Goalnet: Intelligence in Workflow Orchestration Zhiqi Shen Nanyang Technological University June, 2007
Background • Web services support interoperable machine to machine interaction over the internet; • Workflows describe tasks and execution procedures; • Business process modeling; and • System integration.
Challenges • Web services are not always available; • Web service needs to be selected dynamically; • Many workflows available defined using different tools; • Process execution path is decided on the runtime; and • Decision making is required.
Our Solution • Goal oriented modeling; • Decision making on goals and actions; • User interaction; • Agent mediation and monitoring; • Goal Net modeling tool • Process modeling • Agent modeling
Intelligence for Decision Making • Process modeling • Web service/workflow orchestration • Goal selection and action selection • Multiple decision making mechanisms support • User interaction
Agent based System • Agent system generation • Development platform available • Goal Net Designer • Agent Creator • Goal Net Loader
Workflow/Web Service Orchestration • Tasks in transitions • Workflows • Web services • Functions • Services selected by agents during runtime • Execution path (goal pursuit) is decided at the runtime
Proposed Architecture for The Bio-Manufacturing Domain Grid/web services Grid/web services
Bio-Manufacturing Grid Objective is to reduce time from biomedical research to mass production of diagnostic kits. • The system integrates workflows and supply chain processes using the Grid • Collection, storage and tracking of bio-samples • Sequencing of the genomes of samples • Design and Fabrication of DNA chips to test samples • Analysis of results • Making cost effective diagnostic kits via genes identified
