The abstract follows.
Hexaly Optimizer is a model-and-run mathematical optimization solver
that addresses a broad range of industrial optimization problems in the
areas of supply chain and workforce management, such as routing,
scheduling, packing, clustering, matching, assignment, or facility
location. Its mathematical formalism extends classical Mixed-Integer
Linear Programming with set, permutation and interval variables on which
any usual algebraic operator (arithmetic, logic, relational, etc.) can
be applied. Hexaly Optimizer is widely used in industry today, has
performances often comparable to the best dedicated algorithms, allows
compact modeling, scales well (with problem size and complexity) and is
constantly improving. This seminar focuses on the use of Hexaly
Optimizer to model and solve industrial scheduling problems. We show how
to exploit the mathematical concepts of the input formalism to model
several classic scheduling problems in an elegant and compact manner and
give an idea of the solver's performance compared to the state of the
art. Next, we outline the various techniques employed under the hood to
produce good-quality primal and dual solutions like constraint
propagation, local search, large neighborhood search, linear
relaxations, scheduling heuristics, or exact scheduling algorithms on
particular sub-problems.
The next talk in our series will be:
Norbert Trautmann (University of Bern) | December 4 | Mixed-integer
linear programming for project scheduling with resource-unit related
constraints
