QBUS3330: Methods of Decision Analysis

Semester 2, 2026 [Normal day] - Camperdown/Darlington, Sydney

This introductory unit on decision analysis addresses the formal methods of decision making. These methods include measuring risk by subjective probabilities; growing decision trees; performing sensitivity analysis; using theoretical probability distributions; simulation of uncertain events; modelling risk attitudes; estimating the value of information; and combining quantitative and qualitative considerations. The primary goal of the unit is to demonstrate how to build models of real business situations that allow the decision maker to better understand the structure of decisions and to automate the decision process by using computer decision tools.

Assessment summary

  • Tutorial engagement: For at least 10 of the 13 tutorials submit to Canvas the assigned pre-work prior to class or in-class question/s during class AND attend class.  Marks are distributed equally for both requirements.
  • Assignment 1: Based on a number of different business scenarios, this assignment requires students to analyse the data provided, build appropriate models using the unit software “Precision Tree”, and then report on and discuss the modelling process, outcomes and any meaningful business inferences. 
  • Assignment 2: Focusses on building a simulation model for a business start-up, using the unit software “@Risk”. Students will be expected to report on and discuss model assumptions, inputs, outputs and business implications.
  • Mid-semester exam: This is a closed book exam covering concepts from weeks 1-6 of the unit. Questions will be short answer or extended response and may require students to build and interpret decision trees and undertake numerical analysis. Students will be expected to draw out of any analysis relevant business implications for decision makers.
  • Final exam: This is a closed book exam and can assess a student's understanding of any aspect of the unit from weeks 1-13. Questions could be short answer or extended response and will require students to build or interpret decision trees or simulation models as well as undertake numerical analysis. Students will be expected to draw out of any analysis relevant business implications for decision makers.

More detailed information for each assessment will be provided during the semester and shared on Canvas.

Use of generative artificial intelligence (AI)

You can use generative AI tools for open assessments. Restrictions on AI use apply to secure, supervised assessments used to confirm if students have met specific learning outcomes.

Refer to the assessment table above to see if AI is allowed, for assessments in this unit and check Canvas for full instructions on assessment tasks and AI use.

If you use AI, you must always acknowledge it. Misusing AI may lead to a breach of the Academic Integrity Policy.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

All assignments submitted after the due date will be penalised at the rate of 5% per day up to 50% in total as per Business School Guidelines.

Academic integrity

The University expects students to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

Our website provides information on academic integrity and the resources available to all students. This includes advice on how to avoid common breaches of academic integrity. Ensure that you have completed the Academic Honesty Education Module (AHEM) which is mandatory for all commencing coursework students

Penalties for serious breaches can significantly impact your studies and your career after graduation. It is important that you speak with your unit coordinator if you need help with completing assessments.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Support for students

The Support for Students Policy reflects the University’s commitment to supporting students in their academic journey and making the University safe for students. It is important that you read and understand this policy so that you are familiar with the range of support services available to you and understand how to engage with them.

The University uses email as its primary source of communication with students who need support under the Support for Students Policy. Make sure you check your University email regularly and respond to any communications received from the University.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. recognise the types of problems that decision analysis can and can’t address
  • LO2. develop the ability to identify the values, objectives, attributes, decisions, uncertainties, consequences, and trade-offs in a real decision problem
  • LO3. apply the concepts learned in this unit (expected value, value of information, risk aversion, and tradeoffs between attributes) to identify good decisions and strategies
  • LO4. demonstrate the ability to represent a decision problem graphically and/or mathematically
  • LO5. develop the skills to determine the optimal decision mathematically
  • LO6. cultivate the aptitude for identifying which parameters have the most impact on the results of an analysis
  • LO7. Develop the expertise of explaining the results of decision analysis to managers and other non-specialists.

This section outlines changes made to this unit following staff and student reviews.

To help obtain better learning outcomes from individual assignments, students will be required to report on and discuss in detail the modelling processes, outcomes and derived business inferences.

Public Holiday arrangements: The week 9 lecture and tutorials are on Monday 5th October, which is a public holiday. They will be rescheduled for later in the same week or in week 8 depending on timetabling constraints at the time.  Students will be advised as soon as timetabling changes are confirmed.
