Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for deriving a job net having a preceding and succeeding relationship including a day-to-day job net and a job net that is a base point, a method for deriving a job net in the vicinity of the job net, and a method for displaying the related diagram using a graphical user interface (GUI) It is about.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a method of clearly displaying a relationship between a preceding and succeeding job / job net using a link line is generally performed. However, in the case of an operation management system in which a large number of job nets are intricately related, it is not easy to pick out the preceding and succeeding relations for one job net from the overall view.
[0003]
Further, there is no technique for adding a concept of a time axis to a preceding / following relationship and displaying a preceding / following relationship diagram that takes into account a preceding / following relationship across dates, that is, a preceding / following relationship including a day interval.
[0004]
Recently, we extracted the job nets necessary for business from mainframe jobs, introduced the concept of net groups, where the set of job nets is a unit, and established the prior / following relationship between job nets belonging to the net group Although a display method has been devised, if a job net belonging to a net group has a predecessor-related relationship from a job net that does not belong to the corresponding net group, an external relationship is displayed on the job net icon. For job nets that are provided with a mark indicating that they are related to the day interval and externally, the job net names are displayed in a list format.
[0005]
[Problems to be solved by the invention]
However, in the display method according to the conventional method described above, it is not possible to acquire all of the preceding and succeeding related information for the target job net in one operation, and in order to acquire related information for the job net of the preceding and succeeding related destination A series of operations is also required for the job net, and in the case of a complex system, acquiring related information related to the target job net is a costly operation.
[0006]
An object of the present invention is to solve such a problem and extract all preceding and succeeding related job nets that can be traced from a job net that is a base point from a specified range, and also spans dates, that is, a day interval. The related neighborhood of job nets that are extracted from the specified range for the preceding and succeeding related job nets that have a clear and easy-to-understand display of the preceding and succeeding related relationships of the target job net To provide a method for deriving and displaying a job net.
[0007]
[Means for Solving the Problems]
  To achieve the above objective,A method for deriving a job net related to a job net according to the present invention includes: a job net serving as a base point; and a preceding / successful job net that is related to a preceding / following job net including a day interval with respect to the base job net. Within the specified number of neighbors of the preceding and succeeding job nets within the specified preceding and succeeding number range, and the preceding job net and the succeeding job net as the neighboring job nets that can be traced from each job net The preceding job net and the subsequent job net are derived.
  According to the present invention, a method for displaying related job nets of job nets is a method for creating a net group composed of a set of job nets as a GUI display unit and deriving related job nets of the job nets using the net group. A job net in the vicinity of a job net serving as a base point obtained based on the above is displayed.
  When a job net including a day interval exists, the value of the day interval is displayed as a subscript between job nets.
  Further, when there is a job net including a day interval, the relationship between the job nets is depicted in a three-dimensional view including the coordinate axis of the day interval, and a plurality of job nets having the same job net name and different day intervals are displayed. Are displayed at different positions in the coordinate axis direction.

As shown in FIG. 3B, the initial scheduled date 161, the preceding job net name 162, and the succeeding A job net name 163 and a day interval 164 are included.
[0016]
Next, job nets that can be traced from the preceding / following related information of the job net that is the base point and the information of the specified display range are extracted, and a net group having these job nets as constituent elements (that is, a dummy net group) ) And transmitting information necessary for display to the client 3 will be described with reference to FIGS.
[0017]
FIG. 4 is a sequence diagram showing a communication procedure between the client 3 and the server 2 when the related neighborhood job net display process of the job net as the base point is performed.
[0018]
In FIG. 4, first, a dummy net group creation request 200 is made from the client 3 to the server 2 (step S101). In this dummy net group creation request 200, information communication from the client 3 to the server 2 is performed by the protocol shown in FIG. 5A. That is, the base job net name shown in FIG. 201, initially scheduled date 202 of the job net, designated preceding number 203 designated as a preceding range, designated succeeding number 204 designated as a following range, designated neighborhood number 205 designated as a neighborhood range, designated as a range of day intervals A total of six items of information on the designated number of specified day intervals 206 are transmitted from the client 3 to the server 2. Here, the originally scheduled date 202 can be omitted, and is omitted when requesting for master information. In the server 2, a dummy net group is created from the information, and information including one item of the dummy net group name 207 (FIG. 5A) uniquely indicating the dummy net group is transmitted to the client 3 (step S102).
[0019]
The client 3 makes a dummy net group component job net information acquisition request 210 based on the received dummy net group name (step S103). In the dummy net group component job net information acquisition request 210, information communication between the client 3 and the server 2 is performed by the protocol shown in FIG. 5B. That is, the network shown in FIG. Information on a total of two items of the group name 211 and the initial scheduled date 212 is transmitted from the client 3 to the server 2. Here, the initial scheduled date 212 can be omitted, and is omitted when requesting the master information. The server 2 extracts information on the corresponding job net from the mainframe managed information file 21 and the server managed information file 22 shown in FIG. 1 using these pieces of information as keys, and the job net shown in FIG. A total of four items of job net information including name 213, X coordinate 214, Y coordinate 215, and job net detailed information 216 are transmitted to client 3 as a response to request 210 (step S104). At this time, the number of records to be transmitted is equal to the number of job nets that are constituent elements of the dummy net group.
[0020]
The client 3 performs a preceding job net information acquisition request 220 for the corresponding job net from the received information of the job net (step S105). In the preceding job net information acquisition request 220, information communication between the client 3 and the server 2 is performed according to the protocol shown in FIG. 5C. That is, the job net name 221 shown in FIG. Information on a total of two items of the originally scheduled date 222 is transmitted from the client 3 to the server 2. Here, the initial scheduled date 222 can be omitted, and is omitted when requesting the master information. The server 2 extracts the information of the corresponding preceding job net from the information file 21 under the management of the mainframe using these information as a key, and displays a total of two items, the preceding job net name 223 and the day interval 224 shown in FIG. Is sent to the client 3 as a response to the request 220 (step S106). At this time, the number of records to be transmitted is equal to the preceding number of the specified job net.
[0021]
The client 3 makes a subsequent job net information acquisition request 230 for the corresponding job net from the received information of the job net (step S107). In the subsequent job net information acquisition request 230, information communication between the client 3 and the server 2 is performed by the protocol shown in FIG. 5D. That is, the job net name 231 shown in FIG. Information on job nets of a total of two items on the originally scheduled date 232 is transmitted from the client 2 to the server 2. Here, the initial scheduled date 232 can be omitted, and is omitted when requesting the master information. The server 2 extracts the information of the corresponding subsequent job net from the information file 21 under the management of the mainframe using the information of the job net as a key, and the information of a total of two items of the subsequent job net name 233 and the day interval 234 is requested 230. Is transmitted to the client 3 as a response to (step S108). At this time, the number of records to be transmitted is the number of subsequent records of the specified job net.
[0022]
By executing the above steps S101 to S108, the client 3 can acquire all necessary information, and can display related neighboring job nets of the job net that is the base point.
[0023]
FIG. 6 is a flowchart showing a procedure for creating a dummy net group and its components.
[0024]
In the figure, as a procedure for creating a dummy net group and its constituent elements, first, the server 2 receives a request 200 (FIG. 4) from the client 3 and creates a dummy net group (step S201).
[0025]
Next, information on the preceding job net within the designated range that can be traced from the job net that is the base point is acquired (step S202). The acquired information on the preceding job net is once secured on the memory. If there are duplicate job nets in this process, they are combined into one. Similarly, information on subsequent job nets within a specified range that can be traced from the base job net is also acquired (step S203). The acquired information of the succeeding job net is once secured on the memory, similarly to the information of the preceding job. If there are duplicate job nets in this process, they are combined into one.
[0026]
Next, information on the preceding job nets within the designated neighborhood range that can be traced is obtained for all the preceding job nets and subsequent job nets that are obtained in this way (step S204). The acquired information on the preceding job net is once secured on the memory. If there are duplicate job nets in this process, they are combined into one. Similarly, information on subsequent job nets within a specified neighborhood range that can be traced is also obtained for all the preceding job nets and subsequent job nets that are obtained (step S205). The acquired subsequent job net information is once secured in the memory. If there are duplicate job nets in this process, they are combined into one.
[0027]
Finally, the job net information stored in the memory is stored in the server-managed information file 22 (FIG. 1) (step S206).
[0028]
Thus, the creation of the dummy net group and its constituent elements is completed.
[0029]
Next, a specific example of each step in FIG. 6 will be described.
[0030]
First, details of the processing in step S201 in FIG. 6 will be described.
[0031]
The information on the dummy net group created in step S201 is stored in the server-managed information file 22 in FIG. The stored information is composed of net group master information 130 shown in FIG. 2C and net group schedule information 170 shown in FIG. 3C. The net group master information 130 is shown in FIG. As shown in FIG. 3C, it has a net group name 131, and the net group schedule information 170 has an initial scheduled date 171 and a net group name 172 as shown in FIG.
[0032]
FIG. 7 is a flowchart showing a specific example of the procedure (step S202) regarding the acquisition of the preceding job net information in FIG.
[0033]
In the figure, first, processing for selecting a candidate for a preceding job net for a base job net is performed in steps S301 to S303. That is, first, it is determined whether or not the job net to be determined (hereinafter referred to as the target job net) exceeds the range from the designated base job net (step S301). If it is determined that the specified range is exceeded, the processing for the target job net is terminated. In other cases, it is determined whether or not the target job net has already been subjected to determination processing (step S302). If it is determined that such determination processing has been performed, the determination processing for determining whether or not the job net is a preceding job net is terminated. In other cases, the information on the target job net is secured in the memory to be processed (step S303). In this way, candidates for the preceding job net are selected, and at the same time, the number of candidates for the preceding job net (number of information) is also detected.
[0034]
Next, information on the preceding job net secured in the memory (information on the preceding job net) is acquired from the main frame management file 21 (FIG. 1) (step S304). In order to determine whether or not it is a corresponding preceding job net, the number of determinations is counted by the counter for each job net determination. It is determined whether or not the count value has reached the acquired number of information (that is, the number of target job nets secured in the memory) (step S305). When this count value reaches the number of acquired information, all processes for the preceding job net are completed. In other cases, the preceding range under investigation is advanced by 1, and the next target job net secured in the memory is set as the determination target (step S306). Here, it is determined whether or not the information acquisition of the preceding job net is acquisition of master information (step S307), and if it is on the master, the process proceeds to step S309 as it is, but acquisition of schedule information is acquired instead of acquisition of master information. If so, the originally scheduled date is changed by the acquired day interval, the day interval range under investigation is also changed (step S308), and the process proceeds to step S309.
[0035]
In step S309, the next preceding job net information is recursively acquired based on the above processing, and the count value of the counter is set to 1 when the recurring processing for acquiring the preceding job net information is completed. Proceeding (step S310), the process returns to step S305 for determining whether or not the counter has reached the number of pieces of information acquired, and the above processing is repeated for the information of the new preceding job net.
[0036]
As described above, it is possible to acquire the information of the preceding job net that can be traced from the job net that is the base point.
[0037]
Note that the algorithm shown in FIG. 7 is the same for the acquisition of the information of the subsequent job net in step S203 of FIG. As a result, it is also possible to acquire information on the succeeding job net that can be traced from the job net that is the base point.
[0038]
FIG. 8 is a flowchart showing a specific example of the procedure (step S204) relating to the acquisition of preceding job net information (acquisition of preceding neighbor information) of the destination job net in FIG.
[0039]
In the figure, first, it is determined whether or not the preceding job net to be traced has exceeded the range in the vicinity of the designated job net (step S401). As a result, when it is determined that the specified range is exceeded, the processing for the preceding job net to be traced is terminated. In other cases, it is determined whether or not the preceding preceding job net has already undergone the processing shown in FIG. 8 (step S402). If it is determined that it has been processed, the processing for the preceding job net to be traced is terminated. In other cases, it is determined whether the investigated range of the preceding preceding job net is larger than the processed range (step S403). If it is determined that the range is larger than the processed range, the process for the preceding job net to be traced is terminated. In other cases, the information of the preceding job net is secured in the memory to be processed (step S404). In this way, the above determination process for each preceding destination job net is sequentially performed, and the processed preceding job net is secured in the memory. Also in this case, the number of pieces of information stored in the memory Is also secured.
[0040]
Next, information on the preceding job net for the tracing destination preceding job net is acquired from the mainframe management file 21 (step S405). In order to determine whether or not there is a corresponding preceding job net for the number of acquired preceding job nets, each time the preceding job net is determined, the number of determination processes is counted by a counter. Then, it is determined whether or not the count value of the counter has reached the acquired number of information (step S406). When the count value reaches the acquired number of information, the process for the preceding preceding job net is terminated. In other cases, the preceding range under investigation is advanced by 1, and the next preceding job net is set as a processing target (step S407). Here, it is determined whether or not the information acquisition of the preceding destination job net is the master information (step S408). If it is the mask information, the process proceeds to step S410 as it is. If it is acquisition, the initial scheduled date is changed by the acquired day interval, the day interval range under investigation is also changed (step S409), and the process proceeds to step S410.
[0041]
In step S410, based on the above processing, information on the next preceding destination job net is acquired recursively, and when the recursive processing for acquiring the preceding destination job net information ends, the count value of the counter Is advanced by 1 (step S411), the process returns to step S406 for determining whether or not the count value of the counter has reached the number of acquired information, and the above-described processing is repeated for the preceding preceding job net information. .
[0042]
As described above, information on the preceding job net that can be traced from the preceding preceding job net can be acquired.
[0043]
Note that the algorithm shown in FIG. 8 is the same for the acquisition of information on the subsequent job net to be traced in step S205 in FIG. As a result, information on the succeeding job net that can be traced from the destination job net can also be acquired.
[0044]
Next, details of the processing in step S206 of FIG. 6 will be described.
[0045]
In step S206, based on the dummy net group created in step S201 and the information obtained in steps S202 to S205, information related to the net group and the job net that is a constituent element is obtained from the server-managed information file 22 (FIG. 1). To store. This stored information is composed of net group-job net selection master information 140 and net group-job net selection schedule information 180.
[0046]
The net group-job net selection master information 140 includes a net group name 141, a job net name 142, an X coordinate 143, and a Y coordinate 144 as shown in FIG. As job net position information, a horizontal position is represented by an X coordinate 143 and a vertical position is represented by a Y coordinate 144. Further, as shown in FIG. 3D, the net group-job net selection schedule information 180 has an initial scheduled date 181, a net group name 182, a job net name 183, an X coordinate 184, and a Y coordinate 185. Yes.
[0047]
Next, the process of displaying with GUI on the basis of the transmitted information in the client 3 will be described with reference to FIGS.
[0048]
This display step consists of setting a map area, arranging a job net, drawing a link line, and displaying a day interval.
[0049]
First, as shown in FIG. 9A, a map area is set. This is to set a map area M for displaying job net icons and link lines, and the map area M uses a fixed value as an initial value. Here, as an example, the horizontal dimension is 13 with respect to the vertical dimension 7.
[0050]
Next, as shown in FIG. 9B, job nets are arranged. This is because each job net is mapped on the basis of the job net name 213 obtained by the dummy net group component job net information acquisition request 210 (FIG. 4) and its position information 214 and 215 (FIG. 5B). It is arranged in the area M. Here, a state where job nets A to F are arranged in the map area M is shown.
[0051]
Next, as shown in FIG. 9C, the link line is drawn and the day interval is displayed. This is because the preceding / following related information 223, 224, 233, 234 (FIGS. 5C and 5D) obtained by the preceding information acquisition request 220 of the job net and the subsequent information acquisition request 230 of the job net (FIG. 4). ) To draw a link line. The direction of the arrow of the link line is the direction from the preceding job net to the subsequent job net. Further, the date interval of the preceding job net is also obtained from the preceding / following related information. If the day interval is not 0, the value is attached to the icon of the preceding job net. In FIG. 9C, the day interval between job nets A and E is 1. If there are multiple job nets with the same job net name and different day intervals, the subscript day interval values are displayed separated by “,”. At that time, if a day interval is also included, the value of the day interval is added to the subscript. For example, if there are two job nets with the job net name “A”, one day interval is 0 and the other day interval is 1, “A_1,1"," A₂"
[0052]
FIG. 10 is a diagram showing a specific display example of the job nets related to the job net that is the base point.
[0053]
FIG. 10A shows a job net C as a base point, the job net C as a base point when the designated preceding number is set to 2, the designated succeeding number is set to 2, and the designated neighborhood number is set to 0. This is a display of related neighborhood job nets.
[0054]
In this case, only the preceding and succeeding job nets that can be traced directly from the job net C are displayed. For this reason, if there are other subsequent job nets in the preceding job nets A and B of the job net C, or if there are other preceding job nets in the subsequent job nets D, E, and F of the job net C, The job net is not displayed (the job net that is not displayed is indicated by a broken line).
[0055]
FIG. 10B shows the relationship between the job net as a base point when the job net C is set as the base job net, the designated preceding number is set to 2, the specified succeeding number is set to 2, and the specified neighborhood number is set to 2. This is a display of nearby job nets.
[0056]
Unlike the display in the case of FIG. 10A, the neighboring job nets that can be traced from the preceding / successful job nets A, B, D, and F that can be traced directly from the job net C are also displayed. The job net E has no job net that can be traced from now on). For this reason, the number of neighboring job nets (for example, job nets K, L, and M) that are two times the designated number of neighbors from the destination job net (for example, job net B) of job net C are also displayed. As a result, the job net related to the job net C can be grasped from the screen.
[0057]
FIG. 11 is a diagram showing a specific display example in the case where a job net including a day interval exists in the related neighboring job net of the base job net.
[0058]
FIG. 11A shows a job net C as a base job, job nets A and B as preceding job nets traced from the job net C, and D, E, and F as succeeding job nets traced from the job net C. A plan view of related job nets of job net C, which is a base point when G and I are subsequent job nets traced from job nets A and B, and H is a preceding job net traced from job net D, respectively. .
[0059]
In FIG. 11A, among the job nets A, D, and H including the day interval among the related neighboring job nets of the job net C serving as the base point, the value of the day interval is displayed as a subscript. If there are multiple job nets with the same job net name, the day interval values are displayed separated by “,”. For example, in the case of the job net D, the subscript “1” after “,” represents the day interval.
[0060]
FIG. 11B shows a three-dimensional view of the related neighboring job net of job net C serving as the base point.
[0061]
In FIG. 11B, the related neighborhood job including the day interval of the job net C serving as the base point, with the day interval set in the direction along the axis perpendicular to the paper surface (vertical axis) and the vertical axis direction information leading. The net is displayed to make it easier to understand. This display differs from the plan view display in the method for arranging job nets.
[0062]
A plane perpendicular to the vertical axis on which the job net C serving as the base point exists is defined as plane P_OAnd depending on the day interval, this plane P_OA plane parallel to the plane P_OSet up and down. For example, when there is a day interval in the preceding job net A when viewed from the job net C, the plane P_OPlane P above_PAnd the plane P_PJob net A is placed in These planes P_O, P_PThe position of the job net in FIG. 11 is a projection of the position displayed in FIG.
[0063]
Further, when viewed from the job net C as the base point, for example, when the succeeding job net F has a day interval, the plane P_OPlane P below_SAnd this plane P_SThe job net F is arranged in Again, plane P_SThe position of the job net in FIG. 11 is a projection of the position displayed in FIG. The plane P on which the job net C serving as the base point exists_OIs the horizontal axis.
[0064]
【The invention's effect】
As described above, according to the present invention, by specifying a job net name and the number of preceding / succeeding of the job net, the number of neighbors, and the number of day intervals from the client, it is possible to select from a large number of complicated job nets. Only relevant information related to the target job net can be extracted. Such related information includes information about the day interval, and it is possible to know the related information taking the time axis into consideration. In addition, by displaying the GUI, the related information can be expressed in an easy-to-understand manner.
