面向服务环境下基于本体映射的多领域业务过程协同*

为解决面向服务环境下多领域业务过程协同中的语义不一致问题,使不同领域提供的Web服务实现无障碍交互以及数据和知识共享,提出基于本体映射的多领域业务过程协同框架。首先根据领域知识建立参考本体,然后根据各领域的参考本体生成领域间的协同本体,最后将协同本体通过映射转换到BPEL和WSDL文件。该方法能够保留流程与Web服务中的原始语义信息,从而保证不同领域业务过程协同地顺利进行。原型系统在欧盟ImportNET项目中得到了验证。

A machining process planning activity model for systems integration

A key issue of integrating process planning systems with design systems and production planning systems is how to overcome barriers in data exchange and sharing amongst software systems. A machining process planning activity model was developed to address some of the barriers. This model represents functional components and data requirements in process planning systems. The purpose of the model is to create the context in which data requirements and data flow for numerically controlled machining process planning are defined. Furthermore, the model was developed as a unification of many previously developed process planning activity models.     

基于BPEL的流程数据竞争问题研究

服务组合就是将多个基本的Web服务组合成可以满足用户需求的增值服务,为企业或企业间的业务过程集成提供技术支持。作为一种流程驱动的服务组合描述语言,BPEL和其他采用不同方式的服务组合语言一样面临着流程描述的正确性问题,在执行服务组合之前要对其控制流和数据流进行分析和验证。数据竞争是BPEL数据流分析中亟需解决的问题之一。围绕BPEL流程数据竞争问题,在对BPEL规范中的活动类型、活动并发性进行分析基础上,给出了数据竞争的形式化描述,提出一种检测方法。该方法基于XML节点树的特性、活动之间的并发性以及活动关联的消息来判断是否存在潜在的数据竞争。最后,通过一个订单处理流程实例,说明了该方案的有效性。     

CoBTx-Net: A model for business collaboration reliability verification

Collaborative business process can become unreliable when business partners collaborate in a peer- based fashion without central control. Therefore, reliability checking becomes an important issue that needs to be dealt with for any generic solution in managing business collaboration. In this paper, we propose a novel Choreographical Business Transaction Net (CoBTx-Net) to model collaborative business process and to manage the collaboration by individual participants. Furthermore three reliability properties named Time-embedded dead marking freeness, Inter-organizational dead marking freeness, and Collaborative soundness are defined based on CoBTx-Net to verify (1) the violation of time constraint, (2) collaborative logic conflicts, and (3) the improper termination from individual organizations.

Establishing a systems integration process intrastructure

With the steady fall of prices and margins of computer hardware, back in the 1980s, many hardware manufacturers have tried to diversify their range of offerings. Bull Information Systems has chosen to change its major business direction to become a systems integrator and solution supplier. It has been a real challenge and a big success for Bull to succeed in changing its business direction from being a hardware/software mannfacturer to becoming a leading systems integration (SI) company. For a business to be successful in making such a change it needs to work more efficiently and to react faster, while preserving its stability. Although there are many ways for achieving such change, the experience highlighted in this paper describes how a process focus played a critical part in realizing such change. Creating a systems integration business process and a process-focused organization have been critical factors in achieving the change of business direction. A process focus has an impact on the organizational structure; management practices; employees' skills and training; and on measurements of business performance. This paper describes the experiences at Bull Information systems in creating a systems integration business process-focused organization and it outlines the mechanms which are in place to ensure ownership and improvement of the process. It summarizes the main lessons earnt as a result of creating systems integration business processes.

ProcessAtlas: A scalable and extensible platform for business process analytics

In today's knowledge‐, service‐, and cloud‐based economy, an overwhelming amount of business‐related data are being generated at a fast rate daily from a wide range of sources. These data increasingly show all the typical properties of big data: wide physical distribution, diversity of formats, nonstandard data models, and independently managed and heterogeneous semantics. In this context, there is a need for new scalable and process‐aware services for querying, exploration, and analysis of process data in the enterprise because (1) process data analysis services should be capable of processing and querying large amount of data effectively and efficiently and, therefore, have to be able to scale well with the infrastructure's scale and (2) the querying services need to enable users to express their data analysis and querying needs using process‐aware abstractions rather than other lower‐level abstractions. In this paper, we introduce ProcessAtlas, ie, an extensible large‐scale process data querying and analysis platform for analyzing process data in the enterprise. The ProcessAtlas platform offers an extensible architecture by adopting a service‐based model so that new analytical services can be plugged into the platform. In ProcessAtlas, we present a domain‐specific model for representing process knowledge, ie, process‐level entities, abstractions, and the relationships among them modeled as graphs. We provide services for discovering, extracting, and analyzing process data. We provide efficient mapping and execution of process‐level queries into graph‐level queries by using scalable process query services to deal with the process data size growth and with the infrastructure's scale. We have implemented ProcessAtlas as a MapReduce‐based prototype and report on experiments performed on both synthetic and real‐world datasets.     

Managing context in business process management systems

Businesses need to continuously focus on change and innovation in order to survive in dynamic environments. The ability of an organization to deploy appropriate business processes requires that the fit between business processes and systems that support the management of these processes is continuously maintained and evolved. Acquisition and use of the knowledge about the context in which business processes are defined, modified, and implemented can help maintain this fit. We identify requirements for a business process management system (BPMS) capable of managing contextual knowledge. Based on these requirements, we have enhanced KOPeR, a knowledge-based system for business process improvement, with an explanation facility that can acquire and maintain knowledge about the context behind process definitions and design choices. A case study that illustrates the functionalities of this system which is designed to improve the fit between business processes and BPMS is presented.

A conceptual framework for understanding business processes and business process modelling

It is increasingly common to describe organizations as sets of business processes that can be analysed and improved by approaches such as business process modelling. Successful business process modelling relies on an adequate view of the nature of business processes, but there is a surprising divergence of opinion about the nature of these processes. This paper proposes a conceptual framework to organize different views of business processes under four headings. It also aims at providing an integrated discussion of the different streams of thought, their strengths and limitations, within business process modelling. It argues that the multifaceted nature of business processes calls for pluralistic and multidisciplinary modelling approaches.
