基于 Petri 网的复杂装备服务业务流程建模方法

摘要

In order to identify the elements of complex equipment service process and its positions and roles,a business process modeling method of complex equipment based on Petri nets in service life cycle was presen-ted.The time interval boundary was defined and the three-stage division of services business including early, middle and end stage was finished.Then,in analysis of the common elements of service business,and busi-ness activity relationship models and modeling steps based on Petri nets were given.Finally,taking the model-ing of the large vertical mill of ore class manufacturing enterprises as an example,the proposed method was verified by using reachability graph.The research could provide decision-making support for the service busi-ness process optimization of complex equipment.%为了理顺复杂装备服务业务流程中各参与元素及其在流程中的位置和作用，提出了一种基于 Petri 网的复杂装备服务全生命周期业务流程建模方法：对复杂装备服务全生命周期进行了时间区间界定和服务业务的服务初期、中期、后期三阶段划分，通过分析服务业务通用构成要素，给出基于 Petri 网的业务活动逻辑发生关系模型和建模步骤。以某矿石类制造企业的大型立磨复杂装备建模为例，通过可达标识图验证了方法的正确性。本方法能为复杂装备服务业务过程优化提供决策支持。
