• SOR2002 Statistical Inference (Sem 2)

Pre-requisite: SOR1020 & SOR1021

Lecturer: Dr L McFetridge

Introduction

The course builds upon the probability theory in SOR1001 and the statistical inference methods in SOR1002 to provide a second-level account of the principles and most important methods of estimation and hypothesis testing.

An important element of this module will be a weekly practical data analysis lab using the SAS software package. SAS is probably the leading statistical package used in industry. The lab sessions, approximately 2 hours long, will give students an opportunity to put the theory of lectures into practice. During the lab sessions students will be guided through practical tutorials on reading, accessing and editing data in SAS, descriptive statistical analyses, cross tabulations, graphs, charts, frequency tables, χ² tests, t-tests and analysis of variance tests. Some of the lab time will also be allocated for project work.

The practical work in the lab sessions culminates in a group project. During the semester the student will work as a team member on a specific statistical investigation using the methods described in lectures and performed in the SAS lab sessions. This provides a valuable insight into the applications of statistics in industry allowing students to gain the necessary skills required for such a working environment. Near completion of the group project, each group will be required to give an oral presentation (approximately 5 mins per student) on the results of their analysis. This provides an opportunity for the group to receive feedback on their progress and helps consolidate their findings before submitting a final written report on their investigation.

• SOR2003 Methods of Operational Research (Sem 1)

Pre-requisite: SOR1020 & SOR1021

Lecturer: Dr S Moutari

Introduction

This course applies mathematical analysis to a series of problems which occur in business and industry. The analysis can be more far reaching if we use a deterministic model but a degree of uncertainty (e.g. about future events) is often an important feature of the situation and a stochastic model has to be used. The statistical knowledge assumed is that contained in SOR1001. Although novel ways of setting out the work may be used in some topics, the mathematical techniques required on this course are no more advanced than simple calculus and algebra and most practical problems require only arithmetic and the use of tables.

The aim of the course is to teach a range of simple techniques illustrating the application of mathematics and probability theory to the problems of business and industry. Apart from the first two chapters each chapter is a distinct and separate topic. Some topics (e.g., Forecasting) involve lengthy calculation and students are taught how to use a spreadsheet for the computation. Students who do not have access to a spreadsheet on a personal computer can use the Open Access Areas. Specific instructions on the use of the Excel spreadsheet is given on the course and there is a practical session in an Open Access Area.

Homeworks are an essential part of the learning process, but there is no continuous assessment.

Emphasis is placed on choosing the correct model for the circumstances and on presenting answers in a form intelligible to management. If a question is posed in words then the final answer should be in words and not left in algebra or in a table. The practical problems associated with obtaining data are discussed. The answer should be to a number of significant figures consistent with the accuracy of the original data, or rounded to an integer if that is appropriate.

Content

• Deterministic inventory including quantity discounts, common cycle production, constrained inventory and the use of Lagrange multipliers.
• Stochastic inventory models including service levels.
• Simple and adaptive forecasting.
• The use of spreadsheets and their application to forecasting and equipment replacement.
• The replacement of deteriorating equipment and the replacement of equipment liable to sudden failure.
• Acceptance sampling by attribute and variable.
• Network planning including PERT, speeding up, the use of LP, Gantt charts and resource smoothing.
• Decision analysis including utility curves, decision trees and Bayesian statistics.
