Abstract

This paper focuses on optimal sensor allocation in Distributed Sensor Networks (DSN) for complex systems which are represented by Bayesian network (BN) models. The paper presents a new strategy to transfer the optimal sensor allocation problem into a set-covering optimization problem. Furthermore, the efficiency of the search algorithm is improved by integration of BN models and the greedy search algorithm. Case studies on two manufacturing processes are conducted, which demonstrates the effectiveness of the proposed method in abnormality detection.
