Assignment Two: A spreadsheet-based decision model
Background
This is an individual assignment. The modelling work should be submitted online in the Assignment Folder as a single MS Excel file with the required information in clearly labelled separate worksheets. In addition, you are also required to submit a report that summarises your models and results. Your report must be in MS Word file format. Any other file format, such as pdf, is NOT acceptable and will not be marked. In summary, two files should be submitted – one MS Excel spreadsheet and one MS Word file.
The assignment has six sections:
1. Model description, conceptual model, and assumptions
2. Spreadsheet-based decision model
3. Scenario analysis
4. Spreadsheet-based stochastic decision model including justification for the choice of distribution 5. Simulated distribution for each output and a risk analysis
6. Report.
The requirements of each section are detailed below. The breakdown of marks (total is 30) is given in the Assignment 2 Rubric at the end of this document.

Assignment Details:
You are required to develop a spreadsheet-based decision model that can be used to investigate and explore decisions and risks relating to taking a business loan (e.g. for investment) for a small-to-medium sized business. The model needs to be generic enough to enable the decision maker to explore the size of the loan that is viable/manageable within different scenarios of income, cost, expenses, loan amount, deposit made on the loan, repayment amount, other financial commitments, the amount of interest paid etc. and understand the risks associated with meeting the loan commitments.
The decision model must be realistic and easy to use. The level of complexity modelled, for example the choice of deterministic vs. stochastic inputs, input distributions, etc., is left to your discretion. However, the model must enable the user to input the following business cost/expenses and loan details/options.
• Utilities (Electricity& Gas &Water)
• Telephone/mobile
• Insurance
• Maintenance
• Paid salaries
• Other
No data is provided. You are required to create a fictitious business and demonstrate the utility of the decision model using real data where available (e.g. interest rates) and create data where it is not (e.g. income, business expenses).
Note that Net Profit = Sales revenue – Total variable costs – Fixed costs – Overheads.
The minimum requirements of the decision model are:
1. Ability to enter loan details, income, costs, and expenses to explore decision options relating to the loan amount and repayments to calculate outputs such as total interest paid and duration of loan.
2. Ability to understand the impact of variation to the loan interest rate, income, costs, and expenses over the duration of the loan.
3. Stochastic treatment of some of the inputs to explore resulting simulated output and summarize risks.
Your submission will be assessed across these six sections for a total unit mark of 30%:
Section 1: Model description, conceptual model, and assumptions (File: MS Word; 5 marks)
• Provide a brief overview of the model
• Include a conceptual model
• Note any relevant assumptions.
Section 2: Spreadsheet-based decision model (Files: MS Word & Excel; 5 marks)
Design a spreadsheet-based decision model. All cells displaying fixed inputs, stochastic inputs, decision variables, calculated variables and output variables.
Section 3: Scenario analysis (Files: MS Word & Excel; 5 marks)
This section relates to Topic 7. Use Excel’s scenario analysis and investigate the impact that different scenarios for each stochastic input on the outputs. The choice of best and worst scenarios is yours.
Section 4: Stochastic variables including justification for the choice of distribution (Files: MS Word & Excel; 5 marks)
This section relates to Topic 8. This will require you to justify your choice of distribution for each of the stochastic inputs.
Section 5: Simulated output distribution and a risk analysis (Files: MS Word & Excel; 5 marks)
This section relates to Topic 9. This requires you to examine the simulated distributions for each output, and undertake a risk analysis based on simulation modelling, in order to quantify the risks associated with problem.
Section 6: Report (File: MS Word; 5 marks) Word limit: No more than 1500
The report should be a standalone document. It should include:
1. A brief description of the model (maximum 100 words) 2. The conceptual model and any assumptions behind the model.
3. The decision model copied from the spreadsheet.
4. The best- and worst-case scenarios chosen, and a discussion of the consequences.
5. Justification for the choice of probability distribution.
6. Risk analysis report based on the simulation modelling.
