Three Software utilize OR’s models to solve problem
first .
examples of OR applications:
• designing the layout of a factory for efficient flow of materials
• constructing a telecommunications network at low cost while still guaranteeing QoS (quality of service) or QoE (Quality of Experience) if particular connections become very busy or get damaged
• road traffic management and ‘one way’ street allocations i.e. allocation problems.
• determining the routes of school buses (or city buses) so that as few buses are needed as possible
• designing the layout of a computer chip to reduce manufacturing time (therefore reducing cost)
• managing the flow of raw materials and products in a supply chain based on uncertain demand for the finished products
• efficient messaging and customer response tactics

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.
examples of OR applications
•efficient messaging and customer response tactics
•roboticizing or automating human-driven operations processes
•globalizing operations processes in order to take advantage of cheaper materials, labor, land or other productivity inputs
•managing freight transportation and delivery systems (Examples: LTL Shipping, intermodal freight transport)
•scheduling
