Description
Technical field
The present invention relates to computer technology, in particular to data object replacement device and data object alternative method.
Background technology
Enterprise is generally by MRP (Material Requirement Planning, MRP) data objects such as the product of its production, required material is managed, find that after the processing that finishes data object result does not meet actual demand, not enough and can't satisfy the production demand as the material of needs production or buying, at this moment, enterprise substitutes the material that lacks in order to reduce material cost with unclassified stores.Then, manual again each step process result to the data object carries out successively substituting one by one.Because manual alternative workload is big, efficient is low, makes mistakes easily.When application scenarios is complicated, be difficult to guarantee alternative correctness.
Correlation technique provides a kind of data object information amending method, and data object is handled as material, and as shown in Figure 1, it comprises the steps: to detect successively the net demand amount 102 of each material; When the net demand amount that detects arbitrary material is non-vanishing, search the replaced material corresponding alternative material 104 non-vanishing with the net demand amount according to substitutional relation information and material available stock amount; According to the Bill of Material (BOM) information of replaced material, substitute percent information and the available stock amount of the alternative material that finds, revise the net demand amount of replaced material and relevant stage material down and the available stock amount 106 of the alternative material that finds.
Though said method can be revised the information of data processing object, can't the processing of classifying of the plurality of application scenes of enterprise be caused alternative method to be difficult to be applied in the reality and go.
At first, it can't for example be handled respectively the alternative wish of different material:
1. when object lacks, carry out automatic alternate process at once.
2. when object lacks, judge whether and in time to supply, if can in time supply, just do not adopt alternative object to carry out alternate process.
3., then do not do data processing if not wishing to carry out substitutes automatically.
Secondly, when substituting generation, can't judge the multiple situation that may occur, underaction seems under the application scenarios below.
1. adopt a kind of object to carry out alternate process.Guarantee unanimities such as feasible color, attribute in processing procedure with a collection of product.
2. can use multiple object to carry out alternate process.May use yellow, the object of multiple color such as redness substitutes original blue object.
3. after an alternate process takes place, do not re-use and substitute object as the supply deal with data.For example: enterprise uses 15 cun old money display as the accessory of computing machine always, when 15 cun display stocks use the light time, do not re-use 15 cun display, and use 17 cun display instead, the display that perhaps uses 17 cun, 19 cun simultaneously is as the supply object.
Once more, alternative logic and parameter cannot be set at different levels.
1. for a kind of object, adopt a kind of alternative object all the time.
2. for a kind of multiple BOM (Bill of Material) structure of object, adopt different alternative objects.
Based on the defective in the correlation technique, need a kind of data object substitute technology, not only can avoid inefficiency of manually bringing and the problem that error may occur, it is also conceivable that different application scenarioss, make the alternate process of object become flexible.

In technique scheme, preferably, can also comprise: second judge module 208, being used in alternative is that replaced object is preferential, and under the situation that replaced object can not be supplied on time and preferential for substituting object in alternative, use the replaced object that substitutes after object substitutes to also have under the situation of net demand amount, judge the alternative control mode of replaced object.
In technique scheme, preferably, object alternative module 206 can also comprise sequencing unit 2064, is used for according to the order of priority each alternative object being sorted; And computing unit 2066, the stock who is used to search each alternative object calculates the demand of each alternative object successively according to the order of priority, and wherein, the demand that substitutes object is the product of the alternative ratio of the net demand amount of replaced object and alternative object;
Data object replacement device 200 can also comprise: modified module 210 is used for revising the relation between supply and demand of replaced object when the object alternative module is carried out substituting of replaced object according to the alternative control mode of judging after.
In technique scheme, preferably, judge that at second judge module 208 substituting control mode is under the situation of replacing whole, whether the stock who judges same alternative object successively satisfies corresponding demand, when judged result when satisfying, then the object alternative module substitutes replaced object with same alternative object, when judged result when not satisfying, then object alternative module 206 does not substitute, order according to priority is carried out judgment processing to the alternative object of the next one, if the stock of each alternative object all can not satisfy corresponding demand, then demand document generation unit 2062 generates the demand document of replaced object; Judge that at second judge module 208 substituting control mode is under the alternative situation of part, object alternative module 206 substitutes replaced object successively according to the order of the priority that substitutes object, if the replaced object after substituting also has the net demand amount, then demand document generation unit 2062 generates the demand document of replaced object; Judge that at second judge module 208 substituting control mode is under the situation of replacing, object alternative module 206 substitutes replaced object successively according to the order of the priority that substitutes object, if the replaced object after substituting through all alternative objects also has the net demand amount, then demand document generation unit 2062 generates the demand document of last alternative object that substitute and modified module 210 and replaced object is replaced to the alternative object that last substitutes in object inventory structure.If it is replaced to liking A, alternative object B, C are arranged, carry out substituting according to the alternate orders of C behind the first B so to the A object, if the stock of B can not satisfy the net demand amount of A, the A object does not just have the net demand amount after needing after B substitutes to continue C substituted, is the C object with the A object modification in the BOM structure then, with the C object as appointed object, just generate later the demand document that C substitutes object, from then on do not re-use the A object.
For the principle of clearer data object replacement device of the present invention, come the exemplary concrete technical scheme of explanation with concrete application scenarios below.Should be appreciated that at this object that data object replacement device is handled can be a material.
Object supply and demand ratio in the data object replacement device is retrieved all demands and the supply of 202 pairs of each objects of retrieval module, and which definite demand can use supply, and the demand that can't satisfy is a net demand.
A. the object supply and demand ratio is as shown in table 1 below to the demand supply data of retrieval module 202 collections:
| Object | Type | The supply and demand type | The demand supply | The project dimension |
| Hyundai Motor EL01 | Sales order | Demand | 100 | Project A |
| Hyundai Motor EL01 | Produce order | Supply | 30 | Project A |
| Hyundai Motor EL01 | The stock | Supply | 50 | Item B |
| Hyundai Motor EL01 | The stock | Supply | 60 | Project A |
| Hyundai Motor EL02 | The stock | Supply | 20 | Project C |
Table 1
B. the object supply and demand ratio is to the supply requirement comparison logic of retrieval module 202.
According to last table 1 process object " Hyundai Motor EL01 " at first, specifying information is: demand sales order 100, project dimension are project A, all supplies of search terms A.Produce order 30, the stock 60.The project dimension be the item B correspondence Hyundai Motor EL01 and to as if the supply data of Hyundai Motor EL02 cannot use.
So, the object supply and demand ratio can detect net demand amount=100-30-60=10 of Hyundai Motor EL01 to retrieval module 202, therefore, also needs regeneration to produce the car of 10 models for " Hyundai Motor EL01 ", project dimension A.
Object alternative module 206 can define substitutional relation on object and two levels of BOM, carry out the data processing that corresponding object substitutes according to three kinds of alternative and three kinds of alternative control modes of providing.
Processing procedure under three kinds of alternative:
(1) be that (replaced object is replaced object under the preferential situation of replaced object if first judge module 204 is judged alternative, the promptly original object that needs), if replaced to as if when making part, continue to judge whether replaced object can in time be supplied, if before the Date Required of replaced object, still can't in time supply, then just consider to use to substitute object.Under this scene, the user wishes to reduce the use that substitutes object as far as possible.
(2) if it is to substitute under the preferential situation of object that first judge module 204 is judged alternative, when replaced object has the net demand amount, substitute according to the corresponding control mode that substitutes.Under this scene, the user wishes to use other objects to substitute replaced object.
(3) if it is not have under the situation about substituting that first judge module 204 is judged alternative, do not consider to substitute when then MRP calculates, can ignore yet even defined to substitute.
With table 2 concrete data handling procedure under three kinds of alternative is described below.
| Object | Type | The supply and demand type | The demand supply | The ratio of substituting |
| Silver paint LT01 | Satisfy sales order | Demand | 100 | 1 |
| Silver paint LT01 | Produce order | Supply | 40 | 1 |
| Silver paint LT01 | The stock | Supply | 30 | 1 |
| Silver paint LT02 bottle | The stock | Supply | 50 | 2 |
| Blue lacquer LT01 | The stock | Supply | 100 | 1 |
Table 2
Produce 100 " Hyundai Motor EL01 " as needing in the table 1, producing these 100 cars needs 100 bottles of silver paint LT01.The object supply and demand ratio is collected all demands supplies to retrieval module 202, and it is right to carry out supply and demand ratio.Information from last table 2, object supply and demand ratio can detect net demand amount=100-40-30=30 bottle of silver paint LT01 to retrieval module 202.That is to say, also need 30 bottles of silver paint LT01.At this moment, first judge module 204 is just judged the alternative of object silver paint LT01.
A. be the object of silver paint LT01 when preferential when the data object replacement device adopts the preferential alternative of replaced object, then need regeneration to produce 30 bottles of silver paint LT01, demand document generation unit 2062 generates the demand document of silver paint LT01.
B. when the data object replacement device adopt to substitute the preferential alternative of object, can use " silver paint LT02 bottle " to substitute, but can substitute one bottle " silver paint LT01 " according to 2 bottles of alternative ratios " silver paint LT02 ", 50 bottles only to substitute 25 bottles " silver paint LT01 " so.Like this, after employing " silver paint LT02 bottle " substitutes, net demand amount=100-40-30-50/2=5 bottle of silver paint LT01.
Continuation is that example is come the data handling procedure of description object replacement device three kinds of alternative control modes with table 2.
Concrete alternative control mode is as follows:
(1) be under the situation of replacing whole in alternative control mode, all alternative objects are sorted according to the corresponding priorities order, the data object replacement device is handled alternative object one by one according to priority orders, during processing, calculate earlier the demand of each alternative object, demand is the product of the alternative ratio of the net demand amount of replaced object and alternative object.What substitute object detects the demand whether same alternative object supply sum can satisfy the alternative object that calculates successively according to ranking results, if can not satisfy then abandon this alternative object, whether the supply sum that continues next alternative object of detection can satisfy the demand that substitutes object, till finding satisfiable alternative object, if all alternative objects all can not satisfy the supply of replaced object, generate the demand document of replaced object so.
(2) be under the alternative situation of part substituting control mode, can adopt multiple different object to substitute.All alternative objects are carried out prioritization, also be to handle substituting object one by one according to priority orders, during processing, also need to calculate the demand of each alternative object, successively replaced object is substituted, if also have unsatisfied net demand, then generate the demand document of replaced object.
(3) substituting under the situation of control mode for replacement, all alternative objects are carried out prioritization, handle substituting object one by one according to priority orders equally, when handling, need to calculate the demand of each alternative object equally, successively replaced object is substituted, if alternative this replaced object afterwards through all alternative objects also has unsatisfied net demand amount, then generating the demand document of last alternative object that substitutes and will substituting object modification is getting the raw materials ready in the object inventory structure, when the data object of data object replacement device processing is material, then this object inventory structure is Bill of Material (BOM) (BOM) structure, that is to say in Bill of Material (BOM) (BOM) structure replaced material is replaced to the alternative material that last substitutes.Need to prove, revise after the object relationship in the object inventory structure, to use the object of appointment later on, under the situation that replacing whole and part substitute, do not need to revise getting the raw materials ready in the object inventory structure, that is to say after alternative Process finishes, also be to use original data object later on.
As in the table 2, when adopting the preferential alternative of replaced object, replaced object also has net demand amount=100-40-30=30 bottle.
A. when the data object replacement device adopts the alternative control mode of replacing whole, then cannot use " silver paint LT02 bottle " and " blue lacquer LT03 " to substitute simultaneously, and use " silver paint LT02 bottle ", not satisfy 30 demand only to substitute 25 bottles.So can only adopt " blue lacquer LT03 " to substitute.
B. when the data object replacement device adopts the alternative control mode that partly substitutes, can use " silver paint LT02 bottle " to substitute 25 bottles, re-use " blue lacquer LT03 " and substitute remaining amount 100-40-30-50/2=5 bottle.
Fig. 3 shows the process flow diagram of data object alternative method according to an embodiment of the invention.
As shown in Figure 3, the data object alternative method comprises according to an embodiment of the invention: step 302, object supply and demand ratio detect the net demand amount of each object successively to retrieval module; Step 304, when the net demand amount that detects object was non-vanishing, first judge module was judged the alternative of object; Step 306, the object alternative module is carried out substituting of object according to the alternative of judging.
In technique scheme, preferably, step 306 can comprise: step 3062, when alternative is that replaced object is when preferential, judge under the situation that replaced object can supply on time at first judge module, demand document generation unit generates the demand document of replaced object, and wherein, replaced object is the non-vanishing object of net demand amount and is the manufacturing part; Step 3064, when alternative when not substituting, demand document generation unit generates the demand document of replaced object; Step 3066, when alternative for substituting object when preferential, the object alternative module is used and is substituted object and substitute replaced object.
In technique scheme, preferably, can also comprise step 308, second judge module is judged the alternative control mode of replaced object, the object alternative module is carried out substituting of replaced object according to the alternative control mode of judging; In step 3062,, carry out step 308 judge under the situation that replaced object can not supply on time; In step 3066, the replaced object after substituting also has under the situation of net demand amount, carry out step 308.
In technique scheme, preferably, step 308 can also comprise: sequencing unit sorts to each alternative object according to the order of the priority that substitutes object, computing unit is retrieved the stock of each alternative object, calculate the demand and the object alternative module of each alternative object according to the order of priority successively and carry out substituting of replaced object according to the demand of alternative object and the stock of alternative object, modified module is revised the relation between supply and demand of replaced object, wherein, the demand that substitutes object is the product of the alternative ratio of the net demand amount of replaced object and alternative object.
In technique scheme, preferably, in alternative control mode is under the situation of replacing whole, whether the stock who judges same alternative object successively satisfies corresponding demand, when judged result when satisfying, then same alternative object is substituted this replaced object, when described judged result when not satisfying, then do not substitute, order according to described priority is carried out judgment processing to the described alternative object of the next one, if the stock of each described alternative object all can not satisfy corresponding demand, then described demand document generation unit generates the demand document of described replaced object; Substituting control mode is under the alternative situation of part, time described replaced object is substituted according to the order of the described priority of described alternative object, if the described replaced object after substituting also has the net demand amount, then described demand document generation unit generates the demand document of described replaced object; Substituting under the situation of control mode for replacement, described object alternative module substitutes described replaced object successively according to the order of the described priority of described alternative object, if the replaced object of replaced object after substituting through all alternative objects also has the net demand amount, then generate the demand document of last alternative object that substitutes and modified module and in object inventory structure, replaced object replaced to the alternative object that last substitutes.
Continuation illustrates technical scheme of the present invention with Fig. 4, Fig. 5, Fig. 6 and Fig. 7, Fig. 4 shows the process flow diagram of data object alternative method according to an embodiment of the invention, Fig. 5 shows according to an embodiment of the invention at the synoptic diagram of expecting that the definition object substitutes on the product archives, and Fig. 6 shows synoptic diagram and Fig. 7 that the definition object substitutes on the BOM subitem according to an embodiment of the invention and shows the synoptic diagram of plan of needs calculating according to an embodiment of the invention.
At first, if the user wants that consideration substitutes when carrying out the data object plan of needs, and use the inventory data that substitutes object as supply data automatically, necessary predefined substitutional relation comprises the ratio that substitutes object, substitutes the order of object.
The order that substitutes object often has a plurality of optional object datas exactly when object substitutes, the user can be provided with the priority orders that substitutes object.When substituting, consider earlier the supply data of high object of priority,, consider the object data that priority is low again if can't satisfy.
The ratio that substitutes object is exactly that the user often wishes proportionally replaced object to be substituted in reality substitutes.For example,, can use yellow and viridine green, mix substituting according to a certain percentage if when not having blue pigment.
Alternative definitions occurs on two levels:
1) object layer: definition substitutes object, alternate orders, substitutes ratio on the object archives, is called object and substitutes, as shown in Figure 5.
2) BOM layer: definition substitutes information such as object, alternate orders, usage ratio, alternative control mode on the BOM subitem, is called BOM and substitutes.Same target can define different alternative objects under different BOM structures.When carrying out the data object alternate process, consider that earlier BOM substitutes, consider that again object substitutes, as shown in Figure 6.
Whether the net demand amount that step 402, object supply and demand contrast retrieval module detect each object successively is zero, when judged result for not the time, carry out step 404, when judged result when being, then flow process is restarted.Whether earlier demand was sorted by the demand date, pay the utmost attention to Date Required demand the earliest, judging then had enough supplies to satisfy before Date Required, supply data comprises the stock, produced order, data such as purchase order.If can satisfy, judge the next record demand, if can't satisfy, think that there is the net demand amount in this object.
Step 404 continue to judge that the net demand amount is the alternative of zero object, when alternative when alternative, then carry out step 410,, then carry out step 408 when alternative is that replaced object is preferential and when making part, when alternative for substituting object when preferential, then carry out step 406.
Step 406 when replaced object has the net demand amount, enters the logical process that substitutes control mode, enters step 412 then.
Step 408 judges whether replaced object can be supplied on time, when judged result for not the time, carry out step 410, when judged result when being, carry out step 412.
Step 410 does not substitute replaced object, produces the demand document of replaced object.
Step 412 judging that substituting control mode is under the situation of replacing whole, carry out step 418, and substituting control mode in judgement is under the situation about partly substituting, and carry out step 416, judging under the situation of alternative control mode for replacement, carry out step 414.
Step 416 is carried out the ordering of priority to substituting object, successively replaced object is substituted, if also have unsatisfied net demand amount, generates the demand document of replaced object.
Step 418, carry out the ordering of priority to substituting object, and judge successively whether same alternative object can satisfy the net demand amount of replaced object, if can not satisfy, then abandon this object data, continuation if all alternative objects all can not satisfy the net demand amount of replaced object, then generates the demand document of replaced object in like manner to handle next object data.
Be noted that,, all need handle one by one substituting object, and calculate the demand that substitutes object that demand is the product of the alternative ratio of the net demand amount of replaced object and alternative object according to priority orders no matter be which kind of substitutes control mode.Not to calculate entirely the demand of all alternative objects is disposable simultaneously, but, just calculate the demand of which alternative object, can avoid the waste of computing time when which being handled when substituting object; As the stock who substitutes object during greater than demand, under three kinds of alternative control modes, all substitute, as the stock who substitutes object during less than demand, in control mode is under the situation of replacing whole, do not substitute, next object is handled, and is under the situation that partly substitutes and replace in control mode, substitutes according to priority orders; When all alternative objects fail to satisfy the net demand amount of replaced object, generate the demand document that substitutes object, especially, under the situation of control mode for replacement, the appointment that needs to revise the upper level object of replaced object in the BOM structure is got the raw materials ready, after revising, original object will do not re-used.
Fig. 8 shows the BOM structural representation of object A according to an embodiment of the invention, continues with the concrete example of Fig. 8 technical scheme of the present invention to be described.
Enterprise receives a sales order, needs to produce 100 A objects, enquiry on the 20th.The A object is by 1 B, and 2 C are assembled, and makes part B and is assembled by 2 D and 3 E, as shown in Figure 8.D, C, E are Purchased Items, need to buy.At present, for making part, enterprise wishes that oneself is produced as far as possible, few substituting, and the data object replacement device has adopted the alternative of " replaced object is preferential ".C when the stock does not satisfy, can adopt C1 to liking Purchased Item, and C2 comes to substitute simultaneously, has adopted the alternative control mode of " part substitutes ".Make part B, when the stock does not satisfy, can adopt B1 to substitute, adopt the alternative control mode of " replacing whole ".D makes raw material, needs buying, can use D1 to substitute, and adopts the alternative control mode of " replacement ".Suppose that the alternative ratio of all objects all is 1.
The alternate process process of data object replacement device of the present invention is as follows:
1) object supply and demand comparing module 202 detects the net demand amount of each object successively, at first retrieves all supply requirement data of A object.Find that sales order needs 100 of A objects, the stock is 40 at present, and calculating the net demand amount is 100-40=60.Calculate rank objects (next stage object) demand down, need 60 of B objects, need 120 of C objects.Enter the computing of next object.
2) detect the B object, detect 60 of demand data, do not have inventory data, then calculate 60 of net demand amount data.At this moment, because first judge module 204 judges that the alternative of these B objects be " replaced object is preferential ", and the B object is for making part, if consider oneself production B object, whether can satisfy 20 days delivery date of A object.Find and oneself to produce through calculating.Calculate rank object-oriented requirements down, need 120 of D objects, 180 of E objects.
3) detect the C object, detect 120 of demands, do not have inventory data, then calculating the net demand amount is 120.At this moment the C1 stock 50, and C2 stock 60 because second judge module is judged the alternative control mode that this object adopts " part substitutes ", can consider C1, the stock of C2 simultaneously.After object alternative module 206 is used the C1 alternate process, calculate net demand amount 120-50=70 in addition, consider the stock of C2 again, after substituting, also have net demand amount 70-60=10, then the planned order of demand document generation unit 2062 generation object C is 10, promptly also needs to purchase 10 object C again.
4) continue to detect the D object, detect 120 of demand data, do not have inventory data, then calculating the net demand amount is 120-0=120.Considering to substitute logic, is " replacement " owing to substitute control mode, 150 of D1 object stocks, and the net demand amount greater than calculating can substitute.Simultaneously, modified module 210 is revised the BOM structure of B object, does not re-use the D object as getting the raw materials ready, with D1 object getting the raw materials ready as the B object.
5) detect the E object, detect 180 of demand data, 200 of inventory datas, supply does not have the net demand amount greater than demand.
When the object of data objects processing device processing was material, then shown in Figure 8 was Bill of Material (BOM) (BOM) structure of material A.
In the calculating of data object plan of needs, the user can repeatedly calculate in different plan versions, and a plurality of result of calculations are compared.In different plan versions, the user can select different alternative.Like this, can be in conjunction with the actual replacement scheme that obtains optimum.
Below in conjunction with the accompanying drawings technical scheme of the present invention is had been described in detail,, can assist enterprise that object data is managed by technical scheme of the present invention.
1) improves the efficient of enterprise to the data Object Management group.Calculate substituting of realization data object automatically by MRP, greatly reduce personnel cost.
2) reduce enterprise's production cost, be provided with by reasonably substituting, enterprise can adopt the lower object of cost to produce.
3) shorten the production cycle, by rational calculating, the shortest object time in advance that enterprise can adopting, thus shorten produce the time in advance.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
