NUS Exam Results (MSc)

4 years ago I shared my NUS exam results for my bachelor's degree in Mechanical Engineering. Today I'll be sharing all my exam results in the graduate program of Master of Science (Industrial & Systems Engineering), specializing in Operations Research (OR).

Semester 1: AY2015/2016 Semester 2

Module	Description	MCs	Grade	Remarks
IE5002	Applied Engineering Statistics	4	A-	Foundation module
IE5003	Cost Analysis and Engineering Economy	4	A-	Foundation module

SAP: 4.50
CAP: 4.50

Semester 2: AY2016/2017 Semester 1

Module	Description	MCs	Grade	Remarks
IE5001	Operations Planning and Control I	4	A	Foundation module
IE5004	Engineering Probability and Simulation	4	B+	Foundation module
IE5203	Decision Analysis	4	A-	Elective module for OR

SAP: 4.50
CAP: 4.50

Semester 3: AY2016/2017 Semester 2

Module	Description	MCs	Grade	Remarks
IE5107	Material Flow Systems	4	A-	Elective module for OR
IE5108	Facility Layout and Location	4	A	Elective module for OR
IE5205	Healthcare Systems and Analytics	4	A-	Elective module

SAP: 4.83
CAP: 4.56

Semester 4: AY2017/2018 Semester 1

Module	Description	MCs	Grade	Remarks
IE5123	Reliability Engineering	4	B+	Elective module for OR
IE5504	Systems Modelling and Advanced Simulation	4	A+	Elective module for OR

SAP: 4.50
Final CAP: 4.55

CAP: Cumulative average point
SAP: Semestral average point

The requirements for MSc (ISE) are not complicated:
4 ISE foundation modules + 6 ISE elective modules.

For my case, in order to specialize in Operations Research (OR), 5 out of of the 6 elective modules have to be those that are counted towards specialization fulfillment (see remarks).

All the best to those who are planning to get enrolled in this program.

Module Review: IE5002 - Applied Engineering Statistics

Semester	AY2015/2016 Semester 2
Program	Master of Science (Industrial & Systems Engineering)
Module Code	IE5002
Module Title	Applied Engineering Statistics
Modular Credit	4 MCs
Teaching Staff	Prof Goh Thong Ngee

This is one of the four foundation modules for the master's program, and it's kinda known as the killer module because who knows applied statistics can be so scary and hard core.

If Prof Goh is still the lecturer for this module when you're reading it, good luck. His notes comprise of a pretty generic collection of statistical analysis, and a lot of self-exploratory work may be expected, like reading up some of the books recommended in this module.

In the first lecture, it was outlined by Prof Goh that statistical analysis branches into:

• Descriptive statistics
• Inferential statistics
• Mathematical statistics

and the focus of this module revolves around inferential statistics.

Student's t-test

Hypothesis testing, something that was rather new to me, was introduced, and by hand, we were taught how to perform Student's t-test (one-sample, two-sample, paired etc) at the start. Just remember the null hypothesis H₀ always states that one mean equals another mean or a value.

Analysis of Variance

Analysis of variance (ANOVA) to me it's like t-test with more than two treatments, and to test if significant difference prevails across treatments. You'll need to understand how to read and analyze an ANOVA table (this part is not difficult).

Design of Experiments

Design of experiments (DOE), wow, what should I say, this is probably the hardest topic in the module. You need to be able to estimate the factor effect, perform statistical testing, and analyze the residual etc. 2^k factorial design and alias structure of the design are something you need to familiarize yourself with before you call yourself prepared for the exam.

Study Tips

Go through all the tutorial/assignment questions and understand how he arrives at the solutions. Of course statistical software like Minitab is able to compute the results quickly and conveniently but the down-to-earth way of computing should be comprehended.
And since the exam is open-book, writing down the steps of arriving at each solution will be beneficial not only when you need to refer during the exam, but also when you need to get yourself familiarized with the concepts.

Exam

Open-book exam, but that doesn't mean that you should study less.
Guess what was the very first question I got during my semester of study, it goes like this:
You are teaching applied engineering statistics to a class at Ngee Ann Polytechnic, which book would you use to teach? Indicate the year, author and publisher etc of the book.
Epic right, never have I come across such stun.

I got an A- for this module.
