Description

  The present invention relates to a model analysis support program and a model analysis support apparatus. More specifically, the present invention relates to a model analysis support program, a model analysis support apparatus, and a storage medium that support a user to analyze a simulation model.

  In a simulation model in which a large number of processes are complicatedly entangled, it is preferable to reduce re-execution of processes. This is because model analysis becomes easier and development efficiency improves. A Design Structure Matrix (DSM) may be used to optimize the process.

  In the design structure matrix (DSM), dependency information between a plurality of elements is expressed in a matrix format. When there is a dependency between elements, a numerical value other than 0 is entered in the off-diagonal component of the design structure matrix (DSM). Various techniques have been developed to optimize this design structure matrix (DSM). Patent Document 1 discloses a product development process support system that reduces the repetitive work of the development process by rearranging the development process by calculation using a design structure matrix (DSM). This makes it possible to design a process with less process re-execution.

  However, even if the process design is more efficient by computation, the scale of the simulation model may be too large for the user to grasp the overall picture. In addition, the process design rearranged by calculation may not always be optimal. There are also cases where a user wants to handle a plurality of special processes as a group. As described above, in order to perform process design reflecting the design philosophy of the user, it is preferable to support the user so that the user can accurately grasp the dependency relationship between elements and the hierarchical relationship.

  The present invention has been made to solve the above-described problems of the prior art. In other words, the problem is that a model analysis support program and model analysis support that can display on the display unit a display diagram that expands a lower hierarchy or a display diagram that omits the dependency relationship between elements extracted from the simulation model. An apparatus and a storage medium are provided.

  The model analysis support apparatus according to the first aspect includes a control unit that causes a display unit to display a design structure matrix that expresses a dependency relationship between a plurality of elements. The control unit includes a plurality of elements, dependency relationship information between a dependency source element and a dependency destination element, a hierarchical structure in which some of the plurality of elements constitute one or more lower layers, and , And the expansion information that is either the expanded value for expanding and displaying the lower hierarchy or the default value for omitting the lower hierarchy for display, Expansion abbreviation information holding part that is held corresponding to the hierarchy of the element, a design structure matrix display part that displays the dependency relationship between elements as a design structure matrix on the display part, and the dependency source element as the rear end of the arrow and the dependency A relationship diagram display unit for displaying on the display unit as a relationship diagram with the previous element as the tip of the arrow, a display diagram setting unit for setting which display diagram of the design structure matrix or the relationship diagram is displayed on the display unit, Have The design structure matrix display unit displays the design structure matrix in which the lower hierarchy is expanded on the display unit when the expansion omission information of the lower hierarchy held by the expansion omission information holding unit is an expanded value. When the expansion omission information of the lower hierarchy held by the expansion omission information holding unit is an omission value, a design structure matrix in which the lower hierarchy is omitted is displayed on the display unit. Then, when the expansion omission information of the lower hierarchy held by the expansion omission information holding unit is the expansion value, the relationship diagram display unit displays the relationship diagram in which the lower hierarchy is expanded on the display unit, and the expansion omission is performed. When the expansion omission information of the lower hierarchy held by the information holding unit is a default value, a relationship diagram in which the lower hierarchy is omitted is displayed on the display unit.

  This model analysis support apparatus can display two types of display diagrams, a design structure matrix and a relationship diagram showing a processing flow, on the display unit. Then, both the design structure matrix and the relationship diagram can be displayed on the display unit in a state where lower layers are appropriately expanded or folded and omitted. Therefore, the user can examine the simulation model by displaying the lower hierarchy in detail as appropriate while grasping the overall image of the simulation model. Of course, when the design structure matrix is displayed, each process can be exchanged.

  The model analysis support apparatus according to the second aspect includes a display method receiving unit that receives a display method of a display diagram to be displayed on the display unit as an expansion omitted input value, and an expansion omitted based on the expansion omitted input value received by the display method receiving unit. A development abbreviation information changing unit that changes the development abbreviation information held by the information holding unit. Further, the expansion omission information change unit displays the expansion omission information of the lower hierarchy when the expansion omission input value in the lower hierarchy received by the display method reception unit is a value indicating that the expansion omission is displayed. If the expansion omission input value in the lower hierarchy received by the display method receiving unit is a value indicating that the display is omitted, the expansion omission information of the lower hierarchy is changed to the default value. In the display diagram displayed on the display unit, even when there are a large number of lower layers, it is possible to easily switch between the display of the expanded state and the display of the omitted state for each of the lower layers. Therefore, the user can more suitably study the simulation model.

  In the model analysis support apparatus according to the third aspect, the display method accepting unit accepts, as a display diagram input value, either the design structure matrix or the relationship diagram as the display diagram to be displayed on the display unit. The display diagram setting unit is configured to display the design structure matrix on the display unit by the design structure matrix display unit when the display diagram input value in the lower hierarchy received by the display method reception unit corresponds to the design structure matrix. When the display diagram input value in the lower hierarchy received by the display method receiving unit corresponds to the relationship diagram, the relationship diagram display unit is configured to display the relationship diagram on the display unit. . Thereby, it is possible to easily switch between the design structure matrix and the relationship diagram as a display diagram to be displayed on the display unit.

  The model analysis support program according to the fourth aspect is for causing a computer to execute as a model analysis support apparatus for displaying a design structure matrix expressing a dependency relationship between a plurality of elements on a display unit. In this model analysis support program, a plurality of elements, dependency information between a dependency source element and a dependency destination element, and a part of the plurality of elements constitute one or more lower layers. Dependency information acquisition function that acquires the hierarchical structure, and expansion omitted information that is either an expanded value for expanding and displaying a lower hierarchy or an abbreviated value for displaying by omitting a lower hierarchy , An expanded omission information holding function that is held corresponding to the lower hierarchy, a design structure matrix display function that displays a dependency relationship between elements as a design structure matrix on the display unit, and a dependency source element at the end of the arrow In addition, the relationship diagram display function to display on the display unit as a relationship diagram with the dependent element as the tip of the arrow, and the display diagram setting to set which display diagram of the design structure matrix or relationship diagram to be displayed on the display unit Function and realized It is of the order. The design structure matrix display function displays the design structure matrix in which the lower hierarchy is expanded on the display unit when the expansion omission information of the lower hierarchy held by the expansion omission information holding function is an expanded value. This is a function for displaying, on the display unit, the design structure matrix in which the lower layer is omitted when the lower layer expansion omitted information held by the development omitted information holding function is a default value. The relation diagram display function displays a relation diagram in which the lower hierarchy is expanded on the display unit when the expansion omission information of the lower hierarchy held by the expansion omission information holding function is an expanded value, and omits the expansion. This is a function for displaying, on the display unit, a relationship diagram in which the lower hierarchy is omitted when the expansion omission information of the lower hierarchy held by the information holding function is a default value.

  The model analysis support program according to the fifth aspect includes a display method reception function that receives a display method of a display diagram to be displayed on the display unit as an expansion omitted input value, and an expansion omitted based on the expansion omitted input value received by the display method reception function. An expansion omission information change function for changing the expansion omission information held by the information holding function is realized. Then, when the expansion omission information change function is a value indicating that the expansion omission input value in the lower hierarchy input by the display method input function is expanded and displayed, the expansion omission information of the lower hierarchy is displayed as the expansion value. If the expansion omission input value in the lower hierarchy input by the display method input function is a value indicating that the display is omitted, the expansion omission information in the lower hierarchy is changed to the default value.

  In the model analysis support program according to the sixth aspect, the display method accepting function accepts, as a display diagram input value, either a design structure matrix or a relation diagram as a display diagram to be displayed on the display unit. The function is to set the design structure matrix to be displayed on the display section by the design structure matrix display function when the display diagram input value in the lower hierarchy accepted by the display method acceptance function corresponds to the design structure matrix. When the display diagram input value in the lower hierarchy received by the display method receiving function corresponds to the relationship diagram, the relationship diagram display function is set to display the relationship diagram on the display unit.

  The model analysis support program according to the seventh aspect realizes a dependency relationship update function for updating dependency relationship information. Here, there are at least two types of elements: a processing element having a process to be executed and a connecting element having only connection information for connecting the processing elements without having a process to be executed. The dependency relationship information has a dependency value indicating the degree of strength of the dependency between the dependency source element and the dependency destination element. The dependency update function changes the dependency value between the connection elements and the processing elements so that the dependency value between the connection elements is larger than the dependency value between the connection elements. The dependency relationship value is changed to a value larger than the dependency relationship value between the connection element and the processing element. While reducing the dependency weight related to the connection element, increase the dependency weight related to the processing element. Therefore, the user can study the simulation model in a state in which the dependency relation regarding the processing element that performs the actual processing is emphasized.

  In the model analysis support program according to the eighth aspect, the relationship diagram display function displays the relationship diagram on the display unit by increasing the thickness of the arrow as the dependency value increases. This makes it possible for the user to grasp the dependency relationship between elements in a visually comprehensible manner. Therefore, the user can more suitably study the simulation model.

  The storage medium according to the ninth aspect stores any of the above-described model analysis support programs and is readable by a computer.

  According to the present invention, a model analysis support program, a model analysis support device, and a display unit that can display a display diagram in which a lower hierarchy is expanded or a display diagram in which a lower hierarchy is omitted with respect to the dependency relationship between elements extracted from a simulation model, A storage medium is provided.

It is a schematic block diagram which shows the structure of the hardware of the model analysis assistance apparatus which concerns on embodiment. It is a block diagram for demonstrating the structure of the control part of the model analysis assistance apparatus which concerns on embodiment.

It is a figure which shows the expanded design structure matrix (DSM). It is a figure which shows the omitted relationship diagram. It is a figure which shows the expanded relationship figure. It is a figure explaining the display switching which the model analysis assistance apparatus which concerns on embodiment performs. It is a flowchart which shows the flow which a control part performs.

  Embodiments according to the present invention will be described below with reference to the accompanying drawings.

(First embodiment)
A first embodiment will be described. The model analysis support apparatus of the first embodiment is for performing optimization and examination of a simulation model based on block diagram information of a block diagram output by Simulink (registered trademark). That is, the software (Simulink (registered trademark)) outputs a block diagram and accompanying block diagram information. Then, the model analysis support apparatus acquires the output information and supports the analysis / examination of the simulation model. The model analysis support program is for realizing a function for that purpose.

1. Block Diagram FIG. 1 shows an example of a block diagram output by Simulink (registered trademark). As shown in FIG. 1, in the block diagram, elements (1010, 1020, 1100, etc.) and connections (L1, L2, L3, etc.) connecting the elements are drawn. Here, there are at least two types of elements: a processing element having a process to be executed and a connecting element having only connection information for connecting the processing elements without having a process to be executed. The connection line L1 is a connection line that connects the processing element 1010 and the processing element 1300.

  Connection L1 is indicated by an arrow. This connection L1 indicates that information (including numerical values, character strings, and other information; the same applies hereinafter) output from the processing element 1010 has been passed to the processing element 1300. Accordingly, processing element 1300 is dependent on processing element 1010. Here, the processing element 1010 is referred to as a dependency source of the processing element 1300, and the processing element 1300 is referred to as a dependency destination of the processing element 1010. That is, the upstream side of the simulation model processing is the dependency source, and the downstream side of the processing is the dependency destination.

  FIG. 1 shows a hierarchy D1, a hierarchy D2, and a hierarchy D3. The hierarchy D2 and the hierarchy D3 are lower than the hierarchy D1. Conversely, the hierarchy D1 is a hierarchy higher than the hierarchy D2 and the hierarchy D3. If all the processing elements are expressed in one plane, it becomes very complicated. Therefore, in Simulink (registered trademark), for convenience, one or more hierarchies can be created. Therefore, data output from Simulink (registered trademark) generally extends to a plurality of layers.

  As described above, the block diagram includes a plurality of processing elements and connection information that represents the dependency between these processing elements. Here, in view of a certain processing element, the direction of the dependence source (the source of the arrow) is assumed to be upstream. The direction of the dependence destination (point of arrow) is assumed to be downstream from the viewpoint of a certain processing element. This concept of upstream and downstream holds even across multiple hierarchies.

  As shown in FIG. 1, the processing elements are processed from the upstream side (left side in the figure) to the downstream side (right side in the figure). However, as indicated by L11, there is an arrow from the downstream side toward the upstream side. Therefore, the processing element 1100 and the processing element 1300 depend on the processing element 1430. As described above, there may be a “return” in which the upstream processing element receives the processing result of the downstream processing element. This return processing must be appropriately managed from the viewpoint of readability and simulation execution test.

  Here, the information outputted from Simulink (registered trademark) is passed the coordinates of each processing element and the information of the connection. In addition, information such as processing and calculation specifically performed by each processing element is also passed. The model analysis support apparatus according to the present embodiment can support optimization of a simulation model and analysis / examination of a processing element by a user using at least a part of the transferred information.

2. Model Analysis Support Device The model analysis support device 1 according to the present embodiment uses a design structure matrix (DSM) that expresses dependency relationship information between a plurality of elements output from Simulink (registered trademark) to analyze and analyze a simulation model. This is to support optimization. FIG. 2 shows the hardware configuration of the model analysis support apparatus 1 of this embodiment. The model analysis support device 1 includes a processing device 10, an input unit 20, and a display unit 30. The processing device 10 specifically performs various processes of the model analysis support device 1. The input unit 20 is for receiving input from the user. Alternatively, an output result from another computer may be accepted. An example is a keyboard. The display unit 30 is for displaying the results of executing various processes by the processing apparatus 10. For example, a display is mentioned.

  The processing device 10 includes a control unit 100 and a nonvolatile memory 200. The control unit 100 performs various controls. The control unit 100 includes a CPU (C1) and a memory M1. The control unit 100 performs various controls by using the CPUC1 and the memory M1. The non-volatile memory 200 stores a program P1. The program P1 is a model analysis support program for causing a computer to realize the model analysis support device 1 as described later.

3. Control Unit FIG. 3 is a block diagram for explaining each unit that performs various controls in the control unit 100. Each unit of the control unit 100 functions by using at least a part of the CPUC1 and at least a part of the memory M1.

  The control unit 100 includes a dependency relationship information acquisition unit 110, a display diagram setting unit 120, a development omitted information holding unit 130, a display control unit 140, an input receiving unit 150, a development omitted information changing unit 160, and other And a control unit 180. The display control unit 140 includes a design structure matrix display unit 141 and a relationship diagram display unit 142. The input receiving unit 150 includes an end instruction receiving unit 151 and a display method receiving unit 152.

  The dependency relationship information acquisition unit 110 has a dependency relationship information acquisition function for acquiring information related to a block diagram output from Simulink (registered trademark). That is, a plurality of elements, dependency relationship information between a dependency source element and a dependency destination element, and a hierarchical structure in which some of the plurality of elements constitute one or more lower layers, get. In addition, the coordinates of the processing elements and the specific processing contents thereof are also acquired.

  The expansion omission information holding unit 130 has an expansion omission information holding function for holding information on whether or not to expand and display each of a plurality of hierarchies. The expansion omission information holding unit 130 holds expansion omission information of a certain lower hierarchy in correspondence with the lower hierarchy. For example, if the expansion omission information of the hierarchy D2 is “1”, it means that the hierarchy is displayed in an expanded state. If the expansion omission information of the hierarchy D2 is “0”, the hierarchy is collapsed and omitted. It means to display in the state. Here, “1” is an expanded value indicating that the image is expanded and displayed. “0” is an abbreviated value indicating that display is omitted. That is, the expansion omission information is either an expansion value or an omission value. Of course, logical variables may be used instead of integer variables. These expanded values are assigned to each hierarchy. Each development value is changed based on designation by the user.

  The display control unit 140 has a display control function for causing the display unit 30 to display processing results processed by the control unit 100. The design structure matrix display unit 141 has a design structure matrix display function for causing the display unit 30 to display a design structure matrix (DSM) based on the expansion omission information held by the expansion omission information holding unit 130. is there. In other words, the design structure matrix display unit 141, when the expansion omission information of a certain lower hierarchy held by the expansion omission information holding unit 130 is an expanded value, the design structure matrix (DSM) expanded from the lower hierarchy ) Is displayed on the display unit 30. On the other hand, when the development omission information of a certain lower layer held by the development omission information holding unit 130 is a default value, the design structure matrix (DSM) in which the lower layer is omitted is displayed on the display unit 30. .

  The relationship diagram display unit 142 has a relationship diagram display unit function for causing the display unit 30 to display a relationship diagram, which will be described later, based on the expansion omission information held by the expansion omission information holding unit 130. That is, when the expansion omission information of a lower hierarchy held by the expansion omission information holding unit 130 is an expanded value, the relationship diagram display unit 142 displays a relationship diagram in which the lower hierarchy is expanded. To display. On the other hand, when the development omission information of a certain lower hierarchy held by the development omission information holding unit 130 is an omission value, a relationship diagram in which the lower hierarchy is omitted is displayed on the display unit 30.

  The input receiving unit 150 has an input receiving function for receiving input from the user. The end instruction receiving unit 151 has an end instruction receiving function for receiving a user's end instruction. The display method accepting unit 152 has a display method accepting function for accepting a user's designation including the presence / absence of development of the diagram displayed on the display unit 30. That is, the display method receiving unit 152 receives the display method of the display diagram to be displayed on the display unit 30 as an unexpanded input value and displays the display diagram to be displayed on the display unit 30 as either the design structure matrix (DSM) or the relationship diagram. Is accepted as a display diagram input value.

  The display diagram setting unit 120 has a display diagram setting function for causing the display unit 30 to display a display diagram by the display method acquired by the display method receiving unit 152. That is, the display diagram setting unit 120 sets which display diagram of the design structure matrix (DSM) or a relation diagram described later is to be displayed on the display unit 30. Specifically, the display diagram setting unit 120 displays the design structure matrix display when the display diagram input value in a certain lower hierarchy that has received input by the display method reception unit 152 corresponds to the design structure matrix (DSM). The unit 141 is configured to display the design structure matrix (DSM) on the display unit 30. On the other hand, when a display diagram input value in a certain lower hierarchy, whose input is received by the display method receiving unit 152, corresponds to the relationship diagram, the relationship diagram display unit 142 is configured to display the relationship diagram on the display unit 30. .

  The expansion abbreviation information changing unit 160 has a development abbreviation information changing function for changing the expansion abbreviation information held by the expansion abbreviation information holding unit 130 based on the expansion abbreviation input value received by the display method receiving unit 152. . That is, the expansion omission information change unit 160 receives an input from the display method reception unit 152, and if the expansion omission input value in a certain lower hierarchy is a value indicating that the input is expanded and displayed, Change the expansion omission information to the expanded value. On the other hand, when the input of the expansion omitted in a certain lower layer received by the display method receiving unit 152 is a value indicating that the display is omitted, the expansion omitted information in the lower layer is changed to the default value. To do.

4). Design structure matrix (DSM)
FIG. 4 is an example of a design structure matrix (DSM) displayed on the display unit 30 by the design structure matrix display unit 141 of the control unit 100 based on block diagram information output from Simulink (registered trademark). is there. FIG. 4 is a design structure matrix (DSM) corresponding to the block diagram of FIG. Here, Subsystem 1 and Subsystem 2 are processing elements having lower layers.

4-1. Arrangement of Elements in the Design Structure Matrix In the design structure matrix (DSM) row (left side in FIG. 4), processing elements are arranged in order. Similarly, the columns of the design structure matrix (DSM) (upper side in FIG. 4) contain processing elements arranged in the same order as the rows. Therefore, the design structure matrix (DSM) is an n × n matrix. As described above, in FIG. 1, the left side is upstream. For this reason, the elements are arranged in order from the upstream element, and are placed in the rows or columns of the design structure matrix (DSM). That is, the order is processing element 1010, processing element 1020, processing element 1100, processing element 1210, processing element 1300, processing element 1410, processing element 1420, and processing element 1430.

4-2. Dependency Relationship Information As shown in FIG. 4, the matrix includes a dependency relationship between the processing elements. Here, there is a dependency relationship between elements containing “1”. There is no dependency between elements containing “0”. In FIG. 4, a blank is displayed instead of “0”. The element Q1 displayed on the left side in FIG. 4 represents the dependence destination, and the element Q2 displayed on the upper side in FIG. 4 represents the dependence source.

  For example, since A1 (processing element 1010) does not depend on any processing element, the row component of the row of A1 (processing element 1010) has a value of “0”. Since Subsystem 1 (processing element 1100) depends on A2 (processing element 1020) and 1 / Z (processing element 1430), “1” is included in these row components. However, “0” is entered in the other row components. As described above, the dependency represented by the connection (arrow) in the block diagram of FIG. 1 is represented by the matrix component.

  Thus, the off-diagonal component of the design structure matrix (DSM) contains either “0” or “1”. When the off-diagonal component between the i-th element and the j-th element in the design structure matrix (DSM) is “1”, the i-th element and the j-th element have a dependency relationship. It is shown that. When the off-diagonal component between the i-th element and the j-th element in the design structure matrix (DSM) is “0”, the i-th element and the j-th element have no dependency. It is shown that. Thus, the off-diagonal component of the design structure matrix (DSM) is dependency information.

  The diagonal element is “0” in principle. However, when there is a hierarchical structure, the sum of the numerical values of the dependencies within the hierarchy is shown. For example, “6” is entered in the diagonal element of Subsystem 1 (processing element 1100).

5. Hierarchical structure and display method 5-1. Hierarchical Structure FIG. 5 is a diagram showing the hierarchy D2. As shown in FIG. 5, the dependency element of the hierarchical element 1120 is a processing element 1020. The dependency destination of the hierarchy element 1120 is the processing element 1150. As described above, the Subsystem 2 indicated by the hierarchy D2 in FIG. 5 has a plurality of dependency relationships that associate the dependency sources and the dependency destinations between the elements. Note that the hierarchical element 1120 has only connection information between the processing element 1020 and the processing element 1150.

  In order to display these hierarchical structures, there are a design structure matrix display and a relationship diagram display. Any of these display methods can be displayed with the hierarchical structure omitted, or the hierarchical structure can be expanded and displayed. Therefore, these will be described next.

5-2. Design Structure Matrix Display Here, the case where the dependency is shown by the design structure matrix (DSM) will be described. As described above, the dependency relationship information has a hierarchical structure. Therefore, the model analysis support apparatus 1 according to the present embodiment displays an “abbreviated display mode” in which all lower layers are displayed by being collapsed, and “expanded” in which at least a part of the lower layers is expanded and displayed. Display mode ".

  FIG. 4 is a diagram illustrating a case where a design structure matrix (DSM) in the abbreviated display mode is displayed. As shown in FIG. 4, in the abbreviated display mode, Subsystem 1 (processing element 1100) and Subsystem 2 (processing element 1300) are folded and displayed in the design structure matrix (DSM) with these detailed structures omitted. ing. In FIG. 4, all lower layers are omitted. Since FIG. 4 is drawn with each hierarchical structure omitted, it is suitable for the user to grasp the entire structure.

  FIG. 6 is a diagram showing a case where the design structure matrix (DSM) in the expanded display mode is displayed. As shown in FIG. 6, these are displayed in a state in which Subsystem 1 (processing element 1100) is expanded and Subsystem 2 (processing element 1300) is folded. In other words, at least a part of the hierarchical structure is displayed in an expanded state. In other words, at least one or more lower layers of the dependency relationship information having one or more lower layers are displayed in an expanded state. For this reason, a case where a part of the processing elements (Subsystem 2 (processing element 1300) in FIG. 6) is omitted is included.

  As shown in FIG. 6, in the expanded display mode, the design structure matrix (DSM) displays not only the dependency information of the uppermost hierarchy D1, but also the dependency information in the lower hierarchy D2. . In the expanded display mode illustrated in FIG. 6, dependency information between elements included in the Subsystem 1 (processing element 1100) is specifically illustrated. For example, Calc1 (processing element 1140) of Subsystem1 (processing element 1100) depends on B1 (connection element 1110) and Const (processing element 1130).

  Further, in the expanded display mode shown in FIG. 6, the dependency relationship information between the elements included in the Subsystem 1 (processing element 1100) and the elements belonging to the hierarchy D1 is also specifically shown. For example, B1 (connection element 1110) is dependent on 1 / Z (processing element 1430). Thus, in the expanded display mode, the user can study the simulation model in consideration of the detailed hierarchical structure of the lower hierarchy.

  In this way, when displayed in a folded and omitted state, it is displayed as a cell in the design structure matrix (DSM) (see FIG. 4). When displayed in an expanded state, it is displayed as a matrix inside the design structure matrix (DSM) (see FIG. 6).

  In FIG. 6, these are displayed in a state where the Subsystem 1 (processing element 1100) is expanded and the Subsystem 2 (processing element 1300) is folded. However, Subsystem 2 (Processing Element 1300) can be expanded and displayed in addition to Subsystem 1 (Processing Element 1100). As described above, the expanded display mode includes not only a case where a part of a plurality of hierarchies is expanded and displayed but also a case where all are expanded and displayed.

  Actually, the user can examine the detailed hierarchy while grasping the overall image of the simulation model by appropriately expanding and displaying the hierarchy located at the lower level from what is omitted and displayed. .

5-3. Relationship Diagram Display FIG. 7 is a relationship diagram showing dependency relationship information in a state where lower layers are omitted. The relationship diagram of FIG. 7 corresponds to the design structure matrix (DSM) of FIG. In FIG. 4, the dependency relationship information is indicated by matrix elements, whereas in FIG. 7, the dependency relationship information is indicated by arrows. Specifically, the rear end (root) of the arrow indicates the dependency source, and the tip of the arrow indicates the dependency destination. This corresponds to the processing order when the simulation is actually performed. Therefore, there is no further difference between FIG. 4 and FIG. In FIG. 7, as in FIG. 4, all lower layers are omitted. Therefore, FIG. 7 is suitable for the user to grasp the entire structure, as in FIG. FIG. 7 is suitable for grasping the flow of processing between the processing elements as compared with FIG. 4 because the dependency relationship is indicated by an arrow.

  FIG. 8 is a relationship diagram showing the dependency relationship information in a state where at least a part of the lower hierarchy is expanded. The relationship diagram of FIG. 8 corresponds to the design structure matrix (DSM) of FIG. In FIG. 6, the dependency relationship information is indicated by matrix elements of the matrix, whereas in FIG. 8, the dependency relationship information is indicated by arrows. Therefore, there is no further difference between FIG. 6 and FIG. In FIG. 8, as in FIG. 6, a part of the lower hierarchy (Subsystem 1 (processing element 1100)) is expanded and the remaining part (Subsystem 2 (processing element 1300)) is omitted and displayed.

  Therefore, the user can examine the simulation model while grasping the detailed dependency relationship for the developed part. 8 is suitable for grasping the flow of processing between the processing elements as compared with FIG. 6 because the dependency relationship is indicated by an arrow as in FIG.

6). Switching the display method of the hierarchical structure As described above, it is preferable that the user examines the simulation model while switching each of the above display methods. Therefore, the model analysis support apparatus 1 according to the present embodiment includes an omitted design structure matrix (DSM) display (see FIG. 4), an expanded design structure matrix (DSM) display (see FIG. 6), and an omitted relationship diagram display. (See FIG. 7) and the expanded relationship diagram display (see FIG. 8) can be switched and displayed. And these switching can be performed by receiving the input by a user.

6-1. Switching method These switching methods will be described. First, for simplicity, the case where there is one lower hierarchy will be described with reference to FIG. When an omitted design structure matrix (DSM) is displayed and an instruction for a hierarchy to be expanded is received by the user, as shown by an arrow AR1 in FIG. DSM) is displayed. When the expanded design structure matrix (DSM) is displayed and the user accepts an instruction to omit the hierarchy, as shown by the arrow AR2 in FIG. 9, the supported hierarchy is omitted and the design structure matrix ( DSM) is displayed.

  Each display can be switched by performing the same processing. That is, as shown by an arrow AR3 in FIG. 9, it is possible to switch to a relationship diagram in which the omitted design structure matrix (DSM) is omitted. As shown by an arrow AR4 in FIG. 9, the omitted relationship diagram can be switched to a design structure matrix (DSM). As shown by an arrow AR5 in FIG. 9, the omitted relationship diagram can be switched to a developed relationship diagram. As shown by an arrow AR6 in FIG. 9, the developed relationship diagram can be switched to a relationship diagram omitted. As shown by the arrow AR7 in FIG. 9, the expanded design structure matrix (DSM) can be switched to the expanded relationship diagram. As shown by an arrow AR8 in FIG. 9, the expanded relationship diagram can be switched to the expanded design structure matrix (DSM).

  In the above description, the case where one lower hierarchy is expanded has been described. However, a design structure matrix (DSM) or a relationship diagram in which one lower layer is expanded can be displayed by further expanding another lower layer.

6-2. Method for Accepting Input by User Here, a method for accepting input by the user will be described. When the user designates the areas K1 and K2 in FIG. 4, the Subsystem 1 is expanded and FIG. 6 is displayed on the display unit 30. When the user designates the area K3 in FIG. 4, the relationship diagram in FIG. 7 is displayed on the display unit 30. That is, the areas K1 and K2 in FIG. 4 are areas for displaying the developed design structure matrix (DSM) on the display unit 30. A region K3 in FIG. 4 is a region for displaying the relationship diagram omitted in FIG.

  Similarly, areas K4 and K5 in FIG. 6 are areas for accepting the cancellation of expansion. A region K6 in FIG. 6 is a region for displaying the developed relation diagram in FIG. A region K7 in FIG. 7 is a region for expanding the Subsystem 1 and displaying FIG. 8 on the display unit 30. A region K8 in FIG. 7 is a region for displaying the design structure matrix (DSM) omitted in FIG. A region K9 in FIG. 8 is a region for omitting the Subsystem 1 and displaying FIG. 7 on the display unit 30. A region K10 in FIG. 8 is a region for displaying the developed design structure matrix (DSM) in FIG. The designation of these areas may be made when the user designates and clicks with the mouse. Also, the area may be designated by inputting from the keyboard. Of course, other methods than the designation of the area may be used.

7). Control Flow A control flow executed by the model analysis support apparatus 1 of this embodiment will be described with reference to the flowchart of FIG. First, model information is acquired (S101). Here, the element, the connection (dependency relationship information), the hierarchy, and the coordinates of the element are acquired. Of course, other information may be acquired. Next, element rearrangement is executed (S102). Specifically, the control unit 100 executes. The processing content is as described in the rearrangement of the design structure matrix.

  Next, the omitted design structure matrix (DSM) is displayed (S103). Next, an input by the user is accepted (S104). Here, an input for specifying a display method to be switched is accepted. When the user desires to end the display, an input to that effect is accepted.

  If the received input by the user is an instruction to end the display (S105: Yes), the display ends. When that is not right (S105: No), it progresses to S106. In S106, according to the received instruction, the display method is switched by the method shown in FIG. Then, the process proceeds to S104.

  By switching the display method described above, the user examines the model process. If necessary, the order of the elements is changed.

8). Modification 8-1. Storage Medium In the present embodiment, the model analysis support apparatus 1 and the model analysis support program P1 have been described. However, the present invention can of course be applied to a storage medium in which the model analysis support program P1 is recorded. This storage medium is a computer-readable storage medium that stores the model analysis support program P1. Examples of the storage medium include CDROM and DVDROM. Of course, it may be other than this.

8-2. Weighting of Dependency of Design Structure Matrix In this embodiment, a value of “1” is set as a matrix element having a dependency. However, if the dependency is strong, a larger numerical value may be entered. In other words, the larger the dependency, the larger the value.

8-2-1. The weight may be changed between the connection element and the processing element or between the connection element and the processing element. For example, the dependency between the processing elements is “3”. The dependency between the processing element and the connection element is “2”. The dependency between the connection elements is “1”. Since the connection element does not have a process to be executed, the dependency relationship related to the connection element is estimated to be small. The matrix component of the weighted design structure matrix (DSM) is referred to as a dependency value.

  The control unit 100 includes a dependency relationship update unit 170 (see FIG. 3) for executing this process. The dependency relationship update unit 170 has a dependency relationship update function. That is, the dependency relationship update unit 170 changes the dependency value between the connection elements and the processing elements as a value larger than the dependency value between the connection elements. Then, the dependency relationship value between the processing elements is changed to a value larger than the dependency relationship value between the connection element and the processing element. These processes may be performed together with the execution of S102 in the flow of FIG. 10 or before and after S102.

8-2-2. Change of arrow characteristics (line type, thickness, color) And, when displaying the relationship diagram, depending on the dependency value indicating the above dependency, change the thickness of the arrow connecting each element Good. That is, the larger the dependency value displayed in the design structure matrix (DSM), the thicker the arrow indicating the dependency. For example, in the above example, the arrow connecting the processing elements is the thickest, the arrow connecting the processing elements and the connection elements is the next thickest, and the arrow connecting the connection elements is the thinnest. Or it is good also as showing the arrow which the connection element relates with a broken line. Or it is good also as changing the color of the arrow to display according to the numerical value which shows dependence. In these cases, the relationship diagram display unit 142 performs these processes. By the above method, the efficiency of the user's examination of the simulation model is improved.

8-3. Replacement of Elements in Design Structure Matrix (DSM) In the control flow (FIG. 10) described above, the arrangement of elements in the design structure matrix (DSM) is determined based on the arrangement of the block diagram. However, the elements may be replaced by a known method (for example, see Patent Document 1).

8-4. Display Method Switching Input Method In this embodiment, the display method is switched according to FIG. However, a list of hierarchies may be shown to the user, and an input for designating a hierarchy to be expanded may be accepted. Thus, it is good also as receiving a user's input.

8-5. Use of Drawing Software Existing software can be used to display the relationship diagram in the abbreviated display mode and the expanded display mode of the present embodiment. An example is Graphviz. Of course, other software may be used.

8-6. Acquisition of Dependency Information In this embodiment, the dependency information output by Simulink (registered trademark) is acquired. However, it is not necessarily limited to this. That is, as long as it has a dependency relationship between the dependency source and the dependency destination, other dependency relationship information can be similarly applied.

8-7. In general, a lower hierarchy may exist in the lower hierarchy D2. Even in such a case, the hierarchy can be expanded or omitted by appropriately selecting a lower hierarchy.

9. Summary of the present embodiment As described in detail above, the model analysis support apparatus 1 and the model analysis support program P1 of the present embodiment can optimize a simulation model using a design structure matrix (DSM). . In addition, with respect to the dependency relationship information having one or more hierarchies, a display diagram omitted and an expanded display diagram can be appropriately displayed on the display unit 30. Therefore, the user can reconstruct the simulation model according to the user's design philosophy by considering these in a composite manner.

  In addition, a present Example is only a mere illustration. Therefore, naturally, various improvements and modifications can be made without departing from the scope of the invention.

(Second Embodiment)
A second embodiment will be described. In the first embodiment, the processing element of the simulation model is used. However, the development process may be a processing element. For example, development of automobile engines and the like can be mentioned. In that case, the processing elements of FIG. 1 and FIG. 4 are development steps. By using the design structure matrix (DSM), it is possible to shorten the engine development period by optimizing the engine development process.
