Section D 2020

Section D of your Unit 1 exam will focus on the skeleton program and improvements to it. The question will specify which part of the program is to be used, and what you need to change. I will create a list of potential improvements, and over time we code each one and document it.


Adding Functionality

One of the things to notice is that the option menu misses out number 5. So this will be something to add to the skeleton program. This could be to:

2020 - Save a running simulation

2020 - Process multiple days in one go, ie process a week

2020 - Create a subclass for SmallSettlement

Simple Improvements

You may get some simple questions which are often adding validation of some kind:

2020 - Validation on entering text instead of numerical values

2020 - Validation for entering a numerical value in a range

2020 - Validation for ensuring values can't be negative (eg fuel cost)

You may get some questions to add extra outputs to the user:

2020 - Ensure costs are displayed in the format £X.XX

2020 - Display how many days have passed

2020 - Display net gain/loss for the companies

2020 - Display net and average weekly gains/losses for individual outlets

Standard Improvements

You may also get questions which might involve extending a current feature such as events:

2020 - Add a new event called food scandal, this causes the reputation to fall 20 points

2020 - Add a new event called weather disaster, this will cause the cost to rise by 20 percent for all companies

2020 - Brexit will increase fuel costs by 30% and other costs by 25%

2020 - Brexit will half the probabilities of households eating out

Other extended features could be:

2020 - Households essentially use the closest outlet, make it so the outlet must be within a distance of 20

2020 - Currently no use is made of GetCapacity, make it so an outlet can only have this number of visitor in day

2020 - The probability of eating out is lower on a monday, and high on a friday, saturday & sunday (eg days MOD 7)

2020 - Allow outlets to expand by increasing the max capacity

2020 - Option 5 is missing, it could be to remove a company

2020 - Option 5 is missing, it could be to merge 2 companies

2020 - Companies can keep running even though they have a large negative balance, allow companies to go bankrupt and stop trading

2020 - Allow a company to relocate an outlet for a cost

2020 - Add extra categories for example 'Gastro Pub' and 'Fine Dining'
