[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The production plan generation method provided by the embodiment of the present invention can be applied in Figure 1In the application environment, the client communicates with the server through the network. The manager inputs the production order through the client, and the server extracts the product information and production information of the target product to be produced in the production order from the client. Based on the product information of the target product to be produced in the production order, the target production line of the target product is formulated to determine the multiple production processes of the target product in the production process, and the processing time of the target product in each production process is estimated. After that, the scheduled production data and multiple constraints of the multiple production processes in the production period are obtained, and finally the production plan of the target product is generated based on the target production line, processing time, scheduled production data and multiple constraints. The above technical solution is adopted to realize automatic production scheduling, reduce the dependence on manual labor and workload in the production plan formulation process, simplify the production scheduling process, and improve the efficiency of production plan formulation. In addition, the production scheduling is realized by combining the processing time of the order with the factory's scheduled production data and constraints, and comprehensively considering factors such as time demand, resource availability and production capacity in the production process to ensure the feasibility of the production plan and resource utilization. Among them, the client can be but not limited to various personal computers, laptops, smart phones, tablets and portable wearable devices. The server side can be implemented by an independent server or a server cluster composed of multiple servers. The present invention is described in detail below through specific embodiments.

[0031] See also Figure 2 As shown, Figure 2 A flowchart of a production plan generation method provided by an embodiment of the present invention includes the following steps:

[0032] S10: Obtain product information and production information of the target product to be produced in the production order;

[0033] Among them, the production information includes the production quantity and production period of the target product.

[0034] The production plan generation method provided by the present invention can be applied to assembly production scenarios. Specifically, in the process of formulating a production plan for a production order, the target product to be produced contained in the production order is obtained. It should be noted that the target product is an assembly product, that is, it needs to be combined and assembled through multiple parts or components during the production process to finally form a complete functional product. The target product can be any line of products in the production order, or multiple lines of products. The staff can select one or more lines of products in the production order as the target product based on the production plan and formulate a production plan.

[0035] Optionally, the production information of the target product includes production quantity and production period.

[0036] In one embodiment of the present application, Figure 3As shown, a specific solution for obtaining the production information and product information of the target product is provided. In S10, the product information and production information of the target product to be produced in the production order are obtained, which specifically includes the following steps S11-S16:

[0037] S11: In response to the production plan generation request, obtaining a sales order included in the production plan generation request;

[0038] S12: based on the preset order conversion rules, convert the sales order into a production order;

[0039] For steps S11-S12, after the company's staff signs a sales order with the customer, they need to determine the number of products that need to be produced based on the number of goods in the sales order and schedule production for them. However, the order content of the sales order focuses more on business and external needs. If production scheduling is performed directly based on sales order information, it may lead to problems such as unreasonable allocation of production resources and inflexible production plans. In order to better coordinate the relationship between sales and production and ensure the rationality of the final production plan, when a production plan needs to be formulated, the sales order is first converted into a production order that focuses on production organization, and then production scheduling is performed based on the order information in the production order to optimize the production process and improve overall production efficiency. Specifically, after receiving a production plan generation request, the sales order included in the request is obtained, and the sales order is converted into a production order based on pre-set order conversion rules.

[0040] Optionally, the preset order conversion rules include a data mapping relationship between sales orders and production orders. In the process of formulating the order conversion rules, the product-related data to be converted (such as product code, quantity, production delivery date, sales delivery date, etc.) and the data format correspondence between the data to be converted in the sales order and the production order are determined, and then the preset order conversion rules are constructed based on the data to be converted and its format correspondence.

[0041] In actual application scenarios, sales orders generally come from ERP (Enterprise Resource Planning) systems and MES (Manufacturing Execution System) systems. Sales orders focus more on business and external needs, while production orders focus on production organization. Taking the MES system as an example, the sales order mentioned in the system refers to the sales order line, and the production order is also converted based on the sales order behavior. Sales-production conversion refers to the transfer of fields required for production and manufacturing (such as product code, quantity, production delivery date, sales delivery date, etc.), and fields not related to production (such as customer contact information, payment method, freight bearer, etc.) are not transferred. Specifically, the staff clicks on one or more rows in the sales order table on the client interface, and then clicks the "Order Conversion" button above the table to complete the conversion of sales orders to production orders, and modify the sales order status according to the converted quantity. In addition, select the sales order line and click the "Undo Conversion" button above the table to cancel all converted production orders and modify the sales order behavior to the initial conversion. If Figure 4 As shown, a sales order on the operation panel of an electronic device is converted into a production order display diagram. A standard order scheduling button is set on the operation panel of the electronic device that executes the production plan generation method of this scheme, or a standard order scheduling button is displayed on the display interface of the electronic device. When a staff member clicks the order scheduling button or button, a production plan production request is generated in response to the staff member's click operation. After the server obtains the production plan generation request, a production plan for the production order is formulated.

[0042] S13: Obtain product information, product delivery date, product delivery quantity, and order creation date of the target product in the production order;

[0043] S14: Obtain the product inventory of the target product;

[0044] S15: Determine the production quantity of the target product based on the product delivery quantity and product inventory.

[0045] For steps S13-S15, the product delivery quantity is the number of products that the target product production department needs to deliver, and the product inventory quantity of the target product is queried, and the production quantity to be produced this time is obtained by subtracting the product inventory quantity from the product delivery quantity.

[0046] S16: Determine the production preparation time of the target product based on the production quantity;

[0047] S17: Generate the production duration of the target product based on the product delivery date, order creation date and production preparation time.

[0048] For steps S16-S17, in addition to the production time, the product also needs to consider the time for preliminary preparation (such as raw material procurement), process waiting (such as equipment debugging), packaging and transportation during the production process. These times are summarized as the production preparation time. In order to ensure the accuracy of the production plan, the production preparation time of the target product under the production quantity is predicted based on past production basis. It can be understood that the production preparation time is usually hours. The production preparation time is converted into days. Based on the product delivery date, the production preparation days are subtracted to obtain the production delivery date, and then the production period of the product is calculated based on the production delivery date minus the order creation date.

[0049] In the actual application scenario, the production preparation time for producing 500 pieces of product 1 is predicted to be 5 days. The product delivery date given in the order information is November 30, 2022, so the production delivery date of product 1 is November 25, 2022, and the order creation date of the production order is November 10, 2022, so it can be determined that the production period of the target product is 15 days.

[0050] In actual application scenarios, obtain customer information in the sales order, query the priority of the customer and the product based on the customer information and product information, and determine whether an emergency order check is required based on the priority. Specifically, priority levels are established based on customer attributes, as well as customer types and product types corresponding to each priority level. For example, customers with the highest priority level of 1 require special exceptions for emergency order insertion, that is, when formulating the production plan for this customer, the production of all its products is ranked first. If production plans are formulated for production orders of multiple sales orders at the same time, the multiple production orders are sorted based on the priorities corresponding to the customers and products of the multiple sales orders, and then production plans are formulated in sequence based on the sorting results.

[0051] S20: Generate each product of the target production line of the target product based on the product information;

[0052] Among them, the target production line includes multiple production processes;

[0053] In this step, based on the product information of the target product, the multiple production processes required to produce the product and the processing order of each production process are determined, and the multiple production processes are combined to obtain the target production line of the target product in the production process.

[0054] In one embodiment of the present application, a specific target production line construction scheme is provided. In S20, a target production line of a target product is generated based on product information, which specifically includes the following steps S21-S23:

[0055] S21: Based on the product information, determine the production process of the target product in the production process in the first preset mapping relationship;

[0056] Wherein, the first preset mapping relationship includes the corresponding relationship between the product and the production process;

[0057] S22: Based on the production process, determine multiple production processes of the target product, production equipment and materials for each production process in the second preset mapping relationship;

[0058] The second preset mapping relationship includes the corresponding relationship between the production process and the production process;

[0059] S23: Generate a target production line for a target product based on multiple production processes, production equipment and materials corresponding to each production process;

[0060] Among them, product information includes product name, product model and product specifications.

[0061] For steps S21-S23, in actual applications, the factory has at least one production line, and each production line usually has multiple production processes. During the production and processing of the products, the production tasks of each product in the production order will be assigned to each production process of each production line for production and processing. Before formulating a production plan, based on the product name, product model and product specifications of the target product, a query is made in the first preset mapping relationship to obtain a production process flow chart for the target product. Then, based on the production process flow chart, a query is made in the second preset mapping relationship to determine the multiple production processes of the target product in the production process, the production equipment and materials corresponding to each production process. The above-mentioned multiple production processes, the production equipment and materials of each production process are summarized to form a target production line for the target product.

[0062] Optionally, the first preset mapping relationship includes the correspondence between different products and their production processes; the second preset mapping relationship includes the correspondence between the production process and the production process.

[0063] In the actual application scenario, the product to be produced in the production order is product 1, and the product information of product 1, model a, specification b, is obtained. Based on product 1, model a and specification b, the corresponding production process flow is queried in the first preset mapping relationship: mechanical processing-surface treatment-assembly-testing. Based on the production process, the multiple production processes required for product 1 in the production process are determined: mechanical processing: including cutting process, drilling process, and grinding process; surface treatment: including cleaning process, spraying process, and drying process; assembly: including partial assembly process and general assembly process; testing: including functional testing process and performance testing process. Obtain the production equipment corresponding to each production process (for example, cutting process: cutting equipment C; general assembly process: assembly equipment G, etc.) and the materials corresponding to each production process (for example, cutting process-raw material D, cleaning process-cleaning agent F, partial assembly-semi-finished product H, etc.). Based on the above multiple production processes, the production equipment and materials of each production process are summarized to form the target production line of product 1.

[0064] S30: Based on the target production line, determine the processing hours required for each production process of the target product;

[0065] In this step, the standard working hours of the production equipment required for the production and processing of the target product in each production process and the material processing time of the materials processed in each production process are obtained, and then the processing hours of the target product in each production process are calculated.

[0066] Through the above method, the processing time of the target product in each process can be estimated in advance, so as to formulate a more reasonable production plan and avoid idle or excessive use of resources.

[0067] In one embodiment of the present application, a scheme for specifically determining the processing time of a target product in each production process is provided. In S30, that is, based on a target production line, the processing time required for the target product in each production process is determined, which specifically includes the following steps S31-S33:

[0068] S31: Determine the standard working hours of the production equipment used in each production process of the target product based on the preset processing rule table;

[0069] S32: Determine the material processing time of the materials used in each production process of the target product based on the preset processing rule table;

[0070] S33: Based on the standard working hours and material processing time, determine the processing time of the target product in each production process.

[0071] For steps S31-S33, based on the preset processing rule table, find the standard working hours of the production equipment used in each production process of the target product and the material processing time of the materials used in each production process, add the standard working hours of the production equipment and the material processing time, and get the processing hours required for each production process of the target product on the target production line.

[0072] Optionally, the preset processing rule table includes equipment processing rules and material processing rules, wherein the equipment processing rules include the standard working hours of each production equipment in different production processes; the material processing rules include the processing time of each material in different production processes. In the historical production process, the processing time of each production equipment in each production process and the processing time of each material are collected, and these times are summarized to generate a preset processing planning table for each production process of the factory under different production equipment and different materials.

[0073] S40: Based on the target production line, determine the scheduled production data and multiple constraints within the production period;

[0074] In this step, when formulating the production plan, it is necessary to fully understand the factory's production progress, resource usage and other information to ensure the rationality of the formulated production plan and resource utilization. Specifically, based on the multiple production processes in the target production line of the target product and the production equipment and materials of each production process, determine the factory's scheduled production data for each production process within the production period and the constraints on production equipment and materials.

[0075] Through the above methods, the scheduled production data can be collected, the key constraints can be determined, and the production time of the products to be produced can be reasonably arranged to avoid conflicts with existing production tasks. This can ensure the scientific nature and feasibility of the production plan, improve production efficiency and resource utilization, and meet the requirements of product quality and delivery deadlines.

[0076] In one embodiment of the present application, a specific solution for determining the scheduled production data and multiple constraint conditions is provided. In S40, based on the target production line, the processing time required for each production process of the target product is determined, which specifically includes the following steps S41-S43:

[0077] S41: Acquire multiple management data during the production period;

[0078] Among them, a number of management data include production schedules, production equipment maintenance schedules, worker shift schedules, and material supply schedules;

[0079] It is very important to obtain a number of management data of the factory during the production period in order to formulate a production plan. The management data includes the factory's production schedule, production equipment maintenance table, worker shift table and material supply table during the production period. Among them, the production schedule includes the product information (such as product name, product number, product type) and production information (such as expected start time, end time, production quantity) that have been scheduled in each production process; the production equipment maintenance table includes the maintenance plan information of the production equipment (such as equipment number, type, expected maintenance date, downtime); the worker shift table includes the worker shift arrangement (such as worker number, name, shift date, start and end time, assigned tasks); the material supply table includes the inventory and supply status of materials (such as material number, name, inventory quantity, supply cycle and expected arrival time).

[0080] S42: Based on the target production line, determine the scheduled production data corresponding to the multiple production processes in the production schedule table;

[0081] In this step, based on the target production line of the target product, the scheduled production data corresponding to multiple production processes of the target product in the production process are filtered out in the production schedule, including the product name, type, production quantity of each product, estimated start time of the process, estimated end time, equipment number for executing the process, worker number for executing the process, and material number required for the process.

[0082] S43: Based on the production equipment maintenance table, worker shift table and material supply table, determine multiple constraints of the target production line within the production period;

[0083] Among them, multiple constraints include production equipment usage time constraints, worker shift constraints, material supply constraints, and process switching constraints.

[0084] In this step, based on the factory's production equipment maintenance table and worker shift table during the production period, determine the production equipment usage time constraints for the multiple production processes included in the target production line during the production period, including the maintenance time and downtime of each equipment; based on the worker shift table, determine each worker's shift schedule, available working time and rest time; based on the factory's material supply table during the production period, determine the material supply constraints for the materials required for each production process, including the material supply quantity and the estimated arrival time; considering the time required for equipment adjustment and worker shift changes, determine the process switching time constraints between multiple production processes based on the processing sequence between multiple production processes.

[0085] Through the above method, by organizing and analyzing the production equipment maintenance table, worker shift table and material supply table in detail, the specific constraints of the target production line within the production period can be clearly determined, and then assist in formulating the production plan to ensure the scientificity and feasibility of the production plan.

[0086] S50: Generate a production plan for the target product based on the target production line, processing hours, scheduled production data, and multiple constraints.

[0087] In this step, based on the scheduled production data and multiple constraints, the available production data that can be scheduled for each production process in the target production line within the production period is determined, including at least one available working day that can be scheduled, the estimated start time and the estimated end time of each working day. Subsequently, based on the processing hours, production quantity and schedulable data of each production process of the target product, the production tasks are allocated, and at least one scheduled production date within the production period and the production volume of each scheduled production date are determined for the target product.

[0088] In one embodiment of the present application, a specific production plan is provided. In S40, a production plan for a target product is generated based on a target production line, processing hours, scheduled production data, and multiple constraints. The steps S51-S58 are specifically included:

[0089] S51: Based on the usage time constraint of the production equipment, determine the available production time of each production equipment in the target production line within the production period;

[0090] S52: Determine the available working time of each worker in the target production line within the production period based on the worker shift constraints;

[0091] S53: Determine the estimated arrival time of out-of-stock materials in the target production line based on the material supply constraints;

[0092] S54: Determine the switching waiting time between multiple production processes based on the process switching constraint;

[0093] For steps S51-S54, based on the production equipment maintenance constraints, determine the available production time of each equipment in the target production line; based on the material supply constraints, determine the supply time of out-of-stock materials in the target production line; based on the worker shift constraints, determine the available working time of each worker in the target production line; based on the process switching constraints, analyze the equipment adjustment, worker shift handover and transfer time between the upper and lower processes, and then determine the switching waiting time between each production process.

[0094] S55: Determine the schedulable production data of multiple production processes in the target production line based on the scheduled production data, available production time, available working time, expected arrival time, and process switching time;

[0095] The schedulable production data includes at least one schedulable production date for each production process within the production period, as well as the estimated start time, estimated end time and schedulable production hours for each schedulable production date;

[0096] In this step, based on the scheduled data, the schedulable date of each production process in the target production line within the production period, as well as the estimated start time and estimated end time of each schedulable date are determined. It should be noted that in the process of determining the schedulable data of the production process, in order to ensure the accuracy of the production schedule, it is necessary to combine the relevant time of each production equipment, operator and material in each production process on the basis of the schedulable situation of each production process, so as to ensure that the production schedule of the production process meets the working requirements of the production equipment, operator and material. Therefore, based on the schedulable time of the production equipment, the available working time of the operator and the estimated arrival time of the out-of-stock material combined with the above-mentioned production process scheduling data, the final schedulable data of multiple production processes in the target production line is generated, including at least one schedulable date of each production process within the production period, and the estimated start time and estimated end time of each schedulable date, and the schedulable working hours of each scheduling date are calculated by the estimated start time and the estimated end time.

[0097] S56: Determine the total processing time of each production process based on the production quantity and the processing time of the target product in each production process;

[0098] S57: Based on the schedulable production data and total processing time of each production process, determine at least one production start date required for each production process of the target product and the production volume of each schedulable production date;

[0099] S58: Generate a production plan for the target product based on at least one schedulable date of each production process and the production volume of each schedulable date.

[0100] For steps S56-S58, the total processing time for each production process to produce the target product is calculated based on the production quantity of the target product and the processing time of each production process. Thereafter, the production volume of the target product on the schedulable date of each production process is determined based on the schedulable date of each production process and the total processing time. Finally, a production plan for the target product within the production period is generated based on the schedulable date of each production process and the production volume on each schedulable date.

[0101] Optionally, in order to improve the efficiency of production planning, a production scheduling optimization algorithm (such as legacy algorithm, linear programming, etc.) can also be used to optimize the production plan based on the processing hours of the target product in each production process, combined with the scheduled production data and multiple constraints.

[0102] In actual application scenarios, the production process and production volume of the target product in the production order on each production date can be listed in the form of a production schedule. During the production process, the production plan completion volume is updated in real time, so that relevant personnel can view the production plan based on the production order number. Figure 5 As shown, it is a production plan representation, where the production plan number is the number of the production order. The relevant personnel enter the production order number in the electronic device and click the "Plan Query" button to query the production plan of the order, including the production period (2022-06-01 to 2022-06-07), the production process required for at least one target product in the production order, and the planned progress of each production process on each production date. Furthermore, in order to facilitate the relevant personnel to understand the production plan more intuitively, the production date and production volume of each production process can also be sorted out, and the output of the target product is used as the benchmark to determine the output of the target product on each production date. A bar chart is drawn based on the production period, production quantity, production priority, at least production date and output of each production date of the target product to show it to the relevant personnel. As Figure 6 As shown, it is a bar chart of the production plan, where plan 1 is the target product 1. The priority of this product is 3, and it is expected to produce 340 units with a production period of 4 days. Based on the production plan, the production period is determined to be 75% on June 1 and 25% on June 2.

[0103] In one embodiment of the present application, in order to ensure the feasibility of the formulated production plan, after S57, that is, after determining at least one production start date and the production volume of each production start date required for the target product in each production process based on the schedulable production data and total processing time of each production process, the following steps S571-S573 are also included:

[0104] S571: Based on at least one production start date of each production process, determine the estimated production days required for the target product in each production process;

[0105] S572: Compare each estimated production day with the preset production day to determine whether the estimated production day is equal to or equal to the preset production day threshold;

[0106] S573: In any case where the estimated production days are greater than or equal to the preset production days threshold, overdue risk warning information is generated and sent to the terminal of the relevant personnel.

[0107] For steps S571-S573, after estimating at least one production schedule date of the target product in each production process, the estimated production days required for the target product in the production process are generated based on at least one production schedule date. The estimated production days are then compared with the preset production days threshold. If the estimated production days are greater than or equal to the preset production days threshold, it means that the target product has a risk of overdue production in the production process. At this time, overdue risk warning information is generated and sent to the terminal of the production scheduler, so that the production scheduler can adjust the type and quantity of the target product based on the prompt information, for example, the relevant personnel can reselect some products as target products or modify the number of orders to be produced, etc., to ensure the rationality of the production plan.

[0108] Optionally, the preset production days threshold refers to the upper limit of the production days of the product in each production process, which is used to measure whether the expected production days exceed an acceptable range. The preset production days threshold range can be specifically set according to the production process and the production period, and the preset production days threshold of each production process needs to be less than or equal to the production period.

[0109] It can be seen that in the above scheme, first, based on the product information of the target product to be produced in the production order, the target production line of the target product is formulated to determine the multiple production processes of the target product in the production process, and estimate the processing time of the target product in each production process. Afterwards, the scheduled production data and multiple constraints of the multiple production processes in the production period are obtained, and finally the production plan of the target product is generated based on the target production line, processing time, scheduled production data and multiple constraints. The above technical scheme is adopted to realize automated production scheduling, reduce the dependence on manual labor and workload in the process of production planning, simplify the production scheduling process, and improve the efficiency of production planning. In addition, the production scheduling is realized by combining the processing time of the order with the factory's scheduled production data and constraints, and comprehensively considers factors such as time requirements, resource availability and production capacity in the production process to ensure the feasibility of the production plan and resource utilization.

[0110] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
