[0081] S7. Obtain the estimated delivery cycle according to the second allocation quantity and the first production efficiency;

[0082] S8. Judge whether the estimated delivery cycle is greater than the expected value;

[0083] If the estimated delivery cycle is not greater than the expected value, it is determined that the second allocation quantity meets the expected production requirements;

[0084] If the estimated delivery cycle is greater than the expected value, adjust the product transfer efficiency until the estimated delivery cycle is not greater than the expected value, so that the second allocation quantity meets the expected production requirements.

[0085] As described in the above steps S1 - S8, a PCB is an electronic component that provides electrical connections and mechanical support for electronic components. With the development of miniaturization and high - performance of electronic devices, the production process of PCBs has become increasingly complex, and the requirements for production management have also been increasing day by day. Traditional extensive management is difficult to meet the needs of high - precision and high - reliability PCB production. Therefore, the multi - area management method has emerged. By subdividing the production process areas, it can more accurately control each link in the production process. This management method aims to improve production efficiency, ensure product quality, optimize resource allocation, and better handle complex situations in the production process. Currently, during the production process of PCBs, the order quantity often changes. When the order quantity changes, in order to achieve the expected production target, it is usually necessary to allocate production tasks according to the production capacity of the production line. However, this allocation method has the situation that the production tasks do not match the production capacity of different production process areas in the production line, resulting in the problem that the final production result does not meet the production expectation. And the present invention obtains multiple production line information and multiple production monitoring information for PCB production. Among them, the production line information refers to the key production process areas that make up the complete PCB production process, mainly including the graphic process area, the lamination process area, the surface process area, and the forming process area. The production monitoring information refers to the detailed records of the product processing conditions in each production line and each production process area during PCB production. Then, the inbound and outbound time information and the inbound and outbound quantity information are obtained according to the production monitoring information. Among them, the inbound and outbound time information refers to the specific time when products enter and exit each production line and each production process area, and the inbound and outbound quantity information refers to the specific quantity of products entering and exiting each production line and each production process area. The inbound and outbound time information and the inbound and outbound quantity information can accurately reflect the flow of products on the production line. Immediately afterwards, the first production efficiency of each production process area and the in - line product production progress value of each production line are calculated using the inbound and outbound time information and the inbound and outbound quantity information. Among them, the first production efficiency refers to the individual production efficiency of each production process area on each production line, and the in - line product production progress value refers to the production progress of the products in the production state in a single production process area. The in - line product production progress value can intuitively present the current progress of the products on the production line. Then, the second production efficiency of each production line is calculated using the inbound and outbound time information, the inbound and outbound quantity information, and the in - line product production progress value. Among them, the second production efficiency refers to the overall production efficiency of each production line. The calculation of the second production efficiency comprehensively considers the production efficiency of each production process area on each production line and the current production progress of each production process area, thus providing a more accurate indicator for the evaluation of the overall production efficiency of the production line. Then, the first allocation quantity of each production line is obtained according to the order change information and the second production efficiency. Among them, the order change information refers to the relevant information that the order content changes due to various factors after the customer places an order.The first allocated quantity refers to the specific production quantity allocated to each production line according to the order change information, so as to facilitate timely adjustment of the task allocation of the production line according to the changes in order requirements, avoid production chaos or resource waste caused by order changes. Subsequently, the second allocated quantity is calculated based on the first production efficiency, product transfer efficiency, and the first allocated quantity. Among them, the product transfer efficiency refers to the efficiency of transferring products from a certain production process area of a production line to subsequent production process areas in the same or another production line. The second allocated quantity refers to the specific quantity of products transferred from a certain production process area of a production line to subsequent production process areas in the same or another production line. By analyzing the transfer efficiency of products between different production process areas, combined with the production efficiency of different production process areas and the preliminary product allocation quantity of each production line, the production task allocation is further optimized, making the production task allocation more scientific and reasonable, avoiding affecting the overall production progress due to transfer efficiency problems, and improving the coherence and coordination of the production process. Then, the estimated delivery cycle is obtained based on the second allocated quantity and the first production efficiency. Among them, the estimated delivery cycle refers to the time required for all production lines to jointly achieve the specified product processing quantity in the order change information. Finally, the estimated delivery cycle is compared with the expected value to determine whether the current production task allocation meets the expected requirements. If the estimated delivery cycle is greater than the expected value, it is determined that the current production task allocation does not meet the expected requirements, and then the production task allocation is re-optimized by adjusting the key factor of product transfer efficiency to ensure that the expected production requirements are finally met. Through this dynamic adjustment mechanism, production management can be continuously optimized according to the actual situation. Through iterative adjustment, a production plan that meets the expectations can be gradually found, effectively solving the problem of delivery delay and ensuring the realization of production goals.

[0086] In one embodiment, the step of calculating the first production efficiency of each production process area and the online product production progress value of each production line according to the inbound and outbound time information and the inbound and outbound quantity information includes:

[0087] S31. Obtain the single-area product completion quantity of each production process area according to the inbound and outbound quantity information;

[0088] S32. Obtain the single-area product processing time of each production process area according to the inbound and outbound time information;

[0089] S33. Obtain the first production efficiency of each production process area according to the single-area product completion quantity of each and the corresponding single-area product processing time;

[0090] S34. Obtain the weight coefficient corresponding to each production process area;

[0091] S35. Calculate the online product production progress value of each production line based on the completion quantity of each single - area product and the weight coefficient. The calculation formula is as follows:

[0092] ;

[0093] where Z i represents the online product production progress value of the i - th production line, y ij represents the completion quantity of single - area products in the j - th production process area of the i - th production line, w ij represents the weight coefficient corresponding to the j - th production process area of the i - th production line, and n i represents the number of production process areas in the i - th production line.

[0094] As described in the above steps S31 - S35, in the present invention, by obtaining the completion quantity of single - area products and the processing time of single - area products in each production process area, where the completion quantity of single - area products refers to the quantity of products processed and completed in a single production process area of a single production line, and the processing time of single - area products refers to the processing time of products in a single production process area of a single production line. The single production process area can be evaluated separately through the completion quantity of single - area products and the processing time of single - area products. Then, dividing the completion quantity of single - area products by the corresponding processing time of single - area products can obtain the first production efficiency of the corresponding production process area. The first production efficiency is a quantitative evaluation of the production capacity of each production process area. At the same time, considering that the importance of different production process areas in the whole production line is different, by obtaining the weight coefficient corresponding to each production process area, the contribution degree of each production process area to the overall production progress of the production line can be more accurately reflected. Finally, by comprehensively considering the product completion quantity of each production process area and its corresponding weight coefficient, the online product production progress value of the whole production line is calculated. The online product production progress value can be used for the accurate calculation of the second production efficiency of each subsequent production line.

[0095] In one embodiment, step S4 of calculating the second production efficiency of each production line according to the inbound and outbound time information, inbound and outbound quantity information, and online product production progress value includes:

[0096] S41. Obtain the total input quantity and total completion quantity of products for each production line according to the inbound and outbound quantity information;

[0097] S42. Obtain the online product quantity of each production line according to the total input quantity and total completion quantity of products;

[0098] S43. Obtain the single - line product processing time of each production line according to the inbound and outbound time information;

[0099] S44. Calculate the second production efficiency of each production line based on the total number of products completed, the number of in-line products, the in-line product production progress value, and the single-line product processing time of each production line. The calculation formula is as follows:

[0100] ;

[0101] where E i represents the second production efficiency of the i-th production line, M i represents the total number of products completed on the i-th production line, N i represents the number of in-line products on the i-th production line, Z i represents the in-line product production progress value of the i-th production line, and T i represents the single-line product processing time of the i-th production line.

[0102] As described in the above steps S41 - S44, the present invention obtains the number of in-line products of each production line by calculating the difference between the total number of products input and the total number of products completed. Here, the total number of products input refers to the number of products input into a single production line, the total number of products completed refers to the number of products processed and completed by the corresponding production line, and the number of in-line products refers to the number of products that have been input into the production line but not yet processed. Then, according to the total number of products completed, the number of in-line products, the in-line product production progress value, and the single-line product processing time of each production line, the second production efficiency of each production line is calculated according to a specific formula. Among them, the single-line product processing time refers to the time for which a single production line has processed products. The total number of products completed in the specific formula reflects the completed production results, and the number of in-line products and the production progress value take into account the status of the products on the current production line. Through this comprehensive calculation method, the actual production capacity of the production line can be more comprehensively and accurately reflected.

[0103] In one embodiment, step S5 of obtaining the first allocation quantity of each production line according to the order change information and the second production efficiency includes:

[0104] S51. Obtain the production defect information of PCB production according to the production monitoring information, and obtain the number of production defects according to the production defect information;

[0105] S52. Obtain the total product inventory according to the total number of products completed on each production line, and obtain the number of products completed according to the total product inventory and the number of production defects;

[0106] S53. Obtain the order change quantity according to the order change information, and obtain the number of products to be processed according to the order change quantity and the number of products completed;

[0107] S54. Obtain the first allocation quantity of each production line according to the quantity of products to be processed and each second production efficiency.

[0108] As described in the above steps 51 - S54, in the present invention, the production defective quantity is obtained according to the production defective information, where the production defective information refers to the situation of products with quality problems during the production process, and the production defective quantity refers to the number of products with quality problems during the production process. The completed quantity of products is obtained according to the difference between the total inventory of products and the production defective quantity, where the total inventory of products refers to the sum of the quantities of products that have been processed and completed by all production lines, and the completed quantity of products refers to the sum of the quantities of qualified products that have been processed and completed by all production lines after removing the defective products. Then, the quantity of products to be processed is obtained according to the difference between the order change quantity and the completed quantity of products, where the quantity of products to be processed refers to the number of products that still need to be processed. Finally, the first allocation quantity of each production line is obtained according to the quantity of products to be processed and the second production efficiency. The calculation formula for the first allocation quantity of a single production line is: First Allocation Quantity = Quantity of Products to be Processed * (Second Production Efficiency of a Single Production Line / Sum of Second Production Efficiencies of All Production Lines). This allocation method can make full use of the production capacity of each production line and is conducive to improving the overall production efficiency.

[0109] In one embodiment, step S6 of calculating the second allocation quantity according to the first production efficiency, product transfer efficiency, and first allocation quantity includes:

[0110] S61. Calculate the harmonic production efficiency of each production process area according to the first production efficiency and product transfer efficiency. The calculation formula is:

[0111] ;

[0112] where S ij represents the harmonic production efficiency of the jth production process area in the ith production line, e hf represents the product transfer efficiency of transferring products from the fth production process area in the hth production line to the jth production process area in the ith production line, and r ij represents the first production efficiency of the jth production process area in the ith production line;

[0113] S62. Calculate the second allocation quantity according to the harmonic production efficiency and the first allocation quantity. The calculation formula is:

[0114] ;

[0115] where X vij represents the second allocation quantity of the vth production line transferring products to the jth production process area in the ith production line, and P iRepresents the first allocation quantity of the i-th production line, S ij Represents the harmonic production efficiency of the j-th production process area in the i-th production line, and n represents the number of production process areas.

[0116] As described in the above steps S61 - S62, the present invention combines the first production efficiency and the product transfer efficiency, and calculates the harmonic production efficiency through a specific formula. Among them, the harmonic production efficiency is an index that comprehensively considers the production capacity of the production process area itself and the transfer efficiency of products between different production process areas. The first production efficiency represents the production capacity of the production process area itself, and the product transfer efficiency represents the smoothness of product transfer between production process areas. Then, the second allocation quantity is calculated based on the harmonic production efficiency and the first allocation quantity. Allocating based on the harmonic production efficiency can make full use of the comprehensive advantages of each production process area. The purpose is to ensure that each production process area can undertake a reasonable production task volume according to its actual capacity, making the distribution of production tasks among regions more reasonable. This helps to reduce waiting time and resource waste during the production process, thereby improving the production efficiency of the entire production line.

[0117] In one embodiment, the step S7 of obtaining the estimated delivery cycle according to the second allocation quantity and the first production efficiency includes:

[0118] S71. Obtain the production demand time of each production process area according to the second allocation quantity and the corresponding first production efficiency of each production process area;

[0119] S72. Obtain the transfer demand time of each production process area according to the second allocation quantity and the corresponding product transfer efficiency of each production process area;

[0120] S73. Sort the production demand time and the corresponding transfer demand time of each production process area in terms of magnitude, take the larger value as the single - area completion demand time, and obtain the single - line completion demand time according to the multiple single - area completion demand times in each production line;

[0121] S74. Sort the multiple single - line completion demand times in terms of magnitude, and take the larger value as the estimated delivery cycle.

[0122] As described in the above steps S71 - S74, the present invention obtains the production demand time of each production process area by dividing the second allocation quantity of each production process area by the corresponding first production efficiency, and obtains the transfer demand time of each production process area by dividing the second allocation quantity of each production process area by the corresponding product transfer efficiency. For each production process area, since the completion of the product depends not only on production but also on transfer, the larger value between the production demand time and the transfer demand time is taken as the single - area completion demand time. Here, the single - area completion demand time refers to the time required for a single production process area to complete the processing work of a specified quantity of products. On this basis, the single - area completion demand times of multiple production process areas within a production line are further integrated to obtain the single - line completion demand time. Here, the single - line completion demand time refers to the time required for a single production line to complete the processing work of a specified quantity of products. Finally, the single - line completion demand times of different production lines are compared, and the maximum value among them is selected as the estimated delivery cycle, which is an overall estimate of the delivery time of the entire PCB production. The estimated delivery cycle provides a reliable delivery cycle prediction for the enterprise.
