Embodiment 1.
FIG. 1 is a configuration diagram of an electronic commerce system according to the first embodiment.

The electronic commerce system 1 is a system for electronically trading elevators. Here, the elevator is an elevator that transports passengers by, for example, a car that goes up and down the hoistway. In the electronic commerce system 1, elevator transactions are carried out between consumers and suppliers. Consumers of elevators are, for example, designers of buildings in which elevators are installed. Elevator suppliers are, for example, manufacturers of elevator equipment applied to buildings.

In this example, the consumer designs the building by a BIM system (BIM: Building Information Modeling). The consumer designs using, for example, CAD software (CAD: Computer-Aided Design) corresponding to the BIM system. In the BIM system, the integrated BIM model, which is data including building information, is shared by a plurality of contractors involved in building design, for example. Here, the plurality of vendors includes, for example, a building designer and a manufacturer of individual equipment of a building such as an elevator. Building information contained in the integrated BIM model includes, for example, data on the three-dimensional shape of buildings and equipment, data on manufacturing specifications such as parts and materials of each part, data on performance such as weight, strength and function of each part. It also includes data on coordination between contractors such as construction time. In this respect, the construction of an integrated BIM model corresponds to, for example, the virtual construction of a building on the data. In a BIM system, it is possible to confirm the relevance and consistency of each part of a building, for example, based on an integrated BIM model.

The integrated BIM model is constructed, for example, by combining a plurality of BIM models. A BIM model is data of building elements added to a BIM system project. The plurality of BIM models include, for example, an architectural BIM model and an elevator BIM model. The building BIM model is data including information on the building itself, such as a structural material of the building. The elevator BIM model is data including information on the elevator.

The elevator BIM model contains information on multiple parameters about the elevator. The parameter is, for example, a numerical value, a boolean value, or a value selected from a plurality of items. Multiple parameters for the elevator include, for example, the model of the elevator, the speed of the car, the loading capacity of the car, the dimensions of each part, the electrical options, and the design specifications. The dimensions of each portion may be the width, depth, and height of the car, the spacing between the floors on which the car stops, and the spacing between the cars when multiple cars are provided. Some or all of the parameters are set to be changeable by the consumer in the BIM system.

The elevator BIM model includes constraint information about the parameters as metadata. Constraints on parameters include, for example, ranges for numerical parameters. The constraint condition for a parameter may be a condition between a plurality of parameters. The constraint condition for the parameter may include, for example, whether or not a combination is possible for a plurality of alternative parameters, a conditional expression for a plurality of numerical parameters, and the like. Constraints on elevator parameters may be, for example, a range of rated or maximum speeds of the car, a range of loading capacity, a range of fluctuations in power supply voltage, and the like. The constraint condition for the parameters of the elevator may be a condition between the structural material of the building and the like. The constraint on the parameters of the elevator may be, for example, a condition for ensuring a clearance between the wall surface of the hoistway or the structure arranged on the hoistway and the cage in the hoistway. Constraints may include restrictions based on laws and regulations related to elevators. The constraints may include constraints on the specifications of the elevator.

In the BIM system, it is possible to confirm whether the parameters satisfy the constraints based on the metadata included in the elevator BIM model. For example, the CAD software corresponding to the BIM system confirms whether the parameters satisfy the constraints when the consumer changes the parameters of the elevator BIM model. The parameter confirmation may be performed each time the parameter is changed. Alternatively, the parameter confirmation may be performed collectively after the plurality of parameters have been changed. Therefore, the consumer can change the parameters of the elevator BIM model according to the building so as to satisfy the constraint condition even if he / she does not have the expertise of the elevator. That is, if the consumer receives the elevator BIM model including the metadata from the elevator supplier or the like, the consumer can incorporate the elevator BIM model into the architectural BIM model to form an integrated BIM model. The consumer is provided with the elevator BIM model through the electronic commerce system 1.

In this example, for the same elevator, the supplier prepares two types of elevator BIM models, an elevator BIM model used by the supplier and an elevator BIM model provided to the consumer. The elevator BIM model used by the supplier is more detailed data than the elevator BIM model provided to the consumer so as to include sufficient information for manufacturing the elevator. The elevator BIM model used by the supplier may include non-public information such as know-how. The elevator BIM model used by the supplier is confidential data. The elevator BIM model provided to the consumer is lighter data than the elevator BIM model used by the supplier, in which information unnecessary for the consumer is reduced so that the communication load can be reduced. The elevator BIM model provided to consumers is publicly available data.

The consumer of the elevator uses the electronic commerce system 1 of the elevator by the terminal device 2. The terminal device 2 is an information terminal used by consumers of elevators.

The second communication unit 7 transmits the elevator BIM model to the first communication unit 4, for example, through a website of electronic commerce. The first communication unit 4 transmits inquiries data to the second communication unit 7 through, for example, an electronic commerce website. Inquiry data is data representing inquiries for elevator transactions. The inquiry data may include, for example, an order acceptance / rejection reply request, a quotation request, a drawing creation request, a manufacturing specification creation request, and the like. The inquiry data includes information on the parameters of the elevator BIM model. The inquiry data may include a set of parameters exported from the elevator BIM model or the elevator BIM model itself as parameter information.

The second communication unit 7 may be equipped with, for example, a mail server function. The first communication unit 4 may be equipped with a mail client function. In this case, the second communication unit 7 transmits the response data to the first communication unit 4 by e-mail, for example. The response data is data representing the response to the inquiry of the elevator transaction. The response data may include, for example, information such as an order acceptance / rejection response, a quotation, a drawing, or a manufacturing specification.

Each function of the server device 6, such as the second communication unit 7, the answer generation unit 8, the proposal generation unit 9, the interface unit 10, the storage unit 11, and the order processing unit 12, is installed in the server device 6, for example, in electronic commerce. It is executed based on the program.

Subsequently, an example of an elevator transaction by the electronic commerce system 1 will be described with reference to FIG.
FIG. 2 is a flow chart showing an example of the operation of the electronic commerce system 1 according to the first embodiment.

The consumer uses the terminal device 2 to access the website of electronic commerce. In step S11, the first communication unit 4 of the terminal device 2 requests the second communication unit 7 to download the elevator BIM model by the operation of the consumer. In step S21, the second communication unit 7 acquires the requested elevator BIM model from the consumer model DB 23. The second communication unit 7 transmits the acquired elevator BIM model to the first communication unit 4. In this way, the first communication unit 4 downloads the elevator BIM model. The operation of the server device 6 in step S21 is an example of the operation in the providing step.

Next, in step S12, the first BIM processing unit 5 changes the parameters of the elevator BIM model according to the design situation of the building by the operation of the consumer. Subsequently, in step S13, the first BIM processing unit 5 incorporates the elevator BIM model into the building BIM model to form an integrated BIM model by the operation of the consumer. Subsequently, in step S14, the first BIM processing unit 5 confirms whether or not the parameter satisfies the constraint condition based on the metadata included in the elevator BIM model when the parameter is changed by the operation of the consumer. The first BIM processing unit 5 displays a warning to, for example, a consumer when the parameter does not satisfy the constraint condition. Alternatively, the first BIM processing unit 5 may limit the storage of the integrated BIM model including the elevator BIM model whose parameters have been changed when the parameters do not satisfy the constraints. Steps S12 to S14 may be adjusted repeatedly as needed.

Next, in step S15, the first communication unit 4 uploads the changed elevator BIM model parameters to the server device 6 by the operation of the consumer. The first communication unit 4 uploads, for example, a file of a set of parameters exported from the elevator BIM model. The parameter set file is an example of inquiry data. Here, it has been confirmed by the consumer in the BIM system that the parameters included in the inquiry data satisfy the constraint conditions.

Next, in step S22, the second communication unit 7 receives the inquiry data. The second communication unit 7 assigns a unique reception number to the inquiry data. The parameter acquisition unit 15 of the answer generation unit 8 acquires parameters from the inquiry data. The answer generation unit 8 associates the acquired parameter with the reception number and stores it in the customer information DB 22. The operation of the server device 6 in step S22 is an example of the operation in the reception step.

Next, in step S23, the manufacturing specification generation unit 16 generates manufacturing specification data for manufacturing arrangements based on the parameters acquired by the parameter acquisition unit 15. The manufacturing specification data for manufacturing arrangements is manufacturing specification data including detailed information to the extent that an elevator can be manufactured. Manufacturing specification data for manufacturing arrangements includes, for example, a list of parts and materials arranged by the supplier, a list of processes performed by the supplier, and the like. The manufacturing specification generation unit 16 acquires the elevator BIM model corresponding to the acquired parameters from the supplier model DB 24. The manufacturing specification generation unit 16 sets the parameters of the acquired elevator BIM model according to the parameters acquired from the inquiry data. The manufacturing specification generation unit 16 acquires information on manufacturing specifications such as parts and processes corresponding to the set elevator BIM model from the manufacturing specification master DB 25. When the elevator BIM model includes BIM parts such as elevator parts, the manufacturing specification generation unit 16 may acquire information on the manufacturing specifications corresponding to the BIM parts from the manufacturing specification master DB 25. In this way, the manufacturing specification generation unit 16 generates manufacturing specification data for manufacturing arrangements. The manufacturing specification data may include information on the construction period. The manufacturing specification generation unit 16 stores the generated manufacturing specification data for manufacturing arrangement in the customer information DB 22 in association with the reception number of the inquiry data. The manufacturing specification generation unit 16 may generate manufacturing specification data for submission by omitting unnecessary information from the consumer from the manufacturing specification data for manufacturing arrangement.

Next, in step S24, the estimate generation unit 17 generates estimate data based on the parameters acquired by the parameter acquisition unit 15. The estimate generation unit 17 generates estimate data by referring to, for example, manufacturing specification data for manufacturing arrangements generated based on parameters. The estimate generation unit 17 acquires price information such as parts and processes included in the reference manufacturing specification data from the price master DB 26. The estimate generation unit 17 generates estimate data by integrating the acquired prices. The quotation generation unit 17 stores the generated quotation data in the customer information DB 22 in association with the reception number of the inquiry data.

Next, in step S25, the drawing generation unit 18 generates drawing data based on the parameters acquired by the parameter acquisition unit 15. The drawing generation unit 18 generates drawing data by processing of the BIM system in the second BIM processing unit 14, for example, based on the elevator BIM model in which the manufacturing specification generation unit 16 sets the parameters. The drawing generation unit 18 stores the generated drawing data in the customer information DB 22 in association with the reception number of the inquiry data.

Next, in step S26, the proposal generation unit 9 generates proposal data as follows, for example. The proposal generation unit 9 calculates the evaluation value of the elevator corresponding to the parameter based on, for example, the elevator BIM model in which the manufacturing specification generation unit 16 sets the parameter. The evaluation value may be, for example, an elevator price, a construction period, power consumption, or an estimated value of passenger transportation volume. When the evaluation value is a value calculated by the answer generation unit 8 such as the price or the construction period, the proposal generation unit 9 may acquire the evaluation value from the answer generation unit 8. The proposal generation unit 9 may calculate an evaluation value by combining a plurality of values. The proposal generation unit 9 stores the direction of improvement for the evaluation value. For example, when the evaluation value is a price, the direction in which the price decreases is the direction of improvement. For example, when the evaluation value is an estimated value of transportation volume, the direction in which the estimated value increases is the direction of improvement. The proposal generation unit 9 generates information on the changed parameters as proposal data when the evaluation value is improved by changing the parameters of the elevator BIM model, for example. Alternatively, the proposal generation unit 9 may generate the information of the elevator BIM model as the proposal data when, for example, there is an elevator BIM model of the elevator compatible with the elevator represented by the inquiry data. The proposal generation unit 9 may generate proposal data including a plurality of proposals. The proposal generation unit 9 stores the generated proposal data in the customer information DB 22 in association with the reception number of the inquiry data.

Next, in step S27, the response generation unit 8 collectively generates response data by collecting the data generated after the inquiry data is received. The response generation unit 8 generates response data by collecting, for example, manufacturing specification data for submission, estimation data, and drawing data. The second communication unit 7 transmits the generated response data to the first communication unit 4. The second communication unit 7 may transmit the proposal data generated by the proposal generation unit 9 to the first communication unit 4 together with the response data. The operation of the server device 6 in steps S23 to S27 is an example of the operation in the answer step.

Next, in step S16, the terminal device 2 displays the data received by the first communication unit 4 from the second communication unit 7. The consumer confirms the response to the inquiry by checking the displayed data. The consumer decides whether or not to order the elevator based on the contents of the answer. When the consumer decides to place an order for an elevator, he / she performs an ordering operation. The first communication unit 4 of the terminal device 2 transmits the ordering information to the second communication unit 7 by the ordering operation of the consumer. Here, the ordering information is information that can identify an inquiry such as a reception number of inquiry data. After that, the operation of the electronic commerce system 1 proceeds to step S28. On the other hand, when the consumer decides not to order the elevator, he / she returns to step S12 and adjusts the parameters of the elevator BIM model. At this time, the consumer may change the parameters by referring to the contents of the proposal data.

In step S28, the second communication unit 7 receives the order information transmitted from the first communication unit 4. Subsequently, in step S29, the second communication unit 7 transmits a manufacturing start instruction to the order processing unit 12. Subsequently, in step S30, the order processing unit 12 performs order processing. The order processing unit 12 generates sales report data as order processing. The order processing unit 12 stores the generated sales information data in the customer information DB 22 in association with the reception number. In addition, the order processing unit 12 acquires manufacturing specification data and drawing data for manufacturing arrangements associated with the reception number from the customer information DB 22. The order processing unit 12 transmits the income manufacturing specification data and drawing data to the manufacturing factory. After that, the processing of the elevator transaction in the electronic commerce system 1 is completed.

As described above, the electronic commerce system 1 according to the first embodiment includes a model storage unit 20, a second communication unit 7, and a response generation unit 8. The model storage unit 20 stores the elevator BIM model. The elevator BIM model contains parameters and constraint information about the parameters. The parameters can be changed by the consumer. The second communication unit 7 receives inquiries data from the consumer who has acquired the elevator BIM model stored in the model storage unit 20. Inquiry data includes information on parameters that satisfy the constraints. The answer generation unit 8 generates answer data based on the parameters included in the inquiry data received by the second communication unit 7. The response data is sent to the consumer as a response to the inquiry data.
Further, the electronic commerce method according to the first embodiment is a method in which the server device 6 on the supplier side connected from the terminal device 2 of the consumer executes the providing step, the receiving step, and the answering step. .. The provision step is a step of providing the elevator BIM model to the consumer. The reception step is a step of receiving inquiries data from a consumer who has been provided with the elevator BIM model in the provision step. The response step is a step of generating response data as a response to the inquiry data received in the reception step and transmitting the generated response data to the consumer. In the response step, response data is generated based on the parameters contained in the inquiry data.
Further, the electronic commerce program according to the first embodiment is a program in which a server device 6 on the supplier side connected from a terminal device 2 of a consumer executes a provision step, a reception step, and a response step. ..

In the manufacture of elevators and the like, elevators are required to be designed so as to satisfy constraints such as manufacturing, legal regulations, and specifications. Here, in the electronic commerce system 1, an elevator BIM model including information on constraint conditions is provided to a consumer. Therefore, the consumer can change the parameters of the elevator BIM model according to the building so as to satisfy the constraint condition even if he / she does not have the expertise of the elevator. Since the BIM system confirms that the parameters satisfy the constraint condition, the parameters included in the inquiry data transmitted from the consumer to the supplier satisfy the constraint condition of the elevator. Therefore, it is not necessary to have an interpersonal meeting in which a supplier with specialized knowledge participates in order to set the parameters of the elevator so as to satisfy the constraint condition. In addition, the response data automatically generated based on the parameters included in the inquiry data allows the consumer to determine whether or not to order the elevator. This makes it possible to order elevators without the need for interpersonal meetings between consumers and suppliers.

In addition, the response generation unit 8 generates data including information on manufacturing specifications, price quotations, and drawings as response data.

The elevator BIM model corresponds to a virtually manufactured elevator on the data. Therefore, a specific transaction document can be generated based on the elevator BIM model in which the parameters are set. As a result, the consumer can obtain the response data including the specific transaction document as a response to the inquiry data. Therefore, the consumer can order the elevator without the need for an interpersonal meeting to determine the detailed contents. In this example, the case where the answer generation unit 8 generates the data including the information of the manufacturing specification, the information of the price estimate, and the information of the drawing as the answer data has been described. Data including any one or more of the specification information, the price estimate information, and the drawing information may be generated as the response data.

Further, the electronic commerce system 1 includes a proposal generation unit 9. The proposal generation unit 9 generates proposal data based on the evaluation value. The evaluation value is calculated based on the parameters included in the inquiry data. Proposal data is data that represents a proposal to a consumer. The proposal data is transmitted to the consumer together with the response data.

As a result, the consumer can compare the elevator represented by the proposed data with the elevator set by himself / herself. This gives consumers the opportunity to order elevators that are more in line with their wishes. The electronic commerce system 1 does not have to include the proposal generation unit 9. The consumer can save the trouble of comparing the elevator set by himself / herself with other elevators.

Further, the proposal generation unit 9 generates, as the proposal data, data representing a proposal of a parameter different from the parameter included in the inquiry data.
Further, the proposal generation unit 9 generates data representing a proposal of an elevator BIM model different from the elevator BIM model acquired by the consumer as the proposal data.

The proposal data includes the proposal in a format that can be incorporated into the building BIM model as an elevator BIM model. Therefore, the consumer can easily compare the proposed elevator with the elevator set by himself / herself.

Further, the electronic commerce system 1 includes a transaction storage unit 19 and an order processing unit 12. The transaction storage unit 19 stores the information included in the response data. When the second communication unit 7 receives an order for the contents of the response data from the consumer who has received the response data, the order processing unit 12 processes the order based on the information stored in the transaction storage unit 19.

As a result, the manufacture of the elevator can be started promptly without the need for interpersonal meetings between the consumer and the supplier. Therefore, the lead time from ordering to delivery is shortened. In addition, costs related to interpersonal meetings are reduced.

The inquiry data may include request data. The request data is data including a request for the evaluation value used in the proposal of the proposal generation unit 9. The requirements for the evaluation value are, for example, an upper limit for the price of the elevator or a deadline for the construction period. The proposal generation unit 9 generates proposal data including the proposal when the proposal of the evaluation value satisfying the request can be generated by changing the parameter or the like. As a result, the consumer can obtain a more desired elevator proposal based on the request for the evaluation value.

In addition, the consumer may upload the inquiry data without changing the parameters when the acquired elevator BIM model can be incorporated into the building BIM model without changing the parameters.

In addition, the consumer does not have to operate the BIM system in the terminal device 2. The consumer may use the BIM system operating in the BIM server from, for example, the terminal device 2 through the network 3. Here, the BIM server is, for example, a server device or a virtual server operated by a business operator that provides a BIM system. At this time, the elevator BIM model may be provided to the consumer by transmission from the server device 6 to the BIM server, for example. In addition, the consumer sets the parameters of the elevator BIM model on the BIM server. In addition, the consumer confirms on the BIM server whether the set parameters satisfy the constraint conditions.

Further, the server device 6 does not have to have the model storage unit 20. At this time, the consumer may acquire the elevator BIM model from, for example, a database of the elevator BIM model provided by a business operator providing the BIM system or another business operator. Here, the elevator BIM model stored in the database is provided by, for example, an elevator supplier to a business operator operating the database. Alternatively, the consumer may acquire the elevator BIM model offline. The consumer may acquire the elevator BIM model from, for example, a storage medium distributed at an event such as an exhibition, or a storage medium attached to a catalog.
