MATH1058 Operational Research I and Mathematical Computing

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. One of the pre-requisites for MATH2013

Aims and Objectives

Module Aims

For the operational research (OR) part of the module, the aim is to provide an insight into the usefulness of some OR techniques for solving various decision-making problems. This is illustrated by introducing some optimization problems, describing OR techniques for solving them, and giving practical examples of situations where these problems arise.
