The store is comparing two ordering policies: (1) Order up to 3 units every
3 days if the stock level is less than 2, else do not order. (2) Order 3 units if the
stock level is zero, else do not order. The fixed ordering cost per shipment is $200.
Immediate delivery is expected.
Which policy should the store adopt to minimize the total expected daily
cost of ordering?
You are driving your new taxi cab at the highway. Suddenly, an ambulance speeds off your way at 100km/hr. counter flowing from the usual path and is 30 meters away from you. You glanced at your speedometer and found out your instantaneous speed is 60 km/hr. You must react quickly at split-second to avoid accident. What could be the best thing to do?
