Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing a configuration of a time-series analysis support system according to an embodiment of the present invention. The time series analysis support system of this embodiment is realized by the CPU 11 executing the time series support program stored in the storage unit 12 on the computer having the configuration shown in FIG.

  In FIG. 1, a CPU 11 in the computer 1 is a CPU (Central Processing Unit) that controls each unit in the computer 1 and executes various programs stored in the storage unit 12. The storage unit 12 is a hard disk that stores programs executed by the CPU 11. The operation unit 13 is used to input an operation by an analyst, and is, for example, a pointing device such as a keyboard or a mouse. The display unit 14 is a display that displays information to be shown to the analyst based on an instruction from the CPU 11.

  In addition to the time-series support program executed by the CPU 11, the storage unit 12 stores event classifications and support information to be displayed corresponding to the classifications (event support information storage unit). The storage unit 12 stores an error type and support information to be displayed corresponding to the error type (analysis support information storage unit). Furthermore, the memory | storage part 12 memorize | stores the support information displayed corresponding to a keyword and this keyword (character string support information storage means). Details of these will be described later.

  Next, details of processing when the CPU 11 executes the time-series support program stored in the storage unit 12 will be described. FIG. 2 is a flowchart showing a processing procedure of the CPU 11 in the time series support program.

  In FIG. 2, when the time series support program is executed, the CPU 11 first reads the time series analysis sheet from the storage unit 12 and creates an event flow (step S201). Subsequently, an operation by the analyst is input from the operation unit 13 to create a factor flow (step S202). Finally, an operation by the analyst is input from the operation unit 13 to create a countermeasure flow (step S203).

Hereinafter, detailed processing of steps S201 to S203 will be described with reference to FIGS.
FIG. 3 is a flowchart showing the process in step S201 of FIG. In FIG. 3, when the creation of the event flow is started, the CPU 11 reads the time series analysis sheet (step S301, time series information input means).

  The time series analysis sheet is, for example, a document in which the contents shown in FIG. 6 are written, and is stored in the storage unit 12 in FIG. The time series analysis sheet may be created by the computer 1, or a document created by an external computer or the like may be recorded on a medium and read by the CPU 11.

  In FIG. 6, the time series analysis sheet describes information indicating the general condition of the event such as the classification of the event, the item in which the event has occurred, and the parties concerned, and the time series information indicating the process leading to the event in time series. . In time-series information, items that require analysis are bolded and underlined in formatting.

  Furthermore, each underlined factor is classified into human errors that violate standard procedures, etc., and judgments / actions where standard procedures and handling are not stipulated, but lacked consideration. Is described as “<error>” in the time series analysis sheet, and “<insufficient consideration>” is described in the time series analysis sheet for the latter.

  The CPU 11 reads the time series analysis sheet, and searches for and imports information related to the general situation of the event and a portion underlined in the format of the time series information. The CPU 11 causes the display unit 14 to display time series information taken from the time series analysis sheet.

  In order to display not only human errors but also lack of consideration on the display unit 14 and facilitate analysis by the analyst, the cause of the event can be viewed from various viewpoints from various viewpoints by using the time series support program of this embodiment. Can be analyzed.

  In addition, the CPU 11 recognizes a specific format (underline) of the time series analysis sheet and extracts time series information to be analyzed, thereby automatically extracting time series information from a previously created document. It becomes possible.

  FIG. 7 is an example of a screen displayed on the display unit 14, and time-series information is displayed in time-series order in the “event flow” field 41. When there are a plurality of parties related to the event, the time series information captured from the time series analysis sheet may be rearranged in the time series for each party.

  Returning to FIG. 3, when the reading of the time series analysis sheet is completed, the CPU 11 selects a classification of the event based on the information read from the time series analysis sheet (step S302, event type selection means). For example, in the time series analysis sheet of FIG. 6, the event type is “signal advance”, and by taking in this time series analysis sheet, the CPU 11 selects “signal advance” as the event classification. The selection of the event classification in step S302 may be performed by the CPU 11 displaying the classification as an option on the display unit 14 and taking in the selection input by the analyst.

  When the selection of the event classification is completed, the CPU 11 reads out information regarding factors or countermeasures specific to the selected event classification from the storage unit 12 and displays the information on the display unit 14 (step S303, event support information display means). In the example of the screen shown in FIG. 7, a guide for each event is displayed in the frame of reference numeral 44.

  In this way, by displaying the factors and countermeasures specific to the classification according to the classification of the event as event support information, the analyst can analyze the cause and countermeasure of the event by referring to the support information. Analysts can easily perform accurate analysis.

  Subsequently, the CPU 11 displays a screen for selecting an error type for each time series information (<error> and <under consideration>) read from the time series analysis sheet (step S304, time series information type selection means). . In the time series support program of the present embodiment, as means for selecting an error type, means for displaying and selecting the error type shown in FIG. 8 directly as options, and a question format option being displayed multiple times by the analyst. There are two types: a means for inputting an answer and a means for determining an error type based on the input of the answer.

  When the selection of the error type is completed, the CPU 11 causes the display unit 14 to display information to be considered for each selected error type (step S305, analysis support information display unit). In the example of the screen shown in FIG. 7, information is displayed within a frame denoted by reference numeral 45.

  Specifically, for example, when “interrupt type forgetting” in FIG. 8 is selected as the error type, from the viewpoint of 4M “person”, “whether the person is sufficiently aware of the fear of interruption? ”Or“ Is it sufficient to follow or follow up with other members? ”, And from the perspective of 4M“ things / environment ”,“ has an opportunity to remember the work? ”And 4M From the viewpoint of “management”, “is it a work form in which interruption frequently occurs during important work?” Is displayed.

  In this way, the CPU 11 causes the display unit 14 to display information that should be considered in the analysis of factors and countermeasures when an error occurs for each error type, so that the analyst can analyze the factors classified into the error types. Can be carried out effectively. Further, by displaying the question format choices, the analyst can select an accurate error type for each time series information from the error types shown in FIG. 8 without requiring specialized knowledge. .

  The creation of the event flow is completed as described above, and the cause flow creation process in step S202 of FIG. 2 will be described with reference to the flowchart of FIG. In the flowchart of FIG. 4, the essential factor that is the fundamental factor is analyzed for each time-series information fetched from the time-series analysis sheet in step S201.

  In FIG. 4, when the creation of factors is started for each time series information (step S401), the CPU 11 first has four viewpoints (4M): human (Man), thing (Machine), environment (Media), and management (Management). ) As an option on the display unit 14 (step S402, factor viewpoint selection means). FIG. 9 is an example of a screen displayed as a 4M option. Here, depending on factors, there may be a close relationship with two viewpoints (person and environment, person and management, etc.), and in this embodiment, it is possible to select from 4M to two.

  When the analyst selects one or two from 4M, the CPU 11 inputs the selection instruction, provides a factor input box in the field of reference numeral 42 in the display screen of FIG. 7, and selects the viewpoint selected in the frame. indicate. Specifically, in the screen shown in FIG. 7, when the analyst creates a factor for the time series arrangement information of <error 1>, when “person” is selected as the factor viewpoint, the CPU 11 Create a frame for factor 1-1 and display <person> in the frame. Thereafter, the <error 1> frame in the event column 41 and the factor 1-1 frame in the factor column 42 are connected by an arrow.

  In this way, by providing means to select from the four viewpoints of people, things, environment, and management when creating factors, the analyst is always encouraged to analyze from the four viewpoints. It becomes easy to find out the factors.

  Subsequently, when the CPU 11 captures the factor input by the analyst, the CPU 11 displays it in the input frame provided in step S402 (step S403, factor input means). At this time, the CPU 11 monitors the input by the analyst, and determines whether or not there is a character string that matches the specific keyword in the input character string (step S404, character string search means).

  When a character string matching the specific keyword is searched (step S404: Yes), the CPU 11 reads support information corresponding to the keyword from the storage unit 12 and displays it on the display unit 14 (step S405, character string support). Information display means). In the screen shown in FIG. 7, support information is displayed within a frame 46.

  Here, the specific keyword is stored in advance in the storage unit 12 as a character string that is frequently used during factor analysis and countermeasure formulation. As described above, the CPU 11 displays the support information corresponding to the specific keyword, so that the analyst can perform more effective analysis by referring to the support information when inputting the factor or the countermeasure.

  When the creation of one factor is completed, the analyst examines the factor that causes the factor, and creates a new factor by repeating the processing in steps S401 to S405. When the factor is repeatedly input by the analyst, the CPU 11 creates the factor on the tree as shown in FIG. When the fundamental essential factor is extracted, the factor creation ends (step S406: Yes). Finally, the CPU 11 inputs an operation by the analyst, and sets how much each essential factor affects the event (step S407, influence setting means). By enabling the setting of the degree of influence, the analyst is encouraged to determine which factors should be formulated with priority. Analysts can focus on formulating countermeasures for factors that have a high degree of influence, making it easier to formulate essential countermeasures.

  The arrangement of the factor input frames created in this way on the screen is automatically determined by the CPU 11 when the factor is created. However, the arrangement can be freely changed after the factor is created (display position changing means). The arrangement is changed by, for example, selecting an input frame of a factor with a pointing device provided in the operation unit 13 and moving it by dragging. In this embodiment, it is possible to freely change the factor input frame. Therefore, even in the analysis of events in which factors are intertwined in a complicated manner, the analyst can change the layout so that the arrangement is easy to see. Becomes easier.

  The creation of the factor flow is completed as described above, and the countermeasure flow creation process in step S203 of FIG. 2 will be described with reference to the flowchart of FIG. In the flowchart of FIG. 5, countermeasures are formulated for each essential factor extracted in step S202.

  In FIG. 5, when the creation of countermeasures for each essential factor is started (step S501), the CPU 11 first has four viewpoints (4E) of people (Education), things (Engineering), environment (Environment), and management (Enforcement). Is displayed as an option on the display unit 14 (step S502, countermeasure viewpoint selection means). FIG. 10 is an example of a screen displayed as a 4E option. Here, depending on the countermeasure, there may be a close relationship with two viewpoints (person and environment, person and management, etc.), and in this embodiment, it is possible to select from 4E to two.

  When the analyst selects one or two from 4E, the CPU 11 inputs the selection instruction, provides a factor input frame in the column of reference numeral 43 in the display screen of FIG. 7, and selects the viewpoint selected in the frame. indicate. Specifically, in the screen shown in FIG. 7, when the analyst creates a countermeasure for the essential factor of the factor 1-2, when “person” is selected as the viewpoint of the countermeasure, the CPU 11 measures the countermeasure 1- Create one frame and display <person> in the frame. Then, the frame of the factor 1-2 in the factor column 42 and the frame of the measure 1-1 in the measure column 43 are connected by an arrow.

  In this way, by providing means to select from the four viewpoints of people, things, environment, and management when creating countermeasures, the analyst is always encouraged to analyze from the four viewpoints. It becomes easy to find a suitable measure.

  Subsequently, when the CPU 11 captures the countermeasure input by the analyst, the CPU 11 displays it in the input frame provided in step S502 (step S503, countermeasure input means). At this time, the CPU 11 monitors the input by the analyst, and determines whether there is a character string that matches the specific keyword in the input character string (step S504, character string search means).

  When a character string that matches a specific keyword is found (step S504: Yes), the CPU 11 reads support information corresponding to the keyword from the storage unit 12 and displays it on the display unit 14 (step S505, character string support). Information display means). In the screen shown in FIG. 7, support information is displayed within a frame 46.

  When the creation of one countermeasure is completed, more specific countermeasures are examined for the countermeasure, and the processing of steps S501 to S505 is repeated. When a measure to be specifically executed is determined, the measure creation is terminated (step S506: Yes). Finally, the CPU 11 inputs an operation by the analyst, and sets a priority order for each countermeasure (step S507, priority order setting means). By making it possible to set priorities, analysts are encouraged to determine which measures should be preferentially implemented from among the formulated measures. By setting priorities, the analyst can select the most effective measure to achieve the maximum effect with the minimum cost and burden on the limited resources.

  The arrangement of the countermeasure input frame created in this way is automatically determined by the CPU 11 when it is created, but the arrangement can be freely changed after the countermeasure is created (display position changing means). The arrangement is changed by, for example, selecting a countermeasure input frame with a pointing device provided in the operation unit 13 and moving it by dragging. In this embodiment, it is possible to freely change the input frame of measures, so even in the formulation of measures for events that involve complicated measures, the analyst can change the placement so that it is easy to see. Easy to formulate.

  By using the time series analysis support program of the present embodiment, it is possible to display specialized information as support information at the three locations 44 to 46 in FIG. It is possible to analyze factors from multiple viewpoints for time-series events and formulate countermeasures from multiple viewpoints.

  As mentioned above, although embodiment of this invention was explained in full detail, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
