CHNG3806: Risk Management for Chemical Engineering

Semester 2, 2022 [Normal day] - Remote

This unit of study aims to develop an appreciation of project and risk management practice of process systems for chemical and process engineering. It employs a holistic approach to management covering vital concepts in project management, technical risk assessment and decision making, economic evaluation and financial risk assessment, and project design optimization. It provides students with the experience and working knowledge to solve real world engineering problems in process-led and product-driven industries. By the end of this unit of study a student should be competent in: preparing a resume for use in employment applications; developing project work plans in conjunction with project management schedules; performing economic evaluations of projects, plans and processes; performing qualitative and quantitative risk assessments of projects, plans and processes; exploring optimization of complex processes under risk and uncertainty, covering unit operations, business units, enterprises and value chains.

Assessment summary

Assignments and Quizzes in this course are hurdle assessments which the passing mark is 60/100.

Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

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:

Unless prior approval is granted by the course coordinator/lecturers, late submission will attract 5% penalty of the full mark per day.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

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.

Attendance and class requirements

Students are expected to spend about 5 hours/week of independent/group study outside the specified contact periods.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.
