The third step 240 includes a third receiving place 241, a third facility 242, and a third payout place 243.

  In the production line 200 shown in FIG. 2, a material to be transported for producing a product is first transported from the material supply source 210 to the storage site 260 or the first receiving storage site 221 of the first step 220 by, for example, a carriage. . The transported material transported to the first receiving place 221 is processed by the first equipment 222 and placed in the first payout place 223.

  The material to be transported placed in the first payout place 223 is transported to the place 260 or the second receiving place 231 in the second step 230 by the carriage. The transported material transported to the second receiving place 231 is processed by the second equipment 232 and placed in the second paying place 233.

  The material to be transported placed in the second payout place 233 is transported to the place 260 or the third receiving place 241 in the third step 240 by the carriage. The transported material transported to the third receiving place 241 is processed by the third facility 242 and placed in the third payout place 243.

The transported material transported from the first payout place 223 to the place 260 is transported to the external place 280 via the second receiving place 231 or the relay place 270 by the carriage. The material to be transported that has been transported from the second dispensing place 233 to the place 260 is transported to the external place 280 via the third receiving place 241 or the relay place 270 by the carriage.

  When the storage amount of the storage space 260 mainly reaches the threshold value obtained by subtracting a predetermined margin from the upper limit stock amount that can be stocked, the stock amount of the first reception space 221 or the second reception space 231 or the third reception space 241; Used. In addition, a material to be transported that is not scheduled to be processed by the first facility 222 in the near future is transported from the material supply source 210 to the storage site 260. The external storage site 280 is mainly used when the stock amount of the storage site 260 reaches a threshold value obtained by subtracting a predetermined margin amount from the upper limit stock amount that can be stocked.

  A material to be transported (material) for producing a product is transported to the material supply source 210 from the outside. The transported material (product) placed in the third dispensing place 243 is transported to the shipping place 250. However, since the physical distribution management support apparatus according to the present embodiment supports physical distribution management for transporting a material to be transported within the production line 200, such transport is not considered.

  As shown in FIG. 1, the physical distribution management support apparatus 100 according to this embodiment includes a display unit 110, an input unit 120, a memory 130, a storage unit 140, and a central processing unit (CPU) 150. The physical distribution management support apparatus 100 is configured by a personal computer, for example.

  The display unit 110 includes, for example, a liquid crystal display panel. The display unit 110 is controlled by the CPU 150 to display an alarm message or the like as will be described later. The display unit 110 is not limited to a liquid crystal display panel. The display unit 110 may include other panels such as an organic EL (electroluminescence) panel.

  The input unit 120 includes, for example, a mouse or a keyboard. When operated by the user, the input unit 120 outputs an operation signal indicating the operation content to the CPU 150. When the display unit 110 is a touch panel display, the touch panel display may also serve as the input unit 120 instead of the mouse or the keyboard.

  The memory 130 is configured by, for example, a semiconductor memory. The memory 130 includes, for example, a read only memory (ROM), a random access memory (RAM), an electrically erasable / rewritable ROM (EEPROM), and the like. The ROM of the memory 130 stores the control program of this embodiment that causes the CPU 150 to operate.

  The CPU 150 operates according to the control program of the present embodiment stored in the memory 130, thereby having functions of a reference physical distribution table generation unit 151, a variable distribution table generation unit 152, a variable flow rate determination unit 153, and an alarm issuing unit 154. . Specific functions of each unit of the CPU 150 will be described later. The physical distribution management support apparatus 100 may include other hardware that performs the same function instead of the CPU 150.

  The storage unit 140 is configured by, for example, a hard disk or a semiconductor memory. The storage unit 140 includes a production plan storage unit 141 and a progress information storage unit 142. Each of the storage units 141 and 142 may be composed of different media. Alternatively, each of the storage units 141 and 142 may be configured by a single medium in which the storage area is divided.

  FIG. 3 is a diagram schematically illustrating an example of the production plan 300 stored in the production plan storage unit 141. The production plan 300 represents a planned processing amount in each process of a certain period T and a planned flow rate between each process of the same period T and between a process and a place. As shown in FIG. 3, 100 units of material to be transported (material) are transported to the material supply source 210 from the outside.

  Of these 100 units, 80 units are transported to the first step 220 from the material supply source 210 as they are used immediately, and 20 units are transported to the place 260 as they are used in the future. Forty steps are transported from the yard 260 to the first step 220 as they are used immediately. In the first step 220, 120 units of the material to be transported are processed. The 120 units of materials to be transported that have been processed in the first step 220 are transported to the second step 230 as they are.

  In the second step 230, 120 units of material to be transported are processed. Of the 120 units of materials to be transported that have been processed in the second step 230, 60 units are transported to the yard 260 for immediate use, and 60 units are transported to the third step 240 for future use. Is done. In the third step 240, 20 units are transported from the storage place 260 as part of the immediate use. In the third step 240, 80 units of material to be transported are processed.

  On the other hand, 10 units are transported from the storage site 260 to the external storage site 280 via the relay storage site 270, and 10 units are transported from the external storage site 280 to the storage site 260 via the relay storage site 270. The contents of inventory are replaced by this transportation.

  Here, an overview of product production in the production line 200 will be described with reference to FIGS. A material to be transported is transported to the material supply source 210 from the outside. At this stage, the material to be transported is a material for producing a product. This material is first processed in a first step 220 into an intermediate product (also referred to as “semi-finished product”). Thereafter, the intermediate product is processed in a second step 230. Finally, the intermediate product is processed in the third step 240 to become a product. In the present specification, these “material”, “intermediate product”, and “product” are collectively referred to as “conveyed material”.

  In each process 220, 230, and 240 in the production line 200, the material to be transported from the previous process is matched to the own process from the viewpoint of manufacturing method, manufacturing conditions, quality stability, productivity, and production efficiency. Reorganization into the group (lot) is performed and processing such as processing is performed.

  The production efficiency in each process 220, 230, 240 differs depending on the lot. For example, the process in the first step 220 may proceed faster than the process in the second step 230. In order to absorb such a difference in production time between the lot organization time and each process 220, 230, 240, a relatively small receiving yard 221, 231 is provided on the receiving side of each process 220, 230, 240. , 241 are provided. Using these receiving places 221, 231, and 241, lot organization is performed, the difference between the order of arrival and the order of processing is absorbed, and processing is executed in each facility 222, 232, and 242.

  On the other hand, relatively small payout places 223, 233, and 243 are also provided on the payout side of each step 220, 230, and 240. Then, the intermediate product is transported in accordance with the lot organization and production pace of the next process within the limits of the upper limit stock quantity that can be stocked in the payout places 223, 233, and 243. That is, for example, lot organization and production pace adjustment in the second step 230 are performed in the first payout place 223 in the first step 220 and the second receiving place 231 in the next second step 230.

  In addition, when the difference between the lot organization time and the production pace cannot be absorbed only by the receiving place 221, 231, 241 and the paying place 223, 233, 243 of each process 220, 230, 240, a physical distribution device such as a cart is used. The intermediate product is transported to a larger yard 260.

  For example, when the processing amount in the second step 230 exceeds the processing amount in the third step 240, only the necessary amount of intermediate products is immediately sent directly to the third step 240, and the remaining intermediate products are transported to the storage place 260. The Then, when it becomes necessary, the intermediate product is transported from the storage place 260 to the third step 240.

  Alternatively, when the intermediate product is directly sent from the second step 230 to the third step 240, if the upper limit inventory amount that can be stocked in the third receiving place 241 of the third step 240 is exceeded, the intermediate product is temporarily placed in the place 260. When it becomes necessary, it is detoured such as being transported from the storage site 260 to the third step 240.

  Basically, it is preferable that the material to be transported is sent directly in the order of the first step 220 → the second step 230 → the third step 240. However, as described above, temporary detouring using the parking place 260 may be performed. In addition, since there is a limit to the upper limit inventory amount of the parking lot 260, the intermediate product is transported and stored in the external parking lot 280 via the relay parking lot 270 using logistics equipment such as trucks, and becomes necessary. The external storage 280 may be taken back to the processes 220, 230, and 240.

  In the example of FIG. 3, the direct feed rate in transporting the transported material from the first process 220 to the second process 230 is 100%, but in transporting the transported material from the second process 230 to the fourth process 240. The direct delivery rate is 50%. The total amount of material flow is 80 + 120 + 60 = 260 on the direct transmission line, 140 on the round trip to the parking place 260, and 40 on the round trip to the external parking place 280, including the amount via the relay parking place 270. Therefore, a total of 440 [units / T]. In addition, the stock amount of the parking lot 260 is increased by 20 [unit / T] because the payout amount is 10 + 40 + 20 = 70 and the received amount is 10 + 20 + 60 = 90.

  It is advantageous in terms of physical distribution that the direct feed rate in transporting the transported material is high, and that the transported material is less reciprocated between the storage site 260 and the external storage site 280. However, in consideration of the lead time between the processes, the manufacturing risk, and the like, it is meaningful to hold the stock of the material to be transported in the intermediate place 260 and the external place 280.

  FIG. 4 is a diagram schematically showing the standard physical distribution table 400 generated by the standard physical distribution table generating unit 151. The standard physical distribution table generation unit 151 generates the standard physical distribution table 400 based on the production plan 300 (FIG. 3) stored in the production plan storage unit 141.

  The reference physical distribution table 400 represents the number of units of the material to be transported from the transport source 401 to the transport destination 402 during a certain period T. In other words, the material to be transported that is dispensed from the transport source 401 is received by the transport destination 402. The total payout amount 403 represents the total number of units of the material to be transported paid out from each transport source 401. The total received amount 404 represents the total number of units of the transported material that each transport destination 402 accepts.

  For example, 80 [unit / T] is transported from the material supply source 210 that is the transport source 401 to the first process 220 that is the transport destination 402, and 20 [unit / T] is transported to the place 260 that is the transport destination 402. The Therefore, the total payout amount 403 of the material supply source 210 which is the transport source 401 is 100 [unit / T]. These are consistent with the production plan 300 shown in FIG. In other words, the standard physical distribution table 400 represents the production plan 300 in a table format.

  The item in the lower right corner of the standard physical distribution table 400 (440 [unit / T] in FIG. 4) represents the sum of the total payout amount 403 and the total received amount 404, that is, the total amount of the physical flow rate.

  Note that, as described above, the physical distribution management support apparatus according to the present embodiment supports the physical distribution management for transporting the material to be transported in the production line 200. Therefore, the standard physical distribution table 400 of FIG. 4 does not include the received amount of the material supply source 210 and the payout amount of the third step 240.

  With reference to the standard physical distribution table 400 of FIG. 4, conditions and the like to be observed regarding physical distribution are described. First, the ability to carry the total amount of material flow will be described. As described above, the item in the lower right corner of the reference physical distribution table 400 where the total payout amount 403 and the total received amount 404 intersect represents the total amount of the physical flow rate. In the case where these are transported by a cart, if the upper limit of stacking capacity per unit is 10 [units / unit], 44 [units] are required. Further, if the carriage is 20 [units], 2.2 rotations are required for a certain period T as the rotation rate of the carriage.

The upper limit M1 of the carrying capacity of the carriage is
M1
= (Upper load capacity / unit) x (Number of units) x (Number of revolutions / Period) x (Margin rate) (1)
It is represented by The total amount of the object flow needs to be equal to or less than the upper limit value M1 of the carrying capacity of the carriage. The upper limit value M1 of the carrying capacity represented by the expression (1) is stored in, for example, the ROM of the memory 130 (corresponding to an example of the carriage storage unit) as data included in the control program of the present embodiment, for example. Yes.

  In equation (1), (number of revolutions / period) represents the rotation rate of the carriage. The rotation rate of the carriage is set in advance using past performance data, for example. The rotation rate of the carriage may be set to a value that can be realized by the user based on past experience, for example. In equation (1), (margin ratio) represents “margin” set in consideration of various uncertain factors with respect to the upper limit of physical distribution capacity. The (margin ratio) is a coefficient less than 1, such as 0.95.

  Next, the ability to receive and pay in the parking place 260 will be described. The receiving of the transported material transported to the storage site 260 by the carriage to the storage site 260 and the dispensing of the transported material transported from the storage site 260 from the storage site 260 are performed using, for example, a logistics device such as a crane. . Since the total payout amount 403 in the storage place 260 is 70 [unit / T] and the total received amount 404 is 90 [unit / T], the total payout amount is 160 [unit / T]. When receiving and paying out at the yard 260 are performed by a plurality of cranes, a receiving / paying capacity equal to or greater than the total amount received / paid is required.

The upper limit M2 of the receiving and paying capacity by the crane is
M2
= Σi {(operation capacity of crane i) × (total operation time during a certain period T)} (2)
It is represented by The total amount received and paid needs to be less than or equal to this upper limit value M2. The upper limit value M2 of the receiving / paying capacity by the crane represented by the expression (2) is stored in, for example, a ROM of the memory 130 (corresponding to an example of the receiving / paying capacity storage unit) as data included in the control program of the present embodiment, for example. ing.

  In Formula (2), the operating capacity of a crane is represented by the number of units per unit time. In the above equation (2), the margin is included in the operating capacity of the crane. Alternatively, the margin rate may be multiplied without including the margin rate in the operating capacity of the crane.

  In addition, when receiving and paying out using different logistics equipment, it is necessary to evaluate receiving and paying separately. For example, in the case of the second process 230, the total payout amount 403 is 120 [units / T] and the total received amount 404 is 120 [units / T], so it is necessary to evaluate the payout ability and the receiving ability separately. There is.

  Next, the inventory amount at the storage location will be described. For example, in the place 260, if (acceptance amount−payout amount) is a positive value, the inventory amount increases, and if it is a negative value, the inventory amount decreases. In the example of FIG. 4, since the total received amount 404 of the place 260 is 90 [unit / T] and the total payout amount 403 is 70 [unit / T], the stock amount of the place 260 is 20 [unit / T]. ]To increase.

  For example, in the receiving yards 221, 231, and 241 of the processes 220, 230, and 240, if (acceptance amount−production amount) is a positive value, the inventory amount increases, and if it is a negative value, the inventory amount decreases. In the example of the second step in FIG. 4, the total received amount 404 of the second step 230 (second receiving place 231) is 120 [unit / T], and the processing amount of the second step 230 is as shown in FIG. 120 [unit / T], the stock amount of the second receiving place 231 in the second step 230 does not change.

  For example, in the payout storage locations 223 and 233 of the steps 220 and 230, if (production amount−payout amount) is a positive value, the stock amount increases, and if it is a negative value, the stock amount decreases. In the example of the second step in FIG. 4, the total payout amount 403 of the second step 230 (second payout storage 233) is 120 [unit / T], and the processing amount of the second step 230 is as shown in FIG. Therefore, the stock amount of the second payout storage 233 in the second process 230 does not change.

An inventory upper limit amount, which is an upper limit amount that can be stocked, is determined in advance for each place. In addition, a margin amount is set in advance for each storage location with respect to the stock upper limit amount. The threshold value obtained by subtracting the margin amount from the stock upper limit amount is stored in, for example, a ROM of the memory 130 (corresponding to an example of a threshold storage unit) as data included in the control program of the present embodiment, for example. In each place,
(Inventory after increase) ≤ (threshold) (3)
It is necessary to satisfy.

  FIG. 5 is a diagram schematically illustrating an example of the variation information 600 stored in the progress information storage unit 142. The fluctuation information 600 represents, for example, an actual amount resulting from a change in the production progress status with respect to the production plan 300 (FIG. 3). The fluctuation in the production progress status with respect to the production plan 300 (FIG. 3) mainly refers to a delay in progress with respect to the production plan 300 (FIG. 3). The delay in progress with respect to the production plan 300 (FIG. 3) is due to circumstances that were not assumed when the production plan 300 (FIG. 3) was formulated, such as a decrease in productivity due to equipment troubles, a sudden change in production order, and the like. Arise.

  Alternatively, the fluctuation information 600 may represent, for example, an expected amount when it is found that the production progress status fluctuates with respect to the production plan 300 (FIG. 3). The fluctuation information 600 represents a fluctuation processing amount in each process of a certain period T, and a fluctuating substance flow rate between each process of the synchronization period T and between the process and the place.

  In the example of FIG. 5, the variable processing amount does not change from the planned processing amount shown in the production plan 300 (FIG. 3). On the other hand, the transport amount of the transported material from the second process 230 to the third process 240 is reduced from 60 [unit / T] to N1 [unit / T]. The reduction width Δ from the planned flow rate 60 [unit / T] to the variable flow rate N1 [unit / T] can be obtained by Δ = 60−N1.

  Since the transport amount of the transported material from the second step 230 to the third step 240 is reduced from 60 [unit / T] to N1 [unit / T], the processing in the third step 240 (80 The transportable material for [unit / T]) is insufficient. Therefore, the transport amount of the transported material from the storage site 260 to the third step 240 increases to N2 = 20 + Δ [unit / T]. Further, in order to maintain a constant inventory amount in the second payout depot 233 (FIG. 2) in the second step 230, the transport amount from the second step 230 to the depot 260 is increased to N3 = 60 + Δ [unit / T]. To do.

  Thus, in the example of FIG. 5, the direct feed rate of the material to be transported from the second process 230 to the third process 240 is reduced. Due to this decrease, the total amount of the object flow rate is increased by Δ. In addition, although the inventory amount of the parking place 260 has not changed, the amount received and received has increased by 2Δ. Thus, the flow rate of goods is increasing due to a decrease in the direct feed rate.

  FIG. 6 is a diagram schematically showing the variable distribution table 700 generated by the variable distribution table generation unit 152. The variable physical distribution table generation unit 152 generates the variable physical distribution table 700 based on the fluctuation information 600 (FIG. 5) stored in the progress information storage unit 142. The fluctuating logistics table 700 represents the fluctuating information 600 (FIG. 5) in a tabular format, similar to the standard logistics table 400 (FIG. 4).

  The transportation source 701, the transportation destination 702, the total paid-out amount 703, and the total received amount 704 in the variable physical distribution table 700 are respectively the transportation source 401, the transportation destination 402, the total paid-out amount 403, and the total received amount in the standard physical distribution table 400 (FIG. 4). It is the same as the quantity 404. Note that the fluctuating physical distribution table 700 actually includes numerical values such as 120 and N1. Then, for example, the reduction width Δ can be obtained by Δ = 60−N1 as compared with the reference physical distribution table 400 (FIG. 4) as described above. However, in the fluctuating physical distribution table 700 of FIG. 6, it is described using Δ for convenience of explanation.

As described with reference to FIG. 5, the total amount of the variable flow rate, which is the total amount of the physical flow rate in the variable logistics table 700, is from 440 [unit / T] to 440 + Δ [unit / unit] in the standard logistics table (FIG. 4). T]. The variable substance flow rate determination unit 153 determines the magnitude of the total amount (440 + Δ) of the variable substance flow rate and the upper limit value M1 of the conveyance capacity of the above equation (1). The variable substance flow rate determination unit 153
(440 + Δ)> M1
If so, it is determined that the variable flow rate exceeds the upper limit flow rate that is the upper limit of the flow rate at which product production is not hindered. The variable substance flow rate determination unit 153
(440 + Δ) ≦ M1
If so, it is determined to be OK. The variable substance flow rate determination unit 153 stores the determination result in, for example, the RAM of the memory 130.

The alarm issuing unit 154
(440 + Δ)> M1
If so, a message indicating that the total amount of the fluctuating substance flow rate exceeds the upper limit value M1 of the transport capability is displayed on the display unit 110, and an alarm is issued.

As described with reference to FIG. 5, the amount of receipt and payment at the storage place 260 is increased from 160 [unit / T] in the standard physical distribution table (FIG. 4) to 160 + 2Δ [unit / T]. The fluctuating substance flow rate determination unit 153 determines the magnitude of the amount of payment (160 + 2Δ) of the place 260 and the upper limit value M2 of the amount of payment according to the above equation (2). The variable substance flow rate determination unit 153
(160 + 2Δ)> M2
If so, it is determined that the variable flow rate exceeds the upper limit flow rate that is the upper limit of the flow rate at which product production is not hindered. The variable substance flow rate determination unit 153
(160 + 2Δ) ≦ M2
If so, it is determined to be OK. The variable substance flow rate determination unit 153 stores the determination result in, for example, the RAM of the memory 130.

The alarm issuing unit 154
(160 + 2Δ)> M2
If so, a message is displayed on the display unit 110 indicating that the amount received / paid at the yard 260 exceeds the upper limit M2 of the receiving / paying capacity, and an alarm is issued.

  The total payout amount 703 of the storage place 260 is increased from 70 [unit / T] in the standard physical distribution table (FIG. 4) to 70 + Δ [unit / T]. In addition, the total received amount 704 of the parking lot 260 also increases from 90 [unit / T] in the standard physical distribution table (FIG. 4) to 90 + Δ [unit / T]. Therefore, the inventory amount of the parking place 260 has not changed.

  The warning issuing unit 154 issues a warning by displaying on the display unit 110 a message indicating that the total amount of the object flow rate exceeds the upper limit value M1 of the carrying capacity. Alternatively, a sound generator is provided in the physical distribution management support device 100, and the alarm issuing unit 154 outputs a message from the sound generator indicating that the total amount of the material flow rate exceeds the upper limit value M1 of the carrying capacity. An alarm may be issued. Thereby, the alarm issuing unit 154 can notify the user of the cause of the alarm issuing.

  FIG. 7 is a diagram schematically showing a countermeasure example when an alarm is issued by the alarm issuing unit 154. The transport source 501, transport destination 502, total payout amount 503, and total received amount 504 in the countermeasure example 500 are the transport source 401, transport destination 402, total payout amount 403, and total received amount in the standard physical distribution table 400 (FIG. 4), respectively. Same as 404.

  In the countermeasure example 500, as shown in FIG. 7, the user reviews the logistics plan, and the amount of the material directly transported from the material supply source 210 to the first step 220 is displayed in the standard logistics table 400 (FIG. 4). On the other hand, Δ is increased. As a result, the transport amount of the transported material from the material supply source 210 to the placement site 260 is reduced by Δ, and the transport amount of the transported material from the placement site 260 to the first step 220 is decreased by Δ. As a result of this countermeasure, as shown in FIG. 7, the total amount of goods flow returns to 440 [unit / T], which is the same as the standard physical distribution table (FIG. 4), and the amount received and paid at the parking lot 260 is the standard physical distribution table (FIG. 4). It returns to the same 160 [unit / T]. Therefore, in the countermeasure example 500, the warning issuing unit 154 does not issue a warning.

  In order to realize the countermeasure example 500 shown in FIG. 7, it is necessary to review the production plan including the processing order, such as incorporating a large amount of the stock from the material supply source 210 into the processing plan in the first step 220. become.

  FIG. 8 is a diagram schematically showing a countermeasure example different from FIG. 7 when an alarm is issued by the alarm issuing unit 154. The transport source 801, transport destination 802, total payout amount 803, and total received amount 804 of the countermeasure example 800 are the transport source 401, transport destination 402, total payout amount 403, and total received amount, respectively, in the standard physical distribution table 400 (FIG. 4). Same as 404.

  In the countermeasure example 800, as shown in FIG. 8, the user reviews the logistics plan, and does not use the relay site 270 in transporting the material to be transported between the site 260 and the external site 280. The material to be transported is directly transported between 260 and the external storage place 280. As a result, the material flow rate between the storage place 260 and the external storage place 280 is reduced by 20 [unit / T]. As a result of this countermeasure, as shown in FIG. 8, the total amount of the object flow rate is 420 + Δ [unit / T]. However, the amount received and paid at the parking place 260 remains 160 + 2Δ [unit / T].

Therefore, in the countermeasure example 800 of FIG.
(420 + Δ) ≦ M1
And,
(160 + 2Δ) ≦ M2
If so, the warning issuing unit 154 does not issue a warning.

  In order to realize the countermeasure example 800 shown in FIG. 8, it is necessary to adjust the temporal timing of transporting the transported material between the storage place 260 and the external storage place 280. For example, when the operating time of the parking place 260 is 24 hours and the operating time of the external parking place 280 is 7:00 to 15:00, in order to complete payment during the operating time of the external parking place 280, It is necessary to adjust the time for receiving and paying.

  Further, when (160 + 2Δ)> M2, in order to increase the upper limit value M2 of the receiving / paying capacity of the place 260, it is necessary to take measures such as increasing the operating time of the logistics equipment and increasing the number of staff of the place 260. Become.

  In addition to the countermeasure examples 700 and 800 shown in FIGS. 7 and 8, when the alarm is issued by the alarm issuing unit 154, other measures such as increasing the transport capacity and the receiving / paying capacity of the logistics equipment can be considered. . Specifically, for example, measures such as adding a carriage, assisting transportation by a truck, adding a crane, extending an operation time, and increasing the number of logistics equipment workers can be considered. Whether or not to take these measures will be determined in consideration of additional costs.

  FIG. 9 is a diagram schematically showing an example different from FIG. 5 of the variation information stored in the progress information storage unit 142. The fluctuation information 900 represents, for example, an actual amount due to a change in production progress with respect to the production plan 300 (FIG. 3). Alternatively, the variation information 900 may represent, for example, an expected amount when it is determined that the production progress status varies with respect to the production plan 300 (FIG. 3). Similar to the fluctuation information 600 (FIG. 5), the fluctuation information 900 represents a fluctuation processing amount in each process of a certain period T, and a fluctuating substance flow rate between each process of the synchronization period T and between the process and the place.

  In the example of FIG. 9, the productivity of the third step 240 decreases, and the processing amount is changed from 80 [unit / T], which is the planned processing amount shown in the production plan 300 (FIG. 3), to N4 [unit / T]. is decreasing. This reduction width Δ can be obtained by Δ = 80−N4. Due to the productivity reduction in the third step 240, the transport amount of the transported material from the second step 230 to the third step 240 is reduced from 60 [unit / T] to N5 [unit / T]. The reduction width αΔ from the planned flow rate 60 [unit / T] to the variable flow rate N5 [unit / T] can be obtained by αΔ = 60−N5.

  The coefficient α represents the amount that affects the reduction amount 60-N5 of the transport amount from the second step 230 to the third step 240 in association with the productivity reduction amount Δ = 80−N4 of the third step 240. It is a thing. The coefficient α can be obtained by α = (60−N5) / (80−N4). This coefficient α can be interpreted as representing the degree to which the decrease in production volume in the third process 240 affects the flow rate of goods from the second process 230 to the third process 240. The coefficient α is a positive number less than 1, for example.

  Further, the transport amount of the transported material from the second process 230 to the storage site 260 increases from 60 [unit / T] to N6 [unit / T], and the transport of the transported material from the storage site 260 to the third process 240 is performed. The amount is reduced from 20 [unit / T] to N7 [unit / T]. Note that N6 = 60 + αΔ and N7 = 20− (1−α) Δ.

  As described above, in the example of FIG. 9, the processing amount is reduced due to the productivity reduction in the third step 240. Due to this decrease, the total amount of the object flow rate is reduced by (1−α) Δ. Further, the amount received and paid at the parking place 260 is increased by (2α-1) Δ. In addition, the inventory amount of the parking space 260 increases by Δ when the total payout amount is subtracted from the total received amount.

  FIG. 10 is a diagram schematically showing the variable distribution table 1000 generated by the variable distribution table generation unit 152. The variable logistics table generation unit 152 generates the variable logistics table 1000 based on the fluctuation information 900 (FIG. 9) stored in the progress information storage unit 142.

  The transport source 1001, transport destination 1002, total payout amount 1003, and total received amount 1004 of the variable logistics table 1000 are the transport source 401, transport destination 402, total payout amount 403, and total received amount, respectively, of the standard logistics table 400 (FIG. 4). It is the same as the quantity 404.

  As described with reference to FIG. 9, the total amount of the material flow decreases from 440 [unit / T] in the standard physical distribution table (FIG. 4) to 440− (1−α) Δ [unit / T]. ing. Therefore, the total amount of the object flow rate is maintained at the upper limit M1 or less of the carrying capacity.

As described with reference to FIG. 9, the amount of receipt / payment at the storage place 260 increases from 160 [unit / T] in the standard physical distribution table (FIG. 4) to 160+ (2α−1) Δ [unit / T]. ing. The variable flow rate determination unit 153 determines the magnitude of the amount of payment (160+ (2α−1) Δ) of the place 260 and the upper limit value M2 of the payment capacity of the above equation (2). The variable substance flow rate determination unit 153
(160+ (2α-1) Δ)> M2
If so, it is determined that the variable flow rate exceeds the upper limit flow rate that is the upper limit of the flow rate at which product production is not hindered. The variable substance flow rate determination unit 153
(160+ (2α-1) Δ) ≦ M2
If so, it is determined to be OK. The variable substance flow rate determination unit 153 stores the determination result in, for example, the RAM of the memory 130.

The alarm issuing unit 154
(160+ (2α-1) Δ)> M2
If so, a message is displayed on the display unit 110 indicating that the amount received / paid at the yard 260 exceeds the upper limit M2 of the receiving / paying capacity, and an alarm is issued.

  The total payout amount 1003 of the storage place 260 is reduced from 70 [unit / T] in the standard physical distribution table (FIG. 4) to 70− (1−α) Δ [unit / T]. Further, the total received amount 1004 of the parking lot 260 is increased from 90 [unit / T] in the standard physical distribution table (FIG. 4) to 90 + αΔ [unit / T]. Therefore, the inventory amount of the parking lot 260 has increased by Δ. The fluctuating substance flow rate determination unit 153 determines whether or not the stock amount after the increase Δ satisfies the above formula (3). If the stock amount after the increase in Δ does not satisfy the above formula (3), the variable material flow rate determination unit 153 determines that the variable material flow rate exceeds the upper limit material flow rate that is the upper limit of the product flow rate that does not hinder the production of the product. The fluctuating substance flow rate determination unit 153 determines that the stock amount after the increase in Δ satisfies the above expression (3), that is OK. The variable substance flow rate determination unit 153 stores the determination result in, for example, the RAM of the memory 130. If the above expression (3) is not satisfied, the alarm issuing unit 154 displays a message on the display unit 110 indicating that the inventory amount of the storage 260 exceeds the threshold value, and issues an alarm.

  FIG. 11 is a diagram schematically showing a countermeasure example when the stock amount after the increase of Δ exceeds the threshold value (does not satisfy the above formula (3)). The transport source 1101, transport destination 1102, total payout amount 1103, and total received amount 1104 of the countermeasure example 1100 are the transport source 401, transport destination 402, total payout amount 403, and total received amount, respectively, in the standard physical distribution table 400 (FIG. 4). Same as 404.

  In the countermeasure example 1100, as shown in FIG. 11, the user reviews the logistics plan and sets the transport amount to transport the transported material from the storage site 260 to the external storage site 280 via the relay storage site 270 by 10 [unit / T. ] To 10 + Δ [unit / T]. As a result of this countermeasure, the total payout amount 1103 of the parking lot 260 becomes 70 + αΔ [unit / T]. For this reason, the inventory quantity of the parking lot 260 becomes the same as the standard physical distribution table (FIG. 4). As a result, the inventory amount of the parking place 260 satisfies the above formula (3).

On the other hand, due to the countermeasure shown in FIG. 11, the total amount of the material flow rate increases to 440+ (1 + α) Δ [unit / T], which is larger than that in the reference physical distribution table (FIG. 4). Therefore, the variable material flow rate determination unit 153 determines the magnitude of the total amount (440+ (1 + α) Δ) of the material flow rate and the upper limit value M1 of the transport capability of the above equation (1). The variable substance flow rate determination unit 153
(440+ (1 + α) Δ)> M1
If so, it is determined that the variable flow rate exceeds the upper limit flow rate that is the upper limit of the flow rate at which product production is not hindered. The variable substance flow rate determination unit 153
(440+ (1 + α) Δ) ≦ M1
If so, it is determined to be OK. The variable substance flow rate determination unit 153 stores the determination result in, for example, the RAM of the memory 130.

The alarm issuing unit 154
(440+ (1 + α) Δ)> M1
If so, a message indicating that the total amount of the fluctuating substance flow rate exceeds the upper limit value M1 of the transport capability is displayed on the display unit 110, and an alarm is issued.

Further, as can be seen from FIG. 11, the amount received and paid at the storage place 260 is increased from 160 [unit / T] in the standard physical distribution table (FIG. 4) to 160 + 2αΔ [unit / T]. The fluctuating substance flow rate determination unit 153 determines the magnitude of the amount of payment (160 + 2αΔ) of the place 260 and the upper limit value M2 of the amount of payment according to the above equation (2). The variable substance flow rate determination unit 153
(160 + 2αΔ)> M2
If so, it is determined that the variable flow rate exceeds the upper limit flow rate that is the upper limit of the flow rate at which product production is not hindered. The variable substance flow rate determination unit 153
(160 + 2αΔ) ≦ M2
If so, it is determined to be OK. The variable substance flow rate determination unit 153 stores the determination result in, for example, the RAM of the memory 130.

The alarm issuing unit 154
(160 + 2αΔ)> M2
If so, a message is displayed on the display unit 110 indicating that the amount received / paid at the yard 260 exceeds the upper limit M2 of the receiving / paying capacity, and an alarm is issued. When an alarm is issued by the alarm issuing unit 154, countermeasures such as countermeasure examples 700 and 800 described with reference to FIGS. 7 and 8 are taken.

  In addition, the countermeasure when the stock quantity after Δ increase does not satisfy the above formula (3) is not limited to the example shown in FIG. For example, a measure may be taken to adjust the initial stock amount of the storage 260 so as to decrease in advance.

Then, the determination result is stored in the RAM 130 of the memory 130, for example. The fluctuating material flow rate determination unit 153 determines that the total amount of the material flow rate is OK if the total amount of the material flow rate is equal to or less than the upper limit value M1 of the conveyance capacity.

  In step S <b> 1210, the fluctuating substance flow rate determination unit 153 calculates the amount received / paid from the place 260 from the fluctuating logistics table 700. In step S <b> 1215, the fluctuating substance flow rate determination unit 153 determines the magnitude of the amount received and paid at the place 260 and the upper limit value M <b> 2 of the ability to receive and pay according to the above equation (2), and stores the determination result in, for example, RAM of the memory 130. The fluctuating material flow rate determination unit 153 determines that the received / paid amount of the place 260 is OK if the received / paid amount is equal to or less than the upper limit M2 of the receiving / paying capability.

  In step S <b> 1220, the variable substance flow rate determination unit 153 acquires the initial inventory amount of the storage place 260 from the information stored in the production plan storage unit 141. The fluctuating material flow rate determination unit 153 calculates the amount of change in the inventory amount of the storage 260 from the fluctuating logistics table 700. The fluctuating material flow rate determination unit 153 calculates the inventory amount of the placement 260 at the current time from the initial inventory amount of the placement 260 and the change amount of the inventory amount of the placement 260. In step S <b> 1225, the fluctuating substance flow rate determination unit 153 determines whether or not the current inventory amount of the storage place 260 satisfies the above formula (3), and stores the determination result in, for example, the RAM of the memory 130. The fluctuating material flow rate determination unit 153 determines that the stock amount of the storage place 260 satisfies the above expression (3).

  In step S1230, the variable substance flow rate determination unit 153 determines whether or not all the determination results are OK. If all the determination results are OK (YES in step S1230), the operation in FIG. 12 ends. If even one determination result is not OK (NO in step S1230), the process proceeds to step S1235. In step S1235, the warning issuing unit 154 issues a warning by notifying the type for which the determination result is not possible. For example, the alarm issuing unit 154 displays a message on the display unit 110 indicating that the total amount of the material flow exceeds the upper limit value M1 of the conveyance capacity. Thereafter, the operation of FIG. 12 ends.

  The operation shown in FIG. 12 is executed again when a production plan including a logistics plan is reviewed as a result of a warning issued by the warning issuing unit 154 and a countermeasure such as countermeasure examples 700, 800, 1100 is taken. That is, the operation of FIG. 12 is repeatedly executed until no warning is issued by the warning issuing unit 154.
