Instrumentation design of n-linear sensor network

The authors investigate the problem of the structural observability. This work is based on a Groebner basis algorithm. The applicability of the algorithm is illustred by applying it on an example used by Bagajewicz. The first part gives an overview on Groebner bases. The second part develops the concept of observability bases and in the third part we show how to use these bases to make optimal the disponibility of the system by studying the reliability. Strategies for optimally locating sensors based on reliability and cost-minimization are developed.
