| Research Abstract |
The research aims to establish methods for design high reliable object oriented software, those for describing the systems, and those for deriving efficient program codes.
First, we focused on Petri-nets and its extended models. We have proposed a method deriving workflow from a given Petri-net model extended with clocks as a color of a token. The method also provides a flexible schedule management system for the derived work-flow.
We have also proposed a synthesis method for scenario based GUI specification. The scenario is based on timed automata model.
Next, we have proposed a method to derive program codes for personal appliances automatically from Petri-net based specification, which efficiently works on a resource limited personal appliance. Its execution scheme sends needed codes from a server by on-demand-scheme.
Last, we have proposed a method to develop real-time distributed systems form UML/OCL specification. It is based on component-based design and to exploit the hierarchical design, it can efficiently verify timeliness QoS. The proposed method also automatically derives control codes in Java form the specification.
