Description

  Embodiments described herein relate generally to a work shift creation support apparatus and a program.

  Conventionally, techniques for supporting creation of work shifts have been proposed. In this type of technology, a work shift is created based on a shift condition (working desired date and time) desired by each worker.

  Depending on the work environment, the busy date and time may vary, so even if the number of attendance is the same, the fatigue status may vary from person to person. However, in the prior art related to creation of work shifts, work shifts are not created in consideration of the fatigue status of workers who actually performed work. For this reason, even if the work shift desired by the worker can be assigned, there is a possibility that fatigue will increase for a specific worker.

  The work shift creation support apparatus of the embodiment includes a work history storage unit, a fatigue level determination unit, a first setting unit, and a work shift creation unit. The work history storage means stores a work history in which a work type of work performed by each worker is associated with a time required for performing the work. For each work history of each worker, the fatigue degree determination means multiplies a predetermined weighting factor according to the work type and the required time, and calculates the fatigue degree indicating the degree of fatigue of each worker based on the multiplication result. decide. A 1st setting means sets the 1st condition which defined the upper limit of the continuous working day which can be continuously allocated to the said worker according to the fatigue degree of each worker. The work shift creation means creates a work shift that defines the work date and time of each worker based on the first condition.

The display unit 15 is a display device such as an LCD (Liquid Crystal Display), and displays various types of information in accordance with instructions from the CPU 11. In addition, it is good also as a form which receives operation content in cooperation with the display part 15 by making the input part 14 into a touchscreen structure.

  The storage unit 16 is a storage medium such as an HDD (Hard Disk Drive) or a flash memory, and stores various programs and various files related to creation of work shifts. The files stored in the storage unit 16 include a worker management table 161 that manages information on workers to be created for work shifts, a work history table 162 that manages the work history of each worker, and a weight coefficient for each work. Coefficient table 163 for managing the fatigue level, a fatigue level determination table 164 used for determining the fatigue level, a skill level determination table 165 used for determining the skill level, and a shift request table for managing shift conditions desired by each worker 166 and a constraint condition table 167 for managing constraint conditions when creating work shifts are stored.

  FIG. 2 is a diagram schematically illustrating an example of the data configuration of the worker management table 161. As shown in the figure, the worker management table 161 stores a worker ID as identification information for identifying each worker in association with the fatigue level and skill level of the worker. Here, the fatigue level is derived to a fatigue level determination unit 111 described later, and the skill level is derived by a skill level determination unit 112 described later. A method for deriving the fatigue level and the skill level will be described later.

  FIG. 3 is a diagram schematically illustrating an example of the data configuration of the work history table 162. As shown in the figure, the work history table 162 includes a worker ID of the worker who performed the work, a work ID indicating the work content, a date and time (work date and time) of the work, and a requirement required for the work. Stored in association with time. Here, the work content represents various work included in the work that the worker is engaged in. For example, when the worker is a nurse engaged in a hospital or the like, various operations such as temperature measurement, blood pressure measurement, and input assistance are the work contents. In addition, the registration method of the work history in the work history table 162 is not particularly limited, and each worker or an administrator who manages the worker may manually register each time the work is completed. The execution state of the work performed by the administrator may be automatically registered as the work history by using a predetermined system capable of recording the action.

  FIG. 4 is a diagram schematically illustrating an example of the data configuration of the weighting coefficient table 163. As shown in the figure, the weight coefficient table 163 stores the work ID of each work content and the weight coefficient in association with each other. Here, the weighting coefficient is used when the degree of fatigue is derived, and a value corresponding to the work content (work ID) load is registered. It is assumed that a larger value is assigned to the weighting factor as the work content is higher in load.

  FIG. 5 is a diagram schematically illustrating an example of a data configuration of the fatigue level determination table 164. As illustrated in FIG. As shown in the figure, the fatigue level determination table 164 stores a fatigue level divided into a plurality of stages and a threshold range that serves as an index when determining the fatigue level. FIG. 5 shows an example in which the degree of fatigue is five stages, but the present invention is not limited to this.

  FIG. 6 is a diagram schematically illustrating an example of the data configuration of the skill level determination table 165. As illustrated in FIG. As shown in the figure, the skill level determination table 165 stores a work ID for identifying each work content, a threshold range for the work content, and a skill level for each work corresponding to the threshold range in association with each other. Yes. FIG. 6 shows an example in which the skill level for each operation is five levels, but the present invention is not limited to this.

  FIG. 7 is a diagram schematically illustrating an example of the data configuration of the shift request table 166. As shown in the figure, the shift request table 166 stores a worker ID of a worker and a shift condition desired by the worker in association with each other. Here, the shift condition indicates a work shift assignment condition desired by the worker, that is, assignment or non-assignment of a work shift to a specific date, day of the week, or time. For example, FIG. 7 shows that the shift conditions for the worker 01 are not to assign night shifts every Saturday and not to assign night shifts on the 18th. In addition, as a shift condition for the worker 02, it is indicated that early departure is not assigned on the 3rd and 15th. In this embodiment, the working hours include day shifts (for example, 8:00 to 17:00), early departure (for example, 6:00 to 15:30), late departure (for example, 12:00 to 21:00), night shift (for example, 20 It is assumed that work shifts are assigned in units such as (hours to 8:00).

  FIG. 8 is a diagram schematically illustrating an example of the data configuration of the constraint condition table 167. As shown in the figure, the constraint condition table 167 stores working hours, fatigue levels, and continuous work conditions at the fatigue levels in association with each other. Here, the continuous working condition indicates an upper limit value of the number of days for which work shifts can be continuously assigned for the same working hours. For example, in working hours “night shift”, continuous duty conditions for workers with fatigue level “1” or “2” are continuous duty conditions for continuous duty conditions for “5” days, and continuous duty conditions for workers with fatigue level “3” or “4”. For a worker with a fatigue level of “5” for “4” days, the continuous work condition is set to “3” days. Thus, by reducing the value of continuous work conditions (days) as the degree of fatigue increases, the workers with high levels of fatigue are rested. In the working day “day shift”, the continuous duty condition is “6” days regardless of the degree of fatigue.

  Returning to FIG. 1, the communication I / F 17 is an interface for performing data communication with an external apparatus via a network such as a LAN (not shown). The CPU 11 controls the communication I / F 17 and transmits / receives various data to / from an external device. Although not shown, the work shift creation support apparatus 10 includes a timing device (not shown) such as an RTC (Real Time Clock), and can acquire date and time information representing the current date and time based on the timing of the timing device. .

  Next, the functional configuration of the work shift creation support apparatus 10 will be described. As shown in FIG. 1, the CPU 11 of the work shift creation support apparatus 10 cooperates with a program stored in the ROM 12 or the storage unit 16 to determine the fatigue level determination unit 111, the skill level determination unit 112, and the work shift creation unit 113. Is realized.

  The fatigue level determination unit 111 is a functional unit that derives, for each worker, the fatigue level accumulated in the execution of the work content based on the results of the work content of each worker registered in the work history table 162. Here, the fatigue level numerically indicates the degree of physical and mental fatigue accumulated by the execution of work.

Specifically, the fatigue level determination unit 111 sets each worker ID registered in the work history table 162 as an analysis target, and calculates the weight coefficient of each work ID associated with the worker ID from the weight coefficient table 163. read out. Based on the following equation (1), the fatigue level determination unit 111 multiplies the weighting factor Wa _i read for each work ID by the required time T _i required for the work ID, and the multiplication result for each work ID. Get F _i . In the following formula (1), “i” is an identifier for identifying each work ID (1 to n: n is the number of work ID types).

Further, the fatigue level determination unit 111 adds all the multiplication results F _i obtained for the respective work contents based on the following formula (2), and acquires the addition result SF.

  When the fatigue level determination unit 111 reads the fatigue level value associated with the threshold range including the addition result SF from the fatigue level determination table 164, the fatigue level determination unit 111 works as the fatigue level of the worker ID targeted for processing. Registered in the person management table 161.

  Of the work IDs of the workers registered in the work history table 162, those with a predetermined period (for example, one week or one month) whose work date / time is recent are preferably processed. Further, in the present embodiment, the fatigue level is derived using the above formulas (1) and (2). However, the present invention is not limited to this, and the modified formulas of the above formulas (1) and (2) and others It is good also as a form derived | led-out using this type | formula. For example, in the above formula (1), a coefficient corresponding to the working hours (day shift, night shift, etc.) in which the work is performed may be further multiplied.

  The skill level determination unit 112 is a functional unit that derives the skill level for each type of work content to each worker based on the work content results of each worker registered in the work history table 162. Here, the skill level is a numerical value indicating the level of proficiency for each type of work content.

  Specifically, the skill level determination unit 112 sets each worker ID registered in the work history table 162 as an analysis target, and acquires the required time for each type of work ID associated with the worker ID. In addition, when the several required time is registered about the same work ID, it is good also as a form which acquires the minimum time or the maximum time among the required time, and calculates the average value of required time. It is good also as a form to acquire.

Further, the skill level determination unit 112 specifies, for each work content (work ID) type, the skill level for each task in the threshold range including the required time acquired for the work content type from the skill level determination table 165. . The skill level determination unit 112 adds all the job-specific skill levels SK _j specified for each type of work content based on the following formula (3), and the addition result is required to derive the job-specific skill levels SK _j . By dividing by the number of types of work contents, an average value SK of skill levels SK _j for each work is calculated. Then, when the skill level determination unit 112 determines the calculation result SK as the skill level of the worker ID to be analyzed, the skill level determination unit 112 associates the value with the worker ID to be analyzed and registers it in the worker management table 161. In the following formula (3), “j” is an identifier (1 to n: n is the number of types of work IDs) for identifying various types of work contents.

  Of the work IDs of the workers registered in the work history table 162, it is preferable that a predetermined period (for example, one week or one month) where the work date and time is the latest be the target of processing. In this embodiment, the average of the proficiency level for each work obtained for each type of work ID is set as the skill level of the worker. However, the present invention is not limited to this. It is good also as a form which makes a degree into a worker's skill level. In the present embodiment, the skill level is derived using the above equation (3). However, the present invention is not limited to this, and the degree of skill is derived using a modified equation of the above equation (3) or another equation. It is good also as a form.

  The work shift creation unit 113 creates a work shift for a predetermined period specified via the input unit 14 based on various conditions, and the created work shift is displayed in the display unit 15, the storage unit 16, and the communication I / O. This is a functional unit that outputs to F17 and the like.

  Specifically, the work shift creation unit 113 refers to the constraint condition table 167, reads out the continuous working conditions for each working time corresponding to the fatigue level of each worker registered in the worker management table 161, and performs the continuous work The condition is set to the first condition when assigning a work shift to each worker. The work shift creation unit 113 also sets the second skill when assigning a work shift to each worker so that the sum of the skill levels of each worker assigned to the same working time is equal to or greater than a predetermined threshold. Set the condition. Also. The work shift creation unit 113 sets the shift condition of each worker registered in the shift request table 166 as the third condition when assigning a work shift to each worker. Then, the work shift creation unit 113 creates a work shift that defines the working days and working hours of each worker in the designated period based on the first condition, the second condition, and the third condition.

  The work shift itself is created using publicly known / public mathematical programming software or publicly / publicly known techniques such as 0-1 integer programming. The priority order of the first condition, the second condition, and the third condition is not particularly limited. In addition, the conditions other than the first condition, the second condition, and the third condition (for example, the number of persons required for each day of work and the range in which the number of times each nurse works) are determined when creating a work shift. It is good also as a form added as conditions.

  The operation of the work shift creation support apparatus 10 will be described below with reference to FIGS. Here, FIG. 9 is a flowchart showing a procedure of work shift creation processing.

  First, when the work shift creation unit 113 receives the designation of the creation period to be created for the work shift, which is input from the operator of the work shift creation support apparatus 10 via the input unit 14, the fatigue degree determination unit 111 and The skill level determination unit 112 is controlled to derive the fatigue level and skill level of each worker registered in the worker management table 161 (step S11).

The fatigue level determination unit 111 executes a fatigue level determination process for determining the fatigue level of each worker in accordance with the control of the work shift creation unit 113 and registers the fatigue level in the worker management table 161 (step S12). Further, the skill level determination unit 112 executes skill level determination processing for determining the skill level of each worker in accordance with the control of the work shift creation unit 113, and registers the skill level in the worker management table 161 (step S13). . The fatigue level determination process and the skill level determination process will be described later.

  Subsequently, the work shift creation unit 113 refers to the constraint condition table 167 and reads the continuous work conditions for each work hour corresponding to the fatigue level of each worker registered in the worker management table 161, and then The condition is set to a first condition when assigning a work shift to each worker (step S14). Next, the work shift creation unit 113 sets the second condition when assigning a work shift to each worker so that the total skill level of each worker assigned to the same work time is equal to or greater than a predetermined threshold. (Step S15). Furthermore, the work shift creation unit 113 sets the shift condition of each worker registered in the shift request table 166 as a third condition when assigning a work shift to each worker (step S16).

  Subsequently, the work shift creation unit 113 creates a work shift that defines the working day and working hours of each worker in the specified period based on the first condition to the third condition set in steps S14 to S16. (Step S17). Then, the work shift creation unit 113 outputs the created work shift (step S18), and ends this process.

  Next, with reference to FIG. 10, the fatigue level determination process in step S12 in FIG. 9 will be described. The fatigue level determination unit 111 first acquires the number of types of worker IDs registered in the work history table 162 (step S21). Subsequently, the fatigue level determination unit 111 repeats the following steps S22 to S27 for each type of worker ID by the number of types of worker ID.

  In step S22, the fatigue level determination unit 111 acquires the number of work contents (work ID) associated with the worker ID to be processed from the work history table 162 (step S22). And the fatigue degree determination part 111 repeats the process of the following steps S23 and S24 for every work ID for work ID.

  The fatigue level determination unit 111 reads the weighting coefficient associated with the work ID to be processed from the weighting coefficient table 163 (step S23). Subsequently, the fatigue level determination unit 111 multiplies the weighting factor read in step S23 by the required time associated with the work ID to be processed based on the above equation (1) (step S24).

  When the fatigue determination unit 111 performs the processes in steps S23 and S24 on all the work IDs associated with the worker IDs to be processed, the fatigue degree determination unit 111 obtains each work ID based on the above formula (2). All the multiplication results are added (step S25). Subsequently, when the fatigue level determination unit 111 reads the fatigue level value associated with the threshold range including the addition result of step S25 from the fatigue level determination table 164 (step S26), the value is set as a processing target. The fatigue level of the worker ID is registered in the worker management table 161 (step S27).

  And if the fatigue level determination part 111 performs the process of said step S22-S27 with respect to all the worker IDs registered into the work history table 162, a process will be returned to the work shift creation process of FIG.

  Next, the skill level determination process in step S13 in FIG. 9 will be described with reference to FIG. The skill level determination unit 112 first acquires the number of types of worker IDs registered in the work history table 162 (step S31). Subsequently, the skill level determination unit 112 repeats the following steps S32 to S35 for each type of worker ID by the number of types of worker ID.

  In step S32, the skill level determination unit 112 acquires the number of types of the work ID associated with the worker ID to be processed from the work history table 162 (step S32). Then, the skill level determination unit 112 repeats the processing in step S33 below for each type of work ID.

  When the skill level determination unit 112 obtains the required time associated with the work ID from the work history table 162 for the type of the work ID to be processed, the skill level determination unit 112 determines the skill level by work of the threshold range including the required time. Then, it reads from the skill level determination table 165 (step S33). As described above, when a plurality of required times are registered for the same type of work content (work ID), the minimum required time or the maximum required time may be acquired. The average value may be obtained.

  When the skill level determination unit 112 performs the process of step S33 on all types of work IDs associated with the worker IDs to be processed, the skill level determination unit 112 sets each type of work ID based on the above equation (3). All of the read skill levels by work are added and divided by the number of work ID types (step S34). Subsequently, the skill level determination unit 112 registers the value of the division result in step S34 in the worker management table 161 as the skill level of the worker ID as a processing target (step S35).

  And if the skill level determination part 112 performs the process of said step S32-S35 with respect to all the worker IDs registered into the work history table 162, a process will be returned to the work shift creation process of FIG.
