Description

Technical Field

[0001] This invention relates to a schedule management system and a schedule management method. Background Technology

[0002] In recent years, people have been implementing an autologous cell transplantation technique that involves collecting cells from a patient's body, culturing them, and transplanting them back into the patient's body. This requires schedule management of a series of steps.

[0003] Japanese Patent Application Publication No. 2021-22409 (Patent Document 1) discloses a technology concerning a schedule planning calculation device: "The control unit of the order management server (schedule planning calculation device) includes a receiving unit, a schedule calculation unit, and a calendar screen generation unit. The receiving unit receives data on the dosing date of a drug from a client terminal (user terminal) installed in a medical facility, which is specified by the user for the calendar screen data of each user displayed on the client terminal (user terminal). The schedule calculation unit calculates each implementation day for implementing multiple steps related to delivery from the collection date to the dosing date based on the dosing date data received by the receiving unit. The calendar screen generation unit generates calendar screen data including each implementation day from the collection date to the dosing date."

[0006] Patent Document 1: Japanese Patent Application Publication No. 2021-22409 Summary of the Invention

[0007] The technical problem that the invention aims to solve

[0008] In managing the schedule of a series of steps (processes) involving multiple facilities, in order to develop an implementable schedule, it is necessary to confirm each time, based on the business intervals between steps, whether the schedule of the facilities responsible for that step and related steps can be guaranteed, making schedule management very difficult.

[0009] In addition, with the multiple facilities involved each having a high degree of independence, the information that each facility can provide to the other facilities is limited, which makes it difficult to adjust the schedule.

[0010] In scheduling management of a series of steps that may involve multiple facilities, it is necessary to confirm the schedules of all facilities responsible for the relevant steps, and there may be constraints—such as limitations in information exchange. Therefore, it is difficult to automatically adjust the schedule and allocate resources based on the resources of all candidate facilities.

[0011] Technical means to solve the problem

[0012] One representative example of the scheduling management system and scheduling management method of the present invention includes: a storage unit that stores resource data and coordination rules for a chain of multiple services related to supply; and a control unit that performs scheduling management of the services with reference to the resource data and the coordination rules, wherein the resource data is data that manages the idle status of resources used by facilities performing the services when executing the services, and the coordination rules are rules that define the sequential relationship of the services and represent the service intervals between the facilities; the control unit determines the services that form the chain based on the sequential relationship of the services, determines the facilities capable of executing the determined services, and provides information on whether the supply can be reserved by referring to the idle status of the resources of the determined facilities.

[0013] Invention Effects

[0014] It is able to appropriately implement schedule management for multiple cases involving multiple facilities. Attached Figure Description

[0027] The following description uses the accompanying drawings to illustrate the embodiments.

[0028] [Example 1]

[0029] Figure 1 This is a schematic diagram of the resource management function of an embodiment. In this embodiment, the scheduling adjustment function in a system that manages the business chain, i.e., the supply chain, related to supply (supply) – especially the supply chain of products such as regenerative medicine – is illustrated as an example.

[0030] Figure 1 The largest boxes within represent stakeholders operating the system; "Manufacturing Plant A" and "Medical Institution X" correspond to these. Stakeholders function as facilities or tenants, performing a specific task within the supply-related business chain. Furthermore, "Room 1" and "Room 2" within "Manufacturing Plant A" are smaller resource management units within each stakeholder. Additionally, "Unit Resource" represents the resources held by each stakeholder for each resource unit, and "Reservation Instance" represents resources secured (reserved) through reservation. A "Reservation Instance" may have more than one "Unit Resource." The horizontal direction is along the time axis, with the rightward direction representing the future.

[0031] The system of this invention can manage, through resource management functions, which stakeholders' unit resources are guaranteed (reserved) for which case and which service. For example, consider medical institution X, which has two appointment instances: one reserving resources for the apheresis (blood component collection) service of case ID001. Similarly, resources are reserved for the drug administration service of case ID002. Furthermore, the appointment instance for the apheresis service of case ID001 is to the left of the appointment instance for the drug administration service of case ID002, indicating that the apheresis service of case ID001 is the first service performed. This timing relationship also applies across stakeholders, indicating that wholesaler P's specimen transport service for case ID001 is performed after medical institution X's apheresis service for case ID001.

[0032] Figure 2 This is a schematic diagram of the schedule management function in the embodiment. Figure 2 The largest box within the box represents the case; "Case ID: 001" and "Case ID: 002" correspond to this. Figure 1Similarly, "unit resource" refers to the resource held by each stakeholder for each unit of resource, and "reservation instance" refers to the resource secured (reserved) through reservation. Additionally, the horizontal direction is along the time axis.

[0033] Figure 2 and Figure 1 The difference lies in the function of managing the implementation of business on a case-by-case basis. This indicates that case ID001 has reserved resources for single-sample collection, specimen transportation, and manufacturing operations, and the case is processed in the order of single-sample collection, specimen transportation, and manufacturing.

[0034] Figure 3 This is the system architecture diagram required to achieve this function. Figure 3 The largest box represents computer 10, which indicates that computer 10 contains "IF (interface) section 21", "control section 22" and "storage section 23".

[0035] IF section 21 is the part that connects computer 10 to user operation.

[0036] Control unit 22 is the part that controls the data input to or output to IF unit 21. Control unit 22 includes "Model Definition Unit 31", "Resource Definition Unit 32", "Reservation Category Definition Unit 33", "Target Reservation Category Mapping Definition Unit 34", "Model Reservation Category Mapping Definition Unit 35", "Coordination Rule Definition Unit 37", "Reservable Time Slot Control Unit 41", "Reservation Generation Unit 42", "Reservation Cancellation Unit 43", and "Business Progress Management Unit 44". Furthermore, only the parts relevant to this use case will be described here.

[0037] The model definition unit 31 defines the business model of this system and stores the defined data as model data 51 in the storage unit 23 for management.

[0038] The resource definition unit 32 defines the resources of each stakeholder and stores the defined data in the storage unit 23 as partition / subpartition data 52 (data representing the collection of resources of each lessee) and target data 53 (data representing the resources of the reservation object).

[0039] The appointment category definition department 33 generates appointment categories for each case and stakeholder, which are then stored in the storage department 23 as appointment category data 54 for management.

[0040] The target reservation category mapping definition unit 34 defines the reservation category associated with the target and stores its data as target reservation category mapping data 55 in the storage unit 23 for management.

[0041] The model reservation category mapping definition unit 35 defines the reservation categories associated with the models representing the business chain, and stores their data as model reservation category mapping data 56 in the storage unit 23 for management.

[0042] The coordination rule definition unit 37 defines the coordination rules for the reservation and stores its data as coordination rule data 57 in the storage unit 23 for management.

[0043] The reservation time slot control unit 41 controls the reservation time slots, the reservation generation unit 42 generates reservations, and the reservation cancellation unit 43 cancels reservations.

[0044] The Business Progress Management Department 44 manages the business progress status and stores the managed data as Business Progress Data 61 in the Storage Department 23 for management.

[0045] In addition to the various data mentioned above, the storage unit 23 also stores unit resource data 58 (data obtained by storing the units of resources), reservation data 59 (data obtained by storing the reservation status), and case data 60 (data obtained by storing the content of the case).

[0046] Reference Figures 4-6 Explain the coordination rule data. Figure 4 This is an explanatory diagram illustrating the object definitions for inter-resource coordination. Figure 5 This is a definition example of coordination rule data 57. Figure 6 This is a definition example of target appointment category mapping data 55.

[0047] Figure 4 In this context, the business "Specimen Collection" of "Hospital Tenant Y, Doctor Ichiro" and the business "Manufacturing" of "Manufacturing Plant Tenant X, Room 1" form a chain. In these two businesses, "Manufacturing" is the coordination origin, and "Specimen Collection" is the coordination destination. That is, when making an appointment, a reservation instance for the coordination origin, "Manufacturing," is generated first, followed by a reservation instance for the coordination destination, "Specimen Collection." The coordination direction indicates the temporal order of the coordination origin and destination, and the coordination interval indicates the time interval between the two businesses. The coordination destination start point and coordination origin start point indicate whether the specified coordination interval is at the beginning or end of the business. The data defining these relationships is coordination rule data 57.

[0048] like Figure 6 As shown, the target appointment category mapping data 55 maps the target to the appointment category. Figure 6 In this context, the target ID is associated with the target name and the reservation category.

[0049] Harmonization rule data 57 specifies the sequential relationships between multiple business chains (business chains) related to the supply of products such as regenerative medicine. Here, for example... Figure 5As shown, the coordination origin and coordination destination of the coordination rule are defined using "reservation category". Specifically, a coordination rule includes data such as rule ID, rule name, coordination origin reservation category, coordination destination reservation category, coordination interval, coordination direction, coordination origin starting point, and coordination destination starting point.

[0050] By reference Figure 5 The coordination rule data 57 shown can determine "which target (which lessee)'s resources should be processed".

[0051] Additionally, the target reservation category mapping data 55 is used to select between the time-slot-specific reservation mode and the flexible reservation mode, which will be described later. For example, if the manufacturing time required for a drug is fixed, it is possible to determine whether a reservation is possible based on the availability of resources. In such cases, the time-slot-specific reservation mode, which displays available time slots, can be used.

[0052] On the other hand, if the time required to manufacture a medication varies greatly depending on the patient's attributes and symptoms, it's impossible to determine availability based on resource availability. In such cases, a flexible scheduling model that displays unavailable time slots but allows for the selection of alternative time slots is sufficient.

[0053] Figure 7 This is the information processing flowchart for use case (1), "Display of bookable / unbookable schedules based on resource coordination decisions." Additionally, Figure 8 This is a summary diagram of the time-specified reservation mode and the free reservation mode for use case (1).

[0054] according to Figure 7 The information processing for use case (1) is explained below. First, the available time slot control unit 41 selects the reservation category of the available / unavailable time slot display object (step S101). Then, the available time slot control unit 41 obtains the coordination rule data 57 (step S102). In the reservation category of the coordination departure point, the available time slot control unit 41 determines the target associated with the reservation based on the target reservation category mapping data 55 (data storing various reservations and their associated targets) (step S103).

[0055] In relation to the reservation categories at the point of origin ( Figure 8 If the target associated with the reservation instance [Reservable] is making a reservation in the time-slot reservation mode (step S104; time-slot reservation mode), the reservation is made using the following process.

[0056] First, the available time slot control unit 41 obtains the earliest available time slot for each target (step S105), and calculates candidate schedules for the destination's booking category, using the booking category of the departure point as a starting point and referring to the coordination rule data 57 (step S106). For the booking category of the reference target, the available time slot control unit 41 determines the associated target based on the target booking category mapping data 55 (step S107), and confirms the availability of candidate schedules (whether there are any booking instances) for each unit of resource (step S108). The available time slot control unit 41 repeatedly confirms the availability of candidate schedules until all targets are confirmed to be available (step S109; "Yes").

[0057] If the availability of candidate dates cannot be confirmed (step S110; "No"), the process is repeated from obtaining the shortest available booking period for each target (step S105). Additionally, if the booking categories for all coordinated destinations have not yet been calculated (step S111; "No"), the booking category for the coordinated destination is changed to confirm the availability of candidate dates.

[0058] After calculating the schedules for all coordinated destination reservation categories (step S111; "Yes"), the available time slot control unit 41 displays the available time slots for the reservation category specified by the user.

[0059] Figure 8 The available booking times displayed indicate that the available booking times have been processed through the above information. The booking instance for Room 1 of Manufacturer Tenant X is a booking category coordinated from the departure point; the earliest available booking instance in the candidate schedules for that category is the booking instance for Hospital Tenant Y, connected by an arrow. Similarly, the booking instance for Room 2 of Manufacturer Tenant X also has its earliest available booking instance being the booking instance for Hospital Tenant Y, connected by an arrow.

[0060] In this way, the available time slots for the destination associated with the reservation category of the coordinated departure point are displayed when there are available slots for the destination associated with the reservation category in the candidate schedule of the coordinated destination calculated with reference to the coordinated rule data 57.

[0061] Therefore, when determining whether a destination is available for booking based on a booking category associated with a user-specified departure point, the user does not need to confirm the availability of the destination associated with the booking category, thus reducing the burden of schedule management.

[0062] Furthermore, since users do not need to confirm the availability of the target associated with the reservation category of the coordinated destination, it is still possible to manage the schedule considering the resources of the coordinated destination even when there are constraints that prevent the display of information such as the existence of reservation instances and available time slots for the coordinated destination to users at the origin of the coordination. When making a reservation for a target associated with the reservation category of the coordinated origin in the free reservation mode (step S104; free reservation mode), the reservation is made using the following process.

[0063] First, the available time slot control unit 41 obtains the confirmed time slots for each target (step S113), and calculates candidate schedules for the user-specified reservation category by referring to the coordination rule data 57, starting from the reservation category of the departure point (step S114). Next, for the user-specified reservation category, the associated target is determined according to the target reservation category mapping data 55 (step S115), and the availability of candidate schedules is confirmed for the unit resources of the determined target (step S116).

[0064] If the availability of all targets has not yet been confirmed (step S117; "No"), confirm the availability of candidate schedules equivalent to the number of target targets.

[0065] After confirming the availability of all targets (step S117; "Yes"), if no target is available (step S118; "No"), the process ends. If a target is available (step S118; "Yes"), the unbookable time slots for the user-specified reservation category are displayed. Figure 8 (Step S119) (The reservation example in the text is [unreservable]).

[0066] Figure 8 The "unbookable time slots" display indicates that these time slots are unbookable as per the information processing described above. The booking instances for Room 1 and Room 2 of Manufacturer Tenant X are bookings for the coordinated departure point, while the booking instance for Hospital Tenant Y, whose destination is unavailable and is displayed as an unbookable time slot, is connected by an arrow.

[0067] Figure 9 This is the information processing flowchart for use case (2), "Generating new reservations through inter-resource coordination." Additionally, Figure 10 This is a summary diagram of use case (2).

[0068] according to Figure 9 The information processing for use case (2) is explained. The appointment generation unit 42 first selects the case ID and appointment category, and generates a new resource appointment for the lessee (step S201), then obtains the coordination rule data 57 (step S202). Next, the appointment generation unit 42 generates the appointment category for the new appointment (…). Figure 10Starting with the appointment instance [already booked] of hospital tenant Y in the data, and referring to the coordination rule data 57, the candidate schedules for the appointment category of the coordination destination are calculated (step S203). For the appointment category of the coordination destination, the appointment generation unit 42 determines the associated target according to the target appointment category mapping data 55 (step S204), and confirms the availability of the candidate schedule for the unit resources of the determined target (step S205).

[0069] If the availability of all targets has not yet been confirmed (step S206; "No"), the reservation generation unit 42 confirms the availability of candidate schedules equivalent to the number of target schedules. After confirming the availability of all targets (step S206; "Yes"), if no target is available (step S207; "No"), the reservation generation unit 42 displays a dialog box indicating that other tenants are not available and interrupts the reservation generation process (step S210). If a target is available (step S207; "Yes"), the reservation generation unit 42 generates a new reservation by appending the case ID and schedule category (step S208). Figure 10 (The reservation instances of manufacturing lessee X and wholesale lessee Z in the data are [reserved]). At this time, in the case of reservation categories spanning multiple unit resources for a period, reservations for the quantity of that period are generated. The reservation generation unit 42 repeatedly performs the process starting from calculating the candidate schedules for reservation categories (step S203) until reservations for all reservation categories are generated (step S209; "Yes").

[0070] Figure 10 This indicates that appointments were generated through the aforementioned information processing. For an appointment instance in hospital lessee Y, partition C, resources for services scheduled before and after this date need to be booked; these services are determined based on appointment category / target mapping data. Based on the determined targets, the availability of candidate dates is confirmed, and new appointments are generated. These are appointment instances in partition B of manufacturing lessee X and partition D of wholesale lessee Z, connected by arrows.

[0071] Figure 11 This is the information processing flowchart for use case (3), "Cancellation of appointments through inter-resource coordination." Additionally, Figure 12 This is a summary diagram of use case (3).

[0072] according to Figure 8 Explain the information processing of use case (3). The reservation cancellation department 43 first registers the lessee's resource reservation cancellation (step S301). Figure 12The reservation instance of the lessee X in the manufacturing plant [reserved]). The reservation cancellation unit 43 obtains the case ID of the cancelled reservation instance and retrieves the business progress of the case from the business progress data (data that records the business progress status of the case) (step S302). Then, it obtains the model reservation category mapping data and calculates the reservation category of the cancellation object (the reservation category associated with the unexecuted business) (step S303). In addition, it determines the reservation instance associated with the case ID and reservation category of the cancellation object (step S304), and performs reservation cancellation processing on the determined reservation instance (step S305). Figure 12 The appointment instances of wholesale lessee Z and hospital lessee Y [already booked] are shown. At this time, if the appointment instances of all appointment categories of the object to be cancelled have not yet been cancelled (step S306; "No"), the process from determining the appointment instances associated with the case ID and appointment category of the object to cancellation (step S304) to cancellation processing (step S305) is repeated. When the appointment instances of all appointment categories of the object to be cancelled are cancelled (step S306; "Yes"), the process ends.

[0073] Figure 12 This indicates that the appointment instance was cancelled through the above information processing. For the appointment instance of Manufacturing Lessee X, Partition B, resources for business operations scheduled before or after this date were also coordinated and booked; these are the appointment instances of Hospital Lessee Y, Partition C, and Wholesale Lessee Z, Partition D, connected by arrows. In this state, when the appointment instance of Manufacturing Lessee X, Partition B, is cancelled, the associated appointment instances of Hospital Lessee Y, Partition C, and Wholesale Lessee Z, Partition D, are also cancelled.

[0074] As described above, the computer 10, which operates as a schedule management system in this embodiment, includes a storage unit 23 and a control unit 22. The storage unit 23 stores resource data (unit resource data 58) and coordination rules (coordination rule data 57) for a chain of multiple business related to supply. The control unit 22 performs schedule management of the aforementioned business with reference to the resource data and the coordination rules.

[0075] The aforementioned resource data refers to the data used by the facilities performing the aforementioned services to manage the idle status of the resources. The aforementioned coordination rules are rules that define the sequential relationship of the aforementioned services and represent the service intervals between the aforementioned facilities.

[0076] The control unit 22 determines the business that forms the chain based on the preceding and following relationships of the business, and determines the facilities that can perform the determined business. By referring to the availability of the resources of the determined facilities, it provides information on whether the above-mentioned supply can be reserved.

[0077] This structure and mechanism enable the appropriate implementation of schedule management for multiple cases involving multiple facilities.

[0078] In regenerative medicine, the various participating facilities often possess a high degree of independence, requiring control over the publicly disclosed scope of patient information and processing capabilities. Using the system of this invention, users do not need to confirm the availability of facilities to which they do not belong. Therefore, while suppressing information disclosure between facilities, it is possible for facilities to decide whether to accept appointments, including undisclosed information, even when an appointment request is made. In other words, it allows for coordinated scheduling management while respecting the autonomy of each facility.

[0079] In addition, the aforementioned control unit 22 also includes a time slot control unit 41.

[0080] The aforementioned reservation time slot control unit 41 can determine and provide information to the operator who makes the reservation for the aforementioned supply.

[0081] In addition, the aforementioned reservable time slot control unit 41 can identify and provide information to operators who make reservations for the aforementioned supply, as to which the reserved time slots have already been occupied by other reservations.

[0082] Specifically, the aforementioned reservation time slot control unit 41 determines and provides information on the reservation time slots for the supply of drugs of the first category, and determines and provides information on the reservation time slots that have been occupied by other reservations for the supply of drugs of the second category.

[0083] Therefore, appropriate information can be provided according to the category of the drug.

[0084] In addition, the aforementioned storage unit 23 also stores case data 60 for managing the aforementioned supply on a case-by-case basis, and the aforementioned control unit 22 also includes a reservation generation unit 42.

[0085] For the aforementioned case, the appointment generation unit 42 determines the business that forms the chain based on the preceding and following relationships of the aforementioned business, identifies the facility capable of performing the identified business, makes an appointment for the resources of the identified facility, and associates the case identification information.

[0086] In addition, the aforementioned control unit 22 also includes a reservation cancellation unit 43.

[0087] For cases designated for cancellation, the aforementioned cancellation department 43 determines the business that forms the chain based on the preceding and following relationships of the aforementioned business, identifies the facilities capable of performing the identified business, and sequentially cancels the reservations for the resources of the identified facilities.

[0088] Thus, the system of the present invention can appropriately determine and cancel reservations based on coordination rules.

[0089] Furthermore, the structure and operation shown in the embodiment are only examples, and the present invention can be implemented by appropriately modifying the structure and operation.

[0090] For example, computer 10 does not need to be a device with a physical chassis; it can also combine virtual resources to achieve the same actions as computer 10.

[0091] The example described specifically uses the scheduling adjustment function in a system for managing the supply chain of autologous cells, but it can also be applied to systems that manage the supply chain when using allogeneic cells. Furthermore, it can be applied to systems that manage the supply chain of a series of steps involving multiple facilities, even for products other than regenerative medicine.
