A hospital orders its blood from a regional blood bank. Each year, the hospital uses an average of 1,400 pints of Type O blood. Each order placed with the regional blood bank incurs a cost of $30. The lead time for each order is one week. It costs the hospital $25 to hold 1 pint of blood in inventory for a year. The per-pint stock-out cost is estimated to be $55. Annual demand for Type O blood is normally distributed, with a standard deviation of 43.26 pints. Determine the optimal order quantity, reorder point, and safety stock level. Assume that one year is 52 weeks and that all demand is backlogged.
