Hybrid production scheduling management and control method for polycrystalline silicon rods

Abstract

The invention discloses a hybrid production scheduling management and control method for polycrystalline silicon rods, and belongs to the technical field of hybrid production scheduling management andcontrol based on lean management. The technical problem to be solved is to provide an improvement of a hybrid production scheduling management and control method for polycrystalline silicon rods. Thetechnical scheme for solving the technical problem is as follows: the technical scheme is adopted; a manager inputs an annual production task and a monthly task into the data collection unit; the data collection unit sends the input data to the plan management unit; standard man-hour establishing management unit, inputting a production control instruction based on lean production practice data into the standard man-hour management unit: limiting the processing time of the polycrystalline silicon rod in each process, and feeding back actual production data and an early warning signal to the production process tracking unit when the processing time is set to exceed a preset man-hour or a man-hour saving state occurs; the method is applied to a mixed production scheduling place of the polycrystalline silicon rods.

Description

technical field [0001] The invention discloses a hybrid production scheduling control method for polycrystalline silicon rods, which belongs to the technical field of hybrid production scheduling control based on lean management. Background technique [0002] The production process of polysilicon ingots belongs to the combination of discrete and flow-based production methods. The ingot production process belongs to flow-based production management. It mainly adopts inventory, batch, and continuous production methods, and mixes, formulates, and heats raw materials. Physical or chemical methods increase the value of raw materials, and the subsequent silicon rod processing process belongs to discrete production, mainly through changing the physical shape of raw materials and turning them into products to increase their value. [0003] Since silicon ingot processing and polycrystalline ingot are two different production methods, the productivity of silicon ingot processing large...

Problems solved by technology

[0003] Since silicon ingot processing and polycrystalline ingot are two different production methods, the productivity of silicon ingot processing largely depends on the level of manual technology and coordination of equipment, while the production process of polycrystalline ingot is mostly automated Yes, the entire production process is controlled by equipment, and the time of different production equipment in the process of process operation will vary according to the time of the process. Due to changes in the process time of polycrystalline ingots, the number of polycrystalline silicon ingots that need to be processed after circulation will be unstable and uncertain; and the processing of polycrystalline silicon rods is mainly a labor-intensive process with a relatively low level of automation, so it is necessary to Have a good planning ability to balance the follow-up production. It is required to grasp the production situation of the front-end ingot in time, and carry out related work such as equipment maintenance, personnel adjustment, and capacity allocation in a timely manner, so as to avoid subsequent processing equipment being idle due to unstable ingot casting process. , or the backlog of work in progress and other phenomena occur, and the staff's work rhythm changes back and forth, which is easy to be tired and slack, which in turn affects the output; based on the above analysis, the current hybrid production scheduling system applied to the production method of polycrystalline ingots has certain defects. needs improvement
