Smart Machine Supervisory System: Concept, Definition and Application

In today’s competitive world, manufacturers have realized that they need to embrace automation as their mantra to success. However, the impact of automation primarily concerns with the effectiveness of process monitoring and control systems. There is a need for a closed loop supervisory system, which integrates and coordinates individual process modules for real-time adjustment, conflict resolution and priority assignment. Monitoring and control of multiple process modules will result in higher productivity, better quality and prognostics for near-zero breakdown performance.
In this paper, we define the supervisory system as open architecture system that integrates and coordinates individual process monitoring and control modules such that a real-time globally optimal machining solution is delivered for maximum productivity. The Smart Machine Platform Initiative (SMPI) is currently being managed by TechSolve in support with Coalition on Manufacturing Technology Infrastructure. SMPI efforts at TechSolve concentrate on six thrust areas including the supervisory system. We then proceed to explain the technical and functional requirements, benefits and architectural details with emphasis on the knowledge system. A prototype supervisory system application is explained with objectives, setup, technologies identified and results.
We conclude with further insights into issues and implications for successful realization of a smart machine supervisory system.
