Detailed Description
The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention.
As shown in fig. 1-7, the present invention provides a profile extrusion production scheduling method, which comprises the following steps:
s100) receiving the production scheduling request, analyzing the production scheduling request, and grouping orders to obtain a target production plan. The target production plan is an order group grouped according to a producible workshop or a product line and a delivery date of customer requirements.
The method specifically comprises the following steps:
s110) obtaining the customer requirements.
S120) determining the production platform and the equipment number of the workshop to obtain the production capacity of the workshop.
S130) according to the customer requirements and the production capacity of the production workshop, grouping the orders into branch orders and public orders.
Firstly, according to the client requirements and the production capacity of the production workshop, the specific product orders of the workshop A and the workshop B are separated, and whether the production is carried out in the workshop A or the workshop B is determined. Both shop A and shop B can be produced and treated as a common order.
And (3) grouping the client orders of the workshop A after the order division according to the corresponding relation between the workshop production line and the products, and referring to the table 1.
TABLE 1
| Workshop | Production line | Product(s) |
| A workshop | 001 | XXXX |
| A workshop | 001 | XXXX |
| A workshop | 002 | XXXX |
The independent orders from the branch are grouped according to the delivery order sequence requested by the customer, see table 2.
TABLE 2
| Order form | Workshop | Delivery date (sky) | Product(s) | Pre-scheduling group identification |
| 001 | A workshop | 2020-1-20 | XXXX | 001 |
| 002 | A workshop | 2020-1-20 | XXXX | 001 |
| 004 | B workshop | 2020-1-20 | XXXX | 001 |
| 005 | B workshop | 2020-1-20 | XXXX | 001 |
The public orders are grouped in order of delivery, see table 3.
TABLE 3
| Order form | Delivery date (sky) | Product(s) | Pre-scheduling group identification |
| 001 | 2020-1-20 | XXXX | 001 |
| 002 | 2020-1-20 | XXXX | 001 |
| 004 | 2020-1-20 | XXXX | 001 |
| 005 | 2020-1-20 | XXXX | 001 |
The pre-arranged group mark of the order is strictly compiled according to the delivery date requirement required by the client, and the group mark number can be directly expressed by date.
Specifically, the grouping is carried out in a diversified way according to different customer requirements.
S200) calling a target constraint mechanism corresponding to the target production plan, wherein the target constraint mechanism comprises an order sequence rule and a resource load balancing principle. If the corresponding relationship between each production plan and each constraint mechanism can be pre-stored on the platform, after the target production plan is obtained through analysis, the target constraint mechanism corresponding to the target production plan can be called, and the scheduling scheme of each preset version can be generated based on the target constraint mechanism. The constraint mechanism can also comprise material demand planning, workshop production line and equipment task sequence and the like.
S300) pre-scheduling, determining order priority and production platform equipment priority, and matching production platform equipment for the order.
The method specifically comprises the following steps:
s310) determining the grouped order priority according to the order plan type. The batches are first divided according to the order plan type, and can be divided into reserve plan order batches, full order batches and general order batches, for example. Calculating order priority in each order batch; the smaller the order quantity, the higher the priority; the higher the priority of the less required auxiliary equipment; if there is a customer ranking, the higher the customer ranking, the higher its corresponding order priority, and if not, ignore.
S320) the orders are pre-scheduled according to the priority, combinations of the equipment and the molds are searched, when more than one combination of the equipment and the molds exists, the priority is judged according to the load degree of the combination of the equipment and the molds, and the smaller the load degree is, the higher the priority is.
Firstly, the orders are arranged according to the grouping and the sequence of the delivery date required by the client, the orders are searched according to the date of the delivery date, and the orders of the next delivery date are arranged after the orders of the delivery date on the same day are arranged. The corresponding equipment and mould are searched from the product of the first order according to the order priority, if more than one combination of equipment and mould can be found (provided that the current state of the mould and equipment is normal, non-damaged, non-fault maintenance and non-overhaul), the current load (the load is the service time to which the load is ranked, the time that the load is least occupied is smaller than the current time) is smaller according to the priority, the priority is higher, and if no load is available, the priority is highest.
If a plurality of unloaded molds and equipment are found, their future most recent maintenance/shutdown plans are expected to be of higher priority the farther from the current time. According to the priority, the planned completion time of the order between the equipment and the mould is calculated through the order quantity and the traction speed of the corresponding equipment, the occupied time (load) of the equipment and the mould is recorded, and if the equipment planning time exists in the period, the planned completion time is added to the planned time interval of the equipment. And judging whether the load exceeds the delivery date or not, and if not, storing the result.
S330) when the found combination of the equipment and the mould can still produce other orders in the delivery date after matching the current order, searching the matched order for the combination of the equipment and the mould according to the resource load balancing principle until the delivery date is exceeded after a certain order is discharged, or when no order can be discharged, and the production scheduling result of the order is not stored after the order exceeding the delivery date is discharged.
And searching order rules and determining a production strategy. The order rule is searched according to the sequence of the production strategy: 1. the same color as the product; 2. different colors are obtained from the same product; 3. the same group of products (a group of products which have different thickness specifications and can be switched without changing the die) have the same color; 4. changing white in the same mode; 5. exchanging other colors in the same mode; 6. and (5) changing the mould varieties. When the orders grouped by the same delivery date do not meet 1 and 2 and need to meet continuous requirements through strategies in 3, 4, 5 and 6, the orders are not continuously arranged on the equipment, other moulds and equipment are firstly searched for production, and when the orders cannot be matched, the orders are arranged on the original equipment and moulds through the strategies above 3.
And according to the production strategy, according to the priority of the branch order and the priority of the production platform equipment, high-priority is matched, scheduling is carried out, and the branch order is completely discharged. After the strategy is matched, before the order is scheduled, the starting time needs to judge that color changing and mold changing exist, the color changing time is increased on the basis of equipment load when the color is changed, and the starting time is the mold changing time after the mold changing time is increased on the basis of the equipment load when the mold is changed. Before each step of continuous production strategy, a branch order must be found first, and when the unique order does not satisfy the strategy, a public order is found, and when the public order does not satisfy, the next strategy is changed.
In order to ensure the production continuity, after the equipment mold combination is found for an order with high priority, the matched order is found for the equipment mold combination with production allowance until other orders cannot be completed, and the production strategy is used for finding the matched order for the equipment mold combination.
As shown in fig. 5, matching between the orders and the production platform equipment is performed to pre-schedule the orders, and when platform 2 has equipment to be filled, and the subsequent orders continue to be scheduled, platform 2 continues to be scheduled with the lowest priority. After finding the platform corresponding to the next platform, the scheduling principle is consistent with the first platform principle. And after the second platform finishes the ranking, the logic required by the platform priority of the subsequent order matching for the next time is compared with the logic of the first matching priority. On the basis of the previous logic, the judgment after the module change is added, as long as the module change exists, the priority is backward, the more the module change times are, and the lower the priority is. And so on until all selected orders are exhausted.
S340) judging the load degree of the combination of the apparatus and the mold and recording. This is in preparation for the next determination of the priority of the apparatus and mold combination.
Repeating steps S320 and S340 completes the pre-scheduling of all orders.
S400) production scheduling is carried out for production in a period of scheduling time after the current time, order priority in the production scheduling is determined, the production scheduling is matched with production platform equipment, and a scheduling result is locked. The production schedule is divided into a lockable production schedule for the first three days in the future and a dynamic schedule for the fourth day, and the processes of the production schedule and the dynamic schedule are similar to the order schedule process.
The method specifically comprises the following steps:
s410) determining a delivery date of the production schedule, wherein the delivery date is a response delivery date and is not a customer request delivery date; the response lead time is compared with a lead time for which the customer requires the lead time to leave sufficient response time for processing when a production failure occurs or the quantity of nonconforming exceeds the expectation;
s420) determining the priority of the order in the production schedule according to the user type, wherein the determination mode is the same as that of the step S310;
s430) carrying out production scheduling on the production scheduling order according to the priority, searching the combination of equipment and a mould, and judging the priority according to the load degree of the combination of the equipment and the mould when more than one combination of the equipment and the mould is used, wherein the smaller the load degree is, the higher the priority is;
s440) when the found combination of the equipment and the mould can still produce other orders in the delivery date after matching the current order, searching matched orders for the combination of the equipment and the mould according to the resource load balancing principle until the orders which can be completed in the delivery date cannot be found;
s450) judging and recording the load degree of the combination of the equipment and the mould;
repeating the steps S420 and S450 to complete the production schedule of all the grouped orders, wherein the order quantity of the production schedule is the total order quantity-the order reporting quantity, and the order reporting quantity is the quantity of the finished part of the schedule which is qualified.
Note that the priority of the production schedule cannot be mixed with the priority of the order, and needs to be recalculated, and different from the pre-scheduling action, after each order is scheduled, if the time period of the mold change is 0 to 8 points, the scheduling result of the order is not saved, other platforms and equipment are searched, and when the order cannot be satisfied by finding other equipment, the scheduling result of the order is saved. But the order quantity is not the current order quantity, but the order margin, which is the order quantity-order remittance quantity. The sales order needed to be produced automatically generates a production order list to prepare production schedule. The production order form must have: scheduled start time, scheduled finish time, customer requested delivery date, response delivery date, order quantity, scheduled quantity, remitted quantity, qualified quantity, unqualified quantity, and residual quantity (order quantity-production scheduled quantity + unqualified quantity).
The step also includes rearrangement, the rearrangement is provided that all orders in the scheduling time of the previous three days are not locked (if the plan of the previous three days is locked, the rearrangement is consistent with the result of dynamic scheduling), the scheduling personnel manually appoints orders, equipment, moulds and time length or modifies the priority of the production scheduling orders, then the rearrangement is carried out, the appointed orders and the corresponding resources are regarded as occupied planning loads, recalculation is not carried out, and the rearrangement changes the scheduling result of unlocked orders. If not, the operation is performed again according to the scheduling principle (such as the order sequence rule and the resource load balancing principle).
S500) production scheduling is performed on the remaining orders scheduled in step S400 from the start time of the non-locking deadline, which is the time after the scheduling time in step S400, in the same manner as in step S400 and without locking the scheduling result. In this embodiment, the dynamic scheduling only starts on the fourth day (starting time of non-locking period) after the current time, and the order quantity is order quantity-order report quantity-planned quantity in the first three days, if the order quantity is 0, the order is not considered in the dynamic scheduling.
By the scheduling method, manufacturing enterprises can obtain the optimal production scheduling scheme which meets all assessment indexes and is subjected to simulation verification within limited time, and the decision risk is reduced, so that the working efficiency of planning and scheduling is improved, and the production control capacity and the response speed are improved.
