Our paint store (OPS) sells 5 different paints to consumers: Red, Yellow, Green, Brown, and Blue. Demand of each color paint is normally distributed with monthly mean (gallons) and standard deviation summarized in Table 1. Annual holding cost rate is 25%. Each order incurs an ordering setup (fix) cost of $1,000, and lead time is 2 months. Our paint store (OPS) wants the probability of stocking out (1-SL) to be no more than 5% (use z=1.65).
