Description

Technical Field

[0001] This invention belongs to the field of automated storage and retrieval system (AS / RS) technology, and particularly relates to a material kitting preparation method and AS / RS system for aerospace products. Background Technology

[0002] Aerospace product assembly consists of a variety of materials. Due to the large variety and complexity of the products, there are even more materials, including parts, components, cables, etc. Some of these materials are heavy and difficult to handle. Currently, aerospace companies mostly use automated storage and retrieval systems (AS / RS) for material storage and management, enabling material entry and exit and ledger management, which can save manpower and improve management efficiency.

[0003] Under normal circumstances, aerospace product production plans involve assembling only after all necessary materials are readily available. This requires manual verification using material ledgers in an automated storage and retrieval system (AS / RS), which is time-consuming and labor-intensive. Furthermore, retrieving materials one by one from the AS / RS according to assembly requirements after obtaining all materials is time-consuming and cannot quickly hand them over to assembly personnel, thus impacting production schedules. Providing direct information on material availability and enabling advance preparation for material availability could significantly improve production efficiency. Therefore, this paper proposes a material availability preparation method and an AS / RS system for aerospace products.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to provide a material kitting preparation method and automated warehouse system for aerospace products. This method combines product assembly material requirements to construct a product assembly BOM, enabling rapid calculation of the number of kitted materials and improving warehouse management efficiency. Furthermore, by integrating the product assembly BOM with material outbound processes, it achieves one-time outbound issuance of kitted materials, resolving the issue of multiple outbound shipments of individual materials in traditional kitting methods and improving operational efficiency.

[0006] To achieve the above objectives, the present invention proposes a material kitting preparation method for aerospace products, the material kitting preparation method comprising the following steps:

[0007] S1: Establish basic product information;

[0008] S2: Construct the product assembly BOM;

[0009] S3: Material completeness calculation;

[0010] S4: Complete set shipped out;

[0011] S5: Prepare all materials in advance.

[0012] Preferably, S1 specifically comprises:

[0013] Build detailed product data information to facilitate the management of products entering the warehouse. Basic product information includes product name, product code, product model and product type.

[0014] Preferably, S2 specifically includes:

[0015] Construct a product requirement BOM based on the product assembly process and assembly requirements, fill in the BOM association information in the automated storage and retrieval system, and create a product assembly BOM association table.

[0016] Preferably, the material kitting calculation method in S3 is as follows:

[0017] Based on the product assembly BOM, the system iterates through the inbound product data in the automated warehouse to obtain the total quantity of child products. Then, it calculates the possible matching quantities by comparing these quantities with the preset quantities of a single set constituting the parent product. Finally, it takes the minimum value among these as the possible matching quantities to satisfy product assembly. The specific steps are as follows:

[0018] S31: Let the parent product be A, the child product be ai, the product quantity be bi, the quantity per set be ci, and the matching quantity be di;

[0019] S32: Based on the product assembly BOM association table, obtain all the sub-products {a1,a2,...,an} required by product A;

[0020] S33: Use depth-first traversal to iterate and summarize the product inbound management data to obtain the inbound quantity of all sub-products {b1,b2,...,bn};

[0021] S34: Calculate the number of components for sub-products:

[0022] S35: Calculate the number of complete sets of materials for the product = min{d1, d2, ..., dn}.

[0023] Preferably, the method for preparing materials in advance in step S5 is as follows:

[0024] Based on the product assembly BOM, a parent product material kit box is designed to hold a certain number of child products. Warehouse managers can take out the complete sets of products in advance and put them into the material kit box, thus completing the product matching in advance. When assembling the product, the material kit box can be directly taken out of the warehouse and given to the assembly personnel.

[0025] An automated storage and retrieval system for aerospace products, and a method for preparing complete sets of materials in the automated storage and retrieval system.

[0028] 1. The kitting method designed in this invention for use in automated warehouses combines product assembly BOM and material warehousing to achieve one-time warehousing of kitted materials, solving the problem of multiple warehousing of single materials in traditional kitting methods and improving operational efficiency.

[0029] 2. The advance material preparation method designed in this invention combines the design of product material kits with the product assembly material requirements, and performs advance material preparation and re-entry into the warehouse. By advancing the material preparation time, when the product needs to be assembled, the product material kit can be issued in one go, saving outbound time, improving production efficiency, and effectively solving the problems of low efficiency and long material preparation time in traditional material kit management that relies on manual statistics. This also improves the management efficiency of automated warehouses. Attached Figure Description
