Embodiment
Billboard is formed: electronic board is by come back and detailed (also i.e. project) form, and billboard new line is in units of order, comprises the demand number of gathering, process route, sequence, record type, work centre, production order number, production order status etc.; Because billboard is using operation as minimum dispensing unit, so detail is in units of operation, comprises the demand number of gathering, process route, platform position, demand material, factory, stock locations, recoil mark, will the specifying informations such as time be expected.Meet the requirement of lean production dispensing, in lean logistics banner system, by the demand number of gathering, the new line of billboard is connected with detail.
Work centre in the present invention comprises production subsidiary factory and logistics center.
One, billboard generates:
1, the production schedule of motor-car manufacture is mainly derived from produces order and maintenance order (being also maintenance work order), the complicacy manufacturing the production schedule in view of motor-car and the change that may exist, and inevitably impact is changed in engineering design, logistics center is to production subsidiary factory issuance of materials, do not take the active means of distribution arranged based on the stable production schedule, but take means of distribution as required, production subsidiary factory is needed to propose to expect demand based on the production schedule in three days, subsequent production subsidiary factory submits to demand personnel according to expecting demand inventory, with operation and/or teams and groups' node, will expect that the release of demand inventory is submitted to logistics center, and the transmission of these production orderings has all been come by billboard, here the production schedule deriving from maintenance work order directly generates billboard data, and the billboard deriving from maintenance order only has data.
Based in the lean logistics system of billboard, if there is multiple billboard, can writes in the table of backstage, be focused on by background job.
2, billboard generates, and backstage can be divided into automatically to run formulate manual with foreground
2.1 high for priority level, to need emergency treatment billboard, can adopt the manual input mode in foreground to submit billboard to.When formulating by hand on foreground, system can judge the quantity that user inputs, if the billboard quantity that will run of user's input can point out mistake more than 100 systems, this act as avoids people to be input error, improves the operational efficiency of system.
2.2 motor-cars in process of production, each is produced order and relates to material process up to ten thousand, large material is so doted on for quantity, system adopts the mechanism of parallel processing, method for splitting is defined on backstage, system determines according to operation the quantity generating billboard, such as: there are 23 operations on backstage, there are 10 work orders, each work order has 20 operations, operation can be calculated by system, i.e. how many billboard quantity, calculate according to the operation in work order, as each operation has 100 kinds of materials, namely each work order has 2000 billboard, by all order operation data, namely need the data calculating billboard quantity to carry out cycle labeling and become A, B, C, 23 name (wherein A such as D, B, C, D etc. are job name), during first job run, label taking note is the data of A, during second job run, label taking note is the data run of B, by that analogy, because every procedure will new and old calculating repeatedly, in ERP, it is fewer that table stores data, efficiency is higher, so adopt this mechanism, substantially increase the operational efficiency of billboard, substantially a large amount of data runs within tens minutes, can be made complete, the quantity that certain operation splits arranges according to the portfolio of reality, when the changing greatly of portfolio, can again adjust.Here, single central processing unit computing machine that can perform many instructions simultaneously or process multiple data item simultaneously can be adopted also can to adopt multiple processor system.
Simultaneously, need when mark to calculate weight, this weight is distinguished, as shown in Figure 3, because general assembly material accounts for about 60% of total ratio according to production subsidiary factory, so system is when background process, the operation of 60% can be distributed to general assembly, bogie is set to 15%, and car body design is 25%, server resource can be utilized to greatest extent like this, calculate the quantity of billboard with the fastest speed.Certainly the distribution of this accounting can adjust according to the business datum of reality, and such as, when marking during job name, if the data of the operation bogie subsidiary factory of A exceed 25% of total amount, system automatically can move on to next job name to the operation of bogie and remove mark.Like this, effectively data are assigned in 23 background jobs, and reasonably control the operation quantity of each operation subsidiary factory.It is rational for guaranteeing that the billboard data run out are distributed.
2.3 when operation generates billboard detail, because data volume is larger, the data of billboard are inserted and calculated is all that background job performs calculating, like this, the mistiming is there is with practical business, also mean and there is variance data, system has added a computing mark in the table of billboard detail to be generated, when running generation billboard and being detailed, system can first by this get, will generate the data of billboard computing mark be set to " X ", after system operations complete generation billboard detail, then computing mark is put sky again.Adopt this mechanism, the data effectively avoiding billboard are repeated to capture and are calculated, and the phenomenon generating billboard Data duplication occurs.Simultaneously, system is in order to improve the travelling speed of billboard, gibberish is avoided to run, during each run, data for production work order are read in again, and be also repeatedly again read in when reading operation data, guarantee that the data of each to get, calculating are all up-to-date, the most real-time data, ensure that the accuracy that billboard data calculate.
3, demand billboard to be expected
Demand inventory will be expected will expect that billboard form is submitted to according to operation and/or teams and groups' node in lean logistics system by production subsidiary factory, is discharged into logistics center.There is the following two kinds form:
1) discrete piece will expect demand inventory: user cannot revise quantity required, and the background job of discrete piece divides into groups to calculate by operation;
2) recoil material to expect demand inventory: user can revise quantity required, simultaneity factor also can analog computation suggestion quantity required.Here recoil material refers to the inconsistent material of the unit of materials and forwarding unit, such as paint and so on, the unit of issuance of materials is tank/bucket, but the unit produced when consuming is gram, the actual consumption quantity of usual this material was difficult to statistics before production completes, and therefore recoil material manages in the subsidiary factory storehouse of production subsidiary factory.Logistics billboard operationally, carry out gathering issuance of materials by the feature according to recoil material.
Two, the production schedule changes
Unavoidably there is the possibility of change in production order, three daily plannings, therefore can cause expecting that demand billboard produces to change, system can according to original material data, see if there is outbound record, original outbound number and demand number are compared simultaneously, if without outbound, carry out outbound by the quantity that needs of new material; If there is outbound record, namely cancelling stocks is carried out to raw material, new materiel warehouse-out, produce one and move back a neck.
Changing the time point occurred may be will before or after material demand in submission.After expecting that demand is submitted, also may be picked and join or made outbound list.
Processing mode is as follows:
The first situation: if concerned process steps node to expect that demand inventory is not submitted or submit to but do not picked join, then be automatically appended to and formerly will expect demand odd numbers (reserved number+record type+operation ID+ submits demand sequence number to);
The second situation: if concerned process steps node to expect that demand inventory is submitted and pick join (pick containing part and join), what then automatic generation was new will expect in demand odd numbers (reserved number+record type+operation ID+ submits demand sequence number+serial number to), now, submission will expect demand sequence number, + 1 to be expected on demand sequence number basis former, will expect that demand sequence number initial value is 1 here.
Three, to the material returned process will expected in demand billboard
Because produce the change of order, can produce material returned request, also developed because of practical business demand in system, logistics department initiatively carries out the function of the material returned and neck material to the material sent out; A neck function is moved back in system support one, namely the material returned of certain material is applied for, the neck material of the material of tackling mutually can be applied for simultaneously, also support the material returned of single material, production subsidiary factory needs propose report material returned request according to the Production requirement of reality and variation, and logistics tally-man confirms the material returned according to the issuance of materials situation of reality, as one moves back a neck, while the material returned, allot new material, guarantee production subsidiary factory, logistics delivery, receive unanimously.
Expect that the material returned in demand billboard has three kinds of states: the non-outbound of demand be expected, requirement section outbound be expected, the complete outbound of demand will be expected, contingent various material returned demand in practical business is calculated accurately, as following table in systems in which by different fields, different values:
Note: lean logistics system is by 6 fields of upper table, and three states process all material returned requests likely occurred, such as,
ZDSTS_ASS=0 is represented: the non-outbound of demand be expected;
ZDSTS_ISS=1 is represented: have material returned request, material returned request key value with to expect that demand is inconsistent.
Do not have this state for " (the nothing) " system in upper table, system also can not carry out the such setting of ZDSTS_ISS=2 or ZDSTS_CIS=2.
Four, mistake billboard adjustment function
When producing order, the preservation of maintenance order, the generation will expecting demand schedule can be triggered, but in the practical business that motor-car is produced, can because design alteration causes the change of producing operation teams and groups, material, platform position in order, so according to reality, the data of billboard will will expect that need state carries out changing or locking, billboard data can not be generated after locking, but generation daily record data, be recorded in log sheet, here, the type of daily record comprises: the change of production work order, three daily planning changes and MRP change etc.
System, when designing, take into account all situations of producing order variation, concrete detailed as follows:
Note:
1) order status is that " X " represents locked, and locked data can not generate billboard data, but are stored in log sheet, the process of products for further;
2) for order demand change type be: the state of " increase material " be " (single) ", expression only have a kind of state, system according to expecting that need state directly processes;
3) have two kinds in the state of " change of operation teams and groups ": " mode one " and " mode two ", system according to circumstances performs respectively,
Such as: for expecting that need state is: " do not submit to/or submitted to but cancelled ", " submitted to and do not cancelled ", the treating method of system is: directly change;
For expecting that state is " all or part of transfer items ": for what transferred items, system selection approach one, locks this operation, does not generate billboard data, but generate daily record data (subsequent treatment: first submit the material returned request application material returned to by Ling Liao department, then rechange); For what do not transfer items, system selection approach two, directly changes.
The wrong material billboard data that the artificial maintenance mistake identified, the locking of production order, material locking, Material Cost do not have the reasons such as maintenance, design alteration to cause are saved in log sheet by system meeting automatically, next time is when running, system can perform the generation of billboard automatically again to the data of mistake, until the data genaration billboard of this mistake, just can delete this record in error log record sheet, therefore need regularly to start wrong billboard adjustment function, information flow according to up-to-date production order adjusts wrong billboard, ensure that the promptness that billboard adjusts.
But, be not all misdata generating daily record, finally all can generate billboard data, such as: change recoil setting, change material type, change MRP group, these may cause data run mistake, strictly forbid in systems in which, when there is the log information of this kind of mistake, need artificially to check.In addition, expect the project that demand is closed, also can not produce material billboard again, these need manual deletion.

Due to, monthly can produce up to ten thousand and produce order, namely the issuance of materials of hundreds of thousands procedure even up to a million is had, these materials are allowed to be dealt into corresponding production team in suitable time, place, guarantee the demand that lean is produced, billboard logistics platform devises tally-man, goods yard, material function one to one; Namely after guaranteeing that billboard runs, each material, all can corresponding corresponding goods yard, unique tally-man, guarantee that responsibility is clear and definite, can review, when tally-man can see oneself needs, feeding place, send to operation, accomplish to provide and deliver as required; Make the granularity refinement of logistics management.System sets up the contrast relationship in material, tally-man, goods yard, guarantee each material have tally-man be responsible for, the corresponding shipment goods yard of each material.What tally-man every day can run logistics billboard according to project or material puies forward material program, billboard to be refreshed detail is generated logistics billboard, and billboard is printed, detailed according to the material printed, determine the concrete time of feeding, deliver goods place and deliver goods material, carry out production batching, issuance of materials.Here, deliver goods place is generally each production subsidiary factory, but based on the feature that motor-car is produced, partial material volume is comparatively large, therefore can deliver to the place issuance of materials that production subsidiary factory specifies.This place of specifying is middle database.So namely, ensure that on-the-spot orderly production, also ensure that logistics is prepared burden on time.
Owing to can embody the three daily planning data according to actual production to the billboard data of production subsidiary factory, therefore production subsidiary factory is according to the condition of production of oneself, within one day, assign the detail of the production material of latter three days in advance, system generates according to MRP, product structure information etc. will expect demand billboard, so to the material of production subsidiary factory, by production subsidiary factory according to expecting that request billboard prints outbound list, carry out production batching, issuance of materials process.The material of the subsidiary factory of production here refers to: the intermediate product that recoil material or production subsidiary factory oneself produce.Here intermediate product use to oneself subsidiary factory, also may give next point station-service as material.
Six, billboard flow process, as shown in Figure 4:
1, production subsidiary factory planner assigns the production schedule on the three for one day in advance according to production order and maintenance list, and the production schedule comprised the production material detail of three days on 3rd.
2, system can generate according to MRP, product structure information, stock material information etc. and will expect demand billboard, expect that demand billboard comprises: produce the information such as order, operation, material, quantity, warehouse compartment.
3, all subsidiary factories to expect that demand billboard data summarization gets up to generate lean logistics billboard.
4, after lean logistics billboard generates, according to demand numbering according to item number, teams and groups, operation, row, a packing automatically, generate each production subsidiary factory billboard, each production subsidiary factory billboard is that production subsidiary factory billboard comprises following information: produce the information such as order, operation, work centre, platform position, production team, material, quantity, warehouse compartment according to project, row, the material a generated detail.
What 5, logistics center tally-man provided according to lean logistics billboard and production subsidiary factory planner will expect that demand is carried out: logistics center distributes, pick and join, fill out that storehouse is single, delivery is transferred items and a series of process such as production subsidiary factory issuance of materials, and the content of process comprises: produce the information such as order, operation, material, quantity, warehouse compartment.
