So I had to compromise with operational research work, which had the intellectual challenge that interested me and the commercial value that was valued by the clients: things like scheduling freight trains, time-tabling buses, stock control, lots and lots of stock control.
Asa că am făcut un compromis apelând la resurse externe care se confruntau cu aceleaşi provocări intelectuale şi cu valoarea comercială importantă pentru clienţi: planificarea transportului de marfă, programul autobuzelor şi controlul stocurilor.
