79299 - Design of Experiments

Course Unit Page

Academic Year 2018/2019

Learning outcomes

The course objective is to learn how to plan, design and conduct experiments efficiently and effectively, and analyze the resulting data to obtain objective conclusions. Both design and statistical analysis issues are discussed. Particular attention will be paid to: understanding the process of designing an experiment including factorial and fractional factorial designs; examining how a factorial design allows cost reduction, increases efficiency of experimentation, and reveals the essential nature of a process.

Teaching methods

Lectures and computer exercises with Excel and R.

Assessment methods

The assessment aims to evaluate the achievement of the following learning objectives:

  • the knowledge of the design of experiments methodology

  • the ability to design factorial experiments in practical cases

The exam is written, and it contains 3 or 4 exercises to complete in two hours.

During the exam it is not allowed to consult textbooks or notes.

The evaluation is expressed as a grade of out of 30.
