a. Consider an item for which an (R, s, S) system is used. The review interval is 1 week.

Other characteristics include L = 2 weeks r = 0.26$/$/year D = 800 units/year B3 = 0.30$/$ short/week A = $20 σR+L = 14.2 units v = $1.50/unit Using the revised power approximation, find the appropriate values of s and S.

(Assume that there are exactly 52 weeks per year.)

b. Repeat for another item with the same characteristics except v = $150 /unit.  LOP52
