Integrated Process Sensor Network Design

Hitherto, instrumentation network design methodologies have been based solely upon sensor capital costs. Within this framework the cost of new instrumentation is minimized subject to constraints indicating the desired level of performance. While, these formulations account for the cost of a network, they do not reflect the potential benefit of adding sensors. To capture this potential profit, we have developed a new formulation of the instrumentation design and upgrade problem based on the expected trade off between value and cost (for additional details concerning material accounting see Bagajewicz et al. (2004), for control systems see Peng and Chmielewski (2004b) and for fault detection see Narasimhan and Rengaswamy (2004)). In this work, we aim to combine the three, profit based sensor network design formulations into a single integrated sensor network design.
