Detailed Description
The embodiment of the application discloses a project cost management system based on big data. Referring to fig. 1, a big data-based project cost management system includes an acquisition module 1, a retrieval module 6, a template storage module 5, and a cost result library module 7. The template storage module 5 is used for storing basic templates of various engineering project types. The engineering project types comprise construction engineering projects, water conservancy engineering projects, municipal engineering projects, road engineering projects and communication engineering projects. The basic template comprises project characteristics of project items corresponding to the project item types and needing price estimation during investment estimation, such as labor cost, planning fee, tax, enterprise management fee and the like of common workers in the construction project; and for example, the cost of water conservancy construction workers, the crane leasing cost, the enterprise management cost and the like in the water conservancy project. The template storage module 5 may be a relational database, such as MYSQL; it may also be a non-relational database, such as HBase.
The obtaining module 1 is used for obtaining the project type of the project to be estimated. Wherein, the project to be estimated means that a cost engineer needs to estimate the investment of the project to generate the project with the estimated price.
The calling module 6 is used for obtaining the project type of the project to be estimated from the obtaining module 1, and calling and outputting the corresponding basic template in the template storage module 5 according to the project type of the project to be estimated. The engineering cost management system in the embodiment is based on a computer processing system, and the basic template is output to a virtual desktop of a computer after being called by the calling module 6 for a costing engineer to obtain and use. The retrieval module 6 may also send the retrieved basic template to the cost engineer directly by way of mailing. If the basic template is sent to the cost engineer by using a mail sending mode, the basic template can be realized by a mail editor or a program with the functions of editing and sending the mail. After the construction engineer acquires the basic template input by the calling module 6, project features needing to be evaluated are added to the basic template according to the actual situation of the project to be evaluated on the basis of the project features contained in the basic template. Project characteristics that need to be evaluated are different for different project types, for example, assuming that the project type of the project to be evaluated is a construction project of a concrete structure, a cost engineer should estimate the cost of concrete, and thus should add the project characteristics of the cost of concrete to the foundation formwork. For another example, if the project type of the project to be estimated is a hydraulic project and the project to be estimated needs to use a concrete pipe, a cost engineer needs to add the project characteristic of the cost of the concrete pipe to the foundation template. And the cost engineer adds all the project characteristics thought by the cost engineer into the basic template to form the estimation template.
In order to facilitate a costist to add project characteristics, project characteristics needing to be evaluated are not easy to omit, and the cost achievement library module 7 is used for storing cost achievement data of engineering projects of various engineering project types. The project items stored in the cost result library module 7 are all project items that have been approved for construction, so the cost result data includes an investment estimation list of the corresponding project item, and the investment estimation list includes a plurality of project characteristics of the corresponding project item on which price estimation is performed in an investment estimation stage. The cost result library module 7 may be a relational database, such as MYSQL; it may also be a non-relational database, such as HBase.
The calling module 6 is used for calling and outputting cost achievement data of the same project type as the project to be estimated in the cost achievement base module 7 according to the project type of the project to be estimated. Like the basic template, the calling module 6 can output the called cost achievement data to a virtual desktop of a computer, and can also send the cost achievement data to a cost engineer through a mail.
After inputting the project type of the project to be estimated into the project cost management system, the cost engineer obtains the corresponding basic template and cost achievement data containing a plurality of project characteristics. And the construction engineer adds project characteristics required to be evaluated for the project to be evaluated into the basic template by referring to the project characteristics in the construction achievement data. The method is convenient for reducing the workload of the cost engineer, saves the time of the cost engineer, has certain prompting function on cost result data, and ensures that the cost engineer is not easy to omit project characteristics, thereby being beneficial to improving the accuracy of estimation results.
Referring to fig. 1, the cost achievement library module 7 is electrically connected with an updating module 8, and the updating module 8 is used for retrieving cost achievement data of the engineering project of which the distance between the completion time of the engineering project and the current time is less than 100 days through the internet. The updating module 8 is further configured to transmit the retrieved cost result data and the corresponding type of the engineering project to the cost result library module 7.
The project completion time refers to a time for completion acceptance of the project or a project completion time recorded in the construction cost achievement data of the project. The update module 8 may be a program or software that has the ability to retrieve certain preset fields over the internet and to identify preset features in the retrieved data. The preset field may be a field that enables the update module 8 to retrieve an engineering cost order for an already completed engineering project, for example a preset field that is an engineering cost list for an as built construction project. The preset characteristics comprise engineering project types and investment estimation lists. The update module 8 searches the retrieved project cost list for both the project item type and the investment estimate list, and if there are both fields in the project cost list and the completion time recorded in the project cost list is less than 100 days from the current time, the update module 8 transmits the project cost list to the cost result library module 7. And the cost result library module 7 stores the data transmitted by the updating module 8.
In order to facilitate the updating module 8 to accurately find the cost result data, a specific website address can be set, so that the updating module 8 only searches in the website address.
The updating module 8 is also used for deleting the cost achievement data of the engineering project with the distance between the completion time of the engineering project in the cost achievement library module 7 and the current time being more than three years from the cost achievement library module 7.
Referring to fig. 2, the construction engineer adds the project characteristics that the construction engineer wants to estimate to the basic template, and inputs the estimated template to the construction cost management system after the basic template forms the estimated template. Specifically, the costing engineer may input the estimation template through a human-computer interface, transmit the estimation template to a corresponding computer through a storage medium such as a usb disk, or transmit the estimation template to the computer through software such as a mail or a WeChat. The acquisition module 1 is used for acquiring an estimation template of a construction engineer aiming at the project to be estimated.
The project cost management system based on big data further comprises a rechecker contact information database module 2, a message processing module 3 and a to-do module 4. The contact information database module 2 is used for storing names of a plurality of review persons and contact information corresponding to the names. That is, the name of each of the reviewers in the reviewer contact information database module 2 corresponds to at least one contact information of the reviewer. The contact means may be a cell phone number, a micro signal code, a mailbox number and/or a QQ number. The reexamers in the reexamer contact mode database module 2 are classified according to the types of the engineering projects, namely, the names of the reexamers in charge of reexamining the building engineering projects and the corresponding contact modes are stored together, the names of the reexamers in charge of reexaming the hydraulic engineering projects and the corresponding contact modes are stored together, and the like. It should be noted that the same reviewer may be responsible for reviewing engineering projects of multiple engineering project types.
The rechecker comprises a plurality of primary cost operators who have less than three years of time for engineering cost work, on one hand, the salary of the primary cost operators is low compared with the salary of the cost operators who have more than three years of engineering cost work experience, and even if a plurality of primary cost operators are engaged, the investment cost is not increased excessively. On the other hand, although the primary construction cost engineer has no abundant construction cost processing experience, the primary construction cost engineer has a certain construction cost foundation, is high in enthusiasm and active in thinking, and is convenient to find and estimate the missing project characteristics in the template. The reviewer contact database module 2 may be a relational database, such as MYSQL; it may also be a non-relational database, such as HBase.
And the message processing module 3 is used for acquiring the estimation templates from the acquisition module 1, acquiring the contact information of a plurality of reexamers from the reexamer contact information database module 2, and respectively sending the estimation templates to the corresponding reexamers. The message processing module 3 is further configured to obtain the project type of the project to be estimated from the obtaining module 1, and obtain the contact information of a plurality of review personnel corresponding to the project type from the review personnel contact information database module 2 according to the project type of the project to be estimated. And then the estimation templates are respectively sent to corresponding reexamers.
For example, if the project to be estimated is a construction project, the message processing module 3 sends the estimation template to the reviewer in the reviewer contact information database module 2 who is responsible for reviewing the construction project. Specifically, in order to facilitate the message processing module 3 to distinguish the engineering project type corresponding to the responsibility of the reviewer in the reviewer contact information database module 2, a serial number or a name of the engineering project type may be added to the reviewer contact information database module 2. In addition, the message processing module 3 may be a set of programs and/or software that calls the evaluation template, determines the type of project in which the review personnel are located, calls the contact information of the review personnel, and sends the evaluation template to the corresponding review personnel in the form of mail or message.
After receiving the estimation template sent by the message processing module 3, the rechecker checks the item features in the estimation template, and fills a supplementary suggestion on the estimation template no matter whether the item features are omitted or not. For example, the item-free feature omission can be filled when the item-free feature omission does not exist; when item features are missing, XXXX which is not included in the estimation template can be filled in to be evaluated. And after the rechecker fills the supplement suggestions, feeding the estimation template with the supplement suggestions back to the engineering cost management system according to the original form. For example, the evaluation template received by the reviewer in the form of a mail is sent to the original mail account in the form of a mail. The message processing module 3 is used for receiving the estimation template with the supplementary suggestion fed back by the reexamination staff.
Referring to fig. 2, the to-do module 4 is configured to obtain the estimation template with the supplementary suggestion from the message processing module 3 and store the estimation template with the supplementary suggestion. The to-do module 4 may be a database or software having a storage function. The construction cost master obtains the estimation templates fed back by each reexampier from the module to be dealt with 4, and supplements the estimation templates according to the supplement suggestions on the estimation templates so as to avoid missing the project characteristics needing to be evaluated, thereby being beneficial to improving the accuracy of the estimation results.
Referring to fig. 2, the to-do module 4 is connected to a timing module 41 for timing the storage of the estimation templates stored in the to-do module 4. That is, when the to-do module 4 receives the estimation template with the supplement suggestion, the timing module 41 starts timing. The timing module 41 is connected with an alarm module 42, and a time threshold is set in the timing module 41. When the timing module 41 times out a time threshold for storage of an estimated template with a supplemental suggestion, an alarm instruction is transmitted to the alarm module 42. The alarm module 42 is used for receiving an alarm instruction and giving an alarm to a corresponding construction engineer after receiving the alarm instruction. The alarm mode can be short message and/or call notification. To remind the costist to process the estimation template with the supplementary suggestion in time.
The time threshold may be set according to the urgency of the project to be evaluated, and if the project to be evaluated is urgent, the time threshold is set to be shorter, for example, 12 hours. But may be longer, for example 48 hours. The timing module 41 may be a program or software having identification data or identification files and having functions of timing and transmitting an alarm instruction. The alarm module 42 may be an information editor or information editing software, and is capable of editing a short message or a mail when receiving an alarm instruction, and sending the short message or the mail to a designated mobile phone number or a designated mailbox number.
The implementation principle of the engineering cost management system based on big data in the embodiment of the application is as follows: the construction engineer inputs the project type of the project to be estimated into the project early management system, the project type is acquired by the acquisition module 1, the calling module 6 calls the project type from the acquisition module 1, the corresponding basic template is called from the template storage module 5, and the corresponding construction cost achievement data is called from the construction cost achievement library module 7. The calling module 6 outputs the called basic template and the cost achievement data, the cost engineer derives the basic template and the cost achievement data, and according to the actual situation of the project to be estimated, the project features which are not on the basic template but need to be estimated are added to the basic template, or some project features on the basic template can be deleted. When the cost engineer fills in the project characteristics, the data in the cost achievement data is referred for filling, and the project characteristics are not easy to omit.
And forming an estimation template after the construction engineer does not add the project characteristics thought by the construction engineer into the basic template. The estimation template is input into the project cost management system, the acquisition module 1 acquires the estimation template, and the message processing module 3 sends the estimation template to a plurality of recheckers. The reviewer feeds the estimation template with the supplementary suggestion back to the message processing module 3 and transmits the estimation template with the supplementary suggestion to the to-do module 4.
