Research of Consistency Maintenance Mechanism in Real-Time Collaborative Multi-View Business Modeling

Real-time collaborative editing(RTCE)can support a group of people collaboratively work from distributed locations at the same time.However,consistency maintenance is one key challenge when different types of conflicts happen.Therefore a common synchronous mechanism is proposed to support consistency maintenance in the process of multi-view business modeling.Based on operation analysis on different views of models in the real-time collaborative editing system,detection of potential conflicts is realized by means of a decision-making tree.Then consistency maintenance provides a comprehensive and applicable conflicts detection and resolution for collaborative business modeling.Finally,a prototype of collaborative multi-view business modeling system is introduced to verify the approach.The point is that the mechanism proposes a comprehensive solution for collaborative multi-view business modeling.     

Semantic driven design reuse for 3D scene modeling

The increasing scale and complexity of 3D scene design work urge an efficient way to understand the design in multi-disciplinary team and exploit the experiences and underlying knowledge in previous works for reuse. However the previous researches lack of concerning on relationship maintaining and design reuse in knowledge level. We propose a novel semantic driven design reuse system, including a property computation algorithm that enables our system to compute the properties while modeling process to maintain the semantic consistency, and a vertex statics based algorithm that enables the system to recognize scene design pattern as universal semantic model for the same type of scenes. With the universal semantic model, the system conducts the modeling process of future design works by suggestions and constraints on operation. The proposed framework empowers the reuse of 3D scene design on both model level and knowledge level.
