BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a schedule adjustment system to which the present invention is applied will be described. This system adjusts the schedule when the user sets a schedule for a meeting or the like, and the meetings that cannot be removed are duplicated. For each meeting, if the minimum attendance time is satisfied, it is possible to be late or leave early, and based on the priority of each meeting, the impact of late or early leaving, the late time or early leaving time, a predetermined evaluation algorithm according to a predetermined evaluation algorithm. By performing the calculation, a quantitative evaluation value can be obtained, and a schedule adjustment plan can be presented to the user in order from the optimal one based on the evaluation value.
[0008]
FIG. 1 shows a configuration example of an embodiment of a schedule adjustment system to which the present invention is applied. As shown in FIG. 1, the present embodiment includes a server 1, a client 2, a firewall (F / W) 4, the Internet 5, and a mobile phone 3. The server 1 and the mobile phone 3 are connected via the Internet 5 and can transmit and receive data. The server 1 and the client 2 are connected via a LAN (local area network) 6 and transmit and receive data. Can be done.
[0009]
The server 1 includes a workstation, a personal computer, and the like, and includes a storage device (not shown) for storing schedule data and the like of each user, a CPU (central processing unit), a memory, and the like. A processing unit for calculating an evaluation value, etc., a communication control unit (not shown) connected to the Internet 5 via the F / W 4 to transmit and receive data to and from the mobile phone 3 and the like, and a client 2 via the LAN 6 And a LAN control unit (not shown) for exchanging data.
[0010]
The client 2 includes a personal computer or the like, and includes a LAN control unit (not shown) for exchanging data with the server 1 via the LAN 6.
[0011]
The mobile phone 3 controls each unit and executes various programs, a not-shown control unit, stores various data, a not-shown storage unit, a display unit 3a that displays various data, and inputs data and commands. 3b, a communication control unit (not shown) for controlling communication, an antenna 3c, and the like. The user who is the owner of the mobile phone 3 operates the button 3b of the mobile phone 3 to input schedule data. Has a function of transmitting to the server 1 via the Internet 5 via a packet communication network of a mobile phone company (not shown). The schedule data is data including a start time and an end time of an event such as a meeting, and a priority of the event set by a user as described later.
[0012]
Next, the operation of the present embodiment will be described. First, the user operates the button 3b of the mobile phone 3 to start the schedule management program by inputting a user ID and a password. The schedule management program executes a process of displaying an input screen for a user to input schedule data on the display unit 3a and transmitting the input schedule data to the server 1 via the Internet 5. I have.
[0013]
Next, the user operates the button 3b of the mobile phone 3 to input his / her own schedule data. The schedule data includes the date (execution date) of an event such as a meeting or a meeting, the start time and the end time, and the priority set by the user for this event. Thus, the user first enters the date of the event, then enters the start time, then enters the end time, and finally enters the priority of the event. The priority set for each event is represented by, for example, a numerical value from 1 to 10, and may be set by the user subjectively, or may be set according to a predetermined criterion. .
[0014]
The schedule data input by the user operating the button 3b of the mobile phone 3 is temporarily stored in a storage unit (not shown) of the mobile phone 3. Thereafter, when the user operates the button 3b to instruct to transmit the schedule data to the server 1, the control unit of the mobile phone 3 reads the schedule data stored in the storage unit and supplies the schedule data to the communication control unit. The communication control unit transmits the schedule data supplied from the control unit to the server 1 via the Internet 5.
[0015]
When receiving the schedule data and the user ID transmitted from the mobile phone 3 via the Internet 5 and the F / W 4, the server 1 stores the received schedule data and the user ID in a storage device (not shown) in association with each other.
[0016]
When the user operates the button 3b of the mobile phone 3 to input a desired date and instructs the schedule adjustment on this day, the mobile phone 3 sends the schedule on the date to the server 1 via the Internet 5. Transmit data instructing to make adjustments. This data includes data indicating a desired date and data instructing to perform schedule adjustment. Alternatively, every time a user inputs schedule data, the server 1 can automatically adjust the schedule.
[0017]
When the server 1 receives the data transmitted from the mobile phone 3 via the Internet 5 and the F / W 4, the server 1 shows schedule data on the instructed date corresponding to the user ID input from the mobile phone 3. Read from the storage device and adjust the schedule. The procedure of the schedule adjustment by the server 1 will be described in detail with reference to the flowchart of FIG.
[0018]
FIG. 2 is a flowchart illustrating a procedure in which the server 1 performs schedule adjustment based on schedule data. First, in step S1, a processing unit (not shown) of the server 1 reads out schedule data on a date designated by a user who owns the mobile phone 3 from a storage device (not shown) and expands the schedule data in a memory (not shown). That is, the schedule data of the user is searched from the storage device using the user ID and date input from the mobile phone 3 owned by the user as search keys, and the obtained schedule data is expanded in the memory.
[0019]
Next, in step S2, based on the schedule data expanded in the memory in step S1, the time period from the start time to the end time of each event is set to the time period from the start time to the end time of another event. It is checked whether or not some or all of them overlap.
[0020]
When attention is paid to a certain event, the overlapping patterns include a pattern that overlaps by a predetermined time from the start time (left), a pattern that overlaps by a predetermined time before the end time to an end time (right), The pattern that overlaps for a predetermined time from the time and overlaps from the time before the end time by a predetermined time to the end time (both), the time zone from the start time to the end time is from the start time of other events to the end A pattern (buried) included in the time zone up to the time and the time zone from the start time to the end time are the same (same) as the time zone from the start time to the end time of another event.
[0021]
Next, in step S3, as a result of the check in step S2, it is determined whether the time zone of the predetermined event is partially or entirely overlapped with the time zone of another predetermined event. As a result, when it is determined that the time zone of the predetermined event does not partially or entirely overlap the time zone of the other predetermined event, the process ends. On the other hand, when it is determined that the time zone of the predetermined event is partially or entirely overlapped with the time zone of the other predetermined event, the process proceeds to step S4.
[0022]
In step S4, an evaluation value is calculated for each possible overlapping pattern (schedule adjustment plan). The evaluation value of each overlapping pattern is calculated according to the following equation (1). That is, all the overlapping patterns of the schedule on the predetermined date are obtained, and for each overlapping pattern, an evaluation value is calculated according to the equation (1) for an event in which the schedule is changed in each overlapping pattern. If there are a plurality of events in which the schedule is changed (events in which at least one of the start time and the end time is changed), the sum of the evaluation values of those events is used as the evaluation value of the overlapping pattern. (Equation (2)).
[0023]
Evaluation value of each event = {(Evaluation reference value by priority of events such as meetings) × (Evaluation reference value by state) × (State time)} (Equation 1)
[0024]
Evaluation value of overlapping pattern = {(Evaluation reference value by priority of event 1 such as meeting) × (Evaluation reference value by state) × (state time)} +... + ｛(Priority of event N such as meeting (Evaluation reference value for each condition) × (Evaluation reference value for each condition) × (State time)｝ (Formula 2)
Here, N is the number of events whose schedule is changed.
[0025]
Here, the evaluation reference value for each priority of an event such as a meeting is an evaluation reference value corresponding to the priority set by the user, and can be obtained from FIG. The evaluation reference value for each state (hereinafter referred to as the reference value for late status or the reference value for early retirement, as appropriate) is the evaluation reference value when the event is late for an event such as a meeting, or when the event such as a meeting is retired. This is an evaluation reference value. The state time is the time when the event such as a meeting is delayed, and the time from the time when the event such as a meeting is retired to the end time of the event when the event such as a conference is retired.
[0026]
For example, the start time of meeting A is 10:00 am, the end time is 14:10 pm, the priority set for meeting A is 5, the evaluation reference value by priority is 6, and the start time of meeting B is pm 14:00, the end time is 16:00 pm, the priority set for the B meeting is 3, the evaluation reference value by priority is 8, the start time of the C meeting is 15:40 pm, and the end time is the afternoon. At 18:00, it is assumed that the priority set for the C conference is 7 and the evaluation reference value for each priority is 4.
[0027]
In this case, four overlapping patterns can be considered as shown in FIG. FIG. 5A shows an overlapping pattern in which the user is late for the conference B by 10 minutes and is late for the conference C by 20 minutes. FIG. 5B shows an overlapping pattern in which the B meeting is delayed by 10 minutes, and the B meeting leaves early 20 minutes before the end time. FIG. 5C shows an overlapping pattern in which the conference A retreats early 10 minutes before the end time and is late for the conference C by 20 minutes. FIG. 5D shows an overlapping pattern in which the conference A retreats early 10 minutes before the end time and the conference B retreats 20 minutes before the end time.
[0028]
As described above, the priority is set for each conference. Then, for each priority, an evaluation reference value for each priority used in the evaluation value calculation is set. FIG. 3 shows an example of the evaluation reference value for each priority. In the case of this example, the priority-based evaluation reference value corresponding to the priority 1 is set to 10. The priority-based evaluation reference value corresponding to the priority 2 is set to 9. The priority-based evaluation reference value corresponding to the priority 3 is set to 8. The priority-based evaluation reference value corresponding to the priority 4 is set to 7. The priority-based evaluation reference value corresponding to the priority 5 is set to 6. The priority-based evaluation reference value corresponding to the priority 6 is set to 5. The priority-based evaluation reference value corresponding to the priority 7 is set to 4. The priority-based evaluation reference value corresponding to the priority 8 is set to 3. The priority-based evaluation reference value corresponding to the priority 9 is 2. The priority-based evaluation reference value corresponding to the priority 10 is set to 1.
[0029]
Since the priority set for the conference A is 5, the priority-based evaluation reference value of the conference A is set to 6 from FIG. Since the priority set for the conference B is 3, the priority-based evaluation reference value of the conference B is set to 8 from FIG. Since the priority set for the conference C is 7, the priority-based evaluation reference value of the conference C is set to 4 from FIG.
[0030]
FIG. 4 shows an example of a reference value corresponding to the late state and a reference value corresponding to the early retreat state used for calculating the evaluation value. In this example, the reference value in the case of being late is 7 and the reference value in the case of leaving early is 5. In other words, the influence due to being late is greater than the influence due to leaving early.
[0031]
The evaluation value of the overlapping pattern as shown in FIG. 5A is 1120 (= 8 (evaluation reference value by B conference priority) × 7 (lateness state reference value) × 10 minutes (state time) +4 (C conference priority) (Evaluation reference value for each degree) × 7 (reference value for late state) × 20 minutes (state time)).
[0032]
The evaluation value of the overlapping pattern as shown in FIG. 5B is 1360 (= 8 (Evaluation reference value by B conference priority) × 7 (Late state reference value) × 10 minutes (state time) +8 (B conference priority) (Evaluation reference value per degree) × 5 (Early retreat state reference value) × 20 minutes (state time)).
[0033]
The evaluation value of the overlapping pattern as shown in FIG. 5C is 860 (= 6 (Evaluation reference value by A conference priority) × 5 (Early leaving state reference value) × 10 minutes (state time) +4 (C conference priority) (Evaluation reference value for each degree) × 7 (reference value for late state) × 20 minutes (state time)).
[0034]
The evaluation value of the overlapping pattern as shown in FIG. 5 (D) is 1100 (= 6 (Evaluation reference value by A conference priority) × 5 (Early leaving state reference value) × 10 minutes (state time) +8 (B conference priority) (Evaluation reference value per degree) × 5 (Early retreat state reference value) × 20 minutes (state time)).
[0035]
Therefore, in the case of the overlapping pattern in FIG. 5C, the evaluation value is 860, which is the smallest. It is said that the smaller the overlapping pattern of the evaluation value, the better. As shown in FIG. 3, in this example, the priority-based evaluation criterion value is set to be larger as the priority is higher, and as shown in FIG. , A value larger than early retreat is set. Therefore, the evaluation value is smaller in the overlapping pattern in which the schedule is changed from the event having the lower priority. For the same event, the sum of the evaluation values is smaller in the overlapping pattern including the early retreat state than in the late state.
[0036]
When the calculation of the evaluation value for each overlapping pattern is completed, the process proceeds to step S5 in the flowchart of FIG. 2, and the evaluation values for each overlapping pattern calculated in step S4 are sorted in ascending order of the evaluation value.
[0037]
Next, in step S 6, the server 1 creates adjustment plan data for displaying the overlapping patterns on the display unit 3 a of the mobile phone 3 as adjustment plans in descending order of evaluation value (smallest), and transmits the same via the Internet 5. To the mobile phone 3. The mobile phone 3 which has received the adjustment plan data transmitted from the server 1 displays the adjustment plan data on the display unit 3a in order from the overlapping pattern having the highest evaluation value (smallest) based on the received adjustment plan data.
[0038]
In the example of the overlapping pattern shown in FIG. 5, the overlapping pattern of FIG. 5C, the overlapping pattern of FIG. 5D, the overlapping pattern of FIG. 5A, and the overlapping pattern of FIG. Will be done.
[0039]
Next, when the user operates the button 3b of the mobile phone 3 and instructs a process to be performed next, in step S7, the control unit (not shown) of the mobile phone 3 determines the process instructed by the user. You.
[0040]
As a result, when it is determined that an instruction to display the next adjustment plan has been issued, the process proceeds to step S8, and the control unit of the mobile phone 3 causes the display unit 3a to display an overlapping pattern having the next smallest evaluation value. Thereafter, the process returns to step S7, and the processes after step S7 are repeatedly executed. On the other hand, if it is determined that an instruction to change the priority has been given, the process proceeds to step S9, and the user continues to operate the button 3b to select a meeting whose priority is to be changed, and to set a new priority for the meeting. Enter The mobile phone 3 sets a new priority input by the user for the conference selected by the user, and transmits the new priority to the server 1 via the Internet 5. Thereafter, the process returns to step S4, and the processes after step S4 are repeatedly executed. When it is determined that the instruction to accept the adjustment plan has been given, the process proceeds to step S10, and the control unit of the mobile phone 3 indicates that the overlapping pattern as the adjustment plan displayed on the display unit 3a has been determined. The data is transmitted to the server 1 via the Internet 5. Upon receiving the data transmitted from the mobile phone 3 via the Internet 5, the server 1 updates the schedule data stored in the storage device (not shown) according to the determined duplication pattern. That is, in the case of this example, the end time of the conference A is advanced by 10 minutes and the start time of the conference C is delayed by 20 minutes in accordance with the overlapping pattern of FIG.
[0041]
Eventually, the start time of the conference A is 10:00 and the end time is 14:00. The start time and end time of the B meeting are not changed, and the start time is 14:00 and the end time is 16:00. The start time of the C meeting is 16:00, and the end time is 18:00.
[0042]
FIG. 6 shows an example in which the schedule data of the conference A and the conference C are already input and stored in the storage device of the server 1, and the schedule data of the conference B is input. 9 shows an example of an adjustment plan display selection screen in which values are calculated and displayed on the display unit 3a of the mobile phone 3. In the adjustment proposal display selection screen of FIG. 6, the event name (in this case, meeting B), the scheduled execution date of the event (in this case, July 25, 2002), and the first adjustment proposal can be selected. The selection items "2 proposals", "acceptance", "priority ↑", and "priority ↓" indicating the processing to be performed next are displayed.
[0043]
In this example, the first arbitration plan (plan 1) corresponds to the overlapping pattern in FIG. 5C, and the character string "-am--14-16" represents the time. "O" on the left side of the next line indicates the A conference. The symbol “■” in the center represents the B conference. "O" on the right side indicates the C conference. “1” displayed on the right side of “○” representing the meeting A indicates that the meeting A is to leave early 10 minutes before the end time. 2 on the left side of “○” representing the C meeting indicates that the user will be attending the C meeting 20 minutes late.
[0044]
The selection item “2 proposals” is for instructing display of the next adjustment proposal. The selection item “accept” is for instructing acceptance of the displayed adjustment proposal. The selection item “priority #” is for instructing to raise the priority of the B conference to which the schedule data has been input. The selection item "priority ↓" is for instructing to lower the priority of the B conference to which the schedule data has been input.
[0045]
When the user operates the button 3b and selects "2 proposals", the display unit 3a of the mobile phone 3 displays the next adjustment proposal (the overlapping pattern with the next smallest evaluation value). When the user operates the button 3b and selects "accept", the adjustment proposal displayed on the display unit 3a is determined and stored in the storage unit (not shown). Further, schedule data indicating the decided adjustment plan is transmitted to the server 1 via the Internet 5. The server 1 receiving the schedule data stores the schedule data in the storage device.
[0046]
FIG. 7 shows a configuration example of schedule data stored in a storage device (not shown) of the server 1. As shown in the drawing, schedule data includes a schedule ID for identifying a schedule, a schedule name (event name), a schedule priority (event priority), an implementation date, an implementation location, a participating user ID, and a start. It consists of a time, an end time, a time allowed to be late (unit is minutes), and a time allowed to leave early (units are minutes). The time allowed to be late is a time that may be delayed if a predetermined minimum attendance time is satisfied. Time from the time to the end time of the event). The time allowed to be late and the time allowed to leave early may be set in advance, or may be input and set by the user.
[0047]
In the embodiment shown in FIG. 1, the server 1 calculates the evaluation value for each overlapping pattern based on the schedule data, but the control unit of the mobile phone 3 operates the button 3b by the user. Then, the input schedule data is stored in a storage unit (not shown), based on the schedule data stored in the storage unit, an overlapping pattern is obtained, and an evaluation value of each overlapping pattern is calculated. , And may be sequentially displayed on the display unit 3a as an adjustment proposal. In this case, the screen displayed on the display unit 3a may be the same screen as the adjustment proposal display selection screen shown in FIG.
[0048]
When the user operates the button 3b of the mobile phone 3 and selects the selection item "2 proposals" on the adjustment proposal display selection screen displayed on the display unit 3a, the control unit (not shown) of the mobile telephone 3 controls Next, the adjustment plan with the smallest evaluation value is displayed on the display unit 3a. On the other hand, when the button 3b of the mobile phone 3 is operated by the user and the selection item “accept” on the adjustment proposal display selection screen displayed on the display unit 3a is selected, the display unit is controlled by the control unit of the mobile phone 3. The adjustment plan displayed in 3a is determined, and the schedule data stored in the storage unit is updated based on the adjustment plan.
[0049]
When the user operates the button 3b of the mobile phone 3 and selects the selection item “priority ↑” on the adjustment proposal display selection screen displayed on the display unit 3a, the display is controlled by the control unit of the mobile phone 3. The priority of the B meeting of the adjustment proposal displayed in the section 3a is raised, and the schedule data is updated. After that, the evaluation value of each overlapping pattern is recalculated, and the overlapping patterns with the smaller evaluation values are displayed on the display unit 3a in order. When the user operates the button 3b of the mobile phone 3 and selects the selection item “priority ↓” on the adjustment proposal display selection screen displayed on the display unit 3a, the display is controlled by the control unit of the mobile phone 3. The priority of the B meeting of the adjustment proposal displayed in the section 3a is lowered, and the schedule data is updated. After that, the evaluation value of each overlapping pattern is recalculated, and the overlapping patterns with the smaller evaluation values are displayed on the display unit 3a in order.
[0050]
As described above, when setting the schedule of a personal meeting, etc., when the time zone of the meeting that cannot be removed is partially or entirely overlapped with the time zone of other meetings, the priority of each meeting, Alternatively, by calculating a quantitative evaluation value in consideration of the influence of early retirement, the schedule is adjusted so that the user can participate in all conferences with equal strength, that is, minimize the adverse effect. be able to.
