                    SUMMARY OF PROFESSIONAL

                                  EXPERIENCE



Teaching

        Over 21 years‟ experience in teaching mathematically based courses stressing
both the pure theoretical basis of the subjects being taught and the application into
practice, such as Optimization Methods, Operation Research, Quantitative Methods in
Economics, Nonlinear Automatic Control Systems and Data Processing.



Significant Scientific Contributions

         Developed an original numerical method for computer-aided solving of nonlinear
systems of equations by temporarily increasing the dimensonality of the problem instead
of decreasing which is usual. In this way the obstacles encountered in n-dimensional
space are avoided. The effect could be compared to a plane flying freely in the air while
only its two-dimensional shadow suffers a lot of obstacles on its way.

          Extensive numerical investigations of the new method and other well-known
global optimization methods were carried out and the efficiency of the method has been
tested using multiexternal test functions as Rastrigin, Goldstine-Price, Branin, Hartman
(for n=3 and 6) and Sheckel (for n=5.7.10). Numerical results were published and
presented at several international symposiums, showing high accuracy and applicability
in cases where other existing methods have failed. The main advantages of the method
appear to be its independence of the nonlinear function type being analyzed and on the
initial estimation for the solution, which make the method applicable in difficult-to-solve
nonlinear global optimization problems.
Mathematical Models for Business and Industry Application

         Developed mathematical models and software for different optimization and
statistical analysis problems in electrical and civil engineering practices as well as in bio-
cybernetics, chemical engineering, and economics, such as:

Problem of determining the distribution of active and reactive powers in electric circuits;

Civil and mechanical engineering problems in the strength of material             where
nonlinearity occurs out of the profile loaded, as well as out of the nonlinearity of the
deformation itself;

Chemical engineering problem of determining all relevant thermodynamic parameters in
carbon-dioxide explosions;

 Bio-cybernetics problem connected with the Otto Francs Elastic Reservoir Theory
studying the chemo dynamic irregularities of the arterial part of the cardiovascular
system, with some characteristic parameters of   the heart model involved.

Operation Research problems such as determination of the optimal moment of a machine
or a spare part exchange by application of dynamic programming and other methods;

Calculation of different trajectories in oscillatory systems represented in a form of
integro-differential equations through their discrete analogue;

Statistical analysis problems in medicine and production processes in industry.

Games based on some interesting ancient mathematical problems such as four-color
problem.

         An overview, tracing the three-stage development of ideas and experience in
interactive computer-assisted methodologies for investigation of multi-input multi-output
technological systems and their large-scale interconnections is presented. The discussion
evolves around the basic idea of a real world object, conceptual and mathematical
models, information and control in technological systems. It begins with brief
presentation of inter-related concepts of system, information and control and of the
concept of complexity. The concept of complexity and its attributes of dimensionality,
information constraints and system uncertainties are recalled. Then certain aspects of
large-scale systems theory, systems engineering and decentralized control as related to
the impact on interactive computer-assisted methodologies is also given. The discission
proceeds further with the experience gained in developing and using such methodologies
for multivariable and large-scale control systems with and without nonlinear phenomena.
A summary on the structure of software engineering of such computer-assisted
methodologies is given along with it. Current and future research developments are
indicated.

         A new approach and procedure is developed belonging to the area of continuos
methods, for solving a set of arbitrary nonlinear equations. Themethod is based on a
movement along the ridgepath of solution curve in the n+1 dimensional space. The
reliability of the method is demonstrated on a problem of determining the power flows
and voltages in an electrical power method is its independance of the nonlinear function‟s
type being analised and of the initial estimation for the solution. Also, this method is
recommended for locating the solution in the extremely complex cases, using the reached
results as an initial estimation for application of some other faster method.

         Determining the exact moment of exchanging a machine or a spare part is a
problem which is very often encountered in engineering practice. In the paper a
mathematical model of a system is developed containing transcedent functions. Systems
of this kind are very difficult to treat with most of the existing methods. In the paper a
computer-aided method which solves such systems succesfully is presented and the
numerical results are given. Grafic presentation of the model is also provided as well as
the listing of the programs developed.

THE NEW METHODS FOR SOLVING ARBITRARY MULTIVARIABLE

        A new method for solving nonlinear static models, belonging to the area of
continuous methods, has been developed and presented. In the paper a new approach and
a new procedure is suggested which allows moving along the solution curve ( or
ridgepath) in either direction when it is vertical, sppiral has an extremely steep slope or
changes its direction to the opposite one, and no regular finite step application method
could solve the problem when independent variable increment approaches infinity.



      Extensive numerical investigations have been carried out and the reliability of the
method illustrated on a problem difficult to handle with othwr existing methods.

       In the paper a very witty and original algorithm for moving along a solution curve
which occurs in the new-developed method for nonlinear global opptimization always in
accordance with its slightest slope is developed. The algorithm is based on the

CONTROL SYSTEMS WITH SLIDING MODES”, Proc. of the 6-th Yugoslav
Symposium for Applied Robotics and Flexible Automation, Novi Sad (Yu), p.p. 137-144,
1989.



        Decentralized multivariable (MIMO) variable-structure control systems based on
linearized arbitrary state-space model with assigned switching hyperplanes are studied in
the prospect of flexible automation. The controller desighn takes into consideration
reachability and sliding conditions, checks the stability of the sliding motion and
investigates the robustness of the design to parameter variations and disturbances through
simulation and use of a qudratic performance criterion. The problems are ameliorated by
decomposing the model into single-input single-output (SISO) subsytems and applying
decentralized control techniques. An example is included making direct comparizon
between the MIMO and decentralized approaches.

IFAC/IFORS/IMACS Simposium “Large Scale Systems: Theory and Applications”,
Berlin, Germany, August 29-31,1989, vol.1,p.p. 55-58.



         This paper presents a computer assisted method for solving arbitrary sets of
nonlinear static equations, as well as the application of this method to problems of power
distribution, explosion parameters of carbon-hydrogen composition and parts
replacements time optimization. The method is based on a new approach of movement
along a solution curve in the extended ( (n+1) dimensional space. It has been applied to a
number of nonlinear static problems known as difficult to solve, as are the three cases of
different applications included in this paper. The main advantage of this method is its
independence of the type of nonlinear functions in the model. It is also independent of
the initial solution estimation, provided its rough range in the definition domain is known
in a broad sence. It has the property of converging to the solution sought even in the most
complicated cases where other methods do not work.

        Important segments of the optimal economic dispetch problem are optimal load
allocation, operation planning and expansion planning are given. A fast, direct
calculation method is presented using derived analytical formulae that can be applied to
complex hydro-thermo-pump electric energy systems. An optimization technique for
nonlinear cost function, subject to equality and nonequality constraints is used to
compute the control strategy as a sequence of power command vectors to coordinate the
electricity generation plants in the system over the time period of interest. Results for an

desicion-making in large scale computerized systems for supervision, control and
management of complex technological objects are to become indispencible. They have to
be based on both Artificial Intelligence (AI) and System Engineering (SE) techniques.
There has been designed and implemented with us an AI computer, called ESTIO and
aimed at process behaviour recognition and typical identification using certain classes of
well-posed models in the role of a knowledge-base. It has been used for identification
purposes by people with basic knowledge in systems and control, and no knowledge in

Simposium for Electronics, Telecommunication, Automatics and Informatics, ETAI „89,

        In systems science and engineering applications, as well as in economics and
applied mathematics, it is not at all unexpected for a nonlinear system to occur which is
very often difficult or impossible to handle with existing methods.



      In the paper a procedure for solving this type of problems based on the idea of
movement along a solution curve in the (n+1) dimensional space is presented and
computer assisted.



        A new approach and procedure is proposed for an automatic following of the
solution curve occuring in our method, in any direction of extension, steep up, vertical
and spiral, or even for following the curve reversing its direction. if the solution curve is
spiral one, no regular finite step application will solve the problem near the region where
the slope approaches infinity.
       The adventages of our method, being its independence of the nonlinear function‟s
type and independence of the initial estimation, in this way is fully used.

is accepted, and results for an optimal inventory for three different coefficients of the

FREQUENCY ASSIGNMENT”, Symp. on Operations Research SYM-OP-IS 90‟,
Kupari, Yugoslavia, Oct. 12-15 1990.



        The problem of frequency and channel assignement is treated via graph network
modelling and coloring of nodes in this model. The graph structure itself represents the
available difuse spacing of a set of radio and TV frequencies/channels, respetively, as
well as their possible over-lappings. Regular graph coloring by using minimal number of
different colors coresponds to the number of different channels, the frequency gap among
which is big enough to avoid signal interference. Our research with respect to this
problem of frequency and channel assignement has resulted in an efficient algorithm for
soloring general graphs which resolves this problem known as NP-complete problem.
This algorithm operates through determining and deleting subsets of graph nodes which
may be monochromatically colored without color overlaping due to reducing the average
interconnectivity in the graph. By successive application of the algorithm on the newly
derived graphs in this way and their chromatic number determining, enables regular
coloring of the basic graph structure, that is, optimized non-overlapping frequency and
channel assignement.

“MODELLING, SIMULATION AND CONTROL OF FMS-LIKE SYSTEMS VIA
PETRI-NET FORMALISM”, Theoretical Researh in Natural and Technical Sciences in
SRM, Macedonian Academy of Sciences and Arts, Skopje, June 1990.



       In this paper a computer-aided approach to the modelling, simulation and control
of discrete-event FMS-like systems by using Petri-net mathematical formalism is
presented. This approach is particularly effective when based on time-placed Petri-nets.
Their possibilities for adequate modelling of various concurent and conflict situations,
synchronizations and quatitive time-analysis have been appeared to be convenient in
simulation of event-related control. An example of simulated complex FMS-like system,
subsystems of which enter interactions quated, which events scheduled servicing by
means of private and shared resources, is given as an illustration.

IMPLEMENTATION”. Theoretical Research in Natural and Technical Sciences in SRM,
Macedonian Academy in Sciences and Arts, Skopje, June 1990.



         In automatics and system egineering and in other technical sciences and
applications, as well as in economics and applied mathematics, it is not at all unexpected
a nonlinear system to occur which is very difficult or impossible to solve with existing
methods. In the present paper a new computer-aided method for solving this type of
problems, based on the idea of dimensional euclidean space is presented. A new approach
and ptocedure are proposed for automatic following of the solution curve in arbitrary
propagation direction or when it is propagating vertically and spirally or reversing its
direction, cases which are extremely difficult to handle. If the solution curve is a spiral
one, no regular finite step procedure will solve the problem near a region where the slope
approaches infinity. The adventages of our method, above all its independence of
nonlinear functions‟ types and independence of the initial estimation, this way are fully
instrumental. The theoretical foundations of the method are presented in the first part of
this paper, while the computer implementation is presented in the second part.
Concluding section is given in the second part of the paper.
