In this time of New Year resolutions I will post re solutions. ;)*
In mathematics the solution is the answer.
- Theta is 57 degrees.
- The price has increased by 15%.
In statistics a solution provides something we can be reasonably sure of.
- We are 95% confident that the price of a house increases by between $5,000 and $7,000 for each extra bathroom, all other things being equal.
- The margin of error is 3 percent.
- There is evidence that more men prefer milk chocolate than dark chocolate.
What is called a solution in operations research could be called an alternative, which is not necessarily optimal, practical or even feasible. There can be infinite solutions. Finding a solution is a step towards solving the problem. We do great things in The Science of Better, but a solution is only a start.
- We should order flour every 2.3 days.
- There should be five servers operating.
- A possible location for the hospital is in a new satellite town.
In all disciplines teachers need to make the language of the discipline clear.
Students need to watch for the specialised use of language in a discipline. Assuming you know what a term means, because it is a familiar term, can cause confusion.
* The OR blog challenge for January was OR Resolutions. This is the best I could think of. It’s our summer holidays here.
