Description

Embodiments of the present invention relate to screen adaptation devices, screen adaptation methods and programs.

In various business systems such as electric power supply and demand management systems, the operator performs business by inputting / outputting and confirming information while switching between multiple screens. In general, screen transitions when performing business are considered and designed in the early stages of development. Therefore, at the time of system release, it is considered that unnecessary screen transitions are not included. However, in actual operation after the system is released, use cases that the designer did not anticipate may occur due to external factors such as system changes and operator proficiency. In such an unexpected use case, the screen transition may become redundant. Redundant screen transitions can increase operator stress, which in turn can increase the probability of human error.

Hereinafter, the screen adaptation device, the screen adaptation method, and the program of the embodiment will be described with reference to the drawings. The screen adaptation device detects redundant parts of the screen transition by applying machine learning to the log data of the screen transition performed by the user's operation. Screen transitions can be represented using graph theory. Using graph theory, each vertex corresponds to a screen and the path between the vertices corresponds to a screen transition. Redundancy points are represented by a set of paths. The screen adapting device searches for a graph of redundant parts by a predetermined algorithm. As a result of this search, the screen adapting device obtains a list of data to be input / output on the screen of the redundant portion. The screen adapting device determines a change to the current screen transition such that the data in the obtained redundant part is aggregated on a specific screen or a transition is added to reduce the transition of the redundant part. .. With this change, unnecessary screen transitions can be reduced. Therefore, it is possible to identify and improve the redundant part of the screen transition in consideration of the use case after the release.

The information processing device 3 and the screen transition individualizing device 5 are connected via the network 7. The information processing device 3 is, for example, a terminal used for the business of the information system Σ. Although FIG. 2 shows one information processing device 3, the number of information processing devices 3 is arbitrary.

The information processing device 3 includes a communication unit 31, an input unit 32, a display unit 33, a storage unit 34, and a processing unit 35. The communication unit 31 transmits / receives data to / from another device via the network 7. The input unit 32 is an interface for inputting by the user's operation. The display unit 33 is a display for displaying an image. The storage unit 34 stores various types of information including display screen information and operation history information. The processing unit 35 displays the screen on the display unit 33 based on the display screen information stored in the storage unit 34 in advance. The processing unit 35 executes processing related to the business of the information system Σ by using the data value input by the user on the screen by the input unit 32. The processing unit 35 stores the operation history information indicating the history of the operations performed by the user for inputting the data value in the storage unit 34.

For example, the information system Σ is a system in the power system, and the information processing device 3 is a management and operation terminal of the system. The information processing device 3 has a function of forecasting power demand using the values of a plurality of data items. The display screen information indicates a screen identifier of each screen and screen data. The screen identifier is information that uniquely identifies the screen. The screen data is data for displaying a screen for inputting values of data items used for demand forecasting. The screen also includes one or more buttons for selecting the screen of the transition destination to be displayed next. A link to the transition destination screen is embedded in the button. Alternatively, the display screen information may include information on transitions between screens. The screen may also include the display of preset data item values or data item values entered by the user on other screens. A data item for inputting a value on the screen is also described as an input data item, and a data item for displaying a value on the screen is also described as an output data item. The display screen information is provided from the system development environment.

The user uses the input unit 32 to input the value of the input data item and the screen selection of the transition destination on the screen displayed on the display unit 33 by the processing unit 35, or without inputting the value of the input data item. , Enter the screen selection of the transition destination. When the value of the input data item is input, the processing unit 35 stores the value in the storage unit 34. The processing unit 35 displays the next screen according to the input screen selection on the display unit 33. On the other hand, the processing unit 35 writes the operation history information in the storage unit 34. The operation history information includes the user's input history information for the input data item and the screen transition history information by the user's operation. For example, the operation history information includes a screen identifier of a screen displayed by the processing unit 35 based on the user's operation, an input data item for which the user has entered a value on the displayed screen, and a screen based on the user's operation.

The screen transition individualizing device 5 includes a communication unit 51, a storage unit 52, an information acquisition unit 53, a detection unit 54 (update unit), an analysis unit 55 (update unit), and an update unit 56. The communication unit 51 transmits / receives data to / from another device via the network 7. The storage unit 52 stores screen configuration information. The screen configuration information is information indicating a screen identifier that identifies each of the plurality of screens, an input data item of each screen, and an output data item of each screen. In this embodiment, the screen transition diagram acquired from the development environment of the information system Σ is used as the screen configuration information. The screen transition diagram is information including a screen identifier of each screen, an input data item of each screen, an output data item of each screen, and possible transitions between screens.

The information acquisition unit 53 acquires the screen configuration information and the operation history information when the screen of the screen configuration information is used from the storage unit 52. The information acquisition unit 53 may acquire the display screen information from the information processing device 3 and use it as the screen configuration information, or may generate the screen configuration information using the display screen information acquired from the information processing device 3. Good.

The detection unit 54 identifies the wandering operation based on the screen operation history information acquired by the information acquisition unit 53, and detects the wandering start screen, the wandering end screen, and the wandering purpose screen. In order to refer to the data value required to input the value of the input data item on one screen s, the user may perform an operation to display another screen s'. The wandering operation is an operation of moving from this screen s to the screen s'and returning to the screen s again. That is, the wandering operation is an operation of instructing a transition until the same screen s is displayed again after displaying one or more other screens without inputting the value of the input data item. The screen s displayed first is the wandering start screen, and the screen s displayed again is the wandering end screen. The screen transition (specific transition path) from the wandering start screen to the wandering end screen is described as wandering. The wandering start screen is a screen on which the wandering start operation is performed. The wandering end screen is the wandering end screen, that is, the screen displayed by the last operation of the wandering operation. The screen s'is a screen for the purpose of wandering, which is presumed that the output data item is referred to in order to input a value to the input data item in the wandering end screen. In the following, the screen for the purpose of wandering is also described as the screen for the purpose of wandering. The screen for the purpose of wandering s'can be specified from the screens displayed in the wandering operation on the condition that the screens before and after the transition are the same other screens. Screen transition operations other than the wandering operation are defined as normal operations. The operation for ending the wandering performed on the wandering end screen is a normal operation.

The analysis unit 55 calculates the screen visit frequency, the screen visit probability, the transition occurrence frequency, the transition occurrence probability, the data reference frequency, and the data reference probability based on the screen configuration information and the screen operation history information. The screen visit frequency is the number of times each screen is displayed. The screen visit probability is the probability that each screen is displayed. The transition occurrence frequency is the number of times each screen transition has occurred. The transition occurrence probability is the probability that each screen transition has occurred. The data reference frequency is the number of times that another data item becomes a reference data item when the value of the input data item is input. The data reference probability is the probability that another data item becomes a reference data item when the value of the input data item is input. In the case of an input data item on a screen other than the wandering end screen, the output data item on the screen on which the value of the input data item is input is the reference data item. In the case of the input data item of the wandering end screen, the output data item of the wandering end screen and the output data item of the wandering purpose screen are the reference data items. The analysis unit 55 calculates the data reference frequency and the data reference probability for each combination of the input data item and the reference data item.

The update unit 56 determines the transition between screens and at least a part of the update of the input data item or the output data item of each screen based on the extracted wandering (specific transition path). The update unit 56 changes the screen transition diagram according to this determination. Specifically, the update unit 56 specifies a combination of an input data item and a reference data item with a data reference probability that satisfies a predetermined condition indicating high frequency. When the screen for inputting the value of the specified input data item and the screen for including the specified reference data item in the output data item are different, the update unit 56 displays the reference data item from the screen for inputting the value of the input data item. Change the screen transition diagram to reduce the number of operations to refer to. For example, when the specified reference data item is included in the output data item of the wandering purpose screen, the update unit 56 adds the output data item of the wandering purpose screen to the output data item of the screen for inputting the value of the specified input data item. To add. The update unit 56 may integrate the screen for inputting the value of the specified input data item and the wandering purpose screen. Alternatively, the update unit 56 may add a transition between the screen for inputting the value of the specified input data item and the wandering purpose screen. Further, when the update unit 56 determines that the reference data items of the plurality of input data items whose values are input on one screen are different based on the data reference probability, the screen is displayed on each of the plurality of input data items. Separate to the screen for entering values. Further, the update unit 56 detects a screen that has not been displayed based on the screen operation history information, and deletes the detected screen and the transition to the screen from the screen transition diagram.

The information processing device 3 and the screen transition individualizing device 5 may be integrated devices. For example, the information processing device 3 may have a storage unit 52, an information acquisition unit 53, a detection unit 54, an analysis unit 55, and an update unit 56 of the screen transition individualization device 5. Further, the screen transition individualizing device 5 may have a storage unit 34 and a processing unit 35 of the information processing device 3. Further, each of the information processing device 3 and the screen transition individualizing device 5 may be realized by a plurality of computer devices connected to the network. In this case, which of the plurality of computer devices is used to realize each of the functional units of the information processing device 3 and each functional unit of the screen transition individualizing device 5 can be arbitrary. Further, one functional unit may be realized by a plurality of computer devices.

Subsequently, the details of the data and processing used by the screen transition individualizing device 5 will be described.

Includes 1 or more. The matter identifier CID is information that uniquely identifies the matter. The operation identifier EID is information that uniquely identifies the screen transition performed according to the operation of the user. Specifically, the operation identifier EID specifies the transition (arc) t of the directed graph G performed by the operation on the screen s. The time τ indicates the time when the operation of the transition t specified by the operation identifier EID is performed on the screen s. The time τ indicates the time when the operation of the transition t is performed. The time τ is used as information indicating the order in which the operations were performed. The screen identifier SID is information that uniquely identifies the screen s on which the operation has been performed. The set D'shows the input data items whose values have been updated by the user's operation on the screen s.

FIG. 5 is a data flow diagram of the screen transition individualizing device 5. The functions of the screen transition individualizing device 5 can be roughly classified into three functions: a wandering operation identification function F1, a screen operation history analysis function F2, and a screen transition diagram generation function F3.

The wandering operation identification function F1 is realized by the information acquisition unit 53 and the detection unit 54. The information acquisition unit 53 acquires the screen transition diagram STD ₀ used by the user U and the screen operation history L of the user U among the screen transition diagram STDs acquired from the development environment of the information system Σ. The detection unit 54 uses the screen operation history L to discriminate between a normal operation and a wandering operation, and detects a screen for wandering purposes. The screen operation history L in which the normal operation and the wandering operation are distinguished is referred to as the screen operation history L ^* .

The screen transition diagram generation function F3 is realized by the update unit 56. The update unit 56 generates a screen transition diagram STD _L in which the screen transition diagram STD ₀ is individualized for the user U based on the information obtained by the screen operation history analysis function F2.

FIG. 6 is a flow chart showing the processing of the screen transition individualizing device 5. The screen transition individualizing device 5 performs the processing shown in FIG. 6 for each user. The screen transition individualizing device 5 performs the processing of steps S1 to S3 by the wandering operation identification function F1, the processing of steps S5 to S9 by the screen operation history analysis function F2, and the screen transition diagram generation function F3. The process of steps S10 to S22 is performed accordingly.

First, the processing of the identification function F1 of the wandering operation will be described. The information acquisition unit 53 of the screen transition individualization device 5 reads the screen configuration information indicating the user's screen transition diagram STD ₀ from the storage unit 52 (step S1). Further, the information acquisition unit 53 reads the user's screen operation history L (FIG. 3) from the storage unit 52 (step S2). The detection unit 54 identifies the wandering operation included in the operation indicated by the screen operation history L (step S3).

The screen transition of the reference numeral M1 and the screen transition of the reference numeral M3 in the screen transition diagram STD ₀ are due to a normal operation, and the screen transition of the reference numeral M2 is due to a wandering operation (wandering). The wandering start screen of the wandering operation M2 is the DemandForecastExecutionScreen screen, and the screen for the purpose of wandering is the CustomerEditScreen screen.

Note that (S ₀ , T ₀ ), D ₀ , In ₀ , and Out ₀ are the directed graph G = (S, T) in the screen transition diagram STD ₀ , the entire set D of the data items arranged on the screen, and the screen. The set In of the input data items to be arranged and the set Out of the input data items arranged on the screen. Further, j (j is an integer of 1 or more) is an operation order.

L [i] [j] is said to be an operation at the beginning of wandering when the following (a1) and (a2) are satisfied.
(A1) L [i] there is no input data item to update the value on the screen _{s j} of the [j]. That is, D _j = φ.
(A2) The screen s _{(j + 1)} of the operation L [i] [j + 1] immediately after the operation L [i] [j] is the operation L [i] immediately before the operation L [i] [j]. i] Screen s _(j-1) of [j-1]. That is, s _{(j + 1)} = s _(j-1) .

When L [i] [j] is the operation at the beginning of wandering, L [i] [k] is called the operation at the end of wandering when the following (b1) and (b2) are satisfied.
(B1) screen _{s k} of L [i] [k] is the same screen _{s j} and began to wander. That is, _s j = _{s k.}
(B2) There is no operation having the same screen as the screen s _j between L [i] [j] and L [i] [k]. That is, ∀l ∈ (j, k): s _l ≠ s _j .

The wandering operation L [i] [j] specified above to the wandering operation L [i] [k] immediately before the wandering operation _el (j ≦ l <k, l are integers) That is. In addition, an operation that is not a wandering operation is called a normal operation. The wandering end operation is not a wandering operation but a normal operation.

(C2) For all operations L [i] [m] (m ∈ (l, k)) from L [i] [l] to L [i] [l + 1], the next operation [i] ] [M + 1] screen s _{(m + 1)} is not the screen s _(m-1) of the previous operation [i] [m-1].

Detector 54, a screen operation history L _0, operation begins wander is detected, the end hover operation, hover operations and normal operation, adding a hover start screen, wandered end screen and wander have information on the screen object, screen operation Let it be history L ^* .

Next, the processing of the screen operation history analysis function F2 will be described. As shown in FIG. 6, after the process of step S1~ step S3, the analysis unit 55, by using a screen transition diagram STD ₀ and screen operation history ^{L *,} a screen frequency of visits _{SF L (SF L: S 0} → N ), screen visit probability _{SP L (SP L: S 0} → [0,1]), transition occurrence frequency _{TF L (TF L: T 0} → N), the transition probability _{TP L (TP L: T 0} → [0 , 1]), data reference frequency _{DF L (DF L: D 0} × D 0 → N) and a data reference probability _{DP L (DP L: D 0} × D 0 → [0,1]) is calculated (step S4 ~ Step S9). Note that N represents a set of all natural numbers.

The analysis unit 55 calculates SF _L (s), which is the screen visit frequency SF _L of each screen s (step S4). SF _L (s) is the number of times the screen s is visited in the operation indicated by the screen operation history L, and is defined as follows.

SF _L (s) = | {L [i] [j] ∈ L | L [i] [j] screen = s} |

SP _L (s) = SP _L (s) / max _{s'∈ S0} {SF _L (s')}

In addition, max represents the maximum value. In addition, S0 in the subscript of max represents the _{S 0.} That is, the denominator of the right side of the above equation indicates the maximum value of the screen visit frequency SF _L of each screen s included in the screen transition diagram STD _0.

The analysis unit 55 calculates TF _L (t), which is the transition occurrence frequency TF _L of each transition t (step S6). TF _L (t) is the number of times the transition t has occurred in the operation indicated by the screen operation history L, and is defined as follows.

_{TP L (t) = TP L} (t) / max t'∈T0 {TF L (t ')}

Incidentally, T0 in subscript of max represents _{T 0.} That is, the denominator on the right side in the above equation indicates the maximum value of the transition occurrence frequency TF _L of each transition t included in the screen transition diagram STD ₀ .

Analysis section 55 calculates the input data item _{d in} and a reference data item _d data reference frequency for _out DF _L a is data reference frequency _{DF L (d in, d out} ) ( step S8). DF _L (d _in , d _out ) is the number of times that the data item d _out, which is the reference data, is referred to when a value is input to the data item d _in . In the case of normal operation, the output data item of the same screen as the data item d _in the reference data item. However, in the case of the operation at the end of wandering, the output data item of the screen for the purpose of wandering is also used as reference data. DF _L (d _in , d _out ) is defined as follows.

DF _L (d _in , d _out ) = | {L ^* [i] [j] ∈ L ^* |
(I) When L ^* [i] [j] is a normal operation, d _in is the input data item updated in L ^* [i] [j], and d _out is L ^* [i] [j]. Screen output data item,
(Ii) When L ^* [i] [j] is the end of wandering operation, d _in is the input data item updated in L ^* [i] [j], and d _out is L ^* [i] [ j] screen and screen operation history L ^* output data item of the screen for wandering purpose)} ｜

Analyzing unit 55, the input data item _{d in} and reference data reference probability is the data reference probability DP _L for the combination of the data item _{d out DP L (d in,} d out) is calculated (step S9). _{DP L (d in, d out} ) , when inputting a value to the data item _{d in,} the probability of referring to the the reference data data item _{d out,} is defined as follows.

_{DP L (d in, d out} ) = DF L (d in, d out) / max (din ', dout') ∈D0 × D0 {TF L (d in ', d out')}

In addition, din', dout', and D0 in the subscript of max represent d _in , d _out , and D ₀ , respectively. That is, the denominator of the right side in the above equation indicates the maximum value among the screen operation history L ^* all input data obtained from the item d _in and reference data item d each data reference frequency combination of _out DF _L.

Screen operation history L ^* that distinguishes between normal operation and wandering operation Screen visit frequency SF _{L *} , screen visit probability SP _{L *} , transition occurrence frequency TF _{L *,} and transition occurrence probability TPL _* are also the above screen visit frequency SF _{L *.} , Screen visit probability SP _{L *} , transition occurrence frequency TF _{L *,} and transition occurrence probability TPL _* are defined and calculated in the same manner. In addition, these subscripts L ^* represent L ^* .

FIG. 9 is a diagram showing an example of the transition occurrence frequency TF _{L *} and the transition occurrence probability TPL _* . The transition t (x1, x2) indicates the transition from the screen x1 to the screen x2. Figure 10 is a diagram showing an example of a data reference frequency DF _L. Figure 11 is a diagram showing an example of a data reference probability DP _L. In FIGS. 10 and 11, the heading of each row on the left side indicates d _in, and the heading of each column on the upper side indicates d _out .

Next, the processing of the screen transition diagram generation function F3 will be described. As shown in FIG. 6, after the processing of steps S4 to S9, the update unit 56 changes the screen transition diagram STD ₀ based on the information obtained from the screen operation history L by the analysis function F2. That is, when the information calculated by the analysis unit 55 matches any of the conditions C1 to C6, the update unit 56 makes changes to the screen transition diagram STD ₀ corresponding to the matching conditions (step S10). ~ Step S21). The update unit 56 changes the screen transition diagram STD ₀ by repeating the processes of steps S10 to S21 until there is nothing that satisfies the conditions C1 to C6.

The update unit 56 determines whether or not the information calculated by the analysis unit 55 satisfies the condition C1 (step S10). When the update unit 56 determines that there is information satisfying the condition C1, the update unit 56 replenishes the display items on the screen (step S11). The condition C1 is a condition that, in the operation indicated by the screen operation history L, when a value is input to the data item d _in on the screen s, the data item d _{out on} another screen s'is frequently referred to. The separate screen s'is a screen for the purpose of wandering. Condition C1, the threshold _{w1 <DP L (d in,} d out) denoted. Update unit _56, when the _{DP L (d in, d out} ) is determined to meet the conditions C1, the screen s, add the Out (s').

FIG. 12 is a diagram showing an example of replenishing display items on the screen. As shown in FIG. 12A, in the screen transition diagram STD ₀ , the set of input data items on the screen s is In (s), the set of output data items is Out (s), and the input data on the screen s'. The set of items is In (s'), and the set of output data items is Out (s'). When inputting a value to the data item d _in included in the set of input data items In (s) on the screen s, refer to the data item d _out included in the set Out (s') of the output data items on the separate screen s'. If the frequently _{occurring, DP L (d in, d} out) satisfies the conditions C1. In this case, as shown in FIG. 12B, the update unit 56 adds the set Out (s) of the output data items of the separate screen s'to the set Out (s) of the output data items of the screen s. That is, Out (s) ← Out (s) ∪Out (s').

The update unit 56 may not replenish the display items when the predetermined conditions are met. The predetermined condition is, for example, when the number of output data items included in the set Out (s ") when it is assumed that the display items are replenished exceeds the threshold value, or the input data included in the set In (s"). This is the case where the total number of the number of items and the number of output data items included in the set Out (s ") exceeds the threshold value.

In the process of FIG. 6, when the update unit 56 determines that there is no information satisfying the condition C1, it determines whether or not the information calculated by the analysis unit 55 satisfies the condition C2 (step S12). When the update unit 56 determines that there is information satisfying the condition C2, the update unit 56 integrates the screens (step S13). The condition C2 is a condition that, in the operation indicated by the screen operation history L, when a value is input to the data item d _in on the screen s, the data item d _{out on} another screen s'is frequently referred to. Condition C2 is a threshold value _{w2 <DP L (d in,} d out) denoted.

As shown in FIG. 13A, in the screen transition diagram STD ₀ , the set of input data items on the screen s is In (s), the set of output data items is Out (s), and the input data on the screen s'. The set of items is In (s'), and the output data item is Out (s'). When inputting a value to the data item d _in included in the set of input data items In (s) on the screen s, refer to the data item d _out included in the set Out (s') of the output data items on the separate screen s'. If the frequently _{occurring, DP L (d in, d} out) satisfies the condition C2. In this case, as shown in FIG. 13B, the update unit 56 generates a screen s "integrating the screen s and the screen s'. A set of input data items of the screen s" In (s ") ← In. (S) ∪In (s'), and the set of output data items Out (s ”) ← Out (s) ∪Out (s').

Note that the update unit 56 may not integrate the screens when the predetermined conditions are met. The predetermined condition is, for example, that when the number of input data items included in the set In (s ") when the screens are integrated exceeds the threshold value, the output data items included in the set Out (s") When the number exceeds the threshold value, or when the total number of the number of input data items included in the set In (s ") and the number of output data items included in the set Out (s") exceeds the threshold value.

In the process of FIG. 6, when the update unit 56 determines that there is no information satisfying the condition C2, the update unit 56 determines whether or not the information calculated by the analysis unit 55 satisfies the condition C3 (step S14). When the update unit 56 determines that there is information satisfying the condition C3, the update unit 56 divides the screen (step S15). Condition C3 has two input data items d in ₁ and input data item d in _{2 on} the screen s, and the operation of inputting a value in the input data item d in ₁ and the operation of inputting a value in the input data item d in ₂ are independent. It is a condition that there is. The condition C3 is expressed as (∀d _out ∈ Out (s): DF _{L *} (d _in1 , d _out ) + DF _{L *} (d in ₂ , d _out ) = SF _{L *} (s) −α). α is 0, or a predetermined small positive value. When the update unit 56 determines that the condition C3 is satisfied, the update unit 56 divides the screen s into a screen s1 for setting the value of the input data item d in ₁ and a screen s2 for setting the value of the input data item d in ₂ .

FIG. 14 is a diagram showing an example of dividing the screen. As shown in FIG. 14A, the set of input data items on the screen s is In (s), and the set of output data items is Out (s). In (s) includes an input data item d in ₁ and an input data item d in ₂ . When the operation of inputting a value to the input data item d in ₁ and the operation of inputting a value to the input data item d in ₂ on the screen s are independent, the condition C3 is satisfied. In this case, as shown in FIG. 14B, the update unit 56 divides the screen s into a screen s1 for setting the value of the input data item d in ₁ and a screen s2 for setting the value of the input data item d in _2. To do. The set Out (s1) of the output data items on the screen s1 and the set Out (s2) of the output data items on the screen s2 are the set Out (s) of the output data items on the screen s. That is, the input data item on the screen s1 is d in ₁ , the output data item is Out (s), the input data item on the screen s2 is d in ₂ , and the output data item is Out (s).

FIG. 15 is a diagram showing an example of the transition of the divided screens s1 and s2. Before the division of the screen s, in the screen transition diagram STD ₀ , the screen s is a transition (s _a , s), (s, s _a ), (s, s _b ), (s, s _b ) in both directions with the screen s _a and the screen s _b, respectively. It has s _b , s). In this case, as shown in FIG. 15A, the update unit 56 displays the screen s1 as a transition (s _a , s1), (s1, s _a ) in both directions with the screen s2, the screen s _a, and the screen s _b, respectively. ), (S1, s _b ), (s _b , s1), (s1, s2), (s2, s1), and the screen s2 is in both directions of the screen s1, the screen s _a, and the screen s _b. Screen transition diagram STD ₀ so as to have transitions (s1, s2), (s2, s1), (s _a , s2), (s2, s _a ), (s2, s _b ), (s _b , s2). change. Alternatively, as shown in FIG. 15B, the update unit 56 displays the screen s1 as a transition (s _a , s1), (s1, s _a ), (s1, s2) in both directions with the screen s _a and the screen s2, respectively. ), (S2, s1), and the screen s2 has transitions (s1, s2), (s2, s1), (s2, s _b ), (s _b , s2) in both directions with the screen s1 and the screen s _b, respectively. ) May be changed in the screen transition diagram STD ₀ .

If there is _a transition (s _a , s) from the screen s _a to the screen s before the division and there is no transition (s, s _a ) from the screen s to the screen s _a , the update unit 56 will perform the transition in FIG. 15 after the division. The transitions (s1, s _a ) and (s2, s _a ) in ( _a ) are not generated, and the transitions (s1, s _a ) in FIG. 15 (b) are not generated. If there is a transition (s, s _b ) from the screen s to the screen s _b before the division and there is no transition (s _b , s) from the screen s _b to the screen s, the update unit 56 will perform the update unit 56 after the division in FIG. The transitions (s _b , s1) and (s _b , s2) in (a) are not generated, and the transitions (s _b , s2) in FIG. 15 (b) are not generated. The update unit 56 may generate a transition in both directions between the screen s1 and the screen s2, or may generate a one-way transition from the screen s1 to the screen s2.

In the process of FIG. 6, when the update unit 56 determines that there is no information satisfying the condition C3, it determines whether or not the information calculated by the analysis unit 55 satisfies the condition C4 (step S16). When the update unit 56 determines that there is information satisfying the condition C4, the update unit 56 deletes the screen (step S17). The condition C4 is a condition that the screen s has never been accessed in the operation indicated by the screen operation history L. Condition C4 _is expressed as _{(SF L (s) = 0} ). When the update unit 56 determines that the condition C4 is satisfied, the update unit 56 makes a change so as to delete the screen s from the screen transition diagram STD ₀ . The update unit 56 deletes the transition to the screen s from another screen having the transition to the screen s.

When the update unit 56 determines that there is no information satisfying the condition C4, the update unit 56 determines whether or not the information calculated by the analysis unit 55 satisfies the condition C5 (step S18). When the update unit 56 determines that there is information satisfying the condition C5, the update unit 56 adds a transition (step S19). The condition C5 is a condition that, in the operation indicated by the screen operation history L, when a value is input to the data item d _in on the screen s, the data item d _{out on} another screen s'is sometimes referred to. The condition C5 is expressed as (0 <DP _L (d _in , _out ) <threshold w5 <1). Threshold w5 <threshold w1, threshold w2. The update unit 56 changes the screen transition diagram STD ₀ so as to add the transition from the screen s to the screen s'and the transition from the screen s'to the screen s.

FIG. 16 is a diagram showing an additional example of transition. As shown in FIG. 16A, in the screen transition diagram STD ₀ , the set of input data items on the screen s is In (s), the set of output data items is Out (s), and the input data on the screen s'. The set of items is In (s'), and the set of output data items is Out (s'). When inputting a value to the data item d _in included in the set of input data items In (s) on the screen s, refer to the data item d _out included in the set Out (s') of the output data items on the separate screen s'. If There occasionally _{arise, DP L (d in, d} out) satisfies the conditions C5. In this case, as shown in FIG. 16 (b), the updating unit 56, 'transition to (s, s' in the transition T ₀ from the screen s screen s) and the transition from the screen s' to the screen s (s ', S) is added. This means the establishment of a new link to the screen transition diagram STD ₀ .

When the update unit 56 determines that there is no information satisfying the condition C5, the update unit 56 determines whether or not the information calculated by the analysis unit 55 satisfies the condition C6 (step S20). When the update unit 56 determines that there is information satisfying the condition C6, the update unit 56 deletes the transition (step S21). The condition C6 is a condition that the transition t never occurs in the operation indicated by the screen operation history L. Condition C6 is expressed as (TF (t) = 0). The update unit 56 makes a change to delete the transition t satisfying the condition C6 from the screen transition diagram STD ₀ .

The update unit 56 repeats the processes of steps S10 to S21 until there is nothing satisfying the conditions C1 to C6, and writes the changed screen transition diagram STD ₀ in the storage unit 52 as the screen transition diagram STD _L (step S22). ). The update unit 56 outputs the screen transition diagram STD _L to the development environment of the information system Σ. The development environment of the information system Σ changes the display screen information stored in the information processing device 3 according to the screen transition diagram STD _L. The update unit 56 may change the display screen information stored in the information processing device 3 according to the screen transition diagram STD _L.

In the above embodiment, the screen transition individualizing device 5 personalizes the screen transitions for each user, but the unit for individualizing is arbitrary under the condition that the same screen transition diagram is used. be able to. For example, it may be a unit of a company or an organization that has introduced the information system Σ, a unit of user attributes, or a unit of a project. The attributes of the user are, for example, the department or region to which the user belongs. The information acquisition unit 53 acquires the screen transition diagram and screen operation history of the user belonging to the unit to be individualized.

The order of determination of conditions C1 to C6 may be changed. Further, some of the conditions C1 to C6 may be determined. Further, the update unit 56 illustrates an inquiry screen for inquiring whether or not processing can be executed in all or a part of step S11, step S13, step S15, step S17, step S19, and step S21. It may be displayed on the display unit. When the input unit (not shown) of the screen transition individualizing device 5 inputs whether or not the process can be executed in response to the displayed inquiry screen, the update unit 56 executes the process for which the inquired whether or not the process can be executed, and cannot execute the process. If is entered, the process is not executed. The update unit 56 may display this inquiry screen on the display unit 33 of the information processing device 3. The update unit 56 receives from the information processing device 3 whether or not the user can execute the data input by the input unit 32.

Subsequently, an application example of the screen transition individualizing device 5 will be described. The applicable information system Σ is a power supply system. This power supply system provides the function of determining the supply and demand of electricity every day according to the demand forecast and market conditions. In order for the screen transition individualization device 5 to use this function (corresponding to a matter) of the power supply system, the screen transition is individualized using the screen operation history when three users operate the device of the power supply system. The results and effects of this are shown below. The original screen transition diagram in which the power supply system is not customized is the same as that shown in FIG. In the following, the user with the user name xxx will be referred to as user xxx.

First, the screen transition individualization of the first user desmv will be described.
FIG. 17 is a diagram showing a part of the event log of the user desmv. The event log includes a time (Time), a user name (UserName), a user identifier (UserID), a screen (Screen), and a value (InputData) input to an input data item. The information acquisition unit 53 obtains information equivalent to the screen operation history information shown in FIG. 4 from this event log. Using the event log of the user desmv, the analysis unit 55 uses the screen visit frequency SF _{L *} (s), the screen visit probability SP _{L *} (s), the transition occurrence frequency TF _{L *, the} transition occurrence probability TPL _* , and the data. frequently referenced DF _L, and calculates the data reference probability DP _L.

Figure 18 shows the user's screen frequency of visits desmv _{SF L} * (s) and screen visit probability _{SP L} * (s). Figure 19 shows a transition occurrence frequency of the user desmv _{TF L *} and transition probabilities _{TP L *.} Figure 20 shows the data reference frequency DF _L user Desmv, FIG. 21 shows the data reference probability DP _L user Desmv.

As shown in FIG. 21, it becomes user data reference probability DP L _{(DemandForcast,} WeatherConditions) of desmv = 0.8 and. Updating unit _{56, DP L (DemandForcast, WeatherConditions)} = 0.8> for w1 = 0.5, it is determined to satisfy the condition C1. This means that in order to enter the value of the input data item DemandForcast of the screen DemandForcastExecutionScreen, the value of the output data item WeatherConditions of the screen CustomerEditScreen is frequently referred to. Therefore, the update unit 56 performs the process of step S11 shown in FIG. That is, the update unit 56 replenishes the screen DemandForcastExecutionScreen with the data items of the screen CustomerEditScreen. FIG. 22 is a diagram showing a screen transition diagram in which this change has been made. In FIG. 22, the screen DemandForcastExecutionScreen is replenished not only with the output data items of the screen CustomerEditScreen but also with the input data items.

FIG. 23 is a diagram showing the effect of changing the screen transition. The figure shows the change in the number of screen transitions per day. In the system before the improvement, the screen transition by the normal operation occurred on average 6.2 times, and the screen transition by the wandering operation occurred on average 9.2 times. After the improvement, the number of screen transitions due to wandering was 0, and the number of screen transitions due to normal operation was 5. In this way, the screen transitions due to the wandering operation could be reduced by 9.2 times, and the screen transitions due to the normal operation could be reduced by 1.2 times. The reduction rate is 67.5%.

Next, the screen transition individualization of the second user abb will be described.
FIG. 24 is a diagram showing a part of the event log of the user abb. The information acquisition unit 53 obtains information equivalent to the screen operation history information shown in FIG. 4 from this event log. Using the event log of the user abb, the analysis unit 55 uses the screen visit frequency SFL _* (s), the screen visit probability SPL _* (s), the transition occurrence frequency TF _{L *, the} transition occurrence probability TPL _* , and the data. frequently referenced DF _L, and calculates the data reference probability DP _L.

Figure 25 shows the user's screen frequency of visits abb _{SF L} * (s) and screen visit probability _{SP L} * (s). Figure 26 shows a transition occurrence frequency of the user abb _{TF L *} and transition probabilities _{TP L *.} Figure 27 shows the data reference frequency DF _L user abb, FIG. 28 shows the data reference probability DP _L of user abb.

As shown in FIG. 27, it becomes user data reference probability DP L _{(DemandForcast,} WeatherConditions) of abb = 0.4 and. Updating unit _{56, DP L (DemandForcast, WeatherConditions)} = 0.4> for w3 = 0.3, it is determined to satisfy the condition C3. This means that in order to enter the value of the input data item DemandForcast of the screen DemandForcastExecutionScreen, the value of the output data item WeatherConditions of the screen CustomerEditScreen is frequently referred to. Therefore, the update unit 56 performs the process of step S15 shown in FIG. That is, the update unit 56 adds a transition in both directions between the screen DemandForcastExecutionScreen and the screen CustomerEditScreen. FIG. 29 is a diagram showing a screen transition diagram in which this change has been made.

FIG. 30 is a diagram showing the effect of changing the screen transition. The figure shows the change in the number of screen transitions per day. As shown in the figure, conventionally, the screen transition by the wandering operation was performed 4.9 times on average, and the screen transition by the normal operation was performed 5.5 times on average. After the improvement, the screen transition by the wandering operation was 2 times, and the screen transition by the normal operation was 5 times. In this way, we succeeded in reducing the screen transitions by 2.9 times for the wandering operation and 0.5 times for the normal operation. The reduction rate was 33%.

Next, the screen transition individualization of the third user acc will be described.
FIG. 31 is a diagram showing a part of the event log of the user acc. The information acquisition unit 53 obtains information equivalent to the screen operation history information shown in FIG. 4 from this event log. Using the event log of the user acc, the analysis unit 55 uses the screen visit frequency SFL _* (s), the screen visit probability SPL _* (s), the transition occurrence frequency TF _{L *, the} transition occurrence probability TPL _* , and the data. frequently referenced DF _L, and calculates the data reference probability DP _L.

FIG. 32 shows the screen visit frequency SF _{L *} (s) and the screen visit probability SPL _* (s) of the user acc. Figure 33 shows a transition occurrence frequency of the user acc _{TF L *} and transition probabilities _{TP L *.} Figure 34 shows the data reference frequency DF _L user acc, FIG. 35 shows the data reference probability DP _L of user abb.

As shown in FIG. 35, since the user acc does not refer to the data from other screens, it can be seen that the user acc can operate only by the normal operation. Normal operation is also divided into cases where the screen is detoured to CustomerEditScreen and cases where it is not.

FIG. 36 shows a comparison of the number of screen transitions between the case where the user acc detours to the screen CustomerEditScreen and the case where the user acc does not. As shown in FIG. 33, there are two types of normal operations for the user acc, but since the conditions C1 to C6 of the screen transition individualizing device 5 do not apply, the screen transition is maintained as it is.

From the above application example, it can be seen that the screen transition can be improved so as to reduce the load on each user individually.
