JP-A-8-137949

FIG. 15 is a diagram showing an example of a Gantt chart display screen, and FIGS. 16 and 17 are diagrams showing an example of a Gantt chart change screen in FIG. In FIG. 16, elements similar to those in FIG.
In the Gantt chart display screen 1000 of FIG. 15, reference numerals 1001 to 1003 are resource rows indicating one process, for example. Reference numerals 1004 to 1006 are bars indicating work periods of persons who are involved in the processes related to the corresponding resource rows 1001 to 1003. Reference numerals 1010 to 1014 will be described later.

  Here, it is assumed that the bars 1004 and 1005 on the Gantt chart display screen 1000 shown in FIG.

  That is, as shown in FIG. 16, the bars 1004 and 1005 are moved to the resource row 1003. Then, since a part of the period indicated by the bars 1004 to 1006 overlaps, as shown in the Gantt chart display screen 1100, the bars 1104 to 1106 which are the bars at the respective movement destinations overlap with the resource row 1103. turn into. In the example shown on the Gantt chart display screen 1100, a part of the bar 1104 (the destination bar of the bar 1004) is hidden behind the bar 1105, and a part of the bar 1105 (the bar 1006) is moved to the bar 1106 (the movement of the bar 1005). Since it is hidden behind the previous bar), the work periods of the bars 1104 and 1105 are unknown. Note that no bars are displayed in the resource rows 1101 and 1102.

  Here, as shown in the Gantt chart display screen 1200 shown in FIG. 17, a method of clarifying the work periods of the bars 1204 and 1205 by constricting each bar like bars 1204 to 1206 can be considered. However, as shown in the Gantt chart display screen 1200, the characters described in the bars 1204 to 1206 become smaller, or part of the characters may be hidden if the size of the characters is not changed. There's a problem. The resource rows 1201 and 1202 are the same as the resource rows 1101 and 1102 in FIG.

  Furthermore, when the number of bars displayed in one resource row increases, each bar becomes like a line, and there is a problem that it is difficult to perform bar operations such as dragging the bar.

  In view of the above problems, an object of the present invention is to make information of each bar easy to see and operate even if a large number of bars are displayed in one resource row.

In order to solve the above problems, according to the present invention, the storage unit of the Gantt chart display device associates the height of a bar in the Gantt chart with the height of a resource row that is a rectangular area in which the bar is displayed. And the processing unit of the Gantt chart display device acquires all the bar heights corresponding to the resource rows to be processed from the storage unit, adds the acquired bar heights, A predetermined value is calculated as the height of the added bar, and a value obtained by further adding the calculated value as the height of the resource row, and the height of the resource row in the storage unit is updated to the calculated height of the resource row. Then, the resource line is displayed on the display unit according to the height of the updated resource line, and the bar corresponding to the resource line is displayed in the resource line.
Other means will be described in an embodiment described later.

  According to the present invention, even if a large number of bars are displayed in one resource row, the information of each bar is easy to see and can be operated easily.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. In this embodiment, as described with reference to FIG. 15, “bar” is a rectangle representing a work period in the Gantt chart, and “resource row” is displayed as a “process” in FIG. 15.

(processing)
Next, the Gantt chart display process shown in the first embodiment will be described along FIGS. 3 to 5 with reference to FIGS. 1 and 2. According to the processing shown in FIG. 3 to FIG. 5, as will be described later in FIG. 6, by changing the height of the resource line, even if the moved bars overlap, the height of the bars does not change and is described in the bars. It is easy to visually recognize the information and the bar is easy to operate.

FIG. 3 is a flowchart showing the flow of the Gantt chart display process according to the first embodiment. In the flowchart in the present embodiment, processing surrounded by a broken line indicates processing by a human hand.
First, when the Gantt chart display program is activated and the processing unit 11 is activated, the determination unit 116 determines whether a “Gantt chart creation” button (not shown) displayed on the display unit 14 is selected and input via the input unit 13. By determining whether or not to create a Gantt chart (S101).
When creating a Gantt chart as a result of Step S101 (S101 → Yes), the user performs Gantt chart creation processing via the input unit 13 (S102), and the processing unit 11 advances the processing to Step S105. In step S102, the input processing unit 111 acquires information on the start date / time, end date / time, and bar height of each bar of the created Gantt chart from the input unit 13, and further issues a bar ID for each bar. Then, the input processing unit 111 acquires the height of each resource row and the bar ID, and issues a resource row ID for each resource row. The storage processing unit 117 stores the bar ID, start date / time, end date / time, and bar height of each bar in the corresponding fields 141, 143 to 145 in the bar information 123 of the storage unit 12 as a set of information. Further, the storage processing unit 117 stores the resource row ID and the resource row height in each resource row in the corresponding columns 131 and 133 of the resource row information 122 of the storage unit 12 as a set of information. Then, the storage processing unit 117 stores the ID of the resource row (resource row ID) in which each bar is displayed in the column 146 and stores the display order of the bars in the resource row in the column 147.
The resource name and the bar name are input to the processing unit 11 via the input unit 13, and the storage processing unit 117 stores them in the resource name column 132 of the resource line information 122 and the bar name column 142 of the bar information 123, respectively. .

If no Gantt chart is created as a result of step S101 (S101 → No), for example, it is determined by determining whether or not an “edit” button (not shown) displayed on the display unit 14 is selected and input by the input unit 13 The unit 116 determines whether there is an editing work (S103).
As a result of step S103, when there is no editing work (S103 → No), the display processing unit 112 displays the content of the Gantt chart information 121 on the display unit 14 (S110).
If it is determined in step S103 that there is an editing operation (S103 → Yes), a bar editing operation is performed based on the information input via the input unit 13 (S104), and the processing unit 11 advances the processing to step S105. . The bar editing work includes moving the bar, copying the bar, changing the bar height, and the like. When the bar is moved, the input processing unit 111 causes the storage processing unit 117 to change the information in the column 146 of the bar information 123 of the storage unit 12 from the source resource row ID to the destination resource row ID. Further, the input processing unit 111 causes the storage processing unit 117 to update the order in the resource row of the column 147 in each bar. When the bar is copied, the input processing unit 111 generates a new bar ID row (record) in the bar information 123 of the storage unit 12, and stores each column 142-2 of the copy source bar information 123 in the storage processing unit 117. The information 145 is copied to the respective columns 142 to 145 of the generated line. Then, the input processing unit 111 stores the resource row ID in which the newly generated bar is displayed in the column 146 corresponding to the newly generated bar ID. Further, the input processing unit 111 updates or stores the order of each bar in the resource row in each bar ID column 147.
It is also possible to edit the copied bar by moving it or changing its length. When the bar height is changed, the input processing unit 111 causes the storage processing unit 117 to change the information in the bar height column 145 in the bar information 123 of the bar whose height has been changed.

  Next, the acquisition unit 113 acquires one row of resource row information 122 from the storage unit 12 (S105). Then, the processing unit 11 performs overlap check processing for checking whether or not there is an overlapping bar in the resource row based on the acquired resource row information 122 (S106). The process of step S106 will be described later with reference to FIG.

Next, the determination unit 116 determines whether there is an overlapping bar in the target resource row based on the result of step S106 (S107).
If there is no overlap as a result of step S107 (S107 → No), the processing unit 11 advances the process to step S109.
If there is an overlap as a result of step S107 (S107 → Yes), the processing unit 11 performs a resource row height changing process for matching the resource row height to the total value of the bar heights (S108). The process of step S108 will be described later with reference to FIG.

Then, the determination unit 116 determines whether or not processing has been completed for all resource rows in the resource row information 122 of the storage unit 12 (S109).
As a result of step S109, when all the resource rows are not completed (S109 → No), the processing unit 11 returns the processing to step S105, and the acquisition unit 113 acquires the next resource row information 122 for one row.
As a result of step S109, when all the resource rows are completed (S109 → Yes), the display processing unit 112 displays the Gantt chart information 121 of the storage unit 12 on the display unit 14 (S110).

FIG. 4 is a flowchart showing a flow of overlap check processing according to the first embodiment. The process shown in FIG. 4 is the process in step S106 of FIG.
First, the acquisition unit 113 acquires all the rows of the bar information 123 having the resource row ID included in the acquired resource row information 122 in the column 146 (S201). At this time, the acquisition unit 113 may acquire the start date and time and the end date and time corresponding to the corresponding bar ID from the bar information 123.
Then, the duplication check unit 115 checks whether or not there are overlapping bars by checking the date and time of both ends of each acquired bar (S202). That is, the duplication check unit 115 overlaps (duplicates) by checking whether there is another bar with the start date and time or the end date and time between the start date and time and the end date and time in each bar. Check if there is a bar. Then, the duplication check unit 115 outputs the result of step S202 (S203).

FIG. 5 is a flowchart showing the flow of the resource row height changing process according to the first embodiment. The process shown in FIG. 5 is the process in step S108 of FIG.
First, the acquiring unit 113 acquires the height of each bar from the bar height column 145 in the bar information 123 having the target resource row ID in the column 146 (S301).
Next, the adding unit 114 adds all the acquired bar heights (S302). Next, the adding unit 114 calculates a new resource row height by adding a predetermined value (a margin of the resource row in the vertical direction of the bar) to the result of step S302 (S303). Then, the storage processing unit 117 updates the resource row height information in the corresponding resource row information 122 to the calculated resource row height (S304), thereby changing the resource row height.

(Screen example)
Next, the Gantt chart display screen according to the first embodiment will be described with reference to FIGS.
FIG. 6 is a diagram showing an example of a Gantt chart display screen when the technique of the first embodiment is applied when the bar is moved as described above with reference to FIGS. 15 to 17.
In the Gantt chart display screen 200, the height of the resource row 203 corresponding to the step 3 is changed to match the total height of the bars 204 to 206 collected in the resource row 203. Thereby, the information described in the bars 204 to 206 remains visible, and it is easy to perform an operation such as dragging. By doing so, even if a large number of bars overlap in the resource row, the bar information can be visually recognized, and the bars can be easily operated. Note that since there are no bars in the resource rows 201 and 202, the resource row height remains unchanged.

FIG. 7 is a diagram illustrating an example of a Gantt chart display screen when a bar is copied.
In the Gantt chart display screen 300, one of the bars 304 is displayed in the resource row 301, two bars 305 and 306 are displayed in the resource row 302, and bars 307 to 309 are displayed in the resource row 303. Are displayed. In the information displayed in each of the bars 304 to 309, a bar (for example, “C” in the bar 304 of the resource row 301 and the resource row 303 is duplicated with the bar information displayed in the other resource rows). "C") in the bar 308 indicates that the data was copied from one to the other. In addition, since the copied bar can be edited such as moving within the resource row, as shown in FIG. 7, the copy source bar and the copy destination bar are not necessarily the start date and time and end date and time. Do not always match. Further, even if there is no overlap at the time of copying, it may be overlapped by a subsequent bar editing operation. According to the first embodiment, even in such a case, the height of the resource row in which the copied bar is displayed can be changed.
In FIG. 7, the height of each of the resource rows 301 to 303 is a height that matches the total height of the bars. As a result, as in FIG. 6, the information described in the bars 304 to 309 remains visible and it is easy to perform operations such as dragging.

FIG. 8 is a diagram illustrating an example of a Gantt chart display screen when the bar height is changed.
8, elements similar to those in FIG. 6 are given the same reference numerals and description thereof is omitted.
FIG. 8 shows an example in which the heights of the bars 204 to 206 on the Gantt chart display screen 200 are changed as the bars 404 to 406 on the Gantt chart display screen 400, respectively. Such a change is a process performed in the bar editing operation in step S104 of FIG.
As shown in FIG. 8, even if the height of a specific bar 405 is increased for the purpose of emphasis or the like, and the height is decreased like the other bars 404 and 406, the height of the corresponding resource row 403 is The height matches the total value of the bars 404-406. Note that the resource rows 401 and 402 do not have a bar as in the resource rows 201 and 202, and therefore the resource row height remains unchanged.

FIG. 9 is an example of a Gantt chart display screen when the bar position is changed in the same resource row.
In FIG. 9, the same elements as those in FIG.
FIG. 9 shows an example in which the resource row 503 of the Gantt chart 500 is obtained by exchanging the bars 404 and 406 in the resource row 403 of the Gantt chart display screen 400 with each other. Moreover, such a change is a process performed in the bar editing operation in step S104 of FIG.

(Second Embodiment: Device Configuration)
FIG. 10 is a diagram illustrating a configuration example of a Gantt chart display device according to the second embodiment.
The Gantt chart display device 1a shown in FIG. 10 is different from the Gantt chart display device 1 shown in FIG. 1 in the following points.
The first point is that the information stored in the resource row information 122a in the Gantt chart information 121a of the storage unit 12a is different from the resource row information 122 shown in FIG. The resource line information 122a will be described later with reference to FIG.
The second point is that a counting unit 118 and a color changing unit 119 are added to the processing unit 11a.
The counting unit 118 has a function of counting the number of bars in the resource row. The color changing unit 119 has a function of changing the color of the resource row.

(Resource line information)
FIG. 11 is a diagram illustrating an example of resource row information according to the second embodiment.
The resource line information 122a shown in FIG. 11 is different from the resource line information 122 shown in FIG. 2A in that a color for storing information about the color when the resource line is displayed on the display unit 14 (see FIG. 10) is stored. The information column 136 is added.
In the example shown in FIG. 11, the resource row information 122a is sorted in descending order of the number of bars to which it belongs, but the sorting need not be performed. The number of bars to which the member belongs is calculated by the counting unit 118 counting the number of bar IDs having the corresponding resource row ID in the column 146.

(processing)
Next, the Gantt chart display process shown in the second embodiment will be described along FIG. 12 with reference to FIGS. 10 and 11. According to the processing shown in FIG. 12, as described later in FIG. 13, the color of the resource row can be changed in accordance with the number of bars displayed in the resource row. Management of the number of workers (corresponding to the bar).

FIG. 12 is a flowchart showing the flow of Gantt chart display processing according to the second embodiment. In FIG. 12, the same steps as those in FIG.
After the processing of step S108, the counting unit 118 counts the number of bars in the resource row by counting the number of bar IDs having the target resource row ID in the column 146 (S401). . That is, in this embodiment, the number of bar IDs having the resource row ID in the column 146 is information regarding the number of bars in the resource row.
Then, the color changing unit 119 changes the color of the resource row by changing the information in the color information column 136 of the target resource row information 122a to the color information corresponding to the number counted in step S401. (S402). The correspondence information between the number of bars in the resource row and the color information is stored in the storage unit 12a in advance.

  Note that the counting unit 118 stores the number of counted bar IDs and the corresponding resource row ID, and after “Yes” is determined in step S109, the processing unit 11a stores the stored bar IDs. Each row of the resource row information 122a may be sorted based on the number of. The resource row information 122a is not changed. For example, when the “sort in ascending order” button (not shown) displayed on the display unit 14 is selected and input by the input unit 13, the counting unit 118 displays each resource row ID in the column. The display processing unit 112 may display the Gantt chart display screen on the display unit 14 by counting the number of bar IDs included in 146 and sorting based on the result of the counting.

(Screen example)
FIG. 13 is a diagram illustrating an example of a Gantt chart display screen according to the second embodiment.
In the Gantt chart display screen 600, the resource rows 601 to 603 are displayed in different colors depending on the number of bars in the resource rows 601 to 603 (in FIG. 13, the difference in color is expressed by the difference in hatching). ).
In this way, by changing the color of the resource line in accordance with the number of bars displayed in the resource line, for example, the work manager can select the worker (on the bar) for the process (corresponding to the resource line). Equivalent number) becomes easier to manage.
Note that the Gantt chart display screen 600 shown in FIG. 13 is sorted and displayed in descending order of the number of displayed bars.

FIG. 14 is a diagram showing an example of a Gantt chart display screen in which only the places where the number of overlapping bars is a predetermined number or more are emphasized.
In the example of FIG. 14, an area 704 where three or more bars overlap is displayed in an highlighted manner. In the resource row 701 of the Gantt chart display screen 700, a portion where three or more bars overlap is highlighted as an emphasis region 704. The resource rows 702 and 703 are not highlighted because there are no places where three or more bars overlap.

The Gantt chart display screen 700 shown in FIG. 14 is performed in the following procedure, for example.
For example, when an unillustrated “overlapping overlap region emphasis” button displayed on the display unit 14 is selected and input by the input unit 13, the duplication check unit 115 refers to the resource line information 122 and the bar information 123, Check the start date and end date of the bar for each resource row. And the duplication check part 115 detects the period when more than the set number of bars overlap. The display processing unit 112 highlights the detected period in the corresponding resource row.
By doing so, the work manager can easily grasp the period during which work is concentrated.

  The processing units 11 and 11a and the respective units 111 to 119 shown in FIG. 1 and FIG. 10 each include a Gantt chart display program stored in a ROM (Read Only Memory) (not shown) or a HD (Hard Disk) (not shown).
