Optimal sensor placement is one of the important methods for optimal design of mechatronic BIT system.Effective detection is the important constrain for optimal sensor placement.In fact the reliability of sensors must be considered while optimal designing the system because it would influence the effectiveness of system.Analyzed the detectable model
a mixed integer nonlinear programming (MINLP) model is proposed for optimal placement of sensors in this article.MINLP is based on detectable model of fault mode of equipment and sensors of BIT system.The objects of optimization are minimization of failure probability and cost of selected sensors.The constraints of this model involves the influence of failure probability of sensors on the FIR
FDR and FAR of mechatronic BIT systems.The solution can provide a optimal scheme for sensor placement.MINLP is applied to a detection system for a Servo system and its practicability is analyzed.
