Problem 2-14 As operations manager, you are concerned about being able to meet sales requirements in the coming months. You have just been given the following production report: FEB MAR APR Units produced 2,220 1,700 2,700 2,900 Hours per machine 311 189 Number of machines Find the average of the monthly productivity figures (units per machine hour). (Do not round intermediate calculations. Round your answer to 2 decimal places.) Average productivity units per machine hour Solution
JAN:
t1 = Total machine hours = 311 X 3 = 933
x1= Units produced = 2220
FEB:
t2 = Total machine hours = 189 X 5 = 945
X2= Total machine hours = 1700
MAR:
t3 = Total machine hours = 386 X 4 = 1544
X3 = Total machine hours = 2700
APR:
t4 = Total machine hours = 309 X 4 = 1236
X4 = Total machine hours = 2900
Average monthly productivity for JAN = 2220/933 = 2.3794
Average monthly productivity for FEB = 1700/945 = 1.7989
Average monthly productivity for MAR = 2700/1544 = 1.7487
Average monthly productivity for APR = 2900/1236 = 2.2463.
OVERALL Average productivity = (2220 + 1700 + 2700 + 2900)/(933+845+1544+1236)
= 9520/4658
= 2.04 units/machine hour
