A mathematical model can be very simple or very complex. The goal is to represent a system or process using precise definitions and mathematical relationships. One way to create a model is to simply start building it, acknowledging it won't be perfect, but trying to improve the model along the way. Eventually you should arrive at a basic (fairly simple) model, which you can then make more complex (and perhaps more accurate) by elaborating in areas that previously were glossed over.
For instance, if I want to represent amount of daylight in a single day, one of the simplest models might be:
- For any given day D, some percentage of that day occurs in which there is measurable daylight L.
However, I can improve this model and make it more complicated by:
- Measuring daylight L as hours, minutes, seconds, milliseconds (or similarly as some percentage up to a particular decimal point e.g. 49.255%) of some day.
- Adding new variables, such as a geolocation--G1 longitude and G2 latitude, since daylight is a function of where on the earth measurement is taken. Or, allowing daylight to be more than a percentage, represented by an additional variable for luminosity U (imagine clouds reducing the impact of daylight).
However, perhaps some of the complications are not relevant given the context, so one may want to simplify the model to simply be:
- Daylight L for any given day D is a function of location only (G1 longitude and G2 latitude). Now, if we construct a look-up table for daylight at any given geolocation, we'd be able to find L(G1, G2) = some # of seconds per day D.
Voting systems Model
There are three sections to this model: variables (our basic definitions), relationships (attempts to represent a more complex understanding of the components of our model), and the side-line (items that will complicate the model further, to be tackled later, as we go).
Overall questioning the "1 person, 1 vote" assumption in an effort to assess fairness and error in voting systems.
Variables
- Va = a voting event.
- E = overall error
- e = error
- T = a topic to be voted upon
- b = a single ballot
- v = a vote (a choice)
- J = jurisdiction (a geographic boundary)
- M = a vote counting method
- t = tabulation time
Relationships
- For any voting event Va, there exists an overall error EVa.
- For any voting event Va, there exists at least one jurisdiction J.
- For any jurisdiction J, there exists an error eJ.
- For any jurisdiction J, there exists at least one vote-counting method M.
- For any jurisdiction J, there exists n number of ballots b1, ..., bn.
- For any jurisdiction J, there exists an average time to tabulate an individual ballot tM1, ..., tMn.
- For any ballot b, there exists some number m of voting topics, T1, ..., Tm.
- For any ballot b, there exist vT1, ... vTm votes, each of which can be null (no vote).
- For any ballot b, there exists a corresponding method Mx
- For any ballot b, there exists a ballot type y.
Side-line
- Rank-choice? -- Other voting styles, multiple votes per voter
- Anecdotal secrete ballot
- Some voters may require assistance (potential introduction to error?)
- Vote-counting is functional
- What about predictions?
- Errors on basis of discernable intent of the registered voter.
- We are not concerned with human intermediaries (e.g. volunteers).
