[0019] FIG. 2 is a diagram schematically showing the configuration of the shipping management device 11. The shipping management device 11 includes a data processing unit 31, a data storage unit 32, and a communication unit 33. The data processing unit 31 is configured to include a processor such as a CPU. The data storage unit 32 is configured to include an HDD, an SSD, a semiconductor memory, or the like. The communication unit 33 is configured to include a communication module corresponding to the communication standard of the communication network 15. The data storage unit 32 stores inventory information 41, storage information 42, building information 43, and diagnostic information 44.

[0020] FIG. 3 is a diagram schematically showing an example of inventory information 41. The inventory information 41 is a database including items of a manufacturer ID, a product ID, an inventory quantity, and a test result. The inventory information 41 may include other items. The manufacturer ID is identification information for identifying a manufacturing manufacturer of building materials. The product ID is identification information for identifying building materials as products. The inventory quantity indicates the quantity of building materials stored in the warehouse 14. The test result indicates the result of a test performed on the building materials stored in the warehouse 14 by each manufacturing manufacturer. The test is, for example, a diffusion rate test by a small chamber method. Each manufacturing manufacturer obtains a plurality of test results for each building material by performing tests on each building material on a plurality of days. The test result includes the diffusion rate [μg / (m 2 ·h)] of VOC of the building material and the number of days after manufacture of the building material at the time when the test is performed, and corresponds to substance diffusion information indicating the diffusion rate of VOC from the building material. Based on these information received from the management terminals 13A to 13C, the data processing unit 31 creates the inventory information 41 and stores it in the data storage unit 32. The data processing unit 31 updates the inventory information 41 in real time or periodically at a fixed time every day.

[0021] FIG. 4 is a diagram schematically showing an example of storage information 42. The storage information 42 is a database including items of a manufacturer ID, ventilation equipment, ventilation rate, air conditioning equipment, storage temperature, and storage humidity. The storage information 42 may include other items. The ventilation equipment indicates the presence or absence of ventilation equipment in the warehouse 14 of each manufacturing manufacturer. The ventilation rate indicates the ratio [times / h] of the ventilation volume [m 3 per unit time by the ventilation equipment to the volume [m 3 of the warehouse 14 for the warehouse 14 having ventilation equipment. The air conditioning equipment indicates the presence or absence of air conditioning equipment in the warehouse 14 of each manufacturing manufacturer. The storage temperature indicates the set temperature [°C] of the interior of the warehouse 14 for the warehouse 14 having air conditioning equipment. The storage humidity indicates the set humidity [%] of the interior of the warehouse 14 for the warehouse 14 having air conditioning equipment. Based on these information received from the management terminals 13A to 13C, the data processing unit 31 creates the storage information 42 and stores it in the data storage unit 32.

[0022] FIG. 5 is a diagram schematically showing an example of the building information 43. The building information 43 is a database including items such as a housing ID, a scheduled delivery date, a scheduled occupancy date, a product ID, a required quantity, a construction area, and a scheduled shipment date. The building information 43 may include other items. The housing ID is identification information for identifying a house ordered by a user who will be an occupant. The scheduled delivery date is the date scheduled to deliver the house whose construction has been completed to the user. The scheduled occupancy date is the date scheduled for the user to occupy the delivered house. The product ID is identification information for identifying building materials used for the construction of the house. The required quantity indicates the quantity of building materials required for the construction of the house. The construction area indicates the construction area of the building materials in the house. The scheduled shipment date is the date scheduled to ship the building materials from the warehouse 14 corresponding to the construction date using the building materials. At the business office or showroom of the housing manufacturer, etc., the operator 20 obtains the information necessary in the negotiation with the user who is the orderer 21 and inputs it into the order terminal 12. The data processing unit 31 creates the building information 43 based on the information received from the order terminal 12 and stores it in the data storage unit 32.

[0023] FIG. 6 is a diagram schematically showing an example of the diagnostic information 44. The diagnostic information 44 is a database including a housing ID and items of each person scheduled to move into the house (in this example, the father, mother, and eldest son). The diagnostic information 44 may include other items. The items of the persons scheduled to move in indicate the sensitivity to VOC for each person scheduled to move in. The sensitivity is represented by a score with a maximum of 100 points, and the higher the score, the more sensitive to VOC. At the business office or showroom of the housing manufacturer, etc., the operator 20 conducts a sensitivity diagnosis for VOC for each person scheduled to move in and inputs the diagnosis result into the order terminal 12. The sensitivity diagnosis may use a known diagnosis method such as a diagnosis using a questionnaire of QEESI (Quick Environment Exposure Sensitivity Inventory), a diagnosis using a questionnaire of EESI (The Environmental Exposure and Sensitivity Inventory) by Miller and Prihoda, or a diagnosis using a questionnaire of MM040EA by Andersson. The data processing unit 31 creates the diagnostic information 44 based on the information received from the order terminal 12 and stores it in the data storage unit 32.

[0024] FIG. 7 is a flowchart showing the process executed by the data processing unit 31.

[0025] First, in step SP11, the data processing unit 31 acquires it by reading the inventory information 41 from the data storage unit 32.

[0026] Next, in step SP12, the data processing unit 31 acquires it by reading the storage information 42 from the data storage unit 32.

[0027] Next, in step SP13, the data processing unit 31 acquires it by reading the building information 43 from the data storage unit 32.

[0028] Next, in step SP14, the data processing unit 31 acquires it by reading the diagnostic information 44 from the data storage unit 32.

[0029] Next, in step SP15, the data processing unit 31 determines whether the sensitivity of the occupant (prospective occupant) to VOC is equal to or higher than a predetermined threshold based on the diagnostic information 44. When there are a plurality of occupants, the data processing unit 31 determines whether the highest sensitivity of the occupants is equal to or higher than the threshold.

[0030] When the sensitivity is equal to or higher than the threshold (step SP15: YES), next, in step SP16, the data processing unit 31 extracts substance emission information corresponding to the test result for the product ID to be ordered based on the inventory information 41. The data processing unit 31 calculates the decay characteristic 50 of the emission rate over time based on the plurality of emission rates and the plurality of days after manufacture included in the extracted substance emission information.

[0031] FIG. 8 is a diagram schematically showing an example of the decay characteristic 50. In this example, the data processing unit 31 performs calculations such as power approximation using the three measured values of the emission rates corresponding to 1 day, 3 days, and 7 days after manufacture, thereby calculating the non-linear decay characteristic 50 regarding the building material of the product ID to be ordered. For example, when the product ID to be ordered is "E01" in the example shown in FIG. 3, the data processing unit 31 calculates the decay characteristic 50 for each of the building material with the manufacturer ID "M01" and the product ID "E01" and the building material with the manufacturer ID "M02" and the product ID "E01".

[0032] In calculating the attenuation characteristic 50, the data processing unit 31 may correct the attenuation characteristic 50 based on the storage information 42. The VOC emission rate from building materials increases as the ventilation rate is higher, the storage temperature is higher, or the storage humidity is higher. The data processing unit 31 corrects the attenuation characteristic 50 based on the differences between the ventilation rate, storage temperature, and storage humidity for each of the warehouses 14A to 14C and the ventilation rate (0.5 times / h), storage temperature (28 °C), and storage humidity (50%) defined by the small chamber method, so that the storage conditions are standardized or normalized for all of the warehouses 14A to 14C. Note that known methods such as the Inoue method or the Berge method may be used for correction based on temperature, humidity, or temperature and humidity.

[0033] When the attenuation characteristic 50 is represented by a power approximation curve, the emission rate Y is defined by the following formula using the coefficients α, β and the attenuation days X corresponding to the scheduled date K.

[0034] Y = αX -β

[0035] The data processing unit 31 calculates the values of the coefficients α, β based on a plurality of emission rates and a plurality of days after manufacturing included in the extracted substance emission information. Further, the data processing unit 31 corrects the attenuation days X based on the differences between the ventilation rate, storage temperature, and storage humidity for each of the warehouses 14A to 14C and the ventilation rate, storage temperature, and storage humidity defined by the small chamber method.

[0036] Next, in step SP17, the data processing unit 31 estimates the emission rate at the scheduled date K of the building materials to be ordered based on the attenuation characteristic 50 calculated in step SP16 and the scheduled date information included in the building information 43. The scheduled date K is the scheduled shipment date, scheduled delivery date, or scheduled occupancy date.

[0037] Next, in step SP18, the data processing unit 31 determines whether there is a building material whose emission rate on the scheduled date K is equal to or lower than the allowable value for the VOC of the occupant. The allowable value is a value obtained by multiplying a general reference value (for example, the reference value determined by the VOC Emission Rate Standardization Research Committee for building materials) by a coefficient value of, for example, 0.5. The coefficient value may be changed according to the sensitivity of the occupant. For example, the higher the sensitivity, the smaller the coefficient value is set below 0.5, and the lower the sensitivity, the larger the coefficient value is set above 0.5. Also, the coefficient value may be changed according to the construction area of the building material. For example, the larger the construction area, the smaller the coefficient value is set below 0.5, and the smaller the construction area, the larger the coefficient value is set above 0.5.

[0038] If there is a building material whose emission rate on the scheduled date K is equal to or lower than the allowable value (step SP18: YES), the data processing unit 31 selects the building material as a building material to be used for the construction of the house and executes an ordering process.

[0039] If there is no building material whose emission rate on the scheduled date K is equal to or lower than the allowable value (step SP18: NO), the data processing unit 31 calculates the shortest scheduled date at which the emission rate becomes equal to or lower than the allowable value based on the attenuation characteristic 50, and notifies the operator 20 and the orderer 21 by transmitting the shortest scheduled date and the building material to the order terminal 12.

[0040] If the sensitivity is less than the threshold value (step SP15: NO), next, in step SP19, the data processing unit 31 selects a building material to be used for the construction of the house by a normal arrangement that does not consider the emission rate, and executes an ordering process. In the normal arrangement, the data processing unit 31 selects, for example, the building material of the manufacturer with the largest stock quantity.

[0041] According to the present embodiment, the data processing unit 31 selects a building material to be used for the construction of a building such as a house from among a plurality of building materials stored in the warehouse 14 based on the inventory information 41, the building information 43, and the diagnostic information 44. Thereby, the building material to be used for the construction of the building can be appropriately selected according to the sensitivity of the occupant to chemical substances.

[0042] Further, according to the present embodiment, the data processing unit 31 estimates the diffusion rate on the scheduled date K (scheduled shipment date, scheduled delivery date, or scheduled occupancy date) based on the attenuation characteristics 50 and the scheduled date information. Thereby, building materials with a diffusion rate equal to or lower than the allowable value on the scheduled date K can be appropriately selected.

[0043] Also, according to the present embodiment, the data processing unit 31 corrects the attenuation characteristics 50 based on at least one of the ventilation rate, storage temperature, and storage humidity in the warehouse 14. Thereby, the estimation accuracy of the diffusion rate on the scheduled date K can be improved.
