Description

  The present invention relates to a residential building support system, and more particularly to an open, fair, seamless, and comprehensive residential building support system using the Internet.

  In the conventional housing construction method, a housing sales company conducts sales activities such as having a salesperson visit each home to acquire customers (constructors), and new housing for newspapers, televisions, and other advertising media. In order to raise customers' willingness to purchase by seeing actual properties and attracting customers, we are operating and maintaining model houses in residential exhibition halls.

After acquiring suitable customers by these means, the home sales company will consider the housing to be purchased by the customer, taking into account the land conditions of the housing to be built, the customer's financial situation, the customer's preference for the housing style, etc. Conduct business talks.
If the negotiations with the customer are gathered to some extent, the designer (architectural design shop) designs the house to be purchased, determines the building materials to be used, and calculates the total according to the customer's intention.

After building contracts with customers including loans from financial institutions, construction of actual houses is started. In the construction of a house, the construction material selected by the building design shop is purchased by a construction contractor from a delivery manufacturer (building material dealer), and the house is built using this building material. .
Orders, deliveries, and built-in constructions are made to interior manufacturers as construction progresses.

When the construction of the house is completed, the customer's confirmation is obtained, and the customer is paid by the customer through a predetermined bank or the like, and various insurance contracts are made with the insurance company in parallel.
Completion, maintenance and renovation after moving in are usually carried out by a customer through a home sales company or its contract agent in the same manner or in a simplified manner.

As described above, a plurality of companies are usually involved in housing sales, and exchange of documents and drawings related to housing construction work between related companies is performed by methods such as telephone, fax, interview, and mail.
Building materials required for housing construction are sold through manufacturing companies, trading companies, wholesalers, dealers, and construction companies.
Construction work undertaken by the main contractor is disassembled and executed by contractors such as subcontractors and grandchild contractors.
In addition, the exchange of funds between related companies is performed through a plurality of financial institutions such as banks.

Such conventional housing construction methods have the following unsolved problems.
(1) When building a plan for a house that the customer wants to build according to his / her funds, land conditions and preferences, the customer needs to do it through a sales person who is generally not necessarily knowledgeable about the house of the housing sales company. It took.
In addition, home sales companies need to attach sales staff to customers and provide various materials in response to customer consultations, which is troublesome.

  (2) In order to acquire customers, home sales companies will need to pay for newspaper advertisements, construction of housing exhibition facilities, individual visits by sales staff, etc., as described above, which ultimately increases the cost of housing construction. There was a problem.

  (3) Building materials are purchased through a distribution process involving multiple delivery manufacturers such as manufacturing companies, trading companies, wholesalers, dealers, etc. In addition, for housing construction, subcontracting by multiple contractors, Since it is carried out through forms such as subcontracting, there is a problem that the cost of the house to be built eventually increases and the construction period is also long.

  (4) Furthermore, in the distribution process of building materials, the sales price at each distribution stage is unclear, and the contract prices of contractors such as subcontractors, grandchild contractors, great-grandchild contractors, etc. are uncertain. There was a problem of rebounding to the cost.

  (5) In addition, the materials and construction methods of the house are determined by the design of the architectural design shop, and these are added up based on the past construction performance data, but the past data is opaque as described above. However, there is a problem that the cost of the housing is also increased because the estimation is time-consuming and more generally the estimation is performed on the safety side.

  (6) Furthermore, since the communication between companies related to the construction of houses is done by mail of documents, drawings, interviews, faxes, etc. as described above, even if confidentiality is ensured, it is troublesome. It took a long time, and there were still many uncertainties for customers.

  (7) It is not impossible for franchise companies, mainly home sales companies, to reduce material costs through mass purchases and mass sales, but as a result, designs that neglect the individuality of customers are more likely to occur. There was a problem that standardized building materials were supplied, making it difficult for customers to be satisfied housing.

  (8) Also, since maintenance of homes after sales is entrusted to each contract agent, it is not always safe to take measures in the event of an emergency, for example, if there is a problem with the home such as water leakage or leakage. There was no problem.

In order to solve these problems, for example, Patent Document 1 discloses the exchange of information and funds settlement by digitizing, visualizing and performing on the Internet, from customer plan construction to occupancy, that is, customer budget, preference. Electronic information that allows the design of houses according to the conditions of the land to be freely performed, reduces the extra costs of the housing sales company, and simplifies and transparentizes the materials and construction process. A method for contracting and constructing a house is disclosed.
JP 2002-063231 A

However, such construction methods have significant problems.
First, the choice of the related vendors (from the above designers to insurance companies and maintenance contract agents) is virtually at the discretion of the home sales company, guaranteeing free competition between related vendors in the same business. It has not been.

  Second, the choice of relevant vendors, especially the combination of customer-salesperson and customer-designer, where the quality of the relationship is critically dependent on the customer's outcome satisfaction, effectively considers the compatibility of the two. Without being mechanically determined.

  Therefore, the present invention further utilizes the Internet and the digitization of information on it to open not only to potential / explicit customers but also to all potential / explicit affiliates. The purpose is to provide a home building support system that provides free and low-cost competition by providing fair use opportunities, and has an environment that enables optimum construction for customers as a whole.

  In particular, it aims to provide a housing construction support system that enables the selection of salespersons and designers who are compatible with customers so that the customer-salesperson and customer-designer relationships are optimal. .

  In order to achieve the above object, the invention described in claim 1 includes a support center having a server CPU, a plurality of information storage devices, and a plurality of terminals for customers, and a plurality of IP-types formed on the Internet. A CIG (Closed-Interest-Group) network comprising a VPN (Internet Protocol Virtual Private Network) is provided, and each of the plurality of CIGs includes at least a CIG in which a producer, a designer, a contractor, and a delivery maker are registered. , At least the following step: the support system performs the customer's personality evaluation for the customer, step a, the designer registered after performing the personality evaluation in advance via the corresponding CIG network And solicited, and compatibility test Step c, selected by the customer via the step C, publicly solicited via the CIG network corresponding to the contractor, and determined by a successful bid, step d, publicly solicited via the CIG network corresponding to the material manufacturer , Functioning according to a flowchart including step e, determined by a successful bid.

  Further, as shown in claim 2, the producer registered after performing personality evaluation is solicited through the corresponding CIG network, and further selected by the customer through the compatibility test, step b , Including.

  Further, as shown in claim 3, the method further includes a step f of performing a psychological evaluation based on a questionnaire regarding an intention related to the customer's home building independently or in combination with the customer's personality evaluation. And

According to a fourth aspect of the present invention, in at least one of the steps a, b, and c, the personality evaluation and the compatibility test are performed by an MBTI (Myers-Briggs Type Indicator) method.
According to a fifth aspect of the present invention, the method further includes a step g of listening to an opinion of another designer who meets a condition designated by the customer with respect to a design result by the designer.

  According to the residential building support system according to claim 1, all information is digitized, and contractors related to residential construction are registered in the CIG network on the Internet for each industry group. Registered contractors are fair to each other. Since bidding can be given with limited information, a fair competitive environment is given to all the traders, and the optimum result for the customer as a whole is given.

As an industry group, not only contractors and delivery manufacturers, but also at least producers (sales representatives of home sales companies) and designers, it is seamless (consistent) and efficient for customers from design to completion. A residential building support environment can be provided.
In addition, by organizing real estate agents, financial institutions, and insurance companies into similar CIG networks, a more completely seamless and efficient housing construction support environment can be provided.

  According to the residential building support system according to claims 1 to 3, the customer's own intention and personality can be read more accurately, and for the producer and designer, the compatibility with the customer is a selection condition. The customer's true final intent can be determined early, allowing producers and designers, and thus all affiliates, to operate efficiently, minimizing redesign and restructuring, reducing costs, and And the satisfaction of all related companies.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an overall configuration diagram of a residential building support system according to a first embodiment.
This system includes first to eighth networks (hereinafter abbreviated as N / W) 41 to 48 formed via the support center 1 and the Internet 3.

  The support center includes a server CPU 10, common information storage devices 20 a to 28 a, individual information storage devices 20 b to 28 b, and a plurality of customer terminals 11 connected to the server CPU via dedicated interfaces or LAN lines, respectively. 11 is included. The server CPU 10 is connected to the Internet 3 via a Web server (not shown) if necessary.

  When the owners (hereinafter referred to as customers) 2 and 2 who want to build a house register with this system, they receive assistance from the staff of the support center through the terminal 11 of the support center 1 and exchange information, Proceed with construction.

The 1st to 8th N / W 41-48 are each configured on the Internet as a secure IP-VPN (Internet Protocol Private Network), each corresponding to 8 types of groups related to housing construction To do.
That is, each of 41 to 48 includes first to eighth types of traders: producer 31, designer 32, real estate company 33, construction company 34, delivery maker 35, interior maker 36, financial institution 37, and insurance company 38. However, if you register with this system, you can connect as many as you like.

The support center 1 may include a plurality of branches of various forms that are separated from each other. In this case, the customer terminal 11 provided in the branch is connected to an appropriate local server (not shown) and a second terminal. 9 is connected to the server CPU via IP-VPN N / W (not shown).
By providing a password to each registered customer, customer information is protected.

  In addition, the registered customer can access the support system using the password from any terminal connected to the Internet such as the customer's own PC as well as the customer terminal 11.

  The common information storage device 20a stores information (support service information, etc.) common to the registered customer 2, while the common information storage devices 21a to 28a store the types of business of the first to eighth types of traders, respectively. Common information (such as support service information) is stored.

  Individual information regarding the registered customer 2 is stored in the individual information storage device 20b, while individual information regarding the registered traders 31 to 38 of the first to eighth types is stored in the individual information storage devices 21b to 28b, respectively. Information is stored.

These information are encrypted and kept confidential, and the 1st to 8th and 9th N / Ws are allowed to circulate only within the scope contracted at the time of registration. A closed interest group (CIG) that can access only limited information to each other fairly is formed, and bidding and the like in the group described later is performed quickly and fairly.
As an encryption method, (for example) 128-bit ISS (Internet Security System) encryption using PKI (Public Key Infrastructure) is used.

  As a result, this system provides efficient and seamless (consistent) support for housing construction from design to construction and maintenance for customer 2, and is open and fair for related businesses 31-38. As a result, free competition is realized and the maximum satisfaction is achieved at the lowest cost as a whole.

FIG. 2 is a flowchart of the residential building support system according to the first embodiment as viewed from the viewpoint of the customer 2.
All information regarding the registered customer is stored in the information storage device 20b each time it is obtained or determined at each of the stages S0 to S40 described below.

In FIG. 2, at stage S0, the flow of the system itself for the customer is explained and the customer is registered.
In stage S1, the customer accesses customer support service information stored in the information storage device 20a, and through Q & A, a plurality of design candidates are presented to the customer, and the customer's intention is in which environment and which type. A rough estimate of whether it is in a house is made.

  In stage S2, a questionnaire for customer 2 is conducted, and the customer's psychological evaluation is made based on the result of the customer himself / herself writing in the questionnaire, and the customer's psychological more accurate customer intention that is not necessarily expressed verbally A survey is made and psychological indicators are obtained. [Step f]

  In stage S3, according to the results of stages S1 and S2, or further, personality evaluation of customer 2 is performed and personality classification (a personality index is assigned) [step a], and a candidate of producer 31 that seems to be compatible with the customer is selected. A customer is selected through the first N / W 41 and a customer selects one of the bid candidates [Step b], and the selected producer 31 replaces the sales representative of the conventional home sales company with the customer. We will continue to provide consistent support.

  Note that the producer 31 does not necessarily need to register / publicly recruit when selecting the compatibility with the customer from among the designers 32 registered as described later. It may be substituted in consideration of compatibility, in which case it is called “concierge”.

As the personality index classification and compatibility selection method of the customer 2, for example, a compatibility table based on an MBTI (Myers-Briggs Type Indicator) test as shown in FIG. 3 is used.
It is assumed that the producer 31 has also received a personality evaluation test at the time of registration and is given a personality index.

As shown in FIG. 3, according to the MBTI method, the personality of a person is generally classified into 16 types of ENFJ to ISTP, and a person having a personality index of the type indicated by the arrow is considered to have good compatibility.
The 16 types of ENFJ to ISTP consist of combinations of four types of alleles, E vs. I, N vs. S, F vs. T, J vs. P. For example, alleles E and I are “extroverted” and “introverted” Means. Detailed description is omitted here.
In addition, this figure may be changed in consideration of elements peculiar to residential construction.

Information relating to the producer 31 is encrypted and stored in the information storage device 21b every time after registration at the following stages.
On the other hand, support service information for the producer is stored in the information storage device 21a. When the registered producer accesses through the first N / W 41, the latest industry news, market information, and products are obtained through Q & A. Information can be obtained nationwide and can be used for marketing as a producer.

  Hereinafter, although not repeated individually, the information storage devices 22a to 28a are similarly used for the designer 32 to the insurance company 38 through the second to eighth N / Ws 42 to 48, respectively.

  In stage S4, the producer 31 grasps the true intention and request of the customer 2 and allows the customer to determine the construction method.

In stage S5, it is determined whether the construction method is “semi-custom” or “full custom”.
In the case of semi-custom, in stage S15, one model is selected on the customer terminal 11, the details of options are presented to the model, and customer 2 seems to be most suitable for his intention from among the options. Go to stage S16.

  The stage S15 will be described more specifically. When presenting a model, not only a still image such as a plan view and an elevation view, but also 3D computer graphics (3D-CG) software is used for the customer's 2 site / household. A three-dimensional dynamic image is displayed on the screen of the customer terminal 11 in accordance with the movement of the viewpoint accompanying the movement in the room.

  Digitized plan view / elevation data of each model is stored in the information storage device 20a in advance, and is sent to the terminal 11 in response to a request from the terminal 11 to display a plan view / elevation view, respectively. 3D-CG is rendered (rendered) and displayed (rasterized).

  This function can also be used in the above-described stage S1. In this case, for the standard model, 3D-CG drawing data is stored in the information storage device 20a in advance, and the customer terminal 11 displays the 3D-CG. It is also possible to increase system efficiency by simply performing

The displayed image can be changed on the spot each time using a pointing device such as a mouse to move the viewpoint, change the direction of the line of sight, change the dimensions such as the floor plan, change the material of the interior, etc. (On-the-spot), it is easy to present options and compare between options.
Furthermore, it is also possible to execute and display on-the-spot changes of these models and the estimated cost changes associated with the selection / change of options.

  With these 3D-CG moving image display and online editing functions, the producer 31 and the customer 2 can further communicate with each other, and the customer's request and true intention can be quickly confirmed on the spot.

  In the case of full custom, the designer 32 goes through the second N / W 42 in the stage S7 in the same procedure as in the case of the producer 31, that is, the designer 32 that seems to be compatible with the customer. Candidates are recruited via the first N / W 41, and the customer selects one of the bid candidates [step c]. (It is assumed that the designer 32 is also classified upon receiving a personality evaluation test such as MBTI at the time of registration.)

In stage S8, the selected designer 32 performs a custom design in accordance with the intention of the customer 2,
In stage S9, the design results are explained to the customer,
In stage S10, the customer's request is accepted, the process returns to stage S8, the design is corrected, the customer's agreement is obtained, and the process goes to stage S16.

  In this full custom design, even when the design by the designer is handwritten, the above-mentioned 3D-CG display and on-the-spot change display can be performed by making the handwritten design drawing into a digitized plan view / elevation view.

  In stage S16, the cost is estimated by the support center 1 based on the final design at that time and presented to the customer 2 in both cases of semi-custom and full-custom.

If customer 2 is not satisfied with the estimation results, the process returns to stage S4 and the design is modified until the customer's agreement is obtained,
When the customer's agreement is obtained, a contract between the support center 1 and the customer 2 is made in stage S18.

  The contract result is developed by the support center 1, and when the contract content includes real estate treatment such as land, old house, etc., that part is developed first, and the real estate agent 33 through the third N / W 43. The successful bidder is determined from among the vendors that have been released to the public.

  Next, the construction main body part of the contract contents is released to the construction contractor 34 and the material supplier 35 via the fourth and fifth N / W 44 and 45, respectively, and the successful bidder is determined from the bidders. [Step d, Step e].

  When the contents of the contract include interior (interior), fund financing, and property / life insurance, the interior maker 36, the financial institution 37, and the insurance company 38 through the sixth to eighth N / Ws 46 to 48, respectively. The successful bidder is determined from among the vendors that have been released to the public.

In the stage S30, based on the above, the construction work is started and intermediate checked based on the process chart prepared by the support center and managed by the producer 31, and is completed.
In the case where the contract content includes after-following, after-completion and tenant-after-following is performed by the support center or the producer 31 in stage S40.

  In this way, the selection of all the vendors 31 to 38 is performed openly and fairly with respect to the registered vendors, the adverse effects of multiple subcontracts are eliminated, and the information in each group is encrypted to obtain an IP-VPN. Therefore, the present system makes it possible to select the optimum for the customer 2 and to reliably execute the contract.

In the present embodiment, in the first embodiment, the flow corresponding to the part from the registration of the customer 2 to the completion of the design through the selection of the designer 32 in the case of full custom, and the corresponding information storage device database (hereinafter referred to as DB) The structure of (abbreviated) is presented in detail.
That is, these correspond to the flow relating to the stages S0, S2, S7, S8, S9 in FIG. 2 of the first embodiment and the structure relating mainly to the information storage devices 20b, 22b in FIG.

  FIG. 4 mainly shows the DB structure of the individual information storage device 20b for the customer and the individual information storage device 22b for the designer. The individual information storage device 20b for the customer further includes DB1 (customer DB) and DB2 (competition DB) is provided, and the designer individual information storage device 22b is provided with a designer DB (DB3).

As shown in FIG. 4, each of DB1, DB2, and DB3 includes a plurality of tables (hereinafter abbreviated as T), T10 to T13 (login T, basic T, request management T, contact T), T21 to T25 (basic). T, land T, desired land T, condition T, condition match T), T30 to T39 (login T, basic T, experience T, work T, contact T, prospective member T), and each table (T) As illustrated in the figure, it further comprises a number of items.
FIG. 8 shows detailed specific examples of items for each of these tables.

Furthermore, tables T41 (psychological evaluation T), T42 (personality evaluation T), and T43 (compatibility T) are configured, and are provided in the common information storage device 20a for customers, for example.
A detailed specific example of items in the psychological evaluation table T41 is shown in FIG. As the personality evaluation table T42, for example, the MBTI personality classification test table (not shown) in the first embodiment is used, and in this case, the compatibility table T43 is the same as in the first embodiment, and FIG.

5, FIG. 6, and FIG. 7 are connected in this order, and show a flowchart of the present embodiment.
In this flowchart, the stage is shown in the first column, the act of the designer is shown in the second column, the act of the support center is shown in the fourth column, and the table (T) belonging to DB3 (designer DB) is shown in the second column. The table (T) belonging to DB1 (customer DB) and DB2 (competition DB) is shown in the fourth column, and finally the customer's actions are shown in the fifth column.
The order of actions is indicated by white arrows, and writing / reading to the DB by actions is indicated by black arrows.
If the order of actions is clear by writing to and reading from the same table, white arrows between actions are omitted.

  In the stage “designer expected registration”, the support center collects information on the designers located in each area in advance and creates a prospective member T.

  In the next stage “customer registration”, as a result of explanation (not shown) of the flow of this system performed by the support center in the first step, when the customer applies for registration, the support center immediately enters the basic T ( T11) is opened and a customer ID and login T are created (set) and given to the customer.

  In the next step, the customer creates (fills in) an item (see T11 in FIG. 8) below the “zip code” of T11 and takes a personality classification test using the personality evaluation T (T42). Determine and fill in "indicators" (this test is not mandatory). [The above two steps correspond to stage S0 in FIG. 2 in the first embodiment.]

  If it is determined that the customer wants a full custom design (corresponding to stage S5 in FIG. 2), in the next step, the support center opens the basic T (T21) in the competition DB and sets the competition ID. The item below "desired date" (see T21 in FIG. 8, hereinafter, the annotation referring to this FIG. 8 is omitted) is entered. (Since the setting of the corresponding ID when the new table is opened is obvious in the figure, the description and illustration as the “act” of the support center are omitted in the following description.)

In the next step, if the customer has already taken care of the land, if the customer wants the “building type” or lower of the land T (T22), including the land allowance, to the support center Fill in the items below the “site area” of land T (T23).
In the next step, the customer fills in items under “lifestyle” in condition T (T24).
[The above three steps are also included in the stage S0 in FIG. 2 in the first embodiment.]

  In the last step, a psychological evaluation test is performed using a questionnaire-type psychological evaluation T (T41), and a “psychological index” is entered in T24 based on the customer's reaction (this test is not compulsory). [This step corresponds to stage S2 in FIG. 2 in the first embodiment.]

  In the next stage “Designer candidate determination / ordering”, the “Affiliation area” of the prospective member of the designer is read from T39, and the “Available area” of the registered designer is read from T31 and compared with the customer's residence area read from T11. Then, the designer candidate is determined, transmitted to the determined designer candidate, and bidding is started.

If a designer who intends to bid is already registered, the process goes directly to the next stage, “Designer bid and best candidate decision”.
If the designer who intends to bid is not registered, in the next stage "Designer Registration", when the designer applies for registration, the support center immediately opens the basic T (T31) in the designer DB and creates the designer ID and login T. (Set) and give to the designer.

The designer fills in items below “E-mail address” of T31 (basic T), and uses the personality evaluation T (T42) to determine and fill his / her “personality index” through a personality classification test.
Next, if you enter an item under “floor area” of T32 (experience T) and an item under “work name” of T33 (work T), the support center deletes the designer from T3) (probable member T). To complete registration.

In the next stage “Designer Bidding and Determination of Optimal Candidate”, the bidding designer writes the intention of bidding in T34 (Contact T).
The support center transfers “contact T” to the customer and at the same time updates the “competition flag” of T12 (request management T), and each item of T31 (basic T) and T32 (work T) for each designer who bids. Compare the content of each item with the content of each item of T21 (Basic T), T22 (Land T), and T24 (Condition T) in the Competition DB, calculate the “Condition of Condition”, and the designer / customer Both personality indexes are compared to calculate a “compatibility matching degree”, and these are entered in T25 (condition match T).
By browsing the customer T25, for example, a maximum of three designers are determined as optimum candidates.

In the next stage “designer candidate nomination”, the “competition flag” of T12 (request management T) related to the optimal candidate is updated, and the contents of T11 (basic T) and T22 (land T) are updated if necessary. Enter “Design Request” in (Contact T).
[The above four stages of “designer candidate determination / ordering”, “designer registration”, “designer bid and optimum candidate determination”, and “designer candidate nomination” are combined and correspond to stage S7 in FIG. 2 in the first embodiment.]

In the next stage “work design”, the designated designer enters “acceptance” in T34 (contact T), starts work design, and fills in the “progress” on T34 as needed to complete the work design. Then, the design result is entered in T33 (work T).
These “acceptance”, “progress status” and “work design completion” are updated for “competition flag”, “progress status” and “progress status” in T12 (request management T), and are added to the customer's browsing. The customer views the work (design result).

In the next stage “Listening to Professional Opinions”, customers can select professionals who want to listen to opinions on works obtained from the designer by specifying search conditions. [Step g]
That is, the support center searches and compares T31 (basic T) and T32 (experience T) of the designer DB based on the search condition, selects a suitable professional, and the customer goes to T13 (contact T) addressed to the professional. Fill in the “Request for Opinion”.

  The nominated professional creates an “opinion” and fills it in T34 (contact T), and at the same time writes corrections / improvements in the “comment” of T33 (work T). This process is T12 (request management T). At the same time, it is recorded on the customer's browsing.

In the next stage, “Recruitment non-recruitment decision”, the customer considers including the opinions of professionals obtained in this way, and in some cases, asks the designer to modify the design, and adopts the final design result. Decide the rejection and notify the support system and the designer through this.
In the case of non-recruitment, for example, the design request can be repeated for the three optimal candidates.
[The above three stages of “work design”, “professional hearing”, and “non-recruitment decision” are combined and correspond to stage S8 in FIG. 2 in the first embodiment.]

  As described above, in the present embodiment, details of the subsystems related to the negotiation between the customer, the designer, and both of the entire systems disclosed in the first embodiment have been presented. Similar or similar subsystems can be configured for each of 33-38 and for negotiations between the merchant and the customer.
