Description

  The present disclosure relates to an information processing apparatus, an information processing method, and a program.

  In recent years, with respect to operations such as factories, hospitals, nursing homes, call centers, department stores, restaurants, etc., there are an increasing number of workplaces in which multiple workers work in shifts (early, late, day shift, night shift, etc.). In such workplace management, labor costs are high if there are many workers, and there is a risk of reducing user satisfaction and sales opportunity loss if there are few workers. The assigned work shift table is required.

  Generally, when the work shift table is in units of one month, the work shift table for the next month is created in advance by the middle or late of the previous month. Previously, the work shift table was created by the person in charge of the work shift table (work manager) taking into account the wishes of each worker, and adjusting so that all employees do not feel unfair It was done by handwriting. However, in recent years, a technique for automatically creating a work shift table using a computer has been developed.

  For example, Patent Document 1 below discloses a technique for creating a work shift table based on conditions desired by workers and the results of work shift tables created in the past.

  Further, in Patent Document 2 below, a technique for generating a staffing plan corresponding to production efficiency by generating a staffing plan based on productivity including a combination of a plurality of staffs with reference to an actual work log of the staff. Is disclosed.

  Patent Document 3 below also discloses a technique for extracting a shift assignment pattern for each worker from a past work shift table and efficiently creating a work shift table with high probability.

  However, even if the work shift table is created based on the required personnel plan and the worker's request, the created work shift table may become unfair among workers. For example, there may be unfair feelings such as “only the demands of some workers are reflected” and “the number of irregular shifts of late and early shifts and holiday work differ from other workers”. In addition, there is a background that work styles and ways of thinking have been diversified in recent years. For example, people have different demands for work styles, such as “a way of working that is as good as other workers as much as possible” and “you may have a lot of early and late numbers, but you want to take the desired holidays.” There is a case. For this reason, even if the working conditions determined by the employer and the demands of the workers are simply satisfied, the fairness among the workers is not necessarily satisfied.

  In such a situation, for example, the technique disclosed in Patent Document 1 inputs the desired date and time of each worker and works shifts so as to satisfy the desired date and time as much as possible. It is difficult to judge whether a table is fair. In addition, in the technique disclosed in Patent Document 3, since patterns of work styles that appear probabilistically in the past are prioritized, it does not necessarily satisfy the various work styles requested by each worker. In addition, it is difficult to judge whether it satisfies fairness.

  Therefore, the present invention has been made in view of the above problems, and the object of the present invention is to relatively compare requests among workers related to a work shift table (absolute numerical evaluation). It is an object of the present invention to provide a new and improved information processing apparatus, information processing method, and program capable of evaluating fairness among workers.

A creation unit that creates a work shift table based on the set of attribute information, and the degree that the work shift table created by the creation unit satisfies the request indicated by the attribute information registered by the registration unit, An information processing apparatus is provided that includes an evaluation unit that performs relative evaluation in relation to the work shift table created for the other workers, and an evaluation result generation unit that generates an evaluation result by the evaluation unit.

  The information processing apparatus further includes a constraint condition generation unit that generates a new constraint condition for satisfying the request indicated by the attribute information evaluated as not satisfied in the work shift table by the evaluation unit, The creation unit may create the work shift table based on the new constraint condition generated by the constraint condition generation unit.

  The information processing apparatus further includes a storage unit that stores the attribute information registered by the registration unit in the past and the work shift table created by the creation unit, and the evaluation unit is stored by the storage unit. Further, the relative evaluation may be performed on the past attribute information and the work shift table.

  The said registration part may register the relative request | requirement in the comparison with the other said worker as said attribute information.

  The attribute information may include a relative height in comparison of the number of times of work for each work style with other workers.

  The attribute information may include the degree to which the shift pattern matches the shift pattern of another worker.

<1. First Embodiment>
First, a configuration example of a work shift table creation system (information processing apparatus) according to the present embodiment will be described with reference to FIG.

[1-1. Example of work shift table creation system]
FIG. 1 is a block diagram showing a configuration of a work shift table creation system 1 according to the first embodiment. As shown in FIG. 1, the work shift table creation system 1 according to this embodiment includes a work request input unit 11, a work request storage unit 12, an evaluation condition input unit 13, an evaluation condition storage unit 14, a constraint condition input unit 15, There are a constraint condition storage unit 16, a work shift table creation unit 21, a work shift table storage unit 22, a work request evaluation unit 31, a work request evaluation output unit 32, a work request condition creation unit 33, and a work request condition storage unit.

(1) Work request input section 11
The work request input unit 11 has a function of receiving input from the user. For example, the work request input unit 11 is realized by a mouse, a keyboard, or the like. As the user, for example, an administrator who creates a work shift table, a worker who is a target of the work shift table, and the like can be considered.

  The work request input unit 11 according to the present embodiment has a function as a registration unit that registers attribute information of a request for work that a worker has. Specifically, the work request input unit 11 receives an input of a request for a worker's work style from one or more viewpoints (attributes), and registers attribute information indicating the input request. The request for work is an implicit request for the work shift table such as the preference and way of working of the worker, and attribute information from various viewpoints can be considered. As an example of attribute information, for example, the relative height in comparison with other workers of the number of work for each work style, such as late number and early number, as corresponding to the viewpoint of working hours preference . In addition, as an example of attribute information, ease of following a desired shift condition, which will be described later, can be considered as corresponding to the viewpoint of consideration for colleagues and the workplace.

  The work request input unit 11 registers relative requests in comparison with other workers as attribute information. For example, the work request input unit 11 wants to increase the “number of early numbers”, to decrease the “number of late numbers”, or to be the same as other employees as compared to other workers. Accept the request. If the attribute information is a relative request, evaluate whether the work shift table satisfies the attribute information, thereby evaluating whether fairness among workers is ensured in the work shift table. Is possible. When attribute information is a relative request, fairness among workers is ensured by creating a work shift table that satisfies this attribute information.

  The work request input unit 11 registers attribute information based on, for example, input to the input screen illustrated in FIG. FIG. 2 is a diagram showing an example of an attribute information input screen according to the present embodiment. As shown in FIG. 2, the input screen allows the worker to register his / her request for how to work from the viewpoint of, for example, “number of early turn”, “achievement ratio of desired shift”, and “pattern of vacation and work”. It is like that. Among these, for example, in the “number of early numbers”, as shown in FIG. 2, an input of a relative request, that is, the number of “early number” compared with other workers, is accepted. Note that the input method may be one that accepts input on the input screen, or may be one that reads a questionnaire sheet configured so that it can be described from the same viewpoint and converts it into data.

(2) Work request storage unit 12
The work request storage unit 12 is a part that records and reads data on a predetermined recording medium. The work request storage unit 12 is realized, for example, as an HDD (Hard Disc Drive). Of course, various recording media such as a solid-state memory such as a flash memory, a memory card incorporating a fixed memory, an optical disk, a magneto-optical disk, and a hologram memory are conceivable. It may be configured to be able to execute reading. The work request storage unit 12 according to the present embodiment has a function as a storage unit that stores attribute information registered by the work request input unit 11 in the past.

(3) Evaluation condition input unit 13
The constraint condition input unit 15 has a function of receiving input from the user, like the work request input unit 11. Specifically, the evaluation condition input unit 13 has a function of receiving an input of an evaluation condition that is used as an index for evaluating whether or not the created work shift table is good. As an example of the evaluation condition, for example, a matter such as “total working hours for one month for all workers is reduced” can be cited. Note that the evaluation condition can also be regarded as one of the constraint conditions described later.

(4) Evaluation condition storage unit 14
Similar to the work demand storage unit 12, the evaluation condition storage unit 14 has a function of recording and reading data on a predetermined recording medium. The evaluation condition storage unit 14 according to the present embodiment stores the evaluation condition input by the evaluation condition input unit 13. The evaluation conditions stored in the evaluation condition storage unit 14 can be changed by user input.

(5) Restriction condition input unit 15
The constraint condition input unit 15 has a function of receiving input from the user, like the work request input unit 11. Specifically, the constraint condition input unit 15 receives an input of a constraint condition. The constraint condition is one or a plurality of setting items that must be observed according to the work mode at the workplace, and is a condition that the work shift table should satisfy so as not to interfere with work. For example, the constraint condition may be a condition that defines the number of workers required for each time period in the work shift table creation target period. In addition, the constraint condition may be a condition according to a work pattern such as “Every worker does not set early morning work (early number) on the next day after night work (late number)”. In addition, the constraint condition may be a condition defined by a law, a work rule, or the like, such as a workable time (workable time) for each worker. Further, the constraint condition may be a condition indicating a desire (hereinafter, also referred to as a desired shift) associated with a date and time such as a holiday desired by a worker and a working time zone. Note that the set of set constraint conditions is desirably a work shift table that is all satisfied, but it may be allowed to have a constraint condition that is not satisfied. In the following, the work shift table creation target period is also simply referred to as a target period.

(6) Restriction condition storage unit 16
Like the work demand storage unit 12, the constraint condition storage unit 16 has a function of recording and reading data on a predetermined recording medium. The constraint condition storage unit 16 according to the present embodiment stores the constraint condition input by the constraint condition input unit 15. Here, Table 1 and Table 2 below show examples of constraint conditions stored by the constraint condition storage unit 16.

  “Strength of constraint” in the table is an index of how much this constraint condition should be observed. For example, “absolute” indicates that it is a constraint that must be obeyed. For example, “strong” other than “absolute” indicates that it is necessary to satisfy a stronger constraint. It is also good.

  Table 2 shows the desired shift, and “Rare holiday” in the table indicates that each worker wishes to take a day off. For example, “Mr. C” indicates that a holiday is desired on “4th”. Note that the constraint conditions stored in the constraint condition storage unit 16 can be changed by user input.

(7) Work shift table creation unit 21
The work shift table creation unit 21 has a function as a creation unit that creates a work shift table based on a set of constraint conditions and a set of desired attribute information regarding the work shift table. For example, the work shift table creation unit 21 creates a work shift table for the target period while performing evaluation using the constraint conditions stored in the constraint condition storage unit 16 and the attribute information stored in the work request storage unit 12. To do. Thereby, the work shift table creation unit 21 does not cause trouble in work, and can create a work shift table in accordance with a worker's request.

  The work shift table creating unit 21 performs an evaluation using the work request conditions created by the work request condition creating unit 33 described later as an example of the evaluation using the attribute information stored in the work request storage unit 12, A work shift table may be created. As will be described later, the work request condition created by the work request condition creating unit 33 is a condition for correcting to satisfy the request in the target period according to the degree to which the worker's request has not been satisfied in the past. . For this reason, the work shift table creation unit 21 can create a work shift table that can eliminate unfairness that the worker has felt in the past, and can achieve fairness among the workers. . The work shift table creation unit 21 may create a work shift table while performing further evaluation using the evaluation conditions stored in the evaluation condition storage unit 14.

(8) Work shift table storage unit 22
The work shift table storage unit 22 has a function of recording and reading data on a predetermined recording medium, similarly to the work request storage unit 12. The work shift table storage unit 22 according to the present embodiment has a function as a storage unit that stores the work shift table created by the work shift table creation unit 21 in the past. The work shift table created by the work shift table creation unit 21 may be corrected by user input. In this case, the work shift table storage unit 22 stores the corrected work shift table.

(9) Work request evaluation section 31
The work request evaluation unit 31 performs a relative evaluation on the degree to which the work shift table created by the work shift table creation unit 21 satisfies the demands of the worker in relation to the work shift table created for other workers. It has a function as an evaluation unit. Specifically, the work request evaluation unit 31 includes a request that the work shift table of each worker output from the work shift table creation unit 21 indicates the one or more attribute information registered by the work request input unit 11. The degree of satisfaction is evaluated relative to each worker in relation to other workers. For example, when “number of early numbers” is included in the attribute information, the work request evaluation unit 31 counts the number of early numbers set for each worker, and compares the degree of matching with the request indicated by the attribute information. evaluate. In addition, when the “desired shift achievement ratio” is included in the attribute information, the work request evaluation unit 31 determines the degree to which the desired shift input by the constraint condition input unit 15 is reflected in the created work shift table. Relative evaluation. In addition, when the number of shifts for each work style in one week is included in the attribute information, the work request evaluation unit 31 relatively evaluates the degree of coincidence with the number of shifts requested for each week.

  The work request evaluation unit 31 performs the above-described relative evaluation based on the attribute information registered in the past and the work shift table created in the past, which are stored in the work request storage unit 12 and the work shift table storage unit 22. Do. As a result, the work request evaluation unit 31 can evaluate how much the worker's request has been satisfied in the past and how much has not been satisfied. And the evaluation result by the work demand evaluation part 31 is used for the production | generation of the new constraint condition by the work demand condition preparation part 33 so that it may mention later. For this reason, the work request condition creation unit 33 can create a future work shift table based on the degree to which the demands of past workers are satisfied. For example, the work request condition creation unit 33 can create a constraint condition (work request condition) that can create a work shift table that satisfies the request more for a worker whose request has not been satisfied in the past. It becomes. Thereby, it becomes possible to eliminate the unfair feeling that the worker felt in the past by the future work shift table.

(10) Work request evaluation output unit 32
The work request evaluation output unit 32 has a function as an evaluation result generation unit that generates an evaluation result by the work request evaluation unit 31. Specifically, the work request evaluation output unit 32 edits the evaluation result by the work request evaluation unit 31 into a form that is easy to recognize. Since the evaluation result by the work request evaluation unit 31 is a result of relative evaluation in relation to other workers, the output by the work request evaluation output unit 32 allows the user to obtain fairness among workers in the work shift table. Can be evaluated.

  The evaluation result generated by the work demand evaluation output unit 32 can be output in various forms. For example, the work demand evaluation output unit 32 outputs the evaluation result as a graph as shown in FIG. FIG. 3 is a diagram illustrating an example of an evaluation result output screen according to the present embodiment. The graph shown in FIG. 3 is a format called a radar chart, and the user can visually recognize how much the worker's request is satisfied. In FIG. 3, the content actually allocated in the created work shift table and the request indicated by the attribute information for the employees A and D are expressed in a comparable manner on the same scale. Of course, the work demand evaluation output unit 32 can generate an evaluation result in an arbitrary form such as another graph such as a bar graph and a numerical value.

(11) Work request condition preparation part 33
The work request condition creation unit 33 generates a new constraint condition for satisfying the request indicated by the attribute information evaluated by the work request evaluation unit 31 as not satisfied in the created work shift table. It has a function as a part. The new constraint condition generated by the work request condition creating unit 33 is also referred to as work request condition. The work request condition generated by the work request condition creation unit 33 is stored in the work request condition storage unit 34 and is referred to by the work shift table creation unit 21 when the work shift table is generated.

  Specifically, the work request condition creation unit 33 compares the evaluation value evaluated for each requested attribute by the work request evaluation unit 31 with the value of the attribute information input by the work request input unit 11. Then, the work request condition creating unit 33 creates a work request condition to be reflected in the work shift table in order to correct the deviation based on the degree of deviation. For example, the work request condition creation unit 33 generates a constraint condition such that a work shift table that satisfies the request is created for a worker whose request has not been satisfied in the past. Thereby, the work shift table creation unit 21 can create a work shift table that can eliminate unfairness among workers.

(12) Work request condition storage unit 34
The work request condition storage unit 34 has a function of recording and reading data on a predetermined recording medium, similarly to the work request storage unit 12. The work request condition storage unit 34 according to the present embodiment has a function as a storage unit that stores the work request condition created by the work request condition creation unit 33. The work request conditions stored in the work request condition storage unit 34 can be changed by user input.

  The configuration example of the work shift table creation system 1 according to this embodiment has been described above. Then, with reference to FIG. 4 and FIG. 5, the operation | movement process of the work shift table production system 1 which concerns on this embodiment is demonstrated.

[1-2. Operation processing]
In order to simplify the description, the operation process will be described using a specific example. First, various setting items will be described.

  Work shift table creation period is 1 day (Sunday), 2 days (Monday), 3 days (Tuesday), ..., 8 days (Sunday) 8 days. 4 people, Mr., Mr. C and Mr. D. Also, it is assumed that there are three patterns of work patterns: “early number”, “normal”, and “late number”. Further, as an example, the constraint condition storage unit 16 “not assigns an early number after a late number to each worker (hereinafter also referred to as“ constraint condition 1 ”)” and “one month” shown in Table 1 above. The total working hours of each worker in (1) is set to 40 hours or less (hereinafter also referred to as “restriction condition 2”), “two consecutive weekday holidays (Saturdays and Sundays) are not assigned (hereinafter also referred to as“ restriction condition 3 ”) ”Is stored. Further, it is assumed that the constraint condition storage unit 16 stores a constraint condition (hereinafter also referred to as “constraint condition 4”) that defines the minimum number of workers for each day of work. Here, as an example, it is assumed that the constraint condition storage unit 16 stores the constraint condition 4 shown in Table 3 below.

  Further, it is assumed that the constraint condition storage unit 16 stores a constraint condition (hereinafter also referred to as “constraint condition 5”) indicating a desired shift that is a holiday or work time zone desired by the worker. Here, as an example, it is assumed that the constraint condition storage unit 16 stores the constraint condition 5 shown in Table 2 above.

  In addition, the evaluation condition storage unit 14 stores an evaluation condition that “the total working time for one month for all workers is reduced”.

  The contents stored in the evaluation condition storage unit 14 and the constraint condition storage unit 16 are input by the evaluation condition input unit 13 and the constraint condition input unit 15 before performing the work shift table creation process described below. It shall be. First, the work shift table creation process will be described with reference to FIG.

(Work shift table creation process)
FIG. 4 is a flowchart illustrating an example of a work shift table creation process executed in the work shift table creation system 1 according to the present embodiment. As shown in FIG. 4, first, in step S102, the work shift table creation system 1 acquires a constraint condition, an evaluation condition, and a work request condition. Specifically, the work shift table creation unit 21 refers to the constraint condition storage unit 16, the evaluation condition storage unit 14, and the work request condition storage unit 34, and acquires various conditions that the work shift table should satisfy.

  Next, in step S104, the work shift table creation system 1 initializes the work shift table. For example, the work shift table creation unit 21 initializes the work shift table by acquiring any past work shift table stored in the work shift table storage unit 22 or assigning a shift at random.

  Next, in step S106, the work shift table creation system 1 searches for a work shift table that satisfies the various conditions acquired in step S102. Specifically, the work shift table creation unit 21 evaluates whether or not the temporarily created work shift table satisfies the constraint condition and the work request condition. For example, the work shift table creation unit 21 evaluates whether the above-described constraint conditions 1 to 5 are satisfied. If not, the work shift table creation unit 21 repeats the evaluation while appropriately changing the contents of the work shift table.

  Furthermore, the work shift table creation unit 21 evaluates the work shift table using the evaluation conditions. The evaluation condition storage unit 14 stores an evaluation condition that “the total working time for one month for all workers is reduced”. For this reason, the work shift table creating unit 21 calculates the total working hours of all workers from the work shift table, and repeats the evaluation while appropriately changing the work shift table so that the total working time is reduced. Here, an example of working hours for each working mode is shown in Table 4 below. The work shift table creation unit 21 can calculate the total working hours by replacing all the work hours with “early number”, “normal”, and “late number” in the work shift table and adding them up.

  The evaluation regarding the constraint conditions by the work shift table creation unit 21 will be specifically described. As an example, it is assumed that the work shift table creation unit 21 temporarily creates a work shift table shown in Table 5 below.

  As shown in Table 5, “late number” is set as the shift of Mr. A on the first day (day). Since the restriction condition 1 prohibits the assignment of “early number” on the second day (Tue) of Mr. A, it is necessary to assign “normal” or “rest”. As shown in Table 5, since the shift on the second day (Tue) of Mr. A is “vacation”, the work shift table creation unit 21 evaluates that this work shift table satisfies the constraint condition 1.

  Further, according to the restriction condition 3, it is desirable that holidays are assigned to the 7th day (Sat) and the 8th day (Sunday) of “Mr. A”. As shown in Table 5, since “vacation” is assigned, the work shift table creation unit 21 evaluates that this work shift table satisfies the constraint condition 3.

  In addition, due to the restriction condition 4, it is required that at least one “normal” be assigned in addition to Mr. A's “late number” on the first day (day). As shown in Table 5, since “normal” is assigned to Mr. C, the work shift table creation unit 21 evaluates that this work shift table satisfies the constraint condition 4.

  In addition, due to the constraint condition 2, the total working hours of each worker is required to be 40 hours or less. Table 6 below shows the total working hours calculated by replacing “early number”, “normal”, and “late number” in the work shift table shown in Table 5 with the work hours shown in Table 4 above. As shown in Table 6, since all working hours of A to D are 40 hours or less, the work shift table creation unit 21 evaluates that this work shift table satisfies the constraint 2 To do.

  In addition, due to the constraint 5, it is required that “rest” is assigned to the fourth day (Wednesday) and the eighth day (Sunday) of Mr. C and the fifth day (Thursday) of Mr. D. As shown in Table 5, since “off” is assigned on the desired day, the work shift table creation unit 21 evaluates that this work shift table satisfies the constraint condition 5.

  Then, the evaluation regarding the evaluation conditions by the work shift table creation unit 21 will be specifically described. As an example, in addition to the work shift table shown in Table 5 above, the work shift table creation unit 21 temporarily creates the work shift table shown in Table 7 below.

  Table 5 and Table 7 differ only in the shift of Mr. D on the first day (day). The work shift table creation unit 21 evaluates which of these work shift tables should be selected based on the evaluation conditions. The first day (day) of Mr. D is “absence” in Table 5 and “normal” in Table 7. Therefore, referring to the working hours shown in Table 4, Table 7 is a total compared to Table 5. The working hours will be 7 hours more. Even if the work shift tables shown in Tables 5 and 7 satisfy all the constraints, the evaluation condition that “the total working hours for all workers for one month is reduced” The work shift table shown in is evaluated as better.

  As described above, the work shift table creation unit 21 searches for a better work shift table based on various conditions. Note that the work shift table creation unit 21 may perform this search using an optimization algorithm such as a genetic algorithm and an annealing method. Hereinafter, the description returns to the flowchart.

  Next, in step S108, the work shift table creation system 1 outputs a work shift table. Specifically, the work shift table creation unit 21 outputs the work shift table searched in step S106 using various output devices. For example, the work shift table is displayed on the display device. The work shift table may be corrected by user input. Then, the work shift table creation system 1 may store the corrected work shift table and output a sheet on which the work shift table is printed by a printer (not shown).

  The work shift table creation process according to the present embodiment has been described above.

  The work shift table creation system 1 evaluates to what extent the work shift table created in the past satisfies the demands of the worker, and creates work request conditions to be reflected in the work shift table in order to correct the deviation. . In the following, the work shift table evaluation process and the work request condition creation process will be described with reference to FIG.

(Work shift table evaluation process and work request condition creation process)
FIG. 5 is a flowchart showing an example of the flow of work shift table evaluation processing and work request condition creation processing executed in the work shift table creation system 1 according to the present embodiment. As shown in FIG. 5, first, in step S <b> 202, the work shift table creation system 1 evaluates whether or not the work shift table satisfies a worker's request. Specifically, the work request evaluation unit 31 refers to the work request storage unit 12 and the work shift table storage unit 22 to determine the degree to which the past work shift table satisfies the request indicated by the attribute information for other workers. Relative evaluation is made in relation to the created work shift table.

  Hereinafter, the evaluation regarding the attribute information by the work request evaluation unit 31 will be specifically described. It is assumed that the work shift table storage unit 22 stores the work shift table created in the past and shown in Table 5 above. It is assumed that the work request storage unit 12 stores attribute information shown in Table 8 below.

  First, the work request evaluation unit 31 acquires one or more past work shift tables stored in the work shift table storage unit 22 and attribute information stored in the work request storage unit 12. Here, it is assumed that the work request evaluation unit 31 acquires the work shift table shown in Table 5 and the attribute information shown in Table 8 above.

  Next, the work request evaluation unit 31 refers to the shift of each worker assigned to the acquired past work shift table and calculates an evaluation value for each attribute. As an example, an example of calculating an evaluation value for “number of early numbers” will be described.

  First, the work request evaluation unit 31 obtains a difference between the average number of times of “early turn” of all workers and the number of hours of work of “early turn” of each worker. For example, if the average number of work of “early number” of all workers is 15 and the number of work of “early number” of “Mr. A” is 14, the difference is 14−15 = −1. On the other hand, for example, when the number of working hours of “Mr. C” is “20”, the difference is 20−15 = 5. Then, the work demand evaluation unit 31 quantizes the minimum and maximum value ranges of the difference values thus obtained, and reassigns the respective difference values to the quantized values. For example, in the example shown in FIG. 2, for “the number of early numbers”, since the request is accepted between 0 and 10, the work request evaluation unit 31 assigns the difference values to values of 0 to 10, respectively. cure. This assigned value is also referred to as an evaluation value below.

  As an example of the quantization method, a method that divides the range between the minimum value and 0 into 5 steps and the range between 0 and the maximum value into 5 steps is adopted. For example, when the minimum value is -1 and the maximum value is 5, the work demand evaluation unit 31 divides -1 to 0 into 5 levels and 0 to 5 into 5 levels (-1, -0.8, -0.6, -0.4, -0.2, 0, 1, 2, 3, 4, 5), replace the difference value with the closest of these divided values. Then, the work request evaluation unit 31 evaluates the values from −1 to 5 to 0 to 10 with −1 being 0, −0.8 being 1 and −0.6 being 2, among the replaced values. Replace with a value. In this way, quantization is performed. The “number of late numbers”, “number of holiday attendances”, and “approved shift approval ratio” shown in FIG. 2 may also be quantized by the same method.

  As another example of the quantization method, for example, the larger one of the minimum value and the maximum value is selected, and if the absolute value of the maximum value is larger, the minimum value is set as a negative value of the maximum value. When the absolute value of the minimum value is larger, a method may be used in which the maximum value is set as a negative value of the minimum value, the value range is reset, and the value range is divided into 10 at equal intervals. For example, when the minimum value is -1 and the maximum value is 5, since the absolute value is larger than the maximum value, the work demand evaluation unit 31 sets the minimum value to a negative value -5 of the maximum value, and -5 to 5 Is divided into 10 (-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5), and the difference value is replaced with the one with a close value. Then, the work request evaluation unit 31 sets, for example, −5 to 0, −4 to 1 and −3 to 2, and the difference value from −5 to 5 to the evaluation value from 0 to 10 among the replaced values. replace.

  Next, an example of the quantization method for the “desired one week shift” shown in FIG. 2 will be described. First, the work request evaluation unit 31 calculates the average of the number of appearances per week for each work style (“early number”, “normal”, “late number”) recorded in the past work shift table. For example, regarding the work shift table for the past two weeks, if the number of early turns is “2” for the first week and “3” for the second week, the average is (2 + 3) /2=2.5 (times ) Then, the work request evaluation unit 31 calculates the average value for all workers in this way, quantizes the range of the minimum value and the maximum value for all workers, and replaces each average value with the evaluation value. Since this method is as described above, a detailed description thereof is omitted here.

  Note that these evaluation value calculation methods are merely examples, and the technology according to the present invention is not limited to these examples. For example, when calculating the average, give a weight to the value closest to the present in the past work shift table with a large weight, and conversely, give a weighted average to the value moving away from the current by gradually decreasing the weight. A method is conceivable.

  The evaluation process by the work demand evaluation unit 31 has been described above. Hereinafter, the description returns to the flowchart.

  Next, in step S204, the work shift table creation system 1 outputs the evaluation result in step S202. Specifically, the work demand evaluation output unit 32 outputs, for example, the radar chart shown in FIG. 3 to the display device or outputs the paper printed by the printer.

  In step S206, the work shift table creation system 1 creates work requirement conditions based on the evaluation result in step S202. Specifically, the work request condition creation unit 33 first compares the evaluation value for each attribute calculated by the work request evaluation unit 31 with the value of the attribute information input by the work request input unit 11. Then, the work request condition creating unit 33 creates a work request condition to be reflected in the work shift table in order to correct the deviation based on the degree of deviation. Various methods can be considered for comparing the evaluation value and the attribute information value and for creating the work request condition. For example, the work request condition creation unit 33 subtracts the evaluation value from the value of the attribute information, and creates a corresponding work request attribute condition when the difference is equal to or greater than a threshold value.

  For example, the threshold value regarding the attribute “number of late numbers” is set to “4”, the evaluation value of “number of late numbers” of “D” is set to “3”, and the “late number of late numbers” requested by Mr. D stored in the work request storage unit 12 is requested. The value of “number” is “10”. The absolute value of the value obtained by subtracting the evaluation value “3” from the work attribute value “10” is “7”, and the sign is “positive”. In this case, the work request condition creating unit 33 creates a work request condition of “setting the number of Mr. D's late number to be greater (positively) than the number corresponding to the evaluation value“ 7 ””. When the sign is “negative”, the work request condition creating unit 33 “sets the number of Mr. D's late number to be less (negative) than the number corresponding to the evaluation value“ 7 ””. Create

  The number of late numbers corresponding to the evaluation value “7” is obtained in the same manner as the evaluation process by the work demand evaluation unit 31. For example, the evaluation value “0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10” of “the number of late numbers” is a specific numerical value “−5, − Assume a case corresponding to “4, −3, −2, −1, 0, +1, +2, +3, +4, +5”. In this case, since the number of late numbers corresponding to the evaluation value “7” is “+3”, the number of late numbers of Mr. D is “+3” in the average value “7” of the “number of late numbers” of all workers. The sum is “10”. As a result, the work request condition creating unit 33 creates a work request condition of “setting the number of Mr. D's late number to be greater than 10” as shown in Table 9 below.

  The work request condition creating process by the work request condition creating unit 33 has been described above. Hereinafter, the description returns to the flowchart.

  Next, in step S208, the work shift table creation system 1 stores the work request conditions created in step S206. Specifically, the work request condition storage unit 34 stores the work request condition created by the work request condition creation unit 33. At this time, when the work request condition related to the same attribute is already stored, the work request condition storage unit 34 deletes the existing one and stores the newly created work request condition.

  As described above, the work shift table creation unit 21 creates a work shift table while evaluating whether or not the work request conditions stored in the work request condition storage unit 34 are satisfied. For this reason, for example, when the work request condition storage unit 34 stores the work request conditions shown in Table 9 above, the work shift table creation unit 21 sets the number of Mr. D's late number to be greater than 10 times. Will be made a work shift table.

  The work shift table evaluation process and the work request condition creation process according to the present embodiment have been described above.

  According to the present embodiment, the work shift table creation system 1 can generate an evaluation result indicating how much the created work shift table satisfies a worker's request. The degree of achievement of various requests can be grasped. Furthermore, since this evaluation result is a result of relative evaluation in relation to other workers, the user can evaluate the fairness among workers in the work shift table.

  Also, the work shift table creation system 1 can create a work shift table that satisfies various demands on the working style of the worker by using the worker's request as a work request condition as an evaluation index. Since this work request condition is created as a result of relative evaluation, the work shift table reflecting the work request condition can alleviate unfairness among workers with respect to the work shift table.

<2. Second Embodiment>
In the present embodiment, “the generality of the shift pattern” is adopted as the attribute information. First, a configuration example of the work shift table creation system 1 according to the present embodiment will be described with reference to FIG.

[2-1. Example of work shift table creation system]
FIG. 6 is a block diagram illustrating a configuration of the work shift table creation system 1 according to the second embodiment. As shown in FIG. 6, the work shift table creation system 1 according to the present embodiment includes a shift pattern frequency statistics unit 23 and a shift pattern frequency in addition to the configuration according to the first embodiment described with reference to FIG. 1. A storage unit 24 is included.

(1) Shift pattern frequency statistics unit 23
The shift pattern frequency statistics unit 23 has a function of referring to the work shift table stored in the work shift table storage unit 22 and extracting the shift pattern in the unit period of each worker and obtaining the frequency. The shift pattern refers to a shift allocation pattern such as “first day is early, second day is late, third day is late,...”. For example, the shift pattern frequency statistic unit 23 extracts shift patterns on a weekly basis, and obtains the frequency for each extracted shift pattern.

(2) Shift pattern frequency storage unit 24
The shift pattern frequency storage unit 24 has a function of recording and reading data on a predetermined recording medium, like the work request storage unit 12. The shift pattern frequency storage unit 24 according to the present embodiment stores the shift pattern extracted by the shift pattern frequency statistics unit 23 and its frequency.

(3) Others The work request input unit 11 according to the present embodiment accepts an input of “generality of shift pattern” as attribute information. The generality of the shift pattern indicates the degree to which the shift pattern matches the shift pattern of another worker. The work request storage unit 12 can store “generality of shift pattern” as attribute information. In this case, the work request evaluation unit 31 searches the shift pattern frequency storage unit 24 for a shift pattern included in the work shift table, and evaluates the “shift pattern generality” based on the frequency of the matching shift pattern. Further, the work request condition creating unit 33 compares the evaluation value related to the “shift pattern generality” with the worker's request, and sets the work request condition for increasing or decreasing the “shift pattern generality”. create.

  The configuration of the work shift table creation system 1 according to the present embodiment has been described above. Subsequently, an operation process according to the present embodiment will be described with reference to FIG. In the following, a work shift table evaluation process related to “generality of shift pattern” characteristic of this embodiment will be described.

[2-2. Operation processing]
FIG. 7 is a flowchart illustrating an example of the flow of work shift table evaluation processing executed in the work shift table creation system 1 according to the present embodiment. As shown in FIG. 7, first, in step S302, the work shift table creation system 1 calculates the frequency for each shift pattern. Specifically, the shift pattern frequency statistics unit 23 refers to the past work shift table stored in the work shift table storage unit 22 to extract the shift pattern in the unit period of each worker and obtains the frequency.

  For example, it is assumed that the unit period for detecting the shift pattern is one week, and the work shift table shown in Table 10 below is stored in the work shift table storage unit 22.

  Here, “late, normal, normal, early, normal, rest, rest” is referred to as shift pattern A, and “normal, early, normal, rest, early, early, normal” is also referred to as shift pattern B. As shown in Table 10 above, Mr. A's shift pattern from the second day (month) to the eighth day (sun), Mr. B's shift pattern from the second day (month) to the eighth day (sun), The shift pattern from the first day (Sunday) to the seventh day (Saturday) of Mr. and D is the shift pattern A. For this reason, the frequency of the shift pattern A is “3”. On the other hand, the shift pattern from the first day (Sunday) to the seventh day (Saturday) of Mr. C is the shift pattern B. For this reason, the frequency of the shift pattern B is “1”.

  The shift pattern frequency storage unit 24 stores the shift pattern and the frequency extracted from the past work shift table in this way.

  Next, in step S304, the work request evaluation unit 31 detects a shift pattern from the work shift table created by the work shift table creation unit 21. The operation here is as described above in step S302.

  In step S <b> 306, the work shift table creation system 1 evaluates “the generality of the shift pattern” of the work shift table created by the work shift table creation unit 21. Specifically, the work request evaluation unit 31 searches the shift pattern frequency storage unit 24 for a shift pattern included in the work shift table, and evaluates “the generality of the shift pattern” based on the frequency of the matching shift pattern.

  For example, an example will be described in which the work request evaluation unit 31 evaluates the work shift table shown in Table 5 above. In the work shift table shown in Table 5, the shift pattern A described above is detected as a shift pattern from the second day (month) to the eighth day (day) of Mr. B. Further, the shift pattern B described above is detected in the shift pattern from the first day (Sunday) to the seventh day (Saturday) of Mr. C. On the other hand, none of the shift patterns A and B stored in the shift pattern frequency storage unit 24 is detected from the shift shift table of Mr. A and Mr. D.

  When a shift pattern with a high frequency stored in the shift pattern frequency storage unit 24 is detected like Mr. B, Mr. B's work shift table is evaluated to have a high “generality of shift pattern”. On the other hand, when a shift pattern stored in the shift pattern frequency storage unit 24 is not detected like Mr. A and Mr. D, or a shift pattern with a low frequency is detected like Mr. C, the work shift table Is evaluated as having a low “generality of shift pattern”.

  The work shift table evaluation process according to the present embodiment has been described above.

  According to the present embodiment, it is possible to evaluate the work shift table with respect to the generality of the shift pattern and create a work shift table for satisfying the worker's request. For this reason, it is possible to evaluate whether each worker's work style is similar to other workers according to the worker's request, such as wanting to work in a way similar to other workers, for example. It becomes. Furthermore, the work shift table creation system 1 can create a work shift table including a large number of general shift patterns in response to such a request. Thereby, shift patterns of workers are similar to each other, and fairness among workers is increased.
