传统的面向过程的流程模型很好支持了单案例类型、步骤明确的业务流程建模和自动化。面对案例类型数和步骤不确定的复杂业务流程、以数据为中心或知识密集型协作过程的自动化需求，传统业务流程模型难以表达。为此，本项目提出了一种面向业务对象的业务流程模型BOOM，并研究其表达能力、合理性和运行机制。首先，基于Artifact-Centric过程模型成果，引入面向对象思想和标准化状态机语义，提出业务对象的概念和面向业务对象的业务流程建模方法，并研究该方法构建的BOOM与传统流程模型的融合方法；接着，对BOOM的表达能力与传统流程模型和新一代模型进行对比评估；进而研究BOOM的合理性验证方法，以分析其表达的过程逻辑的正确性；最后，研究BOOM的运行机制和引擎原型，并以复杂任务众包等典型场景为例进行模型和原型验证。研究成果将增强业务流程模型的表达能力，拓宽其应用范围，并促进分布式计算、软件工程相关研究的发展。

Traditional process-oriented process models provide good support for single-case-type, Step determined business process modeling and automation.Traditional business process models are difficult to meet the needs of process modeling and automation in the face of complex business processes with uncertain number of case types and steps, as well as data-centric or knowledge-intensive collaborative processes.Therefore, this project proposes a Business-Object Oriented Model(BOOM), and further studies its expressive ability, soundness and running mechanism.Firstly, on the basis of achievements in Artifact-Centric process model, object-oriented thinking and standardized state machine semantics are introduced, the concept of Business Object and a Business-Object oriented business process modeling method are put forward,and the fusion method for BOOM and traditional business process model is studied. Then, BOOM's expressive ability is compared with some well-known traditional business process models and new models.After that, the soundness verification method of BOOM is studied to analyze the correctness of its process logic.Finally, the running mechanism and a workflow engine prototype of BOOM are studied, and the model and prototype are validated by taking typical scenarios such as crowdsourcing of complex tasks as examples.The research results will enhance the expressive ability of business process model, broaden its application scope, and promote the development of related researches in distributed computing and software engineering fields.
