JP 2003-187046 A JP 2003-99573 A Japanese Patent Laid-Open No. 08-161397

  In the conventional technology, data relating to schedules of different granularities such as company schedules, department schedules, and individual schedules are recorded and managed in independent devices. That is, company schedules, department schedules, and individual schedules have not been formalized on the system consistently. In addition, data on individual schedules / work management, etc. was recorded in a distributed manner on each individual terminal.

  Therefore, these schedules with different granularities have not been managed with hierarchical dependency. Specifically, for example, dependency relationships between operations are not defined in consideration of hierarchy, such as company schedules and department schedules, department schedules and individual schedules, and department schedules. In other words, for example, a certain department and other departments related to work performed in the department are not managed in association with schedule management.

  The conventional techniques as described above have the following problems. That is, it is difficult to grasp the progress of other departments related to a certain department. Therefore, it takes time to determine which other departments are affected by a problem that occurs in a certain department, or the judgment cannot be made, resulting in a delay or stagnation in the work.

  Accordingly, an object of the present invention is to solve these problems and to provide an apparatus, a method, and the like that can manage each schedule by providing hierarchical dependency relationships.

In order to solve the above problems, the present invention is configured as follows. A first aspect of the present invention is a schedule management apparatus, which includes a storage unit, a determination unit, and a display unit. The storage means stores development schedule data that is hierarchized according to use and further classified by work within a predetermined hierarchy. In addition, the storage unit stores the relevance between the tasks in the hierarchy. Furthermore, the storage means further stores the mutual relationship with the upper and / or lower hierarchy for each hierarchy. Hierarchization according to the use may be, for example, according to the use according to the hierarchical level of the organization. Specifically, it may be hierarchized like a company level, a department level, or an individual level. Moreover, the classification according to work may be, for example, a classification according to work for developing one product. In addition, more specifically, the classification by work may be a classification according to a development field for developing a vehicle, for example. The relevance between the work indicates, for example, the context of the work or the dependency such as the same work.

  The judging means judges the contents to be notified to the user by judging the consistency of the development schedule. At this time, the determination means determines the consistency of the schedule based on the relevance of each schedule stored in the storage means. The display means displays a screen corresponding to the determination result by the determination means.

  According to the 1st aspect of this invention comprised in this way, each schedule is hierarchized according to a use, and it manages with a relationship (dependency relationship). In addition, according to the first aspect of the present invention, the mutual relationship is stored even for the schedules in different hierarchies, so that the user can easily determine other schedules related to a certain schedule. It becomes.

  A second aspect of the present invention is a storage unit that stores data of development schedules that are hierarchized according to use and further classified by work within a predetermined hierarchy. The storage means in the second aspect of the present invention further stores the reciprocal relationship between the tasks in the hierarchy and the reciprocal relationship between the upper and / or lower hierarchies. Also according to the second aspect configured as described above, each schedule is hierarchized according to the use, and managed with relevance (dependency).

  In addition, the storage unit in the second aspect of the present invention may be configured to further store a security level related to development schedule data in each hierarchy and each classification. With this configuration, it is possible to protect the confidentiality of the data for each development schedule.

  A third aspect of the present invention is a schedule management device, which includes a storage unit, a user identification unit, a determination unit, a display unit, and a selection unit. The storage means stores the schedule of each set in a plurality of sets configured hierarchically. The set here may be, for example, each set (department or the like) according to the hierarchical structure of the organization. Specifically, it may be a group as a whole company, a group as each department, or a group as each individual. The user specifying means specifies a user. In addition, the storage unit further stores a mutual relationship regarding the schedule of each set. The mutual relationship indicates, for example, a context as a work related to a schedule or a dependency such as the same work.

  Any existing method for specifying a user may be applied to the user specifying means. For example, the user specifying unit may specify the user based on an ID and a password input by the user, or may specify the user based on data stored in a storage unit carried by the user.

  The display means displays the contents of the schedule determined by the determination means. The selection means is used to select a schedule that the user desires to be displayed on the display means. The selection of the schedule may be realized by any method. For example, when there is a format in which a schedule to be displayed in advance is set, the selection means is not configured to be able to directly select the schedule, but is configured to be able to select the format. Also good. The selection means may be configured so that the user can directly select a schedule that the user wants to display.

The determining means determines the content of the schedule to be presented to the user specified by the user specifying means. Specifically, the determination means is a schedule of a set to which the specified user belongs, or a schedule of another set having relevance to a schedule of the set to which the specified user belongs, and the schedule selected by the selection means. The schedule corresponding to is determined as the schedule to be displayed.

  Also with the schedule management device according to the third aspect configured as described above, each schedule is hierarchized and managed with a relationship (dependency relationship). In addition, since the mutual relationship is stored for the schedules in the different layers, the user can easily determine other schedules related to a certain schedule. In addition, according to the schedule management device according to the third aspect, since the display content corresponding to the user is determined by the determining means, it is possible to provide a display that is more convenient for the user. Specifically, not only the schedule of the set to which the user belongs, but also the schedule of another set that is related to the schedule of the set to which the user belongs is determined and displayed by the determination means. Therefore, the user can easily determine the schedule of another set related to the schedule of the set to which the user belongs without considering the relevance by himself / herself.

  The storage means in the third aspect of the present invention may be configured to further store a confidential level for the schedule of each set. In this case, the determination means in the third aspect may be configured to determine to display only the schedule of the confidential level according to the specified user. With this configuration, access control can be realized for the contents of each schedule, and the confidential level can be maintained.

  The third aspect of the present invention may be configured to further include changing means for the user to change the contents of the schedule stored in the storage means. In this case, when the content of the schedule stored in the storage means is changed by the changing means, the judging means in the third aspect of the present invention detects the schedule of another set having relevance to the changed schedule. Then, it may be configured to determine whether to give a warning to the users belonging to the set of detected schedules. By being configured in this manner, a warning is issued to a user who may be affected by a schedule changed by another user. Therefore, it is possible to maintain consistency between the schedules. In addition, the contents of the schedule changed by another user can be appropriately grasped by the user who is affected by the change.

  A fourth aspect of the present invention is a schedule management system, which includes a schedule management server and a schedule management terminal. The schedule management server includes storage means, user identification means, determination means, reception means, and transmission means. The storage means stores the schedule of each set in a plurality of sets configured hierarchically. In addition, the storage unit further stores a mutual relationship regarding the schedule of each set. The user specifying means specifies a user. The determining means determines the content of the schedule to be presented to the user specified by the user specifying means. The determination means is a schedule of a set to which the specified user belongs, or a schedule of another set having relevance to a schedule of the set to which the specified user belongs, and corresponds to the schedule selected by the selection means. The schedule is determined as the schedule to be displayed. The receiving means in the schedule management server receives data from other devices. For example, the receiving means in the schedule management server may receive data transmitted from the schedule management terminal. The transmission means in the schedule management server transmits the contents of the schedule determined by the determination means to other devices. The other device may be a schedule management terminal included in the same system, for example.

  The schedule management terminal includes a reception unit, a display unit, a selection unit, and a transmission unit. The receiving means in the schedule management terminal receives the contents of the schedule determined by the determining means in the schedule management server. The display means displays the contents of the schedule received by the receiving means. The selection means is used to select a schedule that the user desires to be displayed on the display means. The transmission means in the schedule management terminal transmits data indicating the schedule selected by the selection means to the schedule management server. The schedule management system may include a plurality of schedule management terminals.

  According to the 4th aspect of this invention comprised in this way, a schedule management terminal can be installed in the place away from the schedule management server. In addition, a plurality of schedule management terminals can be installed for one schedule management server. For this reason, the convenience for the user is improved. Further, the storage means and the judgment means in the fourth aspect of the present invention may be configured as the same means in the third aspect of the present invention. The schedule management terminal according to the fourth aspect of the present invention may be configured to further include the same means as the changing means according to the third aspect.

  The configurations described above can be combined as much as possible. In addition, the first aspect, the third aspect, and the fourth aspect may be realized by executing a program by the information processing apparatus. That is, the present invention records a program for causing an information processing apparatus to execute the processing executed by each means in the first aspect, the third aspect, and the fourth aspect, or the program. It can be specified as a recording medium. In addition, the present invention may be specified by a method in which the information processing apparatus executes the process executed by each unit in the first aspect, the third aspect, and the fourth aspect.

  According to the present invention, each schedule can be managed with hierarchical dependency.

[Device configuration]
Hereinafter, the structural example of the schedule management apparatus 1 by this invention is demonstrated. The schedule management device 1 is a device for centrally managing the vehicle development schedule. However, such a schedule management device 1 is only a specific example, and the schedule management device 1 may be configured to perform processing for other schedule management.

  The schedule management device 1 includes a CPU (Central Processing Unit), a main storage device (RAM), an auxiliary storage device, and the like connected via a bus in terms of hardware. The auxiliary storage device is configured using a nonvolatile storage device. The non-volatile memory device referred to here is a so-called ROM (Read-Only Memory: EPROM (Erasable Programmable Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory, etc.). ), Hard disk, etc.

  FIG. 1 is a diagram showing an example of functional blocks of a schedule management apparatus 1 according to the present invention. The schedule management device 1 loads various programs (OS, applications, etc.) stored in the auxiliary storage device into the main storage device and is executed by the CPU, whereby the schedule storage unit 2, the input unit 3, the determination unit 4, And functions as a device including the display unit 5 and the like. The determination unit 4 is realized by the program being executed by the CPU. The determination unit 4 may be configured as a dedicated chip. Next, each functional unit included in the schedule management device 1 will be described.

[Schedule storage part]
The schedule storage unit 2 is configured using a so-called nonvolatile storage device. FIG. 2 is a diagram illustrating a configuration example of data stored in the schedule storage unit 2. The schedule storage unit 2 stores data relating to schedules having different granularities for each of one or more management objects in association with a hierarchy corresponding to the granularity. The hierarchy according to the granularity is, for example, a hierarchy according to the application. The management target indicates one project, and may be, for example, a vehicle development project. Each of the plurality of rectangles 6 in FIG. 2 represents one project. And each such management object contains the schedule of several different granularity. For example, the schedule storage unit 2 stores the company schedule as the highest hierarchy, the schedule of each department (department schedule) as the middle hierarchy, and the personal schedule as the lowest hierarchy. In this case, the company schedule, department schedule, and individual schedule correspond to data relating to schedules having different granularities. That is, the hierarchies are made according to uses such as company-wide use, department use, and personal use.

  The department schedule may be further classified by work. For example, the department schedule may be further classified by development field. That is, the middle hierarchy may be defined as a plurality of departments according to the development field, such as an exterior department, a content department, and a lamp department. In addition, the department schedule may be configured to include schedules related to a plurality of operations occurring in one department. That is, a department schedule corresponding to one department may be configured to include a plurality of schedules.

  The personal schedule may include a user's personal schedule and a schedule that is common within a group to which the user belongs (a group here indicates a set of units smaller than a department). Further, any of the user's individual schedule and the schedule common in the group may be configured to include schedules related to a plurality of operations. For example, when a user performs two tasks in parallel, the user's personal schedule may be configured to include a schedule for each of these two tasks.

  Further, the schedule storage unit 2 stores a dependency schedule between operations for a department schedule for a company schedule, a personal schedule for a department schedule, department schedules, and individual schedules. In FIG. 2, each schedule connected by a straight line or curve having black circles at both ends indicates that there is a dependency. The dependency relationship between the operations in the department schedule for the company schedule and the individual schedule for the department schedule is, for example, an upper / lower relationship. Specifically, it is a department schedule included in a company-wide schedule, a personal schedule included in a department schedule, or the like. The dependency relationship between the work for the department schedules or between the individual schedules means a relationship having a possibility of affecting the other work when, for example, delay or stagnation occurs in one work. Specific examples of dependency relationships between tasks include the context between tasks (required to perform the other task after one task) or the same task relationship (required to perform tasks simultaneously). and so on.

  Further, the schedule storage unit 2 stores accessible levels (personal positions, uses, etc.) for each layer and each classification. For example, for the company schedule, the access level may be set so that only a person in the position of the department head or higher in each department can access. Further, for example, for department schedules in other departments other than the department to which a certain user belongs, the access level may be set so that only people in positions other than the department head in each department can access. In addition, for example, even if a general employee has access level settings so that he / she can access only his / her own personal schedule (schedule of his / her own group and schedule of the group to which he / she belongs) and the schedule of the department to which he / she belongs. good.

[Input section]
The input unit 3 is realized using, for example, an input device such as a pointing device (tablet, mouse, etc.), a keyboard, or a button. The user can input commands and data to the schedule management device 1 by operating the input unit 3. For example, by operating the input unit 3, the user can input a project, a hierarchy, or a department for which a schedule is to be displayed, and can select a schedule to be displayed. In this case, the input unit 3 functions as a selection unit. Further, the user can input data (ID, password, etc.) for specifying an individual by operating the input unit 3. 3 and 4 are diagrams illustrating examples of input screens for performing input by the input unit 3. The display examples of FIGS. 3 and 4 are displayed by the display unit 5 described later.

FIG. 3 is a display example for selecting a vehicle type as a project and a part as a department. In the case of the display example of FIG. 3, the user can select the check box using the input unit 3, thereby selecting the vehicle type and the part related to the schedule to be displayed. In this case, the user can select whether or not to display the schedule for another part (that is, another department) by checking the “display other part” check box. Further, the user can select whether or not to display the schedule of the part to which the user belongs by checking the “display part schedule” check box. In this case, the user can input a command for executing the process assigned to the button by selecting the “next screen” button or the “cancel” button with the pointing device. For example, when the “next screen” button is selected on the screen of FIG. 3, the screen shown in FIG. 4 may be displayed as the next screen. Further, when the “cancel” button is selected, the operation as the schedule display device 1 may be terminated.

  FIG. 4 is a display example of the next screen when the “other part display” check box in FIG. 3 is checked. In the case of the display example in FIG. 4, the user can select other parts to be displayed using check boxes in the same manner as described above. In addition, the user can select the “OK” button, “Return” button, and “Cancel” button in the same manner as described above. For example, a schedule display screen (a screen shown in FIG. 7 described later) may be displayed by selecting a “decision” button on the screen of FIG. Further, the screen of FIG. 3 may be displayed by selecting the “Return” button on the screen of FIG. 4. Further, the operation as the schedule management device 1 may be ended by selecting a “cancel” button on the screen of FIG.

  In addition, when a password is required, the user can input a password necessary for accessing predetermined data by operating the input unit 3. Further, when a change occurs in the user's personal schedule, the schedule of the group to which the user belongs, the schedule of the department to which the user belongs, the company schedule, etc., the change of the schedule is stored in the schedule storage unit 2. In order to be reflected in the data, the change contents of the schedule can be input by operating the input unit 3. In this case, the input unit 3 functions as a changing unit. In this case, it is desirable that only the user according to the access level to each data can input the schedule change content.

(Judgment part)
The determination unit 4 determines the content to be displayed on the display unit 5 in accordance with the content input via the input unit 3, and instructs the display unit 5 to perform display based on the content. When an instruction regarding a display item is input via the input unit 3, the determination unit 4 determines specific contents to be actually displayed based on the instructed display item. For example, when the determination unit 4 instructs the user to display the schedule display screen of the project by selecting the project, the company schedule of the project, the department schedule of the department to which the user belongs, Depending on the access level of this user among the department schedules of other departments that are dependent on this department schedule, the personal schedule of this user, and the personal schedules of other users that are dependent on this user's personal schedule It may be determined to display the contents.

  Moreover, the determination part 4 may be comprised so that display content may be determined according to a user's attribute. For example, when the user is the department head, the determination unit 4 does not display the personal schedule, but the company schedule, the department schedule of the department to which the user belongs, and other departments that are dependent on the department schedule. It may be configured to display only the department schedule. FIG. 5 is a diagram illustrating an example of a display concept when such a determination is performed by the determination unit 4. At this time, the determination unit 4 also determines whether or not this user can access the company schedule and schedules of other departments, and instructs the display unit 5 to display only when possible. .

Further, for example, when the user inputs via the input unit 3 to display the personal schedule display screen, the determination unit 4, the department schedule of the department to which the user belongs, the personal schedule of the user, It may be determined to display the personal schedule of another user who has a dependency with the personal schedule. FIG. 6 is a diagram illustrating an example of a display concept when such a determination is performed by the determination unit 4. At this time, the determination unit 4 also determines whether or not this user can access other users' personal schedules and department schedules, and displays only the schedules that can be accessed as shown in FIG. Alternatively, the display unit 5 may be instructed.

  At this time, the determination unit 4 may be configured to specify a user who is operating the schedule management device 1 based on information for specifying a user input by the input unit 3 or the like. In this case, the determination unit 4 functions as a user specifying unit. In this case, the determination unit 4 may be configured to identify the user by any existing method. For example, the user ID and password may be configured to be input to the user via the input unit 3 in advance. For example, the determination unit 4 may specify a user by reading an ID card or the like assigned to each user with a card reader (not shown).

  Moreover, when the change content of a schedule is input via the input part 3, the determination part 4 will determine the other schedule affected by this change. Specifically, the determination unit 4 detects another schedule that has a dependency relationship with the changed schedule. Then, the determination unit 4 instructs the display unit 5 to display the determined other schedule. By performing such display, a user who has input a change in schedule can easily determine what kind of influence the change input by himself has on other schedules. In addition, the determination unit 4 instructs the display unit 5 to display a warning or the like to the user related to the other determined schedule. At this time, for example, the determination unit 4 stores a warning target user and the warning contents, and when the user logs in to the schedule management device 1, the warning contents regardless of the instruction contents by the user. May be displayed. The content of the warning may be, for example, a form that displays a changed schedule, a schedule that has a dependency relationship with the schedule, and that is related to the user.

[Display section]
The display unit 5 is configured using a display device such as a CRT (Cathode Ray Tube) display or a liquid crystal display. The display unit 5 performs display according to the content instructed by the determination unit 4. The display unit 5 may be configured to perform display by reading the content instructed by the determination unit 4 from the schedule storage unit 2, or perform display based only on data received from the determination unit 4. It may be configured.

[Action / Effect]
According to the schedule management apparatus 1, each schedule regarding each project is hierarchized according to the use, and managed with relevance. Moreover, according to the schedule management apparatus 1, mutual relations are also stored for schedules related to different levels, different departments, and different users. Then, other schedules related to the schedule selected by the user are displayed. FIG. 7 is a diagram illustrating a display example according to the determination result by the determination unit 4. In FIG. 7, the schedule of “large schedule” as the company schedule, the schedule of “own part” indicating the department to which the user belongs, the schedule of the individual user, and the schedule of other parts related to the schedule of the user personal Is displayed. In this way, the other schedule displayed may be a schedule related to another hierarchy, or a schedule related to another part or another individual. For this reason, the user can easily determine another schedule related to a certain schedule.

Conventionally, an unspecified person can see all the schedules, and there has been a problem in terms of security. That is, access control related to the schedule has not been realized. On the other hand, according to the schedule management device 1, the access level is set for each schedule, and only the schedule according to the access level of the user is displayed. For this reason, the access control regarding a schedule is implement | achieved and it becomes possible to maintain security.
