Forging: is one of four processes of engine production, and is positioned at the forefront end of an engine production chain. The product comprises an engine crankshaft, a connecting rod and a gearbox belt pulley.
Scheduling production plans: scheduling (scheduling) is a method for setting time for future work to be completed, i.e. an execution mode for resource allocation, which allocates the results of capacity planning and overall production planning (including equipment, manpower and space, etc.) to each work, activity or customer, and reconciles three mutually conflicting objectives of efficiency, inventory level and service level, so as to obtain a proper balance point.
In factory forging shop production activities, the process is highly automated, but informationized basis is poor, and manual accounting is mainly managed on site. In the related art, the on-site listing and the standing book recording are mainly carried out in a manual copying equipment recording mode, and complex writing is difficult to store. In addition, the logistics and the production process are both paper records, and the management and the statistical analysis of the production are inconvenient. Meanwhile, the production plan is manually made into a forging and pressing plan and a heat treatment plan according to experience by a team through a stock plan processed by a receiver, the efficiency is low and errors are easy to occur, the corresponding generation plan is stored in a user computer to form a single information island, and certain hysteresis exists in plan change. Therefore, the above technical problems need to be solved.
Based on this, an embodiment of the present invention provides a method, a system and a storage medium for scheduling production of parts in a workshop, which can realize accurate scheduling of production of parts in a workshop and effectively improve efficiency of scheduling production. Referring to fig. 1, the method of the embodiment of the present invention includes, but is not limited to, step S110, step S120, step S130, step S140, step S150, and step S160.
Specifically, the method application process of the embodiment of the invention includes, but is not limited to, the following steps:
s110: setting preset schedule data. The preset schedule data comprises a preset demand plan.
S120: when the current scheduling data is determined to meet the preset scheduling conditions, the preset scheduling part is selected according to the preset demand plan, and the target scheduling part is obtained.
S130: and when the preset scheduling verification is determined to pass according to the target scheduling part, calculating the number of the scheduling parts by the preset scheduling influence factor.
S140: and calculating the storage quantity of the material box according to the product discharge quantity.
S150: and when the bin quantity in the bin is determined to meet the preset residual bin data, performing post-treatment advanced time verification processing according to the preset post-treatment advanced time and the preset shipment demand.
S160: and when the post-treatment advanced time verification treatment is confirmed to pass, carrying out part production scheduling according to the part production scheduling quantity, and updating the current production scheduling data to obtain a target production scheduling.
In the working process of the embodiment, the embodiment of the invention firstly sets preset scheduling data. Specifically, the embodiment of the invention needs to set and maintain corresponding calculation data, namely preset schedule data, in advance before the production schedule of workshop parts is carried out. By way of example, the embodiment of the invention obtains the corresponding preset demand plan through the corresponding part demand plan management page. For example, the embodiment of the invention sets the corresponding preset demand plan through a preset interface or a manual input mode, wherein the interface mode is to manually guide the plan made offline into the system based on the machining and casting production plan, and then issue the plan to the forging shop scheduling system through the interface to serve as the demand plan, namely the preset demand plan. It is easy to understand that in the embodiment of the invention, the corresponding preset demand plan is set by means of the post-processing demand plan which is accessed from the processing and casting system interface or manually imported, so that the original demand in the demand plan can be obtained. Then, when the current scheduling data is determined to meet the preset scheduling conditions, the embodiment of the invention performs the selection of the preset scheduling parts according to the preset demand plan to obtain the target scheduling parts. Specifically, the embodiment of the invention analyzes the current scheduling plan to judge whether the current scheduling plan data meets the preset scheduling conditions. In the embodiment of the present invention, the current scheduling data refers to a current scheduling schedule, such as a current month scheduling schedule or current scheduling date and shift scheduling data. According to the embodiment of the invention, whether the remaining capacity exists or whether each production schedule is finished is determined by analyzing the current production scheduling data, so that whether the production scheduling is needed is determined, and when the current production scheduling data is determined to meet the preset production scheduling conditions, the preset production scheduling part is selected through the preset demand schedule, and the part needing to be scheduled is obtained, namely the target production scheduling part is obtained.
Further, when it is determined that the preset scheduling verification is passed according to the target scheduling component, the embodiment of the invention calculates the component scheduling number by the preset scheduling influence factor. Specifically, after the selection of the production scheduling parts is completed, the embodiment of the invention performs corresponding preset scheduling verification on the obtained target production scheduling parts, such as verification of the state of a die, shipment condition and the like. When the preset scheduling verification passes, the embodiment of the invention calculates the scheduling quantity through the preset scheduling influence factor to obtain the corresponding part scheduling quantity. Then, the embodiment of the invention calculates the stock quantity of the material box according to the product discharge quantity. Specifically, the bin in the embodiment of the invention is a packaging container of goods, so that the goods can be conveniently stored and transported, and the quantity of the bin in the warehouse refers to the quantity of the bin stored in the warehouse, so that the storage condition of the goods can be reflected. According to the embodiment of the invention, the bin inventory is calculated through the calculated part production quantity, so that the sufficient supply of raw materials and parts on a production line is ensured, the bin inventory is updated in time, and the accuracy and the production efficiency of a production plan are effectively improved. Correspondingly, when the bin in-stock quantity is determined to meet the preset residual bin data, the embodiment of the invention performs post-treatment advanced time verification processing according to the preset post-treatment advanced time and the preset shipment demand quantity. Specifically, in order to alleviate the problems of delayed production progress or resource waste and the like caused by unreasonable lead time of the post-processing task, the embodiment of the invention firstly judges whether the stock quantity of the material box meets preset material box data, and when the stock quantity of the material box is confirmed to meet the preset residual material box data, the embodiment of the invention performs post-processing lead time verification through preset post-processing lead time and preset shipment demand quantity so as to ensure that the post-processing task can be completed within a specified time range and avoid adverse effects on production scheduling. The preset post-treatment advance time corresponding to different products in the embodiment of the invention is different, and the preset shipment demand is also different. Finally, when the post-processing advanced time verification processing is determined to pass, the embodiment of the invention performs the product scheduling according to the product scheduling quantity, and updates the current scheduling plan data to obtain the target scheduling plan. Specifically, after the post-treatment early time verification treatment is passed, the corresponding parts are scheduled according to the part scheduling quantity, and meanwhile, the current scheduling plan data is updated, such as part scheduling update, part in-stock quantity update, part month mould usage amount update, residual capacity update, bin in-stock quantity update and the like, so that a target scheduling plan is obtained, accurate and reliable workshop part production scheduling is realized, and the production plan is not required to be manually scheduled and repeatedly adjusted and modified, thereby effectively improving the efficiency of the production scheduling.
In some embodiments of the present invention, the preset schedule data is set, including but not limited to the following steps:
setting a preset demand plan, a part mold type, a part mold service life, an initial stock quantity of the part, a preset shift capacity number and an initial stock quantity of the material box.
In this embodiment, the preset schedule data in the embodiment of the present invention further includes a part mold type, a part mold life, an initial stock quantity of the part, a preset shift capacity number, and an initial stock quantity of the bin. Specifically, the embodiment of the invention needs to maintain the preset scheduling data in advance before scheduling, and maintains the corresponding preset scheduling data through the corresponding data maintenance page. Exemplary, the embodiment of the invention sets the type of the part mold and the service life of the part mold corresponding to the part through the part information maintenance page. Correspondingly, the embodiment of the invention calculates the front total required amount of the month of each part according to the corresponding preset requirement plan (front required amount) through the set service life of the part mould, for example, the front total required amount of the month of each part is divided by the corresponding service life of the part mould and is rounded upwards, so that the total required mould set number of each part is calculated according to the month. In addition, the embodiment of the invention sets the initial inventory quantity of the parts corresponding to the parts through the part information maintenance page, wherein the initial inventory quantity comprises the initial inventory quantity before heating and the initial inventory quantity after heating, so that the current day plan residual inventory quantity of each part is calculated according to the date. In the embodiment of the invention, the daily planned remaining amount of the warehouse is obtained by subtracting the daily original demand amount from the daily remaining amount of the warehouse before the daily planned remaining amount of the warehouse is communicated and adding the daily output. Meanwhile, the embodiment of the invention sets the number of shift productions of the part level and the non-part level through the factory production information management page, namely the preset number of shift productions. In this embodiment of the present invention, a plurality of shifts may be set daily, so the shifts of the embodiment of the present invention are represented by a combination of dates and shifts, for example, "date+shift", and after each time of discharging, the remaining available capacity of the corresponding date shift is calculated, and the first time of discharging (including starting the shift again after the middle interval) the product capacity of the corresponding date shift is automatically halved. The remaining capacity of each shift in the embodiment of the invention is obtained by the scheduling quantity of the corresponding shift according to the initial capacity of the corresponding shift. Further, the embodiment of the invention sets the initial stock quantity of the hoppers of different hoppers through the container management page, so that the daily residual stock quantity after each discharge is calculated through the initial stock quantity of the hoppers, for example, the daily residual stock quantity is obtained by adding the stock quantity of the hoppers which are left in the previous day and the stock quantity of the hoppers which are planned to be returned in the current day and subtracting the stock quantity of the hoppers which are planned to be occupied in the current day. The bin volume of the bin planned to be returned on the same day in the embodiment of the invention is obtained by dividing the original daily demand by the standard bin packing number SNP (Standard Number of Packing) and rounding up, and the bin volume of the bin planned to be occupied on the same day is obtained by dividing the daily discharge volume by the standard bin packing number and rounding up. It is easy to understand that in the embodiment of the invention, the logistics and production processes are electronically managed, so that the management of feeding, warehouse-out, warehouse-in, checking, flowing card printing and the like is realized, the data on the equipment are automatically collected, the manual record is reduced, and the automatic statistics and analysis of the production data are realized.
In some embodiments of the present invention, when it is determined that the current scheduling data meets the preset scheduling conditions, a preset scheduling component is selected according to a preset demand schedule, so as to obtain a target scheduling component, including but not limited to the following steps:
and judging whether the scheduling of the shift with the preset date is finished according to the current scheduling plan data. Wherein the preset date includes a last day of the preset scheduling period.
And when the fact that the scheduling is not completed on the preset date is determined, judging whether the residual capacity exists in the current scheduling shift according to the current scheduling plan data.
And when the current scheduling shift is determined to have the preset residual capacity, selecting and obtaining the first scheduling part according to the preset demand plan. Wherein the first product comprises a product which is required on the same day.
And screening the first product according to the corresponding daily remaining warehouse quantity and daily front demand quantity of the first product to obtain a second product.
And screening the second product to obtain the target product according to the consumption completion time of the second product.
In this embodiment, the embodiment of the present invention first determines whether the schedule of the preset date is completed according to the current schedule data. Specifically, referring to fig. 2, in the embodiment of the present invention, the preset date includes the last day of the preset scheduling period, and the embodiment of the present invention determines whether to continue scheduling by determining whether the scheduling shift is completed on the last day of the preset scheduling period. For example, when the month is taken as a preset scheduling period, the embodiment of the invention determines whether the scheduling of the current month has been completed by judging whether the shift of the last day of the scheduling of the current month has been completed. Then, when it is determined that the scheduled production is not completed on the preset date, the embodiment of the invention judges whether the residual capacity exists in the current production schedule according to the current production schedule data so as to determine whether the current capacity condition can meet the production demand. Correspondingly, when the preset capacity exists in the current scheduling shift, the first scheduling part is selected according to the preset demand plan. Specifically, when the embodiment of the invention determines that the preset surplus capacity exists on the current production date and shift, the embodiment of the invention selects the production products through the preset demand plan. Accordingly, in the embodiment of the invention, firstly, the parts which are not required in the current day are filtered through the preset requirement design, and the first production part, namely the parts which are required in the current day, is selected. Then, according to the corresponding daily remaining warehouse quantity and daily front-end demand quantity of the first product, the embodiment of the invention screens out the first product to obtain a second product. It is easy to understand that the embodiment of the invention screens out the parts with the residual quantity in the current day being smaller than the pre-required quantity in the current day from the first-row products, so as to obtain the corresponding second-row products. Finally, according to the embodiment of the invention, the target product is obtained by screening the second product according to the consumption completion time of the second product. Specifically, according to the embodiment of the invention, the part with the shortest time for consuming the completion is selected from the second product to be produced as the target product to be produced according to the time for consuming the completion.
It should be noted that, in some embodiments of the present invention, the embodiments of the present invention select the parts remaining in the warehouse on the same day less than the minimum remaining warehouse quantity of the parts to perform the warehouse repairing, so as to maintain the related data of the parts. In addition, when there is surplus capacity, the embodiment of the present invention acquires, as a target production-output product, a product that needs to be produced in advance every other day. Further, in the case that there is surplus capacity, the embodiment of the present invention selects the parts that are required on the day and the next day, and selects the corresponding parts as the target production-scheduling parts according to the urgency of the stock consumption. Further, in the case that there is surplus capacity, the embodiment of the present invention selects the parts that are required every other day, and selects the corresponding parts as the target production parts according to the urgency of the stock consumption. Finally, in the case that there is surplus capacity, the embodiment of the present invention selects the parts that are currently in production, and selects the corresponding parts as the target production parts according to the urgency of the stock consumption.
In some embodiments of the present invention, when it is determined that the bin inventory satisfies the preset remaining bin data, a post-processing lead time verification process is performed according to the preset post-processing lead time and the preset shipment demand, including, but not limited to, the following steps:
And when the shift is determined to be the first shift scheduling shift according to the scheduling shift data, and the first remaining inventory quantity is smaller than the first remaining bin data, performing post-processing advanced time verification processing through the preset post-processing advanced time and the preset shipment demand quantity. Wherein the first remaining inventory includes a remaining bin amount after the first shift is performed by the first shift.
Or when the shift is determined to be the non-first shift scheduling shift according to the scheduling shift data, and the second remaining stock quantity is smaller than the second remaining bin data, performing post-processing advanced time verification processing through the preset post-processing advanced time and the preset shipment demand quantity. Wherein the second remaining inventory includes a remaining bin amount after the shift is discharged by the non-first shift schedule.
In this embodiment, referring to fig. 3, the embodiment of the present invention first determines whether the current scheduling shift is the first scheduling shift according to the corresponding scheduling shift data. When the current scheduling shift is determined to be the first shift scheduling shift according to the scheduling shift data, the embodiment of the invention judges whether the first remaining inventory is larger than first remaining bin data. Wherein the first remaining inventory amount includes a remaining bin amount after being discharged by a first shift of production. For example, the embodiment of the invention judges whether the number of the bins remained after the first shift is discharged, namely, the first remaining warehouse quantity is smaller than 80. When the number of the remaining bins after the first shift production shift is determined to be smaller than the first remaining bin data, such as smaller than 80, the embodiment of the invention performs post-processing advance time verification processing by presetting post-processing advance time and presetting shipment demand. Correspondingly, when the current scheduling shift is determined to be the non-first scheduling shift according to the scheduling shift data, the embodiment of the invention firstly judges whether the second remaining inventory quantity is smaller than the second remaining bin data. Specifically, the second remaining inventory level in the embodiment of the invention includes a remaining bin level after the production shift is performed by the non-first shift schedule. For example, the embodiment of the invention first analyzes whether the remaining bin quantity after non-first shift production shift discharge, i.e. the second remaining inventory quantity, is smaller than the second remaining bin data, e.g. smaller than 20. When the second remaining warehouse quantity after the non-first shift scheduling and shift scheduling is determined to be smaller than 20, the embodiment of the invention eliminates the post-processing early time verification processing by presetting the post-processing early time and restricting shipment, thereby realizing more accurate post-processing early time verification and effectively improving the rationality and reliability of the workshop part production scheduling.
In some embodiments of the present invention, the post-process lead time verification process is performed by presetting the post-process lead time and presetting the shipment demand, including, but not limited to, the steps of:
and calculating to obtain the first time consumption according to the preset shipment demand and the current day remaining in the warehouse.
And calculating a second time consumption according to the preset shipment demand, the preset front demand and the remaining warehouse in the same day.
And performing post-treatment advance time verification according to the first consumption time, the second consumption time and the preset post-treatment advance time.
In this embodiment, the embodiment of the present invention first calculates the first time period for consumption according to the preset shipment demand and the remaining inventory of the day. Specifically, referring to fig. 3, the first time period of consumption in the embodiment of the present invention refers to the estimated time period of completion of the consumption of the parts remaining in the warehouse on the next day. The preset shipment demand in the embodiment of the present invention refers to the shipment demand per hour in the future. For example, in the embodiment of the present invention, the preset shipment demand for the connecting rod product and the pulley product is 400 per hour, and the preset shipment demand for the crankshaft product is 300 per hour. The embodiment of the invention is obtained by presetting the shipment demand and calculating the expected consumption completion time of the parts remaining in the warehouse on the day next to the day, namely the first consumption time, by dividing the current-day-remaining-warehouse-leaving quantity by the preset shipment demand and rounding up. Then, the embodiment of the invention calculates a second time consumption according to the preset shipment demand, the preset front demand and the current day remaining in the warehouse. Specifically, the second time-consuming period in the embodiment of the present invention refers to a time-consuming period in the next day when the demand that the part fails to meet on the same day. Accordingly, in the embodiment of the present invention, the time consumption of the demand that the part fails to meet on the current day on the next day, that is, the second time consumption, is obtained by dividing the difference of the current day front demand (preset front demand) minus the current day remaining in the warehouse by the corresponding shipment demand per hour, that is, the preset shipment demand. Finally, the embodiment of the invention performs the post-processing advanced verification through the first consumed time length, the second consumed time length and the preset post-processing advanced time. Specifically, the embodiment of the invention performs post-processing advance time verification by analyzing whether the sum of the first consumed time length and the second consumed time length is smaller than or equal to the preset post-processing advance time. Correspondingly, when the sum of the first consumption time and the second consumption time is smaller than or equal to the preset post-treatment advance time, the embodiment of the invention does not carry out corresponding part production. Otherwise, when the sum of the first consumed time length and the second consumed time length is greater than the preset post-processing advance time, the embodiment of the invention executes the corresponding product scheduling operation.
In some embodiments of the present invention, when determining that the preset schedule check is passed according to the target schedule, calculating the number of schedule of the parts by the preset schedule influencing factor includes, but is not limited to, the steps of:
and when the target production part is the first product part, judging whether the die set number in the current month reaches the preset target number. And when the number of the die sets in the current month is determined to not reach the preset target number, and the target production scheduling part has shipment requirements in the current day, calculating to obtain the part production scheduling number through the service life of the part die and the residual capacity of the preset shift. Wherein the first product part comprises a link product part.
Or when the target product is the second product, judging whether the die set number in the current month reaches the preset target number. And when the number of the die sets in the current month is determined to not reach the preset target number and the current product date shift is the preset shift-on time, carrying out preset processing condition analysis. And when the preset processing conditions are determined to meet the first processing conditions, calculating to obtain the product production quantity through the service life of the product mold and the residual capacity of the preset shift. The second product part comprises a crankshaft product part or a belt wheel product part, the first processing condition comprises that the next-day shipment demand of the target product is not zero, the current residual warehouse quantity is equal to the minimum residual warehouse quantity, and the residual mantissa of the die of the target product is not zero.
In this embodiment, the target product of the embodiment of the present invention is divided into a first product part and a second product part, that is, a part corresponding to the first product and a part corresponding to the second product. Specifically, referring to fig. 2, the first product in an embodiment of the present invention comprises a link product. Accordingly, the first product part in the embodiments of the present invention includes a link product part. When the target product is determined to be the first product, that is, the connecting rod product, the embodiment of the invention first judges whether the number of die sets in the month reaches the preset target number, for example, whether the corresponding number of die sets in the month of the first product is full, that is, whether the number of die sets required for producing the first product in the month has reached the target number. Further, when it is determined that the number of die sets in the current month does not reach the preset target number, that is, the number of die sets in the current month corresponding to the first product is not full, the embodiment of the present invention then analyzes whether the shipment requirement exists in the current day of the target product discharge. Correspondingly, when the number of the die sets in the current month of the first product part is determined to not reach the preset target number, and the target product scheduling part has a shipment demand in the current day, the embodiment of the invention calculates the product scheduling number through the service life of the part die and the residual capacity of the preset shift. For example, when the number of remaining sets of the current part mold is an integer, the embodiment of the present invention first determines the relationship between the current shift remaining capacity (preset shift remaining capacity) and the part mold life. When the remaining capacity of the current shift on the same day is greater than or equal to the service life of the part mold, the number of the part shifts, namely the number of the part shifts, in the embodiment of the invention is equal to the service life of the part mold. Otherwise, if the remaining capacity of the current shift is smaller than the service life of the part mold, the number of the part shifts in the embodiment of the invention is equal to the remaining capacity of the current shift. In addition, when the remainder exists in the number of the remaining sets of the current part molds, the embodiment of the invention determines the number of the product shifts by the relation between the remaining capacity of the current shift on the same day and the remaining life of the single part molds. When the work-shift residual capacity of the part is larger than or equal to the single-die residual life of the part, the work-shift production quantity of the part in the embodiment of the invention is equal to the single-die residual life of the part. On the contrary, when the remaining capacity of the part in shift is smaller than the remaining life of the single mold of the part, the embodiment of the invention takes the remaining capacity of the part in shift in the same day as the number of the part in shift.
Further, when the target product is the second product, the embodiment of the invention first determines whether the number of die sets in the current month reaches the preset target number. Specifically, in the embodiment of the present invention, the second product part includes a crankshaft product part and a belt wheel product part, when the target product is a crankshaft product part or a belt wheel product part, and the number of die sets in the month does not reach the preset target number, that is, the number of die sets in the month of the target product part is not full. When the current product date and shift is determined to be the shift-on time, namely, the preset shift-on time, the embodiment of the invention performs preset processing condition analysis to determine whether the first processing condition is met. The first processing condition in the embodiment of the present invention includes that the next-day shipment demand of the target product is not zero, that is, the target product has shipment demand on the same day, and the current remaining inventory quantity is equal to the minimum remaining inventory quantity, that is, the current remaining inventory quantity and the minimum remaining inventory quantity of the product, and the remaining die mantissa of the target product is not zero, that is, the target product has remaining die mantissa. Further, when the preset processing condition is determined to meet the first processing condition, the embodiment of the invention calculates the product production quantity through the service life of the product mold and the residual capacity of the preset shift to obtain the product production quantity.
