Description
Technical Field
The invention belongs to the field of PCB manufacturing, and relates to a plate recommending method, a system and a medium.
Background
The board is the base of PCB processing and also an important component of PCB, and the cost and quality of the board also influence the processing cost and quality of PCB in a great program. When there are many kinds of boards of different brands that can meet the requirements of customers, how to reduce the cost of the boards to the maximum extent under the condition of ensuring the delivery quality becomes a research subject.
Currently, a plate brand (referred to as a "first brand") is generally confirmed according to a first communication result with a client and is used as a selection basis for subsequently processing the brand, and when the first brand is enough in stock, the brand is continuously used; when the first brand is in short stock, the change is made and other brands are used instead.
The method is simple and has the following defects:
1. the price of the brand confirmed for the first time is not always the lowest, and when the price of other brands is lower, the cost is wasted;
2. even if the application range of the brand with the lowest cost is determined later and the brand confirmed for the first time is updated, the operation is troublesome, especially for the company mainly producing the express plate (because the price of each brand can be continuously adjusted according to the market and the operation condition of the company, the lowest brand can be continuously changed.
3. The change in the case of insufficient stock may affect the quality of delivery, and when the brand numbers are delivered simultaneously, it is obvious that the lot consistency is not satisfied.

When no brand limit exists, the material number candidate brand is used, namely the brand stored in the step of determining the material number candidate brand, such as: there are three brands A/B/C. Determining a brand with enough stock from the material number candidate brands A/B/C, and judging whether brands meeting all core plate material receiving brands of the material number exist, such as: only brand B/C. Screening for sufficient brands in stock: all sufficient brands in stock are screened out. Determining the brand with the lowest sum of the comprehensive unit prices of the core boards: and (3) taking the brand with the lowest sum of comprehensive unit prices from sufficient brands stored in the stock, such as: brand B is lowest. The brand with the lowest sum of the latest brand, the brand after the change and the comprehensive unit price is saved. And finally, selecting the large material size corresponding to the minimum comprehensive unit price in the determined production single brand.
With further reference to fig. 8, in some embodiments, an upcoming expired sheet is determined from a sufficient inventory of brands, the upcoming expired sheet is saved in the production order use brand, an expiration threshold is set, and the upcoming expired sheet is preferentially selected when the expiration threshold is reached. By setting the rule of 'will expire the plate before leaving warehouse', the plate is made to leave warehouse before leaving warehouse, and cost waste caused by expiration is reduced.
With further reference to fig. 9, in some embodiments, the cost difference between the maximum material at the lowest comprehensive unit price and the maximum material to be received is compared, the waste amount of the production order is calculated, a waste amount threshold is set, and when the waste amount threshold is reached, a re-makeup application is initiated. And calculating the waste amount of the production order by comparing the cost difference between the large material with the lowest comprehensive unit price and the large material to be received, and further setting the authority. When the waste amount exceeds a certain limit, the application of re-splicing plates is initiated, and the utilization rate of the plates is improved and the waste is reduced through re-splicing plates.
