Driven by industrial needs and enabled by the latest information technology, enterprise integration has rapidly shifted from information integration to process integration for performance excellence in the entire business process. This paper reports on the modeling of a business information model which enables mold making companies to achieve business process integration. The needs of process integration in mold making companies are first highlighted. Typical mold making business processes are analyzed and four critical business processes to be integrated are identified. Further, a process-oriented business information model is proposed, which associates business information entities to meet the needs of all business processes. Based on the model, the integration of four critical business processes is investigated, which enables seamless information flows to streamline the business processes, maximize information sharing across the business processes and achieve the automation and concurrency of the business processes. Finally, the implementation and benefits to industry of the system derived from the developed information model is presented.  相似文献

Automatic control of workflow processes using ECA rules   总被引:8,自引:0,他引:8  
Changes in recent business environments have created the necessity for a more efficient and effective business process management. The workflow management system is software that assists in defining business processes as well as automatically controlling the execution of the processes. We propose a new approach to the automatic execution of business processes using event-condition-action (ECA) rules that can be automatically triggered by an active database. First of all, we propose the concept of blocks that can classify process flows into several patterns. A block is a minimal unit that can specify the behaviors represented in a process model. An algorithm is developed to detect blocks from a process definition network and transform it into a hierarchical tree model. The behaviors in each block type are modeled using ACTA formalism. This provides a theoretical basis from which ECA rules are identified. The proposed ECA rule-based approach shows that it is possible to execute the workflow using the active capability of database without users' intervention. The operation of the proposed methods is illustrated through an example process.  相似文献

Process-aware information systems (PAIS) are systems relying on processes, which involve human and software resources to achieve concrete goals. There is a need to develop approaches for modeling, analysis, improvement and monitoring processes within PAIS. These approaches include process mining techniques used to discover process models from event logs, find log and model deviations, and analyze performance characteristics of processes. The representational bias (a way to model processes) plays an important role in process mining. The BPMN 2.0 (Business Process Model and Notation) standard is widely used and allows to build conventional and understandable process models. In addition to the flat control flow perspective, subprocesses, data flows, resources can be integrated within one BPMN diagram. This makes BPMN very attractive for both process miners and business users, since the control flow perspective can be integrated with data and resource perspectives discovered from event logs. In this paper, we describe and justify robust control flow conversion algorithms, which provide the basis for more advanced BPMN-based discovery and conformance checking algorithms. Thus, on the basis of these conversion algorithms low-level models (such as Petri nets, causal nets and process trees) discovered from event logs using existing approaches can be represented in terms of BPMN. Moreover, we establish behavioral relations between Petri nets and BPMN models and use them to adopt existing conformance checking and performance analysis techniques in order to visualize conformance and performance information within a BPMN diagram. We believe that the results presented in this paper can be used for a wide variety of BPMN mining and conformance checking algorithms. We also provide metrics for the processes discovered before and after the conversion to BPMN structures. Cases for which conversion algorithms produce more compact or more complicated BPMN models in comparison with the initial models are identified.  相似文献

SDO2JSON:一种业务数据模型到表现层模型的转换方法   总被引:1,自引:0,他引:1  
企业为适应自身业务的发展和组织结构的变化需要不断改进原有的业务流程,而一旦业务层定义的数据模型发生变化势必会影响到表现层内容的展示,为此需要付出更大的成本重新调整表现层来对齐新的业务流程。针对这一问题,提出一种能反映表现层内容随业务层数据模型变化而动态更新的方法。在此基础上,开发出一种敏捷的从服务数据模型到脚本模型的转换工具,并将此工具应用在基于SOA架构的企业信息系统开发过程中,大大降低了业务流程重组过程中的维护成本。  相似文献

The three basic structural elements of a data processing system are shown to be files, flows, and processes. A metric for the size of a data processing system is introduced which is a function of the number of files, flows, and processes of the system. The validity and reliability of this metric are demonstrated. It is shown how the metric may be used to estimate the cost of developing a data processing system at an early stage in the development process. Furthermore, it is demonstrated how the metric may be used to determine the efficiency of data processing system development.  相似文献

In order for enterprises to collaborate at the business-process level, they must deal with two kinds of processes: the public conversation processes specifying inter-enterprise document flows, and the private business processes specifying local workflows of document manipulation and other related tasks. The provisioning, interaction and integration of conversation management and business process management, have become the common interest of the e-business industry. In this paper we discuss the relationship and interaction between conversation management and business process management; point out the difference between public conversation processes (e.g. BPSS processes) and peer-conversation processes (e.g. BPEL4WS processes). We then illustrate our collaborative process management system that has functionally separated conversation manager and business process manager. The conversation manager is based on the ebXML BPSS standard; it is used for validating document exchange at run-time and for activating corresponding process tasks. We have also proposed the conversation model driven asynchronous task activation mechanism for interaction between a conversation process and the coupled business process dynamically. With this mechanism, generic APIs between the conversation manager and the business process manager can be easily defined and used by multiple plugged-in conversation managers.  相似文献

Nowadays, organizations have to adjust their business processes along with the changing environment in order to maintain a competitive advantage. Changing a part of the system to support the business process implies changing the entire system, which leads to complex redesign activities. In this paper, a bottom-up process mining and simulation-based methodology is proposed to be employed in redesign activities. The methodology starts with identifying relevant performance issues, which are used as basis for redesign. A process model is “mined” and simulated as a representation of the existing situation, followed by the simulation of the redesigned process model as prediction of the future scenario. Finally, the performance criteria of the current business process model and the redesigned business process model are compared such that the potential performance gains of the redesign can be predicted. We illustrate the methodology with three case studies from three different domains: gas industry, government institution and agriculture.  相似文献

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
