If lead-time demand shows variability that follows a normal distribution with a mean μ =420 and a standard deviation σ =20, what will the revised reorder point if two stock-outs (shortages) are allowed?
What is the company’s reorder point if the probability of a stock-out on any cycle is restricted to 0.05?
