Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of assisting a user in planning a packing plan for a plurality of parts by using a computer.

[0002]

2. Description of the Related Art Conventionally, in the field of automobiles, which are typical industrial products, in order to efficiently mass-produce products that require many kinds of parts for assembly, various parts are manufactured prior to mass-production. Have been proposed for packing and loading methods during transportation.

As an example of such a proposal, Japanese Patent Laid-Open No.
Japanese Patent Laid-Open No. 1-225916 proposes a technique for allocating a large amount of parts and a small amount of parts efficiently, while allocating the large amount of parts evenly every day, while allocating the small amount of parts based on past shipping patterns.

Further, in Japanese Patent Laid-Open No. 9-002620, based on order information, inventory information, and packing business,
Techniques have been proposed for formulating a packing work plan at predetermined time intervals.

Further, Japanese Unexamined Patent Publication No. 10-187821 discloses a technique of formulating a packing plan in which the packing work is preceded by the lead time so that the packing work and the vanning work are performed in parallel. Proposed.

[0006]

Various methods have been proposed for the packing method and the loading method for transporting various parts as in the prior art described above, but in recent years, necessary members have been provided far away. A so-called knockdown production method is widely used, in which a ship or the like is used to transport to a production base (mainly outside the country) and then the product is produced at the production base.

In the case of adopting such a knockdown production system, conventionally, for example, in order to facilitate management at a local production base, many kinds of component groups necessary for assembling one automobile are packed into one package. In some cases, they are shipped together. In addition, in recent years, in response to the establishment of management systems at local production bases, various parts have been transported in parts or modules for multiple units in order to streamline operations from unpacking to assembly completion. It is becoming possible.

FIG. 11 is a view for explaining the conventional method of transporting various parts in units of a plurality of parts or modules as a unit, and the method according to the present application, here shown on the left side of FIG. The problem in the conventional method will be described.

In the case of transporting various parts in units of a plurality of parts or modules, when an assembled car at a local production base is to be sold locally, for example, the local production is generally performed. Prior to the acceptance of the necessary parts at the base, the local sales department makes an order forecast, and the various parts necessary for completing the number of vehicles based on the order forecast are shipped to the destination (for example, in Japan). Headquarters). In this case, the local sales department generally orders the shipping destination with an amount that takes into consideration some order fluctuations in the number of vehicles based on the forecasted order so that the number of vehicles that are products is not insufficient at the time of sale. Is.

That is, in the conventional system shown in FIG.
The products of F through F are sales forecasts in order of 50, 10
0, 150, ..., 100 were predicted as a total of 700 units, while 10% was considered as the sales fluctuation prediction rate, so each increased by 10%, and the total number of local demand is 5
5, 110, 165, ..., 110, totaling 770 units. With respect to such a total demand, various parts for the number of units actually shipped to the local production base by the shipping destination) are related to the lot allocation at the time of transportation. Further increase in model number, 60, 12
0, 180, ..., 120, totaling 840 units. This quantity is the original order forecast 7 by the local sales department.
The number is 140 units more than 00 units, and the number of units increased due to lot allocation is 70 units.

Therefore, the above-mentioned conventional method of parts transportation is problematic because the local sales department has a large number of completed stock vehicles when the actual orders are below the initial sales forecast.

Further, even in the case of transporting various parts in units of a plurality of parts or modules, in order to further reduce the ratio of the shipping cost of a ship or the like to the product,
Space within each package must be minimized to achieve more efficient transportation.

Therefore, the present invention efficiently packs various parts constituting a plurality of kinds of plural products prior to transportation, and minimizes the possibility that some of the parts become stagnant inventory after being received at the transportation destination. The present invention is intended to provide a packing planning method, a packing planning supporting device, a computer program therefor, and packing instructions.

[0014]

In order to achieve the above object, a packing planning method according to the present invention is characterized by the following configurations.

That is, a first part (common part) group commonly used for a plurality of products of a plurality of types that need to be transported, and the first part used for at least one product of the plurality of types. In order to transport a plurality of products of a plurality of types composed of a second component (individual component) group different from the component group to another place in the state of the first and second component groups before assembly, A method of planning a packing carried out by using a computer prior to the actual packing of the first and second parts groups, which is commonly used for a plurality of products of a plurality of types that need to be transported. Of the parts group, a first step of formulating a packing plan for packing only the first parts group for a plurality of types and / or a plurality of products; and the first plan planning step described above. Multiple types and /
Alternatively, the optimal packaging for only the first component group for a plurality of products and a packaging plan for packaging at least a part of the second component group together in the packaging second
And a process.

In a preferred embodiment, in the second step, the first and second component groups are mixed in the same package.
It is preferable that the packing plan is designed such that the second component group is stored in an empty space area when the first component group is stored in the same package.

Further, for example, prior to the first and second steps, information (outside dimensions, mass, material) about individual components included in the first and second component groups and a plurality of types of packing members. When a storage step of storing information (outer dimensions, material) in the storage device is further included, at least in the second step, the three-dimensional simulation is performed based on the information stored in the storage device, thereby performing the three-dimensional simulation. A packing plan for mixing the first and second component groups in the same packing may be drafted.

Further, for example, the product is an automobile, the first component group is at least one of a suspension, a vehicle body component and a glass component used in the automobile, and the second component group is It is at least any one of an engine used for an automobile, a transmission, and an optional part mounted on the automobile according to an individual instruction.

The same purpose is also achieved by a packing plan planning support device corresponding to the packing plan planning method having the above-mentioned steps, and a packing instruction sheet prepared by such a method and device and presented to the user. Also achieved by.

[0020] Further, the same object is to realize a packaging planning method having the above-mentioned steps, or a program code for realizing a corresponding packaging planning support apparatus by a computer, and a computer reading in which the program code is stored. It is also achieved by possible storage media.

[0021]

According to the present invention described above, various parts constituting a plurality of kinds of plural products are efficiently packed prior to transportation, and some of the parts become stagnant inventory after being received at the destination. It is possible to provide a packing planning method, a packing planning support device, computer programs thereof, and packing instructions that minimize the possibility.

That is, according to the inventions of claim 1, claim 7, and claim 8, the first part group (automobile suspension, car body parts, glass parts, etc.) commonly used for plural kinds of plural products: Only the item 5) is basically packaged separately from the second component group (automobile engine, transmission, optional components equipped according to individual instructions: claim 6). Since at least a part of the second component group is packaged together with the package designed only for the first component group, it is possible to improve the storage efficiency in one package and also improve the transportation efficiency. It's easy.

Further, in this case, the second part can be packaged separately from the first part in terms of management. Therefore, the second part, which is left over in this production, must be newly received from the outside. Instead, it can be transferred to subsequent productions, and it is easy to use up efficiently.
For this reason, it is possible to minimize the possibility that some of the parts will remain in stock after being received at the shipping destination.

According to the second aspect of the invention, the second component group is stored in the empty space area when the first component group is stored in the same package, so that the storage efficiency is maximized. It is possible to reduce the transportation cost of the finished product by ship or the like.

According to the third aspect of the present invention, the first and second component groups can be packed with high precision by interference check by three-dimensional simulation or the like.

Further, according to the invention of claim 4, since the first component group is larger in size than the second component group, when a part of the second component group is packed together with the first component group, For example, since the second component group can be stored in the empty space generated by the storage of the first component group, the storage efficiency in one package can be improved and the transport efficiency can be easily improved.

[0027]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the packaging planning method and the supporting device according to the present invention are applied to a knockdown production system for automobiles (hereinafter abbreviated as "KD system"), which is a typical industrial product. The form will be described in detail with reference to the drawings.

FIG. 1 is a diagram for explaining a production system of a KD type automobile, which is suitable for applying the present invention.

The production system shown in the figure is roughly classified into, for example, a vehicle manufacturer headquarters located in Japan, a local base located overseas, and a transportation means for transporting various parts between them (as an example, a container in the figure). It is composed of a ship 4).

In the present embodiment, the vehicle manufacturer headquarters is
In addition to procuring various parts, of the procured multiple parts of multiple parts, for those that should be transported to the local base,
Develop a packing plan by the procedure described later. Then, the vehicle manufacturer headquarters carries out various parts packed by the packing department in accordance with the planned packing plan, and transports the carried-out individual packages to the local site by using the container ship 4 or the like.

The user terminal 1 is a packing plan planning support device for supporting the planning of a packing plan, which is carried out by the user prior to the actual packing work of various parts to be transported to the local base. For this user terminal 1, a general computer capable of accessing the database 2 which is a storage device and capable of data communication with a local site can be adopted. The procedure is described below based on the acquired information and the sales forecast information acquired from the local base.

The database 2 contains information (outer dimensions, mass, materials, etc.) about various parts required for assembling various automobiles assembled at the local base, and a plurality of pieces used for transporting these parts in predetermined units. Information (outer dimensions, materials) and the like regarding the types of packaging members are stored in advance as illustrated in FIG. 7.

That is, FIG. 7 is a diagram illustrating a data table relating to a plurality of types of parts (common parts and individual parts) required for assembling various automobiles, and this data table is stored in the database 2 in advance. ing.

In the data table, the data record of one type of part includes the part number of the part, the quantity required for assembling one vehicle, the external dimensions, the material, and the weight of a single item (at least Information items such as whether it is light), external dimensions when packed (packed) in a predetermined storage lot (at least one or more), storage lot, unpacking location at the local site, etc. are stored for each individual part. .

Here, the storage lot is a unit of quantity when a plurality of common parts of at least one type are packed by a packing member.

On the other hand, the local site receives the packaging transported from the vehicle manufacturer headquarters in the receiving department, unpacks it, and then hands it over to the assembly department as a group of parts assembled in a predetermined unit. After that, the assembly department at the local base assembles various finished vehicles using the delivered various parts, and the assembled vehicles are sold, for example, in the local market by a sales department (not shown).

The user terminal 3 is a general computer capable of communicating with the vehicle manufacturer headquarters, and the sales forecast information (the forecasted number of orders for various types of vehicles or the number of forecasted number of vehicles is input by the sales department or the like. Information regarding various parts necessary for completion) can be ordered from the user terminal 1 of the vehicle manufacturer headquarters. here,
Similarly to the conventional method described above with reference to FIG. 11, the sales forecast information input by the local base also includes the number of vehicles based on the order forecast in order to prevent a shortage of automobiles, which are products for sale, in the same manner as the conventional method described above with reference to FIG. On the other hand, it is assumed that some order fluctuations are taken into consideration.

In the present embodiment, a plurality of types of automobiles assembled at a local site are provided with a plurality of types of common parts (for example, suspensions, car body parts, glass parts, etc.) that are commonly used by those automobiles, and An individual component different from the common component group, which is used for at least one of a plurality of types of automobiles (for example,
It consists of an engine, a transmission, and a group of optional parts equipped according to individual instructions.

That is, FIG. 10 is a diagram illustrating a classification system of various parts in the present embodiment, and as described above,
Multiple types (models A to F) assembled at the local site
Is a common component group of a plurality of types of automobiles of each model, each component number a to k, and an individual component group (eg, model A
In the case of the car, the parts number 1 to x) are used.

In the following description, when a plurality of common parts are grouped in units of one storage lot, a plurality of common parts of the same type are grouped together (that is, one storage lot is configured for a plurality of vehicle types). Therefore, a case of collecting common components arranged in the horizontal direction in the classification system illustrated in FIG. 10 will be described. However, it is not limited to this way of grouping, and different types of common parts lined up in the vertical direction in the same classification system may be grouped by vehicle type. In this case, a plurality of types used for one vehicle of a certain vehicle type may be used. Since the common parts group is packaged as one unit, it is easy to manage after unpacking at the local production base.

Based on such a classification system, in the present embodiment, as a general rule, the packing of these parts in the local base can be performed separately for the common parts and the individual parts. The feature is that a packing plan is prepared. Hereinafter, a packing plan support process performed by the user terminal 1 that allows the user of the user terminal 1 to easily plan such a packing plan will be described in detail.

2 and 3 are flowcharts showing the packing plan support process performed by the user terminal 1 in the present embodiment, and represent the processing procedure of the software program performed by the CPU (not shown) of the user terminal 1.

In the figure, step S1: the user terminal 1 receives an order input operation by the user. This input operation may be performed by the person in charge of the vehicle manufacturer headquarters in accordance with the order information obtained from the local base, or by the person in charge of the local base remotely using the user terminal 3.

FIG. 4 shows the user terminal 1 for order entry.
FIG. 4 is a diagram showing an example of a screen displayed in FIG. 4, which is a unit of a vehicle type (models A to F) to be assembled at a local site, and is a common part in the display screen shown in FIG. 4A, and is shown in FIG. 4B. Individual parts can be set on the display screen.

That is, the user first uses the display screen of FIG. 4 (a) to target the number of vehicles required for a vehicle of any vehicle type required for the current order, and determines the required number of vehicles. Enter according to lot unit. In the example shown in FIG.
For cars of type A with 0 units / product lot,
"4" product lot is entered. In the present embodiment, the user terminal 1 can refer to the classification system of various parts for each vehicle type shown in FIG. 10 described above by accessing the database 2.
A plurality of types (in this case, part numbers a to k) required to assemble a total of 80 (= 20 × 4) automobiles of type A
This means that the common component group of each component) has been set in the user terminal 1.

Here, the product lot is a minimum production unit (production quantity) when producing (assembling) an automobile of a certain vehicle type, and is preset in the user terminals 1 and 3 for each vehicle type. . Therefore, at the time of producing a certain type of automobile, it is necessary to produce at least a predetermined number of product lots (a predetermined number of one or more).

Further, the user can set the part number and the quantity of the common part ordered as a single item, as necessary, by using the display screen of FIG. 4 (a). Examples of common parts for ordering a single product include, for example, a case where an order is individually placed from a service factory to a local site, or a defective product is mixed in a previously received parts group.

Further, the user can select a group of individual parts (in this case, parts number 1 to x) corresponding to the number of automobiles of the target vehicle type in product lot units set on the display screen of FIG. 4 (a). The quantity of is input to the user terminal 1 using the display screen of FIG. The required quantity of the individual parts group is
The user terminal 1 may set automatically by referring to the quantity of each product lot set on the display screen of FIG. 4A and the classification system of various parts for each vehicle type shown in FIG. .

Step S3: As a part of one automobile, a plurality of the same parts may be used. Therefore, in this step, the quantity required for actual assembly is calculated based on the quantities of the plurality of types of common parts and individual parts set in step S1. The required quantity of individual parts per car is available by reference to the data table shown in FIG. 7 above.

FIG. 5 is a diagram for explaining the required quantity of shared parts and individual parts calculated by the user terminal 1 in response to the order input by the user.

In the example shown in the figure, the necessary number per vehicle is 1 as the number (80 in this case) required for actually assembling the vehicle of the vehicle type A indicated by the product lot number input by the user. The common parts with the part numbers a, b, and c are set to 80 pieces, and the common part with the necessary number of two pieces is 160 pieces. If there is, the quantity of the target parts will be added). Similarly, the number of each individual component is automatically calculated.

Step S4: The user terminal 1 classifies (divides) the required quantity calculated for each common part in step S3 with the storage lot preset for each common part illustrated in FIG. 10 as one unit. To do.

More specifically, the number of stored lots may be classified by type according to (number of stored lots) = (required number of certain common parts) / (predetermined number preset as a stored lot of the common parts).

Step S5: As a result of the classification into the storage lots in step S4, the user terminal 1 generates an excess of common parts, that is, a fraction of common parts which does not satisfy the predetermined quantity preset as the storage lot. It is determined whether or not to proceed, and if the remaining common parts are generated, the process proceeds to step S6, and if not, the process proceeds to step S10.

First, the processing of steps S6 to S9 will be described. It is determined in step S5 that a fractional common component is generated, which means that when a certain type of common component to be targeted is packed in at least one packing member according to a predetermined quantity defined in the storage lot, This means that one of the packages has a state in which the predetermined quantity is not reached, and in this case, there is an unnecessary empty space in the packing member that does not reach the predetermined quantity.

Therefore, in the processing of steps S6 to S9, the processing for optimally packing the remaining (fractional) common parts and the common parts of other types by one packing member is performed.

Step S6: The user terminal 1 refers to the data table shown in FIG. 7 to select the unpacking locations of the remaining common parts and other types of common parts of the same unpacking location. Here, the common parts at the same unpacking location are selected as targets for unpacking after arriving at the local site and after unpacking parts when multiple types of common parts are mixed in one package. This is to facilitate the management of.

In addition, in step S6, when selecting a combination of other types of common parts and the surplus common parts, the surplus common parts are light (heavy) in consideration of damage due to vibration during transportation. ) If the material is
The other types of common components to be selected may also be configured so that a light (heavy) material is automatically selected. In this case, the weight of each common part can be obtained by referring to the data table shown in FIG.

Step S7: When at least one combination of other types of common parts and the remaining common parts is selected in step S6, the user terminal 1 uses one packing member to pack the selected combination. A feasible packing member is selected from a plurality of preset packing members (for example, large, medium, small, etc.).

Step S8, Step S9: The user terminal 1 selects the remaining common parts in the combination of the selected packing member and the remaining common parts housed therein and other types of common parts. In addition to selecting the one having the proper center of gravity balance when stored (step S8), the remaining common parts and other kinds of common parts in the selected combination are in an optimum state without interference (that is, high storage). Items that can be packed with efficiency are selected (step S9).

Here, in step S8, the balance of the center of gravity is verified by the operator and / or the maximum weight of the packaged article by the transfer means (forklift, truck, ship, etc.) and the strength of each packaging member being predetermined. This is to make a realistic choice that does not exceed the limit range.

In addition, in the steps S7 to S9, the packing member is selected, the center of gravity is calculated, and inside the selected packing member, the remaining common parts and other kinds of common parts are in an optimal state without interference. Whether or not it can be stored is determined based on the dimensions of the selected packaging member, the external dimensions of each common component that can be acquired from the data table shown in FIG. The so-called three-dimensional simulation may be used for automatic and highly accurate verification.

FIG. 8 is a diagram illustrating a state in which two types of common parts having the same unpacking location are mixedly mounted on the same packing member. In this case, a plurality of bumpers as the remaining common parts are It is stored in a packaging member of a certain size selected in step S9, and in the empty space generated in the packaging member due to the packaging, a plurality of aero skirts as common components of other types are packaged. Is shown.

Next, step S11 and step S12
The process will be described. Since it was determined in the previous step S5 that a fractional common component will not occur, in this case, the common component is stored in a predetermined packing member preset in the data table shown in FIG. 7 in storage lot units. Will be done. However, even in such a case, a certain amount of empty space may remain depending on the shapes of the packing member and the common parts housed therein.

Therefore, steps S11 and S1
In the process of 2, the vacant space around or inside a plurality of common components of a certain type stored in a predetermined packing member in units of storage lots is targeted, and individual components that can be stored in the vacant space are targeted. , In addition to the various common parts described above in this packing plan, select from various individual parts that need to be transported to the local site.

Step S11: The user terminal 1 refers to the data table shown in FIG. 7 to refer to the same unpacking place as the unpacking place of various common parts that need to be transported to the local base in this packing plan. The individual parts of the above are selected from various individual parts that need to be transported together with the common parts. Here, the common parts and the individual parts that are in the same unpacking location are selected as targets for unpacking and unpacking after the arrival at the local site when the common parts and the individual parts are mixed in one package. This is because it is easy to manage the parts later.

In step S11, when selecting a combination of a certain type of common component and a certain type of individual component, considering the damage due to vibration during transportation, etc., the size of the common component is It is preferable that the small-sized individual parts are automatically selected. In this case, the weight of each common part and individual part can be obtained by referring to the data table shown in FIG. By performing such storage, the storage efficiency in one package can be improved, and the transportation efficiency can be easily improved.

Step S12: When at least one combination of common parts and individual parts having the same unpacking location is selected in step S11, the user terminal 1 separates the common parts and the individual parts from the selected combination. Select a product that can be packed in an optimal state (that is, high storage efficiency) without interfering with other parts. Whether or not it can be stored in an optimal state without interference is packed (packed) in units of individual lots or storage lots of common parts that can be acquired from the data table shown in FIG.
The so-called 3 based on the external dimensions when the storage lot is stored, the dimensions of a predetermined storage member that is to store the storage lot, the external dimensions when the individual parts are individually packaged or packaged in the storage lot.
It is sufficient to verify automatically and with high accuracy by using the dimensional simulation.

FIG. 9 is a view exemplifying a state in which a certain type of common component and a certain type of individual component having the same unpacking location are mixedly mounted on a predetermined packaging member for storing the common component. In this case, , A plurality of door panels as common parts are accommodated in a predetermined packaging member for accommodating the door panels, and the accommodation efficiency in one package is improved in an empty space generated in the opening portion of the door panel due to the accommodation. In order
It shows a state in which a plurality of roof rails as individual parts are stored in a packaged state. By carrying out such storage, the storage efficiency can be maximized and the transportation cost of the finished product by a ship or the like can be reduced.

Step S13, Step S14: By the processing in each of the steps described above, inside the user terminal 1, various common parts and individual parts that need to be transported to the local base in the packing plan are stored in the storage members. The mode has been decided. Therefore, in order to realize the determined storage mode in the actual packing operation, the user terminal 1 concretely stores various common parts and / or individual parts that need to be transported into individual storage members. A packing plan is organized by calculating the allocation (step S1
3), the composition result is displayed on the display of the user terminal 1 (step S14).

FIG. 6 is a diagram showing an example of a packing plan display screen presented to the user by the packing plan support apparatus according to the present embodiment. Fig. 7 illustrates a manner of storing common components and individual components in individual storage members.

That is, in the packing plan illustrated in FIG.
For example, the part number a, which is a common part, has a total quantity of 80 pieces to be transported and one storage lot has 20 pieces.
The 80 common parts having the part number a are transported by the four packing members having the packing numbers A1 to A4.
In this case, the four packing members are the data shown in FIG.
The same size preset in the table is adopted, and a predetermined number of 20 parts with the part number a are stored in any of the packing members with high storage efficiency.

Since the total number of parts to be transported, which is part number e, is 84, and one storage lot is 20, the 84 common parts with part number e are It means that the product is transported by five packing members of packing numbers E1 to E5. However, in this case, as the four packing members of the packing numbers E1 to E4, those of the same size preset in the data table shown in FIG. Is stored with high storage efficiency.

With respect to the above four packing members of the packing numbers E1 to E4, the packing number E5 needs to store 4 fractions by dividing the packing lot unit.
In order to make the user recognize that, the display mode is “E5 (4)”. Then, in this case, the common parts of 20 parts in one storage lot should be mixed together in the storage member of the packaging number E5 as the optimum combination selected in the processing of steps S6 to S9. In order to make the user aware that, in the packing plan illustrated in FIG. 6, in the packing number column of the common part of the part number c, seven packings of packing numbers C1 to C7 in which packing members of a predetermined amount and a predetermined size are selected In addition to the parts,
The packaging member having the display form "E5 (20)" is displayed.

Then, the total number of parts to be transported, which is the part number n, which is an individual part, is three, and the packing number column in the packing plan illustrated in FIG. 6 has a display mode of "B1 <3>". Is displayed as, and as the optimum combination selected by the processing of step S11 and step S12 described above, together with the common parts of the part number b of 1 storage lot 20 packed in the packing member of the packing number B1, For example, as illustrated in FIG. 9, it indicates that the individual components are to be mixedly mounted in the empty space formed by the common component group.

Step S15 to Step S17: The user terminal 1 has past (for example, past 1) about the common parts of each type which are the packing targets in the packing plan illustrated in FIG.
The transport status of about 0 times is referred to (step S15), and based on the referred result, it is determined whether the storage quantity of one storage lot in the packing plan calculated in step S13 should be changed (step S16), and it is necessary. In that case, a warning (suggestion) is given to the user (step S17).

That is, steps S16 to S17
Then, for example, if the transportation record of a plurality of common parts to the local site in units of storage lots is 0, and only the single item order is being transported, then 1 storage lot will be calculated from the current setting value. It is suggested to the user to adopt a small value.

In addition, the transportation record of a plurality of common parts to the local site in units of storage lots is +3 lots more than the average value of the past 6 to 10 times before the past 5 times. If it is increased above, the current set value per storage lot is changed to a larger value which is a common divisor of 60 (for example, the current set value of 20 per storage lot is changed to 30). ) Is suggested to the user.

Here, when a plurality of common parts are stored in one packing member as one storage lot, a common divisor of 60 is preset in this embodiment, and the proposal in step S17 is also 60. Is selected, and in a more preferred embodiment, 3 of the 60 common divisors
A value of 0, 20, 12, or 6 is preferable. The reason is that in general, as a transportation means used to transport various parts to overseas bases, a vessel with a vertically long body (container ship) is generally used, and the shape of the container to be loaded is also vertically long. However, when a packing member in which a plurality of common parts and the like are packaged (packed) is housed inside a ship or container having such a shape, a plurality of packages packed in each packing member as one storage lot are stored. As for the packing style (arrangement) of common parts, the vertically long shape is more efficient in storage. Therefore, in the present embodiment, the four values (30, 20, 12, 6) among the common divisors of 60 are adopted for the arrangement of a single tier except for the case of stacking in a plurality of tiers in the vertical direction. Since the arrangements of 5 × 6, 4 × 5, 3 × 4, and 2 × 3 can be adopted in order, a vertically long arrangement can be realized in any direction on the two-dimensional plane, which enables the packing work. It is possible to realize a storage mode in which the property is excellent, the load does not easily collapse, and the storage efficiency is excellent.

If the basic number of common parts (including the case of ordering a single product) of the average value in the storage lot unit from the last five times to the one before is divisible by the common divisor of 60, the divisible value Of which, from the last five times, 1
It is suggested to the user that the value can be set to a value larger than the previous average value. Here, the basic number is a value when it can be multiplied by x.

As described above, according to the above-described present embodiment, for example, by utilizing the three-dimensional simulation technique, a common component group commonly used for a plurality of products of a plurality of types (an automobile suspension, a vehicle body component, a glass component). As a general rule, a packaging plan is devised in which only the individual parts group (automobile engine, transmission, optional parts equipped according to individual instructions) are packaged independently,
The common parts group can be efficiently packed, and the transportation efficiency can be easily improved.

FIG. 11 is a view for explaining the conventional method of transporting various parts in units of a plurality of parts or modules and the method according to the present invention, and the conventional method will be described first. As you can see, while the total number of each model to be assembled at this time was 700 units,
Finally, in consideration of the sales fluctuation prediction rate, various parts for 840 units were procured.

On the other hand, in the method according to the present application (this embodiment), the common component and the individual component can be considered separately under the same procurement conditions. Therefore, the individual component is different from the conventional method. Similarly, 840 units are required, but for multiple types of common parts common to each car model,
It is enough to procure 700 units based on the original order forecast.
Compared with the conventional method, it is possible to reduce the procurement of 140 types of common parts of a plurality of types.

That is, in this embodiment, the individual parts are
In principle, it can be packed separately from the common parts. As a result, the individual parts that were left over from the previous production at the local site can be transferred to the next and subsequent productions without being newly accepted from the vehicle manufacturer headquarters, and can be used up efficiently and easily. It is possible to minimize the possibility that some of the parts will remain in stock after they are received at.

Therefore, according to the present embodiment described above, it is possible to easily plan a packing plan for efficiently packing various parts constituting a plurality of kinds of plural products prior to transportation, which is convenient for the user. high.

The present invention described in each of the above-described embodiments is provided with a computer program capable of realizing the functions of the flowcharts referred to in the description, with respect to the user terminal 1 as the above-mentioned packing planning support apparatus. It is achieved by supplying it to the CPU of the device and then executing it. Further, the computer program supplied into the device may be stored in a readable / writable memory or a storage device such as a hard disk device.

Further, in the above case, the method of supplying the computer program to each of the devices may be a method of installing the computer program through various recording media such as a floppy (registered trademark) disk or the Internet. A general procedure can be adopted at present, such as a method of downloading from the outside via a communication line. In such a case, the present invention provides
It is composed of a program code or a storage medium.
