Abstract

PROBLEM TO BE SOLVED: To reduce the costs of a reform provision service. SOLUTION: A reform request input part 12 inputs a reform request based on a list price system reform price standard gathered from many reform requesters. A reform execution request generation part 14 generates a through pass execution request based on a list price system execution price standard to an execution trader corresponding to the request and the request does not include estimations for the respective reform requests. The list price system reform price standard and the list price system execution price standard are set based on the convergence value of a reform execution cost when the number of execution items increases. The reform execution request generation part 14 generates execution requests for the number of an execution cost convergence range capable of obtaining the convergence of the reform execution cost to one execution trader. At the time, the instruction of a reform request distribution part 16 for distributing many reform requests to the plural execution traders is obeyed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for receiving a remodeling request from a remodeling client and instructing a contractor to perform the remodeling, and more particularly to a system capable of providing a low-cost remodeling service.

[0002]

2. Description of the Related Art As is well known, houses age with the passage of age. When a house becomes old, new construction and renovation (renovation) can be considered. Renovation has the advantage of lower costs compared to new construction. Also,
Remodeling like new construction is possible, and seismic reinforcement technology is also improving. However, conventional remodeling, although cheaper than new construction, is still quite expensive. In order to promote orders for renovation, it is necessary to increase the price difference with new construction.

FIG. 1 shows a conventional general order for remodeling. Upon receiving a request from a reform requester, an order receiving company such as a real estate company first designs and estimates a reform. The design and quotation are presented to the client, and the client and the ordering company make adjustments through a meeting to determine the renovation work. In response to this, the ordering company issues a construction request (construction request) with the design document and the quote to the construction company.

[0004]

Conventionally, an order-receiving company between a client and a contractor performs a remodeling design for each request, creates an estimate, and coordinates with the client. . The work of estimation and the like is a factor that raises the cost of providing the renovation.

[0005] In the case of a new construction, there is a case where costs such as estimation can be reduced by supplying a large number of houses having the same specifications. However, as for the renovation, since the base houses are different, it is necessary to create a dedicated design for each case and to make an estimate based on the design, which increases the renovation cost as described above.

The present invention has been made under the above background, and an object of the present invention is to provide a system capable of providing a remodeling service at a low price by greatly reducing or eliminating work such as estimation.

[0007]

In order to achieve the above object, the present invention adopts a fixed price system such as a unit price per tsubo for a renovation offer price to a renovation requester. In addition, a fixed price system will be adopted for the construction request price to the contractor. The adoption of the fixed price system can greatly reduce or abolish the work of creating an individual estimate or the like at the order receiving stage for each reform request.

[0008] However, one problem may arise in adopting a fixed price system for renovation. That is, since the homes on which the renovation is based are always different, the actual construction cost varies greatly, and the actual construction cost and the fixed-price construction request price cannot be balanced.

In order to avoid such a problem, according to the present invention, even if the construction cost of each case varies greatly, when the number of construction cases is increased, the construction costs are averaged and converged to a constant value. Pay attention to. Then, based on this convergence value, a construction request price at which the profit of the contractor is secured is set, and further, a reform offer price is set according to the construction request price. For each contractor, construction requests are generated in such a number that the convergence of the construction cost can be achieved. As a result, the problem of the fixed price system can be avoided, and work such as estimation is greatly reduced or abolished by adopting the fixed price system. As a result, a reform service can be provided at a low price.

Originally, unlike new construction, the cost of renovation differs greatly depending on the house on which it is based, so there was no idea to make the renovation a fixed price system. The present invention is not limited to such conventional ideas, and can use the convergence of construction costs to avoid problems associated with the fixed price system. Provide renovation services.

According to the present invention, there is provided a reform order support system and method which are useful for the above-mentioned regular price reform order.

One embodiment of the present invention is a reform order receiving support system. This support system is a renovation request collected from a number of renovation requesters, and is used to input information on renovation requests based on a fixed price remodeling price standard in which the renovation offer price per unit remodeling scale is fixed. And through-pass that does not include individual quotes for each remodeling request, based on the fixed-price construction price standard where the price of the renovation request per unit remodeling scale is fixed as a request to the contractor in response to the remodeling request A renovation request generation unit that generates an execution request, the renovation offer price per unit remodeling scale is set according to the execution request price per unit remodeling scale, and the installation per unit remodeling scale is performed. The requested price is a renovation when the number of works is increased Is set based on the convergence value for construction costs, the renovation construction request generation unit, to the one contractor, to produce a number of construction requirements construction costs convergence range convergence remodeling construction cost can be obtained.

Preferably, the system of the present invention includes a reform request distribution unit for distributing a large number of reform requests from a large number of reform requesters to a plurality of contractors. The large number of reform requests are distributed so that the number of construction requests within the construction cost convergence range is distributed to each of the contractors. INDUSTRIAL APPLICABILITY The system of the present invention is capable of distributing a number of construction requests within a construction cost convergence range to a plurality of construction contractors, and is useful for providing a fixed-price reform service.

Preferably, the reform request distribution unit presents a distribution state acquisition unit for acquiring a current reform request distribution state for each of the plurality of contractors, and the current reform request distribution state. And a contractor selection request unit for requesting selection of a contractor corresponding to the input reform request, and a contractor selection receiving unit for receiving selection of a contractor responding to the request of the contractor selection request unit. . The system of the present invention, by presenting the distribution status of the current renovation request, can encourage the distribution of the number of construction requests within the range of the convergence of the construction cost to each contractor, to provide a fixed-price reform service Available usefully.

[0015] In another aspect, the renovation request distribution unit includes a distribution state acquisition unit for acquiring a current renewal request distribution state for each of the plurality of contractors, and a renewal request distribution state based on the renovation request distribution state. A contractor determining unit that determines a contractor corresponding to the input remodeling request, the contractor determining unit ensures that each of the plurality of contractors has a construction request of the number of the construction cost convergence range. The contractor is determined according to the contractor determination criteria set to perform the contract. The system of the present invention is capable of distributing the number of construction requests within the convergence range of construction costs to each contractor by automatically determining the contractor according to the contractor determination criteria, and providing a fixed-price reform service. Can be usefully used.

Another preferred embodiment according to the present invention relates to a method for supporting a reform order. This support method is a renovation request collected from a number of renovation requesters, and the renovation request input that inputs information of the renovation request based on the fixed price remodeling price standard where the renovation offer price per unit remodeling scale is fixed Through-pass that does not include individual quotes for each remodeling request, based on fixed-price construction price standards where the price of the renovation request per unit remodeling scale is fixed as a construction request to the contractor in response to the step and the remodeling request A renovation construction request generation step of generating a construction request, the renovation offer price per unit remodeling scale is set according to the construction request price per unit remodeling scale, and the construction per unit remodeling scale is performed. The commission price will be Omu is set based on the convergence value of the construction costs, in the renovation construction request generating step, generating a number of construction requirements construction costs convergence range convergence remodeling construction cost can be obtained.

Preferably, the method for assisting in receiving a reform according to the present invention includes a remodeling request allocating step of allocating a number of remodeling requests from a number of remodeling clients to a plurality of contractors. The plurality of renovation requests are distributed to each of the plurality of contractors so that the number of construction requests within the construction cost convergence range is distributed.

[0018] Preferably, the renovation request distribution step presents a distribution state acquisition step of acquiring a current renovation request distribution state for each of the plurality of contractors, and presents the current renovation request distribution state. And a contractor selection requesting step of requesting selection of a contractor corresponding to the input reform request, and a contractor selection receiving step of receiving selection of a contractor responding to the request of the contractor selection request unit. .

In another aspect, the reform request distribution step includes a distribution state acquisition step of acquiring a current reform request distribution state for each of the plurality of contractors, and a modification request distribution state based on the reform request distribution state. A contractor determining step of determining a contractor corresponding to the input remodeling request, and in the contractor determining step, each of the plurality of contractors secures a construction request of the number of the construction cost convergence range. The contractor is determined according to the contractor determination criteria set to perform the contract. These method aspects also provide the same advantages as the apparatus aspects described above.

In the present invention, the renovation may be the whole or part of the house. In the present invention,
It is intended to eliminate the need for a special estimate for each house, but it is not intended to eliminate the need for quotes that are easily created based on the fixed-price reform standard. . That is, an estimate under such a fixed price system may be naturally made.

[0021]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows an overall outline of a reform providing service according to the present invention. A renovation ordering company 1 such as a real estate company has many renovation requesters 2
Collect renovation requests from. A fixed-price system is adopted for the renovation offer price for the renovation request, and the renovation offer price is calculated from a fixed-price reform price basis in which the renovation offer price per unit remodeling scale is fixed. In the present embodiment, “tsubo (3.3 square meters) is used as the unit remodeling scale. Therefore, the remodeling price standard based on the fixed price system is a price per tsubo (for example, 200,000 yen per tsubo).

The renovation ordering company 1 designates a contractor 3 that undertakes each reform request, and sends a construction request to the designated contractor 3. In the present embodiment, a fixed price system is also adopted for construction requests. That is, the construction request price is calculated in accordance with the fixed price construction price standard in which the construction request price per unit reform scale is fixed. For the construction request price, “tsubo” is used as the unit reform scale.

When receiving a remodeling request, the reordering company 1 does not perform any work such as exclusive design and estimation for the remodeling request. In this regard, in the case of the conventional remodeling service, the design and estimation according to the house to be remodeled and the necessary adjustments are performed by the ordering company. In the present invention, instead of adopting the price system, the conventional work such as dedicated design and estimation is abolished. The renovation ordering company 1 basically only specifies a contractor who undertakes a renovation request. The reform request is passed to the designated contractor as it is.

As described above, in the present invention, since the reform request is passed to the contractor as it is, the request for the contractor is referred to as a "through-pass request". As is evident from the above, the through-pass construction request does not include a design document or quote made by the renovation ordering company. Upon receiving the through-pass construction request, the contractor designs a reform and actually remodels the requested house in accordance with the design.

The main advantages of the fixed price system are design at the stage of receiving orders,
Cost reduction by reducing or eliminating estimation and related work. On the other hand, the price list has the following disadvantages. Unlike mass production new construction, renovation is based on existing homes. Since the houses to be renovated differ from one house to another, the actual construction cost (implementation cost) for renovation is always different. There is a possibility that the construction cost will not be equal to the construction request cost determined by the fixed price system. Due to these circumstances, it is considered that reforms that are handled on a case-by-case basis are not originally suitable for the fixed price system.

The present invention avoids the problem of adopting a fixed price system for renovation as follows.

In FIG. 3, the horizontal axis is the number of constructions,
The vertical axis is the average value of the execution cost per tsubo (the value obtained by dividing the total of the execution cost by the total number of tsubo of all the construction cases). The curve in the figure indicates the range in which the average value of the implementation costs can be taken.

When the number of executions is small, the range of the average value of the execution cost is wide. Therefore, there is a possibility that the contractor may lose under the fixed price system. However, when the number of executions increases, the range in which the average of the execution costs can be narrowed, and the execution costs converge. The convergence value of the construction cost is X in the figure.
Indicated by In the present invention, a range in which the range of the construction cost is equal to or less than a certain value (more than the number of construction cases Y) is referred to as a construction case convergence range.

Then, based on the convergence value X of the construction cost,
The unit price of the construction request price is set. Specifically, it is a value obtained by adding the profit required by the contractor to the convergence value X of the construction cost. Further, the unit price of the renovation offer price is determined according to the unit price of the construction request price. Specifically, costs (including advertising costs, etc.) required for collecting a renovation request and providing a stable supply to a contractor are added to the unit price of the construction request price. As a result, the unit price of the renovation offer price is set to, for example, 200,000 yen.

In providing the reform service,
Under the above-mentioned price setting, the reform ordering company 1 issues a construction request to each construction company in the number of construction cases in the convergence range (see FIG. 3). This makes it possible to provide an appropriate reform service even under a fixed price system. By reducing the pre-design work and the like of the ordering company, the renovation offer price can be significantly reduced.

FIG. 4 shows a remodeling order support system suitably used for the characteristic remodeling service of the present invention. The reform order support system 10
It is used for the reform order receiving company in FIG. The reform order support system 10 is used to input a reform request and output a construction request corresponding to the input request.

The remodeling order support system 10 includes:
The main configuration includes a reform request input unit 12, a reform construction request generation unit 14, and a reform request distribution unit 16.

The reform request is input to the reform request input section 12 using the input device 18. The reform request includes the name of the client, the address, the scale of the reform, and the like. The input device 18 is, for example, a keyboard. The operator
The user inputs a reform request obtained by a document, telephone, facsimile, or the like using a keyboard. Input device 18
May include a reading device such as a scanner. Further, the communication device may function as the input device 18 and receive a reform request by communication from outside. The reform request may be received from the branch of the order receiving company or directly from the client. As described above, in the present embodiment, a reform request is a request based on a fixed price reform price standard.

The input reform request is recorded in the reform request storage unit 20 and passed to the reform request distribution unit 16. The reform request storage unit 20
Together with the construction request recording section 24, a reform order database 26 is formed.

The renovation construction request generation unit 14 generates a through-pass construction request of the present invention as a construction request to a construction company. As described above, the through-pass construction request is a request based on the fixed price construction price standard, and a special design or estimate for each request is not attached.

The through-pass construction request is output using the output device 22. The output device 22 is, for example, a printer,
A through-pass construction request document is printed using a predetermined sheet. The output device 22 includes a display, and an operator may look at the display and manually create the construction request document. Further, the communication device may function as the output device 22, and may directly or indirectly send a through-pass construction request to the construction company by communication.

The contractor who undertakes each reform request among a plurality of contractors is determined by the reform request distribution unit 16 as described below. The reform construction request generation unit 14 generates a through-pass construction request to the determined contractor in accordance with the decision of the reform request distribution unit 16.

The information of a large number of reform requests input to the reform request input unit 12 is passed to the reform request distribution unit 16. Each time a remodeling request is input, a contractor who undertakes the remodeling request is designated by the remodeling request distribution unit 16. As a result, a large number of reform requests input sequentially are distributed to a plurality of contractors. At this time, according to the following configuration, the number of reform requests that fall within the construction cost convergence range of FIG.

The reform request distribution unit 16 includes a distribution state acquisition unit 32 and a contractor selection request unit 3 as its main components.
4, includes a contractor selection receiving unit 36 and a contractor information storage unit 38.

The distribution state acquisition unit 32 is provided with the construction request recording unit 2
Referring to the record of the construction request recorded in No. 4, the distribution state of the current reform request to each contractor is obtained. The contractor selection requesting unit 34 presents the distribution status of the reform request to the operator, and requests the operator to select a contractor to undertake the input reform request. The presentation of the distribution state and the selection request of the contractor are performed on the display.

FIG. 5 is an example of a screen showing the distribution state of a reform request. The distribution target number is a target number of construction requests to each contractor. The distribution target number is set to an appropriate number within the construction cost convergence range shown in FIG. Further, the target number of distributions may be set appropriately differently according to the scale of the contractor. The distribution target number is set in advance and stored in the contractor information storage unit 38. The contractor selection request unit 34 reads out the distribution target number of each contractor from the contractor information storage unit 38.

A target number for each appropriate period, for example, a target number for each month may be used. In this case, a target number of distributions is assigned to each month, and the total thereof is the target number of distributions.
Preferably, the target number is set differently for each month, taking into account general fluctuations in the number of renovation orders per year.

The distribution number result is the number of construction requests already issued to the contractor. This information is obtained by the distribution state acquisition unit 32 with reference to the construction request recording unit 24. The goal achievement is the degree of achievement of the target distribution, and here,
The ratio (%) of the actual distribution number to the target distribution number is used. The target achievement degree is calculated by the distribution state acquisition unit 32 or the contractor selection request unit 34.

Further, as shown in FIG. 5, the location and territory of the contractor are displayed on the screen in the distribution state. The territory is a regional area where the contractor undertakes construction, and is generally an appropriate area centered on the location of the contractor. These pieces of information are also read from the contractor information storage unit 38. If the number of contractors is large, only the contractor whose request target enters the territory may be displayed on the screen with reference to the reform request.

The distribution state shown in FIG. 5 is an example of the present invention. It goes without saying that a screen different from that in FIG. 5 may be used. What is necessary is just to show the distribution situation to each contractor. Preferably, the status of the distribution results with respect to the number of cases in the main construction cost convergence range is presented, such as the degree of achievement of the target.

Returning to FIG. 4, the operator selects a contractor to receive the reform request in response to the contractor's selection request. In the present embodiment, one of the selection companies shown on the screen of FIG. 5 is selected using the keyboard and the pointing device. The operator selects a contractor whose degree of achievement of the target is low and whose address of the reform request falls within the territory. This selection is received by the contractor's selection receiving unit 36 of the reform request distribution unit 16. Then, by this selection, the contractor who undertakes the reform request is determined.

The determined contractor is notified to the reform request generator 14 together with the information of the reform request. In response, the reform construction request generation unit 14
Generate a through-pass construction request.

FIG. 6 shows a remodeling order support system according to another embodiment. In the present embodiment, the configuration of the reform request distribution unit 40 is different from that of FIG. In the system of FIG. 2, the reform request distribution unit 16
Uses an inquiry to the operator to entrust the decision of the contractor to respond to the reform request to the operator. In the present embodiment, the reform request distribution unit 40 automatically determines a contractor. Other configurations are the same as those in FIG. 2, and the description of those configurations will be omitted.

The reform request distribution unit 40 includes a distribution state acquisition unit 42, a contractor determination unit 44, and a contractor information storage unit 46. The distribution state acquisition unit 42 refers to the information stored in the construction request recording unit 24, and acquires the current reform request distribution state for each of the plurality of contractors, that is, the number of construction request occurrences up to now. .

The contractor determination unit 44 is a distribution state acquisition unit 4
2 determines the contractor corresponding to the input reform request based on the acquired renovation request distribution state.
The contractor determining unit 44 determines the contractor according to the contractor determination criteria. The contractor determination criteria are stored in the contractor information storage unit 46, and are determined so that each contractor secures the above-mentioned construction request within the above-mentioned construction cost convergence range, as exemplified below.

FIG. 7 shows an example of the contractor determination criteria. The table of FIG. 7 is set for each of a plurality of contractors. In this example, the distribution target achievement degree and the territory of each contractor are used to determine the contractor. The distribution target achievement degree is the degree of achievement of the target distribution number, and here, the ratio (%) of the distribution actual number to the target distribution number is used. As described with reference to FIG. 5, the target distribution number is set to an appropriate number within the construction cost convergence range, that is, the minimum number Y or more. A smaller target number, such as monthly, may be used. The territory is a regional area where the contractor undertakes construction, and is generally an appropriate range centered on the location of the contractor.

As shown in FIG. 7, the distribution target achievement degree is divided into three ranks. Three types of territories are set corresponding to the three ranks. The standard territory corresponds to the A rank with the highest degree of achievement, the primary expanded territory corresponds to the second B rank, and the secondary expanded territory is set to the lowest C rank. Standard territory, primary expansion territory,
Territory increases in the order of secondary expansion territory.

When the renovation request is input, the contractor determining unit 44 determines each contractor based on the distribution target number indicated in the contractor determination standard and the distribution status information acquired by the distribution state acquiring unit 42. Is calculated, and a territory corresponding to the distribution target achievement is calculated. For example, referring to FIG. 7, when the degree of achievement of the distribution target of the contractor N belongs to rank B, the primary expansion territory is selected. Note that the target achievement degree may be calculated in advance by the distribution state acquisition unit 42.

The contractor determining unit 44 determines whether or not the address of the reform request is included in the territory of each contractor. Then, the contractor determining unit 44 selects a contractor having a territory including the address of the reform request, and determines the contractor as a contractor to undertake the reform request.

Since the territories of a plurality of contractors overlap, the address of the reform request may be included in the territories of the plurality of contractors. In this case, the contractor with the lowest degree of achievement of the target is selected.

As described above, in the present embodiment, the contractor determination criteria are set so that the renovation request is assigned preferentially to the contractor having a low degree of achievement of the target based on the construction cost convergence range shown in FIG. ing. As a result, it is possible to distribute a reform request so as to secure a construction request that falls within the construction cost convergence range for each contractor.

In particular, in the present embodiment, the territory of each contractor is changed according to the degree of achievement of the target, that is, the territory of the contractor whose degree of achievement is low is expanded. Increase in the number of construction requests to contractors is appropriately promoted. Each contractor works efficiently in a narrow territory while the target achievement level is high (relatively high compared to other contractors), and expands the territory when the target achievement level decreases, And such an advantage can be obtained by the automatic sorting process.

The criterion for determining the contractor in FIG. 7 is an example, and the present invention is not limited to this. For example, a parameter other than the ratio may be used as the target achievement degree. Also,
The rank of the goal achievement may not be three, and the territory may be continuously changed according to the goal achievement.
Further, the size of the territory does not need to be changed according to the degree of achievement of the target, and in this case, the advantages of the present embodiment can be partially obtained.

In the system shown in FIG. 7, the contractor is automatically determined. However, in this automatic processing, the system need not completely determine the contractor. For example, a contractor determined by the system may be presented to the operator, and confirmation of the operator may be requested. Such semi-automatic processing is also included in the automatic processing described with reference to FIG.

The preferred embodiment of the present invention has been described above. According to the present invention, a reform order receiving system and an order receiving method suitably used for a regular price reform service are provided, and in particular, it is possible to provide a technology capable of avoiding a problem of a fixed price system relating to variation in execution cost, and as a result,
The cost of renovation can be reduced by reducing the cost of designing and estimating the ordering company.

The system shown in FIG. 2 can prompt distribution of the number of construction requests within the range of convergence of construction costs to each contractor by presenting the distribution state of the current reform request, and provide a fixed price reform. It can be usefully used for service operation.

The system shown in FIG. 6 is capable of distributing the number of construction requests within the range of the convergence of the construction cost to each of the contractors by automatically determining the contractor in accordance with the contractor determination criteria. It can be usefully used for the operation of the reform providing service.

Further, in the system of FIG. 6, in the automatic determination of the contractor, the territory of the contractor is changed in accordance with the degree of achievement of the distribution target based on the convergence range of the construction cost, so that a more appropriate reform request is transmitted. Minutes are realized.

The present embodiment can of course be modified by those skilled in the art within the scope of the invention. For example, in the present embodiment, “tsubo” is used as the unit reform scale, but other units may be used. Further, the unit used for the reform offer price and the unit used for the construction request price may be different. The unit renovation scale is 1
The number may be large, such as the number of cases, several cases, or a predetermined area.

The object of the renovation according to the present invention may not be the whole house, but may be a part of the house. Also, it is appropriate to include seismic reinforcement in the renovation.
By reducing costs, seismic reinforcement can be provided under fixed price services.

In the remodeling request price standard,
A plurality of types of renovation offer prices per unit remodeling scale may be used. For example, a plurality of basic unit prices are set according to a plurality of reform grades. Accordingly, the construction request price per tsubo will be plural.

Also, according to the present invention, it has been explained that the creation of an estimate by the renovation ordering company is unnecessary. This means that it is not necessary to make an estimate based on a design according to the specifications of each house. It is a matter of course that an estimate can be made in accordance with the number of tsubo under the fixed price system.
