摘 要：This chapter addresses the problem of selecting optimal observation points for scanning networks in view of a combinatorial optimization approach. In the existing formulations, an optimal sensor activation schedule is computed as that which globally minimizes a criterion directly connected with the expected quality of the parameter estimates. But then the key difficulty becomes the large scale of the resulting global optimization problem, since the monitoring networks encountered in process industry or environmental engineering may often consist of several hundreds of stations. Obviously, this makes the exhaustive search on a candidate-by-candidate basis practically intractable and creates a need for techniques which would implement guided search and have acceptable performance.
