PART II (Second, Third and Final Year)

MANAGEMENT SCIENCE

MSCI242L & 242M Spreadsheet Modelling for Management

This exam contains 3 sections. You must answer “ll of the questions in each section.

Section A contains 15 questions, and is worth 45 marks.

Section B contains 8 questions, and is worth 24 marks.

Section C contains 10 questions, and is worth 31 marks

Submission Rules

•   Deliverable is a completed Excel workbook uploaded to the exam Moodle, addressing all the questions

•   All answers must be presented in the correct answer cells on the Model sheet

•   The Model sheet should also include your ID number

•   All answers must be formula or function-based i.e. not simple/static values

•   Only correct results will receive the marks. No partial marks will be awarded

•   The model should not be password protected or contain links to external files

•   If you use a macro for Section C then you must include the macro in your file to get the marks

•   The model will be assessed on a University-spec. PC-version of Excel 2021

•   The model will be assessed using a sample of different SpecAd numbers, so all answers must be dynamic

Data Collection

All Excel datasets are held in a folder on the 242 exam Moodle called ‘Exam Datasets ’

The filenames are 3-digit code numbers, for example 123.xlsx

The file you must use is the one with the 3-digit code that corresponds to the LAST THREE DIGITS of your student ID number. For example, if your ID number is 12345678, then you should use 678.xlsx

All the datasets are different, sousing the incorrect dataset will generate incorrect results

Background

This task is based on a modified version of workshop 5 - Modelling Patient Flows.

However, this task differs from the original workshop version in four distinct ways.

1. The number of hospitals is four: Altnagelvin, Antrim, Belfast City and Causeway

2. The number of SpecAds is 100

3. The SpecAd list has been modified and is now listed in alphabetical order

4. The SpecAd costs have been updated with new values

Data Structure and Sheets

•   There are 6 sheets in the supplied dataset

•   Patient flow data for each of the four Hospitals, for all 100 SpecAds, is held on its own sheet, with the following names: Altnagelvin, Antrim, Belfast City, and Causeway

•   The SpecAd Costs sheet has the reference cost for each of the 100 SpecAds

•   The Model sheet is where you must submit all your answers, in the correct answer cells

Definitions:

Below shows an illustrative screenshot of the correct values for SpecAd number 2 (ANDC):

Note 1: Total episodes for each District are in cells H11:H38

Note 2: Total costs for each District arepresented in cells N11:N38

Section A

For this section, all answers must be formula-based, not static/pasted values.

You may insert intermediate formulas and calculations to the Model sheet but do not move any of the answer cells, or insert any rows or columns.

All questions in this section are worth 3 marks each.

Question 1

Using formulas, create the Summary Table (Episodes) shown on the previous page

The table must be dynamic and respond to a different SpecAd number being inputted in cell G2.

Question 2

Using formulas, create the Summary Table (Costs) shown on the previous page

Again, the table must be dynamic and respond to a different SpecAd number being inputted in cell G2. [Note: if any cell in the table produces any type of error, then return a blank cell instead]

Question 3

Insert a formula in cell G3 which returns the name of the SpecAd, based on the SpecAd number.

Question 4

Insert a formula in cell G3 which returns the SpecAd cost, based on the SpecAd number.

Question 5

[For example, for SpecAd number 2 this would be 5 episodes]

[Note 1: if there is atie for the highest number, then present the first hospital alphabetically] [Note 2: if all four hospitals have zero episodes, then return a blank cell]

Question 13

What is the smallest number of episodes at Belfast City hospital from any District (ignoring zeros), for any selected SpecAd?

[For example, for SpecAd number 2 this would be 2 episodes]

[Note: if all 28 Districts have zero episodes, then return a blank cell]

Question 14

What is the name of the District with the highest number of episodes at an individual hospital, for any selected SpecAd?

[For example, for SpecAd number 2 this would be Ballymena, with 4 episodes]

[Note 1: if there is atie for the highest number, then present the first District alphabetically] [Note 2: if all 28 Districts have zero episodes at all four hospitals, then return a blank cell]

Question 15

What is the name of the District with the lowest non-zero total episodes, for any selected SpecAd? [For example, for SpecAd number 2 this would be Antrim with 1 episode]

[Note 1: if there is atie for the lowest number, then present the first District alphabetically] [Note 2: if all 38 Districts have zero episodes, then return a blank cell]
