Module overview
The module has two parts. The first part provides an introduction to the topic of operational research (OR). The key role of using models in OR to obtain solutions of practical problems arising in a variety of contexts is emphasised. Some classical problems are analysed and standard techniques for solving them are investigated.
The second part of the module covers computer programming and its use in solving certain types of mathematical problems. The computer programming language used is Python.
