The daily demand of a dairy product a local retail store is believed to be constant and deterministic at 100 units. However, once ordered for replenishment, the lead time varies and follows normal distribution with an average of 7 days, and a standard deviation of 1.5 days. If firm only accepts 1 percent stockout probability, then what should be the reorder point? Round-up to the nearest integer O a. 827 O b. 947 Oc. None is correct O d. 893 1049
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
