|Semester 1 Credit Value:||10|
To introduce students to multivariate statistical methodologies that allow them to analyse industrial data thereby realising an enhanced understanding of the process. The course covers three aspects in terms of focus – data pre-screening, feature extraction and process modelling.
This module addresses a real challenge that is of extreme relevance to the process industries. There are many cases where it is not possible to undertake experimental design and utilise the resulting data to attain enhanced process understanding, or the development of models for process monitoring or optimisation. The only data available may be that collected directly on the plant. Consequently it is not necessarily of an appropriate form, in the first instance, to execute the required task, be it finger printing or modelling. Therefore to extract the maximum amount of information, necessitates in the first instance the cleaning of the data (removing outliers, filtering the data, in-filling for missing data, time shifting variable, for example) prior to the application of appropriate statistical methodologies, such as principal component analysis if the objective is feature extraction. Multivariate statistical control of both continuous and batch industrial processes will be explored through the extension to principal component analyses. Additionally for process control and optimisation, it is essential to develop a robust model of the process of interest. The course introduces a number of linear modelling techniques to help realise the aforementioned objectives.

Teaching Rationale And Relationship
Lectures convey the statistical concepts and theory and their application in process engineering. Numerical practice sessions support the learning introduced in lectures through the students having the opportunity to apply the concepts to a number of problems varying in terms of complexity. The numerical practice sessions allow the completion of assignment work.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
Assignments allow engineering problems to be set and solved using computer software. They also provide the opportunity for the key skills listed above to be assessed and implemented.
