Description

Application of Article 30, Paragraph 2 of the Patent Law Announced through telecommunications lines on January 20, 2021 (published address: https://hospi.ai).

The present invention relates to a scheduling system, a scheduling program, and a scheduling method that allocate multiple resources to multiple tasks and create a schedule for a predetermined period.

Conventionally, creating schedules has been a heavy burden for administrators of companies and the like. For example, when creating shifts (one aspect of a schedule) for workers, it is necessary to solicit the wishes of the workers and then allocate the shifts so as to meet the wishes as much as possible. In addition, if there are restrictions on allocating shifts according to the attributes of workers, that is, job titles, qualifications, skill levels, etc., a huge number of mathematical combinations will be required, which is a barrier to manual work by humans. It was. Specifically, there are shifts that can only be assigned to specific workers, shifts must be assigned in a specific combination during the same time period, and two specific types of shifts must not be assigned consecutively. As the constraints on creating shifts increase, such as having to do so, it becomes more difficult to create shifts.

In view of this situation, for example, in Patent Document 1, essential conditions that must be satisfied when determining a schedule and desired conditions that are preferable conditions to be satisfied when determining a schedule are set. By doing so, a technique of a shift determination device is disclosed that searches for an optimum shift solution that satisfies the essential conditions while increasing the degree of satisfying the desired conditions.

JP 2019-101551 A

However, the technology of the scheduling system disclosed in Patent Document 1 requires mathematical knowledge and programming knowledge to set constraints (essential conditions and desired conditions) in creating a schedule. Users without specialized knowledge had no choice but to ask experts such as programmers to set them.

In addition, the scheduling system created as described above is a uniform scheduling system that can be used only for specific scheduling, without being able to easily change the setting of constraints. Therefore, for example, even if the user is the same, there is a problem that different types of schedules (for example, schedules for different tasks or different stores) cannot be created by the scheduling system (versatility is low). rice field. In addition, there is a problem that if the constraints on creating a schedule change, the scheduling system cannot be used without changing the settings of the constraints. Needless to say, changing the settings in such a case also requires specialized knowledge, so there is no choice but to ask an expert to make the settings.

Due to this situation, in order to use the conventional scheduling system, specialized knowledge is essential. I had to give up using the scheduling system.

The present invention has been made in view of such conventional circumstances. One object of the present invention is to provide a general-purpose scheduling system, scheduling program and scheduling method that can be easily used by users who do not have knowledge of mathematics or programming.

<Schedule creating unit 134>

The schedule creation unit 134 is a member that creates shifts based on resource-specific data, resource attribute data, task data, and constraint data, and has a preprocessing unit 1341 , a calculation processing unit 1342 and a schedule display processing unit 1343 .
<<Pre-processing unit 1341>>

The preprocessing unit 1341 is a member that creates calculation data used in calculation processing for the calculation processing unit 1342 to create shifts, based on resource unique data, resource attribute data, task data, and constraint data. Calculation data includes, for example, an objective function that functionally expresses the purpose of the scheduling system 1 to "create an optimum shift," and a constraint expression that expresses constraint data in a mathematical formula. The program code is rewritten so that the unit 1342 can process it.

In addition, when the learning unit 136, which will be described later, has created a first learning model, the preprocessing unit 1341 can also create calculation data based on the first learning model. In this case, the first learning model is processed, for example, as one of the constraint data.
<<calculation processing unit 1342>>

The calculation processing unit 1342 performs calculation processing using the calculation data created by the preprocessing unit 1341, and converts shift data (corresponding to an example of “schedule data” in the scope of claims) that is data related to shifts. This is a member to be created in multiple numbers. For example, by causing software called Google OR-Tools (Google LLC) to execute the program code created by the pre-processing unit 1341, a plurality of shift data can be created.

Further, the calculation processing unit 1342 ranks the plurality of shift data based on the constraints satisfied by each of the plurality of shift data and the priority of the constraint (corresponding to an example of the “ranking unit” in the scope of claims). do.). Specifically, in descending order of priority, shift data created by satisfying more constraints is given the highest priority as optimum shift data. Furthermore, when the later-described learning unit 136 creates a second learning model, the calculation processing unit 1342 can also rank the plurality of shift data based on the second learning model.
<<Schedule display processing unit 1343>>

The schedule display processing unit 1344 is a member that creates a shift image from the shift data created by the calculation processing unit 1342 so that the user can check the created shift on the website. All users can check the created shift image.

The schedule display processing unit 1344 has (1) a function of creating a shift image using the shift data given the highest rank in the calculation processing unit 1342 so that the user can view only the optimum shift; (2) It has a function of creating a shift image using several pieces of shift data with the highest order, and allowing the user to select and use the most preferred shift from among them. These functions are switchable, and the user can select the desired function.

Also, when the function (2) is used, one schedule selected by the user is stored (corresponding to an example of the "fourth storage processing section" in the scope of claims). This is because the memory is used by the learning unit 136 (details will be described later).

Note that the schedule display processing unit 1344 is not particularly limited as long as it can create a shift image from at least one piece of shift data. Also, the mode of the shift image is not particularly limited.
<Schedule correction unit 135>

The schedule correction unit 135 is a member that corrects the shifts created by the schedule creation unit 134 based on user instructions.

The schedule can be modified on the website by (1) the administrator AD operating the second terminal 12 and instructing the desired modification, and (2) the worker WO operating the first terminal 11 and performing other operations. There is a method of requesting a worker WO to change shifts. Regardless of which method is used, the shift image is recreated by reflecting the correction performed by the schedule display processing unit 1343 . All users can check the created shift image.

Note that the mode of the schedule display processing unit 1344 is not limited to the above.
<Learning unit 136>

The learning unit 136 (corresponding to an example of the “first learning unit” and “second learning unit” in the claims) is a member that converts the knowledge and experience obtained by creating shifts into data, The scheduling system 1 uses the data when creating shifts from the next time onward. Thereby, the precision of shift creation can be improved each time a shift is created.

The learning unit 136 has two methods for converting the knowledge and experience obtained by creating shifts into data. The first method is to learn the schedule desired by the user from the shifts created by the schedule creation unit 134 and the shifts corrected by the schedule correction unit 135, and store the knowledge and experience obtained by the learning as data. It is a method of creating a first learning model that is transformed into. As a result, the preprocessing unit 1341 can create calculation data also based on the first learning model, and when creating shifts from the next time onward, it is possible to create shifts desired by the user with higher accuracy. can.

Second, when the function (2) of the schedule display processing unit 1343 is used, the shift that the calculation processing unit 1342 ranks highest and the one schedule selected by the user selects the shift that the user desires. This is a method of learning a schedule and creating a second learning model by converting the knowledge and experience obtained by the learning into data. As a result, the calculation processing unit 1342 can rank a plurality of shift data based on the second learning model as well, and when creating shifts from the next time onward, the shift desired by the user can be given a higher rank with higher accuracy. can be attached.

If the resource-specific data, resource attribute data, task data, and constraint data are set, the schedule creation step ST04 can be executed. The order in which ST03 is performed can be changed as appropriate, and each step may be performed multiple times. Furthermore, if resource-specific data, resource attribute data, task data, and constraint data are set in advance, the first storage processing step ST01, the second storage processing step ST02, and the third storage processing step ST03 Implementation can be omitted.
