Description

  The present invention relates to a work management system that uses a computer to manage a plurality of work schedules such as maintenance inspections that are performed in facilities that require maintenance inspection such as power plants and factories, and work management that allows the computer to function as such a system. Regarding the program.

  In facilities that require maintenance and inspection, for example, thermal power plants, many inspections and maintenance work are concentrated in a short period of time, especially during regular periodic inspection work stipulated by laws and regulations. In such a case, if a plurality of operations are performed at the same time in the same area, the probability that a work accident will occur increases. For example, there is a possibility that a test run may be performed during equipment inspection work, harming another nearby worker, or a tool or the like may fall due to work on the floor ceiling and harm the floor worker. There is.

  In order to prevent such an accident in advance, it is necessary to identify mixed work (work with overlapping work periods and work areas) and call attention to workers in charge of these work in advance. Conventionally, mixed work is checked at the work site of a thermal power plant by the following method.

  That is, at the work planning stage, the person in charge of each work conducts a meeting regarding work schedules, and when it is determined that mixed work occurs, a work schedule list for mixed work is created. Then, in the work execution stage, the worker in charge of the mixed work is informed at a pre-work meeting or the like. In addition, a work schedule list of mixed work is posted on the site, a floor plan is pasted on a bulletin board, and the position of the mixed work is marked with a magnet or a pin. During the work, each worker verbally communicates work procedures, etc., and works while making adjustments.

However, the conventional check method described above has the following problems.
(1) Check mistakes are likely to occur because it is based on manual judgment. In a thermal power plant, when work is concentrated, hundreds of work is performed per day, so it is difficult to accurately extract mixed work by visual confirmation of materials.
(2) If any work is delayed and does not end within the scheduled period, it is necessary to redo the mixed work judgment performed at the planning stage. There is a high possibility that it will not be possible to redo due to cost problems.
(3) Delay in reporting work delays may affect the next day's work. Work that has been determined to have no mixed work may be in a mixed work state due to work delays for work that was scheduled to end on the day before the work start date, but if work delay reporting is delayed, Work starts with recognition without mixed work.

  Since manual checks have the above-mentioned problems, a schedule management method using a computer has been proposed. For example, Patent Document 1 discloses a process management system in which a scheduled work schedule of maintenance work is recorded in a process database and can be called up and displayed from a terminal as necessary.

JP 2003-233409 A

  However, in the system disclosed in Patent Document 1, if any work is delayed, the administrator needs to correct the schedule by operating the terminal (see paragraph 0054), but generally the work is delayed. In such a case, the progress of the actual work is given priority, and there is a high possibility that the input to the terminal will be postponed.

  The present invention has been made in view of the above-described problems of the prior art, and the problem is that even when the number of operations is large and the occurrence of delayed operations is not reported, it is accurately mixed. An object of the present invention is to provide a work management system and a work management program capable of judging work.

  The work management system according to the present invention is registered for each work in a system that manages whether or not a plurality of work schedules overlap in the same area in a facility based on work information registered in a computer. Work information storage means for storing a work area, scheduled work period, and work state, area overlapping work extraction means for extracting work performed in the same area as the work to be determined from the work information storage means, and work information storage means From the period extension means to extract the work whose work status is working and the scheduled work period ends before the present time and extend the scheduled work period by a predetermined period, and the work list processed by the period extension means Both hands of a period overlapping work extracting means for extracting a work whose scheduled work period overlaps with the work to be, and an area overlapping work extracting means and a period overlapping work extracting means Characterized in that it comprises an output means for outputting the work extracted in duplicate as a mixed operation of overlapping the work to be determined, the a.

  It is desirable that the above-mentioned period extension means performs processing for the work extracted by the area duplication work extraction means. Further, the scheduled work period has fields of a scheduled start date and a scheduled end date input at the time of registration, and an end determination date set by the period extension means. , Set the date extended for a predetermined period on the end date of work whose scheduled end date is before the current date, set the scheduled end date on the end date of work other than that, and the period duplicate work extraction means will start It is desirable to determine the presence or absence of duplication based on the work period defined by the date and the end determination date.

  On the other hand, the work management program according to the present invention is a program that causes a computer to function as a work management apparatus that manages whether or not a plurality of work schedules overlap in the same area in a facility based on registered work information. In the computer, an area duplication work extraction function for extracting work to be performed in the same area as the work to be determined from the work information database storing the work area registered for each work, the work scheduled period, and the work state; The period extension function that extracts the work whose work status is being worked from the work extracted by the area overlapped work extraction function, and the scheduled work period ends before the present time, and extends the scheduled work period by a predetermined period, and the period extension function For the work list processed by, the period overlap work that extracts the work that is to be judged and the work scheduled period is duplicated The output function and the output function that outputs the work extracted redundantly by both the area overlapping work extraction function and the period overlapping work extraction function as a mixed work that overlaps with the work to be judged are realized. And

  In addition, the work information database has fields of a scheduled start date and a scheduled end date input at the time of registration and an end determination date set by the period extension function as the scheduled work period. Set a date that is extended for a predetermined period on the work end judgment date for which the scheduled end date is before the current date, and set the scheduled end date on the other work end judgment date to extract duplicate work. It is desirable for the function to determine the presence or absence of duplication based on the work period defined by the scheduled start date and the end determination date.

  According to the work management system / program of the present invention configured as described above, even when the number of work is enormous, it is possible to quickly and accurately determine mixed work by a check using a computer, and the system Therefore, the mixed work can be accurately recognized even if the occurrence of the delayed work is not reported or entered. Therefore, it is possible to appropriately alert the worker about the mixed work and contribute to work safety.

  Embodiments of a work management program according to the present invention and a work management system to which the work management program is applied will be described below with reference to the drawings. First, an outline of a work management system to which the work management program of the present embodiment is applied will be described with reference to FIG. The work management system 1 includes a single computer 10 and peripheral devices. The computer 10 includes a CPU 11, a hard disk (HD) 20, a memory (RAM) 12, and an interface 13 connected to the CPU 11.

  Note that a display 30, a printer 31, and a keyboard 32 are connected to the CPU 11 of the computer 10 via the interface 13 as peripheral devices.

  In addition to an operating system (not shown), a work management program 21 is installed in the HD 20 and a work information database (DB) 22 is constructed. When activated, the CPU 11 reads the operating system from the HD 20 onto the RAM 13 and executes it, and executes the work management program 21 on the operating system.

  FIG. 1 shows an example in which the work management system is configured by a single computer, but a plurality of terminals are connected via a network using this computer as a server so that input and browsing can be performed from each terminal. May be.

  The work management program 21 installed in the HD 20 is a computer as a work management apparatus that manages whether or not a plurality of work schedules overlap in the same area within the facility in the same period based on the work information registered in the work information DB 22. Make 10 work. This program 21 includes an area overlapping work extraction function 21a for extracting work performed in the same area as the work to be determined from the work information DB 22 storing the work area registered for each work, the work scheduled period, and the work state. A period extension function 21b for extracting a work whose work state is being worked from the work extracted by the area duplication work extraction function 21a and whose work end is before the present time and extending the work scheduled period by a predetermined period; For the work list processed by the period extension function 21b, both a period overlapping work extraction function 21c that extracts a work whose judgment target period overlaps with a work to be determined, an area overlapping work extraction function, and a period overlapping work extraction function An output function 21d that outputs the work extracted in duplicate as a mixed work overlapping with the work to be determined. It contains as Le.

  The work information DB 22 constructed in the HD 20 includes a work schedule table 22a that defines the work status and work schedule period of each work, and a work area table 22b that defines in which area each work is performed. And has.

  The work schedule table 22a, as shown in the sample data in Table 1 below, includes a work code that is a unique number automatically assigned by the system to identify each work, and a work state that indicates the progress of work. , Each field of a work subject indicating a work subject, and a field of a scheduled start date and a scheduled end date that are manually input at the time of registration and an end determination date set by the period extension function 21b as a scheduled work period Have. The work status is set to “under planning”, which is set immediately after new work information is registered, and “approved”, which is set when work is started from the start date of work under planning. "Approved work" is set when the work start date has arrived, "work in progress", "work complete" set when the work completion registration process is performed manually for the work in progress There are four types. In addition, the work start date and the scheduled end date are the start and end scheduled dates of the work period, and the end judgment date is usually the same date as the scheduled end date, but if a delay occurs The date extended by the period extension means 21b is input. In the work schedule table, one work is represented as one line record.

  On the other hand, as shown in Table 2 below, the work area table 22b has three fields of a building, a floor, and a selection area in addition to the same work code as in Table 1. In other words, in this example, it is assumed that the target thermal power plant has a plurality of buildings, and one building has a plurality of floors. Each floor is partitioned into a total of 300 areas of 15 × 20 in a grid pattern. `` Building '' is the building that performs the work, `` Floor '' is the floor in the building, `` Selection area '' is the data representing the selected section in the floor, and is represented by a 300-bit binary number ( Table 2 shows only the upper 35 bits). In this binary number, the 1st to 300th bits correspond to areas 1 to 300, and the value of each bit is “1” when the area is selected as a work area, and when the area is not selected. Becomes “0”.

  When selecting and registering the work area from the computer screen, the building and floor are selected from the options displayed in the pull-down menu, etc., and the area within the floor is arranged in a grid with 300 squares of the floor plan view. Display the divided screen and select the cells corresponding to the work area one by one with a mouse click.

  In the work area table, work area information for one floor of one work is expressed as one line of data. In the example in Table 2, there is a two-line record because the work with work code 00002 is carried out across two floors (both 1F and 2F of the boiler building), and other work is within one floor. Since it is a work, it is shown that it is one line at a time.

The work management program 21 calculates the presence / absence of mixed work based on information registered in the work information DB. Judgment method compares one work (self work) to be judged with a plurality of other work (other work 1 to other work n), and mixes other work that satisfies all of the following conditions 1 to 3 Is determined.
[Condition 1] The other work as the comparison destination is not in a work completion state.
[Condition 2] The work area overlaps between own work and other work.
[Condition 3] The work period (work start date to end determination date) overlaps between the own work and the other work.

  Next, the contents of the work management process executed in the work management system 1 will be described based on the flowcharts shown in FIGS. In the following description, it is assumed that the current date is 2006/01/13. First, prior to determination, work schedule information and work area information are registered in the work information DB (S001). Then, one work (self work) to be determined is selected from the work schedule table 22a (S002). For example, as shown in Table 3 below, the operation C is selected as the own operation.

  Subsequently, from the work specified in the work schedule table 22a shown in Table 1, the self work and the completed work whose work status is “work completed” are excluded (S003), and other work to be compared is compared. A list (first work list) is generated. In this example, work A is a completed work and work C is a self-work, so the first work list excluding these is as shown in Table 4 below.

  Next, based on the first work list, a work whose work area and work area overlap is extracted from other work included in this list (S004), and a second work list is generated. Here, as shown in FIG. 3, the area information of the own work is read from the work area table 22b (S101), and the area information of other work included in the first work list is read from the work area table 22b (S102). Table 5 shows area information for own work, and Table 6 shows area information for other work.

  Then, the work included in Table 6 is selected line by line (S103), and it is determined whether the selected building of the other work is the same as the own work (S104) and whether the floor is the same (S105). If one of the building and the floor is different, the process proceeds to S109, and if both are the same, the logical product for each bit corresponding to the value of the selection area of the own work and the other work is calculated (S106). It is determined whether or not the value of the 300-bit logical product obtained by this calculation is 0 (S107). If it is 0, it is determined that there are no overlapping work areas, and the process proceeds to S109. Therefore, the task is added to the second task list (S108), and the process proceeds to S109. In S109, it is determined whether or not the selected line is the last line. If there is a remaining line, the process returns to S103 to select the next line and repeat the above determination. Return to. As a result of such processing, work with overlapping areas can be extracted as the second work list as shown in Table 7.

  Next, from the other tasks extracted as the second task list, a task whose work period overlaps with the own task is extracted to generate a third task list (S005-S012). Here, first, based on the work code of the second work list, the work status and work period (work start date, scheduled end date) of the corresponding other work are extracted from the work schedule table 22a (S005). The extraction results are as shown in Table 8 below.

  One line is selected from the above extraction result (S006), and it is determined whether the selected work is a delayed work (S007, S008). In other words, here, it is determined that other work is “delayed work” in which the work state is “working” (S007, Yes) and the scheduled end date is older than the current date (S008, Yes). Then, in the line of other work judged to be delayed work, a date obtained by adding one year to the scheduled end date is set in the field of end judgment date (S009), and to the line of other work judged not to be delayed work The date of the scheduled end date is set as it is in the judgment date field (S010). The setting results are as shown in Table 9. That is, since it is assumed that the current date is 2006/01/13, work B satisfies the condition that both the judgments of S007 and S008 are Yes, and the end judgment date is one year on the scheduled end date. Added date 2007/01/11 is set. Since the work E does not correspond to the delayed work, 2006/01/20 which is the same as the scheduled end date is set as the end determination date.

  Although illustration is omitted, the end determination date is set by making the same determination for the own work. As a result, for the self-work C, the scheduled end date is set on the end determination date as shown in Table 10.

  Next, the period from the work start date to the end determination date is regarded as the work period, and it is determined whether the work period of the own work and the work period of other work overlap (S011), and the overlapping other work is mixed. The work is added to the third work list (S012). In the determination of overlapping periods in S011, the relationship between the work period of the own work and the other work can be classified into six patterns shown in Table 11. Table 12 shows the relationship between the work periods for each pattern.

Of the above six patterns, there are only four types of patterns 2, 3, 4, and 6 that have a period overlap relationship. Whether one of the four types is applicable can be determined by the following two conditional expressions. The determination of period overlap in S011 is made based on whether or not the following two conditions are satisfied.
Work start date for own work ≦ Date for judging end of other work and
Work start date of other work ≤ Date of end of own work

  Then, the third work list is generated by performing the processes of S006 to S012 until the last line (S013, Yes), that is, all other work included in the second work list, and this is displayed on the display 30. Or printed out from the printer 31 (S014). The contents of the third work list are as shown in Table 13 below.

  Through the above-described work management processing, in this example, it is determined that work B is the mixed work for the self work C on the current date 2006/01/13.

  As described above, the system automatically determines the delayed work based on the work status, the scheduled end date, and the current date, so that even if a delay occurs, the scheduled end date for the task is manually changed on the computer. There is no need to register, and it is possible to reliably determine mixed work.

  Hereinafter, a specific difference between the case where delay work is automatically set and the case where it is not performed as in the present invention will be described (in the following description, it is assumed that work areas overlap) . If the work period is considered as the work start date to the scheduled end date set in the work planning stage without considering the delayed work, as shown in Table 14, between work B and C whose work status is in work Since there is no overlap of work periods, if work C is determined as a self-work, the result of determination is that there is no mixed work.

  On the other hand, in the system of the present invention, it is determined that the work B is delayed as of January 13, 2006, and the period overlap is determined on the basis of the end determination date obtained by extending the scheduled end date by one year. As shown in Table 15, it is determined that there is an overlap of work periods between the work B and C whose work state is being worked, and the determination result is that the work B is a mixed work with respect to the self work C.

  On the other hand, when the work B is determined as a self-work, the mixed work is determined, and among the work in which work B and work area overlap, the work starts over the next year in addition to the work whose work start date to scheduled end date overlap. Since the work scheduled to be performed is also determined as a mixed work, it is possible to transmit an alert to other work from the delayed work side. In addition, even if a work that is scheduled to start in the future is determined as a mixed work and the delayed work is determined as a mixed work, the risk of mixed work is detected from the work planning stage. Can improve safety.

It is a block diagram which shows the work management system concerning embodiment of this invention. It is a flowchart which shows the effect | action of the work system shown in FIG. It is a flowchart which shows the process of S004 in detail among the flowcharts shown in FIG.
