Integrated System for Supervision, Control, and Economic
Optimization of Industrial Processes
What is SISCO?
is an information system for the supervision, control, and optimization
of industrial processes. It was intended to support the operators in the
supervision, control, and management of an industrial plant. The main feature
of SISCO is that allows to manage the plant
since an economic point of view. In this way, SISCO
not only considers technical parameters but also incorporates economic
indexes such as costs and benefits.
SISCO shows to the operators an integrated
view of the whole automation system. This facilitates the supervision and
control of the plant.
SISCO allows to consider economic indexes
in the operation of a plant, which indicates the real economic impact of
the control actions.
SISCO facilitates the control of the production,
given information about the costs and benefits of the plant operation.
SISCO calculates in real time economic
indexes such as costs, incomes, and economic benefits.
SISCO estimates the behavior of the most
important technical and economic variables of a plant, using models that
SISCO optimizes the global operation of
a plant since an economic point of view, and considering the operational
SISCO is highly flexible and it can be
configured according to the characteristics of each process.
SISCO has 3 main modes of operation:
Evaluation, Consult, and Optimization.
The Evaluation mode gives on-line information
about economic indexes of the process. For instance the cost of production
and the incomes due to the transference of products.
The Consulting mode uses predictive models
to estimate variations in the technical and economic variables with respect
to the change of a manipulated variable. Also, the Consulting mode indicates
if a change of a manipulated variable violates technical restrictions,
such as the limits of the main variables.
SISCO was developed over SCAUT-3G for windows NT. We are currently working
in new versions for other operative systems.
The Optimization mode is based on models
that allows to determine the optimal control strategies in order to maximize
an economic objective function. This function considers the main variables
of a plant and the technical restrictions.
Case of Study
The evaluation of SISCO in a real grinding plant shows that
the objective function presents a large variability. This is due to the
fact that higher benefits can be reached with a large feeding to the mills,
but this produces saturation of mills or hydrocyclons which forces to reduce
A conservative estimation indicates that the reduction of this variability
in only 5% can increase the benefits as much as 3%. In this way, for a
plant with a production of 50,000 Tons/day is possible to recover the investment
in less than one month.
