4ZhengYang Wang ITEC S2 Final Presentation Introduction – Project Aims To develop a system, Simulator of Business Collaboration Reliability Verification (SBCRV) Model and manage business collaboration and provide verification methods for the collaboration reliability Model and manage business collaboration and provide verification methods for the collaboration reliability Choreographical Business Transaction Net (CoBTX-Net), a well defined verification model for business collaboration reliability. Choreographical Business Transaction Net (CoBTX-Net), a well defined verification model for business collaboration reliability. SBCRV provides visualisation of the formal model and it can be used as a tool for system analyst/developer of distributed information systems in a collaborative environment SBCRV provides visualisation of the formal model and it can be used as a tool for system analyst/developer of distributed information systems in a collaborative environment
