(4) The Design of A Software Agent Development Tool Student : Ding Hsin Huang. Adviser: Chyan-Goei Chung. Institute of Computer Science and Information Engineering College of Electrical Engineering and Computer Science Nation Chiao Tung University. Abstract Software agent is a program that has its own goal and execution thread. Software agent can act as a human-being that has the ability to work against any trouble and cooperate with other agents to achieve its goal. Software agent has four characteristics: autonomous, collaboration, learning human behaviors, and executing tasks anywhere in network by mobility. Therefore, software agent programs have been applied to developing large-scale multi-thread distributed system, such as data collection, network management, and network transaction. To accelerate the development of software agent-based system, there have been some development tools. However, these agent development tools just focused on coding level by providing agent classes to support user to write agent source code. There are no agent development tools to give an overall support from agent system analysis, agent behavior design, to agent system execution and validation. This thesis has design an agent system development tool that supports incremental development process and help user to analysis, design, and validate agent programs. At agent system design phase, our tool can support users to define agent system architecture, including the goal of agent, the tasks of agent, the relations between agents, mobility of agent, and learning ability of agent. At design and implementation phase, our tool will provide proper template code for user to apply. At validation phase, our tool supports user to define agent system deployment model and execute agent programs in order to validate the execution results. Our tool, which is based on IBM Aglets System, provides more services including architecture analysis tool and system validation tool. Users are able to increase agent system development performance and quality with our tool.. ii.
