Abstract
Optimal sensor placement is the basis of equipment health management.Considering the influence of sensors reliability on health management
a model of optimal sensor placement is presented.The objects of optimization are cost of selected sensors and minimal harm of undetectable faults
and the constraints conditions are the detection capacity indexes.Since the optimal placement of sensors is a multi-objective mixed integer non-linear programming model
a solution method based on extended particle swarm optimization is proposed.The application shows the model and the solution are effective.
