M. cotteleer electronics supplies microcomputer circuitry to a company that incorporates microprocessors into refrigerators and other home appliances. one of the components has an annual demand of 250 units, and this is constant throughout the year. carrying cost is estimated to be $1 per unit per year, and the ordering (setup) cost is $20 per order. the company operates 250 days per year. to minimize cost, how many units should be ordered each time an order is placed? how many orders per year are needed with the optimal policy? how many days in between orders what is the average inventory if costs are minimized? suppose that the ordering (setup) cost is not $20, and cotteleer has been ordering 150 units each time an order is placed. for this order policy (of q = 150) to be optimal, determine what the ordering (setup) cost would have to be. $

1. alwaysrain irrigation, inc. would like to determine capacity requirements for the next four years. currently, two production lines are in place for making bronze and plastic sprinklers. three types of sprinklers are available in both bronze and plastic: 90-degree nozzle sprinklers, 180-degree nozzle sprinklers, and 360-degree nozzle sprinklers. management has forecast demand for the next four years as follows: both production lines can produce all the different types of nozzles. the bronze machines needed for the bronze sprinklers require two operators and can produce up to 12,000 sprinklers. the plastic injection molding machine needed for the plastic sprinklers requires four operators and can produce up to 200,000 sprinklers. three bronze machines and only one injection molding machine are available. what are the capacity requirements for the next four years? (assume that there is no learning.)
