In the manufacturing enterprise of trades such as household electrical appliances, automobiles, the production line includes multiple types such as continuous punching press production line, laser cutting production line, tailors rolling production line usually, and all kinds of production lines arrange orderly production according to production plan overall, and the part of production line production has different kind and model specification, so the expansion outline size of every kind of part can have the difference, and the size of required former book (or called coil of strip) is different, and then causes the problem that traditional calculation mode work load is big, the error is big. The material control method can accurately, quickly and efficiently realize the material control of the production line, belongs to the typical application of intellectualization in supply chain links, and the scheme of the invention is specifically explained below.
Referring to fig. 1, fig. 1 provides a material management and control method for a production line according to an embodiment of the present invention, the method includes:
and 11, acquiring the theoretical steel consumption of the production line according to the production information of the production line.
Specifically, the production information may be obtained from a production plan of the production line, the production plan includes a historical planned yield, a historical actual yield, and a future planned yield, a historical period of the historical planned yield and the historical actual yield may be in units of days, weeks, and months, the future planned yield may be a production plan of approximately 2-3 months, of course, the future planned yield may be a production plan of approximately 6 months, and it is appropriate to select a production plan of approximately 2-3 months in order to avoid overstock of materials and operational pressure caused by cost occupied by inventory materials. Meanwhile, in order to ensure the accuracy of measurement and calculation, the yield value in the future month is as close as possible to the actual situation.
The production information includes information such as part number, part number name, specification, part production time, part production cycle, part thickness, part material, part width, and part number of each part, and the types of the parts are various. The production information is regularly updated or imported according to the production plan, and the accuracy of production information maintenance is ensured. For the production line of the cutting and rolling type, the steel coil is cut only along the width direction of the steel coil, and the cutting length is fixed, so that the theoretical steel consumption can be directly obtained according to the cutting quantity and the cutting length. Of course, for other types of production lines, the theoretical steel consumption needs to be calculated according to the consumption of the reel of a single part (or the consumption of a part).
In an alternative embodiment, the obtaining of the theoretical steel consumption of the production line according to the production information of the production line comprises:
determining the specification of the original coil according to the thickness of the part, the material of the part and the width of the part in the production information;
determining the number of the reels according to the number of the parts in the production information;
and obtaining the theoretical steel consumption according to the specification and the number of the original coils.
The specification of the raw coil is that a steel mill produces the raw coil with fixed specification according to production standard, the specification information corresponding to the specification of the raw coil comprises length, thickness, width, material, quality grade and the like, and when the device is used, the head of the raw coil is pulled to a production line for uncoiling. To meet the production quality requirements of parts, the thickness and the material of the parts must correspond to the width and the material of the specification of a raw roll, and the width of the parts must not be larger than the width of the specification of the raw roll; when the parts are produced, the unfolding outlines of the parts are usually repeatedly arranged along the length direction of the raw rolls, and the number of times of repeated arrangement can obtain the number of the parts to be produced, so that the theoretical steel consumption for producing the parts can be obtained according to the specification of the raw rolls and the number of the raw rolls.
In an alternative embodiment, determining the reel specifications from the part thickness, part material and part width in the production information comprises:
selecting the same part thickness and the same part material to obtain a width set;
obtaining a coil splicing scheme according to the width of the corresponding part in the width set;
and determining the specification of the original roll according to the splicing scheme.
The production information comprises different part thicknesses and different part materials of various parts, and the parts with different production standards are correspondingly produced. But the production execution standards of part of parts are the same, so that the parts can be produced by using reels with the same material and thickness, the part thickness and the part material are selected, and the flow of counting one by one is simplified. The obtained width set comprises all the part widths with the same part thickness and the same part material, and different splicing and rolling schemes can be obtained by combining the part widths in different modes. It will be appreciated that the number of width sets may be one or more, depending on the actual circumstances in which the production line is producing parts.
The width of the parts can be combined in a selected combination or a sequential combination. Wherein, the selection combination is selected according to the production time, manpower and equipment requirements of the production line, for example: corresponding production personnel are familiar with the parts in a production time period, and the part widths of the parts can be selected to be combined so as to ensure the production quality and efficiency of the parts; the corresponding production equipment is idle in a production time period, and the width of the parts can be selected to be combined so as to ensure the running coordination of the whole equipment of the production line. The splicing scheme obtained by selecting and combining has better flexibility and applicability, and is beneficial to the adaptability adjustment of the production line. The sequential combination is to arrange all the part widths in the width set and simultaneously arrange the original roll specifications, and the arrangement mode can be descending order or ascending order. Selecting the widths of the parts from large to small in sequence to be in the specifications of the correspondingly arranged reels, namely, the widths of the parts with large specifications are arranged in the reels with large specifications, updating the width states of the arranged parts and the positions, which are not arranged, of the reels with large specifications in the width direction, and selecting the widths of the parts, which are not arranged, from large to small in sequence until all the widths of the parts are completely arranged, so as to obtain a reel splicing scheme according to the whole arrangement result. Generally, the large-specification raw rolls are larger in quality, matched hoisting and processing equipment is larger, the small-specification raw rolls are opposite in correspondence, the width of the splicing scheme parts obtained by sequential combination is more reasonable in correspondence with the specification of the raw rolls, and production and allocation are facilitated. And correspondingly determining the specification of the original roll after the roll splicing scheme is obtained.
In an alternative embodiment, obtaining the rolling scheme according to the corresponding part width in the width set includes:
accumulating the widths of the parts in the width set to obtain a combined width; wherein the combined width is not greater than the specification width of the specification of the original coil;
obtaining a residual width according to the combined width and the specification width;
distributing the widths of other parts according to the residual width; wherein the widths of the other parts are the widths of the parts in the width set which are distributed to the parts except the combined width;
confirming that the part widths in the width set are fully allocated;
and according to the result of the complete distribution, obtaining a volume splicing scheme.
It should be noted that the width of the part may be a width value of the part, or a certain compensation amount may be set on the width value, and the compensation amount may be set correspondingly according to a multiple of the thickness of the part, so as to ensure that a lap exists between adjacent parts in the combined width, and the lap can compensate a positioning error of the production line, thereby ensuring that a qualified workpiece is produced; meanwhile, the strength and the rigidity of the strip material can be kept to a certain degree, and smooth feeding is guaranteed.
The residual width is the difference value between the specification width and the combined width, and before other part widths are distributed according to the residual width, whether the residual width is greater than a threshold value or not can be judged, wherein the threshold value is the minimum value of the part widths in the width set; if the residual width is not less than the threshold value, distributing the widths of other parts according to the residual width; if the remaining width is less than the threshold, indicating that the remaining width does not meet the requirements for allocating other part widths, then no other part widths are allocated. The part widths in the width set are fully allocated, indicating that the result of the full allocation includes all of the part widths in the width set, and the resulting lap scheme covers all of the part widths.
In an alternative embodiment, assigning other part widths based on the remaining width comprises:
arranging the rest width and the widths of other parts in a descending order;
and distributing the widths of other parts to the rest widths according to the descending order, and updating the rest widths.
And during distribution, distributing the maximum values of the descending order of the residual widths to the maximum values of the widths of other parts, and selecting a second large value (a second large value) for distribution if the maximum value of the residual widths is not larger than the maximum values of the widths of other parts in the distribution process. The remaining widths that have been allocated other part widths are updated to avoid duplicate allocations. Of course, for the residual width which is already allocated with other part widths, if the residual width still exists, the allocation can be continued until the residual width does not meet the allocation condition, so that the residual width is fully utilized, the loss of the original coil is reduced, the production cost of the part is reduced, and the allocation process can be solved by adopting a one-dimensional classical packing algorithm. The residual widths and the widths of other parts are correspondingly distributed according to the descending order, so that the calculated amount in the distribution process is effectively reduced, the distribution efficiency is improved, and the distribution result is more reasonable.
In an alternative embodiment, confirming that the part widths in the width set are fully allocated comprises:
judging whether the widths of other parts are completely distributed to the rest width;
if yes, confirming that the part width in the width set is completely distributed;
if not, the widths of other parts are distributed to the specification widths except the combined width.
If the width of other parts is not completely distributed to the rest width, the width of other parts is distributed to the specification width beyond the combined width so as to ensure that the width of the parts can be distributed for production. Of course, the distribution result of the unallocated part widths may be output, and the width set may be reconstructed based on the distribution result to perform distribution.
In an alternative embodiment, determining the number of reels from the number of parts in the production information comprises:
acquiring the capacity planning requirement, the in-production order and the inventory of the production line;
the quantity of the reels is obtained according to the demand of the capacity plan, the order of the production, the stock and the quantity of the parts.
Specifically, the capacity planning requirement is the planned production capacity of the part, the production order is the production capacity of the part which is distributed to the production line, and the stock is the part which is finished to be produced; therefore, the part quantity is the difference between the demand of the capacity plan and the in-production order and the stock so as to accurately obtain the quantity of the parts to be produced and further accurately obtain the quantity of the reels. After the exact theoretical amount of steel has been obtained from the reel specifications and the number of reels, step 12 is entered.
And step 12, generating the material breaking node information and the order requirement information of the production line according to the consumption, the stock and the theoretical steel consumption of the production line.
Wherein, the consumption can be calculated according to the usage in a period of time, for example: and calculating the daily average consumption of a certain month, calculating the daily average yield of the production line in the month, dividing the monthly yield by the number of days in the month to obtain the daily average yield, multiplying the daily average yield by the unit consumption of the parts to obtain the daily average consumption, and the unit consumption of the parts is the amount of the raw rolls required by the production of a single part.
The stock quantity is the stock quantity of the raw rolls, and the difference value between the stock quantity and the theoretical steel consumption is the required quantity of the raw rolls needed to be used in the production planning period of the production line. Through the comparison consumption and the stock roll demand, the material breaking node time of the current production line is convenient to know, the corresponding material breaking node information and the ordering demand information can be generated, and a user carries out stock according to the information so as to prevent the material breaking from generating adverse effects on the production line.
In an optional embodiment, the generating of the material breakage node information and the ordering requirement information of the production line according to the consumption, the stock quantity and the theoretical steel consumption of the production line comprises the following steps:
acquiring the inventory of the production line; wherein, the inventory comprises the warehousing quantity and the non-warehousing quantity in transit;
generating material breaking node information according to the consumption, the in-stock quantity and the theoretical steel consumption;
and generating order demand information according to the inventory quantity, the in-transit quantity and the theoretical steel consumption.
In the actual supply of steel coils, due to the limitation of transportation and production conditions and other reasons, a steel plant cannot transport all the original coils required by orders to a warehouse for storage at one time, and the transported and stored coils are in-warehouse quantity in the continuous supply process and can be directly provided to a production line for production; the method is characterized in that the original rolls which are not transported and put in storage for orders are in-transit quantities, the in-transit quantities are generally transported to a warehouse for storage before material breaking of a production line, but statistics needs to be carried out on the in-transit quantities to prevent accidents that the in-transit quantities cannot be transported to the warehouse as required, and the statistics of the in-transit quantities has great significance for early warning of material breaking.
The difference between the stock quantity and the theoretical steel consumption is the required quantity of the original coil needed to be used in the production planning period of the production line. And obtaining the information of the material breaking nodes by comparing the consumption with the required quantity of the original coil.
The in-transit amount is the original roll which has been ordered but not delivered to the warehouse. The prediction of the stock quantity is to predict the quantity required by the production cycle of the production line according to the quantity in transit, the quantity in stock, the theoretical steel consumption and the like, calculate the quantity of steel required by parts of various types, provide guidance for ordering and replenishing goods and avoid repeated ordering. The ordering demand information is divided into an intelligent prediction A and an intelligent prediction B. The prediction result of the intelligent prediction scheme A only comprises a going purchase contract, and provides reference for purchasing; the prediction result of the intelligent prediction B scheme comprises a going purchase contract and a stock purchase contract, and can guide acquisition to carry out centralized batch ordering.
In an optional embodiment, the material failure node information includes part information, a material failure early warning level and an early warning reason.
The part information comprises part numbers and specifications, and each part has a unique number according to the specifications; the material failure early warning level comprises dangerous stock and warning stock; wherein, dangerous stock and warning stock can be set according to the time of expecting absolutely, for example: setting the stock as dangerous stock in 20 days before the material is cut off and setting the stock as warning stock in 10 days before the material is cut off; the early warning reasons comprise production line output reasons and steel mill supply reasons, the material breaking reasons can be known in all directions through the early warning reasons, and purchasing staff can conveniently and timely adopt a corresponding method to process.
