USIPLEX
University of SIegen
SimPLEX Education Software
USIPLEX was developed at the department of Management
Information Science to help students understanding the Simplex
algorithm including the primal and dual Simplex algorithm, the
Big M method and aspects of duality.
Ensuring an optimal learning success, USIPLEX provides
different modes to encourage the user to learn in an active
way. First of all, each algorithm is explained using generated
or own exercises from the user at which detailed information
can be shown (for the more interested students). USIPLEX wants
to cover both experts and beginners therefore the explanations
can be chosen as simple and intuitive or in a mathematical way.
It is also possible to prohibit or allow special cases during
the algorithms which guarantees the adaptability to the needs
of the user. After understanding an algorithm, the software can
test the skills of the user in the practice mode. Here it is up
to the students to type in the correct solutions, the system
only checks and criticizes if the entries are wrong.
A problem (containing two structure variables) can be displayed
as a graphic to show the backgrounds of the algorithms and
maybe how to solve a problem graphically.
USIPLEX insists mathematical precision. To ensure this,
fractions are implemented and (if desired) displayed. This
arranges for the ability to provide all rational numbers.
