A Review of Optimal Sensor Deployment to Diagnose Manufacturing Systems

Optimal sensor deployment is the foundation of an effective monitoring/diagnosis system design. Unfortunately, owing to the technical complexity, any issues related to optimal sensor deployment can deteriorate the performance of the sensor system, which has consequently received much attention and interest. This paper aimed to review the current literature studying optimal sensor deployment looking at modeling characteristics and strategy implementation. First, the modeling characteristics with four key elements, namely cause-effect model, optimization benchmark, optimization strategies, and performance assessment, are surveyed thoroughly. Second, a wide variety of strategy implementation of sensor deployment is discussed in detail. Finally, the open-ended issues faced by industry and academia are discussed and several principle conclusions drawn.
