Homework Answers

Answer #1

average demand (d) = 175

standard deviation of demand (s) = 25

lead time (L) = 5

standard deviatio of lead time (lt) = 3

a) service level = 90%

z score using standard normal table for 90% = 1.28

ROP = d*L + z*(L*s2 + d2 * lt2)

ROP = 175*5 + 1.28*(5*252 + 1752 * 32)

= 875 + 1.28*(3125 + 275625)

= 875+1.28*528

= 875+675.84

= 1550.84 = 1551 is the ROP

b) service level 95%

z = 1.645

ROP = d*L + z*(L*s2 + d2 * lt2)

ROP = 175*5 + 1.645*(5*252 + 1752 * 32)

= 875 + 1.645*(3125 + 275625)

= 875+1.645*528

= 875+868.56

= 1743.56 = 1744 is the ROP
