[0003] However, the process flow of parts is complicated, resulting in a large workload for manual scheduling. Production schedulers have to spend a lot of time on scheduling every day, and the scheduling results are not easy to transmit. In addition, due to the low efficiency of manual scheduling, the scheduling results cannot be adjusted in time with new orders. The adjustment time is too long, and the adjusted scheduling results cannot be transmitted in time. Summary of the invention

[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0025] Figure 1 is a flow chart of a production scheduling method provided by an embodiment of the present disclosure, and the method can be executed by an electronic device. The electronic device can be exemplarily understood as a device with a page display function such as a mobile phone, a tablet computer, a laptop computer, a desktop computer, a smart TV, etc. Figure 1 As shown, the method provided in this embodiment includes the following steps:
[0026] S110. Obtain a production scheduling model corresponding to the parts in the order, wherein the production scheduling model includes at least one production scheduling route, and the production scheduling route includes at least one node.
[0027] In an embodiment of the present disclosure, the electronic device can obtain a production scheduling model corresponding to a part in an order, so as to subsequently perform standard production scheduling or rolling production scheduling on the parts according to the production scheduling model.
[0028] Specifically, the source of the order may include systems such as enterprise resource planning (ERP), product lifecycle management (PLM), and customer relationship management (CRM), but is not limited thereto.
[0029] Specifically, the types of orders may include customer orders, bill of materials (BOM), orders for self-made parts after production, etc., but are not limited thereto.
[0030] Specifically, an order can be divided into multiple nodes according to its entire life cycle, and the multiple nodes can be sorted according to the production sequence to obtain a production route, which can constitute a production scheduling model.
[0031] For example, Figure 2 Schematic diagram of a production scheduling model provided by an embodiment of the present disclosure. Figure 2 The production scheduling model includes three production scheduling routes, which have both parallel and serial parts. Specifically, the first production scheduling route is "pattern diagram-single-pitch modeling-full circle modeling-pattern block diagram-pattern block process-production-machining transfer-hole introduction-trim-seam repair-perfection-packaging and delivery"; the second production scheduling route is "pattern diagram-single-pitch modeling-full circle modeling-basic mold program-basic mold-casting-production-machining transfer-hole introduction-trim-seam repair-perfection-packaging and delivery"; the third production scheduling route is "pattern diagram-technical department diagram-steel sheet process-casting steel sheet-casting-production-machining transfer-hole introduction-trim-seam repair-perfection-packaging and delivery".
[0032] It can be understood that in the embodiment of the present disclosure, when constructing the production scheduling model corresponding to the parts in the order, all important nodes in the entire life cycle of the order, such as technology and workshop production, are taken into consideration. In this way, the coordination of technology and workshop production can be achieved, which is conducive to production scheduling from the perspective of the enterprise as a whole.
[0033] S120. If the part does not have a current node on any production scheduling route, perform standard production scheduling on the part to obtain the planned start time and planned end time of the part for each node.
[0034] In the disclosed embodiment, if the parts in the order have not started processing, that is, the parts do not have a current node on any production scheduling route, the parts are subjected to standard scheduling to obtain the planned start time and planned end time of the parts for each node.
[0035] Specifically, the current node is the node that has been processed most recently on its production scheduling route.
[0036] Optionally, the process of determining the current node includes: detecting whether the part has an actual completion time for each node; for each production route in the production scheduling model corresponding to the part, taking the last (i.e., the last) node with an actual completion time in the production route in the production sequence as the current node on the production route.
[0037] Specifically, the actual completion time is the time when the node is actually processed and completed.
[0038] Specifically, the total number of production routes in the production scheduling model corresponding to the parts is obtained, and then, for each production route, the nodes on the production route and the production order of the nodes (i.e., detailed production route information) are obtained, and the first node whose actual completion time is not empty is found from bottom to top in the production route according to the production order (i.e., the current node), or the first node whose actual completion time is empty is found from top to bottom, and the previous node of this node is the current node.
[0039] Specifically, standard scheduling uses the difference between the contract duration of the order and the parts batch as the planned duration length corresponding to the part setting, and then uses the standard working time rules corresponding to the planned duration length to schedule each node in the scheduling model.
[0040] In one example, the delivery time of the parts in the order is determined according to the order placement time and the contract duration, and the planned start time and the planned end time of each part in the order for the technical stage, as well as the planned start time and the planned end time of the workshop stage are determined according to the difference between the order placement time, the delivery time and the parts batch, so as to obtain the planned duration length of each part for the technical stage, as well as the planned duration length for the workshop stage. Then, the standard working time rules corresponding to the planned duration length are used for production scheduling to obtain the planned start time and the planned end time of the parts for each node.
[0041] S130. If the part has a current node on at least one production scheduling route, perform rolling scheduling on the part to obtain the planned start time and planned end time of the part for each remaining node, wherein the remaining nodes are nodes located after the current node in the production sequence.
[0042] In the disclosed embodiment, if the parts in the order have started to be processed, that is, the parts have a current node on at least one production scheduling route, the parts are rolled out to obtain the planned start time and planned end time of the parts for each remaining node.
[0043] Specifically, rolling scheduling is to determine the remaining nodes on the production route through the current node on the production route, and determine the remaining duration of the part through the planned completion time of the part for the technical stage and / or the planned completion time for the workshop stage, and the actual completion time of the current node, and then use the standard working time rules corresponding to the remaining duration to schedule the remaining nodes.
[0044] In one example, for each production route, the remaining duration of the part corresponding to the production route is determined based on the planned completion time of the part for the technical stage and / or the planned completion time for the workshop stage, and the actual completion time of the current node on the production route. Then, the remaining nodes on the production route are scheduled using the standard working time rule corresponding to the remaining duration of the part (the remaining duration of the part corresponding to the production route) to obtain the planned start time and end time of each remaining node on the production route.
[0045] It can be understood that the disclosed embodiment is not only suitable for the case of a single production route, but also for the case of multiple production routes, and is not only suitable for the case of single-piece small batch processing, but also for batch processing, and is adaptable to a variety of scenarios. In addition, rolling production is scheduled according to the remaining construction period. Since the current node (i.e., processing progress) is extracted from time to time, the on-site processing can be closer to the production schedule (i.e., the production schedule result), improving the executability of the production schedule.
[0046] The disclosed embodiment can obtain the production scheduling model corresponding to the parts in the order, wherein the production scheduling model includes at least one production scheduling route, and the production scheduling route includes at least one node; if the part does not have a current node on any production scheduling route, the part is subjected to standard production scheduling to obtain the planned start time and planned end time of the part for each node; if the part has a current node on at least one production scheduling route, the part is subjected to rolling production scheduling to obtain the planned start time and planned end time of the part for each remaining node, wherein the remaining nodes are nodes located after the current node in the production sequence. By adopting the above technical scheme, the parts in the order can be automatically subjected to standard production scheduling or rolling production scheduling, saving labor resources and improving production scheduling efficiency. In this way, even if there are new orders, the production scheduling results can be adjusted in time with the new orders, and since the production scheduling results are digital data, it is convenient to transmit them in time through the Internet and other forms, so that production personnel can produce in time according to the production scheduling results.
[0047] In another embodiment of the present disclosure, standard production scheduling is performed on parts to obtain the planned start time and planned end time of the parts for each node, including:
[0048] S121. Determine the planned construction period for the parts according to the technical stage.
[0049] In the disclosed embodiment, the planned construction period of a part includes two parts, namely, the planned construction period for the technical stage (including non-manufacturing nodes such as product design and process design) and the planned construction period for the workshop stage (i.e., workshop production), so as to use the standard working time rules corresponding to the planned construction period for the technical stage to schedule the production of each technical data node belonging to the technical stage, and use the standard working time rules corresponding to the planned construction period for the workshop stage to schedule the production of each process node belonging to the workshop stage.
[0050] Optionally, determining the planned duration of a part for a technical stage includes: selecting the part with the earliest planned end time for the technical stage from the part group to which the part belongs, and using it as the target part, wherein multiple parts in the part group correspond to the same technical data; determining the planned duration of the technical stage based on the planned start time and planned end time of the target part for the technical stage.
[0051] The applicant considers that the product codes and technical data corresponding to the same parts are the same. Since the parts must have complete technical data before entering the workshop stage (for example, the drawings required for processing the parts have been issued), the planned end time of the technical stage for the parts corresponding to the same technical data limits the planned duration of the technical stage. In view of this, when determining the planned duration for the technical stage, the planned end time of each part in the order for the technical stage can be obtained (with the product code as the primary key); the earliest planned end time for the technical stage among all parts corresponding to the same technical data is obtained, and the part corresponding to the earliest planned end time for the technical stage is determined as the target part; the time difference between the planned end time and the planned start time of the target part for the technical stage is calculated to obtain the planned duration of the technical stage.
[0052] S122. Determine the planned duration of each technical data node of the part for the technical stage according to the planned duration of the part for the technical stage and the standard working time table.
[0053] In an embodiment of the present disclosure, a standard working time sheet may be pre-stored in an electronic device, wherein the standard working time sheet records standard working time data corresponding to different planned construction period lengths (planned construction period lengths for technical stages), wherein the standard working time data mentioned here refers to the planned construction period lengths set for each technical data node of the technical stage according to the standard working time rules. In this way, the standard working time sheet may be searched to obtain the standard working time data corresponding to the planned construction period length of the parts for the technical stage.
[0054] Specifically, the technical data node is a node corresponding to the production of technical data.
[0055] Specifically, according to the planned construction period of the part for the technical stage, the corresponding standard working time data in the standard working time table is obtained, and the planned construction period of each technical data node of the part for the technical stage can be obtained.
[0056] In one example, the planned construction period for a part in the technical stage is 9 days, and the first standard working time table obtained by matching records: the planned construction period for technical data node A is from the 1st day to the 3rd day, the planned construction period for technical data node B is from the 4th day to the 5th day, and the planned construction period for technical data node C is from the 6th day to the 9th day.
[0057] S123. Determine the planned start time and the planned end time of the part for each technical data node according to the planned start time of the part for the technical stage and the planned duration of the part for each technical data node.
[0058] In the disclosed embodiment, the order batches corresponding to the same technical data are the same, but the contract durations may be different. Since the same batch of orders may have different contract durations, the planned start time of each part in the order for the technical stage is different, but the planned duration lengths of each technical data node for the technical stage for the parts corresponding to the same technical data are the same. Therefore, for each part in the parts group, the planned start time and planned end time of the part for each technical data node can be determined based on the planned start time of the part for the technical stage and the planned duration length of the part for each technical data node.
[0059] Specifically, the planned start time of the part for the technical stage plus the planned duration length of each technical data node is the planned end time (in days) of each technical data node.
[0060] S124. Determine the planned duration of the parts for the workshop stage.
[0061] Optionally, determining the planned duration of the part for the workshop stage includes: determining the planned duration of the part for the workshop stage according to a planned start time and a planned end time of the part for the workshop stage.
[0062] In the embodiment of the present disclosure, considering that in the actual processing process, the workshop processes in units of parts, each part is unique to the workshop. In view of this, for each part, the time difference between the planned start time and the planned end time of the part for the workshop stage is calculated to obtain the planned duration length of the part for the workshop stage.
[0063] S125. According to the matching of the planned duration of the parts for the workshop stage and the standard working time table, the planned duration of the parts for each process node in the workshop stage is determined.
[0064] In an embodiment of the present disclosure, a standard working time sheet may be pre-stored in an electronic device, wherein the standard working time sheet records standard working time data corresponding to different planned construction period lengths (planned construction period lengths for the workshop stage), wherein the standard working time data referred to here refers to the planned construction period lengths set for each process node in the workshop stage according to the standard working time rules. In this way, the standard working time sheet may be searched to obtain the standard working time data corresponding to the planned construction period length of the parts for the workshop stage.
[0065] Specifically, the process node is the node corresponding to the workshop production.
[0066] Specifically, according to the planned duration of the part in the workshop stage, the corresponding standard working time data in the standard working time table is obtained, and the planned duration of each process node of the part in the workshop stage can be obtained.
[0067] S126. Determine the planned start time and the planned end time of the part for each process node according to the planned start time of the part for the workshop stage and the planned duration of the part for each process node.
[0068] Specifically, the planned start time of the part for the workshop stage plus the planned duration length of each process node is the planned end time (in days) of each workshop process node.
[0069] It can be understood that the above-mentioned method of standard scheduling of parts by technical stage and workshop stage can ensure that the technical data required for processing parts are fully prepared before entering the workshop production, and because the data in the standard time sheet is usually obtained by production personnel based on actual production, the planned construction period of the parts for each node can be determined by querying the standard time sheet, so that the scheduling results can be more in line with the actual production situation.
[0070] In another embodiment of the present disclosure, rolling production scheduling is performed on parts to obtain the planned start time and the planned end time of the parts for each remaining node, including:
[0071] S131. For each production route in the production scheduling model corresponding to the part, determine the remaining duration of the part corresponding to the production route according to the actual completion time of the current node on the production route and the planned completion time of the part.
[0072] In some embodiments, the remaining nodes on the production route include the technical data nodes of the technical stage and the process nodes of the workshop stage, then the planned completion time of the part includes the planned completion time of the part for the technical stage, and the remaining duration of the part corresponding to the production route includes the remaining duration for the technical stage and the remaining duration for the workshop stage, wherein the remaining duration for the technical stage can be obtained by calculating the difference between the actual completion time of the current node and the planned completion time of the part for the technical stage, and the planned duration of the part for the workshop stage is the remaining duration for the workshop stage.
[0073] In some embodiments, the remaining nodes on the production route only include process nodes of the workshop stage, then the planned completion time of the part includes the planned completion time of the part for the workshop stage, and the remaining duration of the part corresponding to the production route only includes the remaining duration for the workshop stage, wherein the remaining duration for the technical stage can be obtained by calculating the difference between the actual completion time of the current node and the planned completion time of the part for the workshop stage.
[0074] S132. Determine the planned start time and the planned end time of each remaining node according to the remaining duration of the parts corresponding to the production route, the rolling timetable and the standard timetable.
[0075] In some embodiments, the remaining duration of the part corresponding to the production route includes the remaining duration for the technical stage and the remaining duration for the workshop stage. Then, scheduling the remaining nodes in the production route includes: scheduling the remaining nodes of the technical stage according to the remaining duration of the part for the technical stage; scheduling the remaining nodes of the workshop stage according to the remaining duration of the part for the workshop stage (similar to S124-S126, which will not be repeated here).
[0076] In other embodiments, the remaining duration of the part corresponding to the production route only includes the remaining duration for the workshop stage, and scheduling the remaining nodes in the production route includes: scheduling the remaining nodes of the technical workshop stage according to the remaining duration of the part for the workshop stage.
[0077] Specifically, the process of scheduling the remaining nodes (whether they are the remaining nodes in the technical stage or the workshop stage) according to the remaining duration is as follows: search for the data corresponding to the remaining duration in the rolling duration table (i.e., rolling duration data); obtain the duration length in the rolling duration data; according to the duration length, obtain the standard duration data corresponding to the duration length in the standard duration table (i.e., the planned duration length corresponding to the remaining nodes); take the actual completion time of the current node as the starting time, and calculate the planned start time and planned completion time of the remaining nodes according to the standard duration data. It should be understood by those skilled in the art that no production scheduling is made for the nodes before the current node.
[0078] Optionally, the method further includes: S133, if the remaining nodes are located in multiple production scheduling routes, selecting the latest planned end time from multiple planned end times obtained by the standard production scheduling of the remaining nodes as the planned end time of the remaining nodes.
[0079] In one example, see Figure 2 When the remaining nodes include the casting node and its subsequent nodes, since these nodes are located in three production scheduling routes, the same node will have three planned completion times. The latest planned completion time among all planned completion times is used as the final planned completion time of the node, and the shortest remaining duration in each production scheduling route is used as the final remaining duration.
[0080] Optionally, the method also includes: in the case where a certain node has not been completed, the planned completion time calculated according to the standard working hours may be earlier than the current production scheduling time (ie, the current time), then the planned completion time of the node is uniformly changed to the current production scheduling time.
[0081] It is understandable that, since the data in the rolling timesheet and the standard timesheet are usually obtained by production personnel based on actual production, the production scheduling results can be made more consistent with the actual production situation by looking up the rolling timesheet and the standard timesheet to determine the planned duration of the parts for each remaining node. In addition, the latest planned completion time among multiple planned completion times corresponding to the same remaining node is used as the final planned completion time of the remaining node, so that the planned completion time of the remaining node is more consistent with the actual production situation.
[0082] In another embodiment of the present disclosure, the method further includes:
[0083] S140. Determine the current remaining capacity and current load corresponding to the first preset node.
[0084] Specifically, the first preset node refers to any node that needs to be processed within the time period from the current production scheduling time (ie, the current moment) to the preset moment.
[0085] Specifically, the current remaining capacity refers to the capacity in the time period from the current production schedule (ie, current moment) corresponding to the first preset node to the preset moment. The current load refers to the load in the time period from the current production schedule corresponding to the first preset node to the preset moment.
[0086] Optionally, the current remaining capacity may be the remaining capacity for the day, and the current load may be the remaining load for the day.
[0087] Specifically, the process of determining the remaining production capacity for the day corresponding to the first preset node can be as follows: obtain all working time periods (start time and end time) of the first preset node and schedule them according to the start time; if the current scheduling time is earlier than or equal to the earliest start time of all working time periods of the first preset node, it indicates that at the current scheduling time, this first preset node is about to go to work, and the remaining production capacity for the day is equal to the total production capacity for the day; if the current scheduling time is later than or equal to the latest end time of all working time periods of the first preset node, it indicates that at the current scheduling time, this first preset node is in an off-duty state and can no longer be assigned tasks, and the remaining capacity is 0; if the current scheduling time is within a working time period of the first preset node, the used capacity of the first preset node = (used working time / total time of the first preset node) * total capacity of the first preset node, and the remaining capacity of the first preset node = total capacity of the first preset node - used capacity of the first preset node.
[0088] S150. If the current remaining capacity is greater than the current load, search for parts that meet the preset activation conditions as activation parts, and activate the parts in advance according to the planned start time and the planned end time of the first preset node.
[0089] Optionally, the preset activation condition is the highest scheduling level and / or the earliest planned completion time of the part for the workshop stage.
[0090] In one example, when the capacity of the first preset node is insufficient on a certain day (i.e., the current remaining capacity is greater than the current load), starting from the second day, parts that can be activated (i.e., parts that meet the preset activation conditions) are searched, where the search conditions are that the parts with the earliest planned completion time for the workshop stage and / or the parts with the highest scheduling level are prioritized. It should be noted that after the planned completion time of the first preset node is advanced, it cannot be earlier than the planned completion time of the previous node. For example, when the pattern is activated, the planned start time after advancement cannot be earlier than the planned start time of the part.
[0091] Optionally, after the first preset node is processed in advance, its subsequent nodes may not be processed.
[0092] It is understandable that the imbalance of receiving orders will lead to uneven load in the workshop, and it is easy for nodes to complete processing ahead of the corresponding production scheduling time, resulting in waste of production capacity. In the embodiment of the present disclosure, by performing activation processing when the current remaining capacity is greater than the current load, the production capacity can be fully utilized.
[0093] In another embodiment of the present disclosure, the method further comprises:
[0094] S160. Count the load corresponding to the second preset node on the preset date according to the production scheduling results of all parts.
[0095] Specifically, the production scheduling result of a part is the planned start time and planned end time of a node obtained after standard scheduling or rolling scheduling of the part.
[0096] Specifically, the second preset node refers to any node that needs to be processed within a preset date.
[0097] Specifically, the preset date may be the day of the current production schedule, or any day after the current day.
[0098] In one example, the planned completion time of each part for each node is found, the parts are grouped according to the planned completion time, and the load of the second preset node of each day is counted.
[0099] S170. If the production capacity corresponding to the second preset node on the preset date is less than the load corresponding to the second preset node on the preset date, find a part that meets the preset capacity constraint condition as the capacity constraint part, and postpone the planned start time and planned end time of the capacity constraint node of the capacity constraint part, wherein the capacity constraint node is the second preset node and the node located after the second preset node in the production order.
[0100] Optionally, the preset capacity constraint condition is that the production scheduling level is the lowest and / or the planned completion time of the parts for the workshop phase is the latest.
[0101] In one example, for each second preset node that needs to be processed on a preset date, if the capacity of the second preset node on the preset date is less than the load on the preset date, the node planned completion time is postponed (i.e., capacity constraint processing). Specifically, if the capacity of the second preset node on the preset date is less than the load on the preset date, all product code information corresponding to the day when the capacity is exceeded is found, and all product codes are sorted according to the earliest planned completion time of all parts under them. The parts that exceed the capacity have a later planned completion time or a lower production scheduling level, and the planned completion time of the second preset node and subsequent nodes of the part can be postponed, and the second preset node is postponed for one day, and the subsequent nodes (determined according to the production scheduling route where the second preset node is located) are postponed with reference to the rolling production scheduling rules. If the time difference between the two nodes before and after the standard working time is 0, the subsequent node postponement time shall be based on the previous node. It should be noted that if there are multiple planned completion times for a node (such as casting and subsequent nodes), the latest planned completion time among multiple production scheduling routes is used as the basis for node capacity constraint.
[0102] It is understandable that through capacity constraint processing, the production scheduling results can be matched with the actual capacity, which can not only fully utilize the capacity but also reduce the risk that the actual capacity cannot afford the production scheduling plan.
[0103] Of course, the method may also include: holiday maintenance, that is, if there is a holiday between the planned start time and the planned end time of the node, the planned end time may be postponed according to the number of holidays. In this way, the production scheduling result can be more in line with the actual holiday situation.
