Use the following to answer the following 5 questions. A firm sells a product with an annual demand of A=6000. The holding cost is CH=$2 per unit per year and the ordering cost is CP=$50 per order. The shortage cost is Cs=$10 per unit. Demand exhibits some variability and management has estimated that lead-time demand follows a normal distribution with a mean of 300 and standard deviation of 40. What is the reorder point if management wants a 50% probability of satisfying demand in any given cycle? If the criteria for reordering is changed to: Allow, on average, 1 cycle with a stockout per 20 cycles, what is the reorder point? Suppose management sets the reorder point to R=350 units (and Q=500 units), what is the resulting service level (fill rate)? plz answer fast thanks!!! will upvote
