Description

A kind of coevolution method of plug-in type operation flow family

Technical field

The invention belongs to BPM technical field, more particularly to a kind of collaboration of plug-in type operation flow family Evolution method.

Background technology

As increasing business organization is grasped come the business to enterprise using operation flow (also referred to as business procedure) model Model, in an enterprises, often accumulate hundreds of business process model, define business process model storehouse. Comparing famous business process model storehouse at present in the world includes：SAP reference models storehouse and Apromore procedural models storehouse etc..

On the other hand, as cloud computing technology focuses on the reduction of the shared cost realized with enterprise of IT resources, business Flow process services the technology of (Business Process as a Service, BPaaS) and arises at the historic moment, and is accompanied by cloud framework It has been applied in the production of actual industrial.Internationally famous advisory organization Gartner defines BPaaS for " one kind is based on operation flow Service entrust, this service comes from cloud and to realize constructed by multi-tenant ".Multi-tenant flow process --- it is often referred to based on same One procedural model and specialization are in the flow process variant of enterprise --- can run in cloud framework.Some more famous cloud services It is BPaaS, such as：Salesforce, EasyChair etc..In order to create and management business procedural model, current industrial quarters and Academia also occurs in that many instruments, such as：Oracle BPM external members, Apromore Orchestration Designers, Websphere Business Process Modeling device etc..These instruments support that the definition that flow process is realized using different modeling languages, including operation flow are built Mould mark (Business Process modeling notation, BPMN), event-driven process chain (Event-driven Process chain, EPC), UML activity diagrams etc..

In the merger and restructuring of enterprise, from multiple companies or multiple operation flow variants of enterprise (business process variant), generally requires coevolution (co-evolve).Multiple flow process variants condense together Define operation flow family (business process family).Flow process family often runs beyond the clouds that different tissues are not In same business process engine so that it is difficult to use a kind of coevolution of centralized mode management process family.In China's shifting The office automation system of dynamic communication common carrier is exactly a real case.According to investigations, China Mobile is about The office automation flow process of 8000 or so is in operation, and this 8000 flow processs are managed by the branch company of 31 provinces (autonomous region) Manage and safeguard.Each procedural model in flow process family is made, coevolution is realized under the support of business process management system, will The maintenance cost of flow process can be reduced and the generation of discordance is avoided.However, workflow management instrument can not support right at present The management of flow process family coevolution.

The coevolution of flow process family belongs to the research category of flow process transmutability management, although the coevolution of flow process family It is extremely important in industrial practice production, but the method for existing flow process family coevolution is considerably less.From workflow management Life cycle from the point of view of, document [1] summarizes the feature of workflow management, and workflow management is divided into five stages in order： Analysis and design, configuration, execution, diagnosis and evolution.Wherein three phases all have certain association with our method.Dividing Analysis and design phase, a flow process family is designed, models and verifies.By using for reference (Software in software product line engineering Product Line Engineering, SPLE) method, the configurable procedural model of series of different is suggested, PESOA models such as in the C-iEPC models in document [2], the Provop models in document [3] and document [4] etc..Configuration The target in stage is to obtain an executable flow process variant by configuring a configurable procedural model, during configuration Often by the product of some decision supports, such as：The characteristic model in questionnaire model, document [6] in document [5], document [7] In object module, the decision-making table model in document [8], the crosscutting concerns of Process-Oriented in document [9] etc..In flow process Execution stage, the flow process variant after configuration will be created, start and perform, and become in the stage of execution situation to meet The needs of change, dynamic configuration type technology are often requisite.Document [10] proposes a kind of flow process fragment (process Fragment technology), is managed flow process fragment as a kind of knowledge that can be multiplexed, and by these flow process fragments in addition Dynamically, the combination of context aware, forms adaptive, service-oriented application program, document [11,12] propose it is a kind of towards The flow process adaptability framework of service.In addition, document [13,14] it is also proposed a kind of flow process extension (process Extensibility) framework is solving flow process adaptability problem.It is different, in flow process extension framework, reference model The responsibility of the shareholders such as supplier and reference model consumer is cleanly separated.
