目前,电子政务系统一般通过业务过程模型支持电子政务业务处理,而当前已有的业务过程模型在灵活性和安全性方面尚存在不足。为此,提出了一种适合于电子政务中业务处理的过程模型,它将多变的业务规则从过程流中分离出来,通过耦合机制实现业务规则与过程流的结合。该模型简化了过程流的定义,使过程流的变更相对容易,而且可以在不改变过程流的情况下独立、便捷地维护业务规则,确保业务处理的安全性。最后给出了一个使用该模型的电子政务业务处理应用实例。 相似文献

业务过程管理中基于组织和角色语义的访问控制 总被引:1,自引:0,他引:1
针对现有业务过程访问控制方法不能充分满足业务过程管理(BPM)实际需求的问题,首先分析了基于角色的访问控制(RBAC)和基于任务的访问控制(TBAC)等方法的不足;然后提出了一种基于组织结构和角色语义的访问控制(OR-SBAC)模型和方法,并采用形式化方法描述了OR-SBAC模型及其部件;最后给出了OR-SBAC的应用案例.OR-SBAC进一步划分了角色和受控主体,使用企业的组织结构进行用户与角色间的关联,在角色授权过程中通过角色适配器,基于一阶谓词逻辑进行角色语义推理,并考虑了时间和空间上下文等问题.OR-SBAC方法的描述能力强,权限分配效率高,能够满足业务过程管理中访问控制的复杂性、多样性和灵活性等方面的需求. 相似文献

针对目前业务过程修改和实例迁移系统对使用者的技术背景要求较高的问题,提出了一个面向业务人员的动态业务过程改变方法,进行了一致性分析,并给出了业务过程设计器。业务过程设计器基于业务过程模型和符号2.0规范。该规范易于业务分析人员掌握及建模,并具有可执行语义。针对由于业务过程重组导致的业务过程改变的常见模式,提出了业务过程改变操作类型。业务过程设计器支持业务过程改变操作类型,将IT人员解放出来,降低了业务人员与IT人员交流的成本。 相似文献

工作流提倡过程逻辑与业务逻辑分离的理念,然而,业务过程中普遍存在的过程-业务动态关联的特性使这一理念在实际中难以得到贯彻,过程控制与业务处理常常以程序代码的形式耦合在一起,导致业务过程建模复杂,过程重构工作量大且不易实施。分析了WFMC元模型在过程逻辑表示方法上的局限性和难以支持业务过程简便重构的原因,提出了一种新的过程元模型—ESR元模型,在模型中加入了事件、状态和规则等模型元素,能够以规范的形式通过过程定义的方法表示过程-业务的动态关联;基于ESR元模型的工作流模型框架清晰划分了过程逻辑与业务逻辑的界限,对"刚性过程"和"柔性过程"使用统一的过程定义方法进行建模,更好地支持了过程逻辑与业务逻辑的分离;当过程逻辑发生变化时,根据不同的变化内容,可以在不同的模型层次上对过程定义进行修改以应对系统变更的需求,从而实现过程的简便重构。 相似文献

Today businesses are interacting and collaborating more often in the context of a business value chain involving a variety of partners to deliver products and services. Business to business (B2B) connectivity, Enterprise Application Integration (EAI) and general business collaboration processes are becoming more critical in operating and managing efficient enterprises. The required level of inter and intra enterprise integration is generally a large undertaking and involves substantial development and customization efforts. In this paper, we propose an adaptive integration activity management approach based on web services technologies to reduce code changes associated with business process integration in a distributed collaboration environment. Specifically, we present a concept of activity chain to capture non-deterministic process flows as well as deterministic process flows in a uniform manner. Then an Activity Ontology is introduced to capture the integration requirements that include adaptation behaviors, action properties, business rules, and access control policy references. The unique ontology representation and management of the integration activities provides a uniform way to integrate additional internal and external business applications to reduce the need for pre-defined and hard-wired integration methods and to minimize code changes to existing components in an existing business collaboration and integration (B2B/EAI) infrastructure. In addition, a Petri-Net modeling exercise of the proposed integration activity management is performed to help better understand the actual system and improve the system design beforehand. 相似文献

为满足虚拟企业业务流程经常调整的需求,需采用一种可变的业务流程建模模型,便于业务人员在不需IT人员干预的情况下能够对已有业务流程进行修改或重新搭建新的系统。提出了一种基于知识的可变业务流程建模模型,采用业务模板与规则知识库,通过对业务目标分析、检索业务模板,从而定制新的业务流程。在建模过程中使用规则引擎对规则进行校验。业务人员不需对已有业务流程进行大规模重建,提取相应模板进行组合配置即可。 相似文献

A company??s competitiveness relies heavily on its business processes and accurate knowledge to execute its business processes with agility and efficiency. Business Process Management (BPM) initially promised to provide the business world with suitable tools and techniques for successful BPM without help from the IT world. However, the current practice of BPM has several fundamental problems, including difficulty with automatic discovery and the integration of business processes across organizations. Understanding that the main cause of these problems lies in the lack of semantics on business process, we first define a variety of business process ontologies in order to build a semantic business process space (SBPS) for the limited area of sales order. We then explain how the SBPS satisfies the requirements for successful implementation of semantic BPM (SBPM) and demonstrate with a scenario how SBPM can be realized in the environment of SBPS. Our novel approach will reduce the time and cost necessary for the development of a new business process in a fast-changing environment and provide practitioners with useful insights into the proper implementation of the SBPM. Although our paper defines semantic business process knowledge for only a limited domain, its insights can be readily extended to other areas of business. 相似文献

The paper presents the implementation of Business Process Management in a large international company. The business case illustrates
the main objectives and approach taken with the BPM initiative. Central element of the BPM implementation was the development
of a process framework which consists of a reference process house (RPH) and common methods for process management across
the company. In order to assess the implementation of Business Process Management and the achievements a process management
maturity assessment was developed and implemented. The maturity model is based on nine categories which comprehensively cover
all aspects which impact the success of Business Process Management. Some findings of the first assessment cycle are pinpointed
to illustrate the benefits and best practice exchange as a result of the assessment. 相似文献
