many different time states, it is impossible to estimate the actual wasted energy consumption of the equipment in production

At the same time, the subsequent processing of the heating furnace is continuous in the forging production, which increases the difficulty of production scheduling
