Description

The present invention relates to construction reservation systems, methods, and programs.

When performing gas work (gas appliance installation work, gas type switching work, plumbing work, etc.), the sales representative of the gas company visits the customer's house, interviews the customer, confirms the site, and then selects a contractor. And make a reservation. At this time, the sales person informs the contractor of the contents of the hearing from the customer and the precautions at the site. The person in charge of accepting reservations of the contractor confirms the reservation contents and the schedule of each person in charge of construction, and replies to the gas company whether or not to accept the reservation. In addition, the sales staff selects the contractor from the neighboring contractors who have a vacancy on the construction date and time zone desired by the customer, based on the construction content and the address of the customer's house. Furthermore, if there is a change in the content of the request such as the construction date or if the construction is canceled, the sales staff will notify the contractor each time.

Patent No. 5035048

However, unlike the construction staff who actually carry out the construction, the construction contractor's reservation receptionist who interacts with the sales staff at the construction reservation stage has a communication error or omission from the sales staff to the construction staff. , This may lead to troubles with customers and management associations. In addition, it is not efficient to complete the construction reservation if the sales staff and the construction staff do not communicate directly from the construction reservation stage, and the sales staff selects the construction staff from the reservation stage. , It is desirable to be able to communicate directly. Furthermore, the sales person cannot grasp the working condition at the site, and it cannot be said that there is no problem in terms of the management responsibility of the gas company.

"D410 to 412" and "Special Notes 1 to 3 Attached" d413 to 415, and "Quotation" d416 indicating an estimate for the contractor to be reserved can be stored. The details will be described below.

The reservation data d400 is transaction data input by a sales person of a gas company. "Customer ID" d401, "Constructor ID" d406, "Constructor ID" d407, and "Sales person ID" d408 are masters (customer master, contractor master, construction person master, and sales person). Master. Neither is shown) is associated with the data. The "construction content" d405 stores a code indicating the type of construction (for example, 1: gas appliance installation work, 2: gas type switching work, 3: piping work, 4: other). In the "call call required / not required" d409, a code (for example, 0: unnecessary, 1: required) indicating the necessity of a call back from the construction staff to the sales staff is stored. "Special notes 1 to 3" d410 to 412 are matters to be communicated from the sales staff to the construction staff, for example, precautions at the site (for example, the parking place of the car and the management association need to be explained in advance. , There is a fierce dog, etc.), the sales person inputs a free or fixed phrase via the sales person terminal 101, and stores it. "Special notes 1 to 3 attached" d413 to 415 include attachments to "special notes 1 to 3" d410 to 412 (for example, a peripheral image of a site or a car parking place), or an address indicating the storage place, respectively. Store. In the example of FIG. 4, it is shown that the special notes and their attached files can be stored three by three, but the number of data items can be increased or decreased as necessary, and the number of stored items can be increased or decreased. The “quotation” d416 stores a construction quotation file for the contractor created by the sales person, an address indicating the storage location thereof, and the like.

The work report data storage unit 131 stores data related to the work report of the work being carried out or carried out by the contractor. FIG. 5 is a diagram showing work report data d500.

The work report data d500 shows a "construction ID" d501 uniquely indicating the work being carried out or carried out, a "customer ID" d502 uniquely indicating the work customer, a scheduled work date, a start time, and an end time, respectively.

Person in charge ID "d508," Sales person ID "d509 uniquely indicating the sales person," Start time "d510 and" Start person ID "d511 indicating the time when the start registration of the construction was performed and the person in charge of construction, respectively. In addition, it is possible to store the "completion time" d512 and the "completion technician ID" d513 indicating the time when the completion registration of the construction was performed and the construction technician, respectively.

The work report data d500 is transaction data input by the construction reservation server 100 based on the associated reservation data d400 and the like. The “construction ID” d501 is, for example, a sequence number assigned each time a record of this data is created. The "customer ID" d502 to the "sales person ID" d509 are the same as the "customer ID" d401 to the "sales person ID" d408, respectively. The "start time" d510 and "starter ID" d511, and the "completion time" d512 and "completion manager ID" d513 are registered by the construction staff at the site via the construction staff terminal 102. The system date and time of the construction reservation server 100 and the login user ID of the person in charge of construction at the time of performing the above are stored.

The evaluation data storage unit 132 stores data related to the evaluation of the sales staff with respect to the construction staff who carried out the construction. FIG. 6 is a diagram showing evaluation data d600.

The evaluation data d600 includes a "construction ID" d601 that uniquely indicates the work carried out, a "construction content" d602 that indicates the type of the work that has been carried out, and a "constructor" that uniquely indicates the contractor and the person in charge of the work that have carried out the work. "ID" d603 and "Construction Technician ID" d604, "Sales Person ID" d605 that uniquely indicates the evaluated sales person, and "Evaluation result" d606 and "Comment" that indicate the evaluation result and its comment for the carried out construction, respectively. "D607 and the like can be stored.

The evaluation data d600 is transaction data input by a sales person of a gas company. The “construction ID” d601 to “sales representative ID” d605 are the same as the “construction ID” d501 and the “construction content” d506 to “sales representative ID” d509, respectively. The "evaluation result" d606 stores, for example, a code indicating an evaluation result for the work carried out (for example, 1: no problem, 2: problematic (solved), 3: problematic (unsolved)). Using such evaluation data d600, it is possible to support an inexperienced sales person or the like to select an appropriate construction person.

Next, the process of the flowchart of FIG. 3 will be described along the flow. FIG. 3 is a flowchart showing a process from construction reservation to evaluation registration according to an embodiment of the present invention. In this process, the sales person selects a construction person at the customer's house via the sales person terminal 101 and makes a construction reservation for the customer, and the construction person accepts the construction reservation via the construction person terminal 102. It is for answering. Further, in this process, the construction staff performs construction start and completion registration at the customer's house via the construction staff terminal 102, and the sales staff performs evaluation registration via the sales staff terminal 101.

First, the sales person of the gas company who received the construction request from the customer at the customer's house inputs the reservation data d400 for the construction reservation to the contractor via the sales person terminal 101 (step 300). More specifically, the sales person logs in to the construction reservation system (for example, a dedicated website) provided by the construction reservation server 100 via the sales person terminal 101, and lists the construction personnel of the construction contractor. Select a person in charge of construction from, and register data on customers and construction details. The construction technician can be selected by referring to the list of construction technicians. In the list of construction staff, the construction staff of the business establishment near the customer's house is displayed preferentially, the construction staff with good evaluation result is displayed preferentially using the evaluation data d600, and / or the construction with poor evaluation result is displayed. The person in charge can be hidden (it may be just grayed out so that the reason for hiding can be understood). The construction technician may register in advance the date and time when the reservation cannot be accepted via the construction technician terminal 102, and may not display it in the list of construction technicians or display it in gray out. In addition, the construction technician who already has a schedule on the reserved construction date and time can be hidden from the list of construction technicians or grayed out. Furthermore, the schedule of each construction staff on the construction day to be reserved can be displayed on the list of construction staff. As a result, the sales staff can select an appropriate construction staff. The entered reservation data is transmitted from the sales person terminal 101 to the construction reservation server 100 (step 301).

Next, the reservation reception processing unit 120 of the construction reservation server 100 receives the reservation data from the sales person terminal 101 (step 302) and stores it in the reservation data storage unit 130 (step 303). In another embodiment, only a specific construction technician (for example, a representative or a manager) of the construction technician is displayed on the list of construction technicians, and the representative who has accepted the reservation is the company's own company. It is also possible to select and assign a person in charge of construction. In this case, the sales person does not select the person in charge of construction who actually carries out the work from the list of person in charge of construction, but selects, for example, the representative of the construction company. On the reservation data d400, in addition to the "construction technician ID" d407, data items such as "construction representative" are provided to store the identifier of the representative of the construction company selected by the sales staff. After that, when the construction technician is selected by the representative, the identifier of the construction technician is stored in the "construction technician ID" d407.

Next, the reservation reception processing unit 120 transmits a reservation notification indicating that the reservation has been made to the construction staff terminal 102 (step 304). The reservation notification to the construction technician terminal 102 is, for example, transmitted to the e-mail address of the construction technician registered in advance in association with the "construction technician ID" d407.

Next, when the construction staff receives the reservation notification from the construction reservation server 100 via the construction staff terminal 102 (step 305), the construction staff logs in to the construction reservation system and inputs the reservation data d400 input by the sales staff. Confirm (step 306). After confirming the reservation data, the person in charge of construction registers the reception response as to whether or not to accept the construction reservation in the construction reservation system (step 307). More specifically, the construction technician registers the reception response with one click by simply confirming the reservation contents on the operation screen as shown in FIG. 7 and without inputting new data. The operation screen of FIG. 7 will be described in detail.

FIG. 7 is a diagram showing an operation screen 700 of the construction reservation system according to the embodiment of the present invention. The operation screen 700 is composed of a calendar unit 701, a reservation content unit 702, and a next operation unit 703. In the calendar unit 701, for example, a monthly calendar is displayed (calendar display can be switched by selecting any month), and the number of reservations for each date is displayed (for example, surrounded by a broken line). On the 22nd, it means that one reservation has been registered). Also, for example, if you click on the 22nd surrounded by a broken line (if multiple reservations are registered on the same day, you will be asked to select one from them), the reservation data for one reservation on that date will be reserved. It is displayed in the content unit 702. The reservation content section 702 displays the reservation data for the construction staff to confirm the reservation details, but if the reservation data cannot be displayed, the sales staff, the construction date and time, etc. are displayed as shown in FIG. Other data can be displayed by clicking the "Open Details" button. Also, by clicking the "phone" button displayed to the right of the sales person in the reservation details section 702, the call can be made to the mobile number of the sales person registered in advance in association with the "sales person ID" d408. You can also. Further, if a call back to the sales staff is required based on the "call call required" d409, the "phone" button may be highlighted to prompt the construction staff to call back. The next operation unit 703 displays a button for the next operation required by the construction technician. In the example of FIG. 7, the "construction start" button for the construction start registration is shown, but the construction reservation system displays a button on the next operation unit 703 based on the reservation data d400, the work report data d500, and the like. It can be switched. In addition to the "Construction start" button, there are "Construction acceptance" button for accepting construction reservations, "Construction refusal" button for rejecting construction reservations, and "Construction completion" button for registering construction completion. .. As a result, the construction staff can register the next operation such as starting construction with one click, and send a notification corresponding to each next operation to the sales staff based on the reservation data d400 associated with each button. ..

Further, in another embodiment described above (a form in which a sales person selects a representative of a construction company), the representative confirms the reservation data d400 and then, after confirming the reservation data d400, the representative is in charge of each construction from the list of the construction personnel of the company. You can check the schedule of the person and select the person in charge of construction to which the work will be assigned. The construction technician terminal 102 of the assigned construction technician is notified to that effect, and the construction technician confirms the reservation data d400 (step 306) and registers the reception response (step 307).

Returning to the flowchart of FIG. 3, when the construction staff registers the reception response via the construction staff terminal 102 (step 307), the reservation reception processing unit 120 receives the reception response (step 308), and the reception response is set to the reception response. Based on this, it is determined whether or not the construction reservation has been accepted (step 309).

The reception response received from the construction staff terminal 102 indicates that the construction reservation will be accepted, and when the construction reservation is completed, the process proceeds to the Yes route in step 309, and the reservation reception processing unit 120 notifies the sales staff terminal 101 of the reservation completion. Transmit (step 310). On the other hand, when the reception response indicates that the construction reservation is rejected, the process proceeds to the No route in step 309, and the reservation reception processing unit 120 transmits the reservation refusal notification to the sales person terminal 101 (step 311). Each notification to the sales person terminal 101 is transmitted to, for example, an e-mail address of the sales person registered in advance in association with the "sales person ID" d408. In addition, the sales person who received the reservation refusal notification selects another construction person from the list of the construction person, and starts over from step 300. In this case, the rejected construction technician may not be displayed in the list of construction technicians, or may be grayed out.

When the construction person who has received the construction reservation starts the construction, he / she registers the construction start at the site via the construction person terminal 102 and sends the construction start notification to the construction reservation server 100 (step 312). As described above, the construction start registration can be performed with one click on the operation screen as shown in FIG. 7.

Next, when the work report processing unit 121 of the construction reservation server 100 receives the construction start notification from the construction person terminal 102 (step 313), the work report data d500 is created based on the associated reservation data d400 or the like (step 313). Step 314), and the data is stored in the work report data storage unit 131 (step 315). It should be noted that the work report data may be created in advance, and here, only the "start time" d510 and the "start person in charge ID" d511 may be updated. The "start time" d510 and the "start person ID" d511 are updated by the system date and time of the construction reservation server 100 when the construction start notification is received, and the login user ID of the construction person who registered the construction start, respectively. .. Further, the work report processing unit 121 transmits a construction start notification to the sales person terminal 101 (step 316).

Next, when the construction is completed, the construction staff registers the construction completion at the site via the construction staff terminal 102, and sends the construction completion notification to the construction reservation server 100 (step 317). Construction completion registration can also be performed with one click on the operation screen as shown in FIG. 7.

Next, when the work report processing unit 121 receives the work completion notification from the work person terminal 102 (step 318), the work report data d500 stored in the work report data storage unit 131 is updated (step 319). To update the work report data at this time, the system date and time of the construction reservation server 100 when the "completion time" d512 and the "completion person ID" d513 each received the construction completion notification, and the construction for which the construction completion registration was performed. It is updated by the login user ID of the person in charge. Further, the work report processing unit 121 transmits a construction completion notification to the sales person terminal 101 (step 320).

Next, when the sales person receives the construction completion notification from the construction reservation server 100 via the sales person terminal 101 (step 321), the sales person inputs the evaluation data d600 for the construction person who performed the construction (step 322). ), Sent to the construction reservation server 100 (step 323).

Next, the evaluation registration processing unit 122 of the construction reservation server 100 receives the evaluation data from the sales person terminal 101 (step 324) and stores it in the evaluation data storage unit 132 (step 325). The evaluation data registered here is used when selecting a person in charge of construction, as described above. After step 325, this process ends.
