Optimal Design of Multivariate Alarm Systems

This chapter is about the optimal design of multivariate alarm systemsAlarm systemmultivariate. The essence of designing multivariate alarm systems is to exploit some features of multiple related process variables to distinguish normal and abnormal conditions. The features are diverse, being general for many industrial processes or being specific for particular industrial devices. First, two general methods are presented to respectively exploit normal operating zones and variation directions of multiple variables as the features being applicable to many industrial processes. Second, two specific methods are provided for two types of industrial devices, electrical pumps and condensers, based on their own unique features. Numerical and industrial examples are presented to illustrate the proposed methods.
