Description

  The present invention relates to a work support system, a work support method, and a program.

  At work sites represented by factories, contrivances are made to improve work efficiency. As a relatively simple device of this type, there is a case where the work content and the time required for the work are manually recorded for each worker, and a work plan is made based on this record. However, manual recording is very complicated. Therefore, a technique for simply performing such recording has been proposed (see, for example, Patent Document 1).

  Patent Document 1 collects the contents and work times of work performed by a plurality of devices, and uses the position information of the operator in the factory to determine the time zone in which the operator was in the vicinity of each device. Describes a technique for associating the content of an event that occurred and the event occurrence time with an operator.

  At the work site that employs the cell production method, each process can be regarded as an independent line, and therefore, a variety of small-quantity production can be realized by performing different work in each work cell. Here, the worker has a weak point in the assigned process, and the work volume of each work cell depends on the proficiency level of the worker in charge. For this reason, in order to arrange workers appropriately, it is necessary to grasp the proficiency level of each worker for various processes.

  However, the technique described in Patent Document 1 cannot grasp the proficiency level. In addition, there is a fact that another person directly observes the work by the worker in order to grasp the proficiency level, or that the manager at the work site estimates the proficiency level based on experience and places the worker. is there. For this reason, in order to grasp the proficiency level, a new complicated work is required, or an experienced person who is familiar with all the work is required. And the proficiency level grasped in this way is not necessarily accurate, and can be a factor for creating a work plan with low efficiency. Therefore, there is room for improving the work efficiency by supporting the work by making it easy to accurately grasp the proficiency level.

  The present invention has been made in view of the above circumstances, and an object thereof is to improve work efficiency.

  In order to achieve the above object, the work support system of the present invention acquires position information indicating positions of workers in a region where a plurality of devices for performing different work by the workers is acquired, and Among them, the device specifying means for specifying the device closest to the worker, the history management means for acquiring and managing the history information indicating the work time taken from a plurality of devices, and the worker specified by the device specifying means And a proficiency level determining means for determining and outputting the proficiency level of the worker from the apparatus and the work time of the apparatus indicated by the history information.

  According to the present invention, the proficiency level of the worker is determined and output. For this reason, it becomes easy to grasp | ascertain the exact skill level of an operator. As a result, the work efficiency can be improved by supporting the work.

Specifically, the proficiency level information generation unit 52 identifies the worker 20 closest to the work devices 11 to 14 at the work start time. In this way, the proficiency level information generation unit 52 associates the work time calculated by the work time calculation unit 51 with the worker 20. Then, the proficiency level information generation unit 52 determines the proficiency level for each worker 20 based on the work time, and generates proficiency level information 53a indicating the determined proficiency level.

  FIG. 6 shows an example of the proficiency level information 53a. As shown in FIG. 6, the proficiency level information 53a includes the identification number of the worker 20, the identification number of the work lot, the work target model, the work date, and the actual work time per product of the work target model. Are in table format. Since the proficiency level according to the present embodiment is equal to the actual work time per unit, the proficiency level value decreases as the operator 20 becomes proficient in the work. “0:37” in FIG. 6 means zero time 37 minutes.

  The worker arrangement unit 60 acquires the proficiency level information 53a from the proficiency level determination unit 50, and plans the arrangement of the workers 20 for advancing efficient work based on the proficiency level.

The arrangement planning unit 62 acquires proficiency level information 53 a indicating the proficiency level of each work target model for each worker 20 from the proficiency level determining unit 50. And the arrangement | positioning plan part 62 produces | generates the arrangement | positioning information 63a by determining the working apparatus allocated to each worker 20 based on the proficiency level information 53a and a work plan. Details of the plan by the arrangement planning unit 62 will be described later.

  The display unit 63 is mainly realized by the output unit 84 of the worker placement unit 60. The display unit 63 displays the arrangement information 63a. However, the display unit 63 may process and display the arrangement information 63a. For example, the display unit 63 may display only the arrangement of the worker 20 corresponding to the latest work plan in the arrangement information 63a, or detailed arrangement information 63a according to the request of the operator 20 or the administrator. The proficiency level information 53a may be added and displayed.

  FIG. 7 shows an example of the arrangement information 63a. As shown in FIG. 7, the arrangement information 63a includes a work device identification number, a work lot identification number, a work target model, a work target number, a worker, a work start scheduled time, and a work end schedule.

And the assistance information output unit 70 produces | generates and outputs the assistance information for assisting the operation | work by the operator 20 based on the acquired information. The support information output unit 70 includes a support information generation unit 71 that generates support information, and an output unit 72 that outputs the support information to the work apparatuses 11 to 14.

  The support information generation unit 71 is realized mainly by the cooperation of the processor 81 of the support information output unit 70 and the communication interface 86. The support information generation unit 71 refers to the proficiency level information 53a when the worker 20 performs a specific work scheduled for the work, and determines the worker 20 according to the length of the period that has elapsed since the last specific work. Generate support information to support. Specifically, the support information generation unit 71 sets the previous time for the same model by the worker 20 indicated in the arrangement information 63a immediately before the current time becomes the scheduled work start time for each of the work devices 11 to 14. Calculate the length of the period that has elapsed since the work day. The length of this period is calculated by referring to the work day included in the proficiency level information 53a shown in FIG. Then, the support information generation unit 71 selects a one-point advice including precautions and confirmation items during work according to the length of the period according to the proficiency level from a list of preset advices. Generate support information. For example, when the worker 20 is relatively unfamiliar with the work, if the previous work day is one month or more before, the work manual is generated as support information before the work.

  The output unit 72 is mainly realized by the communication interface 86 of the support information output unit 70. The output unit 72 displays the support information on the work devices 11 to 14 by transmitting the support information corresponding to each of the work devices 11 to 14 to the work devices 11 to 14.

  Next, a series of processes that occur due to the work performed by the worker will be described with reference to FIG. Although the case where the work apparatus 11 is used will be described with reference to FIG. 8, a series of processes similar to those of the work apparatus 11 occur even in work using the work apparatuses 12 to 14.

  As shown in FIG. 8, when the work is started, the worker 20 reads the instruction sheet 21a with the input device 11a (step S1). Specifically, the worker 20 reads the barcode written on the instruction sheet 21a using a barcode reader.

  Next, the history management unit 40 registers the history information 42a (step S2). Specifically, the history information collection unit 41 adds a record that associates the work device, the work lot, the work target model, the operation status code, and the start time of the operation time illustrated in FIG. The operation status code at this time is “0000” indicating normal operation. Note that the work target model may be input from the instruction sheet, or may be acquired from an external system as a model associated with the work lot.

  Next, the history management unit 40 determines whether the work is interrupted (step S3). Specifically, the history information collection unit 41 collects information about interruption using a work management function called MES (Manufacturing Execution System) installed in the work equipment, and determines whether the work is interrupted. To do. The interruption of work includes interruption due to abnormality of work equipment and interruption due to a break of the worker.

  If it is determined that the work has not been interrupted (step S3; No), the process proceeds to step S5. On the other hand, when it is determined that the work has been interrupted (step S3; Yes), the history management unit 40 updates the history information 42a (step S4). For example, the history information collection unit 41 adds a record in the history information 42a in which the operation status code “0001” indicating an abnormality is associated with the start date / time and end date / time of interruption.

  Next, the history management unit 40 determines whether or not the work has been completed (step S5). Specifically, the history information collection unit 41 determines whether or not the worker 20 who has finished the work reads the instruction sheet 21a with the input device 11a and inputs the number of products to be worked into the work device 11. .

  When it is determined that the work has not been completed (step S5; No), the processes after step S3 are repeated. On the other hand, when it is determined that the work is completed (step S5; Yes), the history management unit 40 updates the history information 42a (step S6). Specifically, the history information collection unit 41 adds the number of units determined to be input in step S5 and the current time as the end date and time to the record registered in step S2.

  Thereafter, the work process ends. Since the above processing is repeated every time work is performed, the history regarding the work of the work device 11 is accumulated in the history information 42a. Similarly, the history regarding the work of the work devices 12 to 14 is also accumulated in the history information 42a.

  Next, the proficiency level determination process executed by the proficiency level determination unit 50 will be described with reference to FIG. In the proficiency level determination process, first, the work time calculation unit 51 obtains history information 42a by making a request to the history management unit 40 (step S11).

  Next, the work time calculation unit 51 is normal from the start date / time and end date / time of the operation time associated with “0000” which is the operation status code indicating normal operation among all the records constituting the history information 42a. The length of the working time is calculated (step S12).

  Next, the work time calculation unit 51, for each work lot, the total length of work interruption times associated with “0001”, which is an operation status code indicating an abnormality, or “0002”, which is an operation status code indicating a break. Is calculated (step S13).

  Next, the work time calculating unit 51 calculates the actual work time in one work by subtracting the work interruption time calculated in step S13 from the normal operation time calculated in step S12. (Step S14).

  Next, the work time calculation unit 51 calculates the work time per unit for each work target model by dividing the actual work time by the number of work targets (step S15). Here, the work time per vehicle is the average value obtained for each model for each worker 20.

  Next, the proficiency level information generating unit 52 obtains the work device information 32c by making a request to the device specifying unit 30 (step S16).

  Next, the proficiency level information generation unit 52 determines the proficiency level and generates proficiency level information 53a (step S17). Specifically, the proficiency level information generation unit 52 determines the work time per unit calculated in step S15 as the proficiency level. In addition, the proficiency level information generation unit 52 corresponds to the operation status code by comparing the start date and time of the operation time associated with the operation status code “0000” indicating normal operation with the work device information 32c. The worker 20 who performed the work is specified. Then, the proficiency level information generation unit 52 generates proficiency level information 53a illustrated in FIG. Thereby, the proficiency level is determined for each work target model for each worker 20. Thereafter, the proficiency level determination unit 50 ends the proficiency level determination process.

  Next, worker placement processing executed by the worker placement unit 60 will be described with reference to FIG. As shown in FIG. 10, in the worker placement process, the work plan acquisition unit 61 acquires a work plan (step S21). Here, the number of work target products planned in the work lot planned nth for the mth work device among the work devices 11 to 14 is defined as Wmn.

  Next, the arrangement planning unit 62 acquires the proficiency level information 53a (step S22). Here, among the plurality of workers 20, the working time per unit for the j-th model by the i-th worker 20 is Pij. The j-th model means a model corresponding to the j-th number when numbers indicating the models are arranged in order.

  Next, the arrangement planning unit 62 performs the initial arrangement of the worker 20 and sets the provisional pattern (step S23). The initial arrangement corresponds to a random assignment of workers 20 to the work plan. FIG. 11A shows an example of this initial arrangement. In FIG. 11A, the worker 21 is assigned to all work lots to the first (m = 1) work device 11. The second (m = 2) work device 12 is assigned workers 22 for all work lots, and the third (m = 3) work device 13 is assigned workers 23 for all work lots. Is assigned.

  Next, the arrangement planning unit 62 calculates the total sum of work times for all work lots in a provisional pattern as a provisional value (step S24). For example, in FIG. 11A, if the work target model scheduled for the work lot “A001” is the first (j = 1), the time taken for the work lot “A001” to be completed is the number of work pieces. Since “100” is “100”, it can be calculated using an arithmetic expression of P11 × 100. Here, the sum total of the work time is expressed as L (X). X means an arrangement pattern of the worker 20. L (X) can be calculated using the following equation (1).

      L (X) = Σ (Wmn × Pij) (1)

  Next, the arrangement planning unit 62 changes the arrangement of the worker 20 from the provisional pattern (step S25). To change the arrangement, a combination of meta solutions represented by the local search method is used. In this method, the assignment of the workers 20 is partially exchanged in order with respect to the initial arrangement in step S23, and an arrangement that minimizes the total work time is searched by repeating this exchange process. FIG. 11B shows an example of an arrangement changed from the initial arrangement. In FIG. 11B, the workers 20 of the work lots “A001” and “B001” are replaced from the initial arrangement. In step S23, as the pattern whose arrangement is changed from the provisional pattern, a number of different patterns determined according to the search method are derived.

  Next, the arrangement planning unit 62 calculates the total work time for each pattern changed in step S25 (step S26). Specifically, the arrangement planning unit 62 calculates the total work time L1 (X), L2 (X), L3 (X)... Lk (X) using the above-described equation (1).

  Next, the arrangement planning unit 62 sets the minimum value among the total work time calculated in step S26 as the update value, and sets the pattern corresponding to the update value as the update pattern (step S27). Here, the update value La is calculated as La = min Lk (X).

  Next, the arrangement planning unit 62 determines whether or not the update value La (X) is greater than or equal to the provisional value L (X) (step S28). When it is determined that the update value La (X) is not equal to or greater than the provisional value L (X) (step S28; No), the arrangement planning unit 62 replaces the provisional pattern with the update pattern and substitutes the update value for the provisional value. (Step S29). Then, the arrangement planning unit 62 repeats the processes after step S25. As a result, the update pattern corresponding to the update value La (X) is further changed to calculate the total work time. For example, as shown in FIG. 11C, the arrangement is further changed. The arrangement shown in FIG. 11C corresponds to the arrangement in which the workers 20 of the work lots “B001” and “C001” are replaced from the arrangement shown in FIG.

  On the other hand, when it is determined that the update value La (X) is greater than or equal to the provisional value L (X) (step S28; Yes), the arrangement planning unit 62 determines the arrangement of the provisional pattern corresponding to the provisional value L (X). As an arrangement corresponding to an efficient local optimum solution, arrangement information 63a indicating this arrangement is output (step S30). Thereafter, the worker placement process is terminated.

  In the worker placement process described above, the meta solution is used when placing the worker 20, but the present invention is not limited to this. For example, a search method using a binary search method may be employed.

  As described above, according to the work support system 100, the proficiency level is determined and output for each worker 20. Thereby, the manager who manages the work in the work area 10 can easily grasp the proficiency level and make an efficient work plan. As a result, work efficiency can be improved.

  The worker placement unit 60 planned the placement of the worker 20 based on the proficiency level. Thereby, the administrator can easily realize the personnel assignment for performing the efficient work.

  Further, the support information output unit 70 outputs support information corresponding to the length of the period that has elapsed since the previous work. Thereby, even if it is a case where a long period has passed since the previous work, the worker 20 can efficiently perform the work, and can suppress variations in work quality resulting from the proficiency level.

  Further, the proficiency level determination unit 50 determines the proficiency level for each model to be worked. Thereby, it becomes possible to plan an efficient work in consideration of the weaknesses and weaknesses according to the model of the worker 20.

  Further, the proficiency level determination unit 50 determines the actual work time per unit as the proficiency level. Thereby, the calculation for the worker placement unit 60 to plan the placement can be easily defined.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.

  For example, in the above-described embodiment, the device specifying unit 30, the history management unit 40, the proficiency level determining unit 50, the worker placement unit 60, and the support information output unit 70 have been described as separate computer devices. Is not limited. For example, the work support system 100 may be configured with a part or all of these devices as an integrated computer device.

  In the above embodiment, the actual work time per vehicle is equal to the proficiency level, but the present invention is not limited to this. For example, the proficiency level may be calculated by using an arithmetic expression from the actual work time per unit, or may be a value corresponding to the actual work time per unit. For example, if the range of 0:30 to 0:45 of the actual work time per unit and the proficiency level “3” are associated in advance, “0:37” is calculated as shown in FIG. The proficiency level is obtained as “3” from the actual work time. In this case, the proficiency level value increases as the actual work time decreases.

  Moreover, in the said embodiment, although assistance information was produced | generated according to the length of the period which passed since the last work day, it is not limited to this. For example, the support information output unit 70 may generate support information with reference to the history information 42a on the basis of the variation in the actual work time per unit for the model scheduled for work. If this variation is large, the worker is not familiar with the work, so it is preferable to present the basic support information to the worker. If this variation is small, the worker is accustomed to the work. Therefore, it is preferable to present support information with confirming contents to the worker.

  The functions of the work devices 11 to 14, the device specifying unit 30, the history management unit 40, the proficiency level determination unit 50, the worker placement unit 60, and the support information output unit 70 according to the above-described embodiment can be achieved by using dedicated hardware. It can also be realized by a normal computer system.

  For example, the program P1 stored in the auxiliary storage unit 83 is stored in a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), and distributed. By installing the program P1 in the computer, a device that executes the above-described processing can be configured.

  Further, the program P1 may be stored in a disk device included in a server device on a communication network represented by the Internet, and may be downloaded onto a computer, for example, superimposed on a carrier wave.

  The above-described processing can also be achieved by starting and executing the program P1 while transferring it through the communication network.

  Further, the above-described processing can also be achieved by executing all or part of the program P1 on the server device and executing the program P1 while the computer transmits / receives information related to the processing via the communication network. .

  Note that when the above functions are realized by sharing an OS (Operating System) or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. It may also be downloaded to a computer.
