Abstract

PURPOSE:To allow an unskilled operator to facilitate the analysis of the correlation between events and the division of the events by automatically rearranging a matrix so as to be visible when the elements of the event related matrix to express the relation between the events are dispersed. CONSTITUTION:An analyzing device 7 rearranges the elements by a two event relation analyzing system to arrange and analyze the event related matrix stored into an information memory 6 so as to be correlated between the elements of the two events expressed in a matrix form, and its result is delivered to a display device 1 together with the division candidate of the event, and only the result is stored into the information memory 6 again. A controller 8 consists of a mode switching processing part 9 to switch a single mode, which indicates the relation of the elements of the events by the presence and absence of the relation, and a multi-stage mode, which indicates a relation degree by stages, and a data mask processing part 10 to execute masking by the multi- stage mode in the special stage. Thus, even the unskilled operator can easily set and cancel the editing and relation of the element name of the respective event.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a two-event relationship analysis device, and in particular, an event system that expresses the presence or absence of a relationship when focusing on the relationship between two events such as an abnormal symptom and a cause in a plant or the like. This invention relates to a two-event relationship analysis device that creates a relationship matrix and edits, saves, and analyzes the data.

[Conventional technology]

Conventionally, when analyzing the relationship between two events, such as an abnormal symptom and a cause in a plant, an event-related matrix has been described that expresses the existence and degree of the relationship between the elements of each event. However, this matrix was written by humans, and there was no way to save, edit, or analyze the data on a device.

[Problem to be solved by the invention]

In this type of conventional technology, the event-related matrix is written on paper, so if element data of an event is added, deleted, or moved in the event-related matrix once defined, the matrix is rewritten each time. I had to.

Also, the described matrix is difficult to see when the relationships between elements are dispersed, and it is difficult to tell at a glance which element A of event 1 is related to or is not related to which element of event 2. Ta.

Furthermore, if the matrix is large, it may be possible to group the elements of the event, divide it into sub-events, and analyze the relationships between them, but the information for the division can be obtained from the described matrix. That was difficult.

The drawbacks of the conventional technology are as mentioned above. Therefore, an object of the present invention is to provide a two-event relationship analysis device that solves these drawbacks.

[Means to solve the problem]

The two-event relationship analysis device of the present invention includes an information input editing device that inputs and edits element data constituting an event and related information between the element data of two events in a matrix, and an information input editing device that inputs and edits the data input by the information input editing device. An information storage device that stores and stores information, an analysis device that analyzes an input matrix and rearranges the elements of the matrix, a display device that displays the related information in matrix format, and at least a mode switching and data display device. It consists of a control device that performs masking, and is configured to edit, analyze, and display relationships between element data input by the information input and editing device in two events.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In FIG. 1, reference numeral 1 indicates a display device for displaying an event-related matrix. In the information input/editing device 2, the information input/edit processing section 4 accepts and edits the element name and related information of the event in the event-related matrix, passes the element name and related information to the display device 1, and then performs data writing processing. The data is stored in the information storage device 6 by the data storage unit 5, or retrieved from the information storage device 6 by the data read processing unit 3.

The analysis device 7 rearranges the elements of the event-related matrix stored in the information storage device 6 using a two-event-related analysis method that organizes and analyzes the elements of two events expressed in a matrix format in relation to each other. The result is passed to the display device 1 along with the event division candidates, and only the result is stored again in the information storage device 6. The control device 8 also includes a mode switching processing unit that performs switching between a single mode that indicates the relationship between the elements of an event as whether there is a relationship, and a multi-step mode that shows the degree of the relationship in stages, and Mask at each stage (treat as irrelevant)
It is composed of a data mask processing section 10.

FIG. 2 is a chart showing an example of inputting an event-related matrix in the single mode, and shows an example of information stored in the information storage device 6. This figure is expressed in a single mode, with only the presence or absence of a relationship, with the vertical axis representing an event and the horizontal axis representing an event 2. The information input/edit processing unit 4 can edit the element name of each event and set/cancel relationships.

FIG. 3 shows the results of analysis of the data shown in FIG. 2 by the analyzer 7. From this matrix, element 16.2 of event 2
3, 12, and 30 have no relation to event 1, or that element 16 of event 1 is only related to element 3 of event 2, which can be easily determined by just looking at the matrix. Recognize. Also, the vertical and horizontal lines in the figure are the analysis device 7.
This is an example of dividing events 1 and 2 from the division candidates listed by , and it can be seen that events 1 and 2 can be divided neatly except for the relationship between element 2 of event 1 and element 8 of event 2. . Here, when considering group 1 of event 1, it is not necessary to target group 2 of event 2.

FIG. 4 shows an example in which data is set in multi-stage mode, and in this example, data is set and displayed in three stages: triangle, double circle, and double circle.

FIG. 5 is an example in which triangular data is masked from the example in FIG. 4. This allows analysis to exclude cases where the relationship is weak. In the analysis device 7, when in the multi-stage mode, by considering the weighting of relationships, it is also possible to rearrange elements with strong relationships so that they are closer to the center of the diagonal.

〔Effect of the invention〕

As explained above, the present invention combines and considers the elements of events and matters to be focused on in a problem, and enables the analysis of the relationships between events in the work of analyzing the relationships or dividing and organizing the events. When the elements of an event-related matrix expressing events are scattered, it is possible to provide a system that automatically rearranges the matrix to make it easier to read, so even inexperienced workers can analyze the relationships between events and divide the events. The effect is that it can be done easily.

Figure 3 is a diagram showing the results of analyzing this data with an analysis device, Figure 4 is a diagram showing input examples in multi-stage mode, and Figure 5 is a diagram showing data mask processing for this data. Chart when data with weak relationships are masked.
