Mathematical Programming is the title given to a collection of optimisation algorithms that deal with constrained optimisation problems. Here the problems considered will all involve constraints which are linear, and for which the objective function to be maximised or minimised is also linear. These problems are not continuously differentiable; special algorithms have to be developed. The module considers not only the solution of such problems but also the important area of post-optimality analysis; i.e. given the solution can one answer questions about the effect of small changes in the parameters of the problem (such as values of the cost coefficients)?
There are no prerequisites for this module.
No other modules have this module as a prerequisite.
- Graphical techniques
- The Simplex Method
- Artificial variables, the M-Method and the two-phase Method
- The dual simplex Method
- Integer Programming and piece-wise linear programming
- Elementary post-optimality analysis
- To develop the mathematical skills that will provide you with the appropriate foundations for further mathematical studies in Operations Research.
- To enable you to analyse OR problems that may arise in your future employment.
