Research And Implementation Of Task-oriented Process Modeling Language And Visual Modeling Tool

With the rapid development and popularization of Internet, how to share andintegrate different kinds of resources in the open, dynamic and difficult-controllingnetwork environment has become a major challenge, and people pay more and moreattention to the business process modeling technique, which can make the independentservice resources achieve seamless integration to improve interoperability andreusability. Business process modeling technique is responsible for representingbusiness process, which is the important foundation of the process restructuring andanalysis. The process modeling language is the core and basis of business processmodeling technique. It normatively defines the interaction and executing logic betweenservices in business process.Task-oriented process modeling combines different simple and abstract services tocertain complicated service that can provide more powerful business function accordingto certain process logical. Then, through configuration, the services will be binding tosome specific capabilities so as to realize the task customization and process reuse,providing personalized service and responsing to the changing environment timely.This research presents TPML（Task-oriented Process Modeling Language）, anddesigns the visual process modeling tool based on TPML. Combining the scriptlanguage and metadata control technique, TPML can be applied to the business processintegration flexibly and efficiently in specific areas. The visual process modeling toolcan realize the task customization and process reuse by modeling and configuration.Finally, the author use a simulation system to demonstrate the feasibility and scalabilityof TPML and that the visual process modeling tool can support the task customizationand process reuse.
