The control unit 11 is a processor such as a CPU (Central Processing Unit) or GPU (Graphics Processing Unit) of the management device 1, and the contact management unit 110 and the supply amount are acquired by executing the program stored in the storage unit 10. It functions as a unit 111, a usage status acquisition unit 112, a demand amount acquisition unit 113, a deviation degree acquisition unit 114, and a notification unit 115.

Note that FIG. 2 shows an example in which the management device 1 is composed of a single device. However, the management device 1 may be realized by computing resources such as a plurality of processors and memories, such as a cloud computing system. In this case, each unit constituting the control unit 11 is realized by executing a program by at least one of a plurality of different processors.

The contact management unit 110 manages the contact information of the manager M of the vegetable production plant F and the contact information of the seedling consumer U supplied by the vegetable production plant F. The contact information of the administrator M and the contact information of the consumer U are information such as an e-mail address, a telephone number, and an address of the administrator M and the consumer U, respectively. A contact database (not shown) for storing these contacts is stored in the storage unit 10, and the contact management unit 110 manages the contact database.

The supply amount acquisition unit 111 acquires the supplyable amount of the seedlings of the vegetable production plant F at a specific time point determined before the seedlings are shipped. In the vegetable production plant F, for example, lettuce, salad vegetables, leafy vegetables such as arugula, and seedlings of herbs such as basil, sage, and mint are grown. It takes about a month from planting the seeds to making them edible. At the vegetable production site F, the seedlings grown for about two weeks after the seeds germinate are shipped to the receiving place B.

The "specific time point determined before the shipment of seedlings" is date and time information defined as the timing when the supply amount acquisition unit 111 acquires the shippable amount of seedlings (that is, the supplyable amount of seedlings), and the seeds are It is multiple date and time information defined between planting and shipping. The date and time information may be determined experimentally in consideration of the growth rate of seedlings, the demand forecast of seedlings, etc., but is, for example, midnight every night.

The degree of seedling growth is confirmed daily by the manager M or a professional worker, and is input to the manager terminal Tm. By acquiring the degree of growth of the seedlings from the manager terminal Tm, the supply amount acquisition unit 111 can acquire the shipable amount of the seedlings at that time and the estimated amount of the seedlings that can be shipped thereafter.

As described above, the supply amount acquisition unit 111 of the seedlings is based on the growth rate of the seedlings analyzed by image analysis technology using a growth status confirmation engine created by taking a picture of the seedlings with a camera or the like and using machine learning or the like. You may obtain the supplyable amount.

The usage status acquisition unit 112 acquires the usage status of the seedling growing device H owned by the seedling consumer U at a specific time point. The storage unit 10 stores information for the management device 1 to communicate with a plurality of seedling growing devices H having jurisdiction over the notification. The usage status acquisition unit 112 acquires the usage status from each of the plurality of seedling growing devices H whose management device 1 has jurisdiction over the notification via the network N.

The sensor O is, for example, an optical sensor and is arranged adjacent to each lot L. The sensor O detects whether or not seeds or seedlings are present in each lot L. All lots are not labeled because of the complexity, but the rectangle having the same shape as the rectangle with the symbol O in FIG. 3 is the sensor O. Each O is an IoT sensor, and the detected information can be transmitted to the management device 1 via the network N.

The demand amount acquisition unit 113 acquires a demand forecast amount which is an estimated value of the demand amount of the seedlings at a specific time point based on the usage status of the seedling growing device H. Specifically, the demand amount acquisition unit 113 predicts the demand for seedlings from the availability of lot L in each seedling growing device H. Further, based on the past vegetable seedling consumption history of the consumer U, the demand amount acquisition unit 113 can estimate that the lot is vacant at the time when the demand forecast should be made even if it is not vacant at the time of confirming the lot L. If it is L, the demand for seedlings may be reflected in the forecast. The past vegetable seedling consumption history of the consumer U can be obtained by associating the transition of the number of vacant lots acquired by the usage status acquisition unit 112 with each consumer U and storing it in the storage unit 10.

The divergence degree acquisition unit 114 acquires the divergence degree between the supplyable amount of seedlings acquired by the supply amount acquisition unit 111 and the demand forecast amount of the seedlings acquired by the demand amount acquisition unit 113. The notification unit 115 sends a notification corresponding to the degree of deviation acquired by the degree of deviation acquisition unit 114 from among a plurality of notifications determined according to the degree of deviation between the supplyable amount of seedlings and the predicted demand amount. And at least one of the contacts of the consumer U. The plurality of notifications determined according to the degree of divergence each describe an action for reducing the degree of divergence. As a result, the management device 1 according to the embodiment can reduce the discrepancy between the transferable number of seedlings grown in the vegetable production plant F and the demand number of seedlings by the consumer U.

FIG. 4 is a diagram schematically showing an action database 100 that stores actions executed by the notification unit 115 according to the embodiment according to the degree of deviation. In FIG. 4, the degree of deviation D between the supplyable amount of seedlings and the predicted demand amount is defined by the difference between the available supply amount of seedlings and the predicted demand amount of seedlings (that is, the degree of deviation D = available amount-demand forecast amount). Has been done. Therefore, when the degree of deviation D is a positive value, it indicates an excess supply, which is a state in which the supplyable amount is larger than the demand forecast amount. On the contrary, when the degree of deviation D is a negative value, it indicates an excess demand, which is a state in which the supplyable amount is smaller than the demand forecast amount.

When the supplyable amount with respect to the demand forecast amount of the seedlings is less than the first threshold Th1, that is, when the supplyable amount is smaller than the demand forecast amount of the seedlings, the notification unit 115 is in a state of excessive demand. Notify the estimated shipping date of the seedlings to the contact information. In addition, the notification unit 115 may notify the contact of the manager M of a message urging the growth of the seedlings to be accelerated when the supplyable amount with respect to the demand forecast amount of the seedlings is less than the first threshold value Th1.

Here, the “scheduled shipping date of seedlings” is the date on which it is estimated that the supplyable amount of seedlings will compete with the predicted demand amount of seedlings. By notifying the consumer U of the scheduled shipping date of the seedlings, the notification unit 115 can be expected to reduce the number of consumers U who visit the receiving place B before the scheduled shipping date. Further, the notification unit 115 encourages the manager M to promote the growth of seedlings, so that the supply amount of seedlings before the scheduled shipping date can be increased.

Further, the "first threshold value Th1" is a "threshold value for determining an action when there is an excessive demand" that the notification unit 115 refers to for determining whether or not to execute an action prepared for an excessive demand for seedlings. The specific value of the first threshold value Th1 may be determined by an experiment in consideration of the growth rate of seedlings, the take-back pattern of the consumer U, etc., and is, for example, −5% of the predicted demand amount. That is, when the degree of deviation D is a negative value and its absolute value exceeds 5% of the forecasted demand amount, the notification unit 115 notifies the contact information of the consumer U of the estimated shipping date of the seedlings, or the manager M. Send a message to promote the growth of seedlings.

5 (a)-(b) is a diagram schematically showing an example of a notification screen notified by the notification unit 115 according to the embodiment.

As shown in FIG. 5A, when the seedlings of coriander are in excessive demand, the notification unit 115 notifies the consumer U of the estimated shipping date together with the information of coriander. As a result, the number of consumers U who visit the receiving place B before the scheduled shipping date can be suppressed.

As shown in FIG. 5B, when the seedlings of salad vegetables are in excessive demand, the notification unit 115 specifically notifies the administrator M of the method of promoting the growth of the seedlings of salad vegetables. As a result, the manager M who receives the notification can quickly promote the growth of the salad vegetable seedlings.

When the supplyable amount with respect to the demand forecast amount of the seedlings exceeds the second threshold Th2, that is, when the supplyable amount is larger than the demand forecast amount of the seedlings, the notification unit 115 causes the consumer U. Notify the contact information of a message urging the seedlings to be picked up. Further, the notification unit 115 may notify the contact of the manager M of a message urging the growth of the seedlings to be delayed when the supplyable amount with respect to the demand forecast amount of the seedlings exceeds the second threshold Th2.

Here, the "second threshold value Th2" is a "threshold value for determining an oversupply action" that the notification unit 115 refers to for determining whether or not to execute an action prepared for an oversupply of seedlings. The specific value of the second threshold value Th2 may be determined by an experiment in consideration of the growth rate of seedlings, the take-back pattern of the consumer U, etc., and is, for example, + 5% of the predicted demand amount. That is, when the degree of deviation D is a positive value and its absolute value exceeds 5% of the demand forecast amount, the notification unit 115 notifies the contact information of the consumer U of the estimated shipping date of the seedlings, or the manager M. Send a message to slow the growth of seedlings.

6 (a)-(b) is a diagram schematically showing another example of the notification screen notified by the notification unit 115 according to the embodiment. Specifically, FIGS. 6 (a)-(b) are diagrams showing a notification screen notified by the notification unit 115 when the seedlings are oversupplied. These notification screens are also stored in the action database 100.

More specifically, FIG. 6A shows an example of a notification screen in which the notification unit 115 notifies the consumer U when the seedlings are oversupplied, and FIG. 6B shows the case where the seedlings are oversupplied. Shows an example of a notification screen in which the notification unit 115 notifies the administrator M. As shown in FIG. 6A, when the seedlings of salad vegetables are oversupplied, the notification unit 115 notifies the consumer U of a message prompting the consumer U to pick up the seedlings together with the information on the salad vegetables. As a result, the number of consumers U who visit the receiving place B can be increased.

As shown in FIG. 6B, when the basil seedlings are oversupplied, the notification unit 115 specifically notifies the manager M of the method of slowing the growth of the basil seedlings. As a result, the manager M who receives the notification can quickly take measures to slow down the growth of the basil seedlings.

The case where the demand amount acquisition unit 113 acquires the demand forecast amount of the seedlings based on the usage status of the seedling growing device H has been described above. The demand amount acquisition unit 113 may acquire the demand amount of seedlings based on the usage status of the seedling growing device H and the demand amount in the past at the same time as the forecast time. In order to realize this, the storage unit 10 includes a demand database for recording the fluctuation history of the demand amount of seedlings.

FIG. 7 is a diagram schematically showing a data structure of a demand database 101 that records a history of fluctuations in the amount of demand for seedlings in the past according to the embodiment. As shown in FIG. 7, the demand database 101 stores the monthly demand amount of each year for each type of seedling. FIG. 7 shows the history of monthly demand for salad vegetable seedlings from 2009 to 2016.

The demand amount acquisition unit 113 predicts the demand amount of seedlings based on the past demand amount at the same time as the specific time point acquired by referring to the demand database 101 and the usage status acquired by the usage status acquisition unit 112. To do.

For example, the demand amount acquisition unit 113 corrects the demand forecast amount downward if the past demand amount is smaller than the demand forecast amount acquired only from the usage status acquired by the usage status acquisition unit 112. On the contrary, the demand amount acquisition unit 113 corrects the demand forecast amount if the past demand amount is larger than the demand forecast amount acquired only from the usage status acquired by the usage status acquisition unit 112. In this way, the demand amount acquisition unit 113 can improve the accuracy of the demand forecast amount by increasing the basis for forecasting the demand forecast amount.
