Pay pack pattern calculating part 3 and pay meter first by the parts obtained from parts delivery schedule database 11
Draw information parts number and from case sized data storehouse 12 obtain case dimension information can be accommodated in case in parts
Quantity, generation indicates every day pays the information of how many case.Then, paying pack pattern calculating part 3 will be from product packaging condition
The product packaging conditional information that database 13 is obtained carries out three-dimensional simulation as restriction condition, attempts the group of various casees
Close, for example, calculate pack pattern according to each supplier（Pallet numbers）So that pallet numbers are minimum.For example, the packaging sample of D days
Formula is as follows：Supplier A：30 trays, supplier B：50 trays, supplier C：20 trays.
Additionally, in the case where case species is few, paying pack pattern calculating part 3 can not also implement above-mentioned three-dimensional simulation,
By the volume 1m of case3It is considered as a tray, estimates pallet numbers.In addition, in the case where daily production changes less, paying bag
Dress pattern calculating part 3 can also be based on empirical pallet numbers using by field investigation.
Pay the payment pack pattern that pack pattern calculating part 3 will be deduced（The pallet numbers of each supplier）As fortune
Defeated object information, stores in object of transport database 14.Additionally, pay pack pattern calculating part 3 can also be not via transport
Object database 14 and directly by transport amount calculating part 4 in object of transport information output to factory.
Transport amount calculating part 4 is a concrete example of workload computing component in factory, based on from pay the order of classes or grades at school moment
Table information that table database 9 is obtained and the object of transport information obtained from object of transport database 14 calculate each transport
The workload of time-bands（The freight volume of tray）.In factory transport amount calculating part 4 first by from pay time table of runs number
Fortune time when the table information obtained according to storehouse 9 is transported to set with predetermined time interval.Then, haulagman in factory
The pallet numbers of the object of transport information that work amount calculating part 4 will be obtained from object of transport database 14 are assigned to each fortune time.With
Under one in, following methods are illustrated：By 1 day with stipulated number（For example, fortune time #1~fortune time #12）Decile, with
The predetermined time interval transports the parts of delivered to production plant to the production line of production plant.
Fig. 3 is the figure of that represents the relation table being indicated to the relation of supplier and haulage time.In figure 3,
For example, fortune time #1 is 8：00 starts transport, and fortune time #2 is 9：00 starts transport, and fortune time #3 is 10：00 starts transport, fortune
Secondary #4 is 11：00 starts transport.
Transport amount calculating part 4 generates the relation table of as described above, supplier and haulage time in factory.Transported in factory
Workload computing portion 4 is calculated when which is transported first by from the table information that time table of runs database 9 is obtained is paid
Between（Fortune time #1~fortune time #12）The goods of which supplier A, B, C can be transported.
For example as shown in figure 3, in the payment time table of runs of supplier C, goods and can be to life is unsnatched from lorry
Producing line starts the time of transport it is assumed that 8：30、11：30、14：30、17：30.In this case, can be by the cargo transport time
It is assigned to fortune time #2, #5, #8, #11 in factory（The zero of Fig. 3）.
Then, transport amount calculating part 4 is real for each zero in the relation table of above-mentioned supplier and haulage time in factory
Apply the distribution of the multiple trays paid from each supplier A, B, C（Fig. 4）.It is assumed here that many by what is paid from each supplier A, B, C
Individual tray is positioned on multiple chassis, links the situation that each chassis is transported respectively.In addition, for example, 1 chassis loads 1
Tray.
For example, in the case where a people can once carry out 6 chassis of transport, as shown in figure 4, the transport of fortune time #1 makes
With 12 chassis, therefore, it is known that if being transported with two people, efficiency is best.In addition, workload is used " once as described above
The chassis quantity that can be transported " is showed, but is not limited to this, for example, it is also possible to use " time needed for a hauling operation "
To show.In this case, in factory transport amount calculating part 4 using the running time of each chassis in hauling operation and from each
Chassis is to the time needed for production line supply parts case（Supplying 1 case needs several seconds etc.）To calculate haulage time each time.
The workload information that transport amount calculating part 4 will be computed as described above out in factory is stored in workload database 15.
It is the concrete example that resource minimizes component that resource minimizes processing unit 5, based on being taken from workload database 15
Optimal condition information of the workload information and storage for obtaining in optimal condition database 16, is carried out at resource minimum
Reason, resource minimum treatment is suitably postponed（Postpone）While haulage time, calculate turned into few optimal of deviation in 1 day
The transport project information of transport resource.Optimal condition database 16 is stored with needed for carrying out resource minimum described later treatment
Various optimal condition information.
The transport project information Store that resource minimum processing unit 5 will be calculated is in transport project database 17 in factory.
The transport project information stored in transport project database 17 in factory is output by output section 18.Transport project information is for example
It is used as transport instruction by printer etc. to be output with file, or is shown by display device.In addition, resource minimum is processed
In the treatment of above-mentioned resource minimum, the time that will be postponed stores the safety in factory as safety inventory temporal information in factory in portion 5
In inventory time database 10.Additionally, resource minimum processing unit 5 can also be not via safety inventory temporal database 10 in factory
And directly by safety inventory temporal information output in factory to payment pack pattern calculating part 3.
Additionally, production schedule database 6, constituent parts database 7, parts order terms database 8, payment order of classes or grades at school
Safety inventory temporal database 10 in schedule data base 9, factory, parts delivery schedule database 11, case sized data storehouse 12,
In product packaging condition database 13, object of transport database 14, workload database 15, optimal condition database 16 and factory
The split of transport project database 17 ground is constituted, but is not limited to this, it is also possible to is arbitrarily combined and is integrally formed.In addition, each
Database 6,7,8,9,10,11,12,13,14,15,16,17 can be arbitrary by such as disk set, optical disc apparatus, RAM etc.
Storage device is constituted.
Hereinafter, the resource minimum treatment for being carried out to minimizing processing unit by resource is described in detail.Fig. 5 be represent by
Resource minimizes the flow chart of of the resource minimum handling process that processing unit is carried out.
Resource minimizes the fortune time that processing unit 5 retrieves remaining chassis minimum number（Step S1）.Resource minimizes processing unit 5
For example remaining chassis quantity is calculated using following formula.Additionally, in following formula, MOD（A, b）It is the letter of remainder when obtaining a divided by b
Number.Remaining chassis quantity=MOD（The chassis quantity of each fortune time, the chassis quantity that a people can once be transported）, such as schemed
Shown in 4, in fortune time #3, in the case where the chassis quantity that can be once transported is 6, remaining chassis quantity=MOD
（11,6）=5.Resource is minimized processing unit 5 and the remaining chassis quantity of each fortune time is calculated using above formula, and retrieves remaining chassis quantity
Minimum fortune time, the fortune that will be retrieved time is set as variable " fortune time ".
Resource is minimized processing unit 5 and chassis is for example selected in units of supplier in each fortune time（Step S2）.Resource is most
Chassis of the smallization processing unit 5 for example preferentially from the few supplier of the occurrence number of every day is selected.In the situation shown in Fig. 4
Under, the chassis with supplier A（Occur 12 times）Compare, resource minimizes the chassis of the prioritizing selection supplier B of processing unit 5（Occur 6
It is secondary）, the chassis with supplier B（Occur 6 times）Compare, the chassis of prioritizing selection supplier C（Occur 4 times）.
Resource minimizes processing unit 5 and judges whether the chassis of the above-mentioned steps selected suppliers of S2 " tries movement（Not
The postponement being determined）" or it is " mobile（The postponement being determined）”（Step S3）.Here, postponement refers to the time for transporting chassis
From the fortune time to next fortune time passage.
Chassis also not " the examination movement that processing unit 5 is judged to selected supplier is minimized in resource（Attempt postponing）" or
Person is " mobile（It is determined that postponing）" when（Step S3's is no）, shifted to the treatment of following step S4.On the other hand, minimized in resource
Processing unit 5 be judged to the chassis of selected supplier " examination movement " and " movement " when（Step S3's is）, return to
State the treatment of step S2.Additionally, in fig. 5 it is shown that perform the example once postponed, but it is not limited to this, it is also possible to perform
Postponement more than twice.
Resource minimizes the postponement that processing unit 5 performs the haulage time of chassis of the passage in units of supplier（Step
S4）.Thereby, it is possible to carry out the adjustment of the workload of unit interval.Additionally, for the chassis of same supplier, maintaining fortune
Above-mentioned postponement is performed in the state of defeated interval.
For example, as shown in fig. 6, in the case where postponement is performed for certain chassis, for the chassis of same supplier, also existing
Maintain in the state of its transport interval, equally spaced perform postponement.That is, resource minimizes processing unit 5 from equally spaced fortune
Only make identical number of units in the chassis transported in secondary #1, #3, #5（In this case it is 1）Chassis postpone till next fortune
Secondary #2, #4, #6.
Like this, keeping performing postponement in the state of transport interval is constant, thereby, it is possible to always at certain intervals will
Parts are supplied to production line.In addition, on a production line, in the case that parts are always spaced by use with identical transport,
As long as remaining a certain amount of safety inventory.
In addition, when resource minimizes the postponement of the execution chassis of processing unit 5, being performed preferably in units of supplier.This be because
To be indicated, it is necessary to send transport when being transported based on implementing plan.Now, the pallet tags subsidiary by observing tray itself
Supplier column or the subsidiary supplier column of case, can simply judge whether be postpone object chassis.Additionally, resource is minimum
Change processing unit 5 and postponement is performed in units of supplier, but be not limited to this, it is also possible to postponed with arbitrary unit.
Resource minimizes processing unit 5 and sets up " trial " for performing the chassis in units of supplier of above-mentioned postponement
Mark（Step S5）.
Resource minimize processing unit 5 judge as perform above-mentioned postponement result, transport number of times whether become than always transport
Defeated number of times is small（Step S6）.For example, in the figure 7, when the chassis quantity that a people can once be transported is 5, required money
Source turns into total 9 people, and total transport number of times turns into 9 times.When postponement is performed in the state of the Fig. 7, as shown in figure 8, required resource
As total 6 people, total transport number of times turns into 6 times.Therefore, resource minimizes processing unit 5 and is judged to as performing above-mentioned postponement
Result, total transport number of times is reduced to 6 times from 9 times.
Resource minimizes processing unit 5 and is judged to become than total transport as performing the result of above-mentioned postponement, transport number of times
Secondary a few hours（Step S6's is）, shifted to the treatment of following step S9.On the other hand, resource minimizes processing unit 5 and is judged to
As the result of above-mentioned postponement, transport number of times is performed time a few hours are transported unlike total（Step S6's is no）, to following step S7
Treatment transfer.
Resource minimizes the following situation of processing unit 5 pairs and judges：By performing above-mentioned postponement, in the chassis number of each fortune time
In amount, whether minimum chassis quantity and the difference of the chassis quantity of maximum diminish（Step S7）.Resource minimizes processing unit 5 and judges
For：By performing above-mentioned postponement, in the chassis quantity of each fortune time, minimum chassis quantity and the difference of the chassis quantity of maximum become
When small（Step S7's is）, shifted to the treatment of following step S9.On the other hand, resource minimizes processing unit 5 and is judged to：It is logical
Cross and perform above-mentioned postponement, in the chassis quantity of each fortune time, minimum chassis quantity and the difference of the chassis quantity of maximum do not become
Hour（Step S7's is no）, shifted to the treatment of following step S8.
For example, in fig .9, when the chassis quantity that a people can once be transported is 5, required transport resource turns into
Total 9 people, total transport number of times turns into 9 times, and it is the difference of 3 as 4 with minimum chassis quantity that maximum chassis quantity is 7
Platform.When postponement is performed in the state of the Fig. 9, as shown in Figure 10, required transport resource turns into total 9 people, always transports number of times
It is constant as 9 times, but the chassis quantity of maximum to be 6 and minimum chassis quantity diminish for the difference of 4 turns into 2.Cause
This, in shown in Fig. 9 and Figure 10, by performing above-mentioned postponement, in the chassis quantity of each fortune time, minimum chassis number
The difference of amount and maximum chassis quantity diminishes, therefore, resource minimizes processing unit 5 using the transport mould shown in Figure 10 now
Formula.Additionally, in above-mentioned one, postponing 1 chassis, but be not limited to this, it is also possible to postpone many chassis.
In step s 8, even if resource minimizes processing unit 5 and performs above-mentioned postponement as described above, its Transportation Model does not also change
It is kind, therefore, the postponement temporarily interrupted the trial postponed and attempt next supplier, so as to return to the place of above-mentioned steps S2
Reason.Even if additionally, resource minimizes the postponement that processing unit 5 performs the entire cargo that there is possibility, performing step S8's
In the case for the treatment of, the treatment of above-mentioned steps S1 is also returned to.
In step s 9, resource minimizes the treatment that processing unit 5 is determined the postponement of above-mentioned execution.Resource minimum treat
The value of current transportation number of times is substituted into total transport number of times by portion 5, and removes the mark of " trial ".Resource minimizes processing unit 5
Shorten the calculating time, in the case of the postponement for improving Transportation Model has been performed as described above, determine the postponement, and return to above-mentioned
The treatment of step S1.
Additionally, resource minimizes processing unit 5 being attempted with the few order execution postponement of remaining chassis quantity in each fortune time.Example
Such as, when the chassis quantity that a people can once be transported is 5, resource minimizes processing unit 5 and eliminates remaining chassis first
Quantity is the fortune time of 1, then, eliminates the fortune time that remaining chassis quantity is 2, eliminates the fortune time that remaining chassis quantity is 3,
And the fortune time that remaining chassis quantity is 4 is eliminated, perform to postpone in this way and attempt.Like this, the few fortune of remaining chassis quantity
Secondary the probability that can reduce total transport number of times is high compared with the fortune time more than remaining chassis quantity, therefore, it is possible to will more quickly solve
Convergence.
Resource minimizes processing unit 5 and is repeated after the treatment of above-mentioned steps S1~step S9, performs whole postponements
（Step S10's is）, when judging to meet the termination condition of regulation（Step S11's is）, the treatment of ending resource minimum.Additionally,
Resource is minimized on processing unit 5 can also terminate after the above-mentioned calculating for having carried out stipulated number or with the time being determined
Calculating is stated, and ending resource minimum is processed.Processed by performing this resource minimum, connect transport trolley quantity each time
The higher limit of the chassis quantity that a nearly people can once be transported so that total transport number of times is reduced.Therefore, it is possible to reduce transport
Resource.Resource minimum processing unit 5 for example will as described above carry out transport project information in the factory of resource minimum treatment and lead to
Output section 18 is crossed to be shown as file, signal and exported, or automatic equipment to transport etc. sends instruction.Specifically,
By the instruction for for certain supplier transported with the haulage time of which time, people or equipment can make the supply of material of object
The tray of business is moved in the track and standby of setting out of this time in time.
In addition, now resource minimizes the safety inventory time that processing unit 5 is calculated in factory.Transported postponing, delaying
In the case of the haulage time of defeated tray, when being observed from production line side, the arrival of parts correspondingly postpones.Accordingly, as
Stock, as long as correspondingly ensuring parts with the retardation, it becomes possible to improve the not enough security of reply parts supply.Example
Such as, when each fortune time was at intervals of 1 hour, in the case where haulage time once has been postponed, preferably by the zero of the amount of 1 hour
Part keeps as safety inventory, turns into the safety inventory time within this 1 hour.Resource minimizes processing unit 5 and is performing as described above
In the whole parts postponed, the safety inventory time as described above is calculated, and store as safety inventory temporal information
In safety inventory temporal database 10 in factory.
Pay and indicate calculating part 2 to indicate to start until to untill actual production plant's payment, examination being paid since output
Time（The outer logistics lead time that logistics typically between supplier and production plant spends）On, add production plant and test
Receive the time of backward production line transport（The logistics lead time in factory）, and then plus the above-mentioned safety inventory time for calculating.By
This, can from a production line use parts time, it is contemplated that the required time, carry out inverse operation, thus exactly with
The appropriate time carries out payment instruction to each supplier.It is minimum thereby, it is possible to implement the transport resource in JIT production planning and factory
Payment indicate.That is, can optimize transport resource.
Additionally, this invention is not limited to above-mentioned implementation method, can suitably be changed in the range of its purport not departed from.
