CPE=< CPES0,CPES1,…,CPESn,…>
Wherein, contract of service fulfils situation CPE by CPESiSequence composition；
The posteriority status switch occurred during one carrying out of a contract constitutes the contract of service and fulfils situation, a VO operation
In the process, a plurality of contract of service can be related to act up to an agreement, is accordingly, there are multiple contracts of service and fulfils situation, this multiple clothes
Carrying out of a contract scene joint of being engaged in constitutes the collaboration situation of this VO.
Preferably, it includes: management contract fulfillment processes GP and monitoring contract of service that the joint of the contract of service, which abides by JOM,
Situation MPE is fulfiled,
CPPi+1=GP (CPE, CPPi,MPE)
GP is a process, it selects appropriate contract of service to fulfil association according to current service carrying out of a contract situation
View executes, and on the basis of new contract of service contextual status, and the contract of service to be executed acts up to an agreement in next step for selection；
ExceptionTrigger=MPE (CPESi,CPPi)
To fulfil situation MPE be a process to monitoring contract of service, it is by current CPPiIt is performed rear obtained service contract
About fulfil contextual status CPESi+1To CPP iniThe description of succeeding state is compared to pair, normal to execute if the two is coincide, such as
Fruit is misfitted, then triggers abnormal situation processing function ExceptionTrigger.
Preferably, described S1, S2 and 3 phase control cyclic process TriCL of the abnormal situation mechanism of disposition are by situation exception
It analyzes ExcpEnvAnl, collaboration amending plans CFP and modification plan executes FPP and constitutes:
TriCL=ExcpEnvAnl × CFP × FPP
ExcpEnvAnl=PolcyInterpretating (ExcpEnvi,ExcpEnvPOL)
CFP=PolcyInterpretating (CFPi,CFPPOL)
FPP=PolcyInterpretating (FPPi,FPPPOL)
PolcyInterpretating (arg1, arg2) is interpretation of rules actuator, and arg1 is current state, and arg2 is
For the processing rule of arg1 setting；PolcyInterpretating executes arg2, and using arg1 as the ginseng for executing arg2
Number, calls appropriate local function function Fx；ExcpEnvAnl fulfils situation ExcpEnv with abnormal contract of servicei, and be used for
The reason of abnormal management strategy ExcpEnvPOL of analysis is input, and discovery situation occurs extremely, feature and influence, and thus really
Surely the principle CFPPOL of situation exception is handled, and triggers collaboration amending plans CFP process；CFP is according to CFPPOL and current
State determines that abnormal service occur postpones programme FPPPOL, comprising: which service needs to postpone, postpone how long, take
It is engaged in the replacement of supplier, the replacement of current composite task operation plan, and triggers FPP process, FPP is local bottom function, is born
Duty specifically executes FPPPOL.
Preferably, the local business process LBP is the scheduling that local service target is completed by service collaboration

Adaptive step 2:
SAdp_2:ExcpEnvAnl
ExcpEnvAnl=PolcyInterpretating (ExcpEnvi,ExcpEnvPOL)
Start situation anomaly analysis ExcpEnvAnl, analyze and determine abnormal the reason of occurring, feature and influence, and thus
Generate the policy CFPPOL of processing situation exception, the time demand that CFPPOL describes compensation specification, postpones service call；
Adaptive step 3:
SAdp_3: service collaboration side is input with the MultpConpsPOL and CFPPOL that generate in sAdp_1 and sAdp_2,
Generate the policy group POL4sAdap that will be performed；
Adaptive step 4:
SAdp_4: if there is no the demand for postponing service call in the POL4sAdap of sAdp_3, the net being abnormal
Network service provider executes POL4sAdap；If there is the demand for postponing service call in the POL4sAdap of sAdp_3, starting
CFP；CFP estimates the time span that service call is postponed first, then generates FPPPOL, needs to postpone comprising which extraneous services,
And the time span of postponement is assigned to these extraneous services；
SAdp_5:
If sAdp_4 produces FPPPOL, the FPP in claim 4 is activated,
1, the postponement provided is serviced with the service provider agreements being related to；
2, it is successfully completed once providing the negotiation postponed about service, modifies corresponding service supply and demand contract；
3, service consumer executes the POL4sAdap generated in sAdp_3, and continues to execute by original process.
Preferably, if described from evolution sEvl includes: that sAdp_4 or sAdp_5 executes failure, system enters sEvl letter
Number process, executes following steps:
SEvl_1: service consumer proposes to cancel and execute the POL4sAdap that sAdp_3 is generated in revocation, and makees subsequent place
Reason；
SEvl_2: updating ISP's list in CFPPOL, and activate CFP process, replaces ISP, produces simultaneously
Raw new FPPPOL；
SEvl_3: activation FPP process executes according to FPPPOL: selecting new ISP through consultation and sign clothes
Business supply and demand contract, the postponement provided with supplier's negotiation service of subsequent service；
SEvl_4: if FPP runs succeeded, start the execution of new signature service supply and demand contract, and press local business process
The operation of LBP recovery VO；
SEvl_5: if FPP execution is unsuccessful: can not find new ISP, or postpone failing to consultations for subsequent service
Function, then service consumer updates local business process (local business process of standby if it exists): cancelling currently employed local
Operation flow takes the local business process of standby；
SEvl_6: if operation flow is updated successfully, VO develops successfully, and the execution of VO is restarted by standby operation flow；It is no
Then, VO operation failure, dismisses VO, and make necessary subsequent processes.

Specific embodiment
Below in conjunction with attached drawing of the invention, clear, complete description is carried out to the technical solution of the embodiment of the present invention.
1) contract of service fulfils situation
It is to carry out the basis of service collaboration process that contract of service, which fulfils situation, not only supports that collaborative processes are adaptive and drill certainly
The realization of change also supports the operation of VO.Contract of service is fulfiled situation and is constantly changed with the execution standardized in carrying out of a contract agreement,
And the continuous execution newly standardized is driven in turn.
The foundation that contract of service fulfils situation relies on the supply and demand contract towards current business service, is made of 3 parts:
(1.1) essential information of service collaboration --- mark including concluding parties, the business respectively undertaken disposition role
(the specific role that plays the part of in service is supplied, need to be cooperateed with), the validity period of contract, service content (operation or product item, price,
Quantity and relevant explanation), payment method etc..
(1.2) QoS (service quality) guarantees --- the measurement including defining mass parameter and they, and set and be based on these
The seeervice level target SLOs (Service Level Objectives) of definition.
(1.3) carrying out of a contract agreement --- it is expressed as the partially ordered set of carrying out of a contract specification, each specification description service supply and demand
The obligation that both sides undertake when service collaboration is unfolded or the right enjoyed, including activation condition, the off period of regulation enforcement, specification
The posteriority condition of execution, and the processing activity (operation) driven when specification activation.
Exactly carrying out of a contract agreement supports the foundation that contract of service fulfils situation, and the essential information of service collaboration and
QoS guarantee then gives the definition of specification to provide the foundation information.Contract of service is fulfiled situation and is established as follows:
(1.4) the collaboration state description generated after carrying out of a contract regulation enforcement is known as posteriority state, exactly carrying out of a contract mistake
What the posteriority status switch occurred in journey constituted the contract fulfils situation.
(1.5) situation of fulfiling of all service supply and demand contracts combines the collaboration situation for constituting this VO in VO operational process.
(1.6) situation of carrying out of a contract then means that posteriority state is unsatisfactory for the posteriority condition of specification or specification is not being cut extremely
The coaction of its driving was only completed before the time.Exactly abnormal context driven service collaboration and the VOs's based on service collaboration
Adaptive and evolution certainly.
(2) combining for contract abides by
The development of service collaboration is that cooperation companions (service confession, demander) abide by process for servicing the joint of supply and demand contract.
As long as either party violates some specification for including in service supply and demand contract, the exception that contract of service fulfils situation will lead to,
And thus cause it is abnormal adaptive and from evolution processing (.
The joint of contract abides by technology and fulfils context driven by contract of service.(they are formulated 2 macroscopical agreement specifications
Social promoted type E- mechanism in the community Agent) become the basis for realizing the technology:
(2.1) service provider and party in request, which are all abided by by obligation, formulates in the specification of carrying out of a contract agreement, both sides of supply and demand
The obligated mutual posteriority state for reporting the carrying out of a contract specification respectively executed.
(2.2) social activity promoted type E- mechanism has formulated unified " report receives " service, and is configured at service supply and demand
Side, so that the notification of posteriority state can be carried out in a manner of specification.
The technology executes 2 major functions: management contract fulfillment processes and monitoring contract of service fulfil situation.
(2.3) be exactly carrying out of a contract specification posteriority state mutual report so that service both sides of supply and demand can in time and begin
Possess the complete observation for cooperateing with state eventually.
(2.4) self-test of posteriority state and mutually inspection on the basis of complete observation are established, it can be ensured that carrying out of a contract agreement
The timely discovery of compact execution and abnormal situation, and then improve the reliability and robustness of service collaboration.
(3) the 3 phase controls circulation of abnormal situation is disposed
It, will once some coaction violates the corresponding specification that service supply and demand contract includes during service collaboration
It generates contract of service and fulfils situation exception, and enter the 3 phase controls circulation for disposing abnormal situation.
3 phase controls, 3 incremental steps of circulation point: situation anomaly analysis, collaboration amending plans and modification plan are held
Row controls the disposition (Fig. 2) for abnormal situation.All disposition are all driven by corresponding Agent management strategy.
(3.1) situation anomaly analysis --- analysis work is driven by analysis strategy.Once promise breaking occur (violates certain contract
Fulfil specification) event, corresponding analysis strategy triggers (activation), for analyzing the reason of breaking a contract, feature and influence.Instruction promise breaking
The situation of event abnormal (abnormal posteriority state) often activates multiple compensation to standardize, so that benefit damage side (focuses here
In the event of default for keeping service consumer impaired) selection.The comprehensive analysis of selection gist many factors: posteriority condition is (after expectation
Test the condition of state satisfaction), the progress of the overall situation of current carrying out of a contract, VO multiple service collaborations for including, VO hair
Play the business objective of person, using domain knowledge etc..The result of anomaly analysis becomes the principle of disposition promise breaking, for driving collaboration modification
Planning.
(3.2) cooperate with amending plans --- this mutually trigger (activation) planning strategy generate accordingly cooperate with modification plan,
Minimum is influenced with the negative effect or attenuating of eliminating abnormal.The degree of collaboration modification relies on the shadow of compensation regulation enforcement
Sound, the presence of standby ISP, structure of current local business process etc. can be divided into following several types: postpone
Current and subsequent service time, replacement ISP, replacement local business process, the current VO of revocation are provided.Based on planning
Strategy, different degrees of modification plan are established, so that the adaptation and evolution of collaboration show preferable flexible and retractility.
(3.3) modification plan executes --- and this is mutually intended to the modification plan that application execution strategy goes refinement planning mutually to establish.
For example, only instruction updates the supplier of a business service for modification plan, and the activity of new ISP is selected, including ask
It asks intermediary to recommend, hold consultation and contracts etc. with new ISP, will be driven by implementation strategy.
(4) the flexible scheduling of local business process
For the viability for promoting local business process and VO, the present invention develops the flexible dispatching technique of local business process
To reduce offer (and its execution for constraining the specification of the coaction) time-out (cut-off specified more than specification because of extraneous services
Phase) caused by contract of service fulfil situation exception.
Local business process is established as realizing the Agent activity scheduling plan of local target (task).Fig. 3 instantiates as reality
2 local business process (lbps, the local business for showing some hypothesis target of data mining and formulating
processes).Activity is completed by calling an external business service each of during this.Originally despite the presence of calling
Ground service is come the activity completed, but they are not displayed on Fig. 3.
Since the extraneous services provided by Internet have distributivity and uncertainty, by Pmrpbs(application domain is specified
Calling business service bs when the maximum response time that allows) directly as the term of validity Ap of service provisionbs, it is clear that it is not conform to
Reason.Time enough is left for the disposition to event of default, it should allow ApbsIt is sufficiently large, i.e. PmrpbsOnly account for ApbsA small portion
Point.Enable the available starting time limit Asp of service bsbs=Apbs- PmrpbsAs long as, it is intended that in AspbsInterior calling extraneous services bs, just
It can look to service call can be in ApbsIt is interior to complete and (return to response result).
The step of realizing flexible scheduling is as follows:
(4.1) the current local business process lbp term of validity set each extraneous services are distributed to (to press and Pmrpbs
Proportional mode).
(4.2) for each extraneous services bs, move right Apnext-bsLeft part endpoint so that new Apnext-bs=
Mlnext-bs+Apnext-bs, and obtain the approval (negotiating by collaboration) of bs supplier.Here, Apnext-bsInstruction next-bs (after
After business service) term of validity, Mlnext-bsIndicate the time interval being moved to the left, and 0 < Mlnext-bs≤ Aspbs.Obviously,
Mlnext-bsIndicate ApbsWith new Apnext-bsBetween lap (Fig. 4).
(4.3) EAp is enabledbsIt indicates the bs term of validity of extension, and defines EApbs=Aspnext-bs。
(4.4) in lbp implementation procedure, if the offer of bs cannot be in AspbsInterior starting (due to the appearance of situation exception),
Agent as VO manager still can be in (Aspbs+EApbs) in call bs, and do not interfere the normal offer of next-bs
(due to Pmrpnext-bsReservation).
The flexibility (flexibility) of scheduling is embodied in following 3 aspects:
(4.5) overlapping of term of validity helps significantly to reduce under normal situation between the service provided in succession in timing
The execution time of lbp；Especially in Mlnext-bs=AspbsWhen, the interval time serviced between bs and next-bs offer can just disappear
It removes.
(4.6)Apbs(>Pmrpbs) and EApbsSetting, so that the Agent as VO manager is had at time enough
Situation exception is set, while not influencing the regular supply of next-bs again.
(4.7) when the offer of service bs cannot be in (Aspbs+EApbs) in complete when, the offer of bs can only be postponed；But due to
Apbs(>Pmrpbs) and EApbsSetting, only a small number of subsequent services are affected.
(5) VO is adaptive and develops certainly
Supplementary explanation VO adaptive and from evolution relationship and difference below.
The present invention is adaptive by VO and is considered as the means for safeguarding VO from developing, and is able to achieve it still when facing and cooperateing with abnormal
The target (completing some task that VO promoter proposes) (Fig. 5) that dynamic is established when it is set up.This maintenance is divided into 2 ranks
Section: adaptive and evolution certainly.2 stages main difference is that VO variation degree: the former does not change the composition of VO, and the latter is then
It is required that the lbp of VO target is realized in certain members of replacement VO, or even replacement.VO copes with the maintenance work of situation exception always from certainly
Adaptation starts, and only just enters when can not adaptively prove effective from the evolutionary phase.
The VO adaptive stage relies on 2 key technologies: compensating in the flexible scheduling and service supply and demand carrying out of a contract agreement of lbp
The configuration of specification.Abnormal despite the presence of the special situation in various fields, it is identical for disposing their mode:
(5.1) activate multiple compensation specification, the request (conflict resolution request) chosen therefrom is made in foundation, using the request as
Event activates corresponding management strategy,
(5.2) then thus 3 phase control of policy-driven recycles (the analysis phase in circulation).
(5.3) configuration that specification is compensated in policy-driven, flexible scheduling and carrying out of a contract agreement, it is different to not only increase elimination
A possibility that reason border, also promotes viability when current lbp faces situation exception.
(5.4) due to not changing VO member and lbp, the appearance for keeping the quick reply collaboration of VO abnormal.
If the exception that contract of service fulfils situation can not be coped in the adaptive stage, the maintenance of VO enters from evolution rank
Section.Since situation anomaly analysis is completed in the adaptive stage, in 3 phase controls circulation only after 2 phases: collaboration and is repaired amending plans
Change plan to execute, needs to be executed.
