Embodiment 1
[0019] Such as figure 1 As shown, the embodiment of the present invention provides a resource scheduling method for a flow shop, which specifically includes the following steps:
[0020] Step 101: Process each order in batches according to the delivery date, and obtain different batches of sub-orders of each order.
[0021] Wherein, the delivery period refers to the delivery date recorded in the order, and may also refer to the time period from the current moment to the delivery date, that is, the delivery period. In the same order, workpieces to be processed with the same delivery date are divided into sub-orders of the same batch. This refers to batching the orders to be processed as a whole, and splitting each order according to the actual demand (order delivery date, etc.), so as to realize the rough split of the order. For example, suppose there are 5 orders currently to be processed, and if order 1 records two delivery dates, order 1 is divided into two sub-orders acco...
Embodiment 2
[0048] The above embodiment 1 introduces the resource scheduling method of the flow shop of the present invention from different application scenarios, and the following embodiment will further introduce the corresponding device in conjunction with the accompanying drawings.
[0049] Such as figure 2 As shown, the resource scheduling device of the flow shop in the embodiment of the present invention includes:
[0050] The batching module 21 is used to process each order in batches according to the delivery date to obtain sub-orders of different batches of each order; wherein, in the same order, workpieces to be processed with the same delivery date are divided into the same batch In the sub-order of times;
[0051] The obtaining module 22 is used to obtain the sub-orders of the batches closest to the delivery date in each order, as sub-orders to be allocated for each order;
[0052] The sorting module 23 is used to sort the sub-orders to be allocated according to the delive...

Abstract
The invention discloses a resource scheduling method and device for an assembly line. The method includes: batch processing each order according to the delivery date to obtain sub-orders of different batches of each order; obtaining the mid-range delivery date of each order The latest batch of sub-orders is used as sub-orders to be allocated for each order; the sub-orders to be allocated are sorted according to the delivery date to obtain a sequence to be processed; according to the processing capacity of the heat treatment furnace, the workpieces to be processed in the sequence to be processed are allocated to the corresponding pre-order equipment, and return to the step of obtaining the sub-order with the shortest delivery date in each order to update the sequence to be processed until the workpieces to be processed in each order are allocated to the corresponding pre-order equipment. By batching the orders according to the delivery date, assigning the workpieces to be processed to the corresponding pre-order equipment according to the capacity of the heat treatment furnace and iteratively updating the sub-orders, the flexible batching of orders and the coordinated scheduling of the flow workshop and the heat treatment process are realized. .
Description
technical field [0001] The invention relates to the field of manufacturing technology, in particular to a resource scheduling method for an assembly line. Background technique [0002] The flow shop scheduling problem is a commonly used model in the field of industrial production. It is generally described as n orders are processed on m machine tools, each workpiece contains h processes, each process is assigned to a different machine tool for processing, and each The machining path of the workpiece is the same. Heat treatment is one of the important processes in machinery manufacturing. The last process of the flow shop facing the heat treatment process becomes a heat treatment process. Due to the limitation of the processing capacity of the heat treatment furnace, how to improve the utilization rate of the heat treatment furnace and reduce the waiting time of the workpiece before the heat treatment process The length of time has become an urgent problem to be solved in th...
