DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. 1 that are the same as those in the previous figure are given the same reference numerals.
In FIG. 1, the communication means 11 communicates with the parts maker 1, the contract manufacturing maker 2, the user 3 and the transportation means 5 in the distribution route. The management unit 12 obtains information regarding the status of physical distribution via the communication unit 11. The management unit 12 manages the quality of physical distribution by applying the physical distribution management index to the acquired information. Since the distribution management index is applied to the distribution status information acquired from the parts manufacturer 1 to the user 3, the distribution route from the supplier to the end user is managed seamlessly. here,
The management index of the distribution quality is, for example, the defective rate of the transportation, the delivery date of the delivery, the transportation cost, the inventory amount in the distribution route, and the like. The defective rate of transportation is the rate at which a good product before transportation becomes a defective product due to damage during transportation.

The database 13 stores data in which the sections constituting the physical distribution route are associated with the required transportation times in the sections. For example, in the database 13, data on sections A, B, C, D, E and data TA, TB, TC, T required for transportation in these sections are stored.
D and TE are stored in association with each other. Route construction means 14
Constructs a physical distribution route by connecting the section data accumulated in the database 13. For example, it is assumed that the distribution route from the supplier S to the end user U can be constructed by the section A + B + C or the section A + B + D. At this time,
The route construction means 14 lists the physical distribution route connecting the sections A, B, and C and the physical distribution route connecting the sections A, B, and D as candidates. The optimal distribution route is selected based on the time required for the distribution route listed as a candidate. In the former distribution route, the required transit time is TA + TB + TC, and in the latter TA +
It becomes TB + TD. Required time TA + TB + TC is TA +
When it is shorter than TB + TD, the route construction means 14 determines that the physical distribution route connecting the sections A, B, and C is the optimum route.

The route changing means 15 refers to the section data accumulated in the database 13 when a failure occurs in the physical distribution route while the physical distribution route constructed by the route constructing means 14 is being transported, and the A new distribution route is rebuilt from the middle of the constructed distribution route. For example, section A,
When a failure occurs in the section C in the distribution route connecting B and C, a new distribution route A + B + D in which the section C is replaced by the section D is reconstructed. At this time, the communication means 1
1 transmits the change instruction to the start point of the reconstructed section D (end point of section B).

The access permission means 16 permits the authenticated vendor or user to access the database 13. The browsing permission unit 17 provides the database 13 to the vendors or users who are permitted to access.
Permits browsing of specific data stored in. For example, the browsing permission unit 17 permits the vendor, to which access is permitted, to browse the evaluation data of this vendor. In addition, the browsing permission unit 17 permits a user who is permitted access to browse the quality data of the distribution service provided to the user. The data collection unit 18 collects data indicating the transportation status on the distribution route as needed. The collected data is stored in the database 13 as needed. The management means 12 applies a predetermined management index to the transportation status data stored in the database 13 at any time, and manages the quality of physical distribution. As a result, the transportation status data is stored in the database at any time, the contents of the database are updated at any time, and the management unit 12 applies the management index to the updated data to manage the physical distribution quality in real time.

FIG. 2 is a flow chart showing the operation procedure of the present invention. In FIG. 2, the part surrounded by the broken line is the operation on the information management center side, and the part outside the part surrounded by the broken line is the operation on the transportation means side. The operation will be described according to the steps of the flowchart.

First, the operation during operation will be described. (S1) The transportation means transmits data to the information management center at the time of passing through each section of the physical distribution route. (S2) In the information management center, it is determined by which item the transmitted various data have changed. Variable items include, for example, the season, the day of the week, the time zone, and the like. The required time varies depending on these variable items. (S3) The data collection unit 18 calculates the amount of fluctuation by calculating the received data and writes the calculation result in the database 13. In this way, the data acquired by the actual physical distribution is calculated and written in the database 13.

Next, the operation at the time of logistics planning (at the time of constructing a physical distribution route) will be described. In this operation, the route construction means 14 is responsible for the processing in the information management center. (S4) Target setting is performed. The target setting is to set a target management index, for example, to set the defective rate of transportation to be less than or equal to%, or to set the delivery error within how many hours. (S5) Analysis and calculation are performed by a quality control method to search for a physical distribution route that satisfies the targeted conditions. At this time, the database 13 is referred to and writing is performed. (S6) The data of the section and the required time in the database 13 are referred to. In addition, the optimal solution is calculated and the database 1
Write to 3. The optimal solution is the optimal distribution route.

The operation at the time of dynamic decision will be described. This operation is an operation of dynamically reconstructing a route when a failure occurs in the physical distribution route. In this operation, the processing at the information management center is route changing means 1
5 bears. (S7) The transportation means transmits data to the information management center when a failure occurs. (S8) The information management center determines a case to be applied from various cases. Then, the process branches according to the determination. (S9) Analysis and calculation are performed by the quality control method. At this time, the database 13 is referred to and writing is performed. (S10) The optimum solution is calculated by referring to the data of the section and the required time in the database 13. The optimal solution is the reconstructed optimal distribution route. Send the optimal solution to the vehicle. (S11) The transportation means receives the optimal solution and transports it along the physical distribution route based on the optimal solution.

Next, the procedure of distribution will be described. FIG. 3 is an explanatory view showing the procedure of physical distribution. The operation will be described according to the procedure shown in FIG. In the case of transportation from the parts supplier DC1 to the maker factory via the procurement route, in the case of normal transportation, the data of the procurement route is separately stored and accumulated for each distributor. For example, the distribution route, distribution means, cost, time zone, cost variation, transportation time variation, transportation time variation due to arrival time zone, etc. are stored separately. DC1 to D
Cn + 1 is a distribution center, and when a problem occurs during transportation of a procurement route that is a node of a distribution route and it is necessary to judge whether or not to change the route, it is sent via a mobile phone or the mobile Internet. Notify the information management center of delays. In response to this, the information management center separates and stores the data of the procurement route for each transportation company, and recalculates the optimal route, the optimal transportation means, etc. based on the accumulated data. The information management center notifies the re-calculated result to the transportation vehicle or the distribution center via the mobile phone or the mobile Internet. "Transportation vehicle" or "transportation means" that has undergone this recalculated "transportation means" or "delivery route" change
Is transmitted directly to the vehicle as a "change instruction" or is transmitted and executed as a "change instruction" at the distribution center. Whether or not the “change instruction” has been executed is notified to the information management center, and the information is updated as the latest information on the transportation state. Finally delivered to the end user.

FIG. 4 is a diagram showing an example of the data structure of the database 13. FIG. 4 shows a data structure when the transportation means is a vehicle. FIG. 4 has a data structure in which required time for transportation and its variation are associated with seasons, days of the week, time zones, directions, weather conditions, etc. for each road section. This data is data items -1 to -5 in (a) to (d) of FIG. A road section unit may be a distribution center (DC) as a node, or may be a node based on the road itself regardless of the presence or absence of a distribution center. In addition, data for required charges such as fuel costs and toll road costs and their variations are taken for each section.
This data is the data item shown in FIG.
In addition, it collects data on transportation quality and its variations due to damage to the cargo. This data is the data item shown in FIG. The transportation quality is the above-mentioned defective rate of transportation. It also collects data for each driver.

FIG. 5 is a diagram showing another example of the data structure of the database 13. FIG. 5 shows a data structure when the transportation means is a ship. In FIG. 5, for each route section unit, the same data items as in the case of the vehicle, -1--
5 to are provided. In FIG. 5, data items -2 are omitted for simplification. In addition to this,
Data items of connectivity (time required for connection) from the port to the shortest distribution center (DC) and road are also provided. This data is the time it takes to unload a package from a ship at the port, carry out the necessary procedures, reload the package into a vehicle and transport it to the shortest distribution center.

FIG. 6 is a diagram showing another example of the data structure of the database 13. FIG. 6 shows a data structure when the transportation means is an aircraft. In FIG. 6, the same data items as in the case of the vehicle, -1 to
-5 and are provided. In addition to this, data items of connectivity (time required for connection) from the airport to the shortest distribution center (DC) and roads are also provided.

FIG. 7 is a diagram showing an example of the data structure of the database 13. FIG. 7 shows a data structure when the transportation means is a railway. In FIG. 7, the same data items as in the case of rolling stock, for each rail section, -1 to-
5 to are provided. In addition to this, data items of the shortest distribution center (DC) from the railway station and the connectivity (time required for connection) with the road are also provided.

FIG. 8 is a diagram showing another example of the data structure of the database 13. FIG. 8 shows a database in which variations in data in each data item in FIG. 4 are taken.

A procedure for storing data in the database will be described. The database shown in FIG. 4 will be described as an example. Each time the vehicle of the trader A passes through each section, the data is stored in the database according to the items of FIG. 4 when the data is sent to the information management center by the communication means.
In the case of a vehicle, “section 1” in FIG.
Shows the average value of the required time for the whole year. This is divided into summer and winter-1, morning and afternoon-2, and further divided into fine weather and rainy weather and accumulated.

In FIG. 4, the clear weather correction value -3 is used, but this is calculated as a correction value at the time of fine weather with respect to the average required time of the year, which is obtained irrespective of the weather. Required time Sunny correction value (-
3) = The average time required for fine weather in a year, that is, the section 13.6h-0.2h = 3.4h can be obtained. As a way of holding data, it is theoretically equivalent to accumulate the average time required for fine weather in a year.

Similarly, for correction value -4 depending on the day of the week, average required time () + annual required time Monday correction value (-
4) = Average required time on Monday of the year Average required time () + Annual required time Tuesday correction value (-
4) = The average required time on Tuesday of the year can be calculated.

Also in the case of rain, the average required time () + annual required time rainy weather correction value (-
3) = Annual average time required for rain, that is, section 13.6h-0.5h = 3.1h can be obtained. The same applies to the day of the week, so the description is omitted.

Further, by separately preparing the day of the week correction values for each of the morning and afternoon of summer and winter, the summer average required time (-1) + summer required time Monday correction value (-3) = summer Monday average required time Average time required for winter (-1) + required time for winter Monday correction value (-3) = average required time for summer in summer Average required time for morning in summer (-1) + required time for morning in summer Monday correction value (-3) = for summer Monday morning average required time Winter morning average required time (-1) + winter morning required time Monday correction value (-3) = winter Monday morning average required time

The same calculation can be performed after Tuesday.
Also, the same calculation can be performed for rainy weather. In the present invention, how to hold the data in the traveling direction in the section 1 is defined by defining the reference value of the section as upstream data and expressing the downstream as a direction correction value (the upstream and downstream can be defined as another section). That is, in the case of section 1, it is possible to obtain the average annual required time () + the annual section (up reference vs. downward) direction correction value (−5) = the average required time for the section. (As a way of holding data, it is theoretically equivalent to accumulate the average downtime required for the section of the year.)

The required section fee depends on the trader, but is fixed for each section. Regarding transportation quality (average of traders), it may not be possible to calculate the quality such as damage of packages depending on the section because it is premised on inspection at each distribution center (DC). However, at least "variation" (see FIG. 8) such as required time can be adopted as quality. Transport quality will be maintained for each operator, but will be further accumulated for each driver.

Data obtained by means of transportation other than the vehicle are also shown in the ship of FIG. 5, the aviation of FIG. 6 and the railway of FIG. In addition to the case of the vehicle, in the case of FIG. 5 to FIG. 7, as the connectivity with the distribution center and the road, the time for switching and connecting from each transportation means to the vehicle is accumulated as data.

The variation of the data values stored in the database will be described. FIG. 8 shows the maximum value of the “variation” such as the average required time stored for each trader in FIG.
It takes the minimum value or standard deviation -d (Fig. 8).
Indicates an example of standard deviation). That is, the variation of the required time in the section 1 of the trader A is calculated as a standard deviation, and is calculated and updated every time it is saved. Therefore, the stored value has the latest standard deviation. The same applies to the case of the maximum value-minimum value. Similarly, for the other values in FIG. 4, the standard deviation is stored as an extension of FIG.

The operation when a failure occurs in the transportation route will be described. FIG. 9 is a diagram showing an example of a transportation route. When a trouble such as a delay occurs on the transportation route, it is notified according to the communication means as described in FIG. 3, and optimal by using the transportation route, transportation section, transportation time zone, and transportation quality accumulated in the database 13. The route calculation is performed for each transportation section, and it is transmitted to the transportation means to dynamically change the route, the transportation means and the transportation destination. Thereby, the productivity of the production process can be maintained for the EMS.

For example, in the case of only a vehicle, at the time of entering the section 2 from the section 1, the driver who is transporting the
A case will be described in which the information on the traffic obstacle is obtained and the request for the detour route is sent to the information management center in FIG. In the case of reaching from the destination to the destination in section 1, section 2, and section 7, if it is not necessary to consider the season, etc., the delivery date is: delivery date = section 1 + section 2 + section 7 = 3.6h + 3.9h + 2.6h = 10. A specific example is shown for the case where 1h is set to 11h (contract delivery date) with a margin of 0.9h. In the middle of section 1, when the information management center receives the information that the road cannot pass in section 2, the information management center performs the following calculation. Remaining; Section 2 + Section 7 = 3.9h + 2.6h =
6.5h Since the delivery time margin is 0.9h, the first candidate is the constraint condition; section 3 + section 4 = 2.6h + 4.0h = 6.h.
6h Delivery margin = 0.8h or second candidate; section 5 + section 6 = 3.6h + 3.2h = 6.
2 routes with 8h delivery margin = 0.6h are selected as candidates. Therefore, the designation of section 3 and section 4 is the optimum instruction from the information management center.

However, looking at the transportation quality, referring to the transportation quality (commercial average) in FIG. 4, section 3 + section 4 = 15 ppm + 24 ppm = 39 ppm section 5 + section 6 = 10 ppm + 10 ppm = 20 ppm For example, the transportation quality is “30 ppm or less”. If there is, only Section 5 + Section 6 is clear, and transportation time is early in Section 3 + Section 4, but it is not adopted because it does not reach the standard in terms of quality, so Section 5 + Section 6 is adopted as the optimum solution. It is shown to be an instruction to the driver.

In order not to disturb the customer's production process, the contract delivery time margin is constantly updated by the quality control method to constantly update the average value data of the period, and the delivery time margin is dynamically calculated even in the event of a sudden accident, and the optimum solution of the result is obtained. The delivery time is secured by notifying the driver of the transportation means. This is incorporated into the system to realize a quality control method. In other words, the goal of top-down is the delivery time margin that does not disturb the customer's production process, and updating the main time data every time the transportation means passes the specified section is a concrete approach,
The concrete action is to calculate the optimum solution and notify the driver of the transportation means when a sudden accident occurs.

At the transportation planning stage, for the EMS, a logistic means considering the accuracy of arrival of procured parts (components) due to production reasons is used, and the quality of the transportation company and the transportation company whose data is accumulated by the quality control method. By optimally selecting the relationship with the cost, it is possible to minimize the transportation risk and consequently minimize the inventory at the responsibility of the logistics company. This stock quantity determines whether or not the safety stock quantity can be suppressed, for example, how accurately a defect can be suppressed and a logistic company can deliver it at the production start date and time designated in the production plan in EMS.

For example, by having the data of the required time day correction -4 in FIG. 4, it is possible to predict the required time value in units of time or less for each section. When Supplier A is used for the parts transportation route from the supplier to EMS Section 1 + Section 2
If it is + section 3, in the case of Monday, from Fig. 4, the annual average average required time + required time Day correction -4 = Calculated by the required time on Monday of each section, section 1 + section 2 + section 3 = (3.6h + 0.6h ) +
(3.9h + 0.9h) + (2.6h-0.6h) = 1
1h Annual average required time Section 1 + Section 2 + Section 3 = (3.6h) + (3.9h)
With respect to + (2.6h) = 10.1h, an accuracy improvement of 0.9h can be expected. Therefore, if the safety stock for one day is used, 0.9h / 24h = 3.
A 75% improvement is expected. Actually, if the time of the operation target is taken into consideration, it is not 24 h but 12 h or less, so 0.
Significant improvement is expected with 9h / 24h = 7.7%.

In other words, if the top-down target is set to "reduce low-cost labor inventory by 10%", the approach is to prepare the data of FIG. 4 and calculate every time it is updated, and the error of the transportation time is ○. The concrete action is to explicitly set the goal in the system that it must be suppressed to 0%. This is implemented by being incorporated into the system. Although this safety stock was the goal of the logistics company itself, setting the safety stock of the user can be applied in the present invention in exactly the same manner.

Using a system for reducing the product defect rate, which is closed in the factory, the quality control method data in which the quality of product production including the logistic business areas on both the supplier side and the end user side is accumulated in advance is used. By performing quality simulation, it is possible to expand to the logistic area outside the factory and achieve and maintain the product quality until it reaches the end user.

For example, for the transportation quality shown in FIG.
In the above, defects occurred at an average ratio of 24 ppm. When this is taken as an example and the standard deviation of the transportation quality of the manufacturer A (average of the manufacturers) is observed, the defective rate is 3 ppm.
In this case, the section from the factory to the end user
If it is from section 1 to section 3, the transport quality is calculated by simple calculation and total 14ppm + 13ppm + 15ppm = 42p
pm. Similarly, the variation in transportation quality is 3 ppm + 0.5 ppm + 0.5 ppm = 4 ppm in total. Therefore, when transporting this section, it is expected that 42 + 4 = 46 ppm or more will be the transport quality by simple addition. If the standard transport quality specified by the end user is 70 ppm, 46 ppm <70 pp
It is expected that the standard can be cleared by m.

Therefore, since the transportation quality can be predicted in advance, the quality standard on the end user side can be followed by the simulation, so that, for example, lot defects can be prevented. It can be shown by simulation that the quality assurance value of a lot is extremely high (strict) and that the transportation quality has a large contribution to the quality deterioration, which causes a lot failure. In other words, although a simple production plan is universally implemented, a quality maintenance plan can be clearly and concretely created for the first time.

The top-down target is "the quality level of the parts to be prepared necessary for the user's production plan is XX ppm".
The quality control approach is to update the transportation quality data (for example, defective rate) for each section and store it in the database in order to achieve that quality level, and achieve the target quality level. The action of the quality control method is to determine the transportation route by an explicit procedure. This doesn't just stay inside the factory as before,
It is an important feature of the present invention to realize a system to reduce the product defect rate, including distribution companies outside the factory.

A database for a plurality of transportation means as shown in FIGS. 4 to 7 is prepared and the route changing means 1 is used.
If a failure occurs in the physical distribution route during transportation using the physical distribution route that has been constructed, 5 refers to the section data accumulated in the database and rebuilds the physical distribution route by changing the transportation means. Good.

The factors for changing the transportation route include the convenience of the late delivery user on the route, the convenience of the manufacturer and the factory, the weather of the distributor, and the like. The form of production may be any one such as procurement in which everything is provided in-house, separation of production and distribution, and outsourcing of production to EMS. The communication means may include any or all of mobile communication, the Internet, wired telephones, fax machines, and the like.

According to the present invention, the following effects can be obtained.

In the inventions according to claims 1 to 3, a predetermined management index is applied to a physical distribution route from a supplier (manufacturer supplying parts) to an end user,
Since the quality of logistics is managed seamlessly, it is possible to comprehensively improve the quality of logistics and the quality of production over the entire logistics route.

According to the fourth aspect of the present invention, the transportation status data is stored in the database at any time, the contents of the database are updated at any time, and the management means applies the management index to the updated data to manage the physical distribution quality in real time. . As a result, it is possible to realize a physical distribution management system that can make decisions in real time about all actions (risk avoidance, inventory reduction, etc.) Such a distribution management system has good consistency with the approach of quality control from the standpoint of the manufacturer as an end user.

In the inventions according to claims 5 to 8, a plurality of transportation routes or transportation means are prepared in advance, and when a failure occurs in the distribution route, an alternative transportation route or transportation means is used. This makes it possible to flexibly cope with obstacles in the distribution route.

According to the ninth aspect of the present invention, since the correction value for correcting the variation in the required time of the physical distribution is stored in the database, it is optimal in consideration of the influence of various factors such as the season, the day of the week, and the weather. A distribution route can be constructed.

According to the tenth aspect of the invention, since the vendor or the user who is permitted to access the data is permitted to browse the specific data stored in the database, the data that is specific to the specific vendor or the user is specified. I can show you. For example, in the case of a vendor, it is possible to show only specific data such as the company's own data or only its own evaluation ranking, and in the case of a user, the vendor's unique name to the logistic company is hidden but the logistic company's comprehensive quality data is displayed. it can.

In the eleventh aspect of the present invention, the browsing permission means permits the vendor, to which access is permitted, to browse the evaluation data of this vendor. For this reason, the vendor's evaluation index and evaluation value are shown to the vendor in real time, the vendor can know how the vendor is evaluated, and the vendor's efforts can be encouraged.

According to the twelfth aspect of the present invention, the browsing permission means permits the user who is permitted access to browse the quality data of the distribution service provided to the user. This makes it possible to provide the user with a basis for increasing the added value of transportation by making the quality of transportation open.
