In several process plants the precision of parameter estimates is low because the installed set of instruments do not satisfy the new information requirements for different purposes, from simple data reconciliation to on-line optimization. This paper presents models to perform the upgrading of instrumentation at minimum cost to achieve maximum precision of selected parameters. Alternative equiv...

In this paper, an extension of previous work performed for a system of two plants is presented. For a set of n plants, heat transfer leading effectively to energy savings occurs at temperature levels between the pinch points of supplying and receiving plants. In some cases, additional heat transfer in other regions is required to attain maximum savings. A systematic procedure, based on LP and M...

In this paper, we propose a set based approach for detecting faults in input/output channels of a closed-loop multivariable system. This approach works with deterministic bounds on measurement noises, disturbances, and fault signals, which may be attractive in some applications. The fault detection problem is formulated as an optimization problem in the state space framework. The dimensionality...
