The logistics device 6 is for transporting the thin plate coil stored in the product warehouse 11 to the inside of the ship 17 and includes the above-described conveying device and the like in addition to the crane crane 15.

Fig. 12 is a flowchart showing the procedure of the transportation availability planning processing executed by the transportation availability instruction calculator 3 in the first embodiment. The transportation allowance instruction calculator 3 carries out the transportability compulsory plan creating method by carrying out the transportation compulsory planning preparation processing in accordance with the processing procedure of Fig. The processing described here can be realized by recording a program for realizing the transportability compulsory plan creation processing, for example, in the recording device of the transportability instruction calculator 3, and reading and executing the program.

Although the transportation compulsory plan prepared in this transportation compulsory planning preparation processing is prepared for each shipment plan, it is also possible to determine which transportation plan is to be prepared for which shipment plan, for example, an operation of designating the shipment plan by an operator in advance . In the transportation availability planning process, the transportation ability instruction calculator 3 first executes the shipping data input process as data input means, and transmits the product information file 41, the shipping schedule file 42, (Step S1; data input step). [0054] The data input step is a step of inputting the data to be transmitted to the vehicle.

More specifically, a record in which the plan ID is set is read from the shipment planning file 42 based on the plan ID of the shipment plan designated as described above. Then, a record in which the product ID is set is read from the product information file 41, based on the product ID (i.e., the product ID of the coil to be shipped) set in all the records read from the shipping plan file 42. [ Further, a record in which the warehouse ID is set is read from the warehouse information file 43, based on the warehouse ID set in any record read from the product information file 41. [

Then, the transportability instruction instruction calculator 3 carries out the can compulsory plan processing as the can compulsory compulsory planning means and creates a compulsory compulsory plan by referring to the operation constraint file 44 and the dock information file 45 (step S3; Data Entry Process / Dock Validation Process). More specifically, the transportability instruction calculator 3 refers to the work constraint file 44 and the dock information file 45, and based on the plan supply data input in step S1, ) To create a line, and allocates a proper order to the coil to be shipped for each created line.

First, the order of creating the lines will be described. However, before this, description will be given of how the coil to be shipped to the ship 17 is to be shipped. Fig. 13 is a view showing the proper condition of the coil C1 to be shipped to the ship 17, schematically showing the inside of the ship 17 brought into contact with the seawall 17. 13, the ship 17 has a substantially rectangular parallelopiped berth 171 which is elongated in the longitudinal direction of the hull and has an open upper surface. The coil C1 to be delivered has a width of the berth 171 And are loaded in the hold 171. 13 shows the coil C1 to be shipped arranged in two rows. However, in the actual hold 171, there are a plurality of shipment target coils arranged so as to fill the space in the hold 171, do. The more the coil is arranged without the gap, the higher the coil loading rate in the holder 171 is.

At this time, in the case where the coil to be shipped, which is a cylindrical thin plate coil, is placed in the rectangular holder 171 as in the first embodiment, the coil to be shipped is treated as a unit of lot called a line. Specifically, after a line (a lot lot) is formed by a plurality of shipment target coils including a so-called key coil, the shipment target coils constituting the line are arranged in a line in the first stage in the loading window 171, And the key coil is applied to the second stage. For example, the coil group of the coil C11 to be shipped including the second-stage key coil C13 surrounded by a broken line in Fig. 13 corresponds to one line L. Here, the key coil fulfills the role of the wedge, which is fitted above the gap between the first-stage coils installed in the first stage. The coil to be shipped to be the key coil may be properly selected, but the difference between the gap immediately below and the outer diameter of the key coil needs to fall within a predetermined allowable range. 13 shows a case where one key coil is applied to the second stage. However, in some cases, a plurality of shipment target coils including a key coil are applied to the second stage (two stages). For example, a line may be formed on the assumption that the odd coil group to be described later is applied to the second stage in addition to the second stage, (see Embodiment 2). In this case, the lines are sequentially arranged from the first-stage coil to be shipped, and then the second-stage coil to be shipped is laid out.

It is preferable that the widths of the coils to be shipped constituting the line coincide with each other as much as possible. This is because, when the coils to be shipped with similar widths are arranged, the gap between the adjacent lines generated by the concave and convex in the width direction of the collet 171 can be minimized, and the coil loading rate in the collet 171 can be improved. These lines are created by collecting the coil to be shipped having similar property values in one coil group based on the property set in the coil to be shipped. As described above, the shipment coil having a high degree of similarity of attribute values has not only its width but also its outer diameter and weight. Therefore, if the lines are formed by collecting the coils of the same or similar properties, it is possible to minimize the gap between the adjacent lines in the above-mentioned berth 171, and to contribute to the balance of the vessel 17 have.

As an actual process, first, the coil to be shipped is classified into product warehouses 11 to be stored before shipment. Then, the stored product warehouse 11 creates a line for each coil to be shipped of the same warehouse classification. That is, as a starting point of the consolidation, a coil to be shipped with the highest delivery date among the shipment target coils of the same warehouse classification is selected. If the selected coil is the same as the selected coil, the coil is searched among the coils to be shipped in the same warehouse classification. At this time, since the number of coils that can be arranged in one row in the width direction of the hold 171 is limited by the width of the hold 171, the sum of the outer diameters of the coil to be delivered, 171). ≪ / RTI > For the key coil, the group of coils is sorted in ascending order of weight, and whether or not two-stage winding is possible in order from the light side is determined while investigating the relationship with the first coil. That is, if there is a gap between the first-stage coil and the outer diameter of which the difference from the outer diameter is within the predetermined allowable range, the coil to be shipped is set as a key coil and placed above the gap between the corresponding first- The key coil is added to the end of the corresponding line.

Thereafter, the coil to be shipped having the origin of the aggregation is selected from the remaining coils to be shipped in the same warehouse classification, and the lines are sequentially configured in the same manner. For the group of the remaining odd-numbered coils that do not constitute the final line, it is checked from the relationship with the first-stage coil that the two-staged line is possible on the completed line. Whether or not the two stages are possible is determined by whether or not two task constraints relating to the work process in the " dock " when performing the " two-stage " Specifically, the difference between the weight of the coil to be shipped in the group of the superior coil and the average weight of the coil to be shipped to the both sides of the gap immediately beneath the coil is within a predetermined allowable range, and the outer diameter of the coil to be shipped, It is judged that the two-stage capability is possible if the difference from the average outer diameter of the coil to be shipped which is applied to both sides of the immediately lower gap is within the predetermined allowable range. In this way, the coil to be shipped in the group of the superior coil is made into the second-stage coil which is provided between the first-stage coil which can be two-stage as described above of the line in which the constitution is completed, and is added to the end of the corresponding line.

As described above, if all of the to-be-shipped coils are grouped into the coil group for each warehouse classification, and the line is created, the proper order of the to-be-shipped coil is planned. 14 is a diagram showing an example of a line. The correct order is assigned by consecutively numbering the coil to be shipped for each line created. For example, in the example shown in Fig. 14, when the order of shipment from the coil C21 at the head of the line 1 is successively energized and the coil C23 at the end of the line 1 is consecutively shipped, The order is the coil C25 at the head of the line 2 to be shipped. Thereafter, the order of application is repeated for all the shipment target coils for each line in the same manner.

In addition, the order of arranging the lines when putting the coil to be shipped in the hold 171 in practice is the same as the order of the lines 1, 2, 3, 4, 5, 6, ... It is necessary to determine the center of gravity in the hold 171 so as not to deviate. This is to ensure the balance of the vessel 17 in the dropping (right) or in the unloading. For example, each line is rearranged in order from the line having the largest average individual weight of the coil group. Then, each line is alternately arranged on the forward (bow) side and the stern side (stern) side of the porthole 171 in the alternate order, and a line having a small average unit weight is arranged in the vicinity of the center of the porthole 171 . Further, it is also possible to arrange the order of lines after determining the order of arranging lines in this manner.

12, the transportability instruction calculator 3 refers to the lot availability sequential condition table 463 of the pallet restricting file 46 as the setting means, The lot sequential condition as the loading condition is initially set (step S5; setting step). Details of the lot fitting sequential condition will be described later, but in step S5, an arbitrary value between the minimum value and the maximum value of the lot fitting sequential condition shown in Fig. 9 is generated, for example, at random, . The lot specific sequential conditions to be initially set here may be appropriately changed in step S13 to be described later. However, when lot specific sequential conditions are randomly generated, Quot; is checked. The setting of the value between the minimum value and the maximum value of the lottermin sequential condition is not limited to the case where the value is generated randomly. For example, the initial value may be set as the minimum value, So as to be changed.

12, the transferability instruction calculator 3 executes the transfer pallet loading plan processing as the pallet loading plan unit, refers to the operation constraint file 44 and the pallet constraint file 46, The pallet loading plan is created (step S7; transfer pallet loading planning process). Specifically, the transportation allowance instruction calculator 3 refers to the work constraint file 44, the pallet information 461, and the lot allowance sequential condition table 463, and based on the plan supply data input in step S1 A stacking plan (conveying pallet stacking plan) is created in the conveying pallet by stacking the coil to be shipped in the conveying lot and arranging the conveying lot in the conveying pallet in the conveying pallet in accordance with the lot loading order.

First, the principle of the transfer pallet loading plan processing will be described. As described above, the conveyance pallet is used for conveying the coil to be shipped from the product warehouse 11 to the seawall. However, in the conveyance pallet loading planning process, the problem of placement of the coil to be shipped to the conveyance pallet is solved, Create a plan. Fig. 15A is a diagram showing a configuration example of the transport pallet 7; Fig. The transport pallet 7 is constituted by arranging a plurality of skids in which at least one coil to be shipped is stationary in one column or a plurality of columns. For example, the conveying pallet 7 in Fig. 15A is constituted by arranging seven skids 71 in two rows by seven, and corresponds to the conveying pallet of the kind "PA" shown in Fig.

15B is a view showing an example of the loading state of the coil C3 to be shipped to the carrying pellet 7 shown in Fig. 15A. In Fig. 15B, all the skids 71 are supplied with the coil C3 to be shipped. Are stacked one by one. However, as shown in FIG. 15B, it is not always possible to load the coil to be shipped one by one to all the skids 71, and the width of the coil to be shipped, whose width or outer diameter exceeds the maximum allowable size of the transport pallet 7, A plurality of skids 71 are occupied on the transport pallet 7. 15B, the longitudinal direction of the conveying pallet 7 is referred to as " pallet row direction ", and the short side of the conveying pallet 7 along the width direction of the coil C3 to be shipped on the conveying pallet 7 Direction is referred to as " pallet width direction ". For example, as shown in Fig. 8, the maximum size of the conveying pallet 7 that can be continuously arranged with respect to the width is 1200 (mm), and the coil to be shipped having a width exceeding 1200 (mm) Two consecutive rows can not be stacked in two rows. As described above, it is necessary to load the wide-width delivery coil in one row in order to occupy the skid 71 adjacent on the transport pallet 7 in the width direction of the pallet. On the other hand, the maximum size of the conveying pallet 7 that can be continuously arranged with respect to the outer diameter is 1250 (mm), and the coil to be shipped having an outer diameter exceeding 1250 (mm) has two skids 71 continuous in the pallet row direction They can not be stacked one by one and can not be stacked. Thus, the coil to be shipped with a large outer diameter occupies the skid 71 adjacent to the carrying pallet 7 in the pallet row direction.

That is, the continuous arrangement in the pallet width direction and the continuous arrangement in the pallet row direction of the coil to be shipped are limited by the width and the outer diameter of the coil to be shipped, so that the arrangement problem of the coil to be shipped to the transfer pallet 7 Is a complicated two-dimensional arrangement problem due to the possibility of these continuous arrangements. Therefore, in order to simplify the arrangement problem and to make the calculation easier, in the case where the continuous arrangement in the pallet width direction is possible, the two delivery target coils are collected to form one transport lot, while the two delivery lots are continuously arranged in the pallet width direction If it can not be done, each is treated as one transport lot and the batch problem is converted to one dimension. That is, if the coil to be shipped is concentrated in such a conveying lot, the above-mentioned arrangement problem is regarded as a process of arranging and sorting the conveying lots in a plurality of conveying pallets in a line in accordance with the correct order for each conveying lot can do.

With the concentration of this transport lot, the minimum unit is defined as one unit. Specifically, in the conveying pallet 7 of Fig. 15A, the smallest conveying lot occupies two upper and lower skids 71 (for example, a range A3 surrounded by a one-dot chain line) adjacent in the pallet width direction. The minimum unit of this transport lot is defined as one unit. In this case, the conveying pallet 7 can load a conveying lot for a maximum of 7 units.

Fig. 16 is a view showing an aggregation situation in which the line shown in Fig. 14 is concentrated on the conveying lot. Since the effective part of the coil to be shipped into the hold 171 is carried out in the proper sequence in succession for each line, the concentration of the conveying lot is also performed for each line.

First, focus on line 1. Here, it is assumed that the width and outer diameter of the coil to be shipped constituting the line 1 are all the maximum dimensions that can be continuously arranged. In this case, since each of the coil to be shipped can be arranged continuously in the pallet width direction, two pieces are collectively grouped in order from the beginning of the line to form a conveying lot L41. On the other hand, since it is also possible to arrange in the pallet row direction, the unit number of each transporting lot L41 is set to one unit. However, when the number of coils constituting the line is an odd number, the number of units of the transporting lot L411 constituted by one remaining shipping coil is set to 0.5 units.

Next, attention is focused on line 2. The coil to be shipped constituting the line 2 is assumed to have a width exceeding the maximum allowable length of all the continuous arrangements, and all of the outer diameters shall be equal to or smaller than the maximum allowable continuous dimension. In this case, since each of the coil to be shipped can not be continuously arranged in the pallet width direction, each of the to-be-shipped coils is used as a transport lot L42. On the other hand, since the continuous arrangement in the pallet row direction is possible, the number of units of each transporting lot L42 is set to one unit.

Next, attention is focused on line 3. With respect to line 3, it is assumed that the width of the coil to be shipped is less than or equal to the maximum dimension that can be continuously arranged, and that the outer diameter exceeds the maximum dimension that can be continuously arranged. In this case, since each of the coil to be shipped can be arranged continuously in the pallet width direction, two pieces are collectively grouped in order from the beginning of the line to form a conveying lot L43. On the other hand, it is not possible to arrange them continuously in the pallet row direction. In this case, the number of units of the transporting lot L43 is set to be larger than the number of units of the transporting lot L43, which is determined from the relationship between the maximum size capable of being continuously arranged with respect to the outer diameter of the transporting pallet 7 and the outer diameter of the transporting lot L43 Setting. Here, for example, the unit number of each transporting lot L43 is set to 2.5 units. For example, when the coils having a large outer diameter can not be arranged continuously, the number of units is set to three units, and when two coils having a large outer diameter are arranged continuously, the unit The number may be set to 2.5 units. Further, when three or more coils having a large outer diameter are continuously arranged, the number of units may be set to 2.5 units at both ends, and to 2 units at both ends.

In this manner, all the shipment target coils constituting all the lines are concentrated on the conveying lot. For example, the coils to be shipped constituting the line 4 are concentrated in the transport lot L44 each having 1.5 units, and the coils to be shipped constituting the line 5 are concentrated in the transport lot L45 each having 2.5 units .

However, there are work constraints to be considered in solving the problem of placement of the coil to be shipped to the transfer pallet. That is, as shown in Fig. 6, the maximum number of pellets placed at the pellet mounting place on the quay wall is fixed at four, and the maximum number of the pellet mounting positions is four at a time. For this reason, in the work process in the " quay wall ", it is necessary to replace the unloaded conveying pallet with the conveying pallet before the unloading, and to provide a coil to be unloaded on the conveying pallet. In addition, under these operating constraints, the coil to be shipped must be loaded in the proper order.

On the other hand, if the number of conveying pellets to be used can be minimized by efficiently stacking the coil to be shipped on the conveying pallet with as few empty skids as possible, the logistics cost can be reduced. Therefore, it is preferable to appropriately allow the loading of the coil to be shipped having a different ordering to the same carrying pallet. However, in the case of loading a coil to be shipped with a stacking order on one transport pallet, the transport pallet stays in the pallet placement place until the shipment of the coil in the proper order in the proper order is completed . Therefore, if the difference in the order is excessively allowed, the pallet placement place is filled with the transfer pellet which is not vacated, and the new transfer pallet can not be placed in the pallet placement place, Lt; / RTI >

Therefore, in the carrying pallet loading planning process, lot loading order is assigned to each of the conveying lots concentrated as described above, and the value of the lot loading order of the conveying lot that can be placed on the same carrying pallet is appropriately set By solving batch problems while changing, you can create a feasible transfer pallet load plan that does not violate job constraints while controlling logistics costs.

Figs. 17 and 18 are diagrams for explaining the order of arranging the conveying lots in the conveying pallet, and show the manner in which the conveying lots for each line shown in Fig. 16 are arranged in the order conveying pallets in accordance with the lot fitting order. Here, the lot loading order is set by sequentially stacking the concentrated transport lots. In the drawings of Figs. 16 to 18, the grouting order is attached to each transport lot.

In the preparation of the conveyance pallet loading plan, first, the pallet placement place of the seam is divided into four, and each of them is defined as the pallet placement place (1 to 4). Four transfer pallets (1-4) (1 to 4). First, the first pallet placing place 1 is set as the target pallet placing place, and the conveying lot L41 of the line 1 shown in Fig. 16 is arranged in the order of lot application to the carrying pallet 1. [ As described above, the number of units of the transporting lot L41 in the line 1 is one unit. Accordingly, at the time when the seven transport lots L41 constituting the line 1 are arranged on the transport pallet 1, the transport pallet 1 is full of seven units (the number of remaining units = 0) . A new conveying pallet 5 is prepared and assigned to the pallet placing place 1 and the object is moved to the pallet placing place 2 and moved to the arrangement of the conveying lot in the following lot loading order.

That is, the pallet placement place 2 is set as the target pallet placement place, and the conveying lot L42 is sequentially disposed on the conveying pallet 2 from the top of the line 2 in the order of the lot fitting order. The number of units of the transporting lot L42 in the line 2 is one unit, and the number of units is seven times as many as seven at the beginning. Therefore, after a new transfer pallet 6 is assigned to the pallet placement place 2, the object is transferred to the pallet placement place 3. Then, the remaining four transport lots L42 of the line 2 are sequentially arranged in the transport pallet 3. As a result, four conveying lots L42 are arranged in the conveying pallet 3, and the number of units remaining in the conveying pallet 3 is three units.

Next, the transport lot L43 of the line 3 is arranged. The number of units of the transporting lot L43 of the line 3 is 2.5 units and does not exceed 3 units of the remaining number of units of the transporting pallet 3. Therefore, the transporting lot L43 can be disposed in the transporting pallet 3 in a formal manner, but is not disposed in the transporting pallet 3 in the transporting pallet 4 in Fig. This is because the coil to be shipped of the transporting lot L42 which has been disposed immediately before the transport pallet 3 is different from the product warehouse 11 to be stored in the coil to be shipped of the transporting lot L43 of the line 3 to be. If the product warehouses 11 to be stored are different and are mounted on the same transport pallet, it is necessary to transport the transport pallets between the product warehouses 11, and a transportation cost is incurred. For this reason, in the actual proper work, the operation of loading the items stored in the different product warehouses 11 on the same transport pallet is not performed. Along with this, when creating the transfer pallet loading plan, the transfer pallet to be arranged for each product warehouse 11 is divided, and the object is transferred to the pallet loading place 4. At this time, since the conveying pallet 3 is not ten thousand times, the conveying pallet 3 is allocated to the pallet placing place 3.

Then, the conveying lot L43 of the line 3 is arranged with respect to the conveying pallet 4 of the pallet placing place 4. Since the number of units of the transporting lot L43 is 2.5 units, only two transport lots L43 can be arranged in the transporting pallet 4. However, since the conveying pallet 4 is not full-size even if two conveying pockets 4 are arranged, the two conveying lots L43 in which the lot loading order is ahead are arranged, and the conveying pallet 4 is assigned to the pallet placing place 4 We move object to next pallet placement place. Also, as in this case, when the current target pallet placement place is the pallet placement place 4, the next target pallet placement place is referred to as the pallet placement place (1). Thereafter, two conveying lots L43 in the following lot loading order of the line 3 are arranged in the conveying pallet 5 of the pallet placing place 1 in the same manner, The two transport lots L43 of the lot loading order of the next next to the line 3 are arranged in the transport line L43 of the line 3 and the arrangement of the transport lots L43 of the line 3 is completed.

Next, the conveying lot L44 of the line 4 is arranged. Since the number of units of the conveying lot L44 in the line 4 is 1.5 units, first, the conveying lot L441 with the lot fitting order is disposed in the conveying pallet 6 in the pallet placing place 2 as the target pallet placing place . At this point of time, the number of units remaining in the transfer pallet 6 is 0.5 units, and the transfer lot L443 after the lot loading order can not be arranged. Therefore, the pallet loading place 3, . At this time, the number of units remaining in the transfer pallet 3 in the pallet placement place 3 is 3 units, and the transfer lot L443 can be arranged in a formal manner. However, in this transfer pallet 3, Four transfer lots L42 are disposed. In such a case, the above-mentioned lotwise sequential conditions are considered. In the illustrated example, the lot loading order of the final transporting lot L42 is "18", and the lot loading order of the transporting lot L443 is "26", so that the lot loading order is " 8 ". Therefore, when the lot loading sequential condition is equal to or larger than "8", that is, when the arrangement of the transport lots in which the lot loading order is eight is permitted, the transport lot L443 is arranged in the transport pallet 3. Here, it is assumed that " 10 " is set as lot sequential condition, and the conveying lot L443 is arranged in the conveying pallet 3.

Next, the transporting lot L45 of the line 5 is arranged, but the unit number of the transporting lot L45 of the line 5 is 2.5 units, while the remaining unit number of the transporting pallet 3 is 1.5, The lot L45 can not be placed in the transfer pallet 3. In this case, it is checked in turn whether or not the delivery lot L45 can be arranged in any one of the other pallet placement places 1, 2, and 4. In the illustrated example, since the number of units remaining in the conveying pallets 5, 6, 4 is less than the unit number of the conveying lot L45 in any pallet placement place 1, 2, 4, does not exist. As a result, in order to arrange the transporting lot L45, it is necessary to newly prepare another transporting pallet 7 as shown only in Fig. In the conveyance compulsory planning of the conveyance pallet loading plan, it is planned to put the conveying pallets in a number exceeding the maximum number of pellets in the pallet placing place of the quay wall into the hold 171 of the shipment target coil, It violates the conditions.

Here, with reference to FIG. 18, it is assumed that the lot sequential condition is stricter (smaller) than the above case and the lot sequential order " 8 " For example, the lot sequential condition is set to " 5 ". As described above, when the lot fitting sequential condition is smaller than "8", the transport lot L443 with lot loading order "26" does not satisfy the lot loading condition. In this case, as shown in Fig. 18, the transporting lot L443 is not disposed in the transporting pallet 3, but the transporting pallet 7 is newly allocated to the pallet placement place 3 and arranged there. As a result, in Fig. 17, it is possible to arrange the next transporting lot L45 after the next line 5 which can not be arranged at any pallet placement place, and thus can solve the violation of the working constraint condition.

However, if the allowable lot loading sequence is made smaller, the pallet loading rate is lowered, and the number of conveying pallets (the number of used pallets) used increases accordingly. For example, in FIG. 17, up to the transporting lot L443 can be arranged in six transporting pallets 1 to 6, while in FIG. 18, the transporting lot L443 is arranged in the seventh transporting pallet 7, . 17, when the pallet placement place 4 at the time of placing the transporting lot L45 in the correct order " 27 " is considered, the transporting lot L45 is moved to the transporting pallet 4 , The appropriate sequence with the batch L 43 is "7", and the lot sequential condition "10" in FIG. 17 is satisfied. On the other hand, the proper sequence "7" of the conveying lot L45 and the conveying lot L43 arranged in the conveying pallet 4 does not satisfy the lot applying sequential condition "5" in Fig. Therefore, in the case of Fig. 18, it is not possible to arrange a new conveying lot in the conveying pallet 4 at this time. At the time of placing the transporting lot L45 of the next correct procedure " 28 " in the transporting pallet 7, the transporting pallet 5 of the pallet placing place 1 does not satisfy the lot applying sequential condition " 5 & It becomes impossible to arrange a new transporting lot to the transporting pallet 5 at this point. In this manner, decreasing the lot loading sequence increases the number of used pallets and directly affects the increase of the logistics cost. This logistics cost is considered in the later-described logistics cost calculation processing (see step S9 in Fig. 12). As described above, if the lot loading order can be placed in the transport pallet up to the last transport lot, the transport pallet loading plan can be created, and the number of pallets used in the transport pallet loading plan is determined.

Next, the procedure of the loading plan processing of the transfer pallet 6 will be described with reference to Fig. In this carrying pallet 6 stacking planning process, the conveying enabling instruction calculator 3 first collects the to-be-shipped coil on a conveying lot basis for each line created in the shelf correcting plan process of the previous stage (step S701). Then, the transportation allowance instruction calculator 3 assigns the lot fitting order to each of the concentrated transportation lots in succession for each line (step S703).

Then, the transportability instruction calculator 3 initializes the remaining number of units by allocating transport pellets one by one to the four pallet placement places on the sidewall (step S705), and at the same time, , And the target pallet placement place is set as the pallet placement place 1 (step S707). The initialization of the remaining number of units is performed by setting the maximum number of units of the transfer lot that can be loaded into the transfer pallet to the remaining number of units.

Then, the transportability instruction instruction calculator 3 determines whether or not the lot fitting sequence condition is satisfied based on the lot fitting order of the lot of the target lot (step S709). In the case where the conveyance pallet 6 loading plan process is executed for the first time, the lot loading sequential conditions are initially set in step S5 of FIG. 12 in the preceding stage. However, in step S709 of FIG. 19, It is determined whether or not the difference from the lot loading order of the conveying lot that has been placed in the conveying pallet at the pallet placing place satisfies the above-described initial lot set sequential condition. In the case where the transport pallet loading planning process is executed after the second time, as a result of judging that a work constraint violation is considered in step S737 in the subsequent stage, or that improvement is required for the logistics cost calculated in step S9 in Fig. 12, In the subsequent step S13, the lot fitting sequence condition is changed. In this case, in step S709 of Fig. 19, it is judged whether or not the above-mentioned lot fitting sequence condition is satisfied.

If the lot fitting sequence condition is satisfied (step S709: Yes), the transportation allowance instruction calculator 3 determines whether or not the arrangement of the object lot is possible (step S711). When the number of units of the target lot is less than the number of units remaining in the transfer pallet of the target pallet placement place or when the product warehouse 11 to be stored is different from the transfer lot in which the transfer lot is placed in the transfer pallet, It is determined that it is impossible. In addition, there is also a restriction that the carrying pallet can not be loaded with a weight exceeding the maximum carrying weight shown in Fig. 8, so that the sum of the weights of the carrying lot and the target lot, , It is determined that placement is impossible.

If the target lot can be arranged (step S711: Yes), the transportation allowance instruction calculator 3 places the target lot on the transport pallet at the target pallet placement place (step S713) . If one conveying lot is not disposed in the corresponding conveying pallet, it is arranged at the head, and if there is a conveying lot already arranged, the conveying lot is arranged immediately thereafter. After that, the transportability instruction calculator 3 updates the remaining unit number of the target pallet placement place by subtracting the unit number of the target lot from the remaining unit number of the transport pallet at the target pallet placement place (step S715).

Then, the transportability instruction calculator 3 determines whether or not the lot loading order of the target lot is the last. If the lot loading order is not the last (step S717: No) (Step S719). Then, the transportability instruction instruction calculator 3 determines whether or not the remaining unit number of the target pallet placement place is " 0 " (step S721). When the remaining unit number is " 0 " (step S721: Yes), the conveying force instruction calculator 3 assigns a new conveying pallet to the target pallet placement place (Step S723), and moves the target pallet placement place to the next pallet placement place (step S725). After that, the process returns to step S709 and the above-described process is repeated.

On the other hand, if it is determined in step S709 that the lot fit sequential condition is not satisfied (step S709: No), the conveyance enabling instruction calculator 3 initializes the number of remaining units by allocating a new transport pallet to the target pallet placement place (Step S727), and moves the target pallet placement place to the next pallet placement place (step S729). After that, the process returns to step S709 and the above-described process is repeated.

If it is determined in step S711 that the target lot can not be placed (step S711: No), the portable effective part instruction calculator 3 determines whether or not the target lot can be placed in another pallet placement place other than the target pallet placement place (Step S731). If it is possible to place the pallet at any pallet placement place (step S733: Yes), the portable pallet instruction calculator 3 moves the target pallet placement place to the corresponding pallet placement place (step S735), and then goes to step S713 And the target lot is placed on the transfer pallet. On the other hand, when there is no other pallet placement place that can be arranged (step S733: No), the transportation allowance instruction calculator 3 sets a work constraint violation (step S737). Then, the process returns to step S7 in FIG. 12 after finishing the transfer pallet loading plan process, and thereafter, the process proceeds to step S8.

If it is determined in step S717 that the lot is in the final lot ordering process, that is, when all of the transport lots have been arranged (step S717: Yes), the process returns to step S7 in FIG. Thereafter, the process proceeds to step S8.

In step S8, the transportability instruction calculator 3 determines whether a work constraint violation is set in the transport pallet loading plan processing in step S7. When the work constraint violation is set in step S737 of Fig. 19 (step S8: Yes in Fig. 12), the process proceeds to step S13.

On the other hand, if the operation constraint violation is not set and the transport pallet loading plan has been created (step S8: No), the transportable part instruction calculator 3 executes the logistics cost calculation processing, (Step S9; evaluation value calculating step). Specifically, it is possible to calculate the logistics cost, which is an example of the evaluation value of the transport pallet loading plan, by using the evaluation function of " logistics cost " shown in Fig. 10, . Here, the evaluation function of the " logistics cost " shown in Fig. 10 is for outputting the logistics cost (yen / ton) by inputting the number of used pallets, for example. In the logistics cost calculation processing, Calculate the logistics cost based on the number of pallets used in the pallet load plan. If the logistics cost exceeds the target value and improvement is required (Step S11: Yes), the process proceeds to Step S13.

In step S13, the transportability instruction calculator 3 randomly generates an arbitrary value between the minimum value and the maximum value of the lotwise sequential condition shown in FIG. 9, changes the lotwise sequential condition (Setting change process), and then returns to step S7 and repeats the above process. By this processing, it is possible to repeatedly prepare the transfer pallet loading plan while changing the lot proper sequence condition without employing the transfer pallet 6 loading plan in which the logistics cost exceeds the target value, It can be adopted when the following conveying pallet loading plan is obtained.

On the other hand, if the logistics cost calculated in step S9 is equal to or lower than the target value and there is no need for improvement (step S11: No), the transportation allowance instruction calculator 3 executes result output processing as output means, The validation plan, that is, the loading plan prepared in step S3 and the transfer pallet loading plan created in step S7 are output to the database 4 and recorded as the work instruction file 48 (step S15; output step). The work instruction file 48 is notified of a shipment instruction or the like as a work instruction for the logistics equipment 6 that is properly required at the time of actual work.

As described above, in order to efficiently place the coil to be shipped in the holding window 171, if the carrying pallet exceeding the maximum pallet number of pallets is not placed at the pallet placement place, It is necessary to properly load the coil to be shipped on the transport pallet and carry it from the product warehouse 11 to the inner wall in order to prevent the occurrence of a situation.

According to the first embodiment, it is possible to plan the proper order of the coil to be shipped to the ship 17 and create the transportation pallet loading plan on the basis of this proper procedure, And the number of transfer pallets to be placed at the pallet placement place is limited to the maximum number of pellets to be placed in the pallet placement place Of the work done by the worker is not violated. Further, the transfer pallet loading plan can be repeatedly prepared while changing the lot valid sequential condition until the transfer pallet loading plan having the logistics cost less than the target value is obtained, so that the transfer pallet loading plan can be repeatedly generated, Reduction can be planned. According to this, it becomes possible to create a transportability plan of an optimal shipment target product with good efficiency as a whole in the proper work.

(Embodiment 2)

In the first embodiment, the case where the thin plate coil is transported to a single unloading port has been described. However, the present invention can also be applied to the case of creating a transporting compartment plan for the unloading plan including the thin plate coils discharged at different unloading ports . Hereinafter, as the second embodiment, the transportation compulsory plan creating processing in this case will be described. In the description of the second embodiment, the same reference numerals are given to the same components and process steps as those in the first embodiment.

When there is a thin plate coil to be applied to one ship, that is, a thin plate coil which is a coil to be shipped defined by one shipping schedule, there is a difference in terms of the unloading term, the balance center of the ship 171 is not shifted, It is necessary to take measures to ensure that. However, even if the unloading term is a single term, as described in Embodiment 1, the order of arranging the lines into the loading window 171 is adjusted in order to secure the balance of the vessel 17. In this case, when the average unit weight of the group of coils discharged from both ports is small, the group of coils having the smallest unit weight is transferred first, so that the arrangement order of the lines Adjustment is sufficient. However, in the case where the average unit weight of the group of coils to be released later is smaller, in addition to the above-mentioned countermeasures, another countermeasures such as shortening the first unit to the upper unit is necessary. Thus, in the second embodiment, a docking station plan for appropriately shortening the thin plate coil according to the number of unloading terms is created. Hereinafter, a case in which the thin plate coil is two-tiered (two-tiered) is exemplified.

20 is a flowchart showing the procedure of the transportation availability planning processing in the second embodiment. Here, in the second embodiment, the data structure of the product information file 41a in the database 4a included in the transportation availability planning system 2 is different from that in the first embodiment. 21 is a diagram showing a data configuration example of the product information file 41a in the second embodiment. As shown in Fig. 21, in the product information file 41a, the product information and the warehouse information are set in association with the product ID, similarly to the first embodiment. In the product information file 41a, a releasing group order is newly set as product information. The releasing group order indicates the opening order (releasing order) of the releasing term in which the corresponding thin plate coil is released, and the earlier the releasing group order is, the earlier the releasing order is released.

In the second embodiment, the transportation allowance instruction calculator 3 carries out the transportation allowable plan creating method by executing the transportation allowable plan creating processing in accordance with the processing procedure of FIG. In the transportation availability planning process, the transportation availability instruction calculator 3 executes the shipping facility planning process for both the ports after the shipping data input process in step S1, and transmits the job constraint file 44 and the dock information file 45 (Step S4). ≪ tb > < TABLE > Specifically, the transportation allowance instruction calculator 3 refers to the work constraint file 44 and the dock information file 45, and classifies the shipment target coils according to the respective planes on the basis of the plan supply data input in step S1 Later, a line is created, and a proper order is assigned to the coil to be shipped. Fig. 22 is a flowchart showing a processing procedure of the loading compartment planning process for each of the two load ports.

In the retainment allowance planning process for each port, the transportability instruction calculator 3 refers to the releasing group order of all the to-be-shipped coils and determines whether or not both ports are plural. If all of the coil groups to be shipped are the same, that is, if there are one unloading term (step S401: Yes), the loading compartment planning processing is executed in the same manner as step S3 of Fig. 12 described in the first embodiment ). After that, finishing processing of the loading conditions for both of the ports is completed, and the flow returns to step S4 in Fig. 20, and the flow proceeds to step S5.

On the other hand, when there are a plurality of both the in-charge numbers (step S401: No), the portable tofu instruction calculator 3 classifies the to-be-shipped coils for each of the inlets, that is, in the in-off group order (step S405). Then, the transportability instruction calculator 3 calculates the average unit weight of the group of coils for each classified grouping order, and sorts the groups of coils for each of the groups in ascending order of the average unit weight so that the average unit weight ascending order It is judged whether or not it matches the releasing group order. In the case of coincidence (step S407: Yes), the coil group having a small average unit weight is first released, and no special countermeasures are required as described above. Therefore, the transportable part instruction calculator 3 proceeds to step S403 And carries out the slotting compulsory planning process in the same manner as the mode 1.

On the other hand, when the average unit weight ascending order of the coil group for each releasing group order does not coincide with the releasing group order (step S407: No), the conveying force instruction calculator 3 determines that all of the coil groups (Step S409), and branches the processing according to the determination result.

Whether or not the two stages can be determined is determined by using two operation constraints relating to the work process in the " dock " when performing the " two-stage " In this case, the weight and outer diameter of the coil to be shipped in the releasing group order are successively compared with the weight and outer diameter of the coil to be shipped in the coil group after the releasing group order, and the weight If both of the difference between the vehicle height and the outside light weight fall within a predetermined allowable range, it is judged that the vehicle can be two-folded.

Fig. 23 is a diagram for explaining the procedure of the rewinding unit plan when all of the coil groups in which the releasing group order is in front are two-stage. In this case, as shown in Fig. 23, the coil group after the releasing group order is referred to as a first-stage coil, and the first- , n-1, n, while the coil group in which the releasing group order is in front is set as the second-stage coil and the second- , n-1, n are created. The line creation procedure itself can be performed in the same manner as in the first embodiment. The second-stage line may be configured according to the position in the first-stage line of the first-stage coil determined to be two-stage for each of the coil groups. The arrangement order of the first-stage line in the hold 171 is determined in consideration of the center of gravity in the hold 171 as in the first embodiment. After that, the order of the first-stage coil is sequentially assigned to the first-stage coil from the first-stage line to the first-stage coil. If the second stage coil has been repeatedly used up to the first stage line n, the sequential ordering of the second stage coil is sequentially assigned to the second stage line in order from the second stage line 1.

As shown in Fig. 22, when the conveyance enabling instruction calculator 3 judges that all of the coil groups preceding the releasing group order are two-stage permissible (Step S411: Yes) (Step S413), and the second group of coils is set as the second group coil (step S415). Then, the transportability instruction instruction calculator 3 assigns the order of application to all the to-be-shipped coils in the above-described manner (step S417). After that, finishing processing of the loading conditions for both of the ports is completed, and the flow returns to step S4 in Fig. 20, and the flow proceeds to step S5.

Fig. 24 is a diagram for explaining the order of the rewinding unit planning in the case where any of the coil groups whose order of releasing group is in front is two-stage impossible. In this case, as shown in Fig. 24, the upper and lower end lines 1, 2, ..., , n-1, n are created. The line creation procedure itself can be performed in the same manner as in Embodiment 1. At this time, it is possible to select a combination of the upper and lower stages, which can be two stages in the coil group in front of the releasing group order, Upper and lower lines of a pair of upper and lower lines are sequentially created. Separately, a combination of the upper and lower stages, which can be two stages, is selected from the coil groups after the releasing group order, and the upper and lower stages of the upper and lower stages composed of only the coil to be shipped after the releasing group order are created. The arrangement order of the upper and lower end lines in the hold 171 is determined in consideration of the center of gravity in the hold 171 as in the first embodiment. After that, for the first-stage coil constituting the lower end of the created upper and lower end lines, the order of the upper and lower end lines is sequentially arranged from the upper and lower end lines 1 in order. For the second stage coil constituting the upper stage, if the sequence is repeated up to the upper and lower stage line n, the order of the rearrangement is sequentially arranged from the upper and lower stage lines 1 to the upper and lower stage lines.

As shown in Fig. 22, in the case where it is determined that any of the coil groups in which the releasing group order is in front is two-stage impossible (Step S411: No), the transfer enabling instruction calculator 3, as shown in Fig. 22, Upper and lower end lines are created for the preceding coil group (step S419). Further, the transportability instruction calculator 3 creates upper and lower end lines for the coil group after the releasing group order (step S421). Then, the transportation allowance instruction calculator 3 assigns the correct order to all the to-be-shipped coils in the above-described manner (step S423). After that, finishing processing of the loading conditions for both of the ports is completed, and the flow returns to step S4 in Fig. 20, and the flow proceeds to step S5.

As described above, according to the second embodiment, even in the case of a shipment schedule including a coil to be shipped that is released at different ports, the shipment of the coil to be shipped first from both ports in the first shipment can not be shipped It is possible to plan the proper order of the coil to be shipped to the dock 171 in which the equilibrium of the ship 17 is secured while preventing the situation that the lower end of the target coil is applied.

The transportability planning method and the transportability planning apparatus according to the present invention can be applied to a process of transporting a product to be shipped and creating a transportability plan of the product to be shipped for proper operation to ship the product to the ship.
