Second Progress Report
of Progress :
have completed one and half year by the end of May 2000.
this project the following five classes of problems have been integrated
with the sole aim of linking them to industrial applications. The summaryof
these classes of problems is given as under. The details canbe seen in
the attached Technical Reports (IMG-TR) / Research Reports (IMG-RR) referred
to at the respective places.
Genetic Algorithms (GA's) and Economic Dispatch Problem.
survey on Genetic Algorithms has been completed. This includes some hybrid
algorithms alongwith Simulated Annealing. The CAI Lab of the Industrial
Mathematics Group now has a good glossary of Algorithms related to Gas.
These algorithms have been subsequently used for economic dispatch problems
posed as Travelling Salesman Problem and Bus Scheduling Problem. A comparative
study (on Bus Scheduling) between GAs and Classical Techniques has also
been undertaken. (IMG-TR-1999-2, IMG-TR-2000-1, M.Sc. Project 1999-05).
Dynamic Simulation by Differential Algebraic Equations (DAE's)
following developmental works have been undertaken.
of index in numerical solution to the system of DAE's.
a class of numerical methods say-- backward difference formula -- is applied
to the differential algebraic equations, it has been noted in the report
IMG-TR-1999-5 that the index of the problem is instrumental in amplifying
the truncation error (the amount by which the exact solution does not satisfy
the difference scheme) and the algebraic error due to early termination
of the iterative methods for solving the resulting system of nonlinear
algebraic equations. Further, it is observed that for higher index problems,
the algebraic variables can be categorized as index one, index two, index
three and higher index. Depending on the types of algebraic variables,
special scaling is needed in order to preserve the overall order of convergence.
of the existing software packages like DASSAL, RADAU etc. for solvingDAEs
numerically, requires the supply of index by the user. By adopting a Graph
Theoretic algorithm of Pantelides, which has been developed for consistent
initialization of DAE's, the index has been detected for a wide range of
problems in the report IMG-TR-1999-6.
mathematical model developed in (IMG-RR-1999-1, IMG-RR-1999-3) for an industrial
slurry high density polyethylene reactor gives rise to a class of discontinuous
dynamical systems consisting of DAE's. This problem which is worked out
in collaboration with NOCIL results in
supporting the prediction
analysis showing that the manipulation of pressure yields a faster change
in the reactor conditions as compared to manipulating the catalyst feed
of the model parameters
a literature survey on the tracking across discontinuties in dynamical
simulation problems has been carried out.
On-line Optimization: Algorithms and Implementations
Optimization involves networking of various modules. Each module requires
a thorough study of techniques used therein - Data Reconciliation, Parameter
Estimation and Error Detection.
theoretical study of these modules has been completed. Subsequently, two
robust algorithms - Generalized Reduced Gradient and SequentialQuadratic
Programming - have been tested on standard examples. They nowform part
of Resources generated under the Project. (Refer IMG-TR-2000-2, IMG-TR-2000-3,
Market Assessment and Forecasting Models
developmental work undertaken by the group for three different industries
Pfizer Ltd., Associated Cement Company Pvt. Ltd. (Thane), A.F. Fergusson
& Co., Mumbai resulted in
market conditions, evaluating existing brands and comparing with new brands
the relative positioning of all brands and change in the market mix
and forecasting market performance of the existing brands
survey on market segmentation

2000-01, 2000-02, 2000-03.
Computer Aided Geometric Design (CAGD) (Convexity Issues in Surface Designing).
of the main objectives of the DST sponsored project is to provide user
friendly software package on convex surfaces to the designer. The software
module developed by our group provides the Graphical User Interface(GUI)
to determine whether surface is convex. Graphical User Interface displays
the surface along with its Gaussian Curvature plot. If the Gaussian Curvature
plot goes below the X-Y plane along Z-axis, then the designer can safely
conclude that the surface is non-convex. The GUI uses freely available
public domain software package called `Geomview' to display the surfaces.
Then if the user wants, the module will search for the convex surface around
the given surface.The search algorithm used in the module is heuristic
group has also developed a software which can compute the surface interpolating
a given set of points, which makes designers job to provide the input for
the prospective surface extremely easy.
Software has been written in JAVA programming language. It provides applets
to the designer to give the control points of the surface and has control
over Geomview camera.The designer is also provided with the facility to
indicate the control points by just clicking on the Geomview camera. For
more details, see IMG-TR-1999-4.

& D Initiatives with Industry
a byproduct of this project, the group is also actively engaged in the
following Research and Development programmes with Indian Industries.
Density Polyethylene Reactor (Source of Problem; NOCIL)
from modeling and simulation, the group is presently working at a new research
and development problem on tracking discontinuities efficiently in DAE
modeled by the HDPE (see, IMG-RR-1999-02 and IMG-RR-1999-02).
Polymerization (with Hindustan Lever Limited)
polymerization is a process of great industrial importance which is used
for manufacture of latex paints, adhesives, coating, binders in papers,
textile products and synthetic rubber. The mathematical model gives rise
to a system of nonlinear ODE, integro-differential equations and single
first order nonlinear hyperbolic integro-differential equation. The group
has been working on a numerical simulator for the last one and half years.
Apart from computational issues, this class of problems gives rise to some
interesting theoretical questions related to convergence of numerical schemes,
existence and uniqueness results for large time. More importantly, the
question of asymptotic behaviour remains a challenge in the field of analysis,
(refer B. Tech. project Report 2000-01 and M.Sc. project report 2000-06).
and Control of a Crystal Size Distribution in an Industrial Crystallizer
(interested Industry: HCL,Foxboro in Chennai)} The first part of the project
involves modeling the system. This yields a mathematical model consisting
of a first order hyperbolic PDE (population balance of the crystal size
distribution) coupled through its boundary condition with an ODE (mass
balance of concentration) to which a control can be applied. Solving the
PDE yields a nonlinear hereditary system for which standard control theory
can be applied. The output quality (shape of the crystal size distribution)
and yield (volume of crystals produced) depends strongly on the concentration
evolution, see IMG-TR-2000-7.
general case (which is nonlinear and where the control is to yield a concentration
which is optimal over a range of time, instead of at some fixed time which
is the usual case) is not yet documented in literature from a control point
of view, refer to IMG-TR-(in preparation).
Optimization : Algorithms and Implementation
has been observed that in Error Detection Module, one can use Neural Network
Algorithms in conjunction with Genetic Algorithm to obtain faster and more
accurate convergence. It is perceived that this approach will lead to some
interesting problems involving differential equations, optimization and
numerical analysis--culminating to new modular development techniques pertaining
to On-Line Optimization.
main focus is on the Numerical Simulation of Option Pricing Models and
validating it using data from Indian Financial Markets. By adopting the
existing models to compute the volatility (roughly the market trend), some
experiments were conducted on the data obtained from some Indian companies
and the option pricing using Black -Scholes Model has been computed with
the help of finite difference schemes. For more details, see, M.Sc. project
concerns with the problem of scheduling a fleet of buses to a given set
of trips encountered by BEST in Mumbai. As a preliminary step, a single
depot vehicle scheduling problem has been formulated as Zero One integer
linear programming problem and is solved using primal-dual algorithm. The
model is tested on real world data obtained from BEST. For details, see,
Research with Academic Institutes
with Foreign Universities
Mohan C Joshi visited University of Kaiserslautern, Germany and University
of Twente, Netherlands during May-June, 1999 to explore the possibility
of collaborative research programmes between IMG, Bombay and these universities.
Both institutions are receptive to the idea of collaborative programmes
and efforts are on progress to come up with a joint programme.
may be mentioned that University of Kaiserslautern has a very strong group
on Industrial Mathematics and is one of the core universities among European
Consortium on Mathematics for Industry ( ECMI). A linkage with ECMI will
not only help IMG in generating solutions for industry based problems but
might also lead to new academic programmes involving both institutions-IIT
Bombay and ECMI Universities.
