Operations Researcher
Uses mathematical modeling to optimize complex systems — airline scheduling, supply chains, hospital staffing.
Did you know?
In WWII, operations researchers found that setting depth charges to explode at 25 feet instead of 100 raised the share of attacked U-boats sunk from 1% to 7%.
How subjects help
- Mathematics: Build models that find the shortest delivery routes for a fleet of vans.
- Computer Science: Program solvers that test millions of timetables to find the best one.
- Economics: Weigh costs and benefits to decide how many staff or trucks a business needs.
- Statistics: Predict busy times from past data so hospitals have enough nurses on shift.
A famous name
George Dantzig: Invented the simplex method in 1947, the core tool operations researchers use to optimise plans.
Try it yourself: Run a mini survey
- Ask one clear question with a few choices, like "Which fruit do you like best?"
- Tally the answers as you go.
- Draw a bar chart of the results.
- Write one thing the data shows, and one thing it can't tell you (would a different group answer differently?).
Data scientists and statisticians ask good questions, count carefully and are honest about what the data can't show.
