A Novel Modeling Method of the Crowdsourcing Design Process for Complex Products-Based an Object-Oriented Petri Net

Abstract

Crowdsourcing design for complex products has open objectives and requires collaboration among different fields. It is difficult to use a single approach to describe the process in which the number and interaction of tasks and steps of tasks are changed dynamically depending on the execution state. Motivated by modeling the collaborative business process of crowdsourcing design in complex products, a crowdsourcing hierarchical process modeling approach based on an object-oriented Petri net is proposed. From the perspective of organization and task, the crowdsourcing object interaction and design process are modeled separately. First, an organization layer modeling approach based on expert review is proposed to describe the information transfer relationship among crowdsourcing objects from the organization perspective. Then, the task layer modeling approach based on the component decomposition idea is proposed. From the perspective of the task, the task is decomposed by using a design structure matrix (DSM) and a product structure tree to model the interaction of the design process. The object-oriented Petri net-is used to realize the representation of the model. Finally, the method is verified by taking the model of the crowdsourcing design of an air cooler as an example. The model subnet is analyzed by means of an overlay tree and incidence matrix, and the reliability and robustness of the model are proven. This method provides a reference for the process modeling of the crowdsourcing design of complex products.

Dynamic Synchronization Modeling and Simulation of Video Sensing Nodes Based on Internet of Things

“…The authors use the π network combined with the Petri net and the π calculus, establish the abstract model DSAM of the Internet of things video perception system, and realize the modeling of the dynamic synchronization of the IoT video perception system; being able to correctly handle the dynamic synchronization concurrency of IoT video perception has certain practical value [13].…”

Research on Modeling and Analysis of Logistics Business Process Based on Petri Net

“…This paper discusses the application of Petri net in business process modeling, including the representation of Petri net model in directed graph, how to establish a high-precision and reliable model, and how to deal with complex and concurrent business processes. Petri net model has many advantages for logistics business process modeling, among which the most obvious ones include accurate expression of concurrent operations, obvious relationship between before and after business process, easy understanding and analysis of graphics [13][14].…”

Supporting product lifecycle collaboration and knowledge-related evaluation: an active-passive collaboration mechanism and fuzzy evaluation method

“…Process modeling methods are focused on formal models [14]. Design structure matrix (DSM) based on the process architecture, possessing excellent computing capabilities, can analyze and optimize R&D process [15].…”
