  11. examples of OR applications

    • 1. HOW A FRENCH GUY CAN TEACH IN A MANDARIN-SPEAKING COUNTRYProblem: I speak French, you speak Mandarin.Solutions:+ English+ Images+ Stupid questions (I do not ask stupid questions because of stupidity, its just for checking that theres no misunderstanding)+ Interrupt me + send emails+ Feel free of discussing in Mandarin
    • 2. I dont want so speak Chinese to youIn France, we say “this is Chinese to me”for “I cant catch a word”.==> Please tell me if I “speak Chinese to you”.
    • 3. DISCLAIMERFact 1: Many applications in these lessons are about military applications.Reason: Easy to understand + many precursor operation research works are military.Fact 2: My main application fields are ecological and energetical.Implication: We will see such applications later, with much more details.
    • 4. WHAT IS THE POINT IN THESE 3 HOURS ?This is about Operations Research (OR).Key points: – OR can help a company/country to save up plenty of $. – new OR works usually do not originate at the head of companies / countries; originate in young people who want to do new things. – you can be very useful if you understand the goal of OR.
    • 5. Operations Research everywhere. I hope that from now on, you will see plentyof OR opportunities everywhere.
