Redundant sensor network design for linear processes

Abstract

Measurements of process variables have a considerable impact on

Sensor Selection and Optimization for Health Assessment of Aerospace Systems

“…This objective function was extended to include hardware redundancy (measuring a variable using more than one sensor) and spatial redundancy (more than one way of estimating a variable) (ref. 16). Within the graph theory algorithm, the sensor network can be optimized with respect to only a single criterion; therefore, this objective function was adapted for processing with genetic algorithms (ref.…”

Design of robust, reliable sensor networks using constraint programming

“…Even though reliabilities are functions of time, in the typical sensor network design literature (Ali & Narasimhan, 1993, 1995, 1996, constant values of reliabilities have been considered. The sensor network design problem then is: given (constant) sensor reliabilities, choose variables to be measured so as to maximize R. The given sensor reliabilities can be thought of as corresponding to an arbitrary time t. Scaling issues in reliability framework.…”

“…In the sensor network design literature, the concepts of reliability and network reliability were formalized in Ali and Narasimhan (1993). The concept of network reliability (Ali & Narasimhan, 1993, 1995, 1996 accounted for sensor failures and also indirectly incorporated the observability criterion. This work (Ali & Narasimhan, 1993, 1995, 1996 used a graph theory-based greedy search algorithm to obtain the most reliable sensor network.…”

This work (Ali & Narasimhan, 1993, 1995, 1996 used a graph theory-based greedy search algorithm to obtain the most reliable sensor network. A tree type enumeration procedure for the design of minimal cost network with constraints on precision, availability, resilience and error detectability was reported in Bagajewicz (1997).…”

“…While these have been considered in the literature mainly via enumeration or greedy search-based approaches (Ali & Narasimhan, 1993, 1995,1996Bagajewicz, 1997), we present an explicit constrained optimization formulation using the notion of cutsets. This results in a MINLP problem.…”
