Design strategies for industrial human-machine interface systems [for cement plants]

Computer technology is evolving very rapidly at the human-machine interface level. Most vendors are now offering Windows-NT based systems with advanced graphics and new capabilities. However, advanced technology by itself does not guarantee usability and relevance. Too often systems are designed by engineers or programmers with little contact with real-life operational conditions at the plant. A strategy is proposed to ensure that the system meets the real needs of its intended users, whether they be operators, maintainers, analysts or managers. Elements of this strategy have been used successfully in recent cement plant projects. Important cases are illustrated and explained. The results have been well received by the end-users of the systems.
