Objectives

The objective of this research project is to investigate the development of object oriented design frameworks using design patterns

Research Tasks

The current research Activities include:

• Designing a framework for closed-loop control systems using an existing set of design patterns. The patterns used in the frame work have been tested and used in many other applications. The utilization of the patterns and their interconnection to produce a generic architecture for a feedback control system is the main target of the proposed framework.

  • A design framework for feedback control appliactions has been developed

   

• Design and development of application specific frameworks for real-time software system and  distributed system applications.  Reusable patterns are deployed in the proposed frameworks.   Analysis and design patterns shall be used in different phases of analysis and design of the framework.   An architecture based on layered structure for distributed applications shall be developed.   Investigation will be conducted on using  Design Patterns in suitable layers in this layered architecture.    A distributed health care system will be used as an illustrative example.   Health systems standards will be used to guide the development of the framework.

  • We are investigating a developement methodology to built framework using design patterns as their building blocks which we called Pattern Oriented Frameworks

   

• Abstraction of new design patterns used and produced in the real-time distributed application frameworks.  New design patterns shall be investigated when required in the framework desgin. Currently we have documented:

  • A set of Finite State Machine patterns

  • A pattern language of statecharts

   

• Developing specification for building frameworks for large scale systems using design patterns.  The objective is to define the interconnection relationship between patterns to develop frameworks in an easy and fast manner.
