Scheduling concerns the allocation of limited resources to tasks over time and is pervasive and important in the management of industrial and government organizations. For the last two decades, interactive scheduling systems have become one of the most effective and efficient tools for real life scheduling applications. Due to the advent of information technology and client/server technology, design and development of scheduling systems with interactive support on the Internet will be one of the innovative approaches to tackle sophisticated scheduling problems. In this paper, we describe the structure of a prototype scheduling system. Then we propose a new approach to design and development of an interactive scheduling system on for the Internet users. We also present an architecture of intelligent agent to support interactive and cooperative scheduling systems on the Internet. The conclusion is discussed in the last section.
