AI EDAM is a journal intended to reach two audiences: engineers and designers who see AI technologies as powerful means for solving difficult engineering problems; and researchers in AI and computer science who are interested in applications of AI and in the theoretical issues that arise from such applications. The journal publishes original articles that develop new and interesting applications based on the most up-to-date research in all branches and phases of engineering including analysis synthesis and design; manufacturing and assembly; and concurrent engineering. Specifically the journal is interested in the use of AI in planning design analysis simulation spatial reasoning and graphics manufacturing assembly process planning scheduling numerical analysis optimization distributed system and multi-agent applications. AI EDAM is also interested in original and serious applications of state-of-the-art knowledge-based techniques to important engineering problems (termed practicum papers). In addition to the rapid publication and dissemination of unsolicited research papers AI EDAM is committed to producing issues on topics that are viewed as both important and timely. Special issues for 1999 include Temporal Logic in Engineering and Generative Systems in Design. AI EDAM is indexed in Compendex Plus SciSearch Research Alert and CompuMath Citation Index.
