Embodiment
The preferred embodiments of the present invention are described with reference to the accompanying drawings:
＜processing summary 〉
Fig. 1 illustrates the ingredient of processing.Processing comprises activity (activity) and shifts (transition).About the term of workflow system, referring to " Workflow Management Coalition TheWorkflow Reference Model " (http://www.wfmc.org/standards/docs/tc003v11.pdf); " Workflow Management Coalition Workflow Standard/Process DefinitionInterface-XML Process Definition Language "
(http://www.wfmc.org/standards/docs/TC-1025_xpdl_2_2005-10-03.pd f), they show concrete definition.
Processing is the treatment scheme of execution work (can be described as operation or task).For processing, the definition process variable is described the state of processing.Treatment variable is as movable beginning condition, end condition, transfer trigger condition or handle end condition.Activity beginning condition and end condition are to be used to be provided with and to stop each movable condition.Shift trigger condition and be mainly used in branch's connection of determining to be branched off into one of a plurality of activities.Whether handle end condition is used for determining to handle finishing fully.Be noted that the value of preserving treatment variable, unless it obviously changed (mentioning after a while) before or after handling the change of example (instance) flow process.
Activity is the operations specific that comprises in handling.Movable can have such as following state: do not carry out as yet, finish, wait for and begin to handle etc.Change between the state can be indicated the progress status of processing.Activity has beginning condition and end condition, and they are described by the conditional of using treatment variable.Movable execution result is stored in the treatment variable, and the change historical storage of storage of variables is record (log).
Shift the processing sequence between the definition of activities.Transfer has state, determines the state transitions condition of coupled activity thus.Change to another movable condition from an activity and be called the transfer trigger condition.Shifting trigger condition mainly describes in the conditional of using treatment variable.
Flow process illustrates movable and shifts represented process flow diagram.
Handling definition is the template of handling, the flow process of definition process before execution.
Handling example is the materialization form of handling definition, and comprises the content of operation.
Handling example process is the flow process of executory processing.Handling example process is the flow definition of handling example, and identical with processing definition originally.Yet, in the present invention, handle example process and be taken as the different object that can operate respectively with handling to define.That is, when revising the processing example process, described modification is by handling the definition reflection.In addition, when revise handling definition, its reflection is also can't help in the processing (processing example) that converts example forms to.
Fig. 2 illustrates treatment state and shifts, and each state is shown: " not carrying out (un-activation) as yet ", " in the execution (activation) ", " time-out " and " finishing ".Here, when the processing of " activation " is stopped, " time-out " state occurs, and, occur " activation " state once more as handling the result who is restarted." time-out " handled is synchronous with " time-out " of activity.
Fig. 3 illustrates active state and shifts, and each state is shown: " not carrying out (un-activation) as yet ", " waiting pending (wait) ", " in the execution (activation) ", " finishing " and " time-out ".When the transfer that connects previously triggered and satisfy movable beginning condition, the activity of " un-activation " entered " wait " state.When relevant work flow process application program provided sign on (describing after a while), the activity of " wait " entered " activation " state.Finish when instruction when receiving from the activity of workflow application, the activity of " activation " enters " finishing " state.Be in the activity of " un-activation ", " wait ", " activation " or " finishing " state and " time-out " of processing and synchronously enter " time-out " state, and when processing turns back to " activation " state, turn back to original state.
Fig. 4 illustrates transfering state and shifts.As shown in the figure, shift state with " opening (on) " and " closing (off) ".When the state in the activity of starting point becomes " finishing " state and satisfies when shifting trigger condition, the transfer that is in " pass " state enters " opening " state.When in the activity of termination locations when " wait " state becomes " activation " state, shift " pass " state that enters once more.

＜operation 〉
Figure 25 illustrates the sequence chart of the processing example when handling beginning.
At first, when the user when workflow application 13 request obtains to handle the definition tabulation (step S1), workflow application 13 is handled definition administrative section 21 and is obtained to handle definition tabulation (step S3) from handling definition database 22 to handling definition administrative section 21 Request Processing definition tabulations (step S2).Workflow application 13 is delivered in thus obtained processing definition tabulation in response, and so that a kind of like this condition that the user can therefrom select show by workflow application.
Then, when the user selects the processing definition of expecting and asks to generate the processing example (step S4), workflow application 13 is to handling definition administrative section 21 Request Processing definition (step S5), and the latter obtains to handle definition (step S6) then from handle definition database 22.Workflow application 13 is delivered in thus obtained processing definition in response, and the parameter (step S7) of workflow application 13 set handlings definition is asked workflow engine 13 to generate then and is handled example (step S8) then.Workflow engine 13 will be handled example and be registered in the processing instance database 24, handle example (step S9) thereby generate.To generate the object of handling example then thus and deliver to workflow application 13 in response.
Figure 26 illustrates and handles the notion that changes, and the processing of being carried out in the time will carrying out real work in the mode that is different from definition originally totally is shown.
In Figure 26, after processing is stopped, workflow engine 23 obtains to handle example process (step S11) from handling instance database 24, and the processing that the workflow engine 23 processing example process that will obtain converts the internal expression form of handling instance database 24 to defines (step S12).Then, processing execution edit tool 12 obtains to handle definition (step S13) from workflow engine 23.
(step S14) edited in 12 pairs of thus obtained processing definition of processing execution edit tool, and request workflow engine 23 is upgraded processing definition (step S15).
Figure 27 illustrates the sequence chart of the processing example when changing processing.In Figure 27, when the user asks workflow application 13 to begin processing example process editor (step S21) during processing execution, workflow application 13 request workflow engine 23 stop to handle (step S22), and workflow engine 23 changes over " time-out " by the state that will handle the processing in the instance database 24 and stops to handle (step S23).The object that processing is stopped to send to workflow application 13 in response.
The user handles example process by 12 pairs of processing execution edit tools and carries out editing operation (step S28).Figure 28 illustrates an example of the graphic user interface (GUI) of processing execution edit tool 12 when interpolation activity (as editor's a example).Here, carry out movable interpolation by following operating process:
(1) in " interpolation " menu 12a, selects " activity ".
(2) from the application list 12b, select " document creation ".
(3) show events is provided with window 12c.
(4) be provided with in activity parameter (title: " patent file establishment " etc.) is set among the window 12c, and press " OK " button.
(5) in " flow process view " window 12e, show events " patent file establishment ".
(6) in " interpolation " menu 12a, select " transfer ", and add and shift 12g.
(7) select " finishing editor " 12h.
Figure 29 illustrates the process flow diagram that system side is used for the processing example of interpolation activity etc.
When the request in response to the interpolation activity begins to handle (step S41), accept the selection (step S42) of workflow application, and produce active instance (step S43).In this case, for the tabulation that shows that workflow application can therefrom be selected, read the application program definition and read table 227 (Figure 14), and carry out the renewal of hotlist 242 (Figure 16) so that produce active instance.
Then, when needs, produce new treatment variable or activity variable (step S44).In this case, read treatment variable definition list 224 (Figure 11) so that obtain the template of treatment variable, and the renewal of treatment variable table 244 (Figure 18) is carried out in generation for this reason.For activity variable, carry out the renewal of activity variable table 245 (Figure 19).Be noted that and use processing defining tool 11 (Fig. 7) that new treatment variable definition is added in the treatment variable definition list 224.
Then, for existing or new treatment variable or the activity variable that produces, proceed to the distribution (step S45) of the selected parameter of workflow application.In this case, carry out the renewal that treatment variable table 244, activity variable table 245 and treatment variable read table 247 (Figure 21).
Then, upgrade treatment variable and read information (step S46).In this case, upgrade treatment variable and read table 247.
Then, interpolation of shifting and setting (step S47).In this case, corresponding renewal transfer table 243 (Figure 17).
Then, increase progressively (adding 1) reading counting or reading more New count (step S48) by a movable or transfer corresponding treatment variable that reads or upgrade that adds.In this case, corresponding renewal treatment variable table 244.
Figure 30 is illustrated in the process flow diagram of the processing example of deletion activity etc. on the system side.
When handling beginning (step S51), the selection of the activity that acceptance will be deleted (step S52), and deletion active instance (step S43).In this case, corresponding renewal hotlist 242 and activity variable table 245.
Then, successively decrease the reading counting or reading more New count (step S54) of a corresponding treatment variable that (subtracting 1) read or upgraded by the movable institute of deletion.In this case, corresponding renewal treatment variable table 244.
Then, deletion is in the movable front of deletion or the transfer (step S55) that connects later.In this case, corresponding renewal transfer table 243.
Then, successively decrease and read counting (step S56) by the treatment variable that reads of transfer of deletion.In this case, corresponding renewal treatment variable table 244.
Then, add new transfer (step S57).In this case, corresponding renewal transfer table 243.
What then, increase progressively the treatment variable that read by the transfer of adding reads counting (step S58).In this case, corresponding renewal treatment variable table 244.
Then, deletion is read counting and is read more that New count all is the treatment variable (step S59) of " 0 ".In this case, corresponding renewal treatment variable table 244.Like this, by the activity of deleting or shift the treatment variable all do not read, can create a kind of like this state, that is, wherein not comprise for again with being the unnecessary processing variable.Be noted that for to handling unique treatment variable, the initial value that reads counting is set in advance be " 1 ", like this, even all read activity or also can not delete it when shifting when deletion.
Return Figure 27, after finishing the editor who handles example process (step S28), user's Request Processing executive editor instrument 12 upgrades handles example process (step S29), and processing execution edit tool 12 request workflow engine 23 are upgraded processing example process (step S30).
The workflow engine 23 that receives this request is checked process object ACL database, changes the authority (step S31) of handling example process to check whether this user (editor) has.When the user does not have when changing authority, notify the user he do not change authority.Like this, prevent from not have the user of authority to change processing.
On the other hand, when the inspection that changes authority was succeeded, workflow engine 23 was handled the inspection (step S32) of the continuity (enforceability) of example process.Figure 31 illustrates the process flow diagram of the processing example of handling the inspection of example process continuity.
In Figure 31, when handling beginning (step S61), use treatment variable table 247 (Figure 21) (step S62) when uppermost activity begins successively Survey Operations and shift the treatment variable that is read.At this moment the particular item that will check for example comprises:
(1) whether the existence of treatment variable;
(2) value of treatment variable (whether the value of having upgraded the last activity of treatment variable falls in the effective range of activity or transfer);
(3) be assigned to this movable task executor and whether have operating right this treatment variable; Know
(4) under situation about shifting, when the institute that whether has covered treatment variable when parallel transfer trigger condition is carried out the OR operation might situation.
Then, when finding any can not be performed movable, give the alarm and ask to update (step S63).
In addition, when the termination activity can't arrive, carry out mistake and determine, and (step S64) updated in requirement.
Therefore, can avoid unnecessarily changing processing, thereby can guarantee enforceability.
Figure 32 illustrates the detail flowchart that continuity is checked, (step S62) handled in the treatment variable inspection that illustrates in greater detail Figure 31.
When the step S101 at Figure 32 begins to handle, to handle example process (step S 102), obtain first activity (step S103), and the treatment variable (step S104) that read of selection activity.
Then, determine whether there is this treatment variable in the treatment variable table 244, and in Access Control List (ACL) 251, check the task executor's of this treatment variable authority (step S105).
When this treatment variable does not exist or authority when wrong (step S106 for not), then determine to occur continuity mistake (step S107), and end process (step S108).
On the other hand, there is and authority when not having mistake (step 106 is for being) probable value (step S109) of acquisition treatment variable from storer when this treatment variable.In the time can obtaining this value (step S110 is for being), obtain the treatment variable definition ID of this treatment variable, obtain the effective value (step S111) of this treatment variable by movable ID and processing definition ID.In the time can obtaining this value (step S112 is for being), between treatment variable effective value and treatment variable probable value, carry out the AND operation, and operating result is stored in (step S113) in the storer as probable value.(step S110 or S112 are for denying) then do not carry out particular procedure in the time can't obtaining this value.
Then, whether the probable value of the treatment variable of storing in definite storer in step S114 satisfies movable beginning condition.(step S114 is NG) then determines to occur continuity mistake (step S107) when condition does not satisfy, and end process (step S108).
(step S114 is OK) then obtains next treatment variable (step S115) when condition satisfies.In the time can obtaining this value (step S116 is for being), then turn back to the treatment variable (step S104) that the selection activity is read.
(step S116 is for denying) then updates stored in the probable value (step S117) of the treatment variable in the storer, and obtains next transfer (step S118) by the end condition of activity in the time can't obtaining this value.
Then, whether the probable value of determining to be stored in the treatment variable in the storer in step S119 satisfies the trigger condition that shifts.(step S119 is NG) then determines to occur continuity mistake (step S120) when condition does not satisfy, and end process (step S121).
When condition satisfies (step S119 is OK), then update stored in the probable value (step S122) of the treatment variable in the storer, and obtain next activity (step S123) by the trigger condition that shifts.
When can the acquisition activity (step S124 is for being), turn back to the first step (step S103) of acquisition activity.When can't the acquisition activity (step S124 for not), determine continuity mistake (step S125) not occur, and end process (step S126).
Figure 33 illustrates the example of continuity mistake.When interpolation activity 3 between the activity shown in (a) 1 and movable 2, shown in (b), movable 1 end condition is P1＞200, therefore when movable 1 end the value of P1 greater than 200.On the other hand, movable 3 beginning condition is P1＜150.Therefore, do not carry out activity 3, thereby can not finish to handle.Therefore, the continuity mistake appears.
Turn back to Figure 27, when the inspection of processing example process continuity does not go wrong (step S32), workflow engine 23 reads treatment variable and changes history lists 246 and determine that processing restarts position (step S33).Figure 34 illustrates the process flow diagram of determining to handle the processing example of restarting the position.
In Figure 34, when beginning to handle (step S71), obtain to handle example process (step S72) from handling instance database 24, obtain first activity (step S73) and the transfer (step S74) of this activity that obtains to continue.Then, read treatment variable and upgrade history lists 246, and in step S75, S76, determine to shift end condition and whether once satisfied.(step S76 is for denying) is defined as restarting position (step S77) with this transfer when condition never satisfies, and end process (step S78).
When this condition once satisfied (step S76 is for being), the activity (step S79) of this transfer that obtains to continue is read treatment variable and is upgraded history lists 246, and determines in step S80, S81 whether the activity end condition once satisfies.(step S81 is for denying) then is defined as this activity to restart position (step S82) when condition never satisfies, and end process (step S78).
When the activity end condition once satisfied (step S81 is for being), determine in step S83 whether this activity is last activity.When it is last activity (step S83 is for being), determines that this processing finishes (step S84), and finish when pre-treatment (step S78).
When it is not last activity (step S83 is for denying), turns back to step S74 and obtain the transfer of this activity that continues, and continue to handle.
Turn back to Figure 27, after definite processing restarts the position (step S33), workflow engine 23 is upgraded the processing example process of handling on the instance database 24 (step S34), and in response to upgrading the result, workflow application 13 request workflow engine 23 restart to handle (step S35), and workflow engine 23 restarts to handle (step S36) by upgrading the status information of handling in the instance database 24.
Figure 35 to 40 illustrates the example of each table when duplicating with the editing and processing example.That is, in aforesaid operations, as handling by the result of " time-out ", processing stops.Edit then, check authority and continuity, restart then.Handle example yet, interrupt (or termination) here, produce its copy, edit thus obtained new processing example, check authority and continuity, restart then.
Figure 35 illustrates a kind of state, and wherein when the processing of editing and processing ID:1, the state of processing becomes " termination ", the data of replication processes, and produce the new example (handling ID:m+1) of handling.
In Figure 36, the information of the activity of replication processes (handling ID:1), having only the information of movable ID and processing ID is new id information, other information then former state are inherited.In addition, interpolation activity and make it belong to the processing of new processing ID (" m+1 " in this example) when needing.
In Figure 37, the transfer of replication processes ID:1 makes " source activity " and " purpose activity " have new movable ID.In addition, interpolation or deletion are shifted when needs.At this moment, when needing, change the trigger condition of each transfer.State by trigger condition and treatment variable/activity variable is determined state automatically.
In Figure 38 and 39, the treatment variable of replication processes ID:1 and activity variable, handling ID and movable ID is new id information, and other information are inherited.In addition, when needs, add new ID of processing and movable ID.In addition, deletion is read counting and is upgraded that to read counting be 0 treatment variable and activity variable.
In Figure 40, duplicate with handle ID:1 in the relevant information that reads of transfer of the activity that comprises, give to make new advances activity ID and shift ID, and inherit other information.In addition, when needs, add and newly read information, perhaps delete the unwanted information that reads.
Registration process definition is shown Figure 41 so that the example of the graphic user interface of the processing defining tool of usefulness again.That is,, can use again in the future by according to becoming the processing example process generation processing definition of carrying out the matched form of mode with user's real work.Here, handle the registration of definition by following operating process:
(1) from " introducing " menu 11a, select to handle example process, and as a result of, right pane becomes handles example list 11b;
(2) from handle example list 11b, select the processing example of expectation, and press " OK " button; As a result, display process example process among on the left side " flow process view " the window 11d, and close and handle example list 11b.
(3) user edits the processing example process that shows in " flow process view " window 11d, selection " interpolation " menu 11e, and execution then will handle example process by processing definition administrative section 21 and define the processing that is registered in the processing definition database 22 as handling.
As mentioned above,, under such situation, edit, that is, stop to handle, check editor's authority and handle continuity, determine to restart the position and restart according to the present invention.Therefore, can avoid the final user to change processing inadequately, can when guaranteeing its enforceability, freely change executory processing.
In addition, can produce improved workflow from the executive logging of activity, and can use again.
