BIG DATA ANALYTICS
ASSIGNMENT
Date Set: 29 March 2021
Date Due: 19 April 2021
2 of 7
Introduction
In this Big Data Analytics Assignment, you will be assessed in two areas: theory and practice.
In the theory area, we expect you to critique recent publications in the big data analytics
domain. In the practice area, we present you with datasets on which we expect you to perform
appropriate analysis and draw managerial conclusions. Each of these areas will comprise 45%
of your marks. As is the case in many other assignments, 10% of the marks are attributable
to style and presentation.
The word limit for this assignment is 1,500. It is an upper limit, not a target. Please report the
number of words and do not exceed this limit (this includes references). Although theory
and practice questions are equally weighted, we anticipate you will use more words in the
theory part, roughly 2/3 of your upper limit.
Please use the discussion board for any questions you might have about this assignment. We
will answer all questions that are asked on or before 15 April 2021 -12 pm to minimise the lastminute
stress and encourage timely attention to the assignment.
It has been an absolute pleasure to teach you big data analytics. We hope you enjoy this
assignment and use the techniques in the future.

Q1 Theory [45 marks]
Identify three recent academic papers- two on predictive analytics and one on prescriptive
analytics within logistics and supply chain problem context.
Critically discuss the application of predictive and prescriptive analytical techniques
for improving supply chain performance.
Using your favourite research database (e.g. Scopus), search and select three papers that
explain the application of different predictive and prescriptive analytical techniques to solve
logistics/supply chain problem. Please do not use a literature review paper in your selection.
We are looking for applied research papers. Don’t forget to include selected three papers in
the list of references. Please highlight them separately (in bold) to other references that you
may use.
Q2 Practice [45 marks]
For the practical part of the assignment, we have prepared datasets for you to replicate the
analyses we have done in the module to a larger extent. For this purpose, we have an affinity
analysis exercise, where we have done some of the preprocessing on the company’s data to
assist you. Affinity analysis helps us determine which products are likely to be ordered
together. It relies on the number of occurrences of instances and presents a confidence score
for the likelihood of two products being bought together to inform warehouse layout decisions
(e.g. using the output of your analysis, the manager may decide to put the products bought
together in closeby locations to reduce the picking time). The confidence score is the number
of instances Product 1 and Product 2 were bought together over total instances Product 1 was
bought. Product 1 in this case is the first product mentioned in the rule.
In the “affinity_data_and_product_names.zip” file, you will find two text files:
1. affinity_data.txt
2. affinity_productnames.txt
“affinity_data.txt” has the orders placed with a company over a four-month period in 2019.
Each row indicates an order and each column is the products held in stock by the company.
The data is made of 0s and 1s where 1 indicates that the product was in the given order. This
data file comprises 67844 orders of 21447 products, so it will take a while to load to memory
depending on your computer.
4 of 7
“affinity_productnames.txt” has the names of the products that you will need to use when
reporting your findings.
Please report the descriptive statistics for the number of products in an order (min, Q1,
median, Q3, max, mean, standard deviation). Please note that we are asking for the
descriptive statistics of one variable: the number of products in an order, which you will have
to calculate before you produce the descriptive statistics.
Please perform an affinity analysis exercise on this data to draw the top five rules with the
highest support for the occurrence of two products together. In your response, we expect
you to present the support and the confidence in the rule with the corresponding product
names.
Please add your script as an appendix with appropriate comments.
Style and Presentation [10 marks]
You will receive marks for the style and presentation of your assignment. Please pay
attention to
1. Writing grammatically correctly and concisely.
2. Providing captions for your tables and figures and citing them in the text.
3. Using an appropriate level of accuracy (no need for 5+ figures after the decimal
point. We recommend 3).
4. Presenting your assignment in a report structure, so we can map your answers to the
questions we have asked.
5. Citing the references you used in preparing your answers.
Marking Criteria
Marks will be awarded for the level of understanding demonstrated in the concepts and accuracy of your answers.
