All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The core of the application is to provide a scheduling system, a device, a method and a medium, and the technical scheme considers the association between orders, so that the orders can be arranged in advance or arranged later, the productivity and the load of the scheduling node are balanced, and the utilization rate of a production line can be improved.
In the present application, the hardware includes a computer device, for example, a computer device disposed in a production line machine room, and performs data interaction with an external computer device, for example, obtains an order sent by the external computer device, parses relevant data useful for scheduling from the order, and performs scheduling, specifically, performs scheduling according to a scheduling method hereinafter. In addition, the computer equipment corresponding to each production line forms a local area network so as to send the related scheduling plan of each production line to the computer equipment corresponding to each production line. Because the orders are uniformly sent to the same computer equipment, the computer equipment uniformly processes all the orders, so that the orders are not only mutually related, but also can be advanced or pushed back according to the actual conditions of all the production scheduling nodes, thereby balancing the productivity and the load of all the production scheduling nodes and improving the utilization rate of the production line.
In order to make the relevant terms mentioned below more apparent to those skilled in the art, the following explanation is made herein:
a scheduling node (also referred to as a node) refers to a minimum unit of scheduling;

the load refers to a work task which is scheduled to be distributed by the scheduling node every day;

In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
Fig. 1 is a block diagram of a scheduling system according to an embodiment of the present application. As shown in fig. 1, from the perspective of functional modules, corresponding functions may be implemented by a computer device, a scheduling system comprising:
and the acquisition module 1 is used for acquiring the theoretical capacity of the target production scheduling node and the planned load of the target production scheduling node on the same day.
It should be noted that, the target scheduling node mentioned in the present application is any one scheduling node, and not specifically, for example, there are 10 scheduling nodes, so when scheduling the scheduling node 1, the scheduling node 1 is the target scheduling node, and similarly, when scheduling other scheduling nodes, the other nodes are the target scheduling nodes.
In a specific implementation, each production scheduling node has its theoretical capacity, that is, how many products can be theoretically produced in one day, for example, the theoretical capacity is that 10 products are produced by the production scheduling node 1. In general, the theoretical capacity of different scheduling nodes is different, and even the theoretical capacity may change in different production lines or under different working conditions, and the data may be obtained through a manufacturing process card or other ways, which is not limited in this embodiment.
The planned load of the target production node on the same day refers to a task that is planned to be allocated to a certain production node on a certain day, for example, a processing task that is planned to allocate 8 products to the production node 1.
It is particularly pointed out that the theoretical capacity for the target production scheduling node and the planned load on the day of the target production scheduling node must be the same target production scheduling node for making sense, for example the above-mentioned production scheduling node 1, and that both the theoretical capacity and the planned load on the day are for the production scheduling node 1.
It is obvious that if the theoretical capacity of the target scheduling node is the same as or similar to the planned load of the target scheduling node on the same day, the scheduling node can realize capacity and load balance, but once the theoretical capacity of the target scheduling node and the planned load of the target scheduling node on the same day are very different, the target scheduling node inevitably has a large number of idle or overload running problems.
And the comparison module 2 is used for comparing the relation between the theoretical capacity of the target production scheduling node and the planned load of the target production scheduling node on the same day.
The comparison module 2 compares the relation between the theoretical capacity of the target production scheduling node and the planned load of the target production scheduling node on the same day to determine whether the current target production scheduling node has a large amount of idle or overload operation. For example, the theoretical capacity of the scheduling node 1 is 10, the planned load on the same day is 8, the planned load on the same day of the target scheduling node is smaller than the theoretical capacity of the target scheduling node, the theoretical capacity of the scheduling node 1 is 10, the planned load on the same day is 12, and the planned load on the same day of the target scheduling node is larger than the theoretical capacity of the target scheduling node.
And the first screening module 3 is configured to screen a first target order from the orders after the current day according to the first deviation if the current day planned load of the target scheduling node is smaller than the theoretical capacity of the target scheduling node, and allocate the task of the first target order to the current day plan of the target scheduling node.
It will be appreciated that since all orders can be acquired, the orders are interrelated, so there is additional capacity on the day of identifying the target scheduling node, and it is necessary to advance some of the orders to the day. In addition, the order to be advanced must include the target scheduling node in the corresponding scheduling node because the target scheduling node is scheduled. In practice, there are typically many such orders to satisfy, so an order from these orders that matches the first deviation is selected, referred to herein as the first target order. It should be noted that the first target order may be 1 order, or may be a plurality of orders, which is mainly determined according to the first deviation. The first deviation is a difference between the planned load of the target production scheduling node on the same day and the theoretical capacity of the target production scheduling node, for example, the planned load of the target production scheduling node on the same day is 8, the theoretical capacity of the target production scheduling node is 10, the first deviation is 2, and the first target order may be 1, or 2, or not more than 2. Therefore, the output can be as much as possible within the capacity range of the target production scheduling node, so that the utilization rate of the production line is improved, the planned load of the target production scheduling node in a certain day is prevented from being too large, and the production line balance is realized.
And the second screening module 4 is configured to screen a second target order from the current planned load according to the second deviation if the current planned load of the target scheduling node is greater than the theoretical capacity of the target scheduling node, and allocate the task of the second target order to the current plan of the target scheduling node.
It will be appreciated that since all orders can be acquired, the orders are interrelated, so that the planned load on the day of validation of the target production node is beyond the theoretical generation capacity, then part of the orders need to be pushed back. In practice, there are typically many such orders to satisfy, so an order from these orders that matches a second deviation, referred to herein as a second target order, is selected. It should be noted that the second target order may be 1 order, or may be a plurality of orders, which is mainly determined according to the second deviation. The second deviation is a difference between the planned load of the target production scheduling node on the same day and the theoretical capacity of the target production scheduling node, for example, the planned load of the target production scheduling node on the same day is 12, the theoretical capacity of the target production scheduling node is 10, the second deviation is 2, and the first target order may be 2 or more. Therefore, the problem that the planned load of the target production scheduling node is too large in a certain day and the planned load of the target production scheduling node is extremely small in a certain day is avoided, so that the utilization rate of the production line is improved, and the production line balance is realized.
The scheduling system provided in this embodiment includes: the system comprises an acquisition module, a comparison module, a first screening module and a second screening module, wherein the relation between the theoretical capacity of a target production scheduling node and the planned load of the target production scheduling node on the same day can be compared, and when the planned load of the target production scheduling node on the same day is smaller than the theoretical capacity of the target production scheduling node, a first target order is screened out from orders after the same day according to a first deviation, and the task of the first target order is distributed to the current day plan of the target production scheduling node; and under the condition that the current planned load of the target scheduling node is larger than the theoretical capacity of the target scheduling node, screening a second target order from the current planned load according to the second deviation, and distributing the task of the second target order to the current plan of the target scheduling node. Therefore, according to the scheme, on one hand, the relevance among orders is considered, the advancing or pushing of each order can be dynamically distributed according to the theoretical capacity of the target scheduling node, on the other hand, the advancing or pushing quantity of the orders is determined according to the first deviation and the second deviation, artificial experience determination is avoided, more products can be produced within the capacity range of the target scheduling node, too large planned load of the target scheduling node in a certain day can be avoided, and production line balance is realized, so that the utilization rate of the production line is improved.
Fig. 2 is a block diagram of another production scheduling system according to an embodiment of the present application. As shown in fig. 2, in one embodiment, the first screening module 3 includes:
a first determining unit 30 for determining a first deviation according to the theoretical capacity of the target production scheduling node and the planned load of the target production scheduling node on the same day;
the forward ordering unit 31 is configured to perform forward ordering on orders after the target scheduling node according to the order construction period to obtain a forward ordering result;
a first selecting unit 32, configured to select, from the forward ordering result, an order with the earliest construction period and a current residual load not more than the first deviation as a first target order;
the first allocation module 33 is configured to allocate the task of the first target order to the current day plan of the target scheduling node.
In the above embodiment, it is mentioned that there may be a plurality of orders meeting the requirement, and how to select the first target order from the plurality of orders is a key factor for reasonably distributing the capacity and balancing the production line. For example, all of the production nodes of the order 1, the order 2, the order 3, the order 4, the order 5 and the order 6 have target production nodes, and the order construction period is sequentially pushed back, and then the forward sequencing result is the order 1, the order 2, the order 3, the order 4, the order 5 and the order 6. If the first deviation is 2, 2 orders are selected from the forward sequencing result, and the construction period is earliest, namely, the order 2 and the order 3 are first target orders, and the order 4, the order 5 and the order 6 are not advanced in the current scheduling. The order mentioned herein with earliest construction period and no more current residual load than the first deviation is the order selected to advance earliest and the total number of loads is no more than the order of the first deviation. For example, the orders to advance are order 2 and order 3, i.e., the first target order includes order 2 and order 3, the load of order 2 is 1, the load of order 3 is 1, then the current remaining load is 2. Table 1 is the change in order ahead of time, both before and after delivery. In table 1, since 9.1 days are the day, only the day of 9.1 days is scheduled.
TABLE 1
In this embodiment, by selecting the order with the earliest order from the orders according to the order period as the first target order in the orders meeting the requirements, the later order can be prevented from advancing. Since other scheduling nodes of a later order have not yet started scheduling, advancing the order has little significance for improving production efficiency.
As shown in fig. 2, in one embodiment, the second screening module 4 includes:
a second determining unit 40 for determining a second deviation according to the theoretical capacity of the target production scheduling node and the planned load of the target production scheduling node on the same day;
the negative ordering unit 41 is configured to perform negative ordering on the orders on the current day of the target scheduling node according to the order construction period to obtain a negative ordering result;
a second selecting unit 42, configured to select, from the negative ordering results, an order with the latest construction period and a current residual load not less than a second deviation as a second target order;
a second allocation module 43 for allocating tasks of the second target order to the next day plan of the target scheduling node.
In the above embodiment, it is mentioned that there may be a plurality of orders meeting the requirement, and how to select the second target order from the plurality of orders is a key factor for reasonably distributing the capacity and balancing the production line. For example, all of the scheduling nodes of order 1, order 2, order 3, order 4, order 5 and order 6 have target scheduling nodes, and the order construction period is sequentially pushed back, the tasks on 9.1 days of the day include order 1, order 2 and order 3, so that the planned load of the target scheduling nodes is 3, and if the theoretical load is 2, the second deviation is 1. And (3) carrying out negative sorting on the order construction period of the target scheduling node on the same day, wherein the negative sorting results are the order 3, the order 2 and the order 1. And selecting 1 order from the negative ordering results according to the second deviation, wherein the time limit is the latest, namely order 3, then order 3 is the second target order, and orders 1, 2 cannot be pushed back in the current scheduling. The order whose construction period is the latest and whose current residual load is not less than the second deviation is referred to herein as the order whose construction period is the latest to be pushed, and whose total load is not less than the second deviation. For example, order 3 is later than order 2 in terms of construction, and the current residual load of order 3 is not less than the second deviation, so order 3 can be the second target order. Table 2 shows the changes of the order before and after delivery, after the order was pushed. In table 2, since 9.1 days are the day, only the day of 9.1 days is scheduled.
TABLE 2
In this embodiment, by selecting, from among the orders satisfying the requirement, the order with the latest order period as the second target order according to the order period, the earlier order can be avoided from being pushed back. Because earlier orders are pushed, it is possible to influence the scheduling of other scheduling nodes of the order (in principle the period of one scheduling node cannot be earlier than the period of the upstream scheduling node).
Fig. 3 is a block diagram of still another scheduling system according to an embodiment of the present application. As shown in fig. 3, in one embodiment, the first selecting unit 32 includes:
a first selecting subunit 320, configured to select, from the forward ordering results, an order with the earliest construction period from the remaining orders;
a first obtaining subunit 321, configured to obtain each scheduling node corresponding to the currently selected order;
a first determining subunit 322, configured to determine, from among the production nodes, a preamble node of the target production node;
a second obtaining subunit 323, configured to obtain a time for completing a construction period of the preamble node;
a first judging subunit 324, configured to judge whether the time for completing the construction period of the preamble node is no later than the current day, trigger the rejecting subunit 325 if the time is no later than the current day, and trigger the second determining subunit 326 if the time is no later than the current day;
A rejecting subunit 325, configured to reject the currently selected order from the forward ordering result, and trigger the first selecting subunit 320;
a second determining subunit 326, configured to determine the currently selected order as the first target order, and trigger a second judging subunit 327;
a second judging subunit 328, configured to judge whether the total load of the first target order is smaller than the first deviation, reject the currently selected order if the total load is smaller than the first deviation, trigger the first selecting subunit 320 to continue the selection, and trigger the first distributing module 33 if the total load is not smaller than the first deviation.
In practice, an important condition is that the date of the target production node in the order being advanced cannot be earlier than the date of its lead production node. This is because the production nodes are in a definite order, for example, the production node 1 is processed before the production node 2 can be processed, so that it is meaningless if the schedule of the subsequent production node is earlier than the schedule of the preceding production node. The total load of the first target order referred to herein is the total number of loads of the selected orders to be advanced, e.g., order 2 and order 3, i.e., the first target order includes order 2 and order 3, the load of order 2 is 1, the load of order 3 is 1, then the current remaining load of the first target order is 2.
Examples: the daily theoretical capacity of the scheduling node 1 is 10, and the planning range of the scheduling node 1 obtained by theoretical scheduling is 9.1 days to 9.15 days. If the planned load of the scheduling node 1 on 9.1 days is 8 and the planned load is smaller than the theoretical capacity, one order is selected from the current rest orders from 9.2 days, whether the order can become a first target order is verified, and if so, the next earliest order in the construction period is continuously verified until the number of the orders and the first deviation are equal. It should be noted that, in this embodiment, the first selecting subunit 320 is configured to select, from the forward ordering result, an order with the earliest construction period from the remaining orders, where, for the first selection, the remaining orders are all orders, and if the remaining orders are selected for the second time, the remaining orders are orders except the removed or selected order, and no repeated selection is performed.
For example, starting on 9.2 days, the rest orders are order 9, order 10, order 11, order 12 and order 13 respectively, and the order construction period is sequentially from the morning to the evening, then when the order is selected for the first time, the order 9 is selected, if the construction period of the front node of the order 9 is not later than the day, the currently selected order is determined, that is, the order 9 is taken as the first target order, one order is selected at this time, and the first deviation is not equal, so that the next selection is performed, when the rest orders are order 10, order 11, order 12 and order 13 respectively, then when the order is selected for the second time, the order 10 is selected, if the construction period of the front node of the order 10 is not later than the day, the currently selected order is determined, that is, the order 10 is taken as the first target order, 2 orders are selected at this time, and the first deviation is equal, so that the first allocation module 33 is directly triggered.
For example, starting on 9.2 days, the rest orders are order 9, order 10, order 11, order 12 and order 13 respectively, and the order construction period is from the early to the late, then when the order is selected for the first time, the order 9 is selected, if the construction period completion time of the front node of the order 9 is later than the day, the currently selected order is determined to be removed, the order 9 is to be selected and the next selection is performed, at this time, the rest orders are order 10, order 11, order 12 and order 13 respectively, when the order is selected for the second time, the order 10 is selected, if the construction period completion time of the front node of the order 10 is not later than the day, the currently selected order is determined to be the first target order, at this time, 1 order is selected and the first deviation is not equal, so the next selection is performed, at this time, the rest orders are order 11 is selected when the order 11 is selected for the second time, if the construction period completion time of the front node of the order 11 is not later than the day, the currently selected order 11 is determined to be the first target order 11, the first deviation is selected, and the first deviation is directly equal, and the first deviation is directly allocated, and the first deviation is triggered, 33.
In the embodiment, when the order needs to be advanced, the date of the lead node corresponding to the order is judged to ensure that the date of the target production scheduling node of the advanced order is not earlier than the plan of the lead node.
In a specific implementation, in order to avoid frequent changes of the scheduling plan of the target scheduling node, two constraint conditions are introduced when the scheduling node plan is advanced: the time coefficient and the productivity coefficient are described in detail below.
On the basis of the above embodiment, as shown in fig. 3, the scheduling system further includes a processing module 5, and the processing module 5 includes:
a third determining unit 50, configured to determine an actual planning period of the target production node corresponding to the first target order;
a first obtaining unit 51 for obtaining a time coefficient for restricting the allowable advance of the production node;
a fourth determining unit 52, configured to determine a maximum number of days in advance of the target scheduling node according to the time coefficient;
a fifth determining unit 53 for determining the earliest date of advance based on the actual planned construction period and the most advanced days;
a first judging unit 54 for judging whether the current day is earlier than the earliest date in advance, if so, triggering the sixth determining unit 55, and if not, triggering the first distributing module 33;
The sixth determining unit 55 is configured to determine that the target scheduling node of the corresponding order does not need to be advanced.
In this embodiment, the time coefficient acts to constrain the maximum margin that the target production node is allowed to advance. The time coefficient can ensure the shortest period of the production node processing due to the time required for the production node processing. The current scheduling results are only specific to the day, so that a certain scheduling node may finish processing in the morning or evening of the day, if processing is finished in the evening, the subsequent node will not normally proceed immediately, and some preparation time is required before the scheduling node processes.
If the schedule of the scheduling node 1 is 9.1 days, the schedule of the scheduling node 2 is 9.11, and the scheduling node 2 is processed in advance, and the time coefficient is set to 0.8, the scheduling node 2 can be limited to 10×0.8=8 days in advance, that is, the scheduling node 2 can be advanced by 8 days at maximum, that is, the earliest time can be advanced by 9.3 days.
In this embodiment, by setting the time coefficient, it is ensured that the date of the order to be advanced is not too early compared with the theoretical date of production, so as not to affect the premature production of the product and the product cannot be utilized.
On the basis of the above embodiment, as shown in fig. 3, the production scheduling system further includes a processing module 5, where the processing module 5 includes:
A second obtaining unit 56, configured to obtain a capacity coefficient for restricting a production scheduling node to be in advance;
a seventh determining unit 57 for determining a critical load of the target production node according to the productivity coefficient and the theoretical productivity;
a second judging unit 58 for judging whether the planned load of the target production scheduling node on the same day is smaller than a critical load; if yes, triggering a first determining unit, and if no, triggering an eighth determining unit;
the eighth determining unit 59 is configured to determine that the target scheduling node of the corresponding order does not need to be advanced.
In this embodiment, the capacity factor is used to constrain whether the production node needs the maximum limit of advance. If the theoretical capacity of the scheduling node 2 is 10, the planned load is 8, and the capacity coefficient is 0.8, the minimum load for the scheduling node 2 to start the planned advanced treatment is 10×0.8=8, i.e., the critical load mentioned in this embodiment, that is, the planned load of the scheduling node 2 is less than 8, the advanced treatment is performed, and the planned load is between 8 and 10, the advanced treatment may not be performed.
In an implementation, the capacity coefficient may be freely set according to the user, and may be set to a coefficient value of < 1 if the order volume is small, and may be set to a coefficient value of > 1 if the order volume is full. That is, the critical load may be less than or greater than the theoretical capacity.
In this embodiment, by setting the capacity coefficient, a small adjustment space for the capacity of the target scheduling node can be ensured, frequent adjustment of orders is avoided, and stability of the scheduling plan is facilitated.
On the basis of the above embodiment, in this embodiment, the scheduling system further includes:
the recording module is used for recording the related information of the first target order in advance and the related information of the second target order in delay.
In implementations, the information related to the advancement of the first target order may include an order number, a specific date of advancement. Similarly, the information related to the advance of the second target order may also include an order number, a specific date that is delayed. And recording the related information of the first target order in advance and the related information of the second target order in delay through a recording module so as to facilitate subsequent tracing.
