A modeling approach for Cyber-Physical Systems based on collaborative processes
Full text linkBased on the Industry 4.0 initiative, this paper presents a modeling approach for Cyber-Physical Systems (CPS) that is based on collaborative processes. The approach is called MA4.0 (Modeling Approach 4.0) and is made up of four kinds of models: the system model, the collaboration models, the component models, and the process models. The system model shows the types of the components of the system and their relationships. The components may be devices and software systems. The relationships denote collaboraboration models that consist of message-driven interactions and control blocks. Component models show the structure of components: software systems are made up of internal processes while devices also include operating units. Processes are event-driven and leverage the data flow instead of the control flow. The approach is illustrated with the example of a manufacturing cell
People-oriented Enterprise Information Systems
No full textCurrent notations and languages do not emphasize the participation of users in business processes and consider them essentially as service providers. Moreover, they follow a centralized approach as all the interactions originate from or end in a business process; direct interactions between users cannot be represented. What is missing from this approach is that human work is cooperative and cooperation takes place through structured interactions called conversations; the notion of conversation is at the center of the language/action perspective. However, the problem of effectively integrating conversations and business processes is still open and this chapter proposes a notation called POBPN (People-Oriented Business Process Notation) and a perspective, referred to as conversation-oriented perspective, for its solutio
Data-awareness in B2B process modeling
Full text linkThis paper presents a notation to model business processes in the context of B2B (Business to Business) systems. Data-awareness is a key asset of the notation: data is placed at the forefront of process representations and task execution is data-driven instead of control-driven. In addition to process models, the notation (B2BPN) includes three other types of models, i.e. the architectural model, the collaboration models and the information model of the process. Data can transit between B2B processes through the interactions defined in the collaboration models and such models represent the relationships between the companies taking part in B2B systems. The notation is illustrated with an example concerning the order management of a distributor
The representation of human choices in business process models
Full text linkTasks and artifacts are recognized as first-class citizens in business processes but there is still no consensus on how to represent them. This paper proposes a notation, named ENTA, which allows both task-centric models and artifact-centric ones to be defined. The major contribution is the emphasis placed on human-centric processes and, in particular, on the choices under the responsibility of the participants. The consequences are a strong connection between tasks and business entities and the introduction of structures of work encompassing all the tasks that have some common input entities. An example related to an order handling business process is used to present the major features of the notatio
