Embodiment
Billboard is formed：Electronic board is formed by coming back with detailed (namely project), and it is the bag in units of order that billboard, which comes back,
The number of collecting containing demand, process route, sequence, record type, work centre, production order number, production order status etc.；Because of billboard
To dispense unit using process as minimum, so detail is in units of process, comprising the demand number of collecting, process route, platform position,
Demand material, factory, stock locations, recoil identify, to expect the specifying informations such as time.The requirement of lean production dispatching is met,
In lean logistics banner system, the new line of billboard is connected with detail by the demand number of collecting.
Work centre in the present invention includes production subsidiary factory and logistics center.
First, billboard generates：
1st, the production schedule of motor-car manufacture is mainly derived from production order and maintenance order (being also maintenance work order), in view of dynamic
The complexity of the car manufacture production schedule and change that may be present, and inevitably engineering design change influences, in logistics
The heart is not taken based on the active means of distribution of stable production schedule arrangement, but take and dispense on demand to the material issuing of production subsidiary factory
Mode proposes to expect demand, it is necessary to produce subsidiary factory based on the production schedule in three days, subsequent production subsidiary factory submit demand personnel according to
According to demand inventory to be expected, with process and/or teams and groups' node, it will expect that the release of demand inventory is submitted to logistics center, and these are given birth to
The transmission of production instruction is all completed by billboard, and the production schedule from maintenance work order directly generates billboard number here
According to, and there was only a pen data from the billboard of maintenance order.
In lean logistics system based on billboard, if multiple billboard, it can write in the table of backstage, be concentrated by background job
Processing.
2nd, billboard generates, and can be divided into backstage automatic running and foreground is formulated by hand
2.1 for priority level it is high, need the billboard of emergent management, foreground can be used to manually enter mode and submit and seen
Plate.When being formulated by hand on foreground, system can judge the quantity of user's input, if the billboard quantity to be run of user's input surpasses
Mistake can be prompted by crossing 100 systems, and this act as being avoided artificial input error, improves the operational efficiency of system.
In process of production, each production order is related to material processing up to ten thousand to 2.2 motor-cars, so dotes on for quantity
Big material, system use the mechanism of parallel processing, are defining method for splitting from the background, system determines generation billboard according to process
Quantity, such as：There are 23 operations on backstage, there is 10 work orders, and each work order has 20 processes, and system can calculate process,
I.e. how many individual billboard quantity, it is that the process in work order calculates, such as each process has 100 kinds of materials, i.e., each work order has
2000 billboard, by all order process data, that is, the data for calculating billboard quantity are needed to carry out cycle labeling into A, B, C, D etc.
23 names (wherein A, B, C, D etc. are job name), during first job run, only take the data that mark is A, second operation
During operation, the data run that mark is B is only taken, by that analogy, because new and old calculating that will be repeatedly per procedure, in ERP, table
Data storage is fewer, and efficiency is higher, so using this mechanism, substantially increases the operational efficiency of billboard, substantially more than ten minutes
Substantial amounts of data run can be made complete；The quantity that certain operation is split is set according to the portfolio of reality, when portfolio
When changing greatly, it can adjust again.Here it is possible to using can perform a plurality of instruction simultaneously or handle multiple data item simultaneously
Single central processing unit computer can also use multiple processor system.
Meanwhile need to calculate weight when mark, this weight is distinguished according to production subsidiary factory, as shown in figure 3,
Because general assembly material accounts for 60% or so of total ratio, so system in background process, can distribute to 60% operation always
Dress, bogie are arranged to 15%, car body design 25%, server resource can be so utilized to greatest extent, with most fast
Speed calculates the quantity of billboard.The distribution of this certain accounting can be adjusted according to the business datum of reality, such as marked
When job name when, if the data of A operation bogie subsidiary factory exceed total amount 25%, the operation that system can automatically to bogie
Next job name is moved on to go to mark.So, effectively by data distribution into 23 background jobs, and reasonably control each
The operation quantity of operation subsidiary factory.The billboard data distribution for ensuring to run out is rational.
2.3 when operation generates billboard detail, and because data volume is larger, the data of billboard are inserted and calculated after being all
Platform Job execution calculates, and so, with practical business there is the time difference, also implies that system is to be generated there is variance data
A computing mark is added in the table detailed into billboard, when operation generates billboard detail, system first can take this, will
The computing mark for generating the data of billboard is set to " X ", after the complete generation billboard detail of system operations, then by computing mark again
It is empty.Using this mechanism, the data for effectively avoiding billboard are calculated by crawl is repeated, the phenomenon hair of generation billboard Data duplication
It is raw.Meanwhile system avoids hash from running to improve the speed of service of billboard, during each run, for production work order
Data are read in again, and are also repeatedly to read in again when reading process data, it is ensured that the data take every time, calculated are all
It is newest, most real-time data, it is ensured that the degree of accuracy that billboard data calculate.
3rd, demand billboard is expected
Production subsidiary factory is submitted according to process and/or teams and groups' node in lean logistics system in the form of billboard to be expected will expect to need
Inventory is sought, is discharged into logistics center.There is the following two kinds form：
1) discrete piece will expect demand inventory：User cannot change quantity required, and the background job of discrete piece is by process
Calculated to be grouped；
2) recoil material will expect demand inventory：User can change quantity required, and simultaneity factor can also simulate calculating and suggest
Quantity required.Here recoil material refers to the unit of materials and the material that forwarding unit is inconsistent, for example paint etc,
The unit of material issuing is tank/bucket, but unit when producing consumption is gram that the actual consumption quantity of usual this material is in life
Production is difficult statistics before completing, therefore the material that recoils is managed in the subsidiary factory storehouse of production subsidiary factory.Logistics billboard operationally, root
The characteristics of expecting according to recoil carries out collecting material issuing.
2nd, the production schedule changes
Produce order, three daily plannings and the possibility of change unavoidably be present, therefore demand billboard to be expected can be caused to produce change
More, system can see if there is outbound record, while original outbound number and demand number are compared according to original material data
Compared with if without outbound, needing quantity to carry out outbound by new material；If outbound records, i.e., cancelling stocks is carried out to raw material,
New materiel warehouse-out, produce one and move back a neck.
The time point that change occurs is probably submit will be before or after material demand.After expecting that demand is submitted, also may be used
It can be picked and match somebody with somebody or done outbound list.
Processing mode is as follows：
The first situation：If concerned process steps node will expect that demand inventory is not submitted or had been filed on but do not pick to match somebody with somebody,
The automatic original that is appended to will expect demand odd numbers (reserved number+record type+process ID+ submits demand sequence number)；
Second of situation：If concerned process steps node to expect demand inventory be submitted and picked with (containing part pick
With), then automatically generate it is new to expect in demand odd numbers (reserved number+record type+process ID+ submits demand sequence number+serial number),
Now, submission will expect demand sequence number, and+1 on the basis of original will expect demand sequence number, to expect demand sequence number initial value here is 1.
3rd, the material returned in demand billboard to be expected is handled
Because producing the change of order, material returned request can be produced, be also developed in system because of practical business demand, Logistics Department
Door actively carries out the function of the material returned and neck material to the material of hair；System supports that one moves back a neck function, that is, applies for the material returned of certain material, can
Apply for the neck material of material mutually tackled simultaneously, also support the material returned of single material, production subsidiary factory needs the production need according to reality
Ask and change and propose report material returned request, logistics tally-man confirms the material returned according to the material issuing situation of reality, such as one moves back a neck, the material returned it is same
When, allot new material, it is ensured that production subsidiary factory, logistics delivery, receive unanimously.
Expect that the material returned in demand billboard there are three kinds of states：Expect the non-outbound of demand, to expect the outbound of demand part, to expect to need
Ask complete outbound, in systems with different fields, different values come accurately calculate in practical business may occur it is various
Material returned demand, such as following table：
Note：For lean logistics system by 6 fields of upper table, three states handle all materials returned being likely to occur
Request, for example,
Represented for ZDSTS_ASS=0：Expect the non-outbound of demand；
Represented for ZDSTS_ISS=1：There is material returned request, material returned request key value and demand to be expected are inconsistent.
There is no this state for " (nothing) " system in upper table, system will not also carry out ZDSTS_ISS=2 or ZDSTS_
CIS=2 is such to be set.
4th, mistake billboard adjustment function
When producing order, maintenance order preservation, the generation of demand schedule to be expected can be triggered, but in the actual industry of motor-car production
, can be because design alteration cause to produce the change of process teams and groups, material, platform position in order in business, the data of billboard want root
Factually border will expect that need state is changed or locked, and billboard data will not be generated after locking, but generate daily record data, note
Record in log sheet, here, the type of daily record includes：Produce work order change, three daily planning changes and MRP change etc..
System is in design, it is contemplated that and all situations of production order variation are specific detailed as follows：
Note：
1) order status is that " X " represents locked, and locked data can not generate billboard data, and be stored in daily record
In table, further processing is waited；
2) it is for the type of order demand change：The state of " increase material " is " (single) ", represents there was only a kind of shape
State, system are directly handled according to need state to be expected,；
3) there are two kinds in the state of " change of process teams and groups "：" mode one " and " mode two ", system are according to circumstances held respectively
OK,
Such as：It is for need state to be expected：" do not submit/or have been filed on but cancel ", " having been filed on not cancelling ", system
Treating method is：Directly change；
It is " completely or partially transferring items " for state to be expected：For what is transferred items, system selection approach one, the work is locked
Sequence, billboard data are not generated, but generate daily record data (subsequent treatment：The material returned request application material returned is first submitted by Ling Liao departments,
After rechange)；For what is do not transferred items, system selection approach two, directly change.
Artificial maintenance mistake that system can will identify that automatically, the locking of production order, material locking, Material Cost are not tieed up
Wrong material billboard data are saved in log sheet caused by the reasons such as shield, design alteration, and when next time is run, system can be automatic right
The data of mistake perform the generation of billboard again, untill this wrong data generation billboard, can just be recorded in error log
This record is deleted in table, it is therefore desirable to periodically start wrong billboard adjustment function, the information flow according to newest production order
Adjust wrong billboard, it is ensured that the promptness of billboard adjustment.
But be not all wrong data for generating daily record, billboard data finally can be all generated, such as：Change recoil
Setting, change material type, change MRP groups, these may cause data run mistake, strictly forbid in systems,
, it is necessary to artificially check when there is this kind of wrong log information.In addition, to expect the project that demand is closed, also will not generation again
Expect billboard, these need to delete by hand.
