Description

  The present invention relates to a creation system and a creation method that are useful for the next work plan of a field work in which the same work such as a periodic inspection is repeatedly executed, and that can create a process chart based on work result data.

While the labor force is declining in Japanese society, where the birthrate is declining and the population is aging, productivity per worker must be increased in order to maintain the current industrial competitiveness. Under these demands, plant construction is progressing with the aim of improving productivity, improving the efficiency of incidental work such as office processing by using information and communication technology, making paperless work on site, and shortening working hours. .
In a conventional site, a construction company creates daily work reports (documents) by handwriting input and submits them to the supervisor. The supervisor organizes the daily work report for each construction contractor, stats the number of man-hours per month, and creates a monthly report (for example, electronic data manually input using spreadsheet software). The supervisor submits a monthly report to the head office. At the head office, work results are extracted from monthly reports by visual observation, or work results are extracted from on-site videos, photographs, etc. by visual observation, and a result process table (for example, electronic data manually input using spreadsheet software) is created. . This performance process chart is an operation to be performed after completion of all processes. Based on the actual process schedule obtained in this way, the work period of the next work is shortened and a rational work plan is performed.

  FIG. 12 is an explanatory diagram of a network process chart. The network process chart, which is a kind of the actual process chart based on the actual data, displays the work items classified for each item in the left column and the work schedule of each work item in the right column. The work schedule is displayed as a line segment (length) proportional to the time for each work, and the relationship between the works (main or subordinate) is shown by a chain of dotted arrows.

  In the technique disclosed in Patent Document 1, the person in charge inputs the construction name, the name of the construction company, the start date / end date of the construction period, and the like from the result input screen of the computer during the work for reporting the daily report. Then, the server uses this data to create a performance schedule table composed of a numerical list for each construction name (for example, performance time, performance period, etc.) and a schedule calendar. The obtained performance schedule is reflected in the progress judgment of the entire construction work.

They are a work instruction database 24 in which work data including instructions are recorded, and a work result database 26 in which field work performance data is recorded.

  FIG. 2 is an explanatory diagram of the WBS database. The WBS database 20 classifies work items on the work site into a plurality of levels. Specifically, key (unique identification number of each work), large item (major classification of work item), middle item (medium classification of work item), work item (specific work name, for example, assembly, Curing, wiring, preparatory work, etc.), subsequent work (successive work key), priority (vertical position of the process table, higher position is higher), output flag (whether output to process table is possible) is registered Has been.

Here, the subsequent work of the present embodiment is connection (arrow) information between works for creating a process chart. For example, when the subsequent work key of the 901 work is 902 + 903 work, the subsequent work key of the 902 work is 903, and there is no subsequent work of the 903 work, the work schedule column of the process table can be expressed as shown in FIG.
The priority indicates an attribute for distinguishing the main work from the additional work accompanying it. This priority can be expressed by a numerical value (1 to n), for example, and the lower the numerical value, the more the main work is recognized, and the upper table is displayed when the process chart is created.
The output flag is a marker indicating whether or not to display (output) the process table according to the importance of the work. As an example, the output flag can be expressed as 1: put in the process table, 0: do not enter the process table, and the like.

The process chart creation software as the process chart creation means plays a role of displaying the process quantity. The process chart of this embodiment is a process chart created on the basis of actual data, and as an example, in the case of a network process chart that is a kind of process chart, work items divided into items in the left column and each in the right column The work schedule for the work item is displayed. The work schedule is displayed as a line segment (length) proportional to the time for each work, and the relationship between the works (main or subordinate) is shown by a chain of dotted arrows.

[Work site]
The work site terminal 14 is arranged at the work site, connected to the server terminal 12 through a network 30 described later, reads and displays a work instruction (see FIG. 5) managed by the server terminal 12, and displays various data. On the other hand, it is a terminal that makes it possible to input work results.
The field terminal 14 records a CPU (Central Processing Unit) for executing an application program, a RAM (Random Access Memory) for temporarily storing processing contents during execution of the application program, application software, and the like, similarly to the server terminal 12. It is a personal computer (hereinafter simply referred to as a PC) having a memory, a display unit, an input unit, a wired or wireless communication unit, or a processing board, and is a terminal responsible for input / output of information regarding work. In addition, the information read from the server terminal 12 and various data rewritten by the input information are temporarily recorded in the memory, and the data read from the server terminal 12 is displayed and necessary information is input.

Specifically, a projector or the like may be used, and the display screen may be projected onto the whiteboard 18 or the like installed at the site by being connected to the video output of the site terminal 14. If there is no whiteboard 18 or the like, the display screen may be projected onto an appropriate wall surface. In this way, the display screen is projected onto the whiteboard 18 or the like, and the operator can confirm the contents even from a distance.
The network 30 that connects the server terminal 12 and the field terminal 14 may be a network that uses a wide area network such as the Internet. However, when information security is considered, a closed network such as a VPN (Virtual Private Network) is used. It is desirable to use Also, the connection format may be wired or wireless.

[Schedule creation method]
A process chart creation method using the process chart creation system of the present invention having the above configuration will be described below. FIG. 7 is a process flow diagram of the process chart creation method of the present invention.

<1. Issuing work instructions (1 in Fig. 1)>
The instruction book creation support software is activated on the server terminal 12 installed in the office of the work site. After the instruction book creation support software is activated, a plurality of work items scheduled for the current day (or the next day) are arbitrarily selected from the WBS database 20, and a work instruction sheet is issued (S1). This work is performed by the supervisor at the office of the work site. The input information is automatically registered in the work instruction database 24 after the work instruction is issued (S2).

<2. Display work instructions (2 in FIG. 1)>
When the work instruction is created and issued, the content of the work instruction obtained and output by referring to the work instruction database 24 via the field terminal 14 is displayed on the whiteboard via the projection means 16 on the site. 18 etc. (S3). Such data transfer, output, and display can be performed as needed or in real time. For this reason, it is not necessary to perform the work of copying the same information as the information described in the work instruction many times, and the time can be reduced.
At the work site, the data of the work instruction entered by the projection means 16 via the server terminal 12 is displayed on the whiteboard 18 and the like, and the work of the day is confirmed together with the supervisor. The worker can check the contents of work assigned to himself / herself, the scheduled work time, etc. by looking at the display information (work items, personnel assignment, etc.) projected on the whiteboard 18 or the like.

<3. Enter work results (3 in Fig. 1)>
During the field work or after the work is finished, the work input operation is performed. In the input of work results, the work time of actual work with respect to the scheduled work is entered. For example, in the input of the actual work time, for example, when a work schedule as shown in FIG. 8 is displayed and the work time column for any work item is selected, a screen on which the work time (schedule) for the corresponding work item is input is displayed. Is displayed. In addition, regarding the display of work time, the visibility in the field can be improved by showing in strip shape. On the other hand, the terminal operator inputs the work time (actual result). The input of the work time (actual result) is shown in a band shape along the time zone, similarly to the work time (planned). Here, by displaying the name of the worker or the number of workers with respect to the work time zone, it is possible to keep a record of how many people and how long the work takes (FIG. 8). In the working hours (actual), the number of workers is incidentally displayed). This is because the number of persons in charge is input in advance for each work item, but in actual work at the construction site, it is common for the number of persons to move around, including the relocation of personnel. By leaving such a record, it can be reflected in the creation of a work schedule in the next work.
The input of the work time (actual result) can be performed after all the work on the day is completed, or can be performed at the stage where each work is completed. The input work is mainly performed by a supervisor who confirms the site.
All the information input as described above is registered in real time in the work record database 26 of the server terminal 12 (S4), and can be read from all the field terminals 14.

<4. Create a process chart (4 in Fig. 1)>
Calculation processing is performed based on information registered in the WBS database 20 and the work performance database 26 to automatically create (output) process table data.
Here, the process chart data created by the process chart creation system 10 of the present invention is created in a highly versatile CSV file format. Using this data, it is necessary to convert the data into a WBS file format in order to output it with a commercially available process chart creation software, in other words, to display the process chart.
Before the process chart data is output in the CSV file format, the cleansing process (clarification process) shown below is executed for automatic creation.

[Integration of work time of each work (S5)]
The work time of each work is integrated with respect to the item whose work output flag is 1 (displayed in the process chart). FIG. 9 is an explanatory diagram of integration of work time. When it is desired to obtain detailed results data for each work item, it is necessary to record a plurality of results information for the same work. For example, when it is desired to take a break, or when the number of workers engaged changes, it is necessary to handle each as separate performance data. Therefore, as shown in FIG. 9, the work item A may be registered as a plurality of record data (for example, morning and afternoon on the same day, date and time spanning multiple days, etc.).
In this case, first, the earliest time from a plurality of start dates is set as the start date after integration (20XX / 03/01 9:00). The latest time from a plurality of end dates is set as the end date after integration (20XX / 03/02 16:00). The work time is basically calculated from the difference between the end time and start time after integration. At this time, if the day is exceeded, the working hours are taken into account and the working hours for each day are added together (the working time of work A is 13 hours).
Thereby, the overlapping display in the process chart of the same work performed several times can be avoided, and it can be displayed as a single work. For this reason, the man-hour required for preparation of a process schedule can be reduced, and the burden of process schedule creation can be reduced. In addition, information necessary for creating a process diagram can be arranged and displayed visually in an easy-to-view manner, so that the degree of recognition can be increased and the work contents can be easily grasped.

[Overlapping detection and priority calculation (S6)]
FIG. 10 is an explanatory diagram of overlap detection and priority calculation.
Although the work has the same priority and is scheduled to be performed at a different date and time in the plan, the work date and time often deviates due to sudden factors, so the work time is indicated for a plurality of operations A to D. When displaying as a line segment, there may be an overlap (operation C and operation D in FIG. 10). With overlap detection, such an overlap is detected.
When the overlap is detected, priority calculation is performed. The priority calculation is a process of lowering the priority of the work having the largest number of these factors among the factors in which the work time during the overlapping work is short, the number of workers is small, and the priority of the WBS database 20 is low. As an example, the overlap of the work C and the work D is eliminated by dropping the priority of the work D in FIG. 10 from 2 to 3.
Thereby, it is possible to avoid overlapping display in the process charts of different plural works and display them for each work. For this reason, the man-hour required for preparation of a process schedule can be reduced, and the burden of process schedule creation can be reduced.

[Subsequent (Relation) Judgment (S7)]
FIG. 11 is an explanatory diagram of the subsequent determination. Actually, in the field work, due to various external uncertain factors (such as weather), the work D does not proceed as planned (the work D is performed after the work C in FIG. 11 and the work subsequent to the work C is set as the work D). In many cases, when the start time of the work D (following) is earlier than the end time of the work C (preceding) (work C and work D in FIG. 11), it is inconsistent with the setting of the subsequent work in the WBS database. Will occur. For this reason, in such a case, the relationship between the preceding work (work C) and the subsequent work (work D) is canceled and the data after the cancellation is output.
As a result, it is possible to avoid a contradiction between tasks in the preceding and succeeding relationships and display them as a single task. For this reason, the man-hour required for preparation of a process schedule can be reduced, and the burden of process schedule creation can be reduced.
After executing the cleansing process (pre-processing) of the process chart data, a CSV file of the process chart data is output (S8).
Next, the CSV file is converted into a WBS file (S9).
The process table data converted into the WBS file by the process table creation software is read (S10), and the process table is output (S11).

As described above, the process chart creation system of the present invention has been described in a one-to-one relationship between the office and the work site. However, the present invention is not limited to this, and the office and a plurality of work sites (for example, subsequent work following the main work) Even if it is).
According to such this invention, the duplication description location of the work time of the work item in a process table | surface can be isolate | separated easily. Moreover, the man-hour required for preparation of a process schedule can be reduced, and the burden of process schedule creation can be reduced.
The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
Moreover, the present invention is not limited to the combinations shown in the embodiments, and can be implemented by various combinations.
