Atoy manufacturer makes its own wind-up motors, which are then put into its toys. while the toy manufacturing process is continuous, the motors are intermittent flow. data on the manufacture of the motors appears below.annual demand (d) = 50,000 units daily subassembly production rate = 1,000setup cost (s) = $85 per batch daily subassembly usage rate = 200carrying cost = $.20 per unit per year(a) to minimize cost, how large should each batch of subassemblies be? (b) approximately how many days are required to produce a batch? (c) how long is a complete cycle? (d) what is the average inventory for this problem? (e) what is the total annual inventory cost (holding plus setup) of the optimal behavior in this problem?

Barbara flynn is in charge of maintaining hospital supplies at general hospital. during the past year, the mean lead time demand for bandage bx-5 was 65 (and was normally distributed). furthermore, the standard deviation for bx-5 was 6. ms. flynn would like to maintain a 90% service level.refer to the standard normal table for z-values.a) what safety stock level do you recommend for bx-5? safety stock=)what is the appropriate reorder point? reorder point=

Suppose either computers or televisions can be assembled with the following labor inputs: units produced 1 2 3 4 5 6 7 8 9 10 total labor used 3 7 12 18 25 33 42 54 70 90 (a) draw the production possibilities curve for an economy with 54 units of labor. label it p54. (b) what is the opportunity cost of the eighth computer? (c) suppose immigration brings in 36 more workers. redraw the production possibilities curve to reflect this added labor. label the new curve p90.
