The cost of a particular pavement is given by:   b C T  aT , where C(T) is the cost per land-mile of paving, T is the thickness of paving applied (in inches), a is the cost of laying one inch of pavement over one line-mile, and b is an economies-of-scale parameter (b < 1 if there are economies of scale). The pavement deteriorates so that each 0.2-inch of paving extends roadway life for another year. If a = $500,000, b = 0.72, and the discount rate is 5%: 1) How thick should the pavement be laid

Jimmy's delicatessen sells large tins of tom tucker's toffee. the deli uses a periodic review system, checking inventory levels every 88 days, at which time an order is placed for more tins. order lead time is 22 days. daily demand is a constant 1515 tins, so average demand during the reorder period and order lead time (1010 days) is 150150 tins. draw a sawtooth diagram. assume that the beginning inventory level is equal to the restocking level and the desired service level is 99.9%. what is the safety stock level? (hint: look at the formula for calculating restocking level.) what is the average inventory level? the safety stock level is average inventory level is __chart: time (10,20,30), tins (0,150) lines touching both axisthe safety stock level is 0 tinsthe average inventory level is 75 tins
