چکیده

this paper presents an optimal integrated instrumentation sensor network design methodology for complex nonlinear chemical process plants using a combinatorial particle swarm optimiazation (cpso) engine. no comprehensive sensor network design approach has been addressed yet in the literature to simultaneously incorporate cost, precision and reliability requirements for nonlinear plants. the presented approach attempts to accomplish this objective via enhancement of the estimation accuracy of the aimed instrumentation sensor network subject to desired cost, reliability and redundancy constraints. an unscented kalman filter (ukf)-based data reconciliation algorithm has been developed to present evaluating measures through comparisions of the estimated and real variables in terms of modified root mean squared of error (mrmse), while cpso maintains the provisions of the network fault tolerence (nft) including sensor netowrk reilability (r), strong and weak redundancy degrees (i.e., srd and wrd). the developed cpso engine searches in a diverse variety of possible sensor networks to adopt the most fitted one based on the imposed nft and cost design constraints. the effective capabilities of the proposed design methodology has been illustrated in a simulated nonlinear continuous stirred tank reactor (cstr) as a complex process plant benchmark.

Design of Nonlinear Sensor Networks for Process Plants

In this article we extend and generalize the ideas of two previous articles devoted to linear sensor networks to nonlinear systems. In those previous articles the use of cutsets and a decomposition procedure were proposed and proved efficient to solve large scale linear problems. In this article we show that a similar procedure, now based on a variable elimination scheme, can be also used effic...

A New Cost-Optimal and Fault-Tolerant Instrumentation Sensor Network Design Methodology for Chemical Plants

In this paper, an optimal redundant instrumentation sensor network design methodology is presented for complex chemical process plants using a combinatorial particle swarm optimization search (CPSO) engine. The approach, which is more flexible and general in comparison with previous works, aims to minimize cost as a main design factor, similar to the usual trend in the literature. Besides, it c...

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, w...

Wireless sensor network design through genetic algorithm

In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...

A Comprehensive SoC Design Methodology for Nanometer Design Challenges

SoC design methodologies are under constant revision due to adoption of fast shrinking process technologies at nanometer levels. Nanometer process geometries exhibit new complex design challenges in silicon which were not seen in higher geometries. The most commonly talked about factor is the dominance of interconnects over cell delays for long nets. Also leakage power at sub-nanometer levels i...
