DCSs aim to centralize plant operations to allow control, monitoring, and reporting of individual components and processes at a single location. A short summary of this paper. With agents, maintaining the overall system is easier because instead of changes occurring to a colossal program, changes take place on a small scale without disrupting overall operations. Based on study of the multi-Agent technology and electric system structure characteristics, the paper presents the layered software architecture of electric system and implementation model. We've developed a set of tools and methodologies to help design, build, test, and verify such systems.

A short summary of this paper. This book describes how control of distributed systems can be advanced by an integration of control, communication, and computation. The approach that is used takes advantage of distributed artificial intelligence at the planning and control levels to achieve significantly shorter up-front commissioning times as well as significantly more responsiveness to change. Furthermore, according to the difficulty to debug of the communication protocol in actual electric system, the proposed Agent communication model can be used for decreasing the working capacity to maintain the system's communication protocols, and the results show that the model enhances the system's adaptability and stability. room one or two diesels are used for driving the propellers and in ship Computer Science Distributed Ebook - Notes - Lecture Notes- Distributed System Syllabus covered in the ebooks Unit–I Characterization of Distributed Systems: Introduction, Examples of distributed Systems, Resource sharing and the Web Challenges.
